The ideal admission temperature in preterm infants < 33 weeks of gestation

Submitted by: Krithika Lingappan, MD A retrospective observational study of nearly 10,000 neonates neonates  <33 weeks of gestation from 29 NICUs in the Canadian Neonatal Network sought to estimate the admission temperature associated with lowest rates of adverse outcomes. The…

Cooling for HIE – longer and deeper is not better

A randomized factorial-design trial from the Neonatal Research Network compared the effects of cooling babies with HIE to lower levels than  usual (32 degrees C instead of 33.5 degrees C) and for longer than usual (120 hours instead of 72…

Occlusive wrap to prevent heat loss at birth

A multicenter randomized study in 39 NICUs (the largest trial of its kind) compared the effects of applying polyethylene occlusive wrap to preterm infants between 24 – 27 weeks gestation immediately after birth. The study was stopped early when 50%…

Operation Toasty Tot – An intervention to reduce hypothermia

A quality improvement project to reduce admission hypothermia in inborn very-low-birth-weight infants used a bundle of interventions to prevent heat loss from conduction, convection, radiation and evaporation. The interventions did not include increasing delivery room temperature or exothermic mattresses. Over…

Exothermic mattresses to prevent admission hypothermia

A randomized trial from Ireland compared preterm infants less than 31 weeks gestation who underwent temperature management at birth with or without an exothermic mattress. All infants received radiant heat and were placed in a polyethylene bag as well. The trial…
