BACKGROUND: While there are well-accepted standards for the diagnosis of arrested active-phase labor, the definition of a "failed" induction of labor remains less certain. One approach to diagnosing a failed induction is based on the duration of the latent phase. However, a standard for the minimum duration that the latent phase of a labor induction should continue, absent acute maternal or fetal indications for cesarean delivery, remains lacking. OBJECTIVE: The objective of this study was to determine the frequency of adverse maternal and perinatal outcomes as a function of the duration of the latent phase among nulliparous women undergoing labor induction...

OBJECTIVE: To examine whether racial and ethnic differences exist in the frequency of and indications for cesarean delivery and to assess whether application of labor management strategies intended to reduce cesarean delivery rates is associated with patient's race and ethnicity. METHODS: This is a secondary analysis of a multicenter observational obstetric cohort. Trained research personnel abstracted maternal and neonatal records of greater than 115,000 pregnant women from 25 hospitals (2008-2011)...

BACKGROUND: Pregnant women with pulmonary hypertension (PH) are at risk for adverse cardiac outcomes, particularly at the time of labor and delivery. The purpose of this study is to define the impact of PH on pregnancy outcomes and the risk of major adverse cardiac events (MACE). METHODS AND RESULTS: The National Inpatient Sample was screened for hospital admissions of women delivering during the years 2003 to 2012. The primary outcome was MACE, a composite of death, cardiac arrest, cardiogenic shock, myocardial infarction, respiratory failure, arrhythmia, stroke, and embolic event...

PURPOSE: A model exists that predicts the probability of vaginal birth after cesarean (VBAC). That model is not stratified by indication at first cesarean. The aim of the study was to identify factors that may predict successful VBAC in patients operated for arrest of dilatation or descent at their first cesarean. METHODS: Retrospective analysis of all women with trials of labor after one cesarean (TOLAC) for non-progressive labor between November 2008 and October 2015 was performed (n = 231)...

BACKGROUND: In 2010 the Consortium on Safe Labor published labor curves. It was proposed that the rate of cesarean delivery could be lowered by avoiding the diagnosis of arrest of dilation before 6 cm. However, there is little information on the uptake of the guidelines and on changes in cesarean delivery rates that may have occurred. OBJECTIVE: The objective of the study was to test the following hypotheses: (1) among patients laboring at term, rates of arrest of dilation disorders have decreased, leading to a decrease in the rate of cesarean delivery; (2) in the second stage, pushing duration prior to diagnosis of arrest of descent has increased, also leading to a reduction in the rate of cesarean delivery for this indication...

OBJECTIVE: To examine whether labor compared with planned cesarean delivery is associated with increased maternal and neonatal morbidity. METHODS: We conducted a retrospective cohort study of all women with body mass indexes (BMIs) at delivery of 50 or greater delivering a live fetus at 34 weeks of gestation of greater between January 1, 2008, and December 31, 2015. Pregnancies with multiple gestations and major fetal anomalies were excluded. The primary outcome was a composite of maternal and neonatal morbidity and was estimated to be 50% in superobese women based on institutional data...

BACKGROUND: Extreme ambient temperatures are linked to cardiac events in the general population, but this relationship is unclear among pregnant women. We estimated the associations and attributable risk between ambient temperature and the risk of cardiovascular event at labor/delivery, and investigated whether these associations vary by maternal race/ethnicity. METHODS: We identified 680 women with singleton deliveries affected by cardiovascular events across 12 US sites (2002-2008)...

State laws are awash with discord concerning whether a police officer's request or court order necessarily obligates physicians to perform a body fluid analysis of an arrested, conscious, nonconsenting suspect. Police typically bring arrestees directly to the emergency department (ED), and federal courts have begun to wrestle with the implications of the Emergency Medical Treatment and Labor Act (EMTALA), which requires that anyone presenting to the ED be screened for treatment. Some state laws require health care providers to comply with any police request for lab analysis, while other states offer more leeway to physicians...

BACKGROUND: Progesterone may be effective in prevention of premature birth in some high risk populations. Women with arrested premature labor are at risk of recurrent labor and maintenance therapy with standard tocolytics has not been successful. METHODS: Randomized double blinded clinical trial of daily treatment with 200 mg vaginal progesterone in women with arrested premature labor and an updated meta-analysis. RESULTS: The clinical trial was terminated early after 41 women were enrolled...

BACKGROUND Capnocytophaga ochracea is a gram-negative anaerobic organism commonly found in human oral flora. It is characteristically sensitive to beta-lactams and resistant to aminoglycosides. CASE REPORT A 23-year-old woman presented with lower abdominal pain and was admitted for premature labor at 24-weeks of gestation. At presentation, the cervix was closed and the membrane was intact; however, contractions continued, the membrane subsequently ruptured before receiving any steroids or magnesium, and the mother gave birth to a 540-gram female baby...

BACKGROUND: Approximately one third of all deliveries in the United States are via cesarean. Previous research indicates weight gain during pregnancy is associated with an increased risk of cesarean delivery. It remains unclear, however, whether and to what degree weight gain between deliveries (ie, interdelivery weight gain) is associated with cesarean delivery in a subsequent pregnancy following a vaginal delivery. OBJECTIVES: The objective of the study was to determine whether interdelivery weight gain is associated with an increased risk of intrapartum cesarean delivery following a vaginal delivery...
