BACKGROUND: The optimal method for induction of labor for multiparous women with an unfavorable cervix is unknown. OBJECTIVE: To determine if induction of labor with simultaneous use of oxytocin and a cervical ripening balloon, compared with sequential use, increases the likelihood of delivery within 24 hours in multiparous women. STUDY DESIGN: We performed a randomized controlled trial between November 2014 and June 2017. Eligible participants were multiparous women with a vertex presenting, non-anomalous singleton gestation ≥ 34 weeks undergoing induction of labor...

OBJECTIVE: To determine whether cervical ripening with misoprostol (MP) is associated with higher rates of cesarean delivery (CD) (CD) compared to dinoprostone (DP) or Pitocin/Foley balloon (PFB) in infants found to be small for gestational age (SGA). STUDY DESIGN: Single center institution based cohort study of all inductions between 2008-2012 where birth weight was found to be as SGA (< 10th percentile). Maternal demographic, obstetric, and labor characteristics were compared between SGA births where cervical ripening with MP, Mode compares MP to referent group (DP), or PFB was used as the primary agent...

The time of birth is a critical determinant of perinatal and long-term outcomes. Preterm birth is still the first cause of infant mortality and morbidity; unfortunately, rates of preterm birth remain high in both high- and low-resource countries, ranging from 5% to 18%. Preterm parturition is a syndrome, which can be induced by various factors such as infection, cervical pathology, uterine overdistension, progesterone deficiency, vascular alterations (utero-placental ischemia, decidual hemorrhage), maternal and fetal stress, allograft reaction, allergic phenomena, and probably other several unknown factors...

A 22-year-old woman, G3P0 at 31 weeks, 1 day gestational age, was admitted to the labor and delivery unit for induction of labor (IOL) due to preeclampsia with severe features. Her medical history included neurofibromatosis type 1 (NF-1) and systemic lupus erythematosus with pericarditis and pericardial effusion. When labor analgesia was considered, the concern for an undiagnosed spinal neurofibroma and attendant sequelae was deliberated. After a multidisciplinary discussion, the IOL was halted during the cervical ripening phase to allow timely magnetic resonance imaging (MRI) of the spine...

Labor is defined as contractions with cervical change and active labor starts when the cervix is dilated 6 cm. Updated labor curves and definitions should be used to define labor dystocia. Oxytocin and amniotomy have important roles in the management of labor dystocia. Structured intermittent fetal monitoring should be considered for women with low-risk pregnancies but continuous electronic fetal monitoring still is used most commonly. Moderate fetal heart rate variability is the most reliable marker of fetal well-being...

INTRODUCTION: Induction of labor is a common intervention. The objective was to investigate whether larger Foley catheter volumes for labor induction decrease the total time from induction to delivery. MATERIAL AND METHODS: Randomized controlled trials comparing larger single-balloon volumes (60-80 mL) during Foley catheter cervical ripening with usual volume (30 mL) in women undergoing labor induction were identified by searching electronic databases (MEDLINE, Scopus, ClinicalTrials...

The prediction of successful labour induction is difficult, indicating a need for a biomarker test. Little is known about the effect of Foley catheter (FC) induction on biochemical mediators in the cervix, such as the insulin-like growth factor binding protein-1 (IGFBP-1), matrix metalloproteinases (MMP) and their inhibitors (TIMP). We enrolled 35 nulliparous women with singleton pregnancies, intact amniotic membranes and cephalic presentation ≥40 gestational weeks scheduled for labour induction by FC. Serial cervical swab samples were collected at FC insertion and expulsion...

This study was designed to evaluate the application effect of single balloon catheters and dinoprostone on promoting cervical ripening of pregnant women in late-term pregnancy and their influences on stress and inflammatory responses. A total of 160 pregnant women with indications of labor induction were included and randomly divided into the control (n=80) and observation (n=80) groups. Patients in the control group received labor induction by administration of dinoprostone at the vaginal vault, while those in the observation group received labor induction by domestic single balloon catheters...

BACKGROUND: Hospital electronic health record (EHR) data are increasingly being called upon for research purposes, yet only recently has it been tested to examine its reliability. Studies that have examined reliability of EHR data for research purposes have varied widely in methods used and field of inquiry, with little reporting of the reliability of perinatal and obstetric variables in the current literature. OBJECTIVE: To assess the reliability of data extracted from a commercially available inpatient EHR as compared with manually abstracted data for common attributes used in obstetrical research...

The peptide hormone relaxin has numerous roles both within and independent of pregnancy and is often thought of as a 'pleiotropic hormone'. Relaxin targets several tissues throughout the body, and has many functions associated with extracellular matrix remodeling and the vasculature. This review considers the potential therapeutic applications of relaxin in cervical ripening, in vitro fertilization, preeclampsia, acute heart failure, ischemia-reperfusion and cirrhosis. We first outline the animal models used in preclinical studies to progress relaxin into clinical trials and then discuss the findings from these studies...

BACKGROUND: It has been suggested that cervical ripening with a balloon catheter for labour induction can be done in an outpatient setting in low-risk pregnancies. Introduction of such an approach needs to be accompanied with monitoring of potential complications. Therefore the existence and frequency of any associated adverse event during cervical ripening needs to be established. OBJECTIVE: To assess the complication rate during cervical ripening with balloon induction...
