Hypoxic Ischemic Encephalopathy (HIE) is a condition caused by impaired cerebral blood flow and brain hypoxia/ischemia in the newborn period. It is recommended to use the term HIE rather than "perinatal asphyxia" or "birth asphyxia" since the time of injury can be difficult to ascertain. Treatment involves supportive care including seizure control and therapeutic hypothermia in some cases. Outcomes range from normal to death or long-term disabilities like cerebral palsy and epilepsy depending on the severity of the initial injury.
