The effectiveness of intracervical prostaglandin E2 (PGE2) was studied in 9
6 primigravidas with unfavorable cervix and need for induction of labor. Gr
oup A consisted of 49 oligohydramnios and group B of 47 cases with normal a
mniotic fluid volume (controls). A single dose of 0.5 mg PGE2 gel was appli
ed intracervically and several parameters were recorded during the next hou
rs. The mean number of uterine contractions increased during the first 2 h
in both groups, decreased during the next one and did not change significan
tly afterwards, The mean fetal heart rate (FHR) in group A decreased during
the first 2 h and then increased, staying always within normal limits. The
mean FHR in group B increased for 2 h, decreased during the next hour and
did not change significantly afterwards. No significant differences were fo
und between the two groups regarding mode of delivery, Apgar score and neon
atal acidosis. Intracervical PGE2 appeared to effectively stimulate cervica
l ripening and labor induction in oligohydramnios, without causing side eff
ects to the uterus and fetus. Copyright (C) 2000 S. Karger AG, Basel.
