Surfactant

Active

Description

Surfactant is a complex mixture of lipids, proteins, and carbohydrates. Most of the lipids are phospholipids including lecithin (L), sphingomyelin (S), disaturated lecithin, phosphatidyl inositol (PI), and phosphatidyl glycerol (PG). All of these phospholipids are manufactured by the fetal lung, possess surface tension activity, and are secreted into the amniotic fluid. Lecithin is present in the lung in the highest concentration, but must be stabilized by PI and/or PG to have maximal surface tension reducing activity. The relative concentrations of these phospholipids determine the degree of fetal lung maturity. The fetal risk of RDS can be estimated by measuring the amniotic fluid phospholipid concentrations.
