OBJECTIVE To evaluate severe maternal morbidity (SMM) among patients with epilepsy and patients without epilepsy. METHODS We retrospectively examined SMM using linked birth certificate and maternal hospital discharge records in California between 2007 and 2012. Epilepsy present at delivery admission was the exposure and was subtyped into generalized, focal and other less specified, or unspecified. The outcomes were SMM and nontransfusion SMM from delivery up to 42 days' postpartum, identified using Centers for Disease Control and Prevention indicators. Multivariable logistic regression models were used to adjust for confounders, which were selected a priori. We also estimated the association between epilepsy and SMM independent of comorbidities by using a validated obstetric comorbidity score. Severe maternal morbidity indicators were then compared using the same multivariable logistic regression models. RESULTS Of 2,668,442 births, 8,145 (0.3%) were to patients with epilepsy; 637 (7.8%) had generalized, 6,250 (76.7%) had focal or other less specified, and 1,258 (15.4%) had unspecified subtypes. Compared with patients without epilepsy, patients with epilepsy had greater odds of SMM (4.3% vs 1.4%, adjusted odds ratio [aOR] 2.91, 95% CI 2.61-3.24) and nontransfusion SMM (2.9% vs 0.7%, aOR 4.16, 95% CI 3.65-4.75). Epilepsy remained significantly associated with increased SMM and nontransfusion SMM after additional adjustment for the obstetric comorbidity score, though the effects were attenuated. When grouped by organ system, all SMM indicators were significantly more common among patients with epilepsy-most notably those related to hemorrhage and transfusion. CONCLUSION Severe maternal morbidity was significantly increased in patients with epilepsy, and SMM indicators across all organ systems contributed to this.

Background There are few data regarding safety of pregnancy after uterine artery embolization. However, numerous women desire future fertility after this procedure. Uterine rupture without a history of cesarean delivery or uterine scarring is an exceedingly rare complication in pregnancy. Case We report a case of uterine rupture in a primigravid woman after uterine artery embolization. Her pregnancy was also complicated by placenta previa with placenta increta, resulting in a favorable neonatal outcome in an otherwise life-threatening situation for mother and fetus. Conclusion Uterine artery embolization is a risk factor for abnormal placentation and uterine rupture in subsequent pregnancies.

To compare the efficacy and side effects of intravenous magnesium to oral nifedipine for acute tocolysis of preterm labor.A multicenter randomized trial was performed. Patients in active preterm labor who were at 24 to 33 weeks and 6 days of gestation were randomly assigned to receive magnesium sulfate or nifedipine. The primary outcome was arrest of preterm labor, defined as prevention of delivery for 48 hours with uterine quiescence.One hundred ninety-two patients were enrolled. More patients assigned to magnesium sulfate achieved the primary outcome (87% compared with 72%, P=.01). There were no differences in delivery within 48 hours (7.6% magnesium sulfate compared with 8.0% nifedipine, P=.92), gestational age at delivery (35.8 compared with 36.0 weeks, P=.61), birth before 37 and 32 weeks (57% compared with 57%, P=.97, and 11% compared with 8%, P=.39), and episodes of recurrent preterm labor. Mild and severe maternal adverse effects were significantly more frequent with magnesium sulfate. Birth weight, birth weight less than 2,500 g, and neonatal morbidities were similar between groups, but newborns in the magnesium sulfate group spent longer in the neonatal intensive care unit (8.8+/-17.7 compared with 4.2+/-8.2 days, P=.007).Patients who received magnesium sulfate achieved the primary outcome more frequently. However, delay of delivery, gestational age at delivery, and neonatal outcomes were similar between groups. Nifedipine was associated with fewer maternal adverse effects.

Objective To investigate current patterns of training and competency assessment in electronic fetal monitoring (EFM) for obstetrics and gynecology residents and maternal–fetal medicine fellows. Methods A questionnaire was mailed to the directors of all 254 accredited US residencies in obstetrics and gynecology and 61 accredited US fellowships in maternal–fetal medicine. Questions focused on the methods used for teaching and assessing competency in EFM. Results Two hundred thirty-nine programs (76%) responded to the survey. Clinical experience is used by 219 programs (92%) to teach EFM, both initially and on an ongoing basis. Significantly more residencies than fellowships use written materials and lectures to teach EFM. More than half of all programs require trainees to participate in some type of EFM training at least every 6 months; 23 programs (10%) have no requirement at all. Subjective evaluation is used by 174 programs (73%) to assess competency in EFM. Written or oral examinations, skills checklists, and logbooks are used exclusively by residencies as means of competency assessment. Two thirds of all programs assess EFM skills at least every 6 months; 40 programs (17%), the majority of which are fellowships, have no formal requirement. Conclusion Most US training programs use supervised clinical experience as both their primary source of teaching EFM and their principal competency assessment tool. Residencies are more likely to have formal instruction and assessment than are fellowships. Few programs are using novel strategies (eg, computers or simulators) in their curriculum.

Objective: To determine the cost-effective method of delivery, from society’s perspective, in patients who have had a previous cesarean. Methods: We completed an incremental cost-effectiveness analysis of a trial of labor relative to cesarean using a computerized model for a hypothetical 30-year old parturient. The model incorporated data from peer-reviewed studies, actual hospital costs, and utilities to quantify health-related quality of life. A threshold of $50,000 per quality-adjusted life-years was used to define cost-effective. Results: The model was most sensitive to the probability of successful vaginal delivery. If the probability of successful vaginal birth after cesarean (VBAC) was less than 0.65, elective repeat cesarean was both less costly and more effective than a trial of labor. Between 0.65 and 0.74, elective repeat cesarean was cost-effective (the cost-effectiveness ratio was less than $50,000 per quality-adjusted life-years), because, although it cost more than VBAC, it was offset by improved outcomes. Between 0.74 and 0.76, trial of labor was cost-effective. If the probability of successful vaginal delivery exceeded 0.76, trial of labor became less costly and more effective. Costs associated with a moderately morbid neonatal outcome, as well as the probabilities of infant morbidity occurring, heavily impacted our results. Conclusion: The cost-effectiveness of VBAC depends on the likelihood of successful trial of labor. Our modeling suggests that a trial of labor is cost-effective if the probability of successful vaginal delivery is greater than 0.74. Improved algorithms are needed to more precisely estimate the likelihood that a patient with a previous cesarean will have a successful vaginal delivery.

Background The majority of hospitalizations for H1N1 complications have been in people with high-risk comorbidities, including pregnancy. Here we describe the obstetric and critical care treatment of three patients with confirmed H1N1 influenza virus infection complicated by acute respiratory failure. Cases We describe the clinical and therapeutic courses of three patients with confirmed H1N1 2009 influenza virus infection complicating singleton, twin, and triplet gestations, each of which were complicated by respiratory failure. Conclusion These three cases illustrate that a high index of suspicion, prompt treatment, timing and mode of delivery considerations, and interdisciplinary treatment are integral to the care of pregnant patients with H1N1 influenza infections complicated by acute respiratory failure.

Objective: To compare the safety and efficacy of high-dose intravenous (IV) nitroglycerin with those of IV magnesium sulfate for acute tocolysis of preterm labor. Methods: Thirty-one women with preterm labor before 35 weeks’ gestation were assigned randomly to IV magnesium sulfate or IV nitroglycerin for tocolysis. Preterm labor was defined as the occurrence of at least two contractions in 10 minutes, with cervical change or ruptured membranes. Acute tocolysis was defined as tocolysis for up to 48 hours. Magnesium sulfate was administered as a 4-g bolus, then at a rate of 2–4 g/h. Nitroglycerin was administered as a 100-μg bolus, then at a rate of 1- to 10-μg/kg/min. The primary outcome measure was achievement of at least 12 hours of successful tocolysis. Results: Thirty patients were available for analysis. There were no significant differences in gestational age, cervical dilation, or incidence of ruptured membranes between groups at the initiation of tocolysis. Successful tocolysis was achieved in six of 16 patients receiving nitroglycerin, compared with 11 of 14 receiving magnesium sulfate (37.5 versus 78.6%, P = .033). Tocolytic failures (nitroglycerin versus magnesium sulfate) were due to persistent contractions with cervical change or rupture of previously intact membranes (five of 16 versus two of 14), persistent hypotension (four of 16 versus none of 14), and other severe side effects (one of 16 versus one of 14). Maternal hemodynamic alterations were more pronounced in patients who received nitroglycerin, and 25% of patients assigned to nitroglycerin treatment had hypotension requiring discontinuation of therapy. Conclusion: Tocolytic failures were more common with nitroglycerin than with magnesium sulfate. The hemodynamic alterations noted in patients receiving nitroglycerin, including a 25% incidence of persistent hypotension, might limit the usefulness of IV nitroglycerin for the acute tocolysis of preterm labor.

INTRODUCTION:Cesarean deliveries comprise approximately 30% of all births, many of which are scheduled. Given the labile nature of labor and delivery units, scheduled cesarean deliveries are often delayed. Our aim was to improve on-time scheduled cesarean delivery start times.METHODS:A multidiscipli

INTRODUCTION:A retrospective cohort study of patients with pyelonephritis in pregnancy and immediately postpartum was conducted. Participants delivered between 2005 and 2009 at a single university center (Lucile Packard Children's Hospital at Stanford) were reviewed. Pyelonephritis was defined by a
