Cervical ripening with intravaginal prostaglandin E2 gel. 1983

R P Prins, and R N Bolton, and C Mark, and D R Neilson, and P Watson

Ripening of the cervix by intravaginal application of a prostaglandin-containing gel is evaluated. Thirty patients with an unfavorable cervix needing labor induction were studied in a double-blind, prospective fashion. The prostaglandin gel proved superior to placebo in ripening the cervix (P less than .05), reducing induction failures (P less than .025), diminishing the oxytocin dosage necessary for induction (P less than .05), and lowering the rate of cesarean section (.05 less than P less than .1). One hundred fifty additional patients with varying Bishop scores and differing clinical situations were also studied. There were 35 cesarean sections (23.3%), nine failed inductions (6%), a spontaneous labor rate of 46%, and an average Bishop score change of 2.5. Twenty patients with premature rupture of the membranes and an unfavorable cervix received a modified gel containing 2.5 mg of prostaglandin E2. Average Bishop score change was 2.9, and there was a 55% incidence of spontaneous labor.

UI	MeSH Term	Description	Entries
D007743	Labor, Obstetric	The repetitive uterine contraction during childbirth which is associated with the progressive dilation of the uterine cervix (CERVIX UTERI). Successful labor results in the expulsion of the FETUS and PLACENTA. Obstetric labor can be spontaneous or induced (LABOR, INDUCED).	Obstetric Labor

Three of the six naturally occurring prostaglandins. They are considered primary in that no one is derived from another in living organisms. Originally isolated from sheep seminal fluid and vesicles, they are found in many organs and tissues and play a major role in mediating various physiological activities.	PGE
D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
