Prostaglandin gel for cervical ripening before induction of labour.

In cases with a low pelvic score (Bishop) before induction of labour a gel was locally applied consisting of 1 mg prostaglandin F2 alpha in 2 ml. The single dose was 1.5 to 2.5 mg prostaglandin F2 alpha. In cases with insufficient effect this therapy was repeated once up to three times. This method reduced the duration of delivery. No maternal side-effects were observed in a total of 220 cases.
