This should be avoided if possible in patients with unstable renal function, anuria, or an increased volume of distribution. Therapeutic drug monitoring is warranted, and more than one drug level may be needed to determine the appropriate dosing interval. Whereas antibiotics or fluids alone did not improve outcome in animal models of septic shock, these interventions were found to act synergistically to improve survival. Survival was similar in the two arms at 28 days, and the two fluids were considered comparable in patients with severe sepsis. Although a meta-analysis found that albumin was associated with lower mortality when compared with other fluids,385 a recent trial found that patients who received crystalloid plus albumin to maintain a serum albumin concentration of 30 g/L were no more likely to survive than were patients who received only crystalloid. The goals of fluid resuscitation in severe sepsis and septic shock are to ensure adequate tissue perfusion by restoring effective intravascular volume (depleted by vasodilation and increases in vascular permeability) and to optimize cardiac output by enhancing venous return and cardiac filling. In most patients, 15 to 30 mL/kg or up to 4 to 6 L of crystalloid may be required in the early phases of resuscitation. Too little fluid may cause tissue hypoperfusion and worsen organ function, whereas excessive fluid administration may impair organ function resulting from tissue edema. However, considerable controversy exists regarding which hemodynamic parameters should guide resuscitation in septic patients. Using this catheter to guide the administration of fluids, vasopressors, dobutamine, or packed red cell transfusions to achieve specific hemodynamic targets was no better than usual care composed of early antibiotics, fluid resuscitation, and, if needed for venous access, a central venous catheter. In particular, a randomized, controlled clinical trial found that lowdose dopamine infusion did not improve survival or prevent renal failure in critically ill patients at risk for renal dysfunction,392 and a similar conclusion was reached by a retrospective analysis of patients with septic shock in a large clinical trial. The doses of vasopressin that increase blood pressure in septic patients are lower than those required in normal individuals. Vasopressin is Intravenous Fluids and Vasopressors Chapter 75 Sepsis,SevereSepsis,andSepticShock AntimicrobialChemotherapyfor SpecificEtiologiesofSevereSepsis Although empirical broad-spectrum regimens will provide agents that are active against most pathogens, some situations may warrant different or additional coverage. For example, tick exposure might warrant treatment with doxycycline (Rocky Mountain spotted fever) or atovaquone-azithromycin for babesiosis (with clindamycin if critically ill) in different exposure environments. In patients with suspected or proven streptococcal myositis/fasciitis or toxic shock syndrome, clindamycin should be given in addition to penicillin G to reduce toxin production. If staphylococcal toxic shock syndrome is considered, clindamycin should be given with either oxacillin (if methicillinsusceptible S. Cefotaxime or ceftriaxone is preferred for asplenic patients, who may have overwhelming bacteremia with S. Nosocomial infections often arise at sites of epithelial barrier disruption and thus frequently involve intravascular catheters, endotracheal tubes (pneumonia and paranasal sinusitis), urinary catheters, and operative wounds or other sites of traumatic injury. In general, when a patient develops severe sepsis, all intravascular and bladder catheters should be removed, with reinsertion at new sites as needed. It is not often necessary to do surgical exploration of an infected thrombus because medical management usually suffices. Annane and co-workers80 found that this occurs most often in patients with impaired adrenal function and that, in such patients, administering hydrocortisone could return the dose-response curve to normal. There is thus a plausible theoretical and experimental basis for using glucocorticoids to treat patients with septic shock. Investigators noted several decades ago that very high doses of corticosteroids were beneficial in animal models of septic shock.
Many of these diseases may be associated with either local or generalized skin lesions antibiotic used for staph buy generic azitrovid 500 mg, including dengue fever antibiotic vs antiviral purchase azitrovid master card, yellow fever infection 4 the day after purchase azitrovid with visa, viral hemorrhagic fevers, malaria, and leptospirosis. In recent years, the number of human viruses in the herpesvirus family has increased from five to eight. Classically, patients with exanthem subitum present with a high fever that lasts from 3 to 5 days. As the temperature normalizes, a macular or maculopapular rash develops, generally beginning on the trunk, with later spread to the extremities and often to the neck and face. Hemorrhagic fever may be caused by viruses belonging to several families, including the Arenaviridae. After an incubation period of 2 to 3 weeks, patients present with abrupt onset of fever in association with malaise, headache, myalgias, back pain, abdominal pain, nausea, and vomiting. Conjunctival injection or hemorrhage with palatal and upper torso petechiae is commonly seen on physical examination. During this phase, a characteristic erythematous flush that blanches with pressure may be observed, usually affecting the face, neck, and upper torso. After the 3- to 7-day febrile phase, a period of hypotension and severe shock ensues that is characterized by hemorrhagic manifestations. Overall, about 20% of the patients manifest severe disease, with death from shock and renal failure in 5% to 10% of cases. The hantavirus pulmonary syndrome may be caused by multiple hantaviruses including Sin Nombre virus. Patients present with an acute onset of fever, severe frontal headache, anorexia, malaise, and myalgias. These signs and symptoms are followed 2 to 3 days later by clinical deterioration heralded by pharyngitis, conjunctivitis, severe nausea and vomiting, abdominal pain, and watery diarrhea. Five days later, patients develop a maculopapular rash on the trunk and back that is followed by the appearance of petechiae, ecchymoses, subconjunctival hemorrhages, epistaxis, hemoptysis, hematemesis, and melena. Patients with Marburg virus infection may develop a scarlatiniform rash rather than a maculopapular rash. Considerations in the differential diagnosis of African hemorrhagic fevers also include yellow fever and Lassa fever, but these illnesses are not accompanied by a rash. Erythema may appear shortly before the onset of fever, concurrently with fever onset, or 24 to 48 hours later. This rash may be noted as a flushing or erythematous mottling beginning on the trunk and spreading centrifugally to the face, neck, and extremities. Flushing may disappear after 1 or 2 days or may blend into an erythematous macular or maculopapular rash that develops at any time during the course of illness. Pruritus and desquamation, especially on the palms and soles, may follow termination of the eruption. Dengue hemorrhagic fever/dengue shock syndrome is a more severe disease whose skin manifestations may include petechiae, purpura, ecchymoses, epistaxis, and gum bleeding. Chikungunya virus is an arbovirus (genus Alphavirus, family Togaviridae) that is prevalent in Africa and Asia, especially in India and islands in the Indian Ocean. Disease has been reported in the United States in travelers returning from endemic areas. Skin involvement is present in 20% to 50% of cases and consists of a pruriginous maculopapular rash mostly located on the face, trunk, and extremities. Hemorrhagic fever has been reported in Chikungunya-infected patients from Thailand.

Increases in serum creatinine usually occur during the second week of therapy and are reversible within 2 to 4 weeks after cessation in most patients infection 3 weeks after wisdom teeth removal buy cheap azitrovid 250 mg on line. High dosages antimicrobial resistance and antibiotic resistance azitrovid 250 mg overnight delivery, rapid or continuous infusion antibiotics for k9 uti cheap azitrovid master card, dehydration, and concurrent use of nephrotoxic drugs are risk factors. Extra saline hydration before and during infusion seems to reduce the risk for nephrotoxicity. Foscarnet is a potent chelator of divalent cations, and metabolic abnormalities are common, including hypocalcemia (15% to 35%); hypomagnesemia (15% to 44%); hypokalemia (10% to 16%); and hypercalcemia, hypophosphatemia, and hyperphosphatemia. Intravenous foscarnet should be administered at a fixed rate (maximum 1 mg/kg/min) by infusion pump, to minimize the possibility of acute metabolic abnormalities. Close monitoring with electrolyte supplementation and foscarnet dosage adjustments are often required during induction therapy. Other reported side effects are fever, generalized rash, diarrhea in 30%, nausea or emesis in up to one half, abnormal liver function tests, anxiety, fatigue, and painful genital ulcerations. Preclinical studies indicate that high concentrations are mutagenic and that foscarnet causes fetal skeletal anomalies in rodents and rabbits. Maintenance dosages of 120 mg/kg/day seem to be more effective in prolonging survival and controlling retinitis. Valganciclovir (Valcyte) is the l-valyl ester of ganciclovir and is rapidly converted to ganciclovir after oral administration. Valganciclovir is a monovalyl ester prodrug that is well absorbed, most likely by intestinal peptide transporter 1, and rapidly hydrolyzed to the parent by intestinal and hepatic esterases. After administration of oral valganciclovir tablets (900 mg) with food, ganciclovir bioavailability is approximately 60%, prodrug blood levels are low (1% to 2% of ganciclovir), ganciclovir peak plasma concentrations average 5. After intravenous dosing, aqueous, vitreous, and subretinal fluid levels are similar to those in serum. Most ganciclovir is eliminated unmetabolized by renal excretion (>90% of dose) by glomerular filtration and tubular secretion. Dosage reductions of ganciclovir (Table 45-7) and valganciclovir (Table 45-8) are necessary in patients with CrCl less than 80 mL/min. Ganciclovir dosing regimens for patients on continuous venovenous hemodiafiltration are suggested. Myelosuppression is the principal dose-limiting toxicity of ganciclovir and its prodrug. Neutropenia occurs in approximately one fourth of patients receiving oral ganciclovir. Neutropenia is most commonly observed during the second week of treatment and is reversible in most patients within 1 week after drug cessation. Recombinant granulocyte macrophage colony-stimulating factor may be useful in treating ganciclovir-induced neutropenia. Approximately 25% of valganciclovir recipients discontinue maintenance therapy within 10 months for toxicity or other reasons. In the event of massive overdosage, hemodialysis and hydration may be effective in reducing plasma ganciclovir levels.
