If you were the emergency department physician caring for this girl causes of erectile dysfunction include quizlet purchase cialis jelly 20 mg with visa, what would be your assessment and plan of action This case involves an intentional overdose situation involving a teenager which is a more difficult scenario to assess because the history that is provided is often incomplete and/or inaccurate/unreliable. For example, did she really ingest an entire box of diphenhydramine tablets as was reported Is there the possibility that she ingested other substances in addition to the diphenhydramine Is it possible that this adolescent female is pregnant and if so, are any of your therapeutic interventions contraindicated in a pregnant female The child has never had prior episodes of seizures but he has had two days of low grade fevers along with a slight cough. Although you are contemplating the possibilities of meningitis and febrile seizures in your differential diagnosis, should the possibility of a toxic ingestion/exposure also be considered in the differential diagnosis in this case This case illustrates how one must consider the possibility of a toxic exposure in the differential diagnosis of a patient who presents to the emergency department with severe, life threatening signs and symptoms. The majority (75%) of these poisoning cases that are reported to the poison control centers each year are safely and effectively managed at home with phone advice from the poison control centers poison information specialists. Therefore only 25% of the callers are actually referred to emergency departments for further assessment and treatment. Roughly 50% of the reported poisoning cases involve children under six years of age. Page 500 Poisonings can occur through a variety of different routes of exposure, but the most common route of exposure is via oral ingestions. In 2000, 86% of the reported two million human exposure cases involved unintentional/accidental exposures, while only 11% involved intentional exposures (with the majority of the intentional overdoses involving adults) (1). Up to 90% of the poisoning cases each year occur in the victims own home, while only 1% occur at schools. In 2000, the substances that were responsible for these pediatric fatalities were: methanol, crotalid snake bite, pine oil cleaner, carbon monoxide/smoke, hair oil/conditioner, kitty litter (aspiration), lead, kerosene, aluminum phosphide pesticide, paraquat pesticide, acetaminophen, methadone, morphine, amitriptyline, diphenhydramine, norfloxacin, and diphenoxylate/atropine (antidiarrheal) (1). The three clinical cases listed at the beginning of this chapter illustrate the wide spectrum of how poisoning cases may present to healthcare providers. Because it would be virtually impossible to cover every possible type of poisoning scenario that you may encounter in your career, a systematic and logical overall approach to poisonings will be emphasized throughout this chapter. Since 75% of all toxic exposures involve ingestions, this chapter will primarily focus on the assessment and management of toxic ingestions. Helpful poison prevention tips the initial management of any poisoning case must first address the assessment and stabilization of the standard "A-B-Cs" of emergency medicine. If the patient is unable to maintain and protect his or her own airway or has a diminished gag reflex, one may need to first consider endotracheal intubation prior to performing any type of gastrointestinal decontamination in order to protect the airway from aspiration. If at all possible have a family member bring the bottle, box or container of the suspected toxin to the emergency department so that you yourself can verify the specific product and active ingredients. In general, gastric lavage is not very effective if performed more than two hours post-ingestion. The level of 100 mcg/ml may not be toxic if it was obtained two hours post-ingestion, whereas the very same level would be considered toxic if it was obtained 20 hours post-ingestion. When confronted with this dilemma, the physician should always assume the worst case scenario rather than minimizing the amount that may have been potentially ingested. Although the majority of the substances that are typically ingested by children are either nontoxic or mildly toxic, there are a few substances that can potentially be fatal even when ingested in very small amounts. Some of these highly toxic substances with the corresponding amounts which could potentially be lethal for a 10 kg child are: amanita phalloides (one mushroom), amphetamines, antimalarials (one chloroquine tablet), calcium channel blockers (one nifedipine tablet), camphor (one teaspoon), clonidine (one 0. The first is that of a child who presents with a witnessed or suspected ingestion. For example if a previously healthy 2 year old child presents to the emergency department after experiencing a brief afebrile seizure, the possibility of a toxic ingestion must be included within the differential diagnosis in addition to head trauma and other various etiologies for the childs afebrile seizure. The following is my quick and easy to remember method of simplified pediatric vital signs (5). Heart rate Respiratory rate Newborn to 1 year old 140 40 1 year old to 4 years old 120 30 4 years old to 12 years old 100 20 > 12 years old 80 15 the key elements of a toxicologic physical examination include the following elements (3): a) Eyes: pupillary size, symmetry and response to light presence of nystagmus (vertical or horizontal). Toxidromes refer to a specific constellation of signs and symptoms which one may expect to see with a specific class or type of toxic substance. Toxidromes are based on the patients vital signs as well as on the physical examination findings. Gastric lavage by itself is only effective at removing toxins that are still within the stomach. In order to perform effective lavage, the internal diameter of the tube must be large enough to accommodate the pill fragments that are in the childs stomach. Thus, because large orogastric lavage tubes cannot always be safely placed in children, the option of gastric lavage may not be feasible and/or effective in smaller children. Some of the newer "super" adsorptive activated charcoal preparations reportedly have up to 2,000 square meters of adsorptive surface area per gram of charcoal. Because activated charcoal is able to prevent systemic toxicity by effectively binding so many different ingested toxins, many poison control centers have been recently recommending the administration of activated charcoal alone (without first performing gastric lavage) for ingestion cases of mild to moderate severity. Although activated charcoal has been sometimes referred to as the "universal antidote" because it adsorbs so many different toxins, there are nine scenarios in which activated charcoal may not be clinically effective. Because the majority of camphor containing products are typically found in liquid preparations, by the time the child presents to the emergency department, most of the liquid camphor has already been completely absorbed from the stomach and therefore there will be nothing left for the activated charcoal to adsorb. Multiple doses of activated charcoal (without cathartics) are sometimes used as a method of "gastrointestinal dialysis" for certain drugs that undergo enterohepatic circulation. The main role of cathartics is to more quickly eliminate the charcoal bound toxin complex from the intestines before the toxins have the opportunity to dissociate from the activated charcoal. Sorbitol also comes premixed with activated charcoal ranging from 27-48 grams of sorbitol per 120 milliliter bottle of activated charcoal. Sorbitol can be safely used in children as long as it is administered only once per 24 hours and the stool output and the cardiovascular and hydration status are closely monitored. Although there are multiple methods available to enhance the elimination of specific toxins from the body, the majority of pediatric poisoning cases can be treated with one or more of the decontamination methods mentioned above. The urinary pH can be manipulated in order to enhance the urinary excretion of certain drugs and toxins. Other more complex methods of enhanced elimination techniques include peritoneal dialysis, hemodialysis and hemoperfusion. Another very useful laboratory study is the measured serum osmolality and the serum osmolar gap. Thus a patient who has ingested one of the alcohols will typically exhibit an elevated measured serum osmolality despite a normal calculated serum osmolality. The serum osmolar gap (measured serum osmolarity minus the calculated serum osmolarity) should be <5-10 mosm/Liter. The calculated osmolar gap is also valuable in that it can also be used to predict a patients blood ethanol level via the formula: [serum osmolar gap] x [4. Since prevention is the best method of reducing accidental poisoning in children, physicians should routinely incorporate poison prevention guidelines/tips into their healthcare maintenance discussions with their parents. Some of these points are listed below: a) Keep the phone number of your local poison control center near the telephone. A mother of a 2 year old boy calls you because she suspects that her son may have eaten a few of his grandmothers "heart pills. Have the mother induce vomiting immediately by sticking her finger in the childs mouth. Advise no interventions at the present time, but also advise her that if the child should begin to develop any symptoms to go to the emergency department for further treatment. The gastrointestinal decontamination method of choice for a child who presents to the emergency department with multiple episodes of vomiting two hours after ingesting a toxic amount of iron is: a. A parent suspects that her 18 month old son may have accidentally ingested a few pellets of rat poison. Rush her son to the nearest emergency department for immediate gastric lavage and activated charcoal. Clinical pearls in pediatric toxicology: A systematic approach to the poisoned child.

If a 3:1 ketogenic diet has multiple mechanisms of action that sum(fat-to-nonfat) ratio is insufficient to produce the required mate and account for its rather unique therapeutic properties. Further basic science experiments will help to elucidate other novel effects of the ketogenic diet.

Urine 3:1 diet is then equal to 31 calories: ketones may be misleading and should not be monitored if blood measurements are available. This allows metabolic adaptation to the state of requirements of calories by this figure of 31 calories/unit, Chapter 69: the Ketogenic Diet 793 which generates the number of units required for the day: Termination of the Ketogenic Diet 1000 calories/day = 32. A sudden stop 31 calories/unit of the diet or sudden administration of glucose may aggravate seizures and precipitate status epilepticus (41). Livingston Next, multiplying by 27 calories of fat/unit provides the daily advocated maintaining the diet at a ratio 4:1 for 2 years and, if fat requirement: successful, weaning down to a 3:1 diet for 6 months, followed 32. At this point, a regular diet is 871 calories of fat/day, which is equivalent to 96 g.

Examples are: sildenafil (Viagra, Revatio), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) which are used for erectile dysfunction and pulmonary hypertension. Also avoid use in patients receiving intravenous epoprostenol (Flolan) or treporstenil (Remodulin) which is used for pulmonary hypertension. Nitroglycerin reduces left ventricular filling pressure primarily via venous dilation. At higher doses the drug variably lowers systemic afterload and increases stroke volume and cardiac output. Pulmonary edema is more commonly a problem of volume distribution than overload, so administration of furosemide provides no immediate benefit for most patients. High-dose nitrates can reduce both preload and afterload and potentially increase cardiac output. A concern with high doses of nitrates is that some patients are very sensitive to even normal doses and may experience marked hypotension. It is therefore critical to monitor blood pressure during high-dose nitrate therapy. Effectiveness of prehospital continuous positive airway pressure in the management of acute pulmonary edema.

An example of an appropriate format for a filter paper blood collection card is shown in Figure 13 erectile dysfunction filthy frank cheap 20 mg cialis jelly mastercard. The filter paper should be allowed to dry thoroughly (at least 60 minutes) before enclosing it in a bag for storing. Drying stabilizes the IgM and reduces the chance of microbiological contamination. Each filter paper should be wrapped individually, preferably in a sealable plastic bag to prevent possible cross contamination and to protect from dust and moisture. Although samples do not need to be kept refrigerated or frozen during transport, it is advisable to store in a cool place and transport to the laboratory as soon as possible. For safety reasons, dried blood spots should be always considered as potentially infectious and only be handled with gloves. The swabs are designed to be used like a toothbrush and should be rubbed along the gum until the swab is thoroughly wet. The wet swab is placed inside the clear plastic transport tube that has an area on the outside to write the name of the patient, patient details and collection date. Some devices have virus transport medium incorporated within the plastic transport tubes, others can be transported as is. At higher temperatures samples should be kept in a refrigerator until shipping to the laboratory on ice. The samples are usually not considered biohazardous and can be shipped without special documentation from the site of collection to the laboratory. Oral fluids must be extracted from the sample swabs as soon as possible after receipt in the laboratory. This should have a surface covering that can be easily disinfected using common laboratory disinfectants (70% alcohol, sodium hypochlorite solution, 2% glutaraldehyde solution, etc. Unpacking and recording of specimens should preferably be carried out by two persons: one records data while the other is gloved and is responsible for opening the package and checking for breakage and leakage of sample containers, and contamination of accompanying documents. Copies of all paperwork regarding the shipment should be maintained, especially permits. It is recommended that each laboratory develop specific standard operating procedures for opening packages and logging in specimens. Laboratory diagnosis of measles and rubella Detection of measlesor rubella-specific immunoglobulin M (IgM) in serum is the standard test for the rapid laboratory diagnosis of measles and rubella. A number of commercially available IgM assays for measles and rubella use the indirect format. This format requires the blockage of IgG antibodies and rheumatoid factor through a pre-treatment step to ensure optimal performance. IgM assays based on the capture format have been developed for both measles and rubella. Although no longer routinely used for diagnosis of acute measles and rubella infection, detection of a rise in specific IgG in serum samples collected during the acute and convalescent phases, can be used to confirm infection. IgG assays rely on the collection of two samples about 10 to 30 days apart, and can also be used for confirmation of sporadic cases of IgM positive or equivocal results in elimination phase countries. Although not recommended for routine laboratory diagnosis, culture of measles and rubella virus from clinical specimens is an important component of measles and rubella control strategies. Viral antigen is then added and allowed to bind to any virus-specific IgM present. After washing, bound antigen is detected using anti-virus monoclonal antibody conjugated with an enzyme, following which a detector system with chromogen substrate reveals the presence or absence of virus-specific IgM in the test sample. In some formats, the antigen-monoclonal antibody-enzyme complex is premade, eliminating one binding and washing cycle. This test for measles is available commercially in kit form from numerous companies, however not all have been evaluated for use in the Measles and Rubella Laboratory Network. The first step of the absorption of virus antigen onto the solid phase is usually completed by the manufacturer and provided ready for use. The patients serum is then added and any virus-specific antibody (IgM and any non-absorbed IgG) binds to the antigen. IgM antibody is detected either directly, by means of an enzyme-labelled anti-human IgM monoclonal antibody or indirectly by means of anti-human IgM monoclonal antibody plus enzyme-labelled anti-mouse antibody. A chromogen substrate is added to reveal the presence of virus-specific IgM in the test sample. Use of the alternative sampling methods of dried blood spot collection requires modification of the standard IgM assay procedures. Eluted fluid from dried blood spots can be tested using commercially available IgM indirect assays (such as those produced by Dade Behring), using slightly modified procedures [39]. Laboratories in Regions without a rubella elimination target may still test samples for rubella, depending on the existing epidemiology of rubella and the status of rubella control activities, primarily because suspected measles cases are sometimes rubella cases. Since testing kits for rubella IgM detection are usually more expensive than measles, and testing all samples for both measles and rubella is often not a feasible option, a strategy of first testing all samples for measles IgM, and testing only measles IgM-negative samples for rubella IgM is an effective use of resources (Figure 16 A). Laboratories in countries with an effective measles immunization programme, and consequently a very low incidence of measles, but with no or very low rubella immunization, can make best use of resources by testing samples from rash/fever (or suspected measles or rubella) cases first for rubella IgM and then testing rubella IgM-negative samples for measles IgM (Figure 16 B). Measles/rubella IgM testing strategies under different disease control conditions A. Single blood sample collected <28 days Serum from suspected measles Measles IgM test case Positive Negative Confirm measles Rubella IgM test positive Positive Negative Confirm rubella Discard positive B. For countries with very low incidence of measles and no or low rubella immunization Serum from suspected rash/fever case Rubella IgM test Positive Negative Confirm rubella Measles IgM test positive Positive Negative Confirm measles Discard positive 44 Manual for the laboratory diagnosis of measles and rubella virus infection Second edition 5. Serological techniques cannot distinguish between the immune response to natural infection and immunization, this can only be accomplished by viral isolation and characterization. In tropical environments, approximately one third of primary dengue virus infections can present with rash and fever[47], accounting for the vast majority of rash and fever cases seen in dengue epidemic periods. It is therefore recommended that IgM-positive cases with a history of measles and/or rubella vaccination in the 1 to 6 weeks prior to rash onset can be discarded after thorough epidemiological investigation and no evidence is found of other confirmed cases in the vicinity or an epidemiological link to confirmed cases elsewhere. The most common causes for false positive reactions include the presence of rheumatoid factor, specific IgG, and non-specific, cross-reacting IgM in the samples. In response to measles and rubella infections and vaccinations, specific IgM levels usually fall to below the level of detection within 1 to 2 months [49]. As it can often be difficult to obtain a second sample, IgM tests on a single sample are recommended. However, if the IgM test results remain inconclusive, a second (convalescent) serum specimen, collected 10-30 days after the first (acute) specimen, can be used to test for an increase in the IgG titre. However the first serum sample should be collected within the first 10 days after rash onset and IgG testing for laboratory confirmation of measles or rubella requires the demonstration of a 4-fold rise in the titre of antibody against measles or rubella. The tests for diagnostic IgG antibody should be conducted on both acute and convalescent specimens at the same time using the same type of test. In these assays, purified virus antigen is adsorbed onto a solid phase and the patients serum is added. Any virus-specific antibody binds to the antigen, and virus-specific IgG is detected using anti-human IgG. The binding of virus-specific IgG is measured by a direct or indirect detector system using a chromogen substrate. Depending upon the strength of this binding, the complex formed may or may not be easily dissociated. Antibody avidity is low after primary antigenic challenge, becomes higher with time and it usually involves IgG antibodies[51, 52]. Assays measuring the antigen-binding avidity of IgG antibodies has been developed to distinguish the low-affinity antibodies produced at an early stage of infection from those with a higher-binding affinity that reflects past immunity. IgG avidity testing can be helpful in differentiating between primary and secondary rubella infections, and in excluding the possibility of residual IgM months or years after primary infection. However, IgG avidity assays are difficult to establish, standardise, quality control and interpret, and are recommended only for laboratories experienced in using these assays. This database of sequence information now makes it possible to use molecular epidemiological techniques to identify the source of wild-type viruses and to differentiate between wild type and vaccine strains.

In one study erectile dysfunction disorder generic 20 mg cialis jelly fast delivery, a total of 47% (27/58) of breakthrough cases had <50 lesions compared with 8% (7/92) in unvaccinated individuals, and 7% (4/58) of breakthrough cases had >300 lesions compared with 50% (46/92) in unvaccinated individuals . Among a subset of vaccinees who were actively followed in these early trials for up to nine years postvaccination, 179 individuals had household exposure to varicella. There were no reports of breakthrough varicella in 84% (150/179) of exposed children, while 16% (29/179) reported a mild form of varicella (38% [11/29] of the cases with a maximum total number of <50 lesions; no individuals with >300 lesions). This represents an 81% reduction in the expected number of varicella cases utilizing the historical attack rate of 87% following household exposure to varicella in unvaccinated individuals in the calculation of efficacy. In those who developed breakthrough varicella postvaccination, the majority experienced mild disease, with the median of the maximum total number of lesions <50. The severity of reported breakthrough varicella, as measured by number of lesions and maximum temperature, appeared not to increase with time since vaccination. Among a subset of vaccinees who were actively followed in these later trials for up to 10 years postvaccination, 95 individuals were exposed to an unvaccinated individual with wild-type varicella in a household setting. There were no reports of breakthrough varicella in 92% (87/95) of exposed children, while 8% (8/95) reported a mild form of varicella (maximum total number of lesions <50; observed range, 10 to 34). Subjects were actively followed for varicella, any varicella-like illness, or herpes zoster and any exposures to varicella or herpes zoster on an annual basis for 10 years after vaccination. Most cases of varicella reported in recipients of 1 dose or 2 doses of vaccine were mild . The estimated vaccine efficacy for the 10-year observation period was 94% for 1 dose and 98% for 2 doses (p<0. A total of 50 clinical varicella cases were reported >42 days following 2-dose vaccination. Based on passive follow-up, the annual varicella breakthrough event rate ranged from <0. Among the subset of vaccinees who were actively followed in these early trials for up to six years, 76 individuals had household exposure to varicella. There were no reports of breakthrough varicella in 83% (63/76) of exposed vaccinees, while 17% (13/76) reported a mild form of varicella. Among 13 vaccinated individuals who developed breakthrough varicella after a household exposure, 62% (8/13) of the cases reported maximum total number of lesions <50, while no individual reported >75 lesions. The attack rate of unvaccinated adults exposed to a single contact in a household has not been previously studied. Utilizing the previously reported historical attack rate of 87% for wild-type varicella following household exposure to varicella among unvaccinated children in the calculation of efficacy, this represents an approximate 80% reduction in the expected number of cases in the household setting. A total of 3 clinical varicella cases were reported >42 days following 2-dose vaccination. Among the subset of vaccinees who were actively followed in these later trials for up to five years, 16 individuals were exposed to an unvaccinated individual with wild-type varicella in a household setting. One-Dose Regimen in Children In prelicensure efficacy studies, seroconversion was observed in 97% of vaccinees at approximately 4 to 6 weeks postvaccination in 6889 susceptible children 12 months to 12 years of age. The average antibody response in vaccinees who received the second dose 8 weeks after the first dose was higher than that in vaccinees who received the second dose 4 weeks after the first dose. A boost in antibody levels has been observed in vaccinees following exposure to wild-type varicella, which could account for the apparent long-term persistence of antibody levels in these studies. Seroconversion rates and antibody levels to measles, mumps, rubella, and varicella were comparable between the two groups at approximately six weeks postvaccination. No clinically significant differences were noted in adverse reactions between the two groups. No clinically significant differences in adverse reactions were seen between the two groups. There were no clinically important differences in reaction rates when the three vaccines were administered concomitantly versus six weeks apart.

Hypoglycemia is not always present in patients with congenital adrenal hyperplasia and salt-wasting crisis, but it can occur. To discourage the use of the term amp, our practice is to state that we do not have adult amps available at this time. Although polyingestions are more common in adolescents, most of the listed drugs above are high-risk, treatable entities. Laboratory results should be ready for the students and are best given to them on a slip of paper (as opposed to verbally provided by the instructor). Deferoxamine therapy is not without risks (hypotension), and poison control consultation is recommended even if the team were to come up with this treatment on its own. Metabolic derangements, both inborn errors and those due to ingestions, can mimic sepsis. An actor or confederate nurse can be used to report a palpable enlarged liver and prolonged capillary refll. The case can be tailored to your institutional practice, as it pertains to rapid sequence drug choices, endotracheal tube type (cuffed or not), use of mannitol or other osmotic agents, or short-term mild hyperventilation. This case is written to be only mildly suggestive of non-accidental trauma to prevent immediate identifcation of the problem to the exclusion of all other causes. Similarly, a bulging fontanelle (which might be present in a patient) is often so obvious on some simulators as to be a distractor and should be used at the instructors discretion after evaluating this functionality on the simulator device to be used. The role of sonography for trauma is not yet broadly established in pediatrics at this time and is not discussed here. This patient has a grade 5 liver laceration that is currently not causing hemodynamic issues. In this case, treatment can be stopped before intubation, and this material can be reviewed as discussed in the text. A dressing or bandage should be applied to the chest to mimic recent cardiac surgery or sternotomy scar. Instructors should encourage students to prepare epinephrine (adrenaline), amiodarone, and lidocaine (lignocaine) immediately on recognition of the rhythm. Infants and small children should always receive resuscitation fuids using either a pump or push to allow for observation and control of fuid delivery. Participants should recognize and anticipate that infant and pediatric pressor drips must be prepared individually for a patients weight and are not stock items because these items are for adults. Depending on the institution, there might be a signifcant delay in preparation and delivery of pressor drips. Albuterol (salbutamol) and ipratropium bromide should ideally be administered via metered-dose inhaler. If your institution uses fosphenytoin, consider having the patient be normotensive and instead focus on airway management of the seizing patient. This case can be changed to have foreign body below the vocal cords and having the participants intubate and push the foreign body into the right mainstem bronchus. The point of having the removable foreign body is to reinforce the Magill forceps as a useful tool.

A largely based on landmark Veterans Administration significant difference between treatment groups was observed Cooperative trials (91,92) and similar open-label trials in the for patients with one or two seizures in the 3-month baseline, United Kingdom (93,94). This finding suggested that higher seizure frequency blind trials demonstrating a statistically significant difference may serve as an indicator of more treatment-resistant seizures between treatments as evidence of efficacy, generating considin patients with untreated epilepsy and is consistent with other erable debate as to how to safely and ethically accomplish this reports linking higher seizure frequency before initial treatgoal. One such approach is an active-control conversion-toment with refractory epilepsy (102). Similar results were observed for time to first analyses for time to first seizure showed a significantly greater seizure.

This added to carbamazepine in patients with uncontrolled partialcan often be ameliorated by slowing the rate of titration.

The signs and symptoms of biliary atresia will be dependent upon the time of presentation icd 9 code for erectile dysfunction due to medication order cialis jelly without prescription. Jaundice can be present at birth or it can present as late as 3 to 5 weeks of life. There can be some pigment in the stool due to sloughing of cells that contain pigments. Since the bile pigments are no longer released into the stool, they will be deposited in the urine leading to darker urine. The presence of splenomegaly is variable and more common with later presentations as part of the constellation of portal Page 343 hypertension. Later presentations are associated with the progression of the disease to biliary cirrhosis and the development of portal hypertension with failure to thrive (2). Alkaline phosphatase will be highly elevated reaching levels higher then 5 times normal (2). There have been diseases that are now described that were once under the heading of idiopathic neonatal hepatitis such as alpha-1-antitrypsin deficiency. These patients tend to present with low birth weight, early onset of jaundice, and usually have pigmented stools (2). Laboratory findings include elevations in the serum aminotransferases and bilirubin. These are characterized by the absence or marked decrease in the number of intrahepatic interlobular bile ducts, with normal sized arteries and portal veins in the triad. Intrahepatic bile duct paucity was previously referred to as "intrahepatic bile duct atresia" or "intrahepatic biliary atresia" (6, 8). These diseases are diagnosed by the presence of cholestasis and bile duct paucity on liver biopsy. The non-syndromic form describes a common pathology with various etiologies, which are still poorly understood. For example in Alagille syndrome, or arteriohepatic dysplasia, there are characteristic facies along with ocular, cardiovascular, vertebral, and kidney pathology. When a child presents with jaundice, the first step is to evaluate the total and fractionated bilirubin in each patient with jaundice. If the elevation is isolated to the unconjugated (indirect) fraction of bilirubin then significant liver pathology is unlikely (3). However, if the elevation is in the conjugated (direct) fraction or it is 20% or greater of an elevated total bilirubin then cholestasis more likely (6). Findings include edema of the portal tracts, tortuous proliferation of bile ductules, fibrosis, along with intracellular and canalicular cholestasis. There is also a mixed infiltration of neutrophils and lymphocytes with a mild non-specific cholangitis (7). If an intact extrahepatic biliary system is not visible, then extrahepatic biliary atresia is evident. A patent biliary system visualized on the intraoperative cholangiogram rules out extrahepatic biliary atresia. If the intrahepatic bile ducts are obliterated or reduced in number, then bile duct paucity (formerly called intrahepatic biliary atresia), is present. Page 344 Diagnostic algorithm of biliary atresia: 1) Direct hyperbilirubinemia prompts evaluation and lab work-up. The Kasai procedure is the Roux-en-Y hepatoportoenterostomy where the porta hepatis is attached to a loop of bowel after resection of the fibrotic biliary system. This procedure basically anastomoses the liver directly to the bowel so that in theory, bile can flow from the liver into the bowel. The reason that the procedure succeeds is that at the porta hepatis there are microscopic bile ductules that have proliferated which communicate with the intrahepatic system. Some groups use frozen section biopsy during the laparotomy to examine the tissue at the porta hepatis using the size of the vessels as a marker for the likelihood of successful reestablishment of bile flow. To obtain maximum benefit from the Kasai procedure it should be performed before the patient is 3 months old, ideally less then 2 months. Establishment of bile flow is achieved in 80% of the patients who are less then 2 months, 50% between 2 and 3 months, and less then 10% if older then 3 months (12). Outcomes of the procedure and post-procedure survival are improved when the hospital does more then 5 procedures a year (1,5,13). If the child is diagnosed at an age greater then 3 months, the Kasai procedure has a low probability of success. While a post Kasai transplant is technically more difficult, there was no reported change in survival after transplantation in patients who underwent primary transplantation versus those who had a failed Kasai procedure prior to transplantation (11,13). In the Kasai procedure, the bowel contents containing digestive enzymes have direct access to the existing bile ducts and hepatic tissue causing the cholangitis. An anti-refluxing valve can be surgically created within the duodenal segment anastomosed to the liver, but such alterations in the Kasai procedure and various medical regimens have not proven successful. Prophylactic antibiotics with trimethoprim-sulfamethoxazole is designed to reduce bowel bacterial counts. The portal hypertension that develops will have the sequelae of other forms of portal hypertension such as varices, ascites, hypertensive gastropathy, hypersplenism, and encephalopathy (1). The most common presentation is esophageal variceal hemorrhage occurring in 3060% of patients (1). The first group are the patients who produce adequate bile flow and are relieved of their jaundice. The second group has moderate bile flow but they remain jaundiced and will continue to survive postKasai, however they will eventually need liver transplantation later in life. This is considered a failure of the Kasai procedure and they will need liver transplantation in order to survive. While the Kasai procedure establishes bile flow, it does not necessarily halt the intrahepatic inflammation and fibrosis. Patients who undergo the Kasai procedure can survive with their native liver in 20-30% of cases, but the remainder will eventually need liver transplantation (2,10). Survival with ones native liver at 5 years has been reported to be as high as 32% in recent studies and 27% at 10 years (5,13). Despite this, there are still many children who are untreated at 3 months of age (as high as 14-19% in some studies) (1). A liver biopsy shows hepatocellular ballooning and the presence of multinucleated giant cells. A patient presents to you with lightly colored stool; however, when the stool is broken up it is noticed that the center is clay colored. A 16 week old patient is diagnosed with biliary atresia, should he/she undergo a Kasai procedure if there are no contraindications or should the patient just wait for a liver transplant Is the Kasai Operation Still Indicated in Children older then 3 months diagnosed with Biliary Atresia Since there is little risk involved, the threshold to obtain a serum fractionated bilirubin should be low. If there is an elevation of conjugated bilirubin at 14 days of age or earlier, it is by definition neonatal cholestasis. However, it is also consistent with idiopathic neonatal hepatitis and therefore a definitive diagnosis can not be made on this biopsy result alone. The superficial light coloring is due to the sloughing of pigmented cells during the transit in the bowel and does not affect the core of the stool. While there is little chance of long-term survival with the patients native liver in someone who undergoes the Kasai procedure after 3 months of age, there is some benefit. The Kasai procedure can lead to extended survival time with the native liver, allowing the patient to stabilize baseline health. There is also a benefit in that there will be longer period of time to find a donor and prepare the patient for transplantation. Her urine color is darker than normal, although she has not been drinking much fluid. Her liver edge is palpable 5 cm below the right costal margin, and is moderately tender. On further questioning, it is discovered she ate at a restaurant one month ago where a worker was found to have hepatitis A. It manufactures proteins such as albumin, prothrombin, fibrinogen, transferrin, and glycoprotein from amino acids. The cytochrome P-450 system is responsible for the detoxification of many different compounds. Therefore, diseases that damage the liver can have a very detrimental effect on the body.

Allow the patient to be in their position of comfort to maximize their breathing effort how is erectile dysfunction causes order cialis jelly with amex. Avoid hyperventilation as it increases intrathoracic pressures, potentially worsening hemodynamic instability. If symptomatic and hemodynamically unstable: Synchronized cardioversion: Follow manufacturers recommendations for dosing. Consider administer of one of the following prior to or during cardioversion, if feasible: o Midazolam 2. If symptomatic, but hemodynamically stable: For narrow complex tachycardia (with a heart rate persistently >150bpm): Attempt vagal maneuvers, for regular rhythms. Medications should be administered cautiously in frail or debilitated patients; lower doses should be considered. Wide complex tachycardia should be considered Ventricular Tachycardia until proven otherwise Signs and symptoms of hemodynamic instability: o Hypotension o Acutely altered mental status o Signs of shock o Signs of acute heart failure o Ischemic chest pain Adenosine should be administered rapidly though a proximal. If adenosine is ineffective or for wide complex, perform synchronized cardioversion: o 1 J/kg; if unsuccessful, increase to 2 J/kg. Consider administration of one of the following prior to or during cardioversion, if feasible: o Midazolam 0. Assess the patients airway for evidence of smoke inhalation or burns: soot around mouth or nostrils, singed hair, carbonaceous sputum, see Smoke Inhalation Protocol 2. If a partial thickness burn (2nd degree) is <10% body surface area, apply roomtemperature water or room-temperature wet towels to the burned area for a maximum of 15 minutes. For suspected or verified Hydrofluoric Acid skin exposure: a) Apply gauze soaked with 2. Consider spinal motion restriction for electrical burns that result in hand to hand flow. If a partial thickness burn (2nd degree) is <10% body surface area, apply room-temperature water or room-temperature wet towels to the burned area for a maximum of 15 minutes. Patients who sustain an electrical burn should be placed on a cardiac monitor Consider spinal motion restriction for electrical burns that result in hand to hand flow. Consider spinal motion restriction for suspected spinal injury, see Spinal Trauma Protocol 4. Conscious patients with submersion injuries should be transported to the hospital. Chemical irritants, including pepper spray: flush with copious amounts of water, or normal saline. If the patient cannot close their eyelids, keep their eye moist with a sterile saline dressing. Dental avulsions should be placed in an obviously labeled container with saline soaked dressing, milk, or cell-culture medium (example: Save-a-tooth). Avoid touching the root of the tooth (the part of the tooth that was embedded in the gum) because it can be damaged easily. Remove obvious debris, irrigate open wounds with saline solution, and cover with moist sterile dressing. Assess Circulation-Sensory-Motor distal to injury before and frequently after immobilization. Stabilize suspected pelvic fractures in the presence of hypotension or other signs of shock with an appropriate commercial device (preferred) or bed sheet. Paramedics may straighten severely angulated fractures if the distal extremity has signs of decreased perfusion. Paramedics may contact Direct Medical Oversight for any other reductions not meeting this protocol. For dislocations due to direct impact, such as falls, the injury is more likely to be complicated by a fracture. Fractures of the humerus, pelvis and femur, as well as fractures or dislocations involving circulatory or neurological deficits, take priority over other musculoskeletal injuries. Hip dislocations, pelvic, knee, and elbow fracture / dislocations have a high incidence of vascular compromise. Neurogenic shock: May occur after an injury to the spinal cord disrupts sympathetic outflow resulting in unopposed vagal tone. Control active bleeding using direct pressure, pressure bandages, tourniquets (commercial preferred) see Tourniquet Procedure 6. Do not delay transport; consider hospital destination per Trauma Triage and Transport Decision Protocol 6. Total volume should not exceed 2000 mL without consultation with Direct Medical Oversight. If cardiac tamponade is suspected, rapid transport and treat arrhythmias per Cardiac Protocols 3. Hemostatic bandages must be non-exothermic type that washes off with normal saline. Delaying aggressive fluid resuscitation until operative intervention may improve outcome. Patients should be reassessed frequently, with special attention given to the lung examination to ensure volume overload does not occur. Patients without any of the above findings should generally be transported without the use of a cervical collar or other means to restrict spinal motion. Utilize spinal motion restriction only where, in the professional judgment of the provider, the patient is at high risk for spinal injury or displays clinical indications of injury. When possible, the highest level provider on scene should determine whether spinal motion restriction is to be used or discontinued (collar removed, etc. When spinal motion restriction has been initiated and a higher level provider arrives, patients should be reassessed for spinal injury (as described in this section) to determine the most appropriate ongoing care. A long backboard, scoop stretcher, vacuum mattress, or other appropriate full length extrication device may be used for extrication if needed. For ambulatory patients, allow the patient to sit on the stretcher, and then lie flat. Pull sheets, other flexible devices, scoops and scoop-like devices should preferentially be utilized to move non-ambulatory patients when appropriate. Patients should only be transported to the hospital on a rigid vacuum mattress or hard backboard if removal would delay transport of an unstable patient or it is necessary for other treatment priorities. Lay the patient flat on the stretcher, secure firmly with all straps, and leave the cervical collar in place. Elevate the back of the stretcher only if necessary to support respiratory function, patient compliance or other significant treatment priority. Patients with nausea or vomiting may be placed in a lateral recumbent position maintaining the head in a neutral position using manual stabilization, padding, pillows, and/or the patients arm. Transfer from ambulance to hospital stretchers and vise-versa should be accomplished while continuing to limit motion of the spine. Long backboards do not have a role for patients being transported between facilities. If the sending physician requires a long backboard be used, it should be padded to minimize patient discomfort. Spinal motion restriction may limit respiratory function with the greatest effect experienced by geriatric and pediatric patients restricted to a long spine board. Combative patients: Avoid methods that provoke increased spinal movement and/or combativeness. Additional movement will not worsen an already catastrophic spinal injury with neurological deficit. Emphasis should be on airway and breathing management, treatment of shock, and rapid transport to a level 1 or 2 trauma center. Utilize pediatric restraint systems for older/larger children when appropriate and they fall within the devices recommended range. Apply padding and cervical collar as tolerated to minimize the motion of the childs spine. Rolled towels may be used for very young children or those who do not tolerate a collar. In a motor vehicle crash infants and children may remain in their own child safety seat, provided all of the following conditions are met: 1) the seat has a self-contained harness; 2) It is a convertible seat with both front and rear belt paths; 3) Visual inspection, including under movable seat padding, does not reveal cracks or deformation; 4) Vehicle in which safety seat was installed was capable of being driven from the scene of the crash; 5) Vehicle door nearest the child safety seat was undamaged; 6) the airbags (if any) did not deploy; 7) Provider ensures appropriate assessment of patient posterior.

The mast cells in the human conjunctiva tend to be centered just beneath the basal epithelial cell layer and around blood vessels erectile dysfunction treatment devices discount 20 mg cialis jelly amex. The allergic inflammation starts the same as in the nose when allergens bind to the cell-attached IgE molecules and then mediators are released from the cells. Most of the allergic reactions are mediated through the effects of histamine on H1 receptors which are found the conjunctiva, cornea, and ophthalmic arteries. The early phase is induced by mediators such as histamine, prostaglandin, neuropeptides and leukotrienes released by the mast cells. Histamine also induces cholinergically mediated reflex glandular secretions, which can be inhibited by atropine or ipratropium. After several hours of allergen exposure, other inflammatory cells including eosinophils, neutrophils and activated lymphocytes are demonstrable in the last phase response. The late phase or cellular phase leads to a recrudescence of nasal or eye symptoms associated with a second rise in histamine occurring in some affected persons. Eosinophil activation and accumulation with the release of eosinophilic proteins and mediators are the cause of increasing nasal blockage and hypersensitivity. Perennial allergic rhinitis is characterized by intermittent or continuous nasal symptoms resulting from indoor allergen exposure (house dust mites, animal fur) without seasonal variation. Nasal obstruction may be the major or sole complaint of the perennial type, particularly in children, in whom the nasal passage is relatively small. Lacrimation, sneezing, clear rhinorrhea and itching of the nose, ears and throat may also occur. The decreased severity of the symptoms seen in these patients may lead them to interpret their symptoms as resulting form "sinus trouble" or "frequent colds". In reality, the differentiation of seasonal and perennial types may not be clearly defined. A horizontal nasal crease, caused by upward rubbing of the nose due to itching (allergic salute), is usually seen in children. The pale or bluish nasal mucosa with variable degrees of swelling and nasal blockage, and clear watery or yellow nasal secretions may be seen. The appearance of dark circles under the eyes (allergic shiners) is due to venous engorgement secondary to nasal congestion. Posterior pharyngeal lymphoid hyperplasia secondary to postnasal drip is also noted. Middle ear fluid (otitis media with effusion or serous otitis media) is commonly noted. Corneal symptoms, including photophobia and blurring of vision, are reported in rare cases. The onset of symptoms is seasonally related to specific circulating aeroallergens. Lid edema sometimes occurs, as well as papillary hypertrophy along the tarsal conjunctival surface (the palpebral surface may appear bumpy). Do the symptoms cause a major impact on lifestyle such as school activity or sleeping Skin testing is the most common test for the diagnosis of allergy because of its simplicity, high sensitivity, low cost and rapidity of the result. Prick testing is widely used by allergists since the test is quick, not painful, inexpensive, highly specific with a low risk of systemic reaction. Patients should be instructed to discontinue some medications inhibiting skin response for a period of time including tricyclic antidepressants (5 days), hydroxyzine (3 days), astemizole (60 days), and other antihistamines (3 days). A response to an allergen with a wheal size greater than 3 mm in diameter indicates a positive result and having a specific IgE to the allergen. Appropriate in vitro tests correlate up to 70-80% of the time with prick skin tests. Structural and mechanical conditions that may mimic perennial allergic rhinitis include a deviated nasal septum, hypertrophic turbinates, adenoid hypertrophy, foreign bodies and tumors. Drug-induced rhinitis is associated with use of various oral agents, especially certain classes of antihypertensive betablockers, oral contraceptives, chlorpromazine, aspirin and overuse of topical (nasal drops and sprays) sympathomimetics (rhinitis medicamentosa). Other less-common causes of rhinitis include occupational exposure, hormones, food and alcohol. Several eye diseases need to be differentiated in patients with allergy and ocular symptoms. The symptoms include significant itching, burning and redness, eventual fibrosis, decreased keratinization of conjunctival surfaces, cataract formation and lid malposition. Vernal keratoconjunctivitis is a chronic form of allergic conjunctivitis characterized by large "cobblestone" papillae on the underside of the eyelid. Giant papillary conjunctivitis, a non-allergic condition, may be confused with ocular allergy. The management of allergic rhinoconjunctivitis in children includes allergen avoidance and education, medications and allergen immunotherapy as in adults. Allergen avoidance and environmental control: A wide range of allergens have been associated with allergic rhinoconjunctivitis, of which house dust mites are clearly the most important. Other recommendations for dust mite control are: 1) Washing the blankets, bed linen or other washable material such as curtains and toys in hot water over 55 degrees C regularly once a week. If it is impossible to remove the carpet, the carpet can be completely covered by polyethylene sheeting. Cat and dog fur is one of major allergens implicated in causing the perennial type. The allergens are not the dander itself but are contained in the saliva and in sebaceous secretions, which can flake off in small particles and remain airborne for considerable periods of time. This results in a ubiquitous allergen that can be found in many public places, even in a cat-free or dog-free buildings and schools. The only effective measure for avoiding the allergens in the home is to remove the pets, carefully vacuum and clean all carpets, mattresses and upholstered furniture. Outdoor allergens, such as pollens, grass and fungal spores, are difficult to avoid. Outdoor exercising in the morning for sufferers with pollen allergy is recommended. These sufferers should be reminded to keep their bedroom window closed during the daytime and open windows only at night when the pollen count is low. Medical treatment for allergic rhinitis: It should be noted that there are only a few medications that have been tested in children under the age of two years. In young children under the age of four, use of nasal saline drops or spray can simply comfort them and help to clear their nose before eating or sleeping. The most important aspects are the antihistamine side effects on the cognitive functions of pre-school and school children. The use of systemic corticosteroids such as oral or depot-preparations should be deferred due to their systemic adverse effects. Children with allergic rhinitis who are athletes should be advised about the medications used since some of these medications are prohibited by various sports organization. Alpha-adrenergic agonists and systemic decongestants (both often combined with H1-antihistamines) are often prohibited in organized youth sports since they have a central stimulant effect. For intranasal corticosteroid use, a medical certificate documenting medical necessity should be issued. All H1 antihistamines are competitive antagonists of histamine and are rapidly absorbed from the gastrointestinal tract. Therefore, as a rule, they are more effective in acute, seasonal allergic rhinitis than in the perennial form in which congestion or stuffiness is usually more prominent. Some of the commonly used first generation antihistamines are triprolidine, diphenhydramine, chlorpheniramine, azatadine and hydroxyzine. Their use should be restricted to two relatively uncommon situations: 1) Children with urticaria or atopic dermatitis whose pruritus is so severe that the sedation produced by an old H1-antagonist, such as diphenhydramine or hydroxyzine, is a benefit rather than a risk. However, the use of an antihistamine with decongestant is limited to children older than 12 years. Intranasal corticosteroids ("steroids" for short) have proved to be the most effective class of drugs in reducing the symptoms of allergic rhinitis. Intranasal steroids have been considered as second line agents after antihistamines by many physicians; however, first-line use of intranasal steroids is becoming increasingly common, especially for patients with moderate to severe symptoms. Intranasal steroids are more efficacious in chronic symptom relief than oral antihistamines, decongestants and cromolyn except for eye symptoms. Although no well controlled study of a combination use of steroids and other medications is published, in clinical practice, intranasal steroids can be used in combination with other therapies to achieve optimal improvement in overall symptoms.

Consider medications to reduce agitation and other significant sympathomimetic findings for the safety of the patients and providers erectile dysfunction drugs over the counter uk buy cialis jelly 20 mg with visa. This may improve behavior and compliance [see Agitated or Violent Patient/Behavioral Emergency guideline] a. Do not use promethazine if haloperidol or droperidol are to be or have been given. If hyperthermia suspected, begin external cooling Patient Safety Considerations 1. Apply the least amount of physical management devices that are necessary to protect the patient and the providers [see Agitated or Violent Patient/Behavioral Emergency guideline] 2. Recognition and treatment of hyperthermia (including sedatives to decrease heat production from muscular activity) is essential as many deaths are attributable to hyperthermia 2. If law enforcement has placed the patient in handcuffs, this patient needs ongoing physical security for safe transport. Have law enforcement in back of ambulance for the handcuffed 253 patient or make sure proper physical management devices are in place before law enforcement leaves and ambulance departs from scene 3. Vasospasm is often the problem in this case as opposed to a fixed coronary artery lesion b. If the patient is on psychiatric medication, but has failed to be compliant, this fact alone puts the patient at higher risk for excited delirium 3. If the patient is found naked, this may elevate the suspicion for stimulant use or abuse and increase the risk for excited delirium. Neuroleptic malignant syndrome, serotonin syndrome and excited delirium can present in with similar signs and symptoms 4. If polypharmacy issuspected, hypertensionand tachycardia areexpectedhemodynamic findings secondary to increased dopamine release. Stimulus reduction from benzodiazepines, anti-psychotics, and ketamine will improve patients vital signs and behavior 5. Be prepared for the potential of cardiovascular collapse as well as respiratory arrest 6. A 9-state analysis of designer stimulant, bath salt, hospital visits reported to poison control centers. Revision Date September 8, 2017 255 Cyanide Exposure Aliases Cyanide, hydrogen cyanide, blood agent Patient Care Goals 1. Assure adequate ventilation, oxygenation and correction of hypoperfusion Patient Presentation Cyanide is a colorless, bitter almond smell (genetically only 40% of population can smell) gas or white crystal which binds to the ferric ion in cells, blocking the enzyme cytochrome oxidase, thus preventing the use of oxygen by the cells mitochondria, leading to cellular hypoxia. Depending on its form, cyanide can enter the body through inhalation, ingestion, or absorption through the skin. Non-specific and early signs of cyanide exposure (inhalation, ingestion, or absorption) include the following signs and symptoms: anxiety, vertigo, weakness, headache, tachypnea, nausea, dyspnea, vomiting, and tachycardia 2. The rapidity of onset is related to the severity of exposure (inhalation or ingestion) and may be dramatic with immediate effects that include early hypertension with subsequent hypotension, sudden cardiovascular collapse or seizure/coma, and rapid death Exclusion Criteria No recommendations Patient Management Assessment 1. Assess vital signs including temperature and pulse oximetry (which may not correlate with tissue oxygenation in cyanide/smoke exposure) 4. Monitor patient for signs of hypoxia (pulse oximetry 94%) and respiratory decompensation regardless of pulse oximetry reading 8. Identify the specific agent of exposure, time of ingestion/ inhalation, and quantity/timing of exposure 9. Obtain patient history including cardiovascular history and prescribed medication 10. Perform physical exam Treatment and Interventions There is no widely available, rapid, confirmatory cyanide blood test. Therefore, treatment decisions must be made on the basis of clinical history and signs and symptoms of cyanide intoxication. For the patient with an appropriate history and manifesting one or more significant cyanide exposure signs or symptoms, treat with: 1. Collect a pre-treatment blood sample in the appropriate tube for lactate and cyanide levels 3. Pediatric: Administer hydroxocobalamin 70 mg/kg (reconstitute concentration is 25 mg/mL) 4. If the patient ingests cyanide, it will react with the acids in the stomach generating hydrogen cyanide gas. Be sure to maximize air circulation in closed spaces (ambulance) as the patients gastric contents may contain hydrogen cyanide gases when released with vomiting or belching 3. Hydroxocobalamin is only agent safe for treatment of cyanide poisoning in pregnant patient Notes/Educational Pearls 257 Key Considerations 1. Pulse oximetry accurately reflects serum levels of oxygen but does not accurately reflect tissue oxygen levels therefore should not be relied upon in possible cyanide and/or carbon monoxide toxicity 2. After hydroxocobalamin has been administered, pulse oximetry levels are no longer accurate 3. Be sure to maximize air circulation in closed spaces (ambulance) as the patients gastric contents may contain hydrogen cyanide gases when released with vomiting or belching 4. Hydroxocobalamin and sodium thiosulfate versus sodium nitrite and sodium thiosulfate in the treatment of acute cyanide toxicity in a swine (Sus scrofa) model. Smoke inhalation injury in a pregnant patient: a literature review of the evidence and current best practices in the setting of a classic case. Revision Date September 8, 2017 259 Beta Blocker Poisoning/Overdose Aliases Anti-hypertensive Patient Care Goals 1. Early airway protection is required as patients may have rapid mental status deterioration 3. Assure adequate ventilation, oxygenation and correction of hypoperfusion Patient Presentation Beta blocker or beta adrenergic antagonist medication to reduce the effects of epinephrine/ adrenaline Inclusion Criteria 1. Labetalol hydrochloride (Trandate, Normodyne) Exclusion Criteria No recommendations Patient Management 260 Assessment 1. If risk of rapid decreasing mental status, do not administer oral agent without adequately protecting the airway 2. Check blood glucose level on all patients but especially on pediatric patients as beta blockers can cause hypoglycemia in pediatric population 3. Consider fluid challenge (20 mL/kg) for hypotension with associated bradycardia 5. Consider vasopressors after adequate fluid resuscitation (1-2 liters of crystalloid) for the hypotensive patient [see Shock guideline for pediatric vs. Transcutaneous pacing may not always capture nor correct hypotension when capture is successful 2. Aspiration of activated charcoal can produce a patient where airway management is nearly impossible. Do not administer activated charcoal to any patients that may have a worsening mental status Notes/Educational Pearls Key Considerations 1. Pediatric patient may develop hypoglycemia from beta blocker overdose therefore it is important to perform glucose evaluation b. Glucagon has a side effect of increased vomiting at these doses and ondansetron prophylaxis should be considered 3. Atropine may have little or no effect (likely to be more helpful in mild overdoses) the hypotension and bradycardia may be mutually exclusive and the blood pressure may not respond to correction of bradycardia 4. Certain beta blockers, such as acebutolol and pindolol, may produce tachycardia and hypertension 3. Revision Date September 8, 2017 263 Bites and Envenomation Aliases Stings Patient Care Goals Bites, stings, and envenomations can come from a variety of insects, marine and terrestrial animals. Pain control which also includes limited external interventions to reduce pain Patient Presentation Inclusion Criteria 1. Bites, stings, and envenomations can come from a variety of marine and terrestrial animals and insects causing local or systemic effects 2. Patient physical with special consideration to area of envenomation especially crotalid bite Treatment and Interventions 1. For these envenomations, consider transport to hospital that has access to antivenom, if feasible b. As there is a significant variety and diversity of Jellyfish, it is important to be familiar with the species and the appropriate treatment for your local aquatic creatures ii.
