For decades, routine gastric residual volume (GRV) monitoring has been embedded in pediatric critical care as a safeguard against aspiration and feeding intolerance — yet the practice was built more on habit than high-quality evidence. A rigorous trial now challenges whether this ubiquitous protocol helps or hinders recovery in some of medicine's most vulnerable patients.

Published in JAMA, this randomized controlled trial compared two feeding management strategies in critically ill children receiving mechanical ventilation: standard care involving GRV checks every six hours versus a protocol that eliminated routine GRV assessment entirely. The non-assessment group showed a measurable reduction in mechanical ventilation duration, a clinically meaningful endpoint in pediatric intensive care where every ventilator-day carries risk of complications including ventilator-associated pneumonia and lung injury. Importantly, the intervention arm also demonstrated improved attainment of nutritional targets, suggesting that withholding feeds based on GRV readings may deprive critically ill children of needed calories without corresponding safety benefit. Survival outcomes were also tracked across both arms.

This finding fits into a growing body of adult critical care evidence questioning GRV monitoring's utility — multiple adult ICU trials and guidelines from SCCM and ESPEN have already moved toward de-emphasizing routine GRV checks. Pediatric critical care has lagged in adopting this shift, in part due to limited high-quality pediatric-specific data. This trial appears to fill that gap directly. The key limitation worth weighing is whether results generalize across different pediatric ICU populations, case mixes, and feeding protocols globally. Still, as a randomized design studying a discrete, modifiable practice, this carries considerable weight. For pediatric intensivists, the evidence now tilts toward abandoning routine GRV checks as a standard of care — an operationally simple change with potentially significant patient benefit.
