Sinusitis should be considered in patients with nasotracheal or nasogastric tubes- which block the sinus ostia medications for gout buy septra 480 mg cheap, thus predisposing to infection medicine website buy 480mg septra with amex. Careful auscultatory examination should be performed to look for new pulmonary findings that may indicate a nosocomial pneumonia or a new or changing murmur that may indicate endocarditis medicine 72 order genuine septra on-line. Abdominal examination should be performed to assess the presence or absence of bowel sounds and any focal tenderness or masses symptoms 4dpiui buy cheap septra. All intravascular catheter sites should be scrutinized for signs of inflammation at the catheter exit site or along the subcutaneous tunnel. Laboratory and Imaging Studies-Laboratory evaluation should include a complete blood count, routine chemistries with liver enzymes, and urinalysis. Other evaluations should be directed by the results of the history and physical examination. A chest radiograph and sputum sample for culture should be obtained when nosocomial pneumonia is suspected. Any wounds that appear infected should be debrided, with cultures performed on any purulent material. Risk factors include altered mental status, lung disease, endotracheal tube, or tracheostomy. General Considerations It is estimated that at least 5% of hospitalized patients will develop a nosocomial infection. Pneumonia is the second most common nosocomial infection after urinary tract infection and is the leading cause of death owing to hospitalacquired infection. Pathophysiology Pneumonia develops from one of three mechanisms: (1) inhalation of an aerosol containing infectious microorganisms, (2) hematogenous seeding of microorganisms in the lung, or (3) aspiration of oropharyngeal flora. Contaminated respiratory equipment has been recognized as a source of infected aerosols and a cause of gramnegative bacillary necrotizing pneumonia. Studies have identified a number of risk factors in the development of nosocomial pneumonia. Symptoms and Signs-Patients with suspected nosocomial pneumonia should undergo prompt assessment prior to initiation of therapy. The clinical features of pneumonia in hospitalized patients are subtle and variable, and in some cases, there may be no symptoms or examination findings. Use of clinical and radiographic features alone to diagnose nosocomial pneumonia will lead to the misclassification of many disorders as nosocomial pneumonia. Some diagnostic clues include altered mental status, fever, tachypnea, tachycardia, and abnormal breath sounds. Physical findings commonly include crackles or rales rather than evidence of lung consolidation. Wheezing may be present, and localized wheezing may suggest aspiration of a foreign body. The presence of preexisting abnormal lung findings may make the diagnosis difficult. Patients with a tracheostomy or endotracheal tube may first manifest a lower respiratory tract infection by a change in gross appearance of the respiratory secretions or an increase in oxygen requirement. The physician should query the respiratory therapist or nurse regarding changes in quantity and appearance of these secretions. The development of purulent sputum or an increase in the quantity of secretions suggests heavy bacterial colonization or infection, often prior to the development of a radiographic infiltrate. It is clear that endotracheal aspirates alone are often inaccurate in diagnosing the etiologic agent of a nosocomial pneumonia. Quantitative endotracheal aspirates, a protected specimen brush, or bronchoalveolar lavage often will provide more useful information. However, most diagnostic modalities for nosocomial pneumonia are neither sensitive nor specific. Respiratory cultures obtained by any means must be interpreted with caution because the airways of hospitalized patients are almost always colonized with various potentially pathogenic bacteria. A Gram stain of the sputum may help to identify the etiologic agent and suggest appropriate empirical therapy. A sputum Gram stain that reveals 10 or fewer squamous epithelial cells and more than 25 polymorphonuclear cells per high-power field can be considered an adequate specimen. Typically, the Gram stain is more helpful than culture results in patients already receiving antimicrobial agents that may inhibit bacterial growth in culture.

Nutritional Management Nutritional support is a mandatory but frequently neglected aspect of postoperative care. Because most vascular surgery patients are well nourished prior to surgery, immediate institution of nutritional support is not necessary. Extensive manipulation of the small bowel may cause mechanical ileus, although absorptive capacity is maintained. Transient pancreatitis also can be encountered in aortic surgery from retractor blade pancreatic irritation. Feeding with an elemental formula can be instituted at low rates (30 mL/h) and increased in volume as tolerated. Enteral feedings reduce the risk of septicemia associated with hyperalimentation catheters. This is of particular importance in vascular disease patients who have unincorporated graft surfaces exposed to the circulation. An evaluation developed by Goldman employs nine variables to predict cardiac risk. Unfortunately, it underestimates cardiac complications in vascular patients and is able to predict cardiac mortality in only 50% of cases. An alternative scale includes a history of previous myocardial infarction, congestive heart failure, unstable angina, diabetes, and age over 70. A significantly greater incidence of perioperative cardiac morbidity and mortality occurs in those with abnormal results. A recent study found that 38% of patients with preoperative ischemia had postoperative cardiac events, whereas fewer than 1% of patients without ischemia suffered cardiac morbidity. Continuous preoperative monitoring identifies patients with clinically silent ischemia who might benefit from therapy. Although this method is simple, noninvasive, and inexpensive, it suffers from low sensitivity and has a positive predictive value of only 38%. Because they typically require walking or running, they are not suitable for use in dysvascular patients whose exercise tolerance is limited by claudication. Dipyridamole-Thallium Scintigraphy-In this test, a pharmacologic agent is substituted for exercise to increase coronary artery blood flow. Intravenously administered dipyridamole promotes coronary artery blood flow without increasing myocardial oxygen consumption by increasing the intracellular concentration of adenosine. Prior to administration of dipyridamole, thallium201 is injected to demonstrate areas of myocardial ischemia. Because thallium-201 is preferentially taken up by the normal myocardium, areas of hypoperfusion appear as "cold" spots. If homogeneity improves after dipyridamole is given, thallium redistribution is said to have occurred, and the scan is considered positive. Redistributed areas consist of viable but ischemic myocardium that are at risk for infarction. Areas that fail to improve after dipyridamole infusion probably consist of previously infarcted muscle that is not at risk for a future ischemic event. If nutritional support is required for more than 1 week, a nitrogen balance study should be completed to ensure that protein needs are being met. Management of Ischemic Heart Disease Atherosclerosis is a systemic disease that affects both the peripheral vasculature and the coronary arteries.

Imaging Studies-A chest x-ray should be obtained in patients suspected to have pulmonary edema or other indications of pulmonary compromise medications known to cause miscarriage order 480mg septra overnight delivery. If indicated by either a low blood glucose determination or in the obtunded patient in whom this measurement cannot be made symptoms zoloft dosage too high cheap generic septra uk, 50 mL of 50% dextrose should be given intravenously along with 100 mg thiamine medicine dictionary prescription drugs purchase genuine septra line. Mechanical ventilation may be required both for decreased respiratory drive and for management of pulmonary edema. Pulmonary edema caused by narcotic overdose usually does not respond to the customary regimen of diuretics and preload and afterload reduction, and intubation is often required. Narcotic Antagonists-Several narcotic antagonists have been used-naloxone, naltrexone, nalmefine, nalorphine, and levallorphan; the latter two also have agonist properties. Although naltrexone is longer-acting than naloxone, its use in the acute setting has been disappointing, and naloxone is the drug of choice in this situation. When the abused drug is codeine, pentazocine, or propoxyphene, an initial dose of up to 2 mg naloxone may be required. When effective, an improvement in respiration and mental status typically occurs in less than 2 minutes, often in seconds. If no response to a total dose of 2 mg is seen, the diagnosis of narcotic General Considerations Narcotic abuse is a major problem worldwide. Although the drugs of choice traditionally have been morphine and heroin, the shorter-acting agents such as fentanyl have come into vogue, especially among health care workers. Most narcotics are administered intravenously because of the rapid euphoria they produce. Methadone, a long-acting oral agent, is used commonly in narcotic addiction treatment/maintenance programs. When given to a narcotic-dependent patient, pentazocine may cause withdrawal symptoms. Immediate care of the narcotic overdose or withdrawal patient focuses on resuscitation, stabilization, and use of antidotes. Critical care of patients suffering from narcotic overdose and withdrawal may include the treatment of conditions caused by narcotic use and the sharing of injection needles. These include pulmonary hypertension (presumably from cotton fiber emboli), endocarditis (from bacterial contamination), necrotizing fasciitis, and tetanus. Many patients will use other intoxicants concurrently, such as alcohol or cocaine, which complicates their care. Symptoms and Signs-Patients with opioid overdoses present most commonly with decreased level of consciousness, depressed respiration, and miotic pupils. In severe cases, such as cases of attempted suicide, respiratory depression may be pronounced. Other common findings include hypo- or hyperthermia, emesis, hypoxia, hypotension, and depression of deep tendon reflexes. Many different prescription, over-the-counter, and recreational or abuse drugs fall into this category. Examples include amphetamine and its derivatives, overthe-counter products for appetite control, cold remedies, and stimulants (eg, phenylpropanolamine, caffeine, ephedrine, and pseudoephedrine). Overuse of sympathomimetics causes toxicity by inducing excessive release of neurotransmitters, including epinephrine and norepinephrine, and the subsequent - and -adrenergic effects they produce. The clinical effects that result from any specific sympathomimetic drug depend on the relative - or -adrenergic actions of that drug (eg, phenylpropanolamine is an -selective drug that causes hypertension, diaphoresis, and mydriasis). Duration of toxicity is usually limited; however, patients may demonstrate prolonged toxicity if they ingest bags containing the drug for illicit transport or if they use "Ice," a long-acting, smokable form of methamphetamine. Because the half-life of naloxone is substantially shorter than that of most narcotic agents, repeat dosing may be required to prevent recurrence of respiratory and mental status depression. Continuous administration of naloxone intravenously may be required in some cases to prevent relapse of respiratory depression. Rhabdomyolysis may occur, particularly in patients who have been obtunded for a significant amount of time; if not treated, patients may develop renal failure from the myoglobinuria seen in this condition. Withdrawal Withdrawal from narcotics produces autonomic disturbances, hyperexcitability, and personality changes characterized by drug-seeking behavior.
