Abstract

Hypoxia-ischemia in the perinatal period is a serious condition affecting infants, which can result in death and cerebral palsy and associated disabilities. There has been significant research progress in hypoxic-ischemic encephalopathy over the last 2 decades. Many new molecular mechanisms of asphyxia have been identified. Despite all these advances, therapeutic interventions in HIE remain to be limited. Recently it has been revealed that mild therapeutic hypothermia is the only modality shown to improve neurologic outcome. The authors present a summary of pathogenesis of HIE, animal studies of cooling for hypoxic and ischemic models, and first publications on human therapeutic hypothermia trials. The diagnosis of encephalopathy in full-term neonates and enrollment criteria for hypothermia are also discussed. The current data from randomized control trials of hypothermia as neuroprotection for full and near-term infants are presented along with the results of metaanalyses of these trials. Finally, the status of ongoing neonatal hypothermia trials as well as status of therapeutic hypothermia in Poland is summarized.
