Thermoregulation of the Extremely Low Birth Weight Neonate.

Abstract

The birth of an extremely low birth weight (ELBW) neonate is complex because of their immaturity. Respiratory and hemodynamic stabilization often takes precedence in the immediate delivery period. While establishing effective breathing and circulation is vital to the survival of the neonate, it is crucial to understand that other adverse outcomes can occur during the resuscitation and transport of the ELBW neonate. Impaired thermoregulation is one of the most detrimental adverse outcomes during the golden hour period and later in the neonatal intensive care unit. Hypothermia is an independent risk factor for increased morbidity and mortality and can impact multiple body systems, making management even more challenging. This article discusses the physiology of thermoregulation while exploring interventions to maintain normothermia in the ELBW neonate, ultimately improving long-term outcomes.
