Neonatal gastro-oesophageal reflux and aspiration — clinical case

Case summary

This thriving preterm infant has effortless posseting and feed-related desaturations with no red flags — a textbook picture of physiologic gastro-oesophageal reflux rather than disease. The clinical skill on display is restraint: resisting the request for a proton-pump inhibitor, confirming that this is physiologic reflux, and managing conservatively while understanding that the feed-related desaturations are most likely coincidental rather than causal. [1]

Assessment and reasoning

The first step is to confirm physiology against disease. The infant is tracking the 10th centile, feeding without distress, has a soft abdomen, and never vomits bile — there are no red flags of failure to thrive, haematemesis, forceful or bilious vomiting, or recurrent aspiration. By the NASPGHAN and ESPGHAN definitions, this is physiologic reflux that needs reassurance, not investigation or acid suppression. [1]

The desaturations clustered after bolus feeds raise the question of reflux-apnoea causation, but the temporal link on a monitor is weak evidence. Reflux and apnoea are both common and frequently coincident in preterm infants, and the randomised trials show that neither thickening nor acid suppression reduces reflux-related apnoea. The safer interpretation is coincidence, with the apnoea investigated and managed on its own merits. [3]

Management

Begin with reassurance and conservative measures, which are the evidence-based foundation of care for physiologic reflux. Explain to the team and the family that reflux is normal, expected, and self-limiting, and that over-treatment harms more than the reflux itself. [1]

The practical conservative measures for this infant are smaller and more frequent bolus volumes, upright positioning after feeds, careful burping, and a pacifier to stimulate swallowing. As a tube-fed preterm infant, review the tube position and consider switching bolus to continuous feeds, which reduces the reflux burden demonstrable on impedance monitoring. [3]

If symptoms remain troublesome after these measures, a short alginate trial is the one drug with reasonable short-term evidence in infants, and the response should be reassessed. A proton-pump inhibitor is not indicated: a 2023 Cochrane review found no convincing evidence that proton-pump inhibitors improve reflux symptoms in infants, and they carry real harm — infection, a necrotising enterocolitis signal in preterm infants, and fracture risk — none of which buys benefit in physiologic reflux. [2]

Disposition and counselling

Counsel the family that physiologic reflux resolves in the vast majority of infants by twelve to eighteen months as upright posture and solid foods take over, and that this infant's growth and absence of red flags predict an excellent outcome. Discharge need not be delayed by reflux alone, provided the infant is thriving, feeding orally, and free of aspiration. [1]

Provide a clear safety-net of the red flags that should prompt review — bile-stained vomit, forceful or projectile vomiting, faltering growth, or respiratory distress — and confirm that no acid suppressant has been started, so there is nothing to wean. The intervention that most helps this family is the confident explanation that the reflux is normal and that the safest treatment is watchful, conservative care. [3]
