Embrace versus Cloth Wrap in preventing neonatal hypothermia during transport: a randomized trial



We assessed the efficacy of Embrace Nest Infant Warmer versus Cloth Wrap in preventing hypothermia during short-term transport from the emergency department (ED) to the neonatal intensive care unit (NICU).


Neonates weighing ≥1500 g coming to the ED were randomized for transport to the NICU. Axillary temperature was measured.


A total of 120 newborns (60 per group) were enrolled. From ED exit to NICU entry, the mean (SD) temperature increased in the Embrace group by 0.37 °C (0.54), whereas it reduced by 0.38 °C (0.80) in the Cloth group (p < 0.001). Hypothermia cases reduced in the Embrace group from 39 (65%) to 21 (35%), while it increased from 21 (35%) to 39 (65%) in the Cloth group (p = 0.001) from ED exit to NICU entry. The thermoregulation for 24 h after admission to the NICU was superior in the Embrace group.


Embrace showed significantly better thermoregulation in neonates. Further studies should be done to measure its effectiveness in different environments and distances.
