A 19-year-old man has had fever, headache, sore throat, and swelling of the cervical lymph nodes for 5 days. His temperature is 40°C (104° F), pulse is 120/min, respirations are 20/min, and blood pressure is 125/85 mm Hg. There is tender cervical adenopathy and palpable lymph nodes in the axillary and inguinal areas. Leukocyte count is 14,000/mm3 (25% segmented neutrophils, 60% atypical lymphocytes, and 15% monocytes). An asymptomatic 37-year-old African American man comes to the physician for a preemployment examination. A 32-year-old woman comes to the physician because of lethargy and boredom since the birth of her son 5 months ago. The most appropriate next step in diagnosis is measurement of which of the following serum concentrations? She has microalbuminuria; her hemoglobin A1c is 7%, and serum creatinine concentration is 1.

A large number of other observational studies using generally can be relied upon as supporting positive response to similar forms of early quantitative resuscitation in comparable fuid loading. Either intermittent or continuous measurements patient populations have shown signifcant mortality reduction of oxygen saturation were judged to be acceptable. During compared to the institutions’ historical controls (Supplemental the frst 6 hrs of resuscitation, if ScvO2 less than 70% or SvO2 Digital Content 2, http://links. As part of performance improvement programs, attempts to achieve the ScvO2 or SvO2 goal are options. Protocolized, quantitative resuscitation of patients with sepsis- induced tissue hypoperfusion (defned in this document as hypotension persisting after initial fuid challenge or blood lactate concentration ≥ 4 mmol/L). In patients with elevated lactate levels targeting resuscitation to normalize lactate (grade 2C). Routine screening of potentially infected seriously ill patients for severe sepsis to allow earlier implementation of therapy (grade 1C). Cultures as clinically appropriate before antimicrobial therapy if no signifcant delay (> 45 mins) in the start of antimicrobial(s) (grade 1C). At least 2 sets of blood cultures (both aerobic and anaerobic bottles) be obtained before antimicrobial therapy with at least 1 drawn percutaneously and 1 drawn through each vascular access device, unless the device was recently (<48 hrs) inserted (grade 1C). Use of the 1,3 beta-D-glucan assay (grade 2B), mannan and anti-mannan antibody assays (2C), if available and invasive candidiasis is in differential diagnosis of cause of infection. Administration of effective intravenous antimicrobials within the frst hour of recognition of septic shock (grade 1B) and severe sepsis without septic shock (grade 1C) as the goal of therapy. Initial empiric anti-infective therapy of one or more drugs that have activity against all likely pathogens (bacterial and/or fungal or viral) and that penetrate in adequate concentrations into tissues presumed to be the source of sepsis (grade 1B). Antimicrobial regimen should be reassessed daily for potential deescalation (grade 1B). Use of low procalcitonin levels or similar biomarkers to assist the clinician in the discontinuation of empiric antibiotics in patients who initially appeared septic, but have no subsequent evidence of infection (grade 2C). Combination empirical therapy for neutropenic patients with severe sepsis (grade 2B) and for patients with diffcult-to-treat, multidrug- resistant bacterial pathogens such as Acinetobacter and Pseudomonas spp. For patients with severe infections associated with respiratory failure and septic shock, combination therapy with an extended spectrum beta-lactam and either an aminoglycoside or a fuoroquinolone is for P. A combination of beta-lactam and macrolide for patients with septic shock from bacteremic Streptococcus pneumoniae infections (grade 2B). De-escalation to the most appropriate single therapy should be performed as soon as the susceptibility profle is known (grade 2B). Duration of therapy typically 7–10 days; longer courses may be appropriate in patients who have a slow clinical response, undrainable foci of infection, bacteremia with S. Antiviral therapy initiated as early as possible in patients with severe sepsis or septic shock of viral origin (grade 2C). A specifc anatomical diagnosis of infection requiring consideration for emergent source control be sought and diagnosed or excluded as rapidly as possible, and intervention be undertaken for source control within the frst 12 hr after the diagnosis is made, if feasible (grade 1C). When infected peripancreatic necrosis is identifed as a potential source of infection, defnitive intervention is best delayed until adequate demarcation of viable and nonviable tissues has occurred (grade 2B). Selective oral decontamination and selective digestive decontamination should be introduced and investigated as a method to reduce the incidence of ventilator-associated pneumonia; This infection control measure can then be instituted in health care settings and regions where this methodology is found to be effective (grade 2B).
