| Popis: | Free-flowing amniotic fluid collected vaginally can be used in a reliable way for determination of fetal pulmonary maturity. Lavaging the vaginal/cervical area with sterile saline and examining the lavage fluid for lecithin/sphingomyelin (L/S) spots showed no detectable spots in the supernatants (one exception) and barely detectable L/S spots in the sediment. Vaginal-cervical saline-wash fluids did not affect fluid L/S ratios. Lavaging the vaginal-cervical area with abdominal amniotic fluid did not affect the L/S ratio of the original amniotic fluid. |
