Fluid resuscitation in pediatric sepsis: FEAST trial implications for resource-limited settings?
6-year-old with septic shock secondary to pneumococcal bacteremia. Weight 20 kg. Presenting with tachycardia (HR 160), delayed capillary refill (4 seconds), altered sensorium (GCS 12), BP 75/40.
The Surviving Sepsis Campaign pediatric guidelines recommend 40 to 60 mL/kg of isotonic crystalloid in the first hour. However, the FEAST trial (2011) showed increased 48-hour mortality with fluid boluses in febrile children in sub-Saharan Africa.
Questions:
- Do you apply FEAST trial results to your practice in Indian hospitals?
- What is your fluid bolus volume and rate in the first hour?
- Norepinephrine vs dopamine as first-line vasopressor in pediatric sepsis?
- Role of point-of-care ultrasound for fluid responsiveness assessment in children?

The FEAST trial is frequently misinterpreted, and I see its shadow in every pediatric sepsis discussion. Here is my position:
1. FEAST applicability: The FEAST trial was conducted in African settings without ICU capacity (no mechanical ventilation, no inotropes, limited monitoring). The mortality signal was likely driven by fluid overload in the absence of advanced supportive care. In Indian tertiary hospitals with PICU capabilities, I do NOT restrict fluid resuscitation based on FEAST.
2. My protocol for the first hour:
- 20 mL/kg NS bolus over 5 to 10 minutes (not faster, to avoid volume overload from overshoot)
- Reassess after each bolus: HR, capillary refill, mental status, urine output
- Repeat up to 40 to 60 mL/kg total in the first hour IF clinical targets are not met
- I reassess hepatomegaly and lung auscultation before each subsequent bolus
3. Vasopressor choice: Norepinephrine is my first-line, aligning with updated SSC pediatric guidelines. We moved away from dopamine based on the adult SOAP-II data extrapolation and the fact that dopamine's variable receptor activity makes it less predictable. I start NE at 0.05 mcg/kg/min via a peripheral IV if central access is delayed (evidence supports peripheral NE for up to 12 hours in an emergency).
4. POCUS for fluid responsiveness: Essential. I use IVC collapsibility index (> 50% variation suggests fluid responsiveness) and aortic velocity time integral (VTI) change with passive leg raise. In younger children where IVC assessment is technically difficult, I rely on VTI.
