Induction of labor with vaginal prostaglandin E2 pessaries. 1983

T R Varma, and J Norman, and L Cowell

Prostaglandin E2 vaginal pessaries (3 mg) were compared with conventional amniotomy and oxytocin infusion as a method of induction of labor in 160 patients in the study group compared with 160 in the control group. Each group consisted of 100 primigravidae and 60 multigravidae. When the features of labor, delivery and fetal status were analyzed for the study and the control groups, the patients who received PGE2 pessaries had a better outcome. The difference was more significant for those patients with a low Bishop score. Compared with controls, the PGE2-treated patients had fewer cesarean sections either for failed induction or fetal distress (P less than 0.01); the incidence of infants with low Apgar score was significantly less (P less than 0.05) and there were fewer postpartum haemorrhages (P less than 0.01).

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

D005316 Fetal Distress A nonreassuring fetal status (NRFS) indicating that the FETUS is compromised (American College of Obstetricians and Gynecologists 1988).

D006473 Postpartum Hemorrhage Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
