BACKGROUND: We aimed to describe the length of second stage of labor in a contemporary cohort. We calculated the 5th, 50th, and 95th percentiles for second-stage length stratified by parity and epidural analgesia use and evaluated the effect of labor induction and oxytocin augmentation in our cohort. METHODS: We did a retrospective analysis of all live, singleton, term vaginal deliveries in one tertiary hospital. Multivariate linear regression was used to evaluate second-stage duration confounders...

INTRODUCTION: An increasing proportion of nulliparous women are over 40 years and labor is more often induced. The aim of this study was to assess delivery outcome in women over 40 years, accounting for the interaction between age and induction. MATERIAL AND METHODS: Population-based study of 1 644 598 nulliparous women with live singleton cephalic term deliveries 1992 to 2011. Risks of intrapartum cesarean section, operative vaginal delivery, obstetric anal sphincter injury (OASIS), and 5-minutes Apgar score <7 were calculated in women ≥40 years with induced or spontaneous labor, and women <40 years with induced labor by unconditional logistic regression, and presented with crude and adjusted odds ratios (aOR) with 95% confidence intervals (95%CI)...

BACKGROUND: Neuraxial anesthesia is considered as the gold standard in the control labor of pain. Its variants are epidural analgesia and combined spinal-epidural analgesia. Few studies, as yet, have investigated the duration of labor as a primary outcome. Some authors have suggested that combined spinal-epidural analgesia may reduce labor duration but at the moment the benefit of shortening labor is uncertain. The main aim of this study was to compare combined spinal-epidural with epidural analgesia in terms of their effect on duration of stage I labor, maternal, and neonatal outcomes...

INTRODUCTION: Infections are a leading cause of mortality and morbidity in preschool children. We aimed to assess the impact of the co-occurrence of cesarean section, early birth and formula feeding on hospitalization with infection in early childhood. MATERIAL AND METHODS: Population-based retrospective record-linkage cohort study of 488 603 singleton livebirths ≥32 weeks gestational age in New South Wales, Australia, 2007-2012. Multivariable Cox-regression was used to estimate independent and combined adjusted associations of gestational age, mode of birth (vaginal or cesarean section by labor onset) and formula feeding with time to first and repeat hospitalization with infection for children <5 years of age...

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...

A 36-year-old pregnant woman with a history of rheumatic heart disease and prior aortic valve replacement and mitral valve repair presented to an outside hospital with severe aortic stenosis. The patient had a cardiac arrest upon labor induction and underwent a transcatheter aortic valve replacement (TAVR), which dislodged two days later. Five months later, the patient underwent removal of the dislodged TAVR and a Ross procedure at the authors' institution. The patient was stable upon discharge, with minimal aortic and pulmonary regurgitation...

REVIEW
Kate F Walker, Jim G Thornton
There is growing evidence from randomized trials that induction of labor at or near term does not increase cesarean delivery; observational data show that the optimal gestation for spontaneous delivery for the baby is 39 weeks. Elective cesarean at these gestations is also sometimes considered, but evaluating the associated risks is complex. For the baby, although cesarean obviates the risks of labor, it carries a risk of respiratory problems, which may be severe. For the mother, cesarean is more dangerous than vaginal and emergency cesarean is more dangerous than elective...

BACKGROUND: Misoprostol vaginal insert for induction of labor has been recently reported to be superior to dinoprostone vaginal insert in a phase III trial, but has never been compared to vaginal misoprostol in another galenic form. The aim of this study was to compare misoprostol vaginal insert (MVI) with misoprostol vaginal tablets (MVT) for induction of labor in term pregnancies. METHODS: In this retrospective cohort study we compared 200 consecutive women induced with 200-μg misoprostol 24-h vaginal insert (Misodel®) with a historical control of 200 women induced with Misoprostol 25-μg vaginal tablets (Cytotec®) every 4-6 h...

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...

OBJECTIVE: To evaluate the outcomes of vacuum-assisted vaginal deliveries (VAD) among neonates of mothers with gestational diabetes mellitus (GDM). STUDY DESIGN: Retrospective cohort study of women with singleton gestation ≥37 + 0 weeks of gestation who underwent VAD at a single, tertiary, medical center (2007-2014). Women with GDM and their neonates were compared to women without diabetes and their neonates. Composite neonatal outcome was defined as ≥1 of the following: shoulder dystocia, 5-min Apgar score <7, asphyxia, seizure, subgaleal, subarachnoid or subdural hemorrhage, fracture of the clavicle, humerus or skull, or Erb's palsy...

Amniotic fluid embolism (AFE) is a rare but fatal obstetric emergency, which is characterized by a sudden cardiovascular collapse, respiratory failure, and disseminated intravascular coagulation (DIC). We report a case of sudden cardiac arrest due to an amniotic-fluid embolism which was successfully treated with veno-arterial extracorporeal membrane oxygenation (ECMO). A 32-year-old female at 39.1 weeks of gestation was scheduled for induction labor. During labor, a sudden generalized tonic-clonic seizure was developed followed by dyspnea and hypotension...

Labor induction is a common practice to promote uterine contractions and labor onset. Uterine electrohysterogram (EHG) has proved its suitability for characterizing the uterus electrophysiological condition in women with spontaneous labor. The aim of this study was to characterize and compare uterine myoelectrical activity during the first 4 h in response to labor induction drugs, Misoprostol (G1) and Dinoprostone (G2), by analyzing the differences between women who achieved active phase of labor and those who did not (successful and failed inductions)...

OBJECTIVE: Optimal management of pregnancies at 39 weeks gestational age is unknown. Therefore, we sought to perform a comparative effectiveness analysis of elective induction of labor (eIOL) at 39 weeks among nulliparous women with non-anomalous singleton, vertex fetuses as compared to expectant management (EM) which included IOL for medical or obstetric indications or at 41 weeks in undelivered mothers. MATERIALS AND METHODS: A Monte Carlo micro-simulation model was constructed modeling two mutually exclusive health states: eIOL at 39 weeks, or EM with IOL for standard medical or obstetrical indications or at 41 weeks if undelivered...

BACKGROUND: Population data on obstetric interventions is often limited to cesarean delivery. We aimed to provide a more comprehensive overview of trends in use of several common obstetric interventions over the past 2 decades. METHODS: The study was based on nationwide data from the Icelandic Medical Birth Register. Incidence of labor induction, epidural analgesia, cesarean, and instrumental delivery was calculated for all births in 1995-2014. Change over time was expressed as relative risk (RR), using Poisson regression with 95% confidence intervals (CI) adjusted for several maternal and pregnancy-related characteristics...

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...

Early initiation of prenatal care is associated with improved health outcomes for women and newborns. An essential element of prenatal care is determining the estimated due date, ideally using a first-trimester ultrasound. Laboratory tests should be obtained to screen for conditions that can affect pregnancy. Routine immunizations for all pregnant women include influenza vaccine; tetanus toxoid, reduced diphtheria, acellular pertussis (Tdap) vaccine. All women should be screened for gestational diabetes mellitus in midpregnancy...
