Abstract

We studied periventricular/intraventricular type intracranial hemorrhage (ICH) by cranial ultrasonography in 82 low-birth-weight (LBW) newborn infants with admission hypothermia against the gestational-age-matched 82 normothermic neonates. The incidence of ICH was higher in the hypothermic infants during the 1st week of life (34/82 vs 20/82, P less than 0.02). Although the distribution of individual grades of ICH was not significantly different between the groups, the first ultrasound scan showed higher incidence of major ICH (grades 3 and 4) in the hypothermic infants. Most of the minor ICH (grades 1 and 2) after the first ultrasound appeared in infants who were small for their gestational age. Our data do not support the contention that admission hypothermia can precipitate the development of IVH in LBW infants. However, the detection of admission hypothermia in a LBW neonate should make one suspect the possibility of ICH and regard it as a manifestation of the severity of ICH rather than the cause. Most likely, this close relationship between hypothermia and neonatal ICH originates from perinatal asphyxia and the cumulative adverse effects of asphyxia-related events.
