Surfactant sufficiency for immature infants--prenatal induction vs. postnatal treatment.
The prenatal and postnatal therapeutic management of surfactant insufficiency are reviewed. Prenatal maternal glucocorticoid therapy promotes lung maturation and enhances lung surfactant levels in the neonate, but a minimum of 24 hr treatment is required and the therapy is of limited effectiveness even under optimal conditions. Relatively few women in premature labour are good candidates for glucocorticoid therapy. Research into combinations of glucocorticoids with hormones (e.g. thyroid), and adrenergic agents in progress. The authors are studying the effects of fibroblast-pneumonocyte factor (FPF) on the fetal lung surfactant system. Postnatal therapy with insufflated natural and artificial surfactants has been studied in several centres with varying degrees of success. Currently, the risk:benefit ratios favour attempts to reduce the risks of respiratory distress syndrome (RDS) by both prenatal surfactant induction and postnatal replacement therapy. Greater understanding of the underlying mechanisms should permit the establishment of more satisfactory treatment.
