Description
Summary:•Warming procedures are recommended for newborns in the delivery room.•Radiant warmer + polyethylene bag increases the risk of hyperthermia.•Heat stress can occur in only 11 min in extreme conditions.•Continuous body temperature monitoring is required in the delivery room. The efficacy and safety of three polyethylene bags commonly used to prevent hypothermia in premature infants was assessed. To simulate transfer from the delivery room to a secondary care unit, a thermally stable, bonneted mannequin (skin temperature: 34.4 °C) was placed in a climate chamber under different conditions: with a radiant warmer, with various polyethylene bags (open on one side, closed by a draw-string at the neck, or a “life support pouch” with several access points) or without a bag. With the radiant warmer turned on, the mean reduction in heat loss from the nude mannequin was 50.8 ± 1.7% (p
