Guide to Recommendations’ Strengths and Supporting Evidence:
- 1 = strong recommendation;
- 2 = weak recommendation or suggestion;
- A = good evidence from randomized trials;
- B = moderate strength evidence from small randomized trial(s) or multiple good observational trials;
- C = weak or absent evidence, mostly driven by consensus opinion.
New Fluid Resuscitation Recommendations
- Using crystalloids like normal saline as the initial fluid resuscitation for people with severe sepsis. The initial fluid challenge should be 1L or more of crystalloid, and a minimum of 30 mL/kg of crystalloid (2.1 L in a 70 kg) in the first 4-6 hours. (Grade 1A)
- Incremental fluid boluses should be continued as long as patients continue to improve hemo-dynamically (in blood pressure, delta pulse pressure, or both) (Grade 1C)
- Adding albumin to initial fluid resuscitation with crystalloid for severe sepsis and septic shock (Grade 2B)
- Don't using hetastarches/ hydroxyethyl starches greater than 200 kDa in molecular weight (Grade 1B)
New Recommendations for Vasopressors, Inotropes
- Using norepinephrine (Levophed) as the first choice for vasopressor therapy (Grade 1B). Vasopressin 0.03 units / minute is an alternative to norepinephrine, or may be added to it (Grade 2A)
- When a second agent is needed, epinephrine is weakly-recommended vasopressor choice (Grade 2B)
- Dopamine was only recommended in highly selected patients whose risk for arrhythmias was felt to be very low and who had a low heart rate and/or cardiac output (Grade 2C)
- Dobutamine is strongly recommended (by itself or in addition to a vasopressor) for patients with cardiac dysfunction as evidenced by high filling pressures and low cardiac output, or clinical signs of hypoperfusion after achievement of restoration of blood pressure with effective volume resuscitation (Grade 1C)
- Don't providing intravenous corticosteroid therapy to patients for whom fluid resuscitation and vasopressors can restore an adequate blood pressure. For those with vasopressor-refractory septic shock, they recommend IV hydrocortisone in a continuous infusion totaling 200 mg/24 hrs (Grade 2C)
Other New Surviving Sepsis Guidelines
- Using normalization of lactate levels as an alternate goal in early goal-directed therapy for severe sepsis, if central venous oxygenation monitoring is not available (Grade 2C).
- For patients at risk for fungal infection as a source for severe sepsis, checking one of the newer assays for invasive candidiasis such as 1,3-beta-D-glucan, mannan, or anti-mannan ELISA antibody testing (Grade 2B/C).
- When no infection can be found during empiric antibiotic therapy, consider using a low procalcitonin level as a supportive tool for the decision to stop antibiotics (Grade 2C).
The Surviving Sepsis project was criticized in the mid 2000s when it was revealed that Eli Lilly (makers of since-discontinued Xigris) provided a reported ~90% of the funding, without disclosure by the committee.
