oxytocin rupture of membranes

AIM: Cervical ripening is commonly performed before oxytocin administration during labor induction in pregnant women with an unfavorable cervix. In Japan, a controlled-release Dinoprostone vaginal insert (CR-DVI) was approved in 2020. Although many studies have compared the mechanical methods of ripening and prostaglandins, few have examined the impact of additional options for labor induction. This study aimed to assess the impact of CR-DVI as an additional option for labor induction in women with an unfavorable cervix...

Parturition is a complex physiological process that must occur in a reliable manner and at an appropriate gestation stage to ensure a healthy newborn and mother. To this end, hormones that affect the function of the gravid uterus, especially progesterone (P4) and 17ß-estradiol (E2), oxytocin (OT) and prostaglandins (PGs) play pivotal roles. P4 via the nuclear P4 receptor (PR) promotes uterine quiescence and for most of pregnancy exerts a dominant block to labor. Loss of the P4 block to parturition in association with a gain in pro-labor actions E2 are key transitions in the hormonal cascade leading to parturition...

Clinical chorioamnionitis, the most common infection-related diagnosis in labor and delivery units, is an antecedent of puerperal infection and neonatal sepsis. The condition is suspected when intrapartum fever is associated with two other maternal and fetal signs of local or systemic inflammation (eg, maternal tachycardia, uterine tenderness, maternal leukocytosis, malodorous vaginal discharge or amniotic fluid, and fetal tachycardia). Clinical chorioamnionitis is a syndrome caused by intraamniotic infection, sterile intraamniotic inflammation (inflammation without bacteria), or systemic maternal inflammation induced by epidural analgesia...

Objective: To investigate the clinical characteristics of induced labor in twin pregnancy and the related factors of induced labor failure. Methods: The clinical data of twin pregnant women who underwent induced labor in Peking University Third Hospital from January 2016 to December 2022 were retrospectively analyzed. According to whether they had labor or not after induction, pregnant women were divided into the success group (pregnant women who had labor after induction, 72 cases) and the failure group (pregnant women who did not have labor after induction, 30 cases)...

KEY CLINICAL MESSAGE: Considering the laceration of the inner layer of the myometrium as an important and controllable cause of bleeding during childbirth can lead to saving the mother's life. ABSTRACT: Laceration of the inner layer of the myometrium can cause massive bleeding during and after childbirth, which can lead to the death of the mother if it is not diagnosed in time.we presented a rare case of massive intrapartum bleeding following myometrial laceration that diagnosed correctly and the patient survived with in-time treatments...

INTRODUCTION: In 2017, the French national authority for health issued national guidelines to support physiologic labor and reduce medical interventions. This study's primary aim was to evaluate the association between the publication of these guidelines and the vaginal delivery rate in a type IIb perinatal center. The secondary objectives were to evaluate the implementation of these guidelines, their association with the duration of labor, and the rates of postpartum hemorrhage and adverse neonatal outcomes...

OBJECTIVE: To evaluate efficacy in achieving vaginal delivery with a standardized vaginal compared with oral misoprostol regimen for labor induction at term. METHODS: In this single-center, cluster randomized trial, we randomized induction method by week among individuals with gestational age of 37 weeks or more, cervical dilation of 2 cm or less, intact membranes, and indication for delivery to either oral (100 micrograms every 4 hours for up to two doses), or vaginal (25 micrograms every 3 hours for up to five doses) misoprostol regimens, followed by a standardized oxytocin protocol...

BACKGROUND: Oxytocin is considered the drug of choice for the induction of labor, although the optimal protocol and infusion duration remain to be determined. OBJECTIVE: This study aimed to assess whether the duration of oxytocin infusion increases 24-hour delivery rates and affects the length of time-to-delivery and patient's experience. STUDY DESIGN: A randomized controlled trial was performed at a single tertiary medical center, between January 1, 2020 and June 30, 2022...

BACKGROUND: In 2014, the National University Hospital of Iceland (NUHI) merged a mixed-risk birth unit and a midwifery-led low-risk unit into one mixed-risk unit. Interprofessional preventative and mitigating measures were implemented since there was a known threat of cultural contamination between mixed-risk and low-risk birth environments. The aim of the study was to assess whether the NUHI's goal of protecting the rates of birth without intervention had been achieved and to support further development of labor services...

OBJECTIVE: The benefit of mechanical ripening agents following preterm premature rupture of membranes (PPROM) has not been established. We sought to compare the time to delivery in women who received transcervical Foley catheter plus oxytocin infusion versus oxytocin infusion alone in patients with unfavorable cervices and preterm rupture of membranes (PPROM). STUDY DESIGN: This is a retrospective cohort study of patients presenting with PPROM of a live, singleton gestation between 24 0/7 and 36 6/7 weeks gestation from January 2005 to October 2018 at a single, tertiary care institution...

BACKGROUND: The management and nursing care of women's temperature during delivery is an important part of clinical obstetrics. We aimed to evaluate maternal intrapartum fever during epidural labour analgesia to provide evidence for the management and care of women in labour. METHODS: This study was conducted and reported according to the STROBE statement. Women in labour undergoing epidural labour analgesia in our hospital from 1 January 2021 to 31 August 2022 were retrospectively selected...

BACKGROUND: The underlying mechanism of epidural-related maternal fever (ERMF) is not fully understood. This systematic review aimed to identify factors associated with ERMF in low-risk, full-term women using neuraxial analgesia. METHODS: PubMed, Embase, Web of Science, CENTRAL, and Wanfang Data were searched from inception to September 10, 2022 with no language restriction. Studies reported descriptive data regarding the factors associated with ERMF. A random effects model meta-analysis was used to pool the raw data of univariate analyses for each identified factor...

Aims and Objectives To compare the safety and efficacy of dinoprostone pessary with Foley plus vaginal misoprostol for cervical ripening. Materials and Methods We randomized 115 women to the pessary or Foley plus misoprostol group. Pessary was inserted for 24 hours, and in the Foley plus misoprostol group, intravaginal misoprostol 25 mcg was administered along with trans-cervical Foley insertion and repeated every six hours to a maximum dose of 100 mcg. Singleton pregnancies requiring labor induction at more than 34 weeks with a Bishop score of <6 were included...

This study compares the effectiveness and safety of oxytocin infusion against oral misoprostol for inducing labour in pregnant women with term prelabor membrane rupture. We randomized 173 pregnant women presenting with term prelabor rupture of membranes (PROM) at Ain Shams University Maternity Hospital into Group A (underwent induction of labor (IOL) by 25μg misoprostol oral tablet every 4 h, for maximum 5 doses) and an identical Group B: (underwent IOL by oxytocin infusion according to the hospital protocol)...

BACKGROUND: Misoprostol is widely used for cervical ripening and labour induction as it is heat-stable and inexpensive. Oral misoprostol 25 μg given 2-hourly is recommended over vaginal misoprostol 25 μg given 6-hourly, but the need for 2-hourly fetal monitoring makes oral misoprostol impractical for routine use in high-volume obstetric units in resource-constrained settings. OBJECTIVES: To compare the efficacy and safety of oral misoprostol initiated at 25 or 50 μg versus 25 μg vaginal misoprostol given at 4- to 6-hourly intervals for labor induction in women at or beyond term (≥ 37 weeks) with a single viable fetus and an unscarred uterus...

OBJECTIVE: To evaluate the rates of cesarean delivery in patients with prolonged labor randomized to receive intravenous (IV) propranolol compared with placebo. METHODS: A double-blind, placebo-controlled, randomized trial was conducted at two hospitals within a large academic health system. Eligible patients were at 36 weeks or more with a singleton gestation and prolonged labor , defined as: 1) prolonged latent phase of labor (dilation less than 6 cm after 8 hours or more with ruptured membranes and receiving oxytocin infusion) or 2) prolonged active phase of labor (dilation 6 cm or greater and less than 1-cm cervical dilation change over 2 hours or more with ruptured membranes and receiving oxytocin infusion)...

OBJECTIVE: Term prelabour rupture of membrane (PROM) occurs in 8% of term deliveries, but it is unclear when to initiate induction. Our objective was to assess the optimal timing of oxytocin induction in the management of term PROM in terms of maternal and neonatal outcomes. METHODS: A retrospective cohort study was performed at a single tertiary care center from 2010 to 2020. All singleton pregnancies with PROM beyond 37 weeks gestation, without regular uterine contractions, were included...

OBJECTIVE: Epidural analgesia has been widely used as a form of pain relief during labor and its safety has been gradually recognized. However, few studies of the effect of epidural analgesia on the pelvic floor are known. Thus, we aim to analyze the effect of epidural analgesia on labor progress and women's pelvic floor muscle from the perspective of electromyography systematically. In addition, obstetric risk factors for dysfunction of pelvic floor muscle after vaginal delivery were also evaluated...

OBJECTIVES: To compare the effectiveness and safety of Dinoprostone Gel (DG), Misoprostol Vaginal Insert (MVI) and Dinoprostone Vaginal Insert (DVI) for induction of labour (IOL) in twin pregnancies. STUDY DESIGN: Retrospective cohort study of twin pregnancies > 34 + 0 weeks gestation that underwent induction of labour (IOL) with DG, MVI or DVI between December 2016 and November 2019 in a Tertiary NHS hospital, North West England, UK...

BACKGROUND: Breech presentation at term can cause complications during birth and increase the chance of caesarean section. Moxibustion (a type of Chinese medicine which involves burning a herb close to the skin) at the acupuncture point Bladder 67 (BL67) (Chinese name Zhiyin), located at the tip of the fifth toe, has been proposed as a way of changing breech presentation to cephalic presentation. This is an update of a review first published in 2005 and last published in 2012. OBJECTIVES: To examine the effectiveness and safety of moxibustion on changing the presentation of an unborn baby in the breech position, the need for external cephalic version (ECV), mode of birth, and perinatal morbidity and mortality...
