Current gestational age-related incidence of major intraventricular hemorrhage.

ABSTRACT

The overall incidence of germinal matrix intraventricular hemorrhage (GMIVH) for an inborn population of 250 very low birth weight infants from 1991 through 1993 was 20%; the incidence of major GMIVH was 5.2%. Of infants < or = 25 weeks, 60% survived and 94% of the survivors were free of major GMIVH, whereas 94% of infants > or = 25 weeks survived and 99% had no major GMIVH.
