  • Labor and Vaginal Delivery
    VI LABOR, DELIVERY, AND POSTPARTUM LABOR AND VAGINAL DELIVERY Kelly A. Best, MD CHAPTER 61 1. What is the definition of labor? Labor begins when uterine contractions of sufficient frequency, intensity, and duration are attained to bring about effacement and progressive dilation of the cervix. 2. What two steps are theorized to be crucial to the initiation of labor in human pregnancy? 1. Retreat from pregnancy maintenance 2. Uterotonic induction Despite extensive investigation into the associated physiologic and biochemical changes, the physiologic processes in human pregnancy that result in the onset of labor are still not defined. 3. In which patients is induction of labor considered? Awaiting the onset of normal labor may not be an option in certain circumstances. At preterm gestations, indications for labor induction include severe preeclampsia, fetal growth restriction with abnormal antepartum surveillance or other evidence of fetal compromise, and deterioration of maternal disease to the point that continuation of pregnancy is believed to be detrimental. In cases of rupture of membranes without labor (i.e., premature rupture of membranes) at term (37 to 42 weeks) or postterm (≥42 weeks), induction of labor is often performed. 4. What is a Bishop score, and how is it used? A Bishop score is a quantifiable method to assess the likelihood of a successful induction. Elements include dilation, effacement, station, consistency, and position of the cervix (Table 61-1). A score of 6 or less trans- lates into a need to ripen the cervix and is associated with less successful inductions. A score 8 or greater generally means the cervix does not need ripening and induction is more likely to be successful.

  • Intra-Vaginal Prostaglandin E2 Versus Double-Balloon Catheter for Labor Induction in Term Oligohydramnios
    Journal of Perinatology (2015) 35, 95–98 © 2015 Nature America, Inc. All rights reserved 0743-8346/15 www.nature.com/jp ORIGINAL ARTICLE Intra-vaginal prostaglandin E2 versus double-balloon catheter for labor induction in term oligohydramnios G Shechter-Maor1, G Haran1, D Sadeh-Mestechkin1, Y Ganor-Paz1, MD Fejgin1,2 and T Biron-Shental1,2 OBJECTIVE: Compare mechanical and pharmacological ripening for patients with oligohydramnios at term. STUDY DESIGN: Fifty-two patients with oligohydramnios ⩽ 5 cm and Bishop score ⩽ 6 were randomized for labor induction with a vaginal insert containing 10 mg timed-release dinoprostone (PGE2) or double-balloon catheter. The primary outcome was time from induction to active labor. Time to labor, neonatal outcomes and maternal satisfaction were also compared. RESULT: Baseline characteristics were similar. Time from induction to active labor (13 with PGE2 vs 19.5 h with double-balloon catheter; P = 0.243) was comparable, with no differences in cesarean rates (15.4 vs 7.7%; P = 0.668) or neonatal outcomes. The PGE2 group had higher incidence of early device removal (76.9 vs 26.9%; P = 0.0001), mostly because of active labor or non-reassuring fetal heart rate. Fewer PGE2 patients required oxytocin augmentation for labor induction (53.8 vs 84.6% P = 0.034). Time to delivery was significantly shorter with PGE2 (16 vs 20.5 h; P = 0. 045) CONCLUSION: Intravaginal PGE2 and double-balloon catheter are comparable methods for cervical ripening in term pregnancies with oligohydramnios.

  • Misoprostol Tablets
    Cytotec® misoprostol tablets WARNINGS CYTOTEC (MISOPROSTOL) ADMINISTRATION TO WOMEN WHO ARE PREGNANT CAN CAUSE BIRTH DEFECTS, ABORTION, PREMATURE BIRTH OR UTERINE RUPTURE. UTERINE RUPTURE HAS BEEN REPORTED WHEN CYTOTEC WAS ADMINISTERED IN PREGNANT WOMEN TO INDUCE LABOR OR TO INDUCE ABORTION. THE RISK OF UTERINE RUPTURE INCREASES WITH ADVANCING GESTATIONAL AGES AND WITH PRIOR UTERINE SURGERY, INCLUDING CESAREAN DELIVERY (see also PRECAUTIONS and LABOR AND DELIVERY). CYTOTEC SHOULD NOT BE TAKEN BY PREGNANT WOMEN TO REDUCE THE RISK OF ULCERS INDUCED BY NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs) (see CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS). PATIENTS MUST BE ADVISED OF THE ABORTIFACIENT PROPERTY AND WARNED NOT TO GIVE THE DRUG TO OTHERS. Cytotec should not be used for reducing the risk of NSAID-induced ulcers in women of childbearing potential unless the patient is at high risk of complications from gastric ulcers associated with use of the NSAID, or is at high risk of developing gastric ulceration. In such patients, Cytotec may be prescribed if the patient has had a negative serum pregnancy test within 2 weeks prior to beginning therapy. is capable of complying with effective contraceptive measures. has received both oral and written warnings of the hazards of misoprostol, the risk of possible contraception failure, and the danger to other women of childbearing potential should the drug be taken by mistake. will begin Cytotec only on the second or third day of the next normal menstrual period. DESCRIPTION Cytotec oral tablets contain either 100 mcg or 200 mcg of misoprostol, a synthetic prostaglandin E1 analog. 1 Reference ID: 4228046 Misoprostol contains approximately equal amounts of the two diastereomers presented below with their enantiomers indicated by (±): Misoprostol is a water-soluble, viscous liquid.
