Premature babies can lose body heat quickly after birth, which can lead to serious health problems. This study compared two methods to keep premature babies warm while they were being moved from the delivery room to the neonatal intensive care unit (NICU): wrapping the baby in a plastic bag (polyethylene bag) versus wrapping the baby in a prewarmed blanket, which is the usual method used in many hospitals. Sixty-seven premature babies weighing 2000 grams or less were randomly assigned to receive one of these two methods. The researchers measured the babies' body temperature, heart rate, oxygen levels, and blood sugar at three points: right after birth, during the transfer, and after arriving at the NICU. The goal was to find out whether the plastic bag method was more effective than the blanket method at preventing low body temperature (hypothermia) in these vulnerable babies.
