In addition treatment zone lasik purchase citalopram 40 mg line, the timing of fever after a procedure can help differentiate potential causes. It is therefore useful to divide the time frame of postprocedure fever into 4 categories: immediate, acute, subacute, and delayed. Fevers that occur in the first 4 days after surgery are less likely to represent infectious complications than are fevers occurring on the fifth and subsequent days (Fig. Fever can also accompany the continuum of systemic inflammatory response, sepsis, severe sepsis, and septic shock (Table 2). In a prospective study of 81 patients with 2 idiopathic postoperative fever, Garibaldi and colleagues found that 80% of those with fever on the first postoperative day had no infection. However, a fever that begins on or after postprocedure day 5 is much more likely to represent a clinically significant infection, so appropriate diagnostics to look for an infectious source may be useful. These tests can include laboratory investigations (blood culture, urine cultures, complete blood counts) and images (plain Fig. Percentage of postoperative fevers occurring on the indicated day following an operative procedure. Lines indicate the percentage of fevers occurring on each day attributable to the cause indicated. These mediators increase capillary permeability and are central elements of 8 the inflammatory response and, thus, healing. The cytokines act directly on the anterior hypothalamus and cause a release of prostaglandins, which mediate the febrile 5 response. The severity of the procedure, in terms of the extent of tissue trauma, can also influence the fever curve. For example, laparoscopic cholecystectomy is associated with fewer episodes 11 of postoperative fever than an open approach. Inflammation secondary to cytokine release is now thought to be the most common cause of immediate postprocedure fever. In the immediate postprocedure period, routine measurement of temperature followed by a detailed laboratory or diagnostic workup is not warranted as long as the patient is hemodynamically stable. Diagnostic tests, such as blood or urine cultures, should not be ordered routinely during this period. A prospective triple-blind study involving 308 consecutive patients found that measuring postoperative body temperature was of limited value in the detection of infection after elective surgery for noninfectious 15 conditions. In the past, atelectasis was thought to be a common cause of postprocedure fever; however, numerous studies have shown that it is not clearly related to fever. Roberts 16 and colleagues evaluated 270 patients who had undergone elective abdominal surgery, and reported the presence of fever in 40%. Atelectasis was associated 15 with neither the presence nor the severity of fever. Vermeulen and colleagues reviewed the records of 284 general surgery patients, who had 2282 temperatures taken. As a predictor of infection, a temperature of 38 C had sensitivity of only 37% and specificity of 80%, a likelihood ratio of a positive test of 1. Other common causes of immediate postprocedural fever include reactions to medication and transfusions, the presence of infection before the procedure, fulminant surgical-site infection, trauma, and adrenal insufficiency. These potentially life-threatening conditions mandate early diagnosis followed by prompt intervention. Presentations might occur particularly early, often within hours to 18 days of the initial procedure. The pathogen can be introduced from hematogenous spread from distant sites of 18,19 infection, minor trauma, or surgical incisions. Fournier gangrene can be caused by colorectal or genitourinary surgical intervention. Other potential sources include 20,21 intramuscular injections, odontogenic infections, or surgery. Commonly cultured organisms include Group A hemolytic streptococci, enterococci, coagulase-negative staphylococci, Staphylococcus aureus, Staphylococcus 18 epidermidis, and clostridial species. In the emergency setting, particularly severe cases can present with signs of systemic inflammation (tachycardia and fever) and even with evidence of end-organ dysfunction (eg, confusion, hypotension). Early consultation with a surgical service is necessary, given that definitive diagnosis and treatment both require operative interventions (debridement, collection samples for pathologic evaluation, and confirmatory diag23 nosis). Prompt surgical consultation, in addition to administration of appropriate antibiotics 25,26 and intravascular volume resuscitation, is imperative. Broad antibiotic coverage should be initiated, covering gram-positive, gram-negative, and anaerobic organisms. Commonly used regimens include a penicillin (vancomycin in penicillin-allergic patients), clindamycin or metronidazole, and an aminoglycoside (or a third-generation 18 cephalosporin or aztreonam). Clinicians caring for these patients must remain watchful for signs of clinical deterioration. Patients who require large amounts of fluid resuscitation might develop pulmonary edema and subsequent respiratory failure requiring ventilatory support. When debridement begins early in the course of illness, defined as less than 24 hours after presen22,27 tation, the morbidity and mortality rates are significantly diminished. In general, fever associated with pulmonary embolism is of low grade (temperature rarely exceeding 38. Septic thrombophlebitis can lead to septic pulmonary emboli, causing a high postprocedural temperature 29 (Fig. Possible pathophysiologic mechanisms of septic pulmonary embolism in the setting of septic thrombophlebitis. The association of septic thrombophlebitis with septic pulmonary embolism in adults. Patients presenting to the emergency department for evaluation of fever and abdominal pain after an intra-abdominal procedure should be presumed to have a surgical complication such as anastomotic leak. Patients can present with symptoms of frank peritonitis, including abdominal pain, nausea, and vomiting. The time lag between surgery and presentation can vary from 1 week to several months. Peritoneal contamination can occur during any interventional, endoscopic, laparoscopic, robotic, or open procedure. The bowel can be injured inadvertently when the peritoneum is entered; for example, with the trocar used during laparoscopy. Patients with prostatic and perinephric infections and abscesses can also present with fever and abdominal pain, but these are retroperitoneal abscesses. After diagnosis, prompt surgical consultation for source control should be obtained. Treatment with broad-spectrum antibiotics should 30 be initiated after specimens for culture are obtained. Alcohol Withdrawal Fever can be an occult sign of withdrawal symptoms in alcoholics. Manifestations of alcohol withdrawal vary from simple tremulousness to the most dramatic and severe form, delirium tremens, with its attendant fever, confusion, hallucinations, agitation, and overactivity of the autonomic nervous system. Patients who are in withdrawal from alcohol can present with simultaneous infections of the respiratory and urinary tracts. Otero31 Antonafi ndcolleagues found no infectious cause of fever in one-third of patients with alcohol withdrawal syndrome. Febrile patients in withdrawal impose an especially difficult scenario on the emergency physician because of the vast array of potential causes of the fever and their typically unreliable and uncooperative manner 32 (Table 4). Patients in alcohol withdrawal require aggressive medical treatment and observation. Benzodiazepines, such as diazepam or lorazepam, should be used liberally for sedation and delirium.

Urinary charts and diaries It is generally thought that collecting information from urinary diaries is not hampered by recall bias medical treatment 80ddb buy citalopram 20 mg fast delivery, as patients report actual data. This was thought to be the result of recall bias present in questionnaire data, but it may also reflect the differences in time frames used for either measure, or the presence of a fluctuation of nocturnal frequency. Frequency volume charts, on which the For example, in people with incontinence volumes voided and the time of micturition are this would include leakage episodes, pad recorded, day and night, for at least 24 hours. Micturition charts have limited value in clinical practice, as the collected data are restricted to frequency only, with no additional information. Bladder diaries are more laborious for patients and will generally be applied where additional information is key to fully understanding the clinical situation, particularly in patients with urgency and incontinence symptoms. Also, in patients with nocturnal or global polyuria, the additional registration of fluid intake may be helpful. Surprisingly, registration of time of awakening and time of going to bed was considered essential only by a small minority, yet it is vital information in the analysis of nocturnal frequency and nocturnal urine production. While a survey revealed numerous urinary diaries in use, none was formally validated. In this phase, patient and clinician opinion on diary format, duration, and content was studied, using interviews and questionnaires. In addition, four draft diary formats were evaluated, and final consensus was reached on the single preferred format. The validity, reliability, and responsiveness of this diary will be further evaluated for contextual validation. Charts of longer duration may increase reliability of nocturnal frequency estimates, but for patients it is more labour intensive and may impair patient compliance with accurate or complete recording. Shorter charts will generally achieve higher compliance, though this is dependent on the individuals completing the charts. Previous analyses on this topic were based on correlation coefficients between consecutive nights completed on the charts (193). This does not, however, take into account that nocturnal frequency may differ between nights, for a variety of reasons. This should include 2 or 3 complete nights, and allow for the need to identify normal variation in nocturnal frequency and voided volumes. Importantly, it must be clear what information should be collected by patients, both in daily practice and for research. Frequency volume charts should include volume of each single void, time of each single void, time of going to bed, and time of rising in the morning. There are several relevant medical disorders; some are known to induce nocturia, while others have an uncertain cause-and-effect relationship. For the former, successful treatment of the causative medical condition should result in improvement of nocturia, but for the latter nocturia might persist. As patients may not be able to report their state of breathing during the night, it is important to ask their bed-sharing partner as well as the patient about breathing interruptions, excessive snoring, or daytime sleepiness. Psychiatric disorders, such as schizophrenia and anxiety disorder, are liable to primary polydipsia, leading to global polyuria and increase of nocturnal urinary frequency (199). These disorders generally accompany diurnal urinary frequency due to global polyuria as well as nocturia, and successful treatment can suppress urination frequency during day and night. Nocturia is one of the most prevalent symptoms in patients with cardiac failure or impaired cardiac function (200). However, there is little evidence that successful treatment for cardiac failure results in improvement of nocturia. It is important to enquire whether sensation of desire to void disturbs sleep or whether nocturnal voiding follows waking for any other cause. Several medications causing sleep disturbance as adverse events, such as central nervous system stimulants and psychotropics, can be theoretically associated with nocturia. However, there are few reports which show a direct association between those drugs and nocturia. Physical examination Clinical examination should consider the possibility for occult neurological disease. Cardiovascular examination is needed, including edema in the lower extremities in the evening (156,202). Abdominal examination can detect an enlarged bladder (post voiding), suggesting chronic urinary retention, or other abdominal masses suggesting reduced functional bladder capacity. The assessed parameters are: minimum, maximum, and average bladder capacity during the daytime and nighttime; urine volume produced during daytime, nighttime, and 24 hours; urinary frequency during daytime and nighttime; and duration of time in bed. Based on these parameters, global or nocturnal polyuria, and global or nocturnal reduced bladder capacity can be judged. Nocturia 159 Transabdominal ultrasonography: Ultrasound can evaluate the size and configuration of the prostate in men, hydronephrosis, thickness of the bladder wall, bladder trabeculations, diverticula, stones, and tumours. These evaluations rarely contribute to the treatment strategy for nocturia except for assessment of the prostate, and may not be essential. Invasive urodynamics: Routine use of invasive urodynamics, such as filling cystometry and pressure flow study, is not recommended. Prostate-specific antigen should be considered in the context of diagnostic recommendations for prostate cancer. Radiological examinations, such as retrograde urethrography, cystography, intravenous pyelography, and abdominal computed tomography, are not routinely used in assessment of nocturia. They should only be used where indicated by the medical context, such as suspected malignant disease or neurogenic bladder dysfunction. It should only be used where indicated by the medical context, such as suspected malignant disease or inflammatory bladder conditions. The Japanese clinical guideline for nocturia (213) recommends the classification of nocturia into three categories: i. In addition, it mentions that categories (1) and (2) are generally treated by primary care physicians or internists but that category (3) will require treatment by a urologist. After 8 weeks of treatment, investigators found that behavioural training reduced nocturia by a median of 0. The multicomponent intervention was individualized for each participant based on his specific combination of risk factors for nocturia. All participants underwent the following behavioural modifications: reduction of caffeine and alcohol, limiting nighttime fluids, and improving sleep hygiene (moderate exercise, paying attention to room light, noise, and temperature). The 56 patients were instructed to do the following: 1) restrict fluid intake; 2) exercise daily; 3) keep warm in bed; and 4) avoid excessive sleep. Finasteride was initially thought to reduce the overall risk for prostate cancer, but it may actually place its users at higher risk of developing high-grade prostate cancer. Possibility for impotence, decreased libido, or ejaculatory dysfunction needs to be considered. Finasteride did not show a significant improvement in nocturia, either in the short term (three trials) or long term (one trial). Finasteride did show an increased risk for ejaculatory disorder, lower libido, and impotence over placebo (219). These drugs may cause orthostatic hypotension, dizziness, or retrograde ejaculation. A prospective, randomized trial of 2,583 men with one or more episodes of nocturia at baseline were treated with doxazosin, finasteride, combination therapy (doxazosin and finasteride), or placebo. Treatment efficacy was measured by self-reported number of nocturia episodes at 1 and 4 years post-treatment. Reductions with combination therapy and with doxazosin were statistically greater than with placebo (p<0.

Reporting and grading of complications in a structured fashion is only one aspect of the quality of outcome reporting 10 medications generic citalopram 40mg on line. Clavien and Dindo proposed a system for grading the severity of postoperative complications [10] that was subsequently revised and validated [11] (Table 2). Acceptable therapeutic regimens are: drugs such as antiemetics, antipyretics, analgesics, diuretics and electrolytes, and physiotherapy. Despite these proposals, no current standard guidelines or criteria exist for reporting surgical complications in the area of urology. It appears important that the urologic community create universally accepted criteria for reporting surgical morbidity and outcomes to establish the efficacy of surgical techniques and improve the quality of patient care [12]. The aim of our work was to review the available reporting systems used for urologic surgical complications; to establish a possible change in attitude towards reporting of complications using standardised systems; to assess systematically the Clavien-Dindo system (currently widely used for the reporting of complications related to urologic surgical interventions); to identify shortcomings in reporting complications, and to present recommendations for the development and implementation of future reporting systems that focus on patientcentred outcomes. The panel did not take intraoperative complications into consideration, which may be addressed in a follow-up project. In the course of 2012 the authors aim to assess the usage and reproducibility of the proposed model for reporting of complications. To establish a possible change in attitude towards reporting of complications related to urologic procedures and assessment of the Clavien-Dindo system in urology, two different strategies were used. Promising articles were identified initially through the tables of contents of the respective journals. All selected papers were full-text retrieved and assessed; papers not reporting complications and reviews were excluded from the analysis. Analysis was done based on a structured form, which was similar for each article and for each journal (Form 1). Data identification for the second objective (systematic assessment of the Clavien-Dindo system currently used for reporting of complications related to urologic surgical interventions) involved a Medline/Embase search using Clavien, urology, and complications as keywords. This search produced 63 eligible papers reporting complications using the Clavien-Dindo system. All selected papers were full-text retrieved for analysis, which was done based on a structured form (Form 2). All papers were evaluated by two authors independently, and in case of disagreement, the paper was presented to all members to reach consensus. This modification was performed to add further precision and to characterise whether an intervention due to the complication led to general anaesthesia, intensive care unit admission, or organ failure, and again, it was based on the type of therapy required to treat the complication. This modified classification, which is known as the Clavien-Dindo system, was validated and tested for interobserver variation in 10 centres around the world [14]. The Clavien-Dindo system is widely used, with an exponential increase in recent years, especially in general surgery but also in urology (see Fig. A few authors have adapted both systems to analyse specific procedures such as living donor liver and kidney transplantation, which has led to confusion [14]. Conceptually, it is very similar to T92 but differs in numbering (for details see Table 1 in Strasberg et al. The Accordion classification was introduced in 2009 and represents a flexible system that can be used in studies of different size and complexity [17] (Table 4). Mild complication Requires only minor invasive procedures that Requires only minor invasive procedures that can be done at the bedside, such as insertion of can be done at the bedside, such as insertion of intravenous lines, urinary catheters and nasogastric intravenous lines, urinary catheters and nasogastric tubes, and drainage of wound infections. Physiotherapy and the following drugs are allowed: Physiotherapy and the following drugs are allowed: antiemetics, antipyretics, analgesics, diuretics and antiemetics, antipyretics, analgesics, diuretics and electrolytes. Moderate complication Requires pharmacological treatment with drugs Requires pharmacological treatment with drugs other than those allowed for minor complications, other than those allowed for minor complications, for example, antibiotics. Severe: invasive procedure without general All complications requiring endoscopic or anaesthesia interventional radiology or re-operation, as well as Requires management by an endoscopic, complications resulting in failure of one or more interventional procedure or re-operation* without organ systems. Severe: operation under general anaesthesia Postoperative death Requires management by an operation under general anaesthesia 5. Death Postoperative death *An example would be wound re-exploration under conscious sedation and/or local anaesthetic. The system is validated, outcome based, and uses data adjusted for patient preoperative risk. It allows comparison of the performance of different hospitals performing major surgery by the ratio of observed to expected (O/E) adverse events. Statistically low (O/E < 1) or high (O/E > 1) outliers are then identified to support continuous quality improvement activities. An adverse event is defined as any new finding or undesirable event that may not be attributed to treatment. Late and acute effects criteria are merged into a single uniform system and applied without a predetermined time-based designation. The unexpected serious and life-threatening (grades 3 and 4) consequences of surgery are the focus of immediate surgical reporting. Interventions such as local treatment or medications may be indicated (they may interfere with specific functions but not enough to impair activities of daily living). There are usually multiple, disruptive symptoms (more serious interventions, including surgery or hospitalisation, may be indicated). Grade 4 Potentially life threatening, catastrophic, disabling, or result in loss of organ, organ function, or limb. The document proposes definitions of specific complications, distinguishing local complications, complications to surrounding organs, and systemic complications. New terms have been proposed and defined in detail such as contraction, prominence, separation, exposure, extrusion, perforation, dehiscence, and sinus tract formation. The classification is based on category, time, and site of complications, with the aim of summarising any of a large range of possible clinical scenarios into a code using as few as three numerals and three (or four) letters. The main goal is to establish common language and to promote a homogeneous registry to improve the quality of pelvic floor surgical procedures using prostheses and grafts. The type of studies reporting complications did not vary between the two time frames selected (1999-2000 vs 2009-2010) (p > 0. However, a shift could be seen in the number of studies using most of the Martin criteria (Fig. A surgical complication in a Western country may not be perceived or subjectively weighted as a surgical complication in rural or less developed countries. As surgical techniques and equipment improve, what were once inevitable negative outcomes may acquire the status of mere surgical complications [2, 5, 7]. Finally, and paradoxically, the higher the expectation of the surgeon and patient, the more potential surgical complications occur [21, 22]. The clinical relevance of reporting surgical complications is primarily related to the fact that the dissemination of technology is very rapid, with current grades of recommendations based on the level of evidence in their corresponding studies. However, in the surgical field, randomised controlled trials with high levels of evidence are uncommon, and this limitation naturally leads to a low number of recommendations. We have to keep in mind that the guidelines can only rely on the surgical evidence. Thus there is a real discrepancy between the reality of daily surgical practice and the relevance of the low-grade recommendations produced in this area. However, the scientific quality of an article is not only related to its level of evidence. The use of more rigorous methodology and the consensus-related complications of surgical techniques will probably improve the quality of the surgical scientific literature. It is likely that this improvement will renew interest in daily clinical practice in the minds of surgeons.

Citalopram 40mg with mastercard

On Romanowsky stained blood smears treatment degenerative disc disease generic citalopram 40mg with visa, it appears as a dark purple spherical granule usually near the periphery of the cell. This can be brought about by an increase in the number of cells replicating, by an increase in the rate of replication, or by prolonged survival of cells. Hypocellularity Decreased cellularity of hematopoietic precursors in the bone marrow. Hypogammaglobulinemi A condition associated with a decrease in a resistance to infection as a result of decreased fi-globulins (immunoglobulins) in the blood. A hypoplastic bone marrow is one in which the proportion of hematopoietic cells to fat cells is decreased. Immune hemolytic An anemia that is caused by premature, immune anemia mediated, destruction of erythrocytes. Consists of two pairs of polypeptide chains: two heavy and two light chains linked together by disulfide bonds. Ineffective erythropoiesisPremature death of erythrocytes in the bone marrow preventing release into circulation. Serologic tests to detect the presence of heterophil antibodies are helpful in differentiating this disease from more serious diseases. Intrinsic factor A glycoprotein secreted by the parietal cells of the stomach that is necessary for binding and absorption of dietary vitamin B12. Jaundice Yellowing of the skin, mucous membranes, and the whites of the eye caused by accumulation of bilirubin. Karyorrhexis Disintegration of the nucleus resulting in the irregular distribution of chromatin fragments within the cytoplasm. Leukemic hiatus A gap in the normal maturation pyramid of cells, with many blasts and some mature forms but very few intermediate maturational stages. Eventually, the immature neoplastic cells fill the bone marrow and spill over into the peripheral blood, producing leukocytosis. There are five types of leukocytes: neutrophils, eosinophils, basophils, lymphocytes, and monocytes. Leukoerythroblastic A condition characterized by the presence of reaction nucleated erythrocytes and a shift-to-the-left in neutrophils in the peripheral blood. Lupus-like anticoagulant A circulating anticoagulant that arises spontaneously in patients with a variety of conditions (originally found in patients with lupus erythematosus) and directed against phospholipid components of the reagents used in laboratory tests for clotting factors. The cell contains terminal deoxynucleotidyltransferase (TdT) but no peroxidase, lipid, or esterase. The nucleus is usually round with condensed chromatin and stains deep, dark purple with romanowsky stains. These cells interact in a series of events that allow the body to attack and eliminate foreign antigen. Reactions are associated with whooping cough, chickenpox, infectious mononucleosis, infectious lymphocytosis, and tuberculosis. Current schemes use a combination of morphologic appearance, phenotype, and genotype. Lysosome Membrane bound sacs in the cytoplasm that contain various hydrolytic enzymes. The cell secretes a variety of products that influence the function of other cells. This parameter will correlate with the extent of chromasia exhibited by the stained cells and is calculated from the hemoglobin and hematocrit. Megakaryocyte A large cell found within the bone marrow characterized by the presence of large or multiple nuclei and abundant cytoplasm. Microenvironment A unique environment in the bone marrow where orderly proliferation and differentiation of precursor cells take place. The monoblast has nonspecific esterase activity that is inhibited by sodium fluoride. Monocyte-macrophage A collection of monocytes and macrophages, system found both intravascularly and extravascularly. Mosaic Occurs in the embryo shortly after fertilization, resulting in congenital aberrations in some cells and some normal cells. In instances where large sequences of nucleotides are missing, the alteration is referred to as a deletion. Myelophthisis Replacement of normal hematopoietic tissue in bone marrow by fibrosis, leukemia, or metastatic cancer cells. Neutrophil A mature white blood cell with a segmented nucleus and granular cytoplasm. Seen in bacterial infections, inflammation, metabolic intoxication, drug intoxication, and tissue necrosis. Normal pooled plasma Platelet-poor plasma collected from at least 20 individuals for coagulation testing. Nuclear-cytoplasmic A condition in which the cellular nucleus matures asynchrony slower than the cytoplasm, suggesting a disturbance in coordination. Nucleus (pl: nuclei) the characteristic structure in the eukaryocytic cell that contains chromosomes and nucleoli. In young, immature hematopoietic cells, the nuclear material is open and dispersed in a lacy pattern. Most oncogenes are altered forms of normal genes that function to regulate cell growth and differentiation. Vitamin K is required for the synthesis of functional prothrombin group coagulation factors. Orthochromatic A nucleated precursor of the erythrocyte that normoblast develops from the polychromatophilic normoblast. Pelger-Huet anomaly An inherited benign condition characterized by the presence of functionally normal neutrophils with a bilobed or round nucleus. Peripheral membrane Protein that is attached to the cell membrane by protein ionic or hydrogen bonds but is outside the lipid framework of the membrane. Plasmacytosis the presence of plasma cells in the peripheral blood or an excess of plasma cells in the bone marrow. Plasminogen A fi-globulin, single-chain glycoprotein that circulates in the blood as a zymogen. Large amounts of plasminogen are absorbed with the fibrin mass during clot formation. Platelets play an important role in primary hemostasis adhering to the ruptured blood vessel wall and aggregating to form a platelet plug over the injured area. Platelet procoagulant the property of platelets that enables activated activity coagulation factors and cofactors to adhere to the platelet surface during the formation of fibrin. Poikilocytosis A term used to describe the presence of variations in the shape of erythrocytes. If stained with new methylene blue, these cells would show reticulum and would be identified as reticulocytes. Polyclonal gammopathy An alteration in immunoglobulin production that is characterized by an increase in immunoglobulins of more than one class. Substituents occupy each of the eight peripheral positions on the four pyrrole rings. Primary fibrinolysis A clinical situation that occurs when there is a release of excessive quantities of plasminogen activators into the blood in the absence of fibrin clot formation. Primary thrombocytosis An increase in platelets that is not secondary to another condition.

Liberal limits may still be used in special circumstances medications 2 cheap citalopram 40 mg fast delivery, such as simultaneous coronary insufficiency, hypoxaemia, acute bleeding and lactate acidosis (Dellinger 2008). Prior to the sepsis recommendation in 2008 (Dellinger 2008), a survey of intensivists in Canada showed that more than 75% already implemented a restrictive policy (Hb < 80 g/L = 5. Level 3 B Zimmerman 2004 C Dellinger 2008, Vincent 2008 Other considerations Micro-circulatory imaging (under the tongue) has thusfar not shown large effects of erythrocyte transfusions in sepsis. The capillary perfusion only appears to improve in patients with abnormal initial values (Sakr 2007). In the case of sepsis, the venous mixed saturation (SvO2) may be used in addition to the Hb in determining the transfusion trigger (Vallet 2007). Sepsis is characterised by severe morbidity with a pathological redistribution of the perfusion and capillary leakage, resulting in abnormal tissue perfusion. As has been demonstrated in studies, the latter can probably be negatively influenced by haemodilution, but conversely this situation is not necessarily positively affected by transfusions. In this setting, it is very important that the actual transfusion-related improvement of a decreased oxygen consumption can be measured. In the case of sepsis, where there is ischaemia and perfusion redistribution at tissue level in one or more organs, the oxygen extraction measured locally in these organs can differ from the systemic value. Despite the lack of convincing scientific research on the effect of a restrictive transfusion policy in patients with sepsis, there appear to be enough indicators that point to the benefits of a more liberal transfusion policy, particularly in the acute unstable phase. In the case of acute anaemia in combination with sepsis the use of the Hb value alone as erythrocyte transfusion trigger is too simple a concept due to the severe morbidity. At this time it is as yet recommended to maintain an Hb value of 6 mmol/L as erythrocyte transfusion trigger following the 4-5-6 rule (see paragraph 5. This is particularly true for patients with symptomatic coronary sclerosis, especially in situations where the oxygen requirement of the heart is increased, such as exertion or in situations in which the availability of oxygen for the heart is decreased, such as tachycardia. In older patients who have recently suffered a myocardial infarction, the mortality increases significantly when the haematocrit value is below 0. In animal experiments, it has been determined that the critical limit for myocardial ischaemia due to anaemia with coronary sclerosis is elevated in comparison to the situation with normal coronary arteries (Wahr 1998, Spahn 1994, Levy 1993, 1992). Careful consideration of the study makes this conclusion less clear (Hajjar 2010). It was demonstrated recently that cardiac surgery patients with a low pre-operative Hb are better able to tolerate a lower post-operative Hb than patients with a high pre-operative Hb. This interesting concept requires further testing, but suggests that it is not 186 Blood Transfusion Guideline, 2011 so much the absolute post-operative Hb value that should determine whether or not to administer transfusions, but that the decrease in Hb during and after the surgery should also be taken into consideration. In older patients who recently suffered from a myocardial infarction, the mortality increases significantly when the haematocrit value is lower than 0. The extent of decrease of the postoperative Hb compared to the pre-operative Hb is possibly associated with a poorer outcome. B Doak 1995 In older patients who have recently suffered a myocardial infarction, the mortality increases significantly when the haematocrit value is lower than Level 3 0. B Carson 1996 Other considerations To summarise, the above-mentioned conclusions were based on old studies in which the erythrocyte components were not yet leukocyte-reduced. Furthermore, the aggregate of studies appears to point to a range for an optimal Hb and Ht: both high and lower Hb and Ht values appear to be associated with higher morbidity. It is particularly difficult to determine the lower limit of these ranges per individual patient. Due to the supposed correlation between mortality and the difference between the post-operative and pre-operative Hb values, the absolute decrease in Hb post-operatively compared to preoperatively should be considered as a transfusion trigger also in patients with cardiovascular disease. A critical limit for anaemia cannot be determined for the individual cardiovascularly compromised patient; an optimal range of Hb values must be taken into consideration. Due to the supposed correlation between mortality and the difference in postoperative versus pre-operative Hb, the absolute Hb decrease post-operative versus pre-operative should also be included in the decision whether or not to transfuse. In healthy volunteers, the cerebral function improveed after transfusion at Hb values between 3. A retrospective study found that the mortality in trauma patients with severe cerebral injury and an Ht < 0. However, Carlson et al demonstrated that patients had better neurological outcomes after longer periods with an Ht < 0. McIntyre found that in a sub-group analysis of the results from a previous randomised trial by Hebert et al (1999), for patients with moderate to severe brain trauma, there was no Blood Transfusion Guideline, 2011 189 189 difference in 30-day mortality and multiple organ failure between a liberal and a restrictive transfusion policy (2006). The brain-tissue oxygenation 1 hour after transfusions was the only primary endpoint for the short term. Transfusions improved the brain tissue oxygenation in 57% of the patients, with the extent of improvement correlating to the Hb increase. Patients with elevated cerebral pressure due to trauma or with a cerebral heamorhage can theoretically experience damage due to elevated cerebral perfusion caused by haemodilution (Hebert 1997). B Weiskopf 2005, 2006 Transfusions for cerebral trauma patients at a transfusion trigger of 8, 9 or 10 g/dL (5. Of continuing and great importance is that low Hb values with haemodilution in healthy volunteers results in decreased ability to react and memory dysfunction (Zygun 2009). It seems likely that particularly the damaged brain can be extra sensitive to an Hb < 6 mmol/L. General anaesthesia results in a lowering of the metabolism, which causes oxygen consumption to decrease by approximately 10%. Local anaesthetics also influence the micro-circulatory compensation as far as anaemia and hypoxia are concerned. Anaesthetics affect thermoregulation, resulting in hypothermia (also see Chapter 8: Blood-saving techniques and medicines, table 8. In patients with acute anaemia under general anaesthesia, there is a far less pronounced increase in heartrate; the compensatory mechanism is increase in stroke volume due to an increase in preload and an increase in oxygen extraction ratio (Ickx 2000). Under these conditions of activated compensatory mechanisms during severe blood loss, one should exercise caution with the combination of strongly negative inotropic anaesthetics or other medications. Animal studies have shown that the use of halothane is associated in a dose-dependent manner with a smaller increase in cardiac output upon haemodilution. With the use of anaesthetics, the Hb could also not be lowered as far with haemodilution, and the oxygen transport became compromised at an earlier stage (Van der Linden 2003). Level 2 A2 Van der Linden 2000 B Van der Linden 1998 C Lugo 1993, Shibutani 1983, Schou 1997, Bissonnette 1994, Mangano 1992 Anaesthetics can have a negative effect on the compensatory mechanisms activated by acute anaemia. Level 2 A2 Van der Linden 2000 B Van der Linden 1998 B/C Ickx 2000, Habler 1998, Trouwborst 1998, Bissonnette 1994, Boyd 1992, Trouwborst 1992, Van Woerkens 1992, Van der Linden 1990 192 Blood Transfusion Guideline, 2011 Other considerations Under anaesthesia, it is hard to estimate whether a transfusion trigger needs to be adjusted up or down. On the one hand the tissue oxygen requirement and capillary bleeding tendency are often influenced favourably under anaesthesia, on the other hand anaesthesia can compromise the haemodynamic compensation for blood loss. With acute anaemia under anaesthesia, one should consider more factors than only a target Hb or Ht. Other parameters that reflect tissue perfusion, such as oxygen delivery and oxygen consumption should preferably be included in the transfusion policy. Research needs to be performed in order to formulate concrete guidelines for this situation. Usually, the oxygen transport capacity is maintained by the various compensatory mechanisms. In addition to pre-existing co-morbidity, the following factors are important post-operatively: Continuing action of hypnotics, sedatives and opioids may either decrease or increase oxygen consumption;some loco-regional techniques inhibit the ability of the sympathetic nervous system to activate the compensatory mechanisms (see paragraph 5. The evaluation of the oxygen status, the filling state and the haematocrit of the patient can be difficult in the immediate post-operative phase due to ongoing blood loss, intercompartmental shifts and dilution due to infusion therapy. In order to detect and treat hypoxia and tissue ischaemia at an early stage, continuous monitoring of the arterial oxygen saturation, circulatory and pulmonary parameters, frequent repeat measurements of Hb or Ht and clinical observation of the patient are essential. Tolerance There are no indications that a low Hb negatively influences wound healing (Bracey 1999). In a number of randomised studies on various forms of surgery and in a number of retrospective studies, it has been shown that a low Hb down to 4. These low values apply to young men with a normal to high-normal body weight; others (the elderly, women and patients with a low body weight) have a greater transfusion need (see table 5. Blood Transfusion Guideline, 2011 193 193 Although a liberal transfusion policy after hip operations in elderly patients did not result in improved rehabilitation, a restrictive policy was associated with more cardiovascular complications and a higher mortality (Foss 2009).
