PGE2 gel for enhancement of priming and induction of labour at term in patients with unfavourable cervix

Fifty women (25 nulliparae and 25 multiparae) with unfavourable cervix at term were enrolled in a clinical experiment to evaluate the safety and efficacy of the intracervical application of 0.5 mg PGE₂ gel for cervical softening and eventual induction of labour; duration of pregnancy (38–42 wk) was confirmed by ultrasonic records. Global analysis revealed 48 (96%) vaginal deliveries, 43 (86%) being spontaneous labour and 5 (10%) instrumentally assisted deliveries (forceps). Caesarean section was required in 2 cases (4%). Three patients, having registered no Bishop score (above 5) progress after the first treatment, went into labour upon the second application of PGE₂ gel. Mean induction-delivery time was 11 h 50 min for nulliparae and 7 h 50 min for multiparae. Mean ROM/amniotomy-delivery time was 5 h 59 min for nulliparae and 3 h 11 min for multiparae. Four neonates with initial Apgar scores below 7 registered immediately higher values after adequate reanimation manouvres.
