Hemodynamics among neonates with hypoxic-ischemic encephalopathy during whole-body hypothermia and passive rewarming.

Objective: To assess changes in cardiac performance, with Doppler echocardiography, among newborns with hypoxic-ischemic encephalopathy during mild therapeutic hypothermia and during rewarming.

Methods: For 7 asphyxiated neonates (birth weight: 1840-3850 g; umbilical artery pH: 6.70-6.
