Getting nutrition right for mechanically ventilated children in the ICU is one of pediatric critical care's most contested and consequential decisions — and long-held clinical assumptions may be doing more harm than good. This JAMA analysis targets persistent myths surrounding enteral nutrition in pediatric intensive care, a setting where the margin for error is narrow and the stakes are high for both patients and their families.

The piece identifies a central tension in pediatric critical care nutrition: excess enteral feeding increases the risk of serious complications including aspiration, vomiting, and gut pathologies such as necrotizing enterocolitis, while insufficient caloric delivery may impair recovery trajectories and prolong illness. The analysis systematically examines the evidence base — or lack thereof — behind entrenched clinical feeding protocols, challenging assumptions about optimal caloric targets, protein delivery, and timing of nutritional support in children on invasive mechanical ventilation. Specific myths are scrutinized against current trial data, with the piece distinguishing between what practitioners believe to be true and what controlled evidence actually supports.

This kind of evidence audit is particularly valuable in pediatric critical care, where much practice has historically been extrapolated from adult ICU data despite meaningful physiological differences in metabolic demands, gut maturity, and stress responses. The framing of clinical norms as 'myths' signals a shift underway in the field — one that recent randomized trials in pediatric ICU nutrition, including the PICU-up and PEPaNIC trials, have already begun to drive. The PEPaNIC trial notably found that early parenteral nutrition supplementation in critically ill children worsened outcomes compared with late initiation, overturning longstanding practice. An editorial in JAMA carries weight as a consensus-shaping instrument, potentially accelerating protocol revision across institutions. The primary limitation here is that this is expert commentary rather than new primary data, making its influence dependent on the quality of its underlying citations.
