Risk Factors for Admission Hyperthermia and Associated Outcomes in Infants Born Preterm

Maternal, placental, and neonatal factors were compared between infants born at <= 29 weeks of gestational age with admission hyperthermia (>37.5 degrees C) and euthermia (36.5-37.5 degrees C). Admission hyperthermia was associated with longer duration of face-mask positive-pressure ventilation and infant's temperature >= 37.5 degrees C in the delivery room. Infants born preterm with admission hyperthermia had greater odds of developing necrotizing enterocolitis and neurodevelopmental impairment.
