title: Ultrasonography of the internal carotid artery during therapeutic hypothermia.
abstract: The purpose of this study was to determine the accuracy of mean blood flow velocity (mean V) in the internal carotid artery (ICA) for prediction of outcome in infants with hypoxic-ischemic encephalopathy (HIE) exposed to therapeutic hypothermia (TH). Five newborns with HIE who met the criteria for TH were enrolled. Ultrasonography of the right and left ICA was performed before, during, and after TH. Mean V of the sampling point in each ICA was measured. Mean V was suppressed during TH and increased after rewarming in four infants with normal neurological development. In one infant with neurological disability, however, mean V increased during TH and decreased after therapy. In conclusion, cervical ultrasonography for ICA in infants during TH may be useful for the prediction of neurodevelopmental outcome.
