The prediction of fetal pulmonary maturity from amniotic fluid contaminated by vaginal secretion

Many patients are admitted with premature rupture of the membranes draining amniotic fluid contaminated with vaginal secretions, and the fluid is used for tests of fetal pulmonary maturity. Among 15 patients contamination of amniotic fluid by vaginal and cervical secretions was found to result in a rise in the bubble score in 6 and a rise in total phospholipids (TPL) in 12.
