A ventilated ICU patient following major abdominal surgery is unable to commence enteral nutrition due to high gastric residuals. According to ESPEN 2023 guidelines, which route and timing of nutrition support is recommended?
- A Parenteral nutrition started immediately on day 1 ICU
- B Early post-pyloric (nasojejunal) enteral nutrition initiated within 24–48 hours ✓
- C Enteral nutrition withheld until post-operative ileus resolves completely
- D Oral sip feeds only, no tube feeding in the first week
Explanation
ESPEN 2023 and SCCM guidelines recommend early enteral nutrition (within 24–48 hours of ICU admission) as first-line in critically ill surgical patients as it preserves gut mucosal integrity, prevents bacterial translocation, and reduces infections. If gastric intolerance (high residuals >500 mL) persists despite prokinetics (metoclopramide, erythromycin), post-pyloric (nasojejunal or nasoduodenal) feeding should be initiated. Parenteral nutrition is reserved for patients in whom enteral route is contraindicated or insufficient after 3–7 days of failed enteral attempts.
