Preamble Guidelines summarize and evaluate all available evidence, at the time of the writing process, on a particular issue with the aim of assisting physicians in selecting the best management strategies for an individual patient, with a given condition, taking into account the impact on outcome, as well as the risk benefit ratio of particular diagnostic or therapeutic means. Guidelines and recommendations should help the physicians to make decisions in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible physician(s). Because of the impact on clinical practice, quality criteria for the development of guidelines have been established in order to make all decisions transparent to the user. A critical evaluation of diagnostic and therapeutic procedures was performed including assessment of the riskbenefit ratio. Estimates of expected health outcomes for larger populations were included, where data exist. The level of evidence and the strength of recommendation of particular treatment options were weighed and graded according to pre-defined scales, as outlined in Tables 1 and 2. The experts of the writing and reviewing panels filled in declarations of interest forms which might be perceived as real or potential sources of conflicts of interest. The Committee is also responsible for the endorsement process of these Guidelines. After appropriate revisions it is approved by all the experts involved in the Task Force. The task of developing Guidelines covers not only the integration of the most recent research, but also the creation of educational tools and implementation programmes for the recommendations. To implement the guidelines, condensed pocket guidelines versions, summary slides, booklets with essential messages, and an electronic version for digital applications (smartphones, etc. Implementation Table 1 Classes of recommendation Classes of recommendations Class I Definition Evidence and/or general agreement that a given treatment or procedure is beneficial, useful, effective.

Reverse mirror reading requires an individual to arteria facialis cheap lisinopril master card trace a maze while looking at it through a mirror blood pressure numbers for seniors buy 17.5 mg lisinopril amex. Perceptually blood pressure range buy genuine lisinopril on line, amnesiacs also show normal adaptive behavior when wearing visual prisms. Because prisms distort visual input, simple acts such as reaching for an object are misdirected at first. The visual motor system must quickly learn to "retune" the system so that it again correctly targets reaching according to the new visual information. Interestingly, amnesiacs can do this performance learning and adaptation despite severe declarative amnesia. However, amnesiacs do not show normal nondeclarative skill learning for all tasks. For example, investigations (Gabrieli, Keane, & Corkin, 1987; Xu & Corkin, 2001) of H. The patients were required to press one of four keys when illumination occurred above a key. The patient groups were not aware that there was a repeating sequence of illumination; yet, across learning trials, the patients with amnesia demonstrated improved performance as evidenced in decreased key press reaction times. Functional imaging studies have confirmed that serial reaction-time skill learning is supported by the striatal region and circuitry. Other regions that exhibit learning-related changes during serial reaction-time skill learning primarily involve the neocortex (primary motor, supplementary motor, premotor, parietal and occipital cortices). These changes suggest that serial reaction-time learning involves changes in perceptual and motor areas supporting visually guided movements (Schacter & Curran, 2000). For example, in the word stem completion priming paradigm, a list of words is first presented (for example, church, parachute, clarinet, and so on). Examiners then give patients three-letter word stems (for example, chu, par, cla ) and ask them to make a word by completing the stems. Perceptual priming also appears in the quicker recognition of fragmented objects (such as those presented in Chapter 8 for testing apperceptive agnosics) or of words (see Figure 9. Perceptually based implicit priming is associated with decreased activity of the posterior neocortex. It has been theorized that the decreased activation of the posterior neocortex reflects a reduction in neural resources needed to process the content when it recurs, because a visual trace remains from the original presentation of the material (Squire & Knowlton, 2000). Recognition memory appears to involve the encoding of phonetic or semantic declarative information, whereas priming depends on the visual features of the presented content. In addition, different brain systems are believed to support the two types of memory. An example of recognition memory would be asking a person to memorize a list of words, and then presenting the words, at a later time, randomly interspersed with other nonpresented words. Identification of the words originally learned provides a measure of recognition memory. Case studies show that patients with lesions of the visual extrastriate region demonstrate deficits of visual perceptual priming but intact recognition memory. The individuals are then informed that the consonant strings were generated in accordance with a set of rules. After this explanation, they are exposed to a list of grammatical and nongrammatical consonant strings and are asked to judge which strings were formed by the same set of rules. Patients with amnesia perform the task as well as healthy participants, even though they have no memory for the consonant strings used during the training. Research suggests that the posterior neocortex may support the performance of artificial grammar tasks, leading some investigators to pose that this type of learning may reflect priming or perceptual processing (Schacter & Curran, 2000; Squire & Knowlton, 2000). The simplest form of nondeclarative memory involves classic or associative learning. This type of memory is evolutionarily much older and generally operates on the basis of learned associations. Researchers can demonstrate that even animals whose hippocampus has been removed can learn simple stimulusresponse associations. For example, planaria can learn a lightshock pairing and recoil from the light when they subsequently encounter it alone. This suggests that some basic and primitive aspects of associative conditioning are operating. But, amnesiacs who have been pin-pricked by their doctor while shaking hands during their first meeting, often withdraw their hand when the doctor extends his or her hand at a second meeting even though they may not consciously recall the association between shaking hands with the doctor and being pricked by a pin. Whether the same brain circuitry governs all aspects of nondeclarative memory is not fully understood. However, evidence suggests that structures supporting nondeclarative memory are probably evolutionarily and ontologically older and more primitive. We stated earlier that even simple animals without a hippocampal system can learn associative information. Infants between 2 and 5 months of age quickly learn that they can kick to move a mobile attached to one leg (Rovee-Collier, 1993). Many brain structures involved in movement, including the cerebellum, the basal ganglia, and the motor strip, are implicated in motor learning. The cerebellum aids in sequential motor learning such as the steps required in learning the piano. The basal ganglion is an important brain circuit responsible for perceptual-motor learning and adaptation (Figure 9. We discuss this circuit in Premotor cortex Basal ganglia Thalamus Parietal Frontal a. Temporal Occipital Neocortex Premotor cortex Basal ganglia Ventral thalamus Substantia nigra b. Specifically, this circuit includes the caudate nucleus, putamen, and globus pallidus. The nuclei of the striatum (caudate and putamen) receive projected information from cortical sensory areas. From the striatum, information then funnels through the globus pallidus, and then on to the thalamus, where it projects to the premotor and prefrontal areas (see Figure 7. The atrophic imaging change appears at the onset of the choreiform movement disorder. This double dissociation in functioning prompted the initial suggestion for separate cortical and subcortical memory structures. Since that time, animal studies and imaging studies with healthy participants performing motor learning tasks have added evidence for the role of the basal ganglia in implicit memory. Out of this ante-chamber the ideas most nearly allied to those in the presence chamber appear to be summoned in a mechanically logical way, and to have their turn of audience.

The biopsy shows a monomorphic intradermal neoplasm composed of cells with round nuclei, vesicular chromatin, and focally prominent nucleoli, arranged in sheets. Although the acral location is good for epithelioid sarcoma, epithelioid sarcoma tends to show a less monomorphic population of tumor cells, with more abundant eosinophilic cytoplasm. Primary cutaneous Ewing sarcoma: a systematic review focused on treatment and outcome. Ruptured epidermoid cyst (Incorrect) the well-circumscribed nodular pattern may raise the possibility of a ruptured cyst. Ruptured dermoid cyst (Incorrect) the eyebrow location would raise the possibility of a dermoid cyst. Reaction to hyaluronic acid (Incorrect) the histologic appearance of hyaluronic acid consists of extracellular basophilic amorphous material. Reaction to poly-L-lactic acid (Correct) Foreign body granulomatous inflammatory infiltrate with numerous multinucleated giant cells around translucent particles of different sizes (oval, fusiform or spiky shape) and frequent asteroid bodies. Reaction to calcium hydroxylapatite (Incorrect) the histologic appearance of calcium hydroxylapatite consists of bluish-gray, round to oval microspheres. Question Which of the following injectable soft tissue fillers is birefringent in polarized light examination? Polymethyl-methacrylate microspheres (Incorrect) Non-birefringent in polarized light E. Nodules at the injection sites, which are palpable but generally not visible, may occur in up to 30% - 40% of patients, and without treatment tend to persist for months or years. Histopathologic Features: Granulomatous adverse reactions at the sites of injection of poly-L-lactic acid may occur and reveal a foreign body granulomatous inflammatory infiltrate with numerous multinucleated giant cells around translucent particles of different sizes, most of them demonstrating an oval, fusiform or spiky shape (shorter and wider than cholesterol clefts). Asteroid bodies are frequently seen within the cytoplasm of multinucleated giant cells. Hyaluronic acid plus dextranomer microparticles (Matridex): suppurative granulomatous inflammatory infiltrate surrounding extracellular basophilic amorphous material (hyaluronic acid) and spherical dark bluish particles (dextranomer microparticles). Calcium hydroxylapatite (Radiesse, Radiance): generally does not induce a foreign body reaction; however, granulomatous inflammation may occasionally occur. The microspheres of calcium hydroxylapatite are bluish-gray in color, 25 to 40 um in size, and round to oval in shape. Polymethyl-methacrylate microspheres in bovine collagen (Artecoll, Arteplast, Artefill): nodular or diffuse granulomatous infiltrate surrounding round, sharply circumscribed, translucent, nonbirefringent vacuoles of similar shape and size that resemble normal adipocytes within a sclerotic stroma. Hydroxyethylmethacrylate/ethylmethacrylate fragments in hyaluronic acid (Dermalive, Dermadeep): nodular granulomatous infiltrates of macrophages and multinucleated giant cells with numerous pseudocystic structures of different sizes and shapes containing polygonal, pink, translucent, non-birefringent foreign bodies. Bovine collagen (Zyderm, Zyplast): bovine collagen differs from native human collagen in being acellular, thicker and more eosinophilic. Polyacrylamide hydrogel (Aquamid, Interfall, OutLine, Royamid, Formacryl, Argiform, Amazingel, Bio-Formacryl, Kosmogel): granulomatous inflammatory infiltrate composed of macrophages, foreign body giant cells, lymphocytes and red cells surrounding basophilic multivacuolated non-birefringent material. Polyalkylimide gel (Bio-Alcamid): basophilic amorphous material with granular appearance surrounded by sparse epithelioid histiocytes, foreign body multinucleated giant cells, neutrophils, and red cells. Silicone: variable histopathologic findings depending on the form of the injected silicone. Solid elastomer silicone induces an exuberant foreign body granulomatous reaction, while silicone oil and gel induce a sparser inflammatory response. Silicone particles appear as groups of round non-birefringent empty vacuoles of different sizes between collagen bundles or within macrophages. Polymerized silicone elastomer dispersed in polyvinylpyrrolidone (Bioplastique) reactions show granulomas with irregularly shaped cystic spaces containing translucent, jagged, popcorn-like, non-birefringent particles of varying size dispersed in a sclerotic stroma surrounded by abundant multinucleated foreign body giant cells, some of them containing asteroid bodies. Human histology and persistence of various injectable filler substances for soft tissue augmentation. Adverse cutaneous reactions to soft tissue fillers-a review of the histological features. The tumor cells exhibit increased cytoplasm and nuclear grooves with smooth chromatin and associated eosinophilic inflammation. The characteristic granular cytoplasm of the tumor cells and overlying pseudoepitheliomatous hyperplasia are not evident. The tumor cells do not exhibit the classic nested morphology of a melanocytic nevus and lacks features of maturation, pigment. The lesions lacks features of immature vascular formation with red blood cell extravasation at the periphery or an infiltrative pattern of growth by the tumor cells. Question 98 the special stain likely to be most helpful in confirming the diagnosis is: A. Since the cells are positive for S100, this lesion is unlikely to represent a mycobacterial infection. Given the negativity for numerous other melanocytic markers, an additional melanocytic marker is unlikely to be of high yield. Together with the morphology and the immunophenotypic findings already reported, this would confirm the diagnosis of Langerhans Cell Histiocytosis. Langerhans cells contain increased pale eosinophilic cytoplasm with enlarged, folded or grooved nuclei (often "kidney shaped") with smooth chromatin and lacking conspicuous nucleoli. Prominent Langerhans cell migration in the arthropod bite reactions, simulating Langerhans cell histiocytosis. Myeloid leukemia cutis (Incorrect) the immunophenotype seen here is B-cell, not myeloid. Mantle cell lymphoma (Correct) the morphologic features and the immunophenotype seen here are consistent with mantle cell lymphoma. Clinical Features Mantle cell lymphoma is a B-cell lymphoma generally composed of monomorphic small to medium-sized lymphocytes with irregular nuclear contours and expressing Cyclin D1. Other frequent sites are the spleen, gastrointestinal tract, and bone marrow (with or without peripheral blood involvement). Cutaneous lesions are uncommon but may represent the first manifestation of mantle cell lymphoma. Neoplastic large/transformed cells resembling centroblasts, immunoblasts or paraimmunoblasts are not seen. There is a spectrum of morphologic variants, including small cell (small round lymphocytes mimicking small lymphocytic lymphoma), blastoid (cells resembling lymphoblasts with dispersed chromatin and high mitotic rate) and pleomorphic (larger pleomorphic cells with oval to irregular nuclear contours and often prominent nucleoli). Mantle cell lymphoma involving skin: cutaneous lesions may be the first manifestation of disease and tumors often have blastoid cytologic features. The vast majority of the plasma cells are immunoreactive with lambda immunoglobulin light chain stain. A systemic work-up (including bone marrow examination, imaging studies, and serum/urine protein electrophoresis) is negative. Secondary syphilis (Incorrect) While syphilis is often associated with plasma cell-rich infiltrates, the plasma cells should be polytypic.

Mayo P, Beaulieu Y, Doelken P, et al: American College of Chest Physicians/La Societe de Reanimation de Langue Francaise Statement on Competence in Critical Care Ultrasonography. Neri L; Storti E; Lichtenstein D: Toward an ultrasound curriculum for critical care medicine. Anesthesiology 2012; 117:801-809 Free fluid in abdomen is shown in a patient who was taken to the operating room for hypotension. This was a trauma patient who had no other obvious cause of bleeding and was found to have a liver laceration. The most important quality of bedside/ portable/point of care ultrasound is reproducibility. Real-time diagnosis based-on images obtained still require proper clinical context in order to make expedient and correct interventions without delay. Improvements in image quality and acquisition allows further developments for new applications in ultrasonography. Volpicelli G, et al: International evidence-based recommendations for point-of-care lung ultrasound. This involves a multistep process in which tests are ordered, samples are drawn, labeled, and transported to the laboratory. There, they are analyzed and the results then communicated back to the requesting unit/physician (Figure 1). He was admitted to the hospital two days prior for diverticulitis and has a medical history significant for insulin dependent diabetes, coronary artery disease, and prior stroke. In addition, time to treatment was reduced for patients with conditions where timing was considered to be critical. Rapid turnaround in laboratory tests is required for prompt diagnosis, early therapy, and changes in management. An example is the use of fiberoptic pulmonary artery catheters to continuously measure mixed venous oxygen saturation (SvO2). Other in vivo tests include subcutaneous realtime glucose monitoring or measurement of arterial blood gas via intra-arterial sensors. However, glucose values obtained with a point-of-care device can differ significantly from those obtained by laboratory analysis. In addition, values drawn from a central venous catheter can differ from those obtained from a finger stick. Life threatening changes in these parameters can occur suddenly and rapid results are often key to diagnosis and treatment. When a microanalyzer was implemented to analyze electrolytes and blood gases on trauma patients in the emergency room, the reported laboratory values were accurate and fast and provided more information for evaluation and patient management. Timely evaluation of coagulation status can facilitate appropriate use of blood products and related medications. A whole blood sample is added to an activator (diatomaceous earth or clay) and the time to clot formation is measured. It is often used in the operating room when monitoring the effect of heparin or direct thrombin inhibitors such as argatroban, bivalirudin, and lepirudin. It measures the movement of a pin placed in a rotating cup filled with whole blood mixed with kaolin. As clot forms, the freely hanging pin becomes bound to the rotating cup and movement of the pin is recorded to produce a graph with parameters (Figure 2). Some devices provide standard complete blood counts, including platelet count and evaluation of platelet function such as aggregation and inhibition. Ultrasound Ultrasound is a point of care technology that is rapidly becoming 96 an invaluable tool in the diagnosis and management of a variety of life threatening conditions such as pneumothorax, cardiac tamponade, acute heart failure, and severe hypovolemia (12). The point of care ultrasound has been described as "the stethoscope of the future.

Cytotoxic edema, which occurs between 2-5 days post ischemia, can cause significant brain swelling and possibly herniation. The decision was made to take him to interventional radiology for intra-arterial thrombolysis. Since he is at a high risk for malignant cerebral edema, a neurosurgery consultation is placed for consideration of decompression with hemi craniectomy. The adult human brain weighs approximately 1350 grams and receives between 12-18% of the total cardiac output. In an average sized adult with a cardiac output of 5 liters per minute, this is about 750 ml of blood per minute circulating through the four main cerebral arteries to the cranial vault. If flow decreases < 20 ml/100 grams/minute, cells will shift to anaerobic metabolism and pyruvate production, which leads to acidosis and cell death. The fluid flows from the lateral ventricles through the two foramens of Monroe into the third ventricle; through the cerebral aqueduct into the fourth ventricle; and finally through the foramen of Magendie and two foramens of Luschka. Two vertebral arteries merge to form the basilar artery and its branches, forming the posterior circulation. Two internal carotid arteries take a tortuous course through the bony skull and divide into the middle cerebral and anterior cerebral arteries, forming the anterior circulation. At this level there is intense vasoconstriction that may lead to cerebral ischemia.

Not recommended for patients with poor adherence to therapy or those with poorly-controlled asthma. May reduce risk for future development of asthma, and treatment of allergic rhinitis may improve asthma control. Mast cell stabilizers: Cromolyn sodium (Opticrom), lodoxamidetromethamine (Alomide), nedocromil (Alocril), pemirolast (Alamast) b. Often a combination of several syndromes; symptoms can occur within minutes to hours of ingesting food. Diagnosis requires both sensitization (demonstration of allergenspecific IgE) and clinical symptoms after exposure to allergens. Atopic dermatitis/eczema: (1) Food allergy is more common in patients with atopic dermatitis. Oral allergy syndrome: (1) Pollen-associated food allergy caused by cross-reactivity of antibodies to pollens. Allergic eosinophilic gastroenteritis, esophagitis: (1) May cause abdominal pain, diarrhea, vomiting, dysphagia, early satiety (2) May be confused with reflux (3) Characterized by eosinophilic infiltration of digestive tract; 50%60% of patients with elevated serum IgE levels (4) Dietary therapy can be effective; often guided by allergy testing (5) In some cases, topical steroids, or a combination of dietary avoidance and topical steroids, may be needed for effective control c. Food-induced enterocolitis: (1) Presents in infancy (2) Vomiting and diarrhea (may contain blood); when severe, may lead to lethargy, dehydration, hypotension, acidosis (3) Most commonly associated with milk and soy but may occur with a wide variety of foods. Infantile proctocolitis: (1) Confined to distal colon and can present with diarrhea or blood-streaked and mucous stools (2) Symptoms usually resolve within 72 hours of stopping offending agent; rarely leads to anemia C. Mainstays of diagnosis, but skin and/or IgE testing needed to identify trigger foods 2. Skin prick test has poor positive predictive value but very good negative predictive value Chapter 15 Immunology and Allergy 399 Confirm history of food allergy to specific food(s) Does process seem IgE-mediated? No Elimination diet Improvement Yes Skin testing Positive No improvement Negative Stop and re-evaluate History of anaphylaxis? Similar to skin tests, it has poor positive predictive value, excellent negative predictive value b. Levels above a certain range (different for different antigens) have increasing positive predictive value c. Component testing (measuring IgE to specific food proteins rather than crude extracts) may improve diagnostic accuracy for peanut, possibly, other foods. Can verify clinical reactivity to a specific food allergen or document that a food allergy has been outgrown b. Must be performed under close medical supervision with emergency medications readily available c. Open challenges are most often used, but most accurate when double-blinded using graded doses of disguised food 5. Food intolerance: Nonimmunologic, based on toxins or other properties of foods leading to adverse effects 2. Allergen avoidance is the most important intervention for all types of food allergy. Anaphylaxis: Epinephrine, all at-risk patients should have an epinephrine auto-injector 5.

Conclusions Available data suggest that critically ill and injured patients can be transported safely in a variety of transport environments with proper understanding and mitigation of risk. However, the transport environment remains associated with an increased risk for adverse events. Transfer of an unstable patient with urosepsis who is unable to pay for treatment in the emergency department at the referring facility b. Transfer of a patient with an acute coronary syndrome from a regional cardiac center to a nearby community hospital d. Transfer of a trauma patient who has tachycardia and orthostatic hypotension upon arrival to the emergency department of a community hospital 2. Transport ventilators are capable of maintaining the same ventilator parameters as critical care ventilators b. Transport ventilators use special batteries that do not require frequent recharging 46 c. Transport ventilators may prevent harmful hypoventilation or hyperventilation of patients with increased intracranial pressure 3. Patient movement is associated with an increased risk of ventilator associated pneumonia d. Adverse events are rare during intrahospital patient transport 47 Section 6 Cardiopulmonary Resuscitation Key Points: · the 5 criteria defining high quality chest compressions are: adequate rate (100 120/min), adequate depth (2-2. The patient is brought emergently to cardiac catheterization, but no intervention is done due to lack of a defined culprit lesion. Upon rewarming, the patient opens eyes spontaneously, follows commands in all four extremities, and is able to be extubated. The five criteria defining high quality chest compressions are: adequate rate (100 - 120/min), adequate depth (2 - 2. The importance of minimizing interruptions to chest compressions is another emphasis of the 2015 recommendations. Updated guidelines further define and emphasize the importance of high quality chest compressions. Nielsen N, et al: Targeted temperature management at 33°C versus 36°C after cardiac arrest. Epinephrine 1 mg 52 Section 7 Ethics and Organ Donation Key Points: · the four principles of medical ethics are autonomy, beneficence, nonmaleficence, and justice. A family meeting occurs with physicians, nurses, and a social worker to discuss prognosis and goals of care with his wife and daughters. After being updated regarding his overall clinical picture and poor prognosis, his wife makes the difficult decision to withdraw ventilator support, stating that her husband would never have wanted to be kept alive with a ventilator if there was little chance for meaningful recovery. It is determined that the patient can be clinically diagnosed as having "brain death. Ethical issues occur frequently in the intensive care unit, and decision-making during critical illness or at the end of life may pose some of the most complex 53 ethical challenges encountered in medicine. There are four core principles in medical ethics that provide a framework to guide such decision-making: autonomy, beneficence, non-maleficence, and justice. Autonomy is the concept that the patient has the right to self-determination: to choose or refuse treatments when offered. Beneficence is the tenet that providers should always deliver care which is in the best interest of the patient, while nonmaleficence refers to refraining from care that causes harm to the patient. The principle of justice refers to the fair and equitable allocation of resources amongst patients. The concept of medical futility can be an important yet difficult premise to establish when dealing with patients having progressive disease. In such circumstances, the determination of an appropriate treatment and care plan is multifaceted. In assessing individual patients, the provider will want to make sure that the patient can understand the outlined treatment and comprehend the risks and benefits of accepting or rejecting options. These documents - such as a health care proxy, durable power of attorney for health care, and other advance care directives - may give insight to those individuals and the health care team as to what the patient would or would not have wanted. Advance directives include documents like living wills or instructional directives, which can include desire for or against certain interventions. If the patient is deemed not capable of making his or her own decisions and has not previously designated a particular individual for that role, a surrogate decision maker can be identified to be their "voice. Alternatively, once a surrogate decision maker is appointed, conflict may arise when a treatment plan has been decided. Withdrawal of Life Support Whether or not an advance directive is present, a patient or their surrogate decision maker has the right to change their preferences regarding care treatments as their clinical condition changes. Included in this are decisions to withhold and withdraw specific medical interventions. It is important to keep in mind that withdrawal of support is not withdrawal of care. There are often ethical misconceptions about withdrawing or withholding medical support, which include concerns about patient abandonment, violation of the principle of beneficence, or the use of sedatives hastening death. The Principle of Double Effect states that an act which may ultimately have undesirable side effects is permissible if the intended outcome is in itself good, is not intended to do harm, and outweighs the bad. With few exceptions, the majority of states in the United States do not permit physicianassisted suicide. In the United States, there is no ethical difference between withholding or withdrawing treatment. It may, however, be hard emotionally for families to withdraw life support once it has been initiated. Over the years, there have been several public court cases about withdrawal of life-sustaining support such as Karen Ann Quinlan in the 1970s (involving withdrawal of ventilator support) and more recently Terri Schiavo in 2005 (involving withdrawal of nutritional support). These cases among others have set precedents on current ethical standards in clinical practice. Prior to life sustaining therapy being withdrawn, there are several considerations that should be addressed. The family needs to be informed about what to expect, whether that be irregular 55 breathing if taken off of the ventilator or a slower decline if nutritional support is withdrawn. It should be emphasized that pain relief will be a primary consideration and a plan for narcotics or sedative/anxiolytic agents should be available. In many institutions, there are protocols established to guide withdrawal of life support in the most humane way. Ultimately, the amount of time until death after support is withdrawn is difficult to predict. For example, the time to death after withdrawal of mechanical ventilation usually occurs within 24 hours but can range from minutes to days or even longer.
