title: Obstetrical and neonatal risk factors in very low birth weight infants related to their neurological development.
abstract: An analysis of pre- and perinatal risks in very low birth weight (VLBW) infants showed that children later suffering from severe neurodevelopmental sequelae were exposed to a significantly higher number of risk factors compared to normally developed VLBW controls. This was not only due to a higher incidence of specific risks, but to the accumulation of risk factors, which consequently made an ischaemic or haemorrhagic brain lesion more likely to occur. This result suggests that brain lesions in VLBW infants are essentially multifactorial. The improved outcome of VLBW infants cared for in the NICU of the Children's Hospital of Tübingen during 1977-1983 was accompanied by a decreasing incidence of obstetrical and neonatal risks. This was mainly due to more frequent transport in utero, earlier obstetrical intervention, and immediate postnatal stabilization of the infant's condition. These changes in perinatal care strategy evidently favoured the postnatal course and thus also improved the neurodevelopmental outcome.
