FIRE: Focused Initial Rapid Evaluation

Focused Initial Rapid Evaluation (FIRE) should be undertaken to identify patients requiring urgent intervention.

Suspected sepsis (details)


Signs and Symptoms

  • 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

Laboratory Findings

  • 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
— Measure ScvO2
  • Remeasure lactate if initial lactate was elevated

Goals of Initial Resuscitation


  • CVP 8–12 mm Hg
  • MAP ≥65 mm Hg
  • Urine output ≥0.5 mL/kg/hr
  • ScvO2 ≥70% or MvO2 ≥65%
  • Normalization of lactate
