Abstract：
:We have examined the trend in the incidence and mortality of intraventricular hemorrhage (IVH) in low birthweight infants from 1981 through 1984. During this time we admitted 407 infants in the first week of life with a birthweight less than or equal to 1500 gm in whom a cranial ultrasonogram or autopsy had been performed. Though the mean birthweight and gestational age, proportion of infants who were inborn, and percentage of infants requiring mechanical ventilation did not change over the 4 years, cesarean deliveries were performed more frequently (P less than .001). The overall incidence of IVH was 62% in 1981, 56% in 1982, 49% in 1983, and 58% in 1984, thus no significant trend was evident. Although the incidence of minor hemorrhages (grades I and II) remained relatively constant, there was a decrease in the incidence of grade III IVH (1981, 11%; 1984, 2%, P = .01). The incidence of grade IV hemorrhage did not change during the 4 years and ranged from 7 to 9%. Mortality rate for all infants weighing less than or equal to 1500 gm and for infants with a minor hemorrhage remained unchanged; however, the mortality rate for infants with a major hemorrhage (grade III or IV) tended to decrease (P = .07). We conclude that although some minor changes in the incidence and mortality have occurred, IVH continues to be a major problem in very-low-birthweight infants at our institution.
