Determination of fetal lung maturity by the comparison of one-dimensional L/S ratio, enzymatic lecithin and S/A ratio
The neonatal respiratory distress syndrome (RDS), which occurs almost exclusively in premature infants, is a disease caused by a surfactant deficiency. The chances of surviving the disease have markedly improved in the last decade. With the introduction of the L/S ratio, which is now an established method, it has been possible for the first time to predict RDS reliably. Widespread application of this method is limited due to the fact that it is relatively staff- and time-consuming.
