Filter by:This study will provide pharmacokinetic data for the MVI 100 (100 mcg) misoprostol vaginal insert when administered to nulliparous women at term gestation requiring cervical ripening and induction of labor.
Hypothesis: The induction of labor in patients with unfavorable Bishop score is a challenging obstetrical process, and may be influenced or complicated by the cervical ripening method used. We will conduct a comparative study of the foley catheter vs the cervical ripening double balloon (Cook medical, GPN: G48149). We will compare the failure rates, cesarean section rate, infections and postpartum complications, especially endometritis.
The rate of labor induction is rising throughout the United States for a variety of reasons. Medical conditions that lead to increased risk of prolonging the pregnancy to both mother and fetus are not infrequent. In addition, elective deliveries are becoming more common. Foley balloon catheter placement is a common method used for labor induction in women with an unfavorable cervical assessment. There are several studies using various volumes of Foley balloon catheters for labor induction ranging from 30ml to 80ml, however, there are no studies replicating the findings of the largest study comparing 2 different volumes in the balloon. The investigators plan to compare instillation of 30ml of sterile saline versus 60ml in a Foley balloon catheter for women undergoing induction of labor with an unfavorable cervix. The investigators will observe the following outcomes: rate of delivery within 24 hours, cervical dilation after foley balloon catheter expulsion, insertion to balloon expulsion interval, induction to delivery time interval, peak oxytocin requirement, presence of infection or meconium, cesarean delivery rate, operative vaginal delivery rate, indication for operative vaginal or cesarean delivery, cervical laceration rate, placental abruption rate, 5-minute Apgar score, and umbilical cord arterial blood pH and base excess.
We wish to determine whether patients undergoing cervical ripening with an infusion of saline will have a lower c-section rate than patients who undergo cervical ripening with misoprostol.
Misoprostol (Cytotec®) is a synthetic prostaglandin E1 analog that has been marketed in the United States since 1988 as a gastric cytoprotective agent. In contradistinction to prostaglandin E2 preparations (dinoprostone, Prepidil, Cervidil), misoprostol is inexpensive and available in scored tablets that can be broken and inserted vaginally. Despite a focused campaign by the manufacturer to curtail its use in obstetric practice, misoprostol has, over the past several years, gained widespread acceptance as both a labor induction and a cervical ripening agent. Such off-label indication has been endorsed by the American College of Obstetricians and Gynecologists and other medical bodies. Recently, FDA approved a new label for the use of cytotec during pregnancy which removed pregnancy as a contraindication for its use. Vaginal administration seems to be more efficacious than when given orally, although there is the worry of uterine tachysystole and hyperstimulation with vaginal doses > 50-µg. The use of sublingual misoprostol for cervical ripening at term was recently investigated in two studies that compared it to the oral route, on the assumption that the sublingual route would have the higher efficacy of the vaginal route by avoiding the first pass effects of the gastrointestinal and hepatic systems, while having lower hyperstimulation rates by avoiding the direct effects on the cervix. In addition, the sublingual route would combine an easier administration with the added advantage of no restriction of mobility after administration. There has been no previous report in the literature comparing the use of misoprostol given sublingually to that given vaginally for the induction of labor at term. Our aim is to compare efficacy, safety and patient satisfaction with misoprostol given vaginally (the current standard) to that given sublingually.
