[Controlled modification of fetal lung-maturity using dexamethasone]

A report is given on the induction of the fetal lung-maturity by administering glucocorticoide dexamethazone to the mother. The lecithin-level and the L/S ratio are established in amniotic fluid before and after tthe treatment. Before the 32. week of gestation no influence of the phospholipidlevel was evident. After the 32. week and after treatment the physiological increase is deeper. Propositions of treatment for premature and induced premature delivery are given corresponding to the results.
