Perinatal asphyxia may lead to neurologic injury and death of the newborn infant. Hypothermia therapy seems to lower this risk. For the present retrospective study, the patient record data of both the mother and the child were collected for the newborn infants treated with hypothermia therapy in 2007-2010 in Helsinki University Central Hospital. Of the 61 children treated with hypothermia therapy, 12 died. Resuscitation response, severity of hypoxic-ischemic encephalopathy, EEG and MRI findings may provide more information than the baseline condition about the prognosis of infants treated with hypothermia therapy.
