HYPOXIC-ISCHEMIC ENCEPHALOPATHY (HIE)

Half of all infants with hypoxic-ischemic encephalopathy (HIE) enrolled in a large clinical trial either died or had neurodevelopmental impairment at age 2 years despite receiving therapeutic hypothermia.Severe brain injury and a global pattern of brain injury on MRI were both strongly associated with death or neurodevelopmental impairment.Infants with mild or moderate brain injury had similar mean BSID-III cognitive, language, and motor scores as infants with no brain injury on MRI.Given the prognostic uncertainty of brain MRI among infants with less severe degrees of brain injury, families should be counseled regarding a range of possible neurodevelopmental outcomes.
