[Perinatal and neonatal mortality and morbidity in newborn infants up to 1,000 g]

Abstract

World-wide intensive efforts have been made for more than 20 years to reduce the rate of preterm delivery, but so far without remarkable success. Preterm delivery accounts for 6-9% of all deliveries and very-low-birth-weight infants (< or = 1000 g) total up to about 60% of perinatal mortality. This study reports on a retrospective analysis of fetal outcome with 33 very-low-birth-weight-infants (< or = 1000 g) delivered at the Women's Hospital (University of Rostock) during the time from 1986 to 1992. The rate of early mortality was at 45.2%, survival rate was at 33% (n = 11). Caesarean section with preservation of fetal membranes proved to offer better results of fetal outcome than spontaneous delivery. Comparing the fetal outcome of all patients concerned, it became obvious that newborns whose mothers enjoyed intensive prenatal care had better chances than those newborns whose mothers came to hospital not before onset of preterm labour. From our experiences we conclude that intensive antenatal care with very early assessment of all possible risk factors for preterm labour is the prerequisite to reduce the rate of preterm delivery.
