Suspected sepsis
- Fever (>38.3°C)
- Hypothermia (core temperature <36°C)
- Heart rate >90/min–1 or more than two SD above the normal value for age
- Tachypnea
- Altered mental status
- Significant edema or positive fluid balance (>20 mL/kg over 24 hr)
- Hypotension (SBP <90 mm Hg, MAP <70 mm Hg, or an SBP decrease >40 mm Hg)
- Hypoxemia (Pao2/Fio2 <300)
- Acute oliguria (urine output <0.5 mL/kg/hr for at least 2 hrs despite adequate fluid resuscitation)
- Ileus (absent bowel sounds)
- Diminished capillary refill or mottling
- Hyperglycemia (plasma glucose >140mg/dL or 7.7 mmol/L) in the absence of diabetes
- Leukocytosis (WBC count >12,000 μL–1)
- Leukopenia (WBC count <4000 μL–1)
- Bandemia >10% immature forms
- C-reactive protein more than two SD above the normal value
- Procalcitonin greater than two SD above the normal value
- Creatinine increase >0.5mg/dL or 44.2 μmol/L
- Coagulation abnormalities (INR >1.5 or aPTT >60 s)
- Thrombocytopenia (platelet count <100,000 μL–1)
- Hyperbilirubinemia (plasma total bilirubin >4mg/dL or 70 μmol/L)
- Hyperlactatemia (>1 mmol/L)

Early Goal-Directed Therapy
- Supplemental oxygen ± intubation / ventilatory support ± sedation
- Arterial and central venous line placement
Rivers Protocol
- Infuse a 500-ml bolus of crystalloid q 30 minutes to maintain CVP at 8–12 mm Hg.
- If MAP <65 mm Hg, administer vasopressors to maintain MAP at ≥65 mm Hg.
- If MAP >90 mm Hg, administer vasodilators until MAP ≤90 mm Hg.
- If ScvO2 <70%, transfuse RBC to maintain Hct at ≥30%.
- Once CVP/MAP/Hct are optimized, if ScvO2 is still <70%, load dobutamine 2.5 μg/kg/min.
- Titrate dobutamine by 2.5 μg/kg/min q 30 minutes until 20 μg/kg/min or ScvO2 ≥70%.
- Taper or discontinue dobutamine if MAP <65 mm Hg or HR >120 bpm.
Surviving Sepsis Campaign Care Bundles
TO BE COMPLETED WITHIN 3 HOURS:
- Measure lactate level
- Obtain ≥2 sets of blood cultures prior to administration of antibiotics
- Administer 30 mL/kg crystalloid for hypotension or lactate ≥4 mmol/L
- Administer empiric antibiotics (details)
TO BE COMPLETED WITHIN 6 HOURS:
- Administer vasopressors for persistent hypotension to maintain MAP ≥65 mm Hg
- For septic shock or initial lactate ≥4 mmol/L (36 mg/dL):
- — Measure CVP (target ≥8 mm Hg)
- — Measure ScvO2 (target ≥70%)
- Remeasure lactate if initial lactate was elevated
