Intravaginal versus intracervical application of prostaglandin E2 in viscous gel for cervical priming and induction of labor at term in patients with an unfavorable cervical state.
Sixty term pregnant women with unripe cervix were randomly given either 0.5 mg of prostaglandin E2 (PGE2) in 2 ml of gel intracervically or 4 mg of PGE2 in 3 ml of gel intravaginally to prime the cervix and/or to induce labor. In patients with a highly unfavorable cervix (cervical score less than or equal to 3), the intracervical application was significantly more effective than the intravaginal. In patients with a more favorable cervical state (cervical score 4 or 5), the two routes of application were equipotent. Gastrointestinal side effects were registered after intravaginal but not after intracervical application. Myometrial activity was significantly more increased after intravaginal than after intracervical gel application. All children were born in good condition with an Apgar score greater than 7 within 5 minutes.
