However erectile dysfunction causes mnemonic buy manforce line, survival with temperatures of 46 ° C were recorded, and fatalities at significantly lower body temperatures have occurred. Heat regulation: the body absorbs heat in the same way as he reveals: conduction, convection, radiation and evaporation. For the function of thermal emission, undisturbed integrity of the skin, sweat glands function and autonomic nervous system is essential. Factors affecting the development of heat disorders: High temperature and humid environment, disturbed evaporation, increased physical activity, age, body weight (thickness), chronic alcoholism and a variety of acute and chronic diseases, medications and drugs. The most serious disorder associated with inadequate thermal regulation is heat stroke. Heat stroke, heat cramps, and heat exhaustion are the three main heat disorders of the human organism. The first type occurs in young people, while the other is not related to physical effort and is common in the elderly, chronically ill and young children. Etiology: Elevated temperature and humidity of the environment, increased body heat production (increased metabolism sepsis, thyrotoxic crisis, increased muscular activity exercise, convulsions, tetanus), decreased possibility of physical cooling, various drugs, and poisoning (cocaine, amphetamines. Clinical signs: Sudden onset, sometimes preceded by headache, dizziness and fatigue Increased heart rate 160-180 / min Blood pressure is often lowered Circulatory collapse, congestive heart failure Rapid breathing Disorientation precedes unconsciousness and convulsions Delirium, confusion, tremors, disturbed speech the feeling of burning Red, dry, hot skin Rapid growth of temperature to 40 41ºC Complications: Heart failure, pulmonary edema Permanent brain damage Renal (25-30%) Damage to the liver, usually transient 75 Damage to the lungs Destruction of muscle mass (rhabdomyolysis) Lethal outcome Prehospital Treatment: the removal of victims from the overheated environment Ceasing all medical interventions that can lead to temperature increase Wrap the victim in wet blankets and allow air circulation (fan) Immersion in water (not ice) Ice cooling the areas around main arteries (femoral, subclavian, carotid artery) In the case of loss of consciousness ensure airways endotracheal tube, laryngeal mask, airway, etc. Heat exhaustion It occurs due to excessive loss of fluids and electrolytes, resulting in hypovolemia and electrolyte disbalance. Occurs very often due to excessive sweating without replacement of water and salt. Clinical presentation: Low blood pressure Poorly palpable pulse the gradual development of malaise and weakness Nausea Excessive sweating Pale, clammy skin Fainting Treatment: Compensation of fluids and salts by the oral route. Heat cramps Heat cramps occur during physical exertion due to excessive intake of water without enough replacement of salt (so-called water intoxication) or due to loss of salt due to strong sweating during physical stress at high temperature (usually above 38 ° C. Take care of small children, the elderly and those with chronic or acute health disorders. Be aware that the lack of a sense of thirst may not be an indicator of good hydration (especially in the elderly. If these disorders are already present, it is necessary to act promptly to avoid further deterioration. Injuries caused by electricity Injuries caused by an electrical current are relatively rare. Some victims of electric shock die at the site of the accident, before it is even possible to provide help, while survivors often have severe injuries that demand quick and adequate treatment and have an uncertain outcome. A third occur in houses and appartments with children being the most frequent victims. It is estimated that a few hundred of these kind of injuries occur in the world every year, with 30% being lethal and 70% leaving severe morbidity in surivors. Injuries caused by electricity are divided into injuries caused by lightning, low and high voltage electricity. Unlike them, injuries caused by high voltage electricity (> 1000 V) along with cardiac arrest, cause very severe damage and destruction of tissue. High voltage electrical current causes the most serious consequences, however, death from low voltage current or so-called "home electricity" also often occur. The factors that determine the nature, seriousness and consequences of electric shock depend on: 1. Path of electric current At current of <1000 V, a direct mechanical contact is required for electric shock to occur. In contrast, with currents that are > 1000 V, the appearance of an electric arc usually causes an electrical impact. Resistance 2 of dry and well-keratinized, intact skin is around 20,000-30,000 Ω /cm, for palmar skin even 2 2 as high as 2. However, if the skin is damaged by abrasion, puncture or cutting wound, resistance can be reduced to 2 200-300 Ω / cm. Unfortunately, in these situations electrical shock, which usually causes less injury, can turn into life-threatening shock. The resistance of the skin can be reduced by prolonged exposure to the current flow, which occurs in alternating current of 50 Hz / sec. This type of power can produce tetanic contractions of skeletal muscles and prevent the release of electricity source and thus lead to prolonged exposure. This phenomenon usually occurs with passing of >14-16 mA current and can lead to dislocation of joints and fractures. With ≤15 mA alternating current it is often possible to release electruical conductor. The above-mentioned phenomena most often happens with alternating currents of > 50 mA, while with direct current this phenomenon is possible at 300-500 mA currents. Severe injuries and destruction of cell membranes of skeletal muscles and nerves occur with currents of > 0. A few seconds of prolonged contact can lead to thermal injuries of subcutaneous and deeper tissues. Since all tissues, regardless of the type, are sensitive to temperature exposure, there is thermal damage of all affected tissues on the path of the electrical current. The spread of electricity also has an impact on the type of possible injury and its 78 consequences. Transthoracic shock (hand-arm) has a higher probability of lethal outcome than vertical (hand-foot) or wide apart (leg-foot. Vertical shock, however, often causes heart damage due to the direct effects of electricity and spasm of the coronary arteries. Injuries from electrocution are the result of two effects: the direct effect of current on the cell membrane and the smooth muscles of the heart and blood vessels and conversion of electrical energy into heat as it passes through different tissues. In the light of this, an injury can be direct (primary) caused by the electricity or heat energy and delayed (secondary) caused by vascular blockages. Fractures and other injuries of musculoskeletal system due to tetanic contractions or falls are frequent. A premature formation of cataract of the eye is possible and even amaurosis blindness. However, if arrhythmias have not developed in the initial stages of injury it seems that such events are rare in the later course. Electrical contact with the head most often causes short-term unconsciousness, with the occurrence of transient convulsions similar to epileptic seizures. Common symptoms are confusion, deafness, amaurosis, headaches and retrograde amnesia. Lightning strike specifities Injuries from lightning strikes are the result of impact caused by an electric arc, rather than by direct contact. An enormous amount of electricity generates a very strong magnetic field around itself, which can induce electrical currents in the nearby body. This current is strong enough to cause heart disturbances and central nervous system damage. The temperature of the electric arc reaches ≤30000 ° K, which induces thermoacustical shock waves, called thunder. Shock waves reach a pressure of 4-5 atmospheres near the arc, while these pressures are much lower already at a distance of 1 m and are at value of 1-2 atm. This event can be very dangerous for people in the vicinity, as a voltage difference of about 1500-2000V between the feet of an individual can occur, with the emergence of the 2-3 A current that lasts for several μsek. Therefore, it is often necessary in trauma patients just to provide respiratory assistance and support. A lightning strike may cause a wide range of neurological injury, which may be the primary, as a result of the direct effect on the brain or secondary, as a result of cardiac arrest and hypoxia. Victims who survive lightning strike or successfully respond to resuscitation have a good prognosis, because subsequent cardiac arrest is not common. Unfortunately, bystanders are afraid to approach the victim, until a couple of minutes pass, fearing that they too may suffer from the "residual current". However, unless the victim is not on an isolated platform, there is no residual electricity after a few milliseconds.

Noordhoff-Chen Technique Noordhoff used a technique based on the Millard?s rotation advancement procedure but modified it in the following manner. The C flap was used either for the columella or the sill depending on the individual patient. Noordhoff addressed the vermillion mismatch (the vermillion on the cleft side is usually fuller than that on the noncleft side. This is in contrast to most other tissues which are all richer on the noncleft side. He retained a V?shaped Unsolved Problems extension from the otherwise discarded part of the cleft side vermillion and inset this into a cut made at the junction Despite the large strides in the correction of the lip and nose, of the wet and dry mucosa (Noordhoff?s red line) on the there remain certain problems that remain uncorrected.

The aim of this extension was to simulate the noncleft philtral column and to avoid a backcut on the lip.

Vestergaard (2002) reported results from a meta-analysis of 25 studies pertaining to smoking history and Graves disease (hyper thyroidism) impotence definition buy manforce overnight delivery, Graves disease with ophthalmopathy, and various forms of hypothyroidism. Current smoking was strongly associated with risk of developing Graves disease (odds ratio 3. One study showed an increasing risk with increasing number of cigarettes per day in current smokers. Some studies were limited to women; in other studies, the number of men was relatively small (20% of the total sample. Nevertheless, there was some indication in the two studies that allowed sex-specific analyses that the association was stronger in women than in men. Stronger associations for never smokers and current smokers were seen with Graves disease with ophthalmopathy (for never smokers, the odds ratio was 4. The only study that presented sex-specific analyses reported a stronger effect in women than in men. Fewer studies are available regarding smoking and hypothyroidism (defined as Hashimoto thyroiditis, clinical hypothyroidism, subclinical hypothyroidism, or autoimmune thyroiditis), and the overall association with hypo thyroidism was weaker (odds ratio around 1. Several prospective studies provided data regarding the risk of developing multiple sclerosis in relation to smoking history in women (Table 12. Villard Mackintosh & Vessey (1993) also found an association with smok ing history and multiple sclerosis in the Oxford Family Planning Association cohort. In a small study using self-reported multiple sclerosis in a population-based study in Norway, the overall asso ciation with ever smokers (risk ratio 1. Two recent reviews have summarized studies of smoking history in relation to risk of developing rheumatoid arthritis (Albano et al. The association with smoking history appears to be stronger in patients positive for rheumatoid factor than in patients negative for rheumatoid factor and stronger in men than in women. There is also some evidence of associations with pack years or smoking duration, but more variable effects have been seen with the amount smoked per day (Albano et al. The severity of rheumatoid arthritis may be increased in smokers, as evidenced by increased disability and risk of extra articular manifestations, including vasculitis and interstitial lung disease, but not of joint swelling (Albano et al. A recent meta-analysis examined the association between smoking and the risk of systemic lupus erythematosus in seven case– control and two cohort studies (Costenbader et al. Larger studies specifically designed to assess sex differences are needed to understand the effect of smoking across the spectrum 144 Chemical/Physical Agents and Autoimmunity of autoimmune diseases. Although a positive correlation between alcohol intake and the degree of liver injury has been reported, there is a high degree of variability in the development and severity of disease between individuals with similar levels of abusive ethanol consumption, and only a small percentage of alcoholic patients develop cirrhosis or hepatitis. Heavy drinkers without significant liver disease had significantly lower titres of IgA antibodies against acetaldehyde modified erythrocyte protein and IgG antibodies against oxidized or malondialdehyde-modified low-density lipoproteins, compared with patients with alcoholic liver disease (Viitala et al. These studies suggest that multiple mechanisms or genetic factors may be involved in the disease process. In support of this, two studies using the National Academy of Sciences – National Research Council twin registry in the United States concluded that there was genetic predisposition to organ-specific complications of alcoholism based on the significant concordance rates in monozygotic twins (Hrubec & Omenn, 1981; Reed et al. Gene polymorphisms encoding for the enzymes responsible for ethanol metabolism, oxidative stress, and proinflammatory/immune responses have been investi gated (Bataller et al. A genetic analysis of individuals participating in a study evaluating liver disease in northern Italy suggested that heavy drinkers with cirrhosis or alcoholic liver disease had a higher frequency (0. A study in alcoholic patients in Japan reported an increase in the frequency of individuals homozygous for the C1 allele in men with alcoholic cirrhosis (Yamauchi et al. In contrast, there was no difference in either C1 or C2 allelic distribution in an earlier study conducted in Caucasian men (Carr et al. Cytokine gene polymorphisms have also been suggested to play a role in the pathogenesis of alcoholic liver disease. The í511 146 Chemical/Physical Agents and Autoimmunity allele 2 was found at a higher frequency in patients with cirrhosis than in heavy drinkers without liver disease. Jarvelainen and colleagues (2001) demonstrated that in Finnish males, expression of one T allele was associated with both alcoholic hepatitis and cirrho sis. There is conflicting evidence as to whether variations in the genes encoding for manganese superoxide dismutase represent a risk factor for alcoholic liver disease (Degoul et al. The data on cytokine and metabolic enzyme gene polymorph isms in the human population as well as experimental studies with ethanol-fed rodents are indicative of the importance of inflamma tion, oxidative stress, and endotoxin in the pathogenesis of alcohol induced liver damage. Chronic ethanol exposure has been associ ated with the formation of alcohol-modified proteins, leading to autoantibody formation and immune-mediated damage to the liver. Circulating antibodies recognizing acetaldehyde–malondialdehyde adducts have been found in Wistar rats fed an ethanol-containing liquid diet (Xu et al. Immunization with acetaldehyde adducts in conjunction with ethanol feeding stimulated ex vivo lymphocyte proliferation in B6 mice, but not in several other strains (Shimada et al. The antibodies generated by these alcohol-modified proteins may also respond to unmodified self-proteins, leading to a breaking of tolerance and autoimmune pathology. Obese strain chickens spon taneously develop a disease very similar to Hashimoto thyroiditis. They were the first model that showed that exposure to iodine affects the course of disease. Depletion of iodine after hatching, achieved by injections of potassium chlorite, reduced thyroid infiltration. In contrast, the onset of spontaneous thyroiditis was hastened by adding sodium iodide to the diet. This effect, however, was reduced by administration of antioxidants, suggesting that reactive oxygen intermediates are one mechanism by which iodine contributes to cell injury. The Biobreeding/Worcester rat has been widely used as a model for studying spontaneous diabetes mellitus, but it also develops autoimmune thyroiditis. Administration of excess iodine accelerates the appearance of the lymphocytic infiltration of the thyroid and the production of thyroid-specific autoantibodies. The incidence of diabetes is very low, but many of the animals develop autoimmune thyroiditis. Iodinated thyroglobulin is more antigenic than the same molecule lacking iodine, suggesting another mechanism by which iodine enhances thyroiditis. Several studies have evaluated the effects of excessive iodine intake in humans, and antithyroid antibodies and iodine-induced hypo and hyperthyroidism have been reported following long-term iodine treatment for endemic goitre (Boyages et al. Although a few epidemiological analyses have been published, they are often confounded by the absence of a clear-cut diagnosis. Clinical outcomes can be the result of immunoallergic, pseudoallergic, or autoimmune-like mechanisms. However, a comprehensive review of adverse autoimmune responses and autoimmune diseases associated with therapeutic agents is beyond the scope of this monograph, and only a few examples will be discussed below. Table 13 provides an abbreviated list of therapeutic drugs that have reportedly been associated with autoimmune reactions. When considering drug-induced autoimmunity, it is important to differentiate two situations. On the other hand, one given agent is associated with only one given type of autoimmune disease. In the latter case, the disease can be organ specific and then closely mimic the spontaneous disease, except that cessation of the offending agent leads to the progressive recovery of clinical and then biological manifestations of the disease. The disease can also be systemic and consists of clinical manifestations and biological/immunological changes markedly different from those of spontaneous diseases. Interestingly, drug-induced systemic autoimmune-like reactions often resemble systemic hypersensitivity reactions, and this further illustrates overlapping mechanisms between immunoallergic and autoimmune-like reactions. Hydralazine inhibits the covalent 150 Chemical/Physical Agents and Autoimmunity binding reaction of the complement protein C4, and susceptibility to hydralazine-induced lupus, as in idiopathic systemic lupus erythema tosus, may depend partly upon genetically determined C4 levels (Sim & Law, 1985; Speirs et al. Adoptive transfer of T cells made autoreactive by treatment with either hydralazine or procainamide causes a lupus like disease (Yung et al. The possibility of a lupus-inducing effect of the drug on T cell development in the thymus has been suggested (Quddus et al. Studies of the specificities of B cells that respond to chroma tin-reactive T cells at the initiation of this autoimmune process demonstrated a rapid and robust expansion of anti-chromatin-secret ing B cells, thus indicating the presence of a normal immune reper toire that includes non-tolerant autoreactive B cells that respond to strong T cell drive and are readily manifested if Fas-mediated activation-induced cell death is inhibited (Ayer et al. Because of a high incidence of adverse events and the strong association with several autoimmune-like phenomena, including myasthenia, pemphigus, and Goodpasture disease, the clinical use is limited. The adverse effects of D-penicillamine in animals are similar to those observed in humans. A study on the effects of D-penicillamine in various strains of mice indicated that D-penicillamine facilitates the induction of autoantibodies in animals with an inherent suscep tibility to autoimmunity (Brik et al. Studies using the popliteal lymph node assay demonstrated that D-penicillamine is capable of inducing an antigen.

A more important clinical outcome would be the effect of the program on reducing the risk of bone fracture. The compliance rate was only 44%, and the 6 months results showed a net benefit of treatment equal to +15. These may be used by patients with mild to severe disabilities such as spinal cord injury, traumatic brain injury, cerebral palsy, muscle dystrophy, or other neuromuscular conditionsthat do not enable the individual to stand independently. They can be used at home, in the workplace, extended care units, assisted living centers, nursing homes, andrehabilitation facilities. Prolonged standing has been investigated over the years for its possible benefits for patients with spinal cord injuries and other disabilities. It is suggested that standing and weight bearing activities may increase bone mineral density and muscle strength, reduce abnormal muscle tone and spasticity, improve circulation, reduce lower limb swelling, improve bowel and bladder function, prevent pressure sores, as well as other potential benefits. Many of these benefits, however, are not supported by good quality evidence (Eng 2001, Bagley 2004, Bernhardt 2012.

Back to Top Date Sent: 3/24/2020 1042 these criteria do not imply or guarantee approval. Criteria | Codes | Revision History Radiosurgery can be defined as the stereotactic (precision) delivery of multiple cross-fired radiation beams to a point or volume within a configured space (Chang 2003. Stereotactic radiosurgery may also be described as a method to destroy targets using single high doses of focused ionizing radiation, administered using stereotactic guidance (Niranjan 2001. It is a combination of minimally invasive technologies administered by a multidisciplinary team consisting of surgeons, oncologists, medical physicists, and engineers. It then evolved to target benign tumors and vascular malformations in surgically inaccessible locations. These indications are continuously expanding with the rapidly evolving technology of radiosurgical systems. Currently it has become an alternative to microsurgery and conventional radiation therapy in the treatment of many lesions in the base of the skull. It is used for vascular, tumor, and functional brain surgery, including arteriovenous malformations, pituitary adenomas, acoustic neuromas, and meningiomas, as well as brain metastases. Radiosurgery was initially limited to the brain because of the requirement of a stereotactic frame attached to the skull to provide a coordinate system for tumor localization. Recent advances however, allow radiosurgical treatment throughout the body without such frames. A variety of methods have been developed to provide a reference system for the localization study to determine the target coordinates, including fixed frame and frameless systems, removable frame systems, and rigid masks. Treatment can be repeated any number of times with equal precision as the target is calculated from the position of gold markers. Isodose distributions, dosage prescription and calculation Setup and quality assurance testing Simulation of prescribed arcs or fixed portals Stereotactic intervention or treatment itself Gamma knife, the prototype of stereotactic radiosurgery was first clinically used in 1967. It developed rapidly from the earlier A-units to B units, and in 1999 to Model C that has a robotic engineering. With the gamma knife, the patient?s head is placed within a large metal collimator consisting of a dome-shaped shell with holes that transmit the radiation to the center point. A stereotactic frame is anchored to the skull with four screws that penetrate the outer table to position the head so that the desired target is at the center of the collimator. The use of the frame limited the use of the gamma knife to head lesions, and to patients who could tolerate the rigid frame fixation. Moreover, the use of fractionated treatments that extended for several days was impractical with the frame fixation (Giller 2005. The CyberKnife is a recently developed frameless stereotactic system that consists of a modified linear accelerator mounted on a robotic arm that moves slowly around the patient. It delivers several beams of radiation at each of many stopping points while minimizing radiation exposure of surrounding tissue (Quinn 2001. Stereotactic precision is achieved without a rigid frame by means of two diagnostic x-ray cameras mounted in the CyberKnife vault and are used to acquire real-time images of the patient?s internal anatomy during treatment. Any patient motion is detected by these images, and the information is used by the robot to compensate and keep the linear acceleration on target. Treatment time ranges from 45-60 minutes and can be given in one fraction, or several fractions with smaller doses given over several days, depending on the condition being treated and the size of the affected area. The use of the CyberKnife for radiosurgery of organs other than the brain is more challenging and requires several technical refinements. When used for spinal lesions for example, it requires the placement of internal small 2-mm stainless steel screws in the spinal lamina adjacent to the target site as ?fiducial markers? (Giller 2005. It is non-invasive, and can treat poor surgical candidates, and tumors inaccessible to surgery, Moreover, it can safely deliver higher doses of radiation than those used in conventional radiotherapy, while sparing the surrounding tissues from the high levels of radiation. It can thus be more effective in treating radioresistant and recurrent tumors and may be used as a boost to conventional radiotherapy. On the other hand, its was reported that its efficacy is lower and risk of complications higher in larger tumors, or those that were previously treated with radiation.

Medical Management Objectives of management are to determine the cause erectile dysfunction herbs order manforce 100mg overnight delivery, to administer therapy for the specific cause (when known), and to detect signs and symptoms of cardiac tamponade. Bed rest is instituted when cardiac output is impaired until fever, chest pain, and friction rub have disappeared. Ask patient to hold breath to help in differentiation: audible on auscultation, synchronous with heartbeat, best heard at the left sternal edge in the fourth intercostal space where the pericardium comes into contact with the left chest wall, scratchy or leathery sound, louder at the end of expiration and may be best heard with patient in sitting position. Diagnosis Nursing Diagnoses • Acute pain related to inflammation of the pericardium P Collaborative Problems/Potential Complications • Pericardial effusion • Cardiac tamponade Planning and Goals the major goals of the patient may include relief of pain and absence of complications. Nursing Interventions Relieving Pain • Advise bed rest or chair rest in a sitting-upright and lean ing-forward position. Perioperative Nursing Management 511 Monitoring and Managing Potential Complications • Observe for pericardial effusion, which can lead to cardiac tamponade: arterial pressure falls; systolic pressure falls while diastolic pressure remains stable; pulse pressure narrows; heart sounds progress from being distant to imperceptible. Reassure patient and continue to assess and record signs and symptoms until physician arrives. Evaluation Expected Patient Outcomes • Is free of pain • Experiences no complications For more information, see Chapters 29 and 30 in Smeltzer, S. Perioperative Nursing Management Preoperative Concerns P Surgery, whether elective or emergency, is a stressful, complex event. Surgery may also be classified according to the degree of urgency involved (emergency, urgent, required, elective, and optional. Whatever its classification, current surgery involves many more ambulatory procedures than ever before and administra tive processes that are new to nursing and other health care staff. However, perioperative nursing concerns still focus on the patient and his or her well-being. Inpatient or outpatient, all surgical procedures require a comprehensive preoperative nursing assessment and interventions to prepare the patient and family before surgery. Informed con sent is required for invasive procedures, such as incision, biopsy, cystoscopy, or paracentesis; procedures requiring sedation and/or anesthesia; nonsurgical procedures that pose more than slight risk to the patient (arteriography); and pro cedures involving radiation. Assessment: Inpatient Surgery • Obtain a health history and perform a physical examination to establish vital signs and a database for future comparisons. Decayed teeth or dental prostheses may become dislodged during intubation for anesthetic delivery and occlude the airway. Assessment: Ambulatory Surgery • Obtain the health history of the ambulatory or same-day surgical patient by telephone interview or at preadmission testing. Ask about recent and past health history, allergies, medications, preoperative preparation, and psychosocial and demographic factors. Also monitor 514 Perioperative Nursing Management elderly patients for dehydration, hypovolemia, and electrolyte imbalances, which can be a significant problem in the elderly population. Nursing Diagnoses • Anxiety related to the surgical experience (anesthesia, pain) and the outcome of surgery • Risk for ineffective therapeutic management regimen related to deficient knowledge of preoperative procedures and pro tocols and postoperative expectations • Fear related to perceived threat of the surgical procedure and separation from support system • Deficient knowledge related to the surgical process Planning and Goals the surgical patients major goals may include relief of pre operative anxiety, adequate nutrition and fluids, optimal res piratory and cardiovascular status, optimal hepatic and renal function, mobility and active body movement, spiritual com fort, and knowledge of preoperative preparations and postop erative expectations. Nursing Interventions Reducing Anxiety and Fear: Providing Psychosocial Support P. Be a good listener, be empathetic, and provide information that helps alleviate concerns. Managing Nutrition and Fluids • Provide nutritional support as ordered to correct any nutri ent deficiency before surgery to provide enough protein for tissue repair. Perioperative Nursing Management 515 • Instruct patient that oral intake of food or water should be withheld 8 to 10 hours before the operation (most com mon), unless physician allows clear fluids up to 3 to 4 hours before surgery. Promoting Optimal Respiratory and Cardiovascular Status • Urge patient to stop smoking 2 months before surgery (or at least 24 hours before. Supporting Hepatic and Renal Function • If patient has a disorder of the liver, carefully assess various liver function tests and acid–base status. Maintain patients body in proper alignment when P patient is placed in any position. Respecting Spiritual and Cultural Beliefs • Help patient obtain spiritual help if he or she requests it; respect and support the beliefs of each patient. Individuals from some cultural groups may not make direct eye contact with others; this lack of eye contact is not avoidance or a lack of interest but a sign of respect. Correct use of communication and interviewing skills can help the nurse acquire invaluable information and insight. Perioperative Nursing Management 517 Providing Preoperative Patient Education • Teach each patient as an individual, with consideration for any unique concerns or learning needs. Include descriptions of the procedures and explanations of the sen sations the patient will experience. Provide a tele phone number for patient to call if questions arise closer to the date of surgery. P Teaching the Ambulatory Surgical Patient • For the same-day or ambulatory surgical patient, teach about discharge and follow-up home care. Education can be pro vided by a videotape, over the telephone, or during a group meeting, night classes, preadmission testing, or the preoper ative interview. Explaining Pain Management • Instruct patient to take medications as frequently as pre scribed during the initial postoperative period for pain relief. Preparing the Bowel for Surgery • If ordered preoperatively, administer or instruct the patient P to take the antibiotic and a cleansing enema or laxative the evening before surgery and repeat it the morning of surgery. Preparing Patient for Surgery • Instruct patient to use detergent–germicide for several days at home (if the surgery is not an emergency. Perioperative Nursing Management 519 • Remove jewelry, including wedding rings (if patient objects, securely fasten the ring with tape. Transporting Patient to Operating Room • Send the completed chart with patient to operating room; attach surgical consent form and all laboratory reports and nurses records, noting any unusual last-minute observations that may have a bearing on the anesthesia or surgery at the front of the chart in a prominent place. Attending to Special Needs of Older Patients • Assess the older patient for dehydration, constipation, and malnutrition; report if present. Attending to the Familys Needs • Assist the family to the surgical waiting room, where the surgeon may meet the family after surgery. P Evaluation Expected Patient Outcomes • Reports decreased fear and anxiety • Voices understanding of surgical intervention Postoperative Nursing Management the postoperative period extends from the time the patient leaves the operating room until the last follow-up visit with the surgeon (as short as a day or two or as long as several months. During the postoperative period, nursing care is directed at reestablishing the patients physiologic equilib rium, alleviating pain, preventing complications, and teach ing the patient self-care. Careful assessment and immediate intervention assist the patient in returning to optimal func tion quickly, safely, and as comfortably as possible. Ongo ing care in the community through home care, telephone Perioperative Nursing Management 521 follow-up, and clinic or office visits promotes an uncompli cated recovery. Postanesthesia care in some hospitals and ambulatory sur gical centers is divided into three phases. The nurse also performs a baseline assessment followed by checking the surgical site for drainage or hemorrhage and connecting all drainage tubes and monitoring lines. After the initial assess ment, the nurse monitors vital signs and assesses the patients general physical status at least every 15 minutes, including assessment of cardiovascular function with the above assess ments. The nurse maintains airway patency and supplemental oxygen; maintains cardiovascular stability with prevention, prompt recognition, and treatment of hemorrhage, hyperten sion, dysrhythmias, hypotension and shock; relieves pain and anxiety; and controls nausea and vomiting. The nurse also notes any pertinent information from the patients history that may be significant (eg, hard of hearing, blind, history of seizures, diabetes, allergies to certain medications or other sub stances. Usually, the nurse makes sure they are transported home safely by a responsible person. Nursing Management in Same-Day Surgery • Inform the patient and caregiver (ie, family member or friend) about expected outcomes and immediate postoperative changes anticipated in the patients capacity for self-care. Provide caregiver Perioperative Nursing Management 523 with verbal and written instructions about what to observe the patient for and about the actions to take if complica tions occur. Follow-up telephone calls from the nurse or surgeon may be used to assess patients progress and to answer any questions. Postoperative Nursing Management in Home Care •The home care nurse assesses the patients physical status (eg, respiratory and cardiovascular status, adequacy of P pain management, surgical incision) and the patients and familys ability to adhere to the recommendations given at the time of discharge. The 524 Perioperative Nursing Management patient and family are instructed about signs and symptoms to report to the surgeon. Perioperative Nursing Management 525 Nursing Interventions Maintaining Patent Airway • Check the orders for and apply supplemental oxygen. Assess respiratory rate and depth, ease of respirations, oxygen sat uration, and breath sounds. Maintain hard rubber or plastic air way in patients mouth or nose until gag reflex resumes.
