ABSTRACT

The hemodynamic effects of vaginally and intracervically administered prostaglan-din E2 gel were evaluated by pulsed wave color Doppler ultrasound. Twenty term pregnant mothers were recruited. Mothers were randomized to receive either vaginal or intracervical prostaglandin E2 gel. The hemodynamics was assessed by repeated color Doppler velocimetry of the uterine artery and fetal umbilical and middle cerebral arteries; analysis of variance was used to test statistical significance. In the uterine artery a statistically significant rise (P ≤ 0.001) of the pulsatility index (PI) was observed. A slightly higher rise of the PI was observed after intracervical administration, but the difference between the groups was not statistically significant (P = 0.4). The fetal PI remained unchanged both in the umbilical and cerebral vessels throughout the study. The rise in the uterine artery PI is probably caused by an increase in the uterine tone as prostaglandins of the E series usually cause vasodilation. No detectable fetal effects were evident.
