title: Central nervous system hypoxia in children due to near drowning.
abstract: Fourteen children who experienced acute, profound central nervous system hypoxia secondary to near drowning, aspiration, or respiratory arrest underwent CT examination. During the first week after the episode, the most frequent finding was a loss of gray-white matter differentiation. Other findings included effacement of sulci and cisterns, focal areas of edema in the cerebral cortex or basal ganglia, and hemorrhagic infarctions of the basal ganglia. Subsequent CT scans obtained from two weeks to five months after the hypoxic episode showed progression of cerebral loss from cortical infarction with gyral hemorrhage and enhancement to global parenchymal atrophy. The prognosis is poor in these patients: seven children experienced severe neurologic deficits and seven died.
