Plastic bag beats blanket for preemie warmth?
NCT ID NCT07661511
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether wrapping premature babies in a plastic bag (polyethylene bag) keeps them warmer than the usual prewarmed blanket during transfer from the delivery room to the NICU. Sixty-seven babies weighing 2 kilograms or less were randomly assigned to one of the two methods. Researchers measured body temperature, heart rate, oxygen levels, and blood sugar to see which method better prevents hypothermia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Neonatal polyethylene bag (Neohelp®) and prewarmed blanket
- What this could lead to
- If the plastic bag works better, it could become a simple, low-cost way to prevent dangerous heat loss in premature babies during transfer.
- What could go wrong
- This is a small pilot study with only 67 babies, so results may not apply to all hospitals or situations. The plastic bag might not be as effective or safe in larger, more diverse groups.
