title: [Lung maturation therapy with glucocorticoids in threatened premature labor. Considerations of risk-benefit in evidence-based medicine].
abstract: Prematurity is a major cause of perinatal morbidity and mortality. Antenatal administration of glucocorticoids improves the neonatal outcome of preterm born infants. 1994 the NIH published recommendations for the use of glucocorticoids for women at risk of preterm delivery. A recent evaluation by the Cochrane Collaboration in 1999 showed that antenatal administration of glucocorticoids significantly reduced the rate of RDS and IVH in the gestational age between 24 and 34 weeks. Consequences of repeated courses of antenatal glucocorticoids are not sufficiently studied. The effectivity and safety regarding birth weights, infectious diseases, and the best timing remains unknown. Administration of glucocorticoids lowers fetal activity and heart rate variability. Effects on fetal growth, maternal and fetal immunosystem, and the development of atopic diseases are controversely discussed. Thus preterm labour not leading to a cervical ripening is not necessarily a reason for antenatal glucocorticoids. Antenatal glucocorticoids with PROM do not lower the rate of RDS but of IVH. No prospective randomized trial evaluated the effectivity of antenatal glucocorticoids in diabetes mellitus and IUGR. In preeclampsia beta-methason could improve the rate of RDS and the neonatal outcome. Still our knowledge of antenatal glucocorticoid administration is not sufficient. But despite possible (longtime-) risks for mother and child the administration of glucocorticoids according to the guidelines of the NIH is a major part in the treatment of prematurity and improves the outcome of premature infants. The indication for multiple courses of glucocorticoids should be considered carefully.
