Overview
The therapy of sepsis rests on antibiotics, surgical drainage of infected fluid collections, fluid replacement and appropriate support for organ dysfunction. This may include hemodialysis in kidney failure, mechanical ventilation in pulmonary dysfunction, transfusion of blood products, and drug and fluid therapy for circulatory failure. Ensuring adequate nutrition, if necessary by parenteral nutrition, is important during prolonged illness.
Supportive trial [1]
- A problem in the adequate management of septic patients has been the delay in administering therapy after sepsis has been recognized. * Published studies have demonstrated that for every hour delay in the administration of appropriate antibiotic therapy there is an associated 7% rise in mortality.
- A large international collaboration was established to educate people about sepsis and to improve patient outcomes with sepsis, entitled the "Surviving Sepsis Campaign."
- The Campaign has published an evidence-based review of management strategies for severe sepsis,[2] with the aim to publish a complete set of guidelines in subsequent years.

Antibiotic therapy1. The guideline committee recommends that intravenous antibiotic therapy be started as early as possible and within the first hour of recognition of septic shock (Grade 1B) and severe sepsis without septic shock (Grade 1D). Appropriate cultures should be obtained before initiating antibiotic therapy, but should not prevent prompt administration of antimicrobial therapy. (Grade 1D) 2a. The guideline committee recommends that initial empirical anti-infective therapy include one or more drugs that have activity against all likely pathogens (bacterial and/or fungal) and that penetrate in adequate concentrations into the presumed source of sepsis. (Grade 1B) 2b. The guideline committee recommends that the antimicrobial regimen be reassessed daily to optimize activity, to prevent the development of resistance, to reduce toxicity, and to reduce costs. (Grade 1C) 2c. The guideline committee suggests combination therapy for patients with known or suspected Pseudomonas infections as a cause of severe sepsis. (Grade 2D) 2d. The guideline committee suggests combination empiric therapy for neutropenic patients with severe sepsis. (Grade 2D) 2e. When used empirically in patients with severe sepsis, the guideline committee suggests that combination therapy should not be administered for more than 3 to 5 days. De-escalation to the most appropriate single therapy should be performed as soon as the susceptibility profile is known. (Grade 2D) 3. The guideline committee recommends that the duration of therapy typically be 7 to 10 days; longer courses may be appropriate in patients who have a slow clinical response, undrainable foci of infection, or who have immunologic deficiencies including neutropenia. (Grade 1D) 4. If the presenting clinical syndrome is determined to be due to a noninfectious cause, the guideline committee recommends antimicrobial therapy be stopped promptly to minimize the likelihood that the patient will become infected with an antibiotic resistant pathogen or will develop a drug related adverse effect. (Grade 1D)

Surviving sepsis campaign: international guidelines for source control of severe sepsis and septic shock: 2008 (DONOT EDIT) [1]

Source control1a. The guideline committee recommends that a specific anatomic diagnosis of infection requiring consideration for emergent source control- for example necrotizing fasciitis, diffuse peritonitis, cholangitis, intestinal infarction – be sought and diagnosed or excluded as rapidly as possible (Grade 1C) and within the first 6 hours following presentation (Grade 1D). 1b. The guideline committee further recommends that all patients presenting with severe sepsis be evaluated for the presence of a focus of infection amenable to source control measures, specifically the drainage of an abscess or local focus of infection, the debridement of infected necrotic tissue, the removal of a potentially infected device, or the definitive control of a source of ongoing microbial contamination (Grade 1C) 2. The guideline committee suggests that when infected peripancreatic necrosis is identified as a potential source of infection, definitive intervention is best delayed until adequate demarcation of viable and non-viable tissues has occurred. (Grade 2B) 3. The guideline committee recommends that when source control is required, the effective intervention associated with the least physiologic insult be employed, for example, percutaneous rather than surgical drainage of an abscess. (Grade 1D) 4. The guideline committee recommends that when intravascular access devices are a possible source of severe sepsis or septic shock, they be promptly removed after establishing other vascular access. (Grade 1C)

Fluid Therapy1. The guideline committee recommends fluid resuscitation with either natural/artificial colloids or crystalloids. There is no evidence-based support for one type of fluid over another. (Grade 1B) 2. The guideline committee recommends fluid resuscitation initially target a CVP of at least 8 mm Hg (12 mm Hg in mechanically ventilated patients). Further fluid therapy is often required. (Grade 1C) 3a. The guideline committee recommends that a fluid challenge technique be applied, wherein fluid administration is continued as long as the hemodynamic improvement (for example, arterial pressure, heart rate, urine output) continues. (Grade 1D) 3b. The guideline committee recommends fluid challenge in patients with suspected hypovolemia be started with at least 1000 mL of crystalloids or 300 to 500 mL of colloids over 30 minutes. More rapid administration and greater amounts of fluid may be needed in patients with sepsis induced tissue hypoperfusion (see initial resuscitation recommendations). (Grade 1D) 3c. The guideline committee recommends the rate of fluid administration be reduced substantially when cardiac filling pressures (CVP or pulmonary artery balloon-occluded pressure) increase without concurrent hemodynamic improvement. (Grade 1D)
