Summary

This study tested whether placing infants under 6 months with moderate to severe bronchiolitis on their stomachs (prone position) while on high-flow oxygen could reduce the need for more intensive breathing support. A total of 452 infants in critical care were randomly assigned to lie on their stomachs or backs. The goal was to see if stomach positioning lowered the rate of needing non-invasive or invasive ventilation within the first three days.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
prone position (lying on stomach)
What this could lead to
If effective, placing infants on their stomachs during high-flow oxygen therapy could reduce the need for more invasive breathing support.
What could go wrong
This is a completed study, but the benefit may depend on how strictly the positioning protocol is followed. Results may not apply to all infants or hospital settings.
