Etiology
Hypothermia may be caused by environmental factors, disorders that impair thermoregulation (eg, sepsis [see Neonatal Sepsis], intracranial hemorrhage [see Intracranial Hemorrhage], drug withdrawal [see Prenatal Drug Exposure]), or a combination. Risk factors for hypothermia include maternal hypertension (see Hypertension in Pregnancy), cesarean delivery (see Cesarean Delivery), and low Apgar scores (see Assessment).
