Prospective study of different methods and routes of administration of prostaglandin E2 to improve the unripe cervix.
Methods of vaginal and extra-amniotic prostaglandin administration to achieve ripening of the cervix as a preliminary to induction of labour are described. Three groups of twenty patients with unfavourable induction features were studied, each receiving prostaglandin E2 the evening prior to planned induction. One group received PGE2 500 micrograms suspended in a viscous medium extra-amniotically. One group received PGE2 3 mg suspended in a viscous medium into the vaginal vault. A third group received a 3 mg PGE2 vaginal pessary to the posterior fornix. Improvement in cervical status at time of induction occurred in all groups but no single group had a significant advantage when regarding mean improvement, the induction-delivery interval or the number of patients in whom labour began before formal induction. However, with regard to relative cost, ease of preparation and storage, as well as patient and medical staff convenience, Prostaglandin E2 in pessary form is a superior form of administration.
