Lecithin concentration has been determined in 476 samples of amniotic fluid collected within 72 hours of delivery. If delivery is associated with a level of lecithin of 0.100 mg/100 ml. of lecithin phosphorus or greater, the risk of RDS in the neonate is minimal, if any. If delivery is associated with a level of lecithin less than 0.100 mg/100 ml. of lecithin phosphorus, a definite risk of RDS is present. This "risk factor" is a function of the lecithin concentraion and may be expressed in… CONTINUE READING
