At the same time as survival is increasing among premature babies born before 26 weeks of gestation, the rates of cesarean deliveries before 26 weeks is also rising. Our purpose was to compare the frequency of intraoperative adverse events during cesarean deliveries in two gestational age groups: 24-25 weeks and 26-27 weeks. This single-center retrospective cohort study included all women with cesarean deliveries performed before 28 +0 weeks from 2007 through 2015. It compared the frequency of intraoperative adverse events between two groups: those at 24-25 weeks of gestation and at 26-27 weeks. Intraoperative adverse events were a classical incision, transplacental incision, difficulty in fetal extraction (explicitly mentioned in the surgical report), postpartum hemorrhage (≥500 mL of blood loss), and injury to internal organs. A composite outcome including at least one of these events enabled us to analyze the risk factors for intraoperative adverse events with univariate and multivariable analysis. Stratified analyses by the indication for the cesarean were performed. We compared 74 cesarean deliveries at 24-25 weeks of gestation and 214 at 26-27 weeks. Intraoperative adverse events occurred at higher rates in the 24-25-week group (63.5 vs. 30.8%, p cesarean. These results should help obstetricians and women making decisions about cesarean deliveries at these extremely low gestational ages. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

This study was undertaken to compare success rates of vaginal birth after cesarean (VBAC) delivery, and uterine rupture as well as maternal/perinatal outcomes between women with preterm and term pregnancies undergoing trial of labor (TOL), and to compare maternal and neonatal morbidities in those women with preterm pregnancies undergoing a TOL versus repeat cesarean delivery without labor (RCD). Prospective 4-year observational study of women with a singleton gestation and a prior cesarean delivery at 19 academic centers. Clinical characteristics, maternal complications and VBAC delivery success for those with a preterm (24(0)-36(6) weeks) TOL, preterm RCD and term TOL (> or = 37 weeks) were analyzed. Among 3119 preterm pregnancies with prior cesarean delivery, 2338 (75%) underwent a TOL. 15,331 women undergoing TOL at term were also analyzed as a control group. TOL success rates for preterm and term pregnancies were similar (72.8% vs 73.3%, P = .64). Rates of uterine rupture (0.34% vs 0.74%, P = .03) and dehiscence (0.26% vs 0.67%, P = .02) were lower in preterm compared with term TOL. Thromboembolic disease, coagulopathy and transfusion were more common in women undergoing a preterm TOL than those at term. Among women undergoing a preterm TOL, rates of uterine dehiscence, coagulopathy, transfusion, and endometritis were similar to those having a preterm RCD. After controlling for gestational age at delivery and race, neonatal outcomes such as Neonatal Intensive Care Unit (NICU) admission, intraventricular hemorrhage, sepsis, and ventilatory support were similar in both groups except for a higher rate of respiratory distress syndrome in those delivered after a TOL. The likelihood of VBAC success after TOL in preterm pregnancies is comparable to term gestations, with a lower risk of uterine rupture. Perinatal outcomes are similar with preterm TOL and RCD. TOL should be considered as an option for women undergoing preterm delivery with a history of prior cesarean

To evaluate the significance of fetal Doppler parameters in predicting adverse neonatal outcomes and the risk of cesarean delivery due to non-reassuring fetal status, in severe small for gestational age (SGA) fetuses of late preterm and term gestation. Fetal brain and umbilical artery (UmA) Doppler parameters of cerebroplacental ratio (CPR) and UmA pulsatility index (PI) were evaluated in a cohort of 184 SGA fetuses between 34 and 41 weeks gestational age, who were less than the 5th percentile. The risks of neonatal morbidities and cesarean delivery due to non-reassuring fetal status were analyzed. Univariate analysis revealed that abnormal CPR was significantly associated with cesarean delivery due to non-reassuring fetal status ( P =0.018), but not with neonatal morbidities. However, abnormal CPR did not increase the risk of cesarean delivery due to non-reassuring fetal status in multivariate logistic regression analysis. Abnormal CPR with abnormal PI of UmA was associated with low Apgar score at 1 minute ( P =0.048), mechanical ventilation ( P =0.013) and cesarean delivery due to non-reassuring fetal status ( P cesarean delivery for non-reassuring fetal status (adjusted odds ratio, 7.0; 95% confidence interval, 1.2-41.3; P =0.033), but did not increase risk of low Apgar score or mechanical ventilation in multivariate logistic regression analysis. Abnormal CPR with abnormal PI of UmA increases the risk of cesarean delivery for non-reassuring fetal status, in severe SGA fetuses of late preterm and term. Monitoring of CPR and PI of UmA can help guide management including maternal hospitalization and fetal monitoring.

Cesarean delivery is the most common and important surgical intervention in obstetric practice. Ethics provides essential guidance to obstetricians for offering, recommending, recommending against, and performing cesarean delivery. This chapter provides an ethical framework based on the professional responsibility model of obstetric ethics. This framework is then used to address two especially ethically challenging clinical topics in cesarean delivery: patient-choice cesarean delivery and trial of labor after cesarean delivery. This chapter emphasizes a preventive ethics approach, designed to prevent ethical conflict in clinical practice. To achieve this goal, a preventive ethics approach uses the informed consent process to offer cesarean delivery as a medically reasonable alternative to vaginal delivery, to recommend cesarean delivery, and to recommend against cesarean delivery. The limited role of shared decision making is also described. The professional responsibility model of obstetric ethics guides this multi-faceted preventive ethics approach. Copyright © 2017.

In 1970, the cesarean delivery rate in the United States was 5.5% and women receiving prenatal care only required the knowledge that cesarean delivery was an uncommon solution to dire obstetric emergencies. In 2008, when almost one in three women deliver by cesarean, counseling on cesarean delivery must be part of each woman's prenatal care. The content of that discussion varies based on the woman's obstetric history and the anticipated mode of delivery.
Objective: To compare the obstetric outcome in terms of risk of low birth weight, preterm delivery, cesarean section rate and anemia in primigravid adolescents and older primigravida. Study Design: Cohort study. Place and Duration of Study: Department of Obstetrics and Gynaecology, Sir Ganga Ram Hospital, Lahore, from July to December 2012. Methodology: Three hundred primigravid women presenting to department of obstetrics and gynecology of Sir Ganga Ram Hospital, Lahore, having live singleton pregnancy, including 150 adolescents (A/sup 2/ 19 years) and 150 adults (A/sup 3/ 20 years) were studied. Obstetric outcome in terms of gestational age at delivery, infant's birth weight, presence of anemia and cesarean section rate was compared between two groups. Results were analyzed using Statistical Package for Social Sciences (SPSS) version 16. Chi-square test was applied with 0.05 as level of significance. Results: The mean age of adolescent subjects was 17.3 + 1.5 years and of adults 25.6 + 3.4 years. Mean gestational age at delivery was similar in two groups (39.2 weeks and 39.4 weeks, p = 0.37). Adolescents were more likely to have a preterm delivery (11.2% vs. 4.9%, p = 0.04) and low birth weight infants (19.3% vs. 8.2%, p = 0.005) than adults. Adolescents were more likely to be anemic (46% vs. 32%, p = 0.01) than adults. However, cesarean section rate was not statistically different between two groups. Conclusion: This study showed that primiparous adolescents have significantly higher risk of adverse pregnancy outcomes such as preterm delivery, low birth weight infants and anemia as compared to adult primiparas.

Cesarean section is the most common surgery performed in the United States with over 30% of deliveries occurring via this route. This number is likely to increase given decreasing rates of vaginal birth after cesarean section (VBAC) and primary cesarean delivery on maternal request, which carries the inherent risk for intraoperative complications. Urologic injury is the most common injury at the time of either obstetric or gynecologic surgery, with the bladder being the most frequent organ damaged. Risk factors for bladder injury during cesarean section include previous cesarean delivery, adhesions, emergent cesarean delivery, and cesarean section performed at the time of the second stage of labor. Fortunately, most bladder injuries are recognized at the time of surgery, which is important, as quick recognition and repair are associated with a significant reduction in patient mortality. Although cesarean delivery is a cornerstone of obstetrics, there is a paucity of data in the literature either supporting or refuting specific techniques that are performed today. There is evidence to support double-layer closure of the hysterotomy, the routine use of adhesive barriers, and performing a Pfannenstiel skin incision versus a vertical midline subumbilical incision to decrease the risk for bladder injury during cesarean section. There is also no evidence that supports the creation of a bladder flap, although routinely performed during cesarean section, as a method to reduce the risk of bladder injury. Finally, more research is needed to determine if indwelling catheterization, exteriorization of the uterus, and methods to extend hysterotomy incision lead to bladder injury. PMID:24876830

To assess possible effects of a cesarean delivery on outcome in subsequent pregnancies. Using an historical cohort design, we analyzed 637,497 first and second births among women with two or more single births and 242,812 first, second, and third births among women with three or more single births registered in the population-based Medical Birth Registry of Norway between 1967 and 2003. Compared with a vaginal delivery at first birth, a cesarean delivery at first birth was followed, in a second pregnancy, by increased risks of preeclampsia (odds ratio [OR] 2.9 and corresponding 95% confidence interval [CI] 2.8-3.1), small for gestational age (OR 1.5; CI 1.4-1.5), placenta previa (OR 1.5; CI 1.3-1.8, placenta accreta (OR 1.9; CI 1.3-2.8), placental abruption (OR 2.0; CI 1.8-2.2), and uterine rupture (OR 37.4; CI 24.9-56.2). After excluding women with the actual complication at first birth, the corresponding ORs were, in general, lower: 1.7 (CI 1.6-1.8), 1.3 (CI 1.3-1.4), 1.4 (CI 1.2-1.7), 1.9 (CI 1.3-2.8), 1.7 (CI 1.6-1.9), and 37.2 (CI 24.7-55.9), respectively. Corresponding reduction in numbers of cesarean deliveries needed to prevent one case were 114, 56, 1,140, 3,706, 300, and 461. In third births, ORs after repeat cesarean delivery were similar to or lower than the ORs after one cesarean delivery; also here, the exclusion of women with the actual outcome in any of their previous pregnancies tended to reduce the ORs. Cesarean delivery was associated with an increased risk of complications in a subsequent pregnancy, but excess risks were reduced after excluding women with the actual complication in any of their previous births. To obtain less biased effects of cesarean delivery on subsequent pregnancies, it is important to account for obstetric history. II.

Myomectomy at the time of cesarean delivery has been traditionally discouraged. Recent literature has challenged this view. We present two cases of large subserosal fibroids that underwent removal without complication at the time of cesarean delivery. We present two patients that underwent myomectomy at the time of cesarean delivery. Case 1 had a 10 cm subserosal leiomyoma removed without complication at the time of a cesarean section for breech presentation. Case two had a fundal myoma removed without incident at the time of primary cesarean delivery for suspected macrosomia. Myomectomy at the time of cesarean section has been traditionally discouraged. Recent studies have questioned this recommendation and demonstrated no significant increase in peri-operative complications when myomectomy is performed at the time cesarean section. Further, there is added benefit in that a future procedure is avoided. Myomectomy at the time of cesarean delivery is both a safe and reasonable procedure.

Cesarean delivery accounts for nearly one-third of all births in the U.S. and contributes to an additional $38 billion in healthcare costs each year. Although Cesarean delivery has a long record of improving maternal and neonatal mortality and morbidity, increased utilization over time has yielded public health concerns and calls for reductions. Observational evidence suggests Cesarean delivery is associated with increased maternal postpartum weight, which may have significant implications for the obesity epidemic. Previous literature, however, typically does not address selection biases stemming from correlations of pre-pregnancy weight and reproductive health with Cesarean delivery. We used fetal malpresentation as a natural experiment as it predicts Cesarean delivery but is uncorrelated with pre-pregnancy weight or maternal health. We used hospital administrative data (including fields used in vital birth record) from the state of Wisconsin from 2006 to 2013 to create a sample of mothers with at least two births. Using propensity score methods, we compared maternal weight prior to the second pregnancy of mothers who delivered via Cesarean due to fetal malpresentation to mothers who deliver vaginally. We found no evidence that Cesarean delivery in the first pregnancy causally leads to greater maternal weight, BMI, or movement to a higher BMI classification prior to the second pregnancy. After accounting for correlations between pre-pregnancy weight, gestational weight gain, and mode of delivery, there is no evidence of a causal link between Cesarean delivery and maternal weight retention.

The RTI International-University of North Carolina at Chapel Hill Evidence-based Practice Center (RTI-UNC EPC) systematically reviewed the evidence on the trend and incidence of cesarean delivery (CD) in the United States and in other developed countries, maternal and infant outcomes of cesarean delivery on maternal request (CDMR) compared with planned vaginal delivery (PVD), factors affecting the magnitude of the benefits and harms of CDMR, and future research directions. We searched MEDLINE, Cochrane Collaboration resources, and Embase and identified 1,406 articles to examine against a priori inclusion criteria. We included studies published from 1990 to the present, written in English. Studies had to include comparison between the key reference group (CDMR or proxies) and PVD. A primary reviewer abstracted detailed data on key variables from included articles; a second senior reviewer confirmed accuracy. We identified 13 articles for trends and incidence of CD, 54 for maternal and infant outcomes, and 5 on modifiers of CDMR. The incidence of CDMR appears to be increasing. However, accurately assessing either its true incidence or trends over time is difficult because currently CDMR is neither a well-recognized clinical entity nor an accurately reported indication for diagnostic coding or reimbursement. Virtually no studies exist on CDMR, so the knowledge base rests chiefly on indirect evidence from proxies possessing unique and significant limitations. Furthermore, most studies compared outcomes by actual routes of delivery, resulting in great uncertainty as to their relevance to planned routes of delivery. Primary CDMR and planned vaginal delivery likely do differ with respect to individual outcomes for either mothers or infants. However, our comprehensive assessment, across many different outcomes, suggests that no major differences exist between primary CDMR and planned vaginal delivery, but the evidence is too weak to conclude definitively that differences

Cesarean delivery is being increasingly used by obstetricians for indicated deliveries in the second stage of labor. Unplanned extension of the uterine incision involving the cervix often occurs with these surgeries. Therefore, we hypothesized that cesarean delivery in the second stage of labor may increase the rate of subsequent spontaneous premature birth. We sought to determine if cesarean delivery in the late first stage of labor or in the second stage of labor increases the risk of a subsequent spontaneous preterm birth. We conducted a retrospective cohort study of matched first and second births from a large Canadian perinatal database. The primary outcomes were spontaneous premature birth cesarean delivery. The protocol and analysis plan was registered prior to obtaining data at Open Science Foundation. In total, 189,021 paired first and second births were identified. The risk of spontaneous preterm delivery cesarean delivery in the second stage of labor (relative risk, 1.57; 95% confidence interval, 1.43-1.73 and relative risk, 2.12; 95% confidence interval, 1.67-2.68, respectively). The risk of perinatal death in the second birth, excluding congenital anomalies, was also correspondingly increased (relative risk, 1.44; 95% confidence interval, 1.05-1.96). Cesarean delivery in second stage of labor was associated with a 2-fold increase in the risk of spontaneous preterm birth <32 weeks of gestation in a subsequent birth. This information may inform management of operative delivery in the second stage. Copyright © 2017 Elsevier Inc. All rights reserved.

Studies have shown that cesarean delivery is associated with fewer subsequent births relative to vaginal delivery, but it is unclear whether confounding by pregnancy intention or indication for surgery explained these results. We evaluated the association between cesarean delivery and subsequent fecundability among 910 primiparous women after singleton live birth. In a cohort of Danish women planning pregnancy (2007-2012), obstetrical history was obtained via registry linkage; time-to-pregnancy and covariate data were collected via questionnaire. Fecundability ratios (FRs) and 95% confidence intervals (CIs) were adjusted for potential confounders. Relative to spontaneous vaginal delivery, emergency cesarean delivery with cephalic presentation showed little association with fecundability (FR = 1.0, 95% CI = 0.83, 1.3), but cesarean delivery with breech presentation (FR = 0.72, 95% CI = 0.53, 0.97) and planned cesarean delivery with cephalic presentation (FR = 0.51, 95% CI = 0.25, 1.0) were associated with reduced fecundability. The cesarean-fecundability association varied by previous fetal presentation and emergency status.

This study was undertaken to compare clinical outcomes in women with 1 versus 2 prior cesarean deliveries who attempt vaginal birth after cesarean delivery (VBAC) and also to compare clinical outcomes of women with 2 prior cesarean deliveries who attempt VBAC or opt for a repeat cesarean delivery. We performed a secondary analysis of a retrospective cohort study, in which the medical records of more than 25,000 women with a prior cesarean delivery from 16 community and tertiary care hospitals were reviewed by trained nurse abstractors. Information on demographics, obstetric history, medical and social history, and the outcomes of the index pregnancy was obtained. Comparisons of obstetric outcomes were made between women with 1 versus 2 prior cesarean deliveries, and also between women with 2 prior cesarean deliveries who opt for VBAC attempt versus elective repeat cesarean delivery. Both bivariate and multivariate techniques were used for these comparisons. The records of 20,175 women with one previous cesarean section and 3,970 with 2 prior cesarean sections were reviewed. The rate of VBAC success was similar in women with a single prior cesarean delivery (75.5%) compared with those with 2 prior cesarean deliveries (74.6%), though the odds of major morbidity were higher in those with 2 prior cesarean deliveries (adjusted odd ratio[OR] = 1.61 95% CI 1.11-2.33). Among women with 2 prior cesarean deliveries, those who opt for a VBAC attempt had higher odds of major complications compared with those who opt for elective repeat cesarean delivery (adjusted OR = 2.26, 95% CI 1.17-4.37). The likelihood of major complications is higher with a VBAC attempt in women with 2 prior cesarean deliveries compared with those with a single prior cesarean delivery. In women with 2 prior cesarean deliveries, while major complications are increased in those who attempt VBAC relative to elective repeat cesarean delivery, the absolute risk of major complications remains low.

Full Text Available ABSTRACT Objective: to identify the validity of trial of labor in women with second pregnancy and previous cesarean section, to observe vaginal deliverance and probable maternal and perinatal complications. Methods: prospective cohort study of labors (03/2010 - 03/2011. The dependent variables analyzed: vaginal delivery or cesarean section, puerperal and perinatal results complications. The control variables were: epidemiological data, previous maternal and perinatal history, maternal and fetal wellness, labor induction, weekly day and hour of labor, moment of information and birth justification to the patient. The statistical comparison used the chi-squared test with 5% significance and the program Statistical Package for Social Sciences. Results: significance in steady union and married women for cesareans sections, and single in vaginal births (p = 0.004; complete membranes were significant in cesareans sections and rupture of them to vaginal deliveries (p = 0,.001. There was a predominance of cesareans sections during 12:01 - 24:01 hours, and vaginal births from 00:01 - 6:00 hours (p = 0.036. There were no significant events in maternal and fetal complications. Newborns of c-sections were significantly heavier (p = 0.011; extra-uterine vital conditions of 1 and 5 minutes presented no difference between cesarean sections and vaginal births. Conclusion: the trial of labor in 80 patients with second pregnancy and one previous cesarean section avoided the second cesarean section in 42,5% in this patients. The results confirm that trial of labor should be stimulated to labor patients with second pregnancy and one previous cesarean section.

Full Text Available Background/Aim. Preterm birth is the leading cause of neonatal mortality. Periventricular hemorrhage-intraventricular hemorrhage (PVH-IVH remains a significant cause of both morbidity and mortality in infants prematurely born. The aim of the study was to evaluate the perinatal outcome regarding IVH of premature babies according to the mode of delivery. Methods. A total of 126 women in preterm singleton pregnancies with vertex presentation and 126 neonates weighted from 750 g to 1,500 g at birth were enrolled. The outcomes of 64 neonates born vaginally were compared to 62 neonates born by cesarean section. Results. There was no significant difference in the incidence of IVH among both groups. Conclusion. Our data is consistent with the hypothesis that the mode of delivery does not influence IVH and consenquently perinatal outcome in preterm neonates.

This trend has prompted the emergence of a debate on the risks and benefits associated with cesarean section. The present study was designed to estimate cesarean section rates over time during the period between 2000 and 2010 in Peru and to present outcomes for each mode of delivery. This is a secondary analysis of a large database obtained from the Perinatal Information System, which includes 570,997 pregnant women and their babies from 43 Peruvian public health facilities in three geographical regions: coast, highlands, and jungle. Over 10 years, 558,901 women delivered 563,668 infants weighing at least 500 g. The cesarean section rate increased from 25.5% in 2000 to 29.9% in 2010 (26.9% average; P < 0.01. The rate of stillbirths was lower with cesarean than vaginal deliveries (P < 0.01. On the other hand, and as expected, the rates for preterm births, twin pregnancies, and preeclampsia were higher in women who delivered by cesarean section (P < 0.01. More importantly, the rate of maternal mortality was 5.5 times higher in the cesarean section group than in the vaginal delivery group. Data suggest that cesarean sections are associated with adverse pregnancy outcomes.Keywords: elective cesarean, emergency cesarean, geographical regions, cesarean rates over time, adverse outcomes, developing country
Background To determine whether patients with placenta previa who delivered preterm have an increased risk for recurrent spontaneous preterm birth. Methods This retrospective population based cohort study included patients who delivered after a primary cesarean section (n = 9983). The rate of placenta previa, its recurrence, and the risk for recurrent preterm birth were determined. Results Patients who had a placenta previa at the primary CS pregnancy had an increased risk for its recurrence [crude OR of 2.65 (95% CI 1.3-5.5)]. The rate of preterm birth in patients with placenta previa in the primary CS pregnancy was 55.9%; and these patients had a higher rate of recurrent preterm delivery than the rest of the study population (p placenta previa in the primary CS pregnancy, those who delivered preterm had a higher rate of recurrent spontaneous preterm birth regardless of the location of their placenta in the subsequent delivery [OR 3.09 (95% CI 2.1-4.6)]. In comparison to all patients with who had a primary cesarean section, patients who had placenta previa and delivered preterm had an independent increased risk for recurrent preterm birth [OR of 3.6 (95% CI 1.5-8.5)]. Conclusions Women with placenta previa, who deliver preterm, especially before 34 weeks of gestation, are at increased risk for recurrent spontaneous preterm birth regardless to the site of placental implantation in the subsequent pregnancy. Thus, strict follow up by high risk pregnancies specialist is recommended. PMID:22876799

Neonatal clavicle fracture in cesarean delivery is rare and has not been extensively studied. We performed a retrospective review of cesarean deliveries with neonatal clavicle fracture during a 12-year period. Maternal and neonatal factors as well as surgical factors related to cesarean delivery for the fracture were determined and compared to the control group to analyze their significance. Among a total 89 367 deliveries during the study period, 36 286 babies were born via cesarean section. Nineteen cases of clavicle fractures in cesarean section were identified (0.05% of total live births via cesarean section). In the analysis of maternal and neonatal risk factors, birthweight, birthweight ≥ 4000 g and maternal age were significantly associated with clavicle fracture in cesarean section. However, clavicle fractures were not correlated with the selected surgical factors such as indication for cesarean section, skin incision to delivery time and incision type of skin and uterus. Logistic regression analysis showed that birthweight was the major risk factor for clavicle fracture. Clavicle fractures complicated 0.05% of cesarean deliveries. The main risk factor related to a clavicle fracture in cesarean section was the birthweight of an infant. As reported in previous studies associated with vaginal delivery, clavicle fracture is considered to be an unavoidable event and may not be eliminated, even in cesarean delivery.

To study the heritability of preterm delivery. Women who delivered a singleton infant at less than 36 weeks of gestation were asked about their family history. Twenty-eight families were identified in which the proband had at least five first- or second-degree relatives with preterm delivery. An extensive genealogy database (GenDB) was constructed using more than 9,000 genealogy sources in the public domain (records before 1929). GenDB documents the relationships between more than 17.5 million ancestors and 3.5 million descendants of approximately 10,000 individuals who moved to Utah in the mid 1800s. This database was searched for the names, birth dates, and birthplaces of the four grandparents for each of the 28 probands. Pairwise coefficients of kinship were determined for the 93 preterm delivery grandparents identified, and for sets of 100 individuals born in the 1920s who were randomly selected from the population database. Probands had a mean of 3.3 grandparents included in this database. The average coefficient of kinship for controls was 1.5 x 10(6) (standard deviation = 0.6 x 10(6)). This measure agrees with previous calculations for the Utah population. The coefficient of kinship for familial preterm delivery grandparents was more than 50 standard deviations higher (3.4 x 10(5) [P < .001]). This study confirms the familial nature of preterm delivery. On average, gravidae randomly selected from our population are 23rd degree relatives, while these preterm delivery probands are eighth-degree relatives. A genome-wide scan using these affected families is underway.

Full Text Available Objective. To identify potential risk factors for cesarean delivery following labor induction in multiparous women at term. Methods. We conducted a retrospective case-control study. Cases were parous women in whom the induction of labor had resulted in a cesarean delivery. For each case, we used the data of two successful inductions as controls. Successful induction was defined as a vaginal delivery after the induction of labor. The study was limited to term singleton pregnancies with a child in cephalic position. Results. Between 1995 and 2010, labor was induced in 2548 parous women, of whom 80 had a cesarean delivery (3%. These 80 cases were compared to the data of 160 parous women with a successful induction of labor. In the multivariate analysis history of preterm delivery (odds ratio (OR 5.3 (95% CI 1.1 to 25, maternal height (OR 0.87 (95% CI 0.80 to 0.95 and dilatation at the start of induction (OR 0.43 (95% CI 0.19 to 0.98 were associated with failed induction. Conclusion. In multiparous women, the risk of cesarean delivery following labor induction increases with previous preterm delivery, short maternal height, and limited dilatation at the start of induction.

The cesarean delivery rate in the United States has risen steadily over the past five decades such that approximately one in three women now undergo cesarean section. The rise in repeat operations and accompanying decline in trial of labor after cesarean (TOLAC) have been major contributors to this phenomenon. The appropriate use of TOLAC continues to be a topic of interest with the recognition that most women with a history of prior cesarean are candidates for trial of labor. The NICHD MFMU ...

To compare the costs associated with adjunctive azithromycin compared with standard cefazolin antibiotic prophylaxis alone for unscheduled and scheduled cesarean deliveries. A decision analytic model was created to compare cefazolin alone with azithromycin plus cefazolin. Published incidences of surgical site infection after cesarean delivery were used to estimate the baseline incidence of surgical site infection in scheduled and unscheduled cesarean delivery using standard antibiotic prophylaxis. The effectiveness of adjunctive azithromycin prophylaxis was obtained from published randomized controlled trials for unscheduled cesarean deliveries. No randomized study of its use in scheduled procedures has been completed. Cost estimates were obtained from published literature, hospital estimates, and the Healthcare Cost and Utilization Project and considered costs of azithromycin and surgical site infections. A series of sensitivity analyses were conducted by varying parameters in the model based on observed distributions for probabilities and costs. The outcome was cost per cesarean delivery from a health system perspective. For unscheduled cesarean deliveries, cefazolin prophylaxis alone would cost $695 compared with $335 for adjunctive azithromycin prophylaxis, resulting in a savings of $360 (95% CI $155-451) per cesarean delivery. In scheduled cesarean deliveries, cefazolin prophylaxis alone would cost $254 compared with $111 for adjunctive azithromycin prophylaxis, resulting in a savings of $143 (95% CI 98-157) per cesarean delivery, if proven effective. These findings were robust to a multitude of inputs; as long as adjunctive azithromycin prevented as few as seven additional surgical site infections per 1,000 unscheduled cesarean deliveries and nine additional surgical site infections per 10,000 scheduled cesarean deliveries, adjunctive azithromycin prophylaxis was cost-saving. Adjunctive azithromycin prophylaxis is a cost-saving strategy in both unscheduled

The addition of azithromycin to standard regimens for antibiotic prophylaxis before cesarean delivery may further reduce the rate of postoperative infection. We evaluated the benefits and safety of azithromycin-based extended-spectrum prophylaxis in women undergoing nonelective cesarean section. In this trial conducted at 14 centers in the United States, we studied 2013 women who had a singleton pregnancy with a gestation of 24 weeks or more and who were undergoing cesarean delivery during labor or after membrane rupture. We randomly assigned 1019 to receive 500 mg of intravenous azithromycin and 994 to receive placebo. All the women were also scheduled to receive standard antibiotic prophylaxis. The primary outcome was a composite of endometritis, wound infection, or other infection occurring within 6 weeks. The primary outcome occurred in 62 women (6.1%) who received azithromycin and in 119 (12.0%) who received placebo (relative risk, 0.51; 95% confidence interval [CI], 0.38 to 0.68; Pazithromycin group and the placebo group in rates of endometritis (3.8% vs. 6.1%, P=0.02), wound infection (2.4% vs. 6.6%, Pazithromycin was more effective than placebo in reducing the risk of postoperative infection.

OBJECTIVE To examine physician-documented indications for cesarean delivery in order to investigate the specific indications contributing to this increase. METHODS We analyzed rates of primary and repeat cesarean delivery, including indications for the procedure, among 32,443 live births at a major academic hospital between 2003–2009. Time trends for each indication were modeled to estimate the absolute and cumulative annualized relative risk of cesarean by indication over time and the relative contribution of each indication to the overall increase in primary cesarean delivery rate. RESULTS The cesarean delivery rate increased from 26% to 36.5% between 2003 and 2009; 50.0% of the increase was attributable to an increase in primary cesarean delivery. Among the documented indications, nonreassuring fetal status, arrest of dilation, multiple gestation, pre-eclampsia, suspected macrosomia, and maternal request increased over time, while arrest of descent, malpresentation, maternal-fetal indications, and other obstetric indications (eg, cord prolapse, placenta previa) did not increase. The relative contributions of each indication to the total increase in primary cesarean rate were: Non-reassuring fetal status (32%), labor arrest disorders (18%), multiple gestation (16%), suspected macrosomia (10%), pre-eclampsia (10%), maternal request (8%), maternal-fetal conditions (5%), and other obstetric conditions (1%). CONCLUSION Primary cesarean births accounted for 50% of the increasing cesarean rate. Among primary cesareans, more subjective indications (nonreassuring fetal status and arrest of dilation) contributed larger proportions than more objective indications (malpresentation, maternal-fetal, and obstetric conditions).

We compared outcomes for neonates with forceps-assisted, vacuum-assisted, or cesarean delivery in the second stage of labor. This is a secondary analysis of a randomized trial in laboring, low-risk, nulliparous women at >or=36 weeks\\' gestation. Neonatal outcomes after use of forceps, vacuum, and cesarean were compared among women in the second stage of labor at station +1 or below (thirds scale) for failure of descent or nonreassuring fetal status. Nine hundred ninety women were included in this analysis: 549 (55%) with an indication for delivery of failure of descent and 441 (45%) for a nonreassuring fetal status. Umbilical cord gases were available for 87% of neonates. We found no differences in the base excess (P = 0.35 and 0.78 for failure of descent and nonreassuring fetal status) or frequencies of pH below 7.0 (P = 0.73 and 0.34 for failure of descent and nonreassuring fetal status) among the three delivery methods. Birth outcomes and umbilical cord blood gas values were similar for those neonates with a forceps-assisted, vacuum-assisted, or cesarean delivery in the second stage of labor. The occurrence of significant fetal acidemia was not different among the three delivery methods regardless of the indication.

To determine the maternal and perinatal outcomes at term in women with one previous cesarean delivery and with no history of vaginal birth. This is a case-control study conducted at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia, between January 1, 1999 and December 31, 2002. One hundred sixty-two women with one previous cesarean delivery and with no previous vaginal birth were compared with 324 control women. The cesarean section rate was higher in the study group 40 (24.7%) versus 23 (7.1%) in the control group and was statistically significant (phistory of vaginal delivery are considered less favorable, the vaginal birth after cesarean section success rate may be even lower if the indication for previous primary cesarean delivery was failure to progress, and may be associated with increased risk of uterine rupture. Further study is required to confirm our findings.

The Ten Group Classification System (TGCS) allows critical analysis according to the obstetric characteristics of women in labor: singleton or multiple pregnancy, nulliparous, multiparous, or multiparous with a previous cesarean delivery, cephalic, breech presentation or other malpresentation, spontaneous or induced labor, and term or preterm births. Labor outcomes associated with epidural analgesia may be different among the different labor classification groups. The aim of this study was to explore associations between epidural analgesia and cesarean delivery, and epidural analgesia and assisted vaginal delivery, in women classified using the TGCS. Slovenian National Perinatal Information System data for the period 2007-2014 were analyzed. All women after spontaneous onset or induction of labor were classified according to the TGCS, within which cesarean and vaginal assisted delivery rates were investigated (P cesarean delivery rates. Women in group 1 (nulliparous term women with singleton fetuses in cephalic presentation in spontaneous labor) with epidural analgesia had a higher cesarean delivery rate. In most TGCS groups women with epidural analgesia had higher assisted vaginal delivery rates. Epidural analgesia is associated with different effects on cesarean delivery and assisted vaginal delivery rates in different TGCS groups. Copyright © 2018. Published by Elsevier Ltd.

Cesarean deliveries are widely used in many high- and middle-income countries. This overuse both increases costs and lowers quality of care and is thus a major concern in the healthcare industry. The study first examines the impact of prenatal care utilization on cesarean delivery rates. It then determines whether socioeconomic status affects the use of prenatal care and thereby influences the cesarean delivery decision. Using exclusive French delivery data over the 2008-2014 period, with multilevel logit models, and controlling for relevant patient and hospital characteristics, we show that women who do not participate in prenatal education have an increased probability of a cesarean delivery compared to those who do. The study further indicates that attendance at prenatal education varies according to socioeconomic status. Low socioeconomic women are more likely to have cesarean deliveries and less likely to participate in prenatal education. This result emphasizes the importance of focusing on pregnancy health education, particularly for low-income women, as a potential way to limit unnecessary cesarean deliveries. Future studies would ideally investigate the effect of interventions promoting such as care participation on cesarean delivery rates.

The optimal timing of delivery in the setting of various clinical conditions and scenarios remains one of the most common questions for obstetric providers. Over the past 5-10 years, the optimal timing of delivery at term, particularly for elective repeat cesareans, has been the subject of considerable investigation and discussion. There is an increasing consensus that when women opt for an elective repeat cesarean delivery, it should be performed at term rather than preterm. The recent redefinition of the "term" period into early term (37-38 weeks), full-term (39-40 weeks), late term (41 weeks), and post term designations (≥42 weeks) underscores observed heterogeneity in outcomes following delivery at term. The American College of Obstetricians and Gynecologists currently recommends that elective repeat cesarean delivery be performed at full-term. Herein, the available data to support this recommendation regarding timing of elective repeat cesarean delivery are reviewed, including contributions from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Units (MFMU) Network.

Twin vaginal delivery presents a unique clinical challenge for obstetricians. The Twin Birth Study demonstrated the safety of planned vaginal delivery regarding neonatal outcomes. However, that study lacked a description of the risk factors associated with and the outcome of unplanned cesarean section. The aim of this study is to identify potential risk factors for cesarean section and delivery related neonatal morbidity and mortality in women with twin pregnancy attempting vaginal delivery. A retrospective cohort study including 1070 women with twin pregnancy that underwent a trial of labor between 2003 and 2015. The study population was divided according to the mode of delivery: vaginal delivery, combined vaginal-cesarean and intrapartum cesarean delivery of both twins. Several risk factors and neonatal outcomes were examined by both univariate analysis and multinomial logistic regression analysis. The rate of vaginal delivery of both twins was 88.3%, whereas the rates of combined vaginal cesarean and unplanned cesarean delivery were 4.6% and 7.1%, respectively. Nulliparity and nonvertex presentation of twin B were found to be independently associated with cesarean delivery for both twins. Additionally, nonvertex presentation of twin B was independently associated with combined vaginal-cesarean delivery. The proportion of neonates with Apgar score cesarean group compared with those delivered by the vaginal route alone. Nulliparity and nonvertex presentation of twin B were found to be associated with intrapartum cesarean delivery in twin pregnancies. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Background: Cesarean section rates have risen markedly worldwide. Considering the potential harm caused by this mode of delivery, and the general concern in reducing its incidence, it would be useful to individualize the risk of non-planned cesareans, and if there is any possibility, reduce that risk, and anesthesiologists should take part of this risk evaluation. In recent studies, many factors have been related with a higher risk of cesarean, and controversy still surrounds labor analges...

To investigate the maternal complications associated with cesarean section (CS) in the extremely preterm period according to the gestational week (GW) and to indication of delivery. This is a retrospective case-referent study with a review of medical records of women who delivered at 22-27 weeks of gestation (n=647) at two level III units in Sweden. For abdominal delivery, gestational length was stratified into 22-24 (n=105) and 25-27 (n=301) weeks. For comparison, data on women who underwent a CS at term were identified in a register-based database. The rate of CS in extremely preterm births was 62.8%. There was no difference in the complication rates, but types of incisions other than the low transverse incision were required more often at 22-24 (18.1%) weeks than at 25-27 GWs (9.6%) (P=0.02). Major maternal complications occurred in 6.6% compared with 2.1% in the extremely preterm and term CS, respectively (Pcomplications. Almost two-thirds of the births at 22-27 GWs had an abdominal delivery. No increase in short-term morbidity was observed at 22-24 weeks compared to 25-27 weeks. CS performed extremely preterm had more major complications recorded than cesarean at term. The complications are driven by the underlying maternal condition.

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. 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. As a secondary aim, we investigated changes in maternal and neonatal morbidity. This was a secondary analysis of a prospective cohort study of all patients presenting at ≥37 weeks' gestation from 2010 through 2014 with a nonanomalous vertex singleton and no prior history of cesarean delivery. Rates of cesarean delivery, arrest of dilation, and changes in rates of maternal and neonatal morbidity were calculated in crude and adjusted models. Cervical dilation at diagnosis of the arrest of dilation, time spent at the maximal dilation prior to diagnosis of arrest of dilation, and time in the second stage prior to the diagnosis of arrest of descent were compared over the study period. There were 7845 eligible patients. The cesarean delivery rate in 2010 was 15.8% and, in 2014, 17.7% (P trend = .51). In patients undergoing cesarean delivery for the arrest of dilation, the median cervical dilation at the time of cesarean delivery was at 5.5 cm in 2010 and 6.0 cm in 2014 (P trend = .94). In these patients, there was an increase in the time spent at last dilation: 3.8 hours in 2010 to 5.2 hours in 2014 (P trend = .02). There was no change in the frequency of patients diagnosed with the arrest of dilation at cesarean deliveries for the arrest of descent. The median

This study aims to examine the risk for subsequent ectopic pregnancy in women with prior cesarean delivery. Women with a history of at least one cesarean delivery in the state of Utah during 1996 to 2011 were identified and compared with women with vaginal delivery only. The primary outcome was subsequent ectopic pregnancy. Data were analyzed by multivariate logistic regression and stratified by first, second, or third live births. Model covariates included maternal age, ethnicity, marital status, education level, gravidity, and prior ectopic pregnancy. Overall, 260,249 women with at least one live birth were identified. After exclusions, 255,082, 154,930, and 70,228 women had at least one, two, and three prior live births that lead to 531, 199, and 62 subsequent ectopic pregnancies, respectively. Women who had one prior cesarean delivery were not at increased risk for subsequent ectopic pregnancy in relation to women with no prior cesarean delivery. However, women with two of two, two of three, or three of three prior cesareans had increased risk for subsequent ectopic pregnancy with odds ratios (95% confidence interval) of 1.54 (1.06-2.22), 3.50 (1.49-8.24), and 1.99 (1.00-3.98), respectively. History of two or three cesarean deliveries is associated with increased risk for subsequent ectopic pregnancy. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Persistent pain after cesarean delivery and vaginal delivery has been the subject of only a few research articles. The primary outcome of our prospective study was the incidence of persistent pain and its association to mode of delivery. We also studied the nature and intensity of pain after delivery. A questionnaire was distributed on postpartum day 2 to 1052 women who had given birth vaginally and to 502 who had undergone cesarean delivery in a tertiary maternity hospital in Helsinki, Finland, in 2010. A second questionnaire was mailed to the women 1 year later. We recorded the women's health history, obstetric history and previous pain history, details of cesarean delivery or vaginal delivery, and description of pain, if present. The incidence of persistent pain at 1 year after delivery was greater after cesarean delivery (85/379 [22%]) than after vaginal delivery (58/713 [8%]: P delivery as a predictor of persistent pain. The incidence of persistent pain graded as moderate or more severe (25/379 [7%] vs 25/713 [4%]: P = .022, relative risk 1.9, 95% confidence interval 1.1-3.2) was also greater after cesarean delivery than vaginal delivery. The incidence of persistent pain was significantly more common in women with a history of previous pain and among primiparous women in logistic regression analysis. The women with persistent pain had experienced more pain the day after cesarean delivery (P = .023) and during vaginal delivery (P = .030) than those who did not report persistent pain. Complications such as perineal trauma, episiotomy, vacuum extraction, endometritis, wound infection, or ante- or postpartum depression did not predispose women to persistent pain. Dyspareunia was reported by 41% of women after vaginal delivery and by 2% after cesarean delivery among women with persistent pain at 1 year. The incidence of persistent pain at 1 year is greater after cesarean delivery than after vaginal delivery. Pain shortly after cesarean delivery and during vaginal

Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures than neonatal birthweight. In the present study we aimed to evaluate the association of sonographically measured fetal head circumference measured within 1 week of delivery with delivery mode. This was a multicenter electronic medical record-based study of birth outcomes of primiparous women with term (37-42 weeks) singleton fetuses presenting for ultrasound with fetal biometry within 1 week of delivery. Fetal head circumference and estimated fetal weight were correlated with maternal background, obstetric, and neonatal outcome parameters. Elective cesarean deliveries were excluded. Multinomial regression analysis provided adjusted odds ratios for instrumental delivery and unplanned cesarean delivery when the fetal head circumference was ≥35 cm or estimated fetal weight ≥3900 g, while controlling for possible confounders. In all, 11,500 cases were collected; 906 elective cesarean deliveries were excluded. A fetal head circumference ≥35 cm increased the risk for unplanned cesarean delivery: 174 fetuses with fetal head circumference ≥35 cm (32%) were delivered by cesarean, vs 1712 (17%) when fetal head circumference cesarean delivery by an adjusted odds ratio of 1.75 (95% confidence interval, 1.4-2.18) controlling for gestational age, fetal gender, and epidural anesthesia. The rate of prolonged second stage of labor was significantly increased when either the fetal head circumference was ≥35 cm or the estimated fetal weight ≥3900 g, from 22.7% in the total

To examine whether labor compared with planned cesarean delivery is associated with increased maternal and neonatal morbidity. 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. A sample size of 338 women determined the study period and was selected to show a 30% difference in the incidence of the primary outcome between the two groups. Multivariate logistic regression adjusted for potential confounders. There were 344 women with BMIs of 50 or greater who met eligibility criteria, of whom 201 (58%) labored and 143 (42%) underwent planned cesarean delivery. Women who labored were younger, more likely to be nulliparous, and less likely to have pre-existing diabetes. Among women who labored, 45% underwent a cesarean delivery, most commonly for labor arrest (61%) or nonreassuring fetal status (28%). Composite maternal and neonatal morbidity was reduced among women who labored even after adjusting for age, parity, pre-existing diabetes, and prior cesarean delivery (adjusted odds ratio 0.42, 95% CI 0.24-0.75). In the subgroup of women (n=234) who underwent a cesarean delivery, whether planned (n=143) or after labor (n=91), there were no differences in maternal and neonatal morbidity except that severe maternal morbidity was increased in women (n=12) who labored (8.8% compared with 2.1%, relative risk 4.2, 95% CI 1.14-15.4). Despite high rates of cesarean delivery in women with superobesity, labor is associated with lower composite maternal and neonatal morbidity. Severe maternal morbidity may be higher in women who require a cesarean delivery after labor.

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. 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. This was a case-control study of women who had 2 consecutive singleton births of at least 36 weeks' gestation between 2005 and 2016, with a vaginal delivery in the index pregnancy. Women were excluded if they had a contraindication to a trial of labor (eg, fetal malpresentation or placenta previa) in the subsequent pregnancy. Maternal characteristics and delivery outcomes for both pregnancies were abstracted from the medical record. Maternal weight gain between deliveries was measured as the change in body mass index at delivery. Women who underwent a subsequent cesarean delivery were compared with those who had a repeat vaginal delivery using χ 2 statistics for categorical variables and Student t tests or analysis of variance for continuous variables. Multivariable logistic regression was used to determine whether interdelivery weight gain remained independently associated with intrapartum cesarean delivery after adjusting for potential confounders. Of 10,396 women who met eligibility criteria and had complete data, 218 (2.1%) had a cesarean delivery in the subsequent pregnancy. Interdelivery weight gain was significantly associated with cesarean delivery and remained significant in multivariable analysis for women with a body mass index increase of at least 2 kg/m 2 (adjusted odds ratio, 1.53, 95% confidence interval, 1.03-2.27 for a body mass index increase of 2 kg/m 2 to cesarean

Asthma was diagnosed prospectively by physicians at the research site, and associations with cesarean delivery were investigated using Cox proportional hazard models. From the Danish national prospective registry we included data from 1997......-2010. Childhood asthma was defined from recurrent use of inhaled corticosteroids filled at pharmacies. Cesarean delivery was classified as either before or after rupture of membranes, and the risk of asthma was compared with vaginal delivery. Results were adjusted stepwise for age and calendar year, sex, birth...

Background: Preterm birth is a major cause of neurodevelopmental disorders. Allopregnanolone, a key metabolite of progesterone, has neuroprotective and developmental effects in the brain. The objectives of this study were to measure the neuroactive steroid concentrations following preterm delivery in a neonatal guinea pig model and assess the potential for postnatal progesterone replacement therapy to affect neuroactive steroid brain and plasma concentrations in preterm neonates. Methods: Preterm (62-63 days) and term (69 days) guinea pig pups were delivered by cesarean section and tissue was collected at 24 hours. Plasma progesterone, cortisol, allopregnanolone, and brain allopregnanolone concentrations were measured by immunoassay. Brain 5α-reductase (5αR) expression was determined by Western blot. Neurodevelopmental maturity of preterm neonates was assessed by immunohistochemistry staining for myelination, glial cells, and neurons. Results: Brain allopregnanolone concentrations were significantly reduced after birth in both preterm and term neonates. Postnatal progesterone treatment in preterm neonates increased brain and plasma allopregnanolone concentrations. Preterm neonates had reduced myelination, low birth weight, and high mortality compared to term neonates. Brain 5αR expression was also significantly reduced in neonates compared to fetal expression. Conclusions: Delivery results in a loss of neuroactive steroid concentrations resulting in a premature reduction in brain allopregnanolone in preterm neonates. Postnatal progesterone therapy reestablished neuroactive steroid levels in preterm brains, a finding that has implications for postnatal growth following preterm birth that occurs at a time of neurodevelopmental immaturity.

Preterm delivery rates have remained consistently higher in the US than France, but the reasons for this excess remain poorly understood. We examined if differences in socio-demographic risk factors or more liberal use of obstetrical interventions contributed to higher rates in the US. Data on singleton live births in 1995, 1998 and 2003 from US birth certificates and the French National Perinatal Survey were used to analyze preterm delivery rate by maternal characteristics (age, parity, marital status, education, race (US)/nationality (France), prenatal care and smoking). We distinguished between preterm deliveries with a cesarean or a labor induction and those without these interventions. Unadjusted and adjusted risk ratios (RR) for the US compared to France were estimated using log-binomial regression. Preterm delivery rates were 7.9 % in the US and 4.7 % in France (risk ratio [RR] = 1.7, 95 % confidence interval [CI] 1.6-1.8). The US had more teen mothers and late entry to prenatal care, but fewer women smoked, although adjustment for these and other confounders did not reduce RR (1.8, 95 % CI 1.7-1.9). Preterm delivery rates associated with labor induction or cesarean were 3.3 % in the US and 2.1 % in France (RR 1.6, 95 % CI 1.5-1.7); the corresponding rates for preterm delivery without these interventions were 4.5 and 2.5 % (RR 1.8, 95 % CI 1.7-1.9), respectively. Key socio-demographic risk factors and more obstetric intervention do not explain higher US preterm delivery rates. Avenues for future research include the impact of universal access to health services (universal health insurance?) on health care quality and the association between more generous social policies, stress and the risks of preterm delivery.

To estimate the risks of cesarean first birth, compared with vaginal first birth, for adverse obstetric and perinatal outcomes in the second birth. Population-based retrospective cohort study of all singleton, second births in the South Australian perinatal data collection 1998 to 2003 comparing outcomes for 8,725 women who underwent a cesarean delivery for their first birth with 27,313 women who underwent a vaginal first birth. Predictor variables include age, indigenous status, smoking, pregnancy interval, medical and obstetric complications, gestation, patient type, hospital category, and history of ectopic pregnancy, miscarriage, stillbirth or termination of pregnancy. The cesarean delivery cohort had increased risks for malpresentation (odds ratio [OR] 1.84, 95% confidence interval [CI] 1.65-2.06), placenta previa (OR 1.66, 95% CI 1.30-2.11), antepartum hemorrhage (OR 1.23, 95% CI 1.08-1.41), placenta accreta (OR 18.79, 95% CI 2.28-864.6), prolonged labor (OR 5.89, 95% CI 3.91-8.89), emergency cesarean (relative risk 9.37, 95% CI 8.98-9.76) and uterine rupture (OR 84.42, 95% CI 14.64-infinity), preterm birth (OR 1.17, 95% CI 1.04-1.31), low birth weight (OR 1.30, 95% CI 1.14-1.48), small for gestational age (OR 1.12, 95% CI 1.02-1.23), stillbirth (OR 1.56, 95% CI 1.04-2.32), and unexplained stillbirth (OR 2.34, 95% CI 1.26-4.37). The range of the number of primary cesarean deliveries needed to harm included 134 for one additional preterm birth, up to 1,536 for one additional placenta accreta. Cesarean delivery is associated with increased risks for adverse obstetric and perinatal outcomes in the subsequent birth. However, some risks may be due to confounding factors related to the indication for the first cesarean. II.

The aim of this study was to examine the results of vaginal delivery in patients with a past history of cesarean section. The type of delivery, interventions during delivery, and the prognoses of the mothers and babies were examined in 145 women with a history of cesarean section over the 10-year period from January 2000 to December 2009. A scheduled cesarean section was performed in 27 cases. Vaginal delivery was recommended in 118 cases and the success rate was 94.9% (112/118). Uterine rupture was observed in one patient who experienced a natural rupture at home and whose previous cesarean section was an inverse T incision. No cases required a blood transfusion or hysterectomy. The prognoses of both mothers and babies were good and the vaginal delivery success rate was 94.9%. Uterine rupture was observed in one case. Vaginal delivery with previous cesarean section should be considered in cases with expectation and informed consent. © 2011 The Authors.

The purpose of this study was to examine the association between previous cesarean delivery and subsequent placenta previa while distinguishing cesarean delivery before the onset of labor from intrapartum cesarean delivery. We conducted a retrospective cohort study of electronic medical records from 20 Utah hospitals (2002-2010) with restriction to the first 2 singleton deliveries of nulliparous women at study entry (n=26,987). First pregnancy delivery mode was classified as (1) vaginal (reference), (2) cesarean delivery before labor onset (prelabor), or (3) cesarean delivery after labor onset (intrapartum). Risk of second delivery previa was estimated by previous delivery mode with the use of logistic regression and was adjusted for maternal age, insurance, smoking, comorbidities, previous pregnancy loss, and history of previa. Most first deliveries were vaginal (82%; n=22,142), followed by intrapartum cesarean delivery (14.6%; n=3931), or prelabor cesarean delivery (3.4%; n=914). Incidence of second delivery previa was 0.29% (n=78) and differed by previous delivery mode: vaginal, 0.24%; prelabor cesarean delivery, 0.98%; intrapartum cesarean delivery, 0.38% (Pdelivery, previous prelabor cesarean delivery was associated with an increased risk of second delivery previa (adjusted odds ratio, 2.62; 95% confidence interval, 1.24-5.56). There was no significant association between previous intrapartum cesarean delivery and previa (adjusted odds ratio, 1.22; 95% confidence interval, 0.68-2.19). Previous prelabor cesarean delivery was associated with a >2-fold significantly increased risk of previa in the second delivery, although the approximately 20% increased risk of previa that was associated with previous intrapartum cesarean delivery was not significant. Although rare, the increased risk of placenta previa after previous prelabor cesarean delivery may be important when considering nonmedically indicated prelabor cesarean delivery.

Study Design Retrospective cohort study of electronic medical records from 20 Utah hospitals (2002–2010) with restriction to the first two singleton deliveries of women nulliparous at study entry (n=26,987). First pregnancy delivery mode was classified as 1) vaginal (reference); 2) cesarean delivery prior to labor onset (prelabor); or 3) cesarean delivery after labor onset (intrapartum). Risk of second delivery previa was estimated by prior delivery mode using logistic regression and adjusted for maternal age, insurance, smoking, co-morbidities, prior pregnancy loss, and history of previa. Results The majority of first deliveries were vaginal (82%, n=22,142), followed by intrapartum cesarean delivery (14.6%, n=3,931), or prelabor cesarean delivery (3.4%, n=914). Incidence of second delivery previa was 0.29% (n=78) and differed by prior delivery mode: vaginal, 0.24%; prelabor cesarean delivery, 0.98%; intrapartum cesarean delivery, 0.38% (Pdelivery, prior prelabor cesarean delivery was associated with an increased risk of second delivery previa (adjusted odds ratio, 2.62 [95% confidence interval, 1.24–5.56]). There was no significant association between prior intrapartum cesarean delivery and previa [adjusted odds ratio, 1.22 (95% confidence interval, 0.68–2.19)]. Conclusion Prior prelabor cesarean delivery was associated with a more than two-fold significantly increased risk of previa in the second delivery, while the approximately 20% increased risk of previa associated with prior intrapartum cesarean delivery was not significant. Although rare, the increased risk of placenta previa after prior prelabor cesarean delivery may be important when considering non-medically indicated prelabor cesarean delivery. PMID:25576818

Background What role should previous cesarean section play in affecting clinical pregnancy outcomes and avoiding the complications of in vitro fertilization? In this article, we focus on elective single-embryo transfer (eSET) versus double-embryo transfer (DET) and assess the clinical efficacy and safety of eSET in patients who have a previous cesarean scar. Material/Methods The pregnancy, delivery, and neonatal outcomes of 130 patients who had a previous cesarean scar and received in vitro fertilization-embryo transfer (IVF-ET) were retrospectively analyzed. The number of transferred embryos was chosen depending on patients’ desire after acknowledging all benefits and risks, including eSET (eSET group, n=56) and DET (DET group, n=74). A total of 101 patients with previous vaginal delivery receiving IVF-ET in the same period were included as a control group. Results The pregnancy rates, multiple birth rates, abortion rates, ectopic pregnancy rates, gestational age at delivery, preterm birth rates, neonatal birth weight, and take-home baby rates were similar between the previous cesarean section group and the previous vaginal delivery group. A previous cesarean section scar did not affect embryo implantation and pregnancy outcomes in IVF. In the eSET and DET groups of previous cesarean section patients, the embryo implantation rates, pregnancy rates, abortion rates, and take-home baby rates were similar. However, the rate of multiple pregnancies reached 50% in the DET group, which led to more preterm births and lower birth weight. Conclusions Elective single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies and improve the obstetric and neonatal outcomes of singleton pregnancy in IVF patients with a previous cesarean section.

To investigate the relationship between preterm delivery and anterior myometrial (MA) thickness measured by ultrasound in the second trimester. The general information and pregnancy outcome of singleton pregnant women who had antenatal visit in the Hunan Provincial People's Hospital between Oct 2010 and Sep 2013 were collected prospectively. The MA thickness was measured at 20-27(+6) gestational weeks. The cases were divided into preterm delivery group and term delivery group. (1) A total of 1 031 pregnant women were recruited in this study. 147 pregnant women were in the preterm delivery group (14.26%, 147/1 031) and 884 women were in the term delivery group (85.74% , 884/1 031). The gestation age at delivery of the preterm delivery group was significantly earlier than the term delivery group [(34.57 ± 2.39) vs (39.23 ± 0.92) weeks, P history of preterm delivery, cesarean delivery rate and gestational age at the time of MA measurement between the two groups (P > 0.05). The incidence of premature rupture of membrane (PROM) in the preterm delivery group and in the term delivery group were 49.0% (72/147) and 15.8% (140/884), respectively, with statistically significant difference (P delivery group was (5.49 ± 1.39) mm, while in the preterm delivery group it was (5.60 ± 0.87) mm. There was no statistically significant difference between the two groups(P > 0.05).

The objective of this study was to test whether hospitals experienced in twin delivery have lower rates of cesarean delivery for twins. We divided obstetric hospitals in the 2011 National Inpatient Sample by quartile of annual twin deliveries and compared twin cesarean delivery rates between hospitals with weighted linear regression. We used Pearson's coefficients to correlate a hospital's twin cesarean delivery rate to its overall cesarean delivery and vaginal birth after cesarean (VBAC) rates. Annual twin delivery volume ranged from 1 to 506 across the 547 analyzed hospitals with a median of 10 and mode of 3. Adjusted rates of cesarean delivery were independent of delivery volume with a rate of 75.5 versus 74.8% in the lowest and highest volume hospitals ( p = 0.09 across quartiles). A hospital's cesarean delivery rate for twins moderately correlated with the overall cesarean rate ( r = 0.52, p cesarean delivery rates at higher volume hospitals. Twin cesarean delivery rates correlate with other obstetric parameters such as singleton cesarean delivery and VBAC rates suggesting twin cesarean delivery rate is more closely related to a hospital's general obstetric practice than its twin delivery volume.

Cesarean delivery rates are rising due to multiple factors, including less use of operative vaginal delivery and vaginal birth after cesarean delivery, which often reflect local obstetric practices. Objectives of the study were to analyze the relations between cesarean delivery, these practices, and perinatal outcomes. We included all deliveries in the 72 hospitals of Lombardia, a region in northern Italy, during the year 2013. The delivery certificate was used as data source. Pearson's correlation coefficient and logistic regression were used for statistical analysis. We included 87 896 deliveries. The number of deliveries per hospital ranged from 140 to 6123. The rate of cesarean delivery was 28.3% (range 9.9-86.4%), operative vaginal delivery 4.7% (range 0.2-10.0%), and vaginal birth after cesarean 17.3% (range 0-79.2%). We found a significant inverse correlation between rates of overall cesarean delivery and operative vaginal delivery (r = -0.25, p = 0.04). The correlation between rate of overall cesarean delivery and vaginal birth after cesarean was also inverse and significant (r = -0.57, p cesarean delivery rate and the rates of Apgar score at 5 min cesarean delivery, could reduce the rising cesarean delivery rate. This will require a change in obstetric culture, continuing education of healthcare providers, and leadership. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Hematometra resulting from partial or complete obstruction of lower genital tract may be congenital or acquired. Commonest congenital causes are imperforate hymen and transverse vaginal septum. Acquired causes are senile atrophy of endocervical canal, scarring of the isthmus by synechiae, radiation and endocervical malignancy or due to surgical procedures. Various surgical procedures associated with hematometra are dilatation and curettage, cone biopsy, endometrial ablation, cryocoagulation and electrocautery. Hematometra following an abortion or cesarean delivery is rare. We report a case of hematometra following obstruction of outflow tract due to prior cesarean delivery.

The study is a critical analysis of the decisions to induce labour or schedule cesareans in the practice of a third level referral centre, with as outcome criterion the reduction of fetal death. 783 women pregnant with twins were included from 1.1.1993 to 31.12.1998, in three groups: originally booked, referred for care during pregnancy, or transferred from another institution. The results show that an important proportion of preterm deliveries result from a medical decision to induce labour or from a scheduled cesarean in the originally booked group with even higher proportions in groups of referred and transferred women. These results are discussed in relation to fetal death rates and causes. Deaths related to fetal growth restriction were not observed in women originally booked for care. The hospital bias has been discussed. The conclusion is that decisions to minimize fetal deaths in twin pregnancies increased preterm deliveries by medical decision.
Objective: The aim of the present study was to evaluate the optimum dose of ropivacaine by comparing three different dosing regimens of isobaric ropivacaine 1% (naropin 10 mg/ml, Astra Zeneca) administered intrathecally and to demonstrate the effects of anesthesia in pregnant women scheduled for cesarean section.

Objective: To identify the risk factors for cesarean delivery among primigravida at Hospital Serdang. Methodology: This was a case control study which involved total 260 of 130 primigravida patients that underwent cesarean section (cases) and 130 primigravida patients that underwent vaginal delivery (control) at obstetrics and gynaecology department of Hospital Serdang, Malaysia from January until June 2013. A standardized proforma was used to collect the data of each primigravida patient presenting in spontaneous labour at term with singleton pregnancy with either caesarean or vaginal delivery. Results: Majority of the cases were Malaysian (86.9%) and mostly were from Malay ethnic group (75.4%). In multivariate logistic regression analysis, presence of hypertension status (odds ratio (OR) 5.7, 95% CI; 1.56-20.84) and gestational age less than 40 weeks (OR 2.60, 95% CI 1.34-5.02), fetal weight more than 3000 gm (OR 1.8, 95% CI 1.1-2.95), were associated with higher odds of cesarean delivery. Conclusion: Primigravida with presence of hypertension, having gestational age less than 40 weeks and heavier fetus were associated with higher odds of cesarean delivery. (author)

Full Text Available Background/Aim. The optimal method of delivery for breech presentation at term still remains a matter of controversy. This is probably due to the fact that the skills of vaginal breech delivery are being lost. The aim of this study was to examine risk factors: mother's age, parity, labor's duration, estimated neonatal birth weight for the mode of breech presentation delivery at term as well as the influence of the delivery mode on neonatal outcome. Methods. A retrospective study of 401 terms (more than 37 week's gestation breech deliveries at the Institute of Gynecology and Obstetrics, Belgrade, from 2007 to 2008 was made. The following groups with respect to mode of delivery were included: the group I - vaginal delivery (VD in 139 patients; the group II - urgent cesarean section (UCS in 128 patients; and the group III - elective cesarean section (ECS in 134 patients. Mother's age, parity, duration of VD, neonatal birth weight (BW, the Apgar score at 5th minute, and duration of stay in a neonatal intensive care unit (NICU vere determined. Neonatal mortality and major neonatal morbidity were compared according to the route of delivery. Fetuses and neonates with hemolytic disease and fetal and neonatal anomalies were excluded from the study. For statistical analyses we performed Student's t test, χ2 likelihood ratio, Kruskall-Wallis test, Mann Whitney test, and ANOVA. Results. The mean age of patients in the group I was 28.29 ± 4.97 years, in the group II 29.68 ± 5.92 years and in the group III 30.06 ± 5.41 years. Difference in mother's age between the group I and III was significant (p = 0.022. In the group III there were 73.9% nuliparous similarly to the gropu II (73.4%. We performed ECS in 54.6% of the nuliparous older than 35 years, and 54.4% multiparous younger than 35 years were delivered by VD. The use of oxytocin for stimulation of vaginal labor was not associated with its duration (p = 0.706. Lowset maneuver was performed in 88.5% of

Conclusion: In women who have had prior vaginal birth attempting a trial of labor after cesarean, a vaginal delivery before cesarean delivery is an independent risk factor for repeat cesarean. Women with two or more prior vaginal births have a similar risk for repeat cesarean and neonatal admission to women with only one prior vaginal birth.

Multiple studies have demonstrated an association between maternal obesity and postoperative complications, but there is a dearth of information about the impact of obesity on intraoperative complications. To estimate the association between maternal obesity at delivery and major intraoperative complications during cesarean delivery (CD). This is a secondary analysis of the deidentified Maternal-Fetal Medicine Unit Cesarean Registry of women with singleton pregnancies. Maternal body mass index (BMI) at delivery was categorized as BMI 18.5 to 29.9 kg/m 2 , BMI 30 to 39.9 kg/m 2 , BMI 40 to 49.9 kg/m 2 , and BMI ≥ 50 kg/m 2 . The primary outcome, any intraoperative complication, was defined as having at least 1 major intraoperative complication, including perioperative blood transfusion, intraoperative injury (bowel, bladder, ureteral injury; broad ligament hematoma), atony requiring surgical intervention, repeat laparotomy, and hysterectomy. Log-binomial models were used to estimate risk ratios of intraoperative complication in 2 models: model 1 adjusting for maternal race, and preterm delivery <37 weeks; and model 2 adjusting for confounders in Model 1 as well as emergency CD, and type of skin incision. A total of 51,218 women underwent CD; 38% had BMI 18.5 to 29.9 kg/m 2 , 47% BMI 30 to 39.9 kg/m 2 , 12% BMI 40 to 49.9 kg/m 2 and 3% BMI ≥ 50 kg/m 2 . Having at least 1 intraoperative complication was uncommon (3.4%): 3.8% for BMI 18.5 to 29.9 kg/m 2 , 3.2% BMI 30 to 39.9 kg/m 2 , 2.6% BMI 40 to 49.9 kg/m 2 and 4.3% BMI ≥ 50 kg/m 2 (P < .001). In the fully adjusted model 2, women with BMI 40 to 49.9 kg/m 2 had a lower risk of any intraoperative complication (adjusted risk ratio [ARR], 0.76; 95% confidence interval [CI], 0.64 to 0.89) compared with women with BMI 18.5 to 29.9 kg/m 2 . Women with BMI 30 to 39.9 kg/m 2 (ARR, 0.93; 95% CI, 0.84 to 1.03) had a similar risk of any intraoperative complication compared with nonobese women. Among super obese women
Full Text Available Abstract Background To determine whether patients with placenta previa who delivered preterm have an increased risk for recurrent spontaneous preterm birth. Methods This retrospective population based cohort study included patients who delivered after a primary cesarean section (n = 9983. The rate of placenta previa, its recurrence, and the risk for recurrent preterm birth were determined. Results Patients who had a placenta previa at the primary CS pregnancy had an increased risk for its recurrence [crude OR of 2.65 (95% CI 1.3-5.5]. The rate of preterm birth in patients with placenta previa in the primary CS pregnancy was 55.9%; and these patients had a higher rate of recurrent preterm delivery than the rest of the study population (p Conclusions Women with placenta previa, who deliver preterm, especially before 34 weeks of gestation, are at increased risk for recurrent spontaneous preterm birth regardless to the site of placental implantation in the subsequent pregnancy. Thus, strict follow up by high risk pregnancies specialist is recommended.

Postpartum uterine contraction pain is a common phenomenon after Cesarean delivery. We investigated the effectiveness of tenoxicam in reducing uterine contraction pain. We enrolled 120 consecutive non-breastfeeding women who were scheduled for elective Cesarean delivery. After the administration of spinal anesthesia with bupivacaine and intrathecal morphine 0.15 mg injection, the patients were randomly divided into two groups. Group I received placebo (normal saline) iv injection, and Group II received tenoxicam 40 mg iv injection after clamping the umbilical cord. Verbal analogue scale of wound pain and uterine contraction pain were recorded at two, four, eight,16, and 24 hr after Cesarean delivery. There was no significant difference in wound pain scores between the two groups (all scores pain scores and required less supplemental meperidine medication than did the placebo group (8.5% vs 41.4%, P <0.05). The incidences of nausea or vomiting, pruritus, and bleeding were not significantly different between groups. Intravenous tenoxicam 40 mg significantly reduced the intensity of uterine cramps in patients undergoing Cesarean delivery without increasing side effects.

Shivering associated with spinal anesthesia during Cesarean delivery is an uncomfortable experience for the parturient, which may also cause adverse effects. In this prospective, randomized, double-blind, placebo-controlled study, we sought to evaluate the effect of intrathecal dexmedetomidine, administered as an adjunct to hyperbaric bupivacaine for Cesarean delivery, on the incidence and severity of shivering associated with spinal anesthesia. Patients undergoing Cesarean delivery were randomly allocated to three groups of 30 patients each. Experimental treatments were added to hyperbaric bupivacaine as follows: Patients in group I (control) were administered isotonic saline. Patients in groups II and III received dexmedetomidine (2.5, 5 µg, respectively), mixed with isotonic saline. Shivering was observed in 11, 10 and 2 patients in groups I, II and III, respectively. The incidence of shivering in group III was significantly lower than that in groups I (p=0.005) and II (p=0.01). The severity of shivering was significantly different between the three groups (p=0.01). There were no significant inter-group differences with respect to mean arterial pressure and heart rate at any time point after administration of intrathecal local anesthesia (p>0.05). Intrathecal dexmedetomidine (5 µg) administered as an adjunct to hyperbaric bupivacaine during Cesarean delivery significantly reduced the incidence and intensity of shivering associated with spinal anesthesia.

Background Obesity is a known risk factor for cesarean delivery. Limited data are available regarding the reasons for the increased rate of primary cesarean in obese women. It is important to identify the factors leading to an increased risk of cesarean to identify opportunities to reduce the primary cesarean rate. Objective We evaluated indications for primary cesarean across body mass index kg/m2 classes to identify the factors contributing to the increase rate of cesarean among obese women. Study design In the Consortium of Safe Labor study between 2002 and 2008, we calculated indications for primary cesarean including failure to progress or cephalopelvic disproportion, non-reassuring fetal heart tracing, malpresentation, elective, hypertensive disease, multiple gestation, placenta previa or vasa previa, failed induction, human immunodeficiency virus or active herpes simplex virus, history of uterine scar, fetal indication, placental abruption, chorioamnionitis, macrosomia, and failed operative delivery. For women with primary cesarean for failure to progress or cephalopelvic disproportion, dilation at the last recorded cervical examination was evaluated. Women were categorized according to body mass index on admission: normal weight (18.5-24.9), overweight (25.0-29.9), obese class I (30.0-34.9), II (35.0-39.9), and III (≥40). Cochran-Armitage Trend Test and Chi-square tests were performed. Results Of 66,502 nulliparous and 76,961 multiparous women in the study population, 19,431 nulliparous (29.2%) and 7,329 multiparous women (9.5%) underwent primary cesarean. Regardless of parity, malpresentation, failure to progress or cephalopelvic disproportion, and non-reassuring fetal heart tracing were the common indications for primary cesarean. Regardless of parity, the rates of primary cesarean for failure to progress or cephalopelvic disproportion increased with increasing body mass index (normal weight, class I, II and III obesity in nulliparous: 33.2%, 41.6%, 46

Preoperative skin antisepsis has the potential to decrease the risk of surgical-site infection. However, evidence is limited to guide the choice of antiseptic agent at cesarean delivery, which is the most common major surgical procedure among women in the United States. In this single-center, randomized, controlled trial, we evaluated whether the use of chlorhexidine-alcohol for preoperative skin antisepsis was superior to the use of iodine-alcohol for the prevention of surgical-site infection after cesarean delivery. We randomly assigned patients undergoing cesarean delivery to skin preparation with either chlorhexidine-alcohol or iodine-alcohol. The primary outcome was superficial or deep surgical-site infection within 30 days after cesarean delivery, on the basis of definitions from the Centers for Disease Control and Prevention. From September 2011 through June 2015, a total of 1147 patients were enrolled; 572 patients were assigned to chlorhexidine-alcohol and 575 to iodine-alcohol. In an intention-to-treat analysis, surgical-site infection was diagnosed in 23 patients (4.0%) in the chlorhexidine-alcohol group and in 42 (7.3%) in the iodine-alcohol group (relative risk, 0.55; 95% confidence interval, 0.34 to 0.90; P=0.02). The rate of superficial surgical-site infection was 3.0% in the chlorhexidine-alcohol group and 4.9% in the iodine-alcohol group (P=0.10); the rate of deep infection was 1.0% and 2.4%, respectively (P=0.07). The frequency of adverse skin reactions was similar in the two groups. The use of chlorhexidine-alcohol for preoperative skin antisepsis resulted in a significantly lower risk of surgical-site infection after cesarean delivery than did the use of iodine-alcohol.

Background: Data was reported in Iran in 2013 has shown that almost 42 percent of deliveries in public hospitals and 90 percent in private hospitals were carried out with cesarean section. This high rate of cesarean requires careful consideration. It seems that making decision for cesarean is done under the influence of cultural perceptions and beliefs. So, this study was conducted to explore pregnant women's preferences and perceptions regarding cesarean delivery. Materials and Methods: A focused ethnographic study was used. 12 pregnant women and 10 delivered women, seven midwives, seven gynecologist and nine non-pregnant women referred to the health clinics of Tonekabon, who selected purposively, were included in the study. To collect data semi-structured in-depth interviews and participant observation were used. Study rigor was confirmed through prolonged engagement, member check, expert debriefing, and thick description of the data. Data were analysed using thematic analysis and MAXQDA software. Results: Four themes emerged from the data including personal beliefs, fear of vaginal delivery, cultural norms and values and also social network. These concepts played main roles in how women develop meanings toward caesarean, which affected their perceptions and preferences in relation to caesarean delivery. Conclusion: Most of pregnant women believed that fear of vaginal delivery is a major factor to choose caesarean delivery. Hence, midwives and physicians could help them through improving the quality of prenatal care and giving them positive perception towards vaginal delivery through presenting useful information about the nature of different modes of delivery, and their advantages and disadvantages, as well as the alternative ways to control labor pain.

The prevailing obstetric practice of planned cesarean delivery for triplet gestations is largely empiric and data on the optimal route of delivery are limited. The primary objectives of this study are to determine the likelihood of success in an attempted vaginal delivery and assess maternal and neonatal outcomes of attempted vaginal vs planned cesarean delivery of triplets using a multiinstitution obstetric cohort. We performed a retrospective cohort study using data from the Consortium on Safe Labor, identifying triplet pregnancies with delivery at a gestational age ≥28 weeks. Women with a history of cesarean delivery and pregnancies complicated by chromosomal or congenital anomalies, twin-twin transfusion syndrome, or a fetal demise were excluded. The attempted vaginal group included all women with spontaneous or induced labor and excluded all women delivering by prelabor cesarean delivery, including those coded as elective or for fetal malpresentation. Primary maternal outcomes included infection (composite of chorioamnionitis, endometritis, wound separation, and wound infection), blood transfusion, or transfer to the intensive care unit. Primary neonatal outcomes included neonatal asphyxia, mechanical ventilation, and composite neonatal morbidity, consisting of ≥1 of the following: birth injury, 5-minute Apgar delivery group was restricted to include only women with evidence of induction or augmentation or labor. 188 triplet sets were identified of which 80 sets (240 neonates) met inclusion criteria and 24 sets (30%) had an attempted vaginal delivery. The rate of successful attempted vaginal delivery was 16.7% (4 triplet sets; 12 neonates). No women had a combined mode of delivery. Women attempting vaginal delivery were more likely to have preterm labor (45.8 vs 12.5%, P delivery did not differ by mode of delivery. Attempted vaginal delivery was associated with a higher risk of maternal transfusion (20.8% vs 3.6%, P = .01) and neonatal mechanical

To identify trends and risk factors for early surgical site infection (SSI) following cesarean delivery (CD). A population-based study comparing characteristics of women who have and have not developed post cesarean SSI was conducted. Deliveries occurred between the years 1988 and 2013 in a tertiary medical center. A multivariable logistic regression model, with backwards elimination, was used to control for confounders. Of the 41 375 cesarean deliveries performed during the study period, 1521 (3.7%) were complicated with SSI. SSI rates significantly deceased over the years, from 7.4% in 1988 to 1.5% in 2012. Using a multivariable regression model, the following independent risk factors for SSI were identified: obesity (OR 2.0; 95% CI, 1.6-2.5); previous CD (OR 1.8; 95% CI, 1.6-2.0); hypertensive disorders (OR 1.4; 95% CI, 1.2-1.6); premature rupture of membranes (OR 1.3; 95% CI, 1.1-1.6); gestational diabetes mellitus (GDM, OR 1.2; 95% CI, 1.1-1.4); and recurrent pregnancy losses (OR 1.2; 95% CI, 1.1-1.5). Independent risk factors for post-cesarean SSI include obesity, GDM, hypertensive disorders of pregnancy, premature rupture of membranes, and recurrent pregnancy losses. Information regarding higher rates of SSI and preventative measures should be provided to these high-risk women prior to surgery.

To identify independent risk factors for Cesarean delivery in women with pregnancy complicated by diabetes. Retrospective analysis of pregnancies from 5735 diabetic women delivering liveborn infants. Maternal demographic, medical, obstetric historical factors and index pregnancy obstetric, glycemic and neonatal outcome parameters were evaluated for association with Cesarean delivery after a trial of labor. Individual risk factors were analyzed for association by chi2 and ANOVA. Independent predictors of Cesarean delivery and adjusted relative risk (RR) were identified by stepwise logistic regression. Trial of labor was permitted in 90.8% and 59.4% of women without (n = 4643) and with prior Cesarean delivery (n = 1092) and was successful in 85.2% and 56.9%, respectively. Eleven independent predictors were found. Five were related to obstetric history and maternal age: prior Cesarean delivery (RR 5.34, 95% CI 3.94-7.25), no prior live birth (RR 3.17, 95% CI 1.98-5.07), no prior vaginal delivery (RR 2.28, 95% CI 1.50-3.44), prior stillbirth (RR 1.71, 95% CI 1.09-2.68%) and maternal age > or = 35 years (RR 1.53, 95% CI 1.20-1.93). Two were related to the severity of diabetes at entry to diabetes care: requiring insulin (RR 1.53, 95% CI 1.20-1.93) and highest fasting plasma glucose level (RR 1.04, 95% CI 1.01-1.07). Two were related to obstetric factors: pre-eclampsia/hypertension (RR 2.56, 95% CI 2.00-3.27) and labor induction (RR 3.32, 95% CI 2.70-4.10). The remaining two were birth weight (per 250 g, RR 1.12, 95% CI 1.09-1.17) and pre-delivery body mass index (RR, 1.03, 95% CI 1.00-1.05). The majority of predictors were not modifiable, relating to obstetric history, maternal age and diabetes severity. Possible modifiable interventions to avoid/improve labor induction, and decrease birth weight and maternal weight gain might decrease risk of Cesarean delivery. Future studies must address these multiple predictors.

Studies examining the effects of various analgesics and anesthetics on postoperative pain following cesarean delivery conventionally use the scheduled cesarean population. This study compares postoperative analgesic requirements and recovery profiles in women undergoing scheduled cesarean compared to unplanned cesarean delivery following labor. We postulated that unplanned cesarean deliveries may increase postoperative analgesic requirements. We conducted a retrospective chart review of 200 cesarean deliveries at Lucile Packard Children's Hospital, California. We examined the records of 100 patients who underwent scheduled cesarean delivery under spinal anesthesia (hyperbaric bupivacaine 12 mg with intrathecal fentanyl 10 microg and morphine 200 microg) and 100 patients that following a trail of labor required unplanned cesarean under epidural anesthesia (10-25 mL 2% lidocaine top-up with epidural morphine 4 mg after clamping of the umbilical cord). We recorded pain scores, analgesic consumption, time to first analgesic request, side effects, and length of hospital stay. We found no differences in postoperative pain scores and analgesic consumption between scheduled and unplanned cesarean deliveries for up to five days postoperatively. There were no differences in treatment of side effects such as nausea, vomiting, or pruritus (P>0.05). The results indicate that women experience similar pain and analgesic requirements after scheduled compared to unplanned cesarean delivery. This suggests that the non-scheduled cesarean population may be a suitable pain model to study pain management strategies; and that alterations in pain management are not necessary for the unplanned cesarean delivery population.

To assess the rate of cesarean delivery and its indications at public emergency obstetric care (EmOC) hospitals in a district in Bangladesh. In a retrospective, cross-sectional study, data were extracted from the Safe Motherhood Promotion Project database and operation theater registers for cesarean deliveries at three district and three subdistrict EmOC hospitals in Narsingdi between January 1 and December 31, 2008. Information on cesarean deliveries and their indications, and maternal and neonatal outcomes were analyzed descriptively. Among 3329 deliveries, 1075 (32.3%) occurred by cesarean. The frequency of cesarean delivery ranged from 17.8% (147 of 824 deliveries) to 56.3% (174 of 309) among the six hospitals. Information on indications was available for 1043 cesarean deliveries. The main indications were previous cesarean delivery (251 deliveries, 24.1%), fetal distress (228, 21.9%), and prolonged or obstructed labor (214, 20.5%). There were no maternal deaths, but 10 (1.0%) cesarean deliveries resulted in stillbirth. The overall rate of cesarean delivery was high at EmOC hospitals. Interventions to improve decision making and limit possible unnecessary cesarean operations are needed. Copyright © 2014 International Federation of Gynecology and Obstetrics.

Full Text Available OBJECTIVE: To estimate the incidence of incisional hernias requiring surgical repair after cesarean delivery over a 10-year period. METHODS: This population- and register-based cohort study identified all women in Denmark with no history of previous abdominal surgery who had a cesarean delivery between 1991 and 2000. The cohort was followed from their first until 10 years after their last cesarean delivery within the inclusion period or until the first of the following events: hernia repair, death, emigration, abdominal surgery, or cesarean delivery after the inclusion period. For women who had a hernia repair, hospital records regarding the surgery and previous cesarean deliveries were tracked and manually analyzed to validate the relationship between hernia repair and cesarean delivery. Data were analyzed with a competing risk analysis that included each cesarean delivery. RESULTS: We identified 57,564 women who had had 68,271 cesarean deliveries during the inclusion period. During follow-up, 134 of these women had a hernia requiring repair. Of these 68 (51% [95% CI 42-60%] were in a midline incision although the transverse incision was the primary approach at cesarean delivery during the inclusion period. The cumulated incidence of a hernia repair within 10 years after a cesarean delivery was 0.197% (95% CI 0.164-0.234%. The risk of a hernia repair was higher during the first 3 years after a cesarean delivery, with an incidence after 3 years of 0.157% (95% CI 0.127-0.187%. CONCLUSIONS: The overall risk of an incisional hernia requiring surgical repair within 10 years after a cesarean delivery was 2 per 1000 deliveries in a population in which the transverse incision was the primary approach at cesarean delivery.
Full Text Available OBJECTIVE: To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. STUDY DESIGN: Women delivered of a singleton birth (n = 8228, recruited from five public level III maternities (April 2005-August 2006 during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908, non-Portuguese European (n = 84, African (n = 77 and Brazilian (n = 159. A Poisson model was used to evaluate the association between country of birth and cesarean section that was measured by adjusted prevalence ratio (PR and respective 95% confidence intervals (95%CI. RESULTS: The cesarean section rate varied from 32.1% in non-Portuguese European to 48.4% in Brazilian women (p = 0.008. After adjustment for potential confounders and compared to Portuguese women as a reference, Brazilian women presented significantly higher prevalence of cesarean section (PR = 1.26; 95%CI: 1.08-1.47. The effect was more evident among multiparous women (PR = 1.39; 95%CI: 1.12-1.73 and it was observed when cesarean section was performed either before labor (PR = 1.43; 95%CI: 0.99-2.06 or during labor (PR = 1.30; 95%CI: 1.07-1.58. CONCLUSIONS: The rate of cesarean section was significantly higher among Brazilian women and it was independent of the presence of any known risk factors or usual clinical indications, suggesting that cultural background influences the mode of delivery overcoming the expected standard of care and outcomes in public health services.

Preterm delivery is associated with high mortality and morbility perinatal, being the costs dispended by the family and the National Health System with preterm newborns extremely high. However, it has been difficult to reduce its incidence due to the various factors involved. There is scientific evidence which support the relationship between periodontal disease and preterm delivery. There is also evidence of tobacco as a risk factor for periodontal disease, even though the relationship with preterm delivery is not yet clear. The aims of our study were to evaluate, in women in a post-partum period, dental and periodontal status as well as the exposure to tobacco and to establish the relationship between these two factors with preterm delivery. We performed a case control study with 237 parturient women from the Department of Obstetrics and Gynecology of Hospital S. João, E.P.E., during the first 48 hours after birth. A total of 86 gave birth at a gestational age under 37 weeks (case group ) and 151 gave birth to term newborns with birthweight equal or superior 2500 g (control group). The prevalence of some indicators of periodontal disease in the studied population was extremely high, namely gingival inflammation and gingival recession, and more of 30% had values of probing depth equal or higher than 4 mm significantly. Based on these periodontal indicators, only the presence of recession in more than two teeth seems to increase the risk of preterm delivery in fivefold (OR = 5,28; IC95%: 1,63-17,04). There is a statistically significant association between probing depth equal or higher than 4mm and smoking during pregnancy. This association might be relevant because 20% of preterm newborns mothers smoked during pregnancy and the proportion that stopped smoking during pregnancy in this group of mothers was almost half of the number of the control group. Therefore it is necessary to embody the information about this thematic in the health education, not only in

Full Text Available Introduction - Fat embolism is a rare form of nonthrombotic embolization. Limited literature exists regarding the diagnosis of fat embolism during the perinatal period. We present the first case of maternal death that resulted from nontraumatic fat embolization following Cesarean delivery. Case Description - A 29-year-old gravida 1 with a complex medical and surgical history underwent a primary Cesarean delivery at term. On postoperative day 2 the patient was found to be unresponsive. Despite resuscitative efforts, the patient succumbed. Autopsy findings were remarkable for diffuse pulmonary fat emboli. Furthermore, there was no histological evidence of either amniotic fluid embolism or thromboembolism. The primary cause of death was attributed to nontraumatic fat embolization. Discussion - Multiple risk factors may have contributed to the development of nontraumatic fat embolization in our patient. Obstetricians should maintain a high level of suspicion for nontraumatic fat embolization in cases of maternal respiratory decompression and sudden maternal mortality.

Physicians are often alleged responsible for the manipulation of delivery timing. We investigate this issue in a setting that negates the influence of financial incentives on physician's behavior. Working on a sample of women admitted at the onset of labor in a big public hospital in Italy we estimate a model for the exact time of delivery as driven by individual Indication to Cesarean Section (ICS) and covariates. We find that ICS does not affect the day of delivery but leads to a circadian rhythm in the likelihood of delivery. The pattern is consistent with the postponement of high ICS deliveries in the late night\\early morning shift. Our evidence hardly supports the manipulation of timing of births as driven by medical staff's "demand for leisure". Physicians seem to manipulate the exact timing of delivery to reduce exposure to risk factors extant during off-peak periods. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

In present clinical practice there is an increasing number of patients with delivery with previous cesarean section which is frequent reason for the repeated one. The most serious complication in labour with previous cesarean section is the rupture of the uterus which is as frequent in labour by natural way as in repeated cesarean section. This is a reason that many of obstetricians do not support attitude "Once cesarean section, always a cesarean". In a retrospective study in five years period beginning January 1, 1998, we analyzed total number of deliveries, total number of cesarean section, way of deliveries with previous cesarean section and frequency of complications. We used Chi2 test and Contigency table. In analyzed period from January 1, 1998 through December 31, 2002, we completed 24,194 deliveries at Ob/Gyn Clinic in Tuzla. Out of this number we performed 4073 cesarean sections or 16.83%. Out of 24,194 deliveries we had 1328 (5.49% of all deliveries) deliveries after performed cesarean in previous pregnancy. Out of 1328 deliveries following cesarean we completed by natural way 323 pregnancies or 24.33% and by repeated cesarean 1005 or 75.67%. Previous one cesarean had 1191, previous two cesarean 126, and previous three cesarean had 11 women. Out of 1328 deliveries by previous cesarean we had 12 (0.90%) or 1:111 cases, complicated by intrapartum rupture of the uterus. It was significantly more than in group of deliveries by unscarred uterus (1:16,849 deliveries). Three of 12 ruptures of the uterus were in group by natural way of delivery and 9 cases in group by repeated cesarean, no statistical difference (p>0.05). Out of 12 cases complicated by rupture of the uterus, ten cases were incomplete and two complete rupture of the uterus. Repeated cesarean section by his complications imposes the careful choice of indication for primary cesarean section and by this way make maternal mortality and morbidity significantly lower, specially in the light of the fact

To define the amount of opioid analgesics prescribed and consumed after discharge after cesarean delivery. We conducted a survey at six academic medical centers in the United States from September 2014 to March 2016. Women who had undergone a cesarean delivery were contacted by phone 2 weeks after discharge and participated in a structured interview about the opioid prescription they received on discharge and their oral opioid intake while at home. A total of 720 women were enrolled; of these, 615 (85.4%) filled an opioid prescription. The median number of dispensed opioid tablets was 40 (interquartile range 30-40), the median number consumed was 20 (interquartile range 8-30), and leftover was 15 (interquartile range 3-26). Of those with leftover opioids, 95.3% had not disposed of the excess medication at the time of the interview. There was an association between a larger number of tablets dispensed and the number consumed independent of patient characteristics. The amount of opioids dispensed did not correlate with patient satisfaction, pain control, or the need to refill the opioid prescription. The amount of opioid prescribed after cesarean delivery generally exceeds the amount consumed by a significant margin, leading to substantial amounts of leftover opioid medication. Lower opioid prescription correlates with lower consumption without a concomitant increase in pain scores or satisfaction.

Late preterm birth (LPB) is increasingly common and associated with higher morbidity and mortality than term birth. Yet, little is known about the influence of previous cesarean section (PCS) and the occurrence of LPB in subsequent pregnancies. We aim to evaluate this association along with the potential mediation by cesarean sections in the current pregnancy. We use population-based birth registry data (2005-2012) to establish a cohort of live born singleton infants born between 34 and 41 gestational weeks to multiparous mothers. PCS was the primary exposure, LPB (34-36 weeks) was the primary outcome, and an unplanned or emergency cesarean section in the current pregnancy was the potential mediator. Associations were quantified using propensity weighted multivariable Poisson regression, and mediating associations were explored using the Baron-Kenny approach. The cohort included 481,531 births, 21,893 (4.5%) were LPB, and 119,983 (24.9%) were predated by at least one PCS. Among mothers with at least one PCS, 6307 (5.26%) were LPB. There was increased risk of LPB among women with at least one PCS (adjusted Relative Risk (aRR): 1.20 (95%CI [1.16, 1.23]). Unplanned or emergency cesarean section in the current pregnancy was identified as a strong mediator to this relationship (mediation ratio = 97%). PCS was associated with higher risk of LPB in subsequent pregnancies. This may be due to an increased risk of subsequent unplanned or emergency preterm cesarean sections. Efforts to minimize index cesarean sections may reduce the risk of LPB in subsequent pregnancies.

Risk factors for preterm delivery have been described, but whether risk factors differ in the context of prior preterm delivery history is less understood. We assessed whether known risk factors were different in women with versus without prior preterm delivery using medical records of the first and second singleton deliveries in 25,820 Utah women (2002–2010). Longitudinal transition models with modified Poisson regression calculated adjusted relative risks and 95% confidence intervals, with ...

Mothers are encouraged to exclusively breastfeed for the first 6 months. However, cesarean delivery rates have increased worldwide, which may affect breastfeeding. Research aim: This study aimed to determine the potential effects of cesarean delivery on breastfeeding practices and breastfeeding duration. This was a 6-month cohort study extracted from a 24-month prospective cohort study of mother-infant pairs in three communities in Hunan, China. Data about participants' characteristics, delivery methods, breastfeeding initiation, use of formula in the hospital, exclusive breastfeeding, and any breastfeeding were collected at 1, 3, and 6 months following each infant's birth. The chi-square test, logistic regression model, and Cox proportional hazard regression model were used to examine the relationship between breastfeeding practices and cesarean delivery. The number of women who had a cesarean delivery was 387 (40.6%), and 567 (59.4%) women had a vaginal delivery. The exclusive breastfeeding rates at 1, 3, and 6 months were 80.2%, 67.4%, and 21.5%, respectively. Women who had a cesarean delivery showed a lower rate of exclusive breastfeeding and any breastfeeding than those who had a vaginal delivery ( p cesarean delivery was related with using formula in the hospital and delayed breastfeeding initiation. Cesarean delivery also shortened the breastfeeding duration (hazard ratio = 1.40, 95% confidence interval [1.06, 1.84]). Healthcare professionals should provide more breastfeeding skills to women who have a cesarean delivery and warn mothers about the dangers of elective cesarean section for breastfeeding practices.

The incidence of twin gestation has increased markedly over the past decades, mostly because of increased use of assisted reproductive technologies. Twin pregnancies are at increased risk of preterm delivery (i.e. birth before 37 weeks of gestation). Multiple gestations therefore account for 2...... sequelae such as abnormal neurophysiological development in early childhood and underachievement in school. Several treatment modalities have been proposed in singleton high-risk pregnancies. The mechanism of initiating labour may, however, be different in singleton and twin gestations.

Mode of delivery at first childbirth largely determines mode of delivery at subsequent births, so it is particularly important to understand risk factors for cesarean delivery at first childbirth. In this study, we investigated risk factors for cesarean delivery among nulliparous women, with focus on the association between labor induction and cesarean delivery. A prospective cohort study of 2851 nulliparous women with singleton pregnancies who attempted vaginal delivery at hospitals in Pennsylvania, 2009-2011, was conducted. We used nested logistic regression models and multiple mediational analyses to investigate the role of three groups of variables in explaining the association between labor induction and unplanned cesarean delivery-the confounders of maternal characteristics and indications for induction, and the mediating (intrapartum) factors-including cervical dilatation, labor augmentation, epidural analgesia, dysfunctional labor, dystocia, fetal intolerance of labor, and maternal request of cesarean during labor. More than a third of the women were induced (34.3%) and 24.8% underwent cesarean delivery. Induced women were more likely to deliver by cesarean (35.9%) than women in spontaneous labor (18.9%), unadjusted OR 2.35 (95% CI 1.97-2.79). The intrapartum factors significantly mediated the association between labor induction and cesarean delivery (explaining 76.7% of this association), particularly cervical dilatation cesarean delivery after labor induction among nulliparous women is attributable mainly to lower cervical dilatation at hospital admission and higher rates of labor complications. © 2017 Wiley Periodicals, Inc.

OBJECTIVE: To estimate the incidence of incisional hernias requiring surgical repair after cesarean delivery over a 10-year period. METHODS: This population- and register-based cohort study identified all women in Denmark with no history of previous abdominal surgery who had a cesarean delivery between 1991 and 2000. The cohort was followed from their first until 10 years after their last cesarean delivery within the inclusion period or until the first of the following events: hernia repair, ...

The objective of the study was to determine predictors of cesarean delivery morbidity associated with massive obesity. This was an institutional review board-approved retrospective study of massively obese women (body mass index, > or = 50 kg/m(2)) undergoing cesarean delivery. Bivariable and multivariable analyses were used to assess the strength of association between wound complication and various predictors. Fifty-eight of 194 patients (30%) had a wound complication. Most (90%) were wound disruptions, and 86% were diagnosed after hospital discharge (median postoperative day, 8.5; interquartile range, 6-12). Subcutaneous drains and smoking, but not labor or ruptured membranes, were independently associated with wound complication after controlling for various confounders. Vertical abdominal incisions were associated with increased operative time, blood loss, and vertical hysterotomy. Women with a body mass index > or = 50 kg/m(2) have a much greater risk for cesarean wound complications than previously reported. Avoidance of subcutaneous drains and increased use of transverse abdominal wall incisions should be considered in massively obese parturients to reduce operative morbidity. Published by Mosby, Inc.

Human biologic evolution involves a compromise between the physical adaptations for bipedalism with effects on birthing success and the much later increases in encephalization of our species. Much of what comes to define life history parameters like gestation length, and brain and birth weight in our species is best understood from this evolutionary perspective. Human populations have been dealing with the obstetric dilemma for many hundreds of thousands of years and modern biomedicine, using techniques like cesarean sections, has alleviated, but not eliminated, birthing as a "scar" of human evolution. If women begin to demand access to universal cesarean delivery, what will the outcome be for the future of human evolution? We can only speculate on the social, biologic, and demographic costs of this transition.

To evaluate the association between documentation of estimated fetal weight, and its value, with cesarean delivery. This was a secondary analysis of a multicenter observational cohort of 115,502 deliveries from 2008 to 2011. Data were abstracted by trained and certified study personnel. We included women at 37 weeks of gestation or greater attempting vaginal delivery with live, nonanomalous, singleton, vertex fetuses and no history of cesarean delivery. Rates and odds ratios (ORs) were calculated for women with ultrasonography or clinical estimated fetal weight compared with women without documentation of estimated fetal weight. Further subgroup analyses were performed for estimated fetal weight categories (less than 3,500, 3,500-3,999, and 4,000 g or greater) stratified by diabetic status. Multivariable analyses were performed to adjust for important potential confounding variables. We included 64,030 women. Cesarean delivery rates were 18.5% in the ultrasound estimated fetal weight group, 13.4% in the clinical estimated fetal weight group, and 11.7% in the no documented estimated fetal weight group (Pcesarean delivery was 1.44 (95% confidence interval [CI] 1.31-1.58, Pcesarean delivery. When ultrasound estimated fetal weight was 4,000 g or greater, the adjusted OR was 2.15 (95% CI 1.55-2.98, Pdelivery at term, documentation of estimated fetal weight (obtained clinically or, particularly, by ultrasonography) was associated with increased odds of cesarean delivery. This relationship was strongest at higher fetal weight estimates, even after controlling for the effects of birth weight and other factors associated with increased cesarean delivery risk.

During the study period (1988–2005 there were 200,012 deliveries by 76,985 women at our medical center; 16,365 of them had a primary CS, of which 7429 women delivered a singleton infant after the primary CS, met the inclusion criteria, were included in our study, and were followed for four consecutive deliveries. Patients were divided into three study groups according to the outcome of their consecutive delivery after the primary CS: VBAC (n = 3622, elective CS (n = 1910, or an urgent CS (n = 1897. Survival analysis models were used to investigate the effect of the urgency of CS and the numbers of pregnancy predating the primary CS on peripartum complications.Results: Women who failed a trial of labor had a higher rate of uterine rupture than those who had a VBAC. Patients who delivered by CS had a higher rate of endometritis than those giving birth vaginally. The rate of cesarean hysterectomy and transfer to other departments increased significantly at the fourth consecutive surgery (P = 0.02 and P = 0.003, respectively.

Full Text Available The aim of the research – assess risk factors for very preterm delivery in the Omsk region. Materials and methods. The main group comprised women with very preterm delivery (n = 64; сomparison group – pregnant women with a threat of interruption in terms of 22-27 weeks and successful preserving therapy (n = 63; control group – pregnant women in whom this pregnancy was taking place without the threat of interruption (n = 62. Results. Risk factors for very preterm delivery were bacterial vaginosis, specific vaginitis, kidney disease and the threat of interruption. There was a significant lead in streptococci (32.3 ± 5.8 %, especially group B (19.0 ± 4.9 % in the main group. The risk factor for very preterm delivery was infectious viral diseases transferred during pregnancy, observed in 12.7 ± 4.2 % of women in the main group, in 7.8 ± 3.3 % in the comparison group (p < 0.01 and in 4.8 ± 2,7 % – control (p < 0,001. In the main group, placental insufficiency was 2 times more common than in the comparison group and 13 times than in the control group. Every sixth pregnant of the main group had manifestations of gestosis. Such complications of gestation as the premature detachment of the normally inserted placenta (7.8 ± 3.3 % and inborn malformations of a fruit (1.6 ± 1.6 % were observed only in the main group. Conclusion. The results of the research and literature data showed that the significant influence on the level of very early premature births is due to: the age of the parents, the abuse of nicotine, alcohol, drugs, abortion, preterm birth, urinary tract and genital tract infections, severe somatic diseases, multiple pregnancies. In the structure of complications of gestation during miscarriages, placental insufficiency predominates, the threat of abortion, fetal growth retardation, and polyhydramnios.

Compared to vaginal delivery, women undergoing cesarean delivery are at increased risk of postpartum hemorrhage. Management approaches may differ between those undergoing prelabor cesarean delivery compared to intrapartum cesarean delivery. We examined surgical interventions, blood component use, and maternal outcomes among those experiencing severe postpartum hemorrhage within the two distinct cesarean delivery cohorts. We performed secondary analyses of data from two cohorts who underwent prelabor cesarean delivery or intrapartum cesarean delivery at a tertiary obstetric center in the United States between 2002 and 2012. Severe postpartum hemorrhage was classified as an estimated blood loss ≥1500mL or receipt of a red blood cell transfusion up to 48h post-cesarean delivery. We examined blood component use, medical and surgical interventions and maternal outcomes. The prelabor cohort comprised 269 women and the intrapartum cohort comprised 278 women. In the prelabor cohort, one third of women received red blood cells intraoperatively or postoperatively, respectively. In the intrapartum cohort, 18% women received red blood cells intraoperatively vs. 44% postoperatively (Pcesarean delivery had the highest rates of morbidity, with 18% requiring hysterectomy and 16% requiring intensive care admission. Our findings provide a snapshot of contemporary transfusion and surgical practices for severe postpartum hemorrhage management during cesarean delivery. To determine optimal transfusion and management practices in this setting, large pragmatic studies are needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

To evaluate the efficacy and safety of external cephalic version (ECV) among women with previous cesarean delivery. A retrospective study was conducted using data for women with previous cesarean delivery and breech presentation who underwent ECV at or after 36 weeks of pregnancy during 2011-2016. For every case, two multiparous women without previous cesarean delivery who underwent ECV and were matched for age and pregnancy duration were included. Characteristics and outcomes were compared between groups. ECV was successful for 32 (84.2%) of 38 women with previous cesarean delivery and 62 (81.6%) in the control group (P=0.728). Multivariate regression analysis confirmed that previous cesarean was not associated with ECV success (odds ratio 1.89, 95% confidence interval 0.19-18.47; P=0.244). Successful vaginal delivery after successful ECV was reported for 19 (59.4%) women in the previous cesarean delivery group and 52 (83.9%) in the control group (Pcesarean delivery. To avoid a repeat cesarean delivery, ECV can be offered to women with breech presentation and previous cesarean delivery who are otherwise eligible for a trial of labor. © 2017 International Federation of Gynecology and Obstetrics.

Risk factors for post-cesarean wound infection, but not disruption, are well-described in the literature. The primary objective of this study was to identify risk factors for non-infectious post-cesarean wound disruption. Secondary analysis was conducted using data from a single-center randomized controlled trial of staple versus suture skin closure in women ≥24 weeks' gestation undergoing cesarean delivery. Wound disruption was defined as subcutaneous skin or fascial dehiscence excluding primary wound infections. Composite wound morbidity (disruption or infection) was examined as a secondary outcome. Patient demographics, medical co-morbidities, and intrapartum characteristics were evaluated as potential risk factors using multivariable logistic regression. Of the 398 randomized patients, 340, including 26 with disruptions (7.6%) met inclusion criteria and were analyzed. After multivariable adjustments, African-American race (aOR 3.9, 95% CI 1.1-13.8) and staple - as opposed to suture - wound closure (aOR 5.4, 95% CI 1.8-16.1) remained significant risk factors for disruption; non-significant increases were observed for body mass index ≥30 (aOR 2.1, 95% CI 0.6-7.5), but not for diabetes mellitus (aOR 0.9, 95% CI 0.3-2.9). RESULTS for composite wound morbidity were similar. Skin closure with staples, African-American race, and considering the relatively small sample size, potentially obesity are associated with increased risk of non-infectious post-cesarean wound disruption.

The doctor-lawyer perspective that we discuss is a maternal refusal to consent to a cesarean delivery for a fetal indication in June 2011. Despite repeated information of the risks during a three-week hospitalization for pre-eclampsia, after being assured of the proper understanding of the seriousness of the situation by the patient and spouse, and after consideration to transfer to another hospital, the reiterated refusal led to a late fetal extraction resulting in term stillbirth.

To assess whether cesarean delivery changes the natural position of the uterus. In this retrospective Institutional Review Board-approved cohort study, we conducted a search of our university gynecologic ultrasonography (US) database. Patients with transvaginal US images before and after either vaginal or cesarean delivery between 2012 and 2015 were included. Women with prior cesarean delivery were excluded. Two readers independently measured antepartum and postpartum flexion angles between the longitudinal axis of the uterine body and the cervix. We calculated intraclass correlation coefficients to measure inter-reader agreement. Antepartum and postpartum uterine flexion angles were compared between patients with vaginal and cesarean delivery. We included 173 patients (107 vaginal and 66 cesarean delivery). The mean interval between scans ± SD was 18 ± 10 months. Inter-reader agreement for flexion angles was almost perfect (intraclass correlation coefficients: antepartum, 0.939; postpartum, 0.969; both P cesarean delivery (154.8° ± 45.7°) versus vaginal delivery (145.8° ± 43.7°; P = .216). Mean postpartum flexion angles were higher after cesarean delivery (180.4° ± 51.2°) versus vaginal delivery (152.8° ± 47.7°; P = .001. Differences in antepartum and postpartum flexion angles between cesarean and vaginal delivery were statistically significant (25.6° versus 7.0°; P = .027). Cesarean delivery can change the uterine flexion angle to a more retroflexed position. Therefore, all women with a history of cesarean delivery should undergo a transvaginal US examination before any gynecologic surgery or intrauterine device placement to reduce the possibility of surgical complications. © 2017 by the American Institute of Ultrasound in Medicine.

To determine whether the risk for uterine rupture is increased in women attempting vaginal birth after multiple cesarean deliveries. We conducted a prospective multicenter observational study of women with prior cesarean delivery undergoing trial of labor and elective repeat operation. Maternal and perinatal outcomes were compared among women attempting vaginal birth after multiple cesarean deliveries and those with a single prior cesarean delivery. We also compared outcomes for women with multiple prior cesarean deliveries undergoing trial of labor with those electing repeat cesarean delivery. Uterine rupture occurred in 9 of 975 (0.9%) women with multiple prior cesarean compared with 115 of 16,915 (0.7%) women with a single prior operation (P = .37). Multivariable analysis confirmed that multiple prior cesarean delivery was not associated with an increased risk for uterine rupture. The rates of hysterectomy (0.6% versus 0.2%, P = .023) and transfusion (3.2% versus 1.6%, P cesarean deliveries compared with women with a single prior cesarean delivery attempting trial of labor. Similarly, a composite of maternal morbidity was increased in women with multiple prior cesarean deliveries undergoing trial of labor compared with those having elective repeat cesarean delivery (odds ratio 1.41, 95% confidence interval 1.02-1.93). A history of multiple cesarean deliveries is not associated with an increased rate of uterine rupture in women attempting vaginal birth compared with those with a single prior operation. Maternal morbidity is increased with trial of labor after multiple cesarean deliveries, compared with elective repeat cesarean delivery, but the absolute risk for complications is small. Vaginal birth after multiple cesarean deliveries should remain an option for eligible women. II-2.
To assess obstetricians' perceptions surrounding cesarean delivery rates in Turkey. The present cross-sectional descriptive study was performed between May 1 and June 30, 2016. Practicing obstetricians with contact details known by the researchers and those attending a conference in Turkey were asked to complete a self-administered questionnaire that collected demographic data and information on participants' opinions, beliefs, knowledge, attitudes, and practices related to cesarean delivery. There were 100 obstetricians who responded to the survey. Awareness of high cesarean delivery rates was reported by 96 (96%) participants and 95 (95%) respondents said they were supportive of efforts to reduce it. There were 60 (60%), 83 (83%), and 100 (100%) participants aware of associations between high cesarean delivery rates and increased maternal and infant mortality; increased risk of uterine rupture; and increased risk of placenta previa, placenta accreta, and emergency cesarean hysterectomy, respectively. The most commonly reported reason for high cesarean delivery rates was high compensation costs during medical litigation legal proceedings, reported by all 100 (100%) participants. Participants were generally aware of the risks associated with high cesarean delivery rates. The results suggest that the greatest concern among obstetricians who perform cesarean deliveries was malpractice litigation. © 2017 International Federation of Gynecology and Obstetrics.
Full Text Available Preterm labour and prematurity are still a main cause of perinatal morbidity nowadays. The aim of our study was to assess the role of MMP-8 as a predictive marker of preterm delivery. Four groups of patients were involved to the study: I - pregnant women at 24-34 weeks of gestation with any symptoms of threatened preterm labour; II - threatened preterm labour patients between 24-34 weeks of gestation; III - preterm vaginal delivery patients; IV - healthy term vaginal delivery patients. Serum concentration of total MMP-8 was measured using two enzyme-linked immunosorbent assays. There were no significant differences in the median concentrations of total MMP-8 between physiological pregnancy and threatened preterm labour patients with existing uterine contractility. No significant differences of total MMP-8 were either found between healthy term and preterm labouring patients. The studies on a larger population are needed to reject the hypothesis that preterm labour is connected with increased MMP-8 plasma concentrations of women in preterm labour and threatened preterm delivery.

This study takes a lifecourse approach to understanding the factors contributing to delivery methods in the US by identifying preconception and pregnancy-related determinants of medically indicated and non-medically indicated cesarean section (C-section) deliveries. Data are from the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative, population-based survey of women delivering a live baby in 2001 (n = 9,350). Three delivery methods were examined: (1) vaginal delivery (reference); (2) medically indicated C-section; and (3) non-medically indicated C-sections. Using multinomial logistic regression, we examined the role of sociodemographics, health, healthcare, stressful life events, pregnancy complications, and history of C-section on the odds of medically indicated and non-medically indicated C-sections, compared to vaginal delivery. 74.2 % of women had a vaginal delivery, 11.6 % had a non-medically indicated C-section, and 14.2 % had a medically indicated C-section. Multivariable analyses revealed that prior C-section was the strongest predictor of both medically indicated and non-medically indicated C-sections. However, we found salient differences between the risk factors for indicated and non-indicated C-sections. Surgical deliveries continue to occur at a high rate in the US despite evidence that they increase the risk for morbidity and mortality among women and their children. Reducing the number of non-medically indicated C-sections is warranted to lower the short- and long-term risks for deleterious health outcomes for women and their babies across the lifecourse. Healthcare providers should address the risk factors for medically indicated C-sections to optimize low-risk delivery methods and improve the survival, health, and well-being of children and their mothers.

The United States is with 37,451 home births in 2014 the country with the largest absolute number of home births among all developed countries. The purpose of this study was to examine the occurrence and risks of a 5-minute Apgar score of zero and neonatal seizures or serious neurologic dysfunction in women with a history of prior cesarean delivery for planned home vaginal birth after cesarean (VBAC), compared to hospital VBAC and hospital birth cesarean deliveries for term normal weight infants in the United States from 2007-2014. We report in this study outcomes of women who had one or more prior cesarean deliveries and included women who had a successful vaginal birth after a trial of labor after cesarean (TOLAC) at home and in the hospital, and a repeat cesarean delivery in the hospital. We excluded preterm births (cesarean deliveries, a significantly higher incidence and risk of a 5-minute Apgar score of 0 of 1 in 890 (11.24/10,000, relative risk 9.04, 95% confidence interval 4-20.39, p<.0001) and an incidence of neonatal seizures or severe neurologic dysfunction of 1 in 814 (Incidence: 12.27/10,000, relative risk 11.19, 95% confidence interval 5.13-24.29, p<.0001). Because of the significantly increased neonatal risks, obstetric providers should therefore not offer or perform planned home TOLACs and for those desiring a VBAC should strongly recommend a planned TOLAC in the appropriate hospital setting. We emphasize that this stance should be accompanied by effective efforts to make TOLAC available in the appropriate hospital setting.

To explore the appropriate approach of delivery after cesarean section of Uyghur women in primary hospitals in Xinjiang Uyghur Autonomous Region. A total of 5 154 women delivered in Luopu County People Hospital, Hetian Prefecture, Xinjiang Uyghur Autonomous Region from January 2011 to December 2012. Among them, 178 Uyghur women had cesarean section history. The interval between the previous cesarean section and this delivery varied from 1 year to 17 years. The number of cases attempting vaginal labor and the indications of the previous cesarean section were recorded. The indications for the second cesarean section were analyzed. The gestational weeks at delivery, blood loss in 2 hours after delivery, neonatal birth weight, newborn asphyxia, the rate of postpartum fever (≥ 38 °C) and hospitalization days were compared between the two approaches of delivery. (1) Among the 178 cases, 119 cases attempted vaginal labor, the rate of attempting vaginal labor was 66.9% (119/178). A total of 113 cases succeeded in vaginal delivery (the vaginal delivery group), with the successful rate of attempting vaginal delivery of 95.0% (113/119), and the successful rate of vaginal delivery was 63.5% (113/178). For those 119 women succeeded in vaginal delivery, the indications of the previous cesarean sections were as following: pregnancy complications (68.1%, 81/119), macrosomia(5.0%, 6/119), dystocia (14.3%, 17/119), pregnancies complicated with other diseases (5.0%, 6/119) and cesarean section on maternal request (7.6%, 9/119). (2) 15 cases in the cesarean section group had postpartum hemorrhage, with the incidence of 13.3% (15/113). The mean total labor time was (507 ± 182) minutes. 6 cases attempting vaginal delivery failed and turned to cesarean section. (3) 59 cases received the second cesarean section (the cesarean section group). The rate of second cesarean section was 33.1% (59/178). The indications of the second cesarean section were as following: contracted pelvis (5%, 3

Knowledge of hospital-specific average cesarean delivery operative times, and factors influencing length of surgery, can serve as a guide for anesthesiologists when choosing the optimal anesthetic technique. The aim of this study was to determine operative times and the factors influencing those times for cesarean delivery. We conducted a retrospective review of all 1348 cesarean deliveries performed at an academic hospital in 2011. The primary outcome was mean operative time for first, second, third and fourth or more cesarean deliveries. The secondary goal was to identify factors influencing operative time. Variables included age, body mass index, previous surgery, gestational age, urgency of cesarean delivery, anesthesia type, surgeon's seniority, layers closed, and performance of tubal ligation. Mean (standard deviation) operative times for first (n=857), second (n=353), third (n=108) and fourth or more (n=30) cesarean deliveries were 56 (19), 60 (19), 69 (28) and 82 (31) minutes, respectively (P cesarean delivery or the presence of other factors that could increase operative time may warrant catheter-based anesthetic techniques or the addition of adjunctive medications to prolong spinal anesthetic block. Institutional and individual surgeon factors may play an even more important role in determining surgical time. Copyright © 2018 Elsevier Ltd. All rights reserved.
Full Text Available Background & objective: Although delivering with Cesarean method is preferred in limited cases which has dangerous effects on child or mother's health, rate of cesarean is increasing vastly nowadays. The main purpose of this study was to explore Social, Cultural and Demographic factors related to this phenomenon among pregnant women of Shiraz. Materials & Methods: In this study 600 pregnant women residing in Shiraz were selected using Lin cross size of sample (multistage sampling. Data were collected through the validated questionnaire and analyzed with SPSS software by multi-variables logistic regression and X2 techniques. Results: Research hypotheses about significant relation among these factors (age, age of marriage, education, spouse’s education, occupational status, place of birth, social class status, previous childbirth method, record of barrenness, place of previous childbirth, place of pregnant care, record of cesarean in family and attitude toward cesarean with choice of cesarean have been approved. Research hypotheses about month of pregnancy, number of pregnancy and knowledge of delivery method and cesarean have been rejected. Conclusion: Due to significant positive attitude of women's towards the cesarean, rather than normal delivery, it is necessary to inform them about the advantages of normal delivery and health hazard which might cause by Cesarean to the mother and child. The change of women's attitude about cesarean is needed to avoid further complication.

Objective. To identify potential risk factors for cesarean delivery following labor induction in multiparous women at term. Methods. We conducted a retrospective case-control study. Cases were parous women in whom the induction of labor had resulted in a cesarean delivery. For each case, we used the data of two successful inductions as controls. Successful induction was defined as a vaginal delivery after the induction of labor. The study was limited to term singleton pregnancies with a child...

Objective To estimate the association between maternal super obesity (body mass index [BMI] ≥ 50 kg/m(2)) and neonatal morbidity among neonates born via cesarean delivery (CD). Methods Retrospective cohort of singleton neonates delivered via CD ≥ 37 weeks in the Maternal-Fetal Medicine Unit Cesarean Registry. Maternal BMI at delivery was stratified as 18.5 to 29.9 kg/m(2), 30 to 39.9 kg/m(2), 40 to 49.9 kg/m(2), and ≥ 50 kg/m(2). Primary outcomes included acute (5-minute Apgar score neonatal injury, and/or transient tachypnea of the newborn) and severe (grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, seizure, respiratory distress syndrome, hypoxic ischemic encephalopathy, meconium aspiration, ventilator support ≥ 2 days, sepsis and/or neonatal death) neonatal morbidity. Odds of neonatal morbidity were estimated for each BMI category adjusting for clinical and operative characteristics. Results Of 41,262 maternal-neonatal dyads, 36% of women were nonobese, 49% had BMI of 30 to 39.9 kg/m(2), 12% had BMI of 40 to 49.9 kg/m(2), and 3% were super obese. Compared with nonobese women, super obese women had twofold odds of acute (5 vs. 10%; adjusted odds ratio [aOR]: 1.81, 95% confidence interval [CI]: 1.59-2.73) and severe (3 vs. 6%; aOR: 2.08; 95% CI: 1.59-2.73) neonatal morbidity. Conclusion Among term infants delivered via CD, maternal super obesity is associated with increased risk of neonatal morbidity. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

International rates of operative delivery are consistently higher than the World Health Organization determined is appropriate. This suggests that factors other than clinical indications contribute to cesarean section. Data presented here are from interviews with 115 mothers on the postnatal ward of a hospital in Northeast England during February 2006 to March 2009 after the women underwent either unscheduled or scheduled cesarean childbirth. Using thematic content analysis, we found women's accounts of their experiences largely portrayed cesarean section as everything that they had wanted to avoid, but necessary given their situations. Contrary to popular suggestion, the data did not indicate impersonalized medical practice, or that cesareans were being performed 'on request.' The categorization of cesareans into 'emergency' and 'elective' did not reflect maternal experiences. Rather, many unscheduled cesareans were conducted without indications of fetal distress and most scheduled cesareans were not booked because of 'choice.' The authoritative knowledge that influenced maternal perceptions of the need to undergo operative delivery included moving forward from 'prolonged' labor and scheduling cesarean as a prophylactic to avoid anticipated psychological or physical harm. In spontaneously defending themselves against stigma from the 'too posh to push' label that is currently common in the media, women portrayed debate on the appropriateness of cesarean childbirth as a social critique instead of a health issue. The findings suggest the 'need' for some cesareans is due to misrecognition of indications by all involved. The factors underlying many cesareans may actually be modifiable, but informed choice and healthful outcomes are impeded by lack of awareness regarding the benefits of labor on the fetal transition to extrauterine life, the maternal desire for predictability in their parturition and recovery experiences, and possibly lack of sufficient experience for

A continuous rise in the rate of cesarean deliveries has been reported in many countries over recent decades. This trend has prompted the emergence of a debate on the risks and benefits associated with cesarean section. The present study was designed to estimate cesarean section rates over time during the period between 2000 and 2010 in Peru and to present outcomes for each mode of delivery. This is a secondary analysis of a large database obtained from the Perinatal Information System, which includes 570,997 pregnant women and their babies from 43 Peruvian public health facilities in three geographical regions: coast, highlands, and jungle. Over 10 years, 558,901 women delivered 563,668 infants weighing at least 500 g. The cesarean section rate increased from 25.5% in 2000 to 29.9% in 2010 (26.9% average; P cesarean than vaginal deliveries (P cesarean section (P cesarean section group than in the vaginal delivery group. Data suggest that cesarean sections are associated with adverse pregnancy outcomes. PMID:24124393
Objectives. I examined the relationship between insurance coverage, which may influence physician incentives and maternal choices, and cesarean delivery before labor. Methods. I analyzed hospital discharge data for mothers without previous cesarean deliveries in New Jersey between 2004 and 2007, with adjustment for maternal age, race, marital status, and maternal, fetal, and placental conditions. Results. Nearly 1 in 7 women (13.9%) had a cesarean delivery without laboring. Insurance status was strongly associated with cesarean birth. Women insured by Medicaid (adjusted relative risk [ARR] = 0.88; 95% confidence interval [CI] = 0.84, 0.91) or self-paying (ARR = 0.81; 95% CI = 0.78, 0.85) had a significantly lower likelihood, and women insured by BlueCross (ARR = 1.06; 95% CI = 1.03, 1.09) or standard commercial plans (ARR = 1.06; 95% CI = 1.02, 1.10) had a significantly higher likelihood of cesarean delivery than did women insured by commercial health maintenance organizations. These associations persisted in subsets restricted to lower-risk women and in qualitative sensitivity analyses for a hypothetical single, binary, unmeasured confounder. Conclusions. Insurance status has a small, independent impact on whether a woman without a previous cesarean delivery proceeds to labor or has a cesarean delivery without labor. PMID:21940911
In 2011, one in three women who gave birth in the United States did so by cesarean delivery. Cesarean birth can be life-saving for the fetus, the mother, or both in certain cases. However, the rapid increase in cesarean birth rates from 1996 to 2011 without clear evidence of concomitant decreases in maternal or neonatal morbidity or mortality raises significant concern that cesarean delivery is overused. Variation in the rates of nulliparous, term, singleton, vertex cesarean births also indicates that clinical practice patterns affect the number of cesarean births performed. The most common indications for primary cesarean delivery include, in order of frequency, labor dystocia, abnormal or indeterminate (formerly, nonreassuring) fetal heart rate tracing, fetal malpresentation, multiple gestation, and suspected fetal macrosomia. Safe reduction of the rate of primary cesarean deliveries will require different approaches for each of these, as well as other, indications. For example, it may be necessary to revisit the definition of labor dystocia because recent data show that contemporary labor progresses at a rate substantially slower than what was historically taught. Additionally, improved and standardized fetal heart rate interpretation and management may have an effect. Increasing women's access to nonmedical interventions during labor, such as continuous labor and delivery support, also has been shown to reduce cesarean birth rates. External cephalic version for breech presentation and a trial of labor for women with twin gestations when the first twin is in cephalic presentation are other of several examples of interventions that can contribute to the safe lowering of the primary cesarean delivery rate.

Urinary bladder injury is a rare complication during cesarean delivery. Little is known on maternal outcome following this injury. To evaluate short and long-term maternal outcome following bladder injury during cesarean delivery. A retrospective case series of all pregnancies complicated by full-thickness bladder injury during cesarean delivery in a single university affiliated tertiary medical center (August 2007-June 2016). Data on demographics, labor and surgery parameters, postpartum sequelae, and cystography were collected and reviewed by study personnel. Short-term maternal outcome included catheterization period, cystography results (if performed), any febrile illness and/or need for second operation prior to maternal discharge. Long term maternal outcome was obtained by searching our urology departmental and ambulatory database for follow up for all women. Univariate analysis was used to compare maternal outcome following first or repeat cesarean delivery. Of 17,326 cesarean deliveries performed during study period, 81 (0.47%) were complicated by bladder injury. Of them, 8 cases (9.9%) occurred during primary cesarean delivery (overall risk in primary cesarean 0.07%). Of the other 73 cases that followed repeated cesarean, adhesions were documented in 55 (75.3%) of them. Six cases (8.2%) had placenta accreta. Bladder injury occurred at peritoneal entry in 55 (67.9%) cases, and involved the bladder dome in 49 (60.5%) of them. Injury was diagnosed during cesarean delivery in all but 3 women, in whom abdominal pain and bloating prompted evaluation on first to third postoperative day. All 3 underwent re-laparotomy with bladder closure without further adverse sequelae. Cystography was performed in 35 patients on median postoperative day 8 (6-11 days). Eleven patients had abnormal findings as follows: 5 urinary leakage, 4 bladder wall irregularity and two urinary reflux. Two of the 11 patients (18%) required additional interventions: One patient required

To explain the variation in decision-to-delivery intervals in emergency cesarean sections in Norway. A seven-month prospective registration of all emergency cesareans provided by 24 maternity units. The clinician in charge filled in a predesigned form for each delivery that obtained detailed information about obstetric history, the pregnancy, indication, the date and time of delivery, decision-to-delivery interval, seniority of the surgeon, and neonatal outcome until hospital discharge. To take account of the clustered nature of our observations, data were analyzed by multilevel regression. 1,511 singleton emergency cesarean sections with known decision-to-delivery interval were included. The average decision-to-delivery interval for all emergency cesarean sections was 52.4 min, for acute cesarean sections 58.7 min, and for urgent emergency operations 11.8 min. Most of the decision-to-delivery interval variation was at patient level, not between departments. Several significant decision-to-delivery interval predictors were identified: 1. abruptio placentae (-54 min), umbilical cord prolapse (-37 min), and fetal stress (-35 min); 2. general anesthesia (versus regional) (-15 min), 3. cesarean sections performed during night-time (-10 min), 4. seniority of the surgeon (-6 min), and 5. cervical opening (for each cm: -6 min). The variance in the decision-to-delivery interval was mainly explained by the different nature of the cesarean sections. The most important predictors, which all acted to reduce decision-to-delivery interval, were the three indications abruptio placentae, cord prolapse, and fetal stress. Sections performed during night-time had significantly reduced decision-to-delivery interval. The size of the maternal units as measured by number of deliveries per year was not a significant predictor.

Although it is likely that childbearing among women with disabilities is increasing, no empirical data have been published on changes over time in the numbers of women with disabilities giving birth. Further, while it is known that women with disabilities are at increased risk of cesarean delivery, temporal trends in cesarean deliveries among women with disabilities have not been examined. To assess time trends in births by any mode and in primary cesarean deliveries among women with physical, sensory, or intellectual/developmental disabilities. We conducted a retrospective cohort study using linked vital records and hospital discharge data from all deliveries in California, 2000-2010 (n = 4,605,061). We identified women with potential disabilities using ICD-9 codes. We used descriptive statistics and visualizations to examine time patterns. Logistic regression analyses assessed the association between disability and primary cesarean delivery, stratified by year. Among all women giving birth, the proportion with a disability increased from 0.27% in 2000 to 0.80% in 2010. Women with disabilities had significantly elevated odds of primary cesarean delivery in each year, but the magnitude of the odds ratio decreased over time from 2.60 (95% CI = 2.25 = 2.99) in 2000 to 1.66 (95% CI = 1.51-1.81) in 2010. Adequate clinician training is needed to address the perinatal care needs of the increasing numbers of women with disabilities giving birth. Continued efforts to understand cesarean delivery patterns and reasons for cesarean deliveries may help guide further reductions in proportions of cesarean deliveries among women with disabilities relative to women without disabilities.

Cesarean delivery is the most commonly performed surgical procedure in the United States, and cesarean rates are increasing. Working with 2009 data from 593 US hospitals nationwide, we found that cesarean rates varied tenfold across hospitals, from 7.1 percent to 69.9 percent. Even for women with lower-risk pregnancies, in which more limited variation might be expected, cesarean rates varied fifteen-fold, from 2.4 percent to 36.5 percent. Thus, vast differences in practice patterns are likely to be driving the costly overuse of cesarean delivery in many US hospitals. Because Medicaid pays for nearly half of US births, government efforts to decrease variation are warranted. We focus on four promising directions for reducing these variations, including better coordination of maternity care, more data collection and measurement, tying Medicaid payment to quality improvement, and enhancing patient-centered decision making through public reporting.

To examine impact of cesarean delivery in first pregnancy on neonatal mortality and morbidity in second pregnancy. Retrospective cohort study using 1995-2002 US birth registration data. Neonatal mortality and morbidity in second pregnancy of cesarean deliveries in the first pregnancy were compared with vaginal deliveries in the first pregnancy. A total of 9,643,175 singleton second births were eligible in the analysis after excluding those with unknown delivery method (1,801,339 with a previous cesarean delivery and 7,841,836 with a previous vaginal delivery). Compared with vaginal delivery group, infants born to mothers with a previous cesarean delivery had increased risks of assisted ventilation (OR=1.47, 95% CI 1.46, 1.49), low Apgar's score (OR=1.14, 95% CI 1.12, 1.17), seizure (OR=1.36, 95% CI 1.27, 1.45), fetal distress (OR=1.46, 95% CI 1.44, 1.47), and asphyxia-related neonatal death (OR=1.40, 95% CI 1.29, 1.52). The association between mode of delivery in first pregnancy and neonatal outcomes in second pregnancy remained the same after excluding women with chronic health problems or adverse birth history and adjusting for potential confounding factors. Cesarean delivery in first pregnancy is associated with increased risks of neonatal morbidity and mortality in second pregnancy. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

clinical utility and is therefore not recommended during pregnancy to help decide the mode of delivery (professional consensus). Use of X-ray pelvimetry to decide about TOLAC is associated with an increase in the repeat cesarean rate without any reduction in the rate of uterine rupture (LE2). It is unnecessary for deciding mode of delivery and for managing labor during TOLAC (grade C). TOLAC should be encouraged for women with a previous vaginal delivery either before or after the cesarean, a favorable Bishop score or spontaneous labor, and for preterm births (grade C). For women with a fetus with an estimated weight of more than 4500 g, especially in the absence of a previous vaginal delivery and those with supermorbid obesity (BMI>50), ERCD must be planned from the outset (grade C). For all of the other clinical situations envisioned (maternal age>35 years, diabetes, morbid obesity, prolonged pregnancy, breech presentation and twin pregnancy), TOLAC is possible but the available data do not allow specific guidelines about the choice of mode of delivery, in view of the low levels of proof (grade C). The decision about planned mode of delivery must be shared by the patient and her physician and made by the 8th month, taking into account the individual risk factors for TOLAC failure and uterine rupture (professional consensus). TOLAC is the preferred choice for women who do not have several risk factors (professional consensus). The availability onsite of an obstetrician and anesthetist must be pointed out to the patient. If the woman continues to prefer a repeat cesarean after adequate information and time to think about it, her preference should be honored (professional consensus). Labor should be induced in woman with a previous cesarean only for medical indications (professional consensus). Induction of labor increases the risk of uterine rupture, which can be estimated at 1% if oxytocin is used and 2% with vaginal prostaglandins (LE2). Mechanical methods of induction

Hospitals and providers are increasingly held accountable for their cesarean delivery rates. In the perinatal quality improvement arena, there is vigorous debate about whether all hospitals can be held to the same benchmark for an acceptable cesarean rate regardless of patient acuity. However, the causes of variation in hospital cesarean delivery rates are not well understood. We sought to evaluate the association and temporal trends between severity of illness at admission and the primary term singleton vertex cesarean delivery rate among hospitals in Washington State. We hypothesized that hospitals with higher patient acuity would have higher cesarean delivery rates and that this pattern would persist over time. In this cross-sectional analysis, we analyzed aggregate hospital-level data for all nonmilitary hospitals in Washington State with ≥100 deliveries/y during federal fiscal years 2010 through 2014 (287,031 deliveries). Data were obtained from the Washington State Comprehensive Hospital Abstract Reporting System, which includes inpatient demographic, diagnosis, procedure, and discharge information derived from hospital billing systems. Age, admission diagnoses and procedure codes were converted to patient-level admission severity-of-illness scores using the All Patient Refined Diagnosis Related Groups classification system. This system is widely used throughout the United States to adjust hospital data for severity of illness. Mean admission hospital-level severity-of-illness scores were calculated for each fiscal year among the term singleton vertex population with no history of cesarean delivery. We used linear regression to evaluate the association between hospital admission severity of illness and the primary term singleton vertex cesarean delivery rate, calculated Pearson correlation coefficients, and compared regression line slopes and 95% confidence intervals for each fiscal year. Hospitals were diverse with respect to delivery volume, level of care

To compare primary indications for cesarean delivery among patients with different female genital mutilation (FGM) status. The present secondary analysis included data from women who underwent trial of labor resulting in cesarean delivery at 28 obstetric centers in six African countries between November 1, 2001, and March 31, 2003. Associations between cesarean delivery indications and FGM status were assessed using descriptive statistics and multivariable multinomial logistic regression. Data from 1659 women (480 patients with no type of FGM and 1179 patients with FGM [any type]) were included; cesarean delivery indications were collapsed into five categories (fetal indications, maternal factors, stage 1 arrest, stage 2 arrest, and other). The incidence of a clear medical indication for cesarean delivery did not differ between the groups (P=0.320). Among patients without a clear indication for cesarean delivery, women with FGM were more likely to have undergone cesarean delivery for maternal factors (adjusted relative risk ratio [aRRR] 3.92, 95% confidence interval [CI] 1.3-11.71), stage 1 arrest (aRRR 7.74, 95% CI 1.33-45.07), stage 2 arrest (aRRR 6.63, 95% CI 3.74-11.73), or other factors (aRRR 2.41, 95% CI 1.04-5.60) rather than fetal factors compared with women who had no type of FGM. Among women with unclear medical indications, FGM was associated with cesarean delivery being performed for maternal factors or arrest disorders. © 2017 World Health Organization; licensed by John Wiley & Sons Ltd on behalf of International Federation of Gynecology and Obstetrics.

The aim of the study was to perform a comparative analysis of complications after vaginal deliveries and cesarean sections and to introduce emotional status of the mother as an indication for a cesarean section. 406 patients after vaginal deliveries and cesarean sections, that took place in the first quarter of 2009, were enrolled into the study. In the studied group of 406 patients, 200 women (49.2%) had cesarean section and 206 women (50.8%) delivered vaginally. In both groups there were no differences in the clinical state of newborns, which were assessed according to the Apgar score, and in umbilical cord blood pH. Hemoglobin concentration evaluated on the second day of puerperium was statistically significantly higher in the group of patients after cesarean section than after vaginal delivery. Episiotomy and laparotomy wound healing complications were observed in 2 (0.97%) and 3 (1.5%) cases, respectively. Due to lack of differences in complication rates between cesarean section and vaginal delivery patients, the emotional status of a pregnant woman should be considered as an indication for cesarean section.

survey of Norwegian obstetricians (n = 716; response rate, 71%) using clinical scenarios. The risk attitude was measured by 6 items from the Jackson Personality Inventory-Revised. RESULTS: The proportion of obstetricians consenting to the cesarean request varied both within and across the scenarios....... The perceived risk of complaints and malpractice litigation was a clear determinant of obstetricians' choice of cesarean in all of the clinical scenarios, whereas no impact was observed for risk attitude. CONCLUSION: Obstetricians' judgments about cesarean request in ambiguous clinical cases vary considerably....... Perceived risk of complaints and litigation is associated with compliance with the requested cesarean....

To estimate the effect of the onset of labor before a primary cesarean delivery on the risk of uterine rupture if vaginal birth after cesarean (VBAC) is attempted in the next pregnancy. Longitudinally linked birth records were used to follow women from a primary cesarean delivery to a trial of labor at term for their next birth. The effects of characteristics of both the trial of labor and primary cesarean deliveries on the risk of uterine rupture were examined. Of 10,160 women who had a trial of labor, 39 (0.38%) had a uterine rupture. Women who were induced or augmented for their trial of labor had a greater relative risk (RR) of uterine rupture (crude RR 4.24, 95% confidence interval [CI] 2.23-8.07). Women whose primary cesarean delivery was planned or followed induction of labor also had an increased risk of uterine rupture (crude RR 2.61, 95% CI 1.24-5.49), and this risk remained after adjustment for other factors. Women with a history of either spontaneous labor or vaginal birth had one uterine rupture for every 460 deliveries; women without this history who required induction or augmentation to proceed with a VBAC attempt had one uterine rupture for every 95 deliveries. Labor before the primary cesarean delivery can decrease the risk of uterine rupture in a subsequent trial of labor. A history of primary cesarean delivery preceded by spontaneous labor is favorable for VBAC. II.

OBJECTIVE: To examine the use of quality control performance charts to analyze cesarean rates nationally. METHODS: Information on cesarean rates was obtained for all 19 Irish maternity hospitals receiving state funding in 2009. All women who underwent cesarean delivery of a live or stillborn infant weighing 500 g or more between January 1 and December 31 were included. Deliveries were classified as elective or emergency. Individual hospitals were not identified in the analysis. RESULTS: The mean rates per hospital of elective and emergency cesarean were 12.9+\\/-2.6% (n=9337) and 13.8+\\/-3.0% (n=9989), respectively-giving an overall mean rate of 26.7+\\/-4.2% (n=19326) per hospital. Cesarean rates were normally distributed. Using a quality control performance chart with a cutoff 2 standard deviations from the mean, 1 hospital was above the normal range for both total and elective cesareans, indicating that its pre-labor obstetric practices warrant clinical review. Another hospital had a mean emergency cesarean rate above the normal range, indicating that its labor ward practices warrant review. CONCLUSION: Quality control performance charts can be used to analyze cesarean rates nationally and, thus, to identify hospitals at which obstetric practices should be reviewed.

To determine neonatal and short term maternal outcomes according to intentional mode of delivery following a cesarean delivery (CD). Women pregnant after CD between January 2000 and December 2007 were categorized according to whether they had an elective repeat CD (ERCD) or a Trial of Labor (TOL). Prognostically equal ERCD and TOL groups were created using the propensity score matching technique. Conditional logistic regression was performed to assess differences in neonatal and maternal outcomes. Women in their second ongoing pregnancy with a history of CD. After ERCD the rates of low 5min Apgar score (OR 0.3, 95%CI 0.2-0.5, p<0.001), meconium aspiration (OR 0.0, 95%CI 0-0.7, p=0.02) and birth trauma (OR 0.08, 95%CI 0.002-0.5, p<0.001) were lower compared to TOL. The rate of transient tachypnoea of the newborn (TTN) appears higher in the ERCD group (OR 1.7, 95%CI 1.0-2.8, p=0.04). Uterine rupture (OR 0.1, 95%CI 0.003-0.8, p=0.02) and hemorrhage (OR 0.6, 95%CI 0.5-0.8, p<0.001) occurred less in the ERCD group. Neonatal and short term maternal morbidity appears to be lower after ERCD than after TOL. Only TTN was seen more often after ERCD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.
Background As part of a National Emergency Obstetric and Newborn Care (EmONC) Needs Assessment, a special study was undertaken in July 2010 to examine the quality of cesarean deliveries in Afghanistan and examine the utility of direct clinical observation as an assessment method in low-resource settings. Methods This cross-sectional assessment of the quality of cesareans at 14 facilities in Afghanistan included a survey of surgeons regarding their routine cesarean practices, direct observation of 29 cesarean deliveries and comparison of observations with facility records for 34 additional cesareans conducted during the 3 days prior to the observation period at each facility. For both observed cases and record reviews, we assessed time intervals between specified points of care-arrival to the ward, first evaluation, detection of a complication, decision for cesarean, incision, and birth. Results All time intervals with the exception of “decision to skin incision” were longer in the record reviews than in observed cases. Prior cesarean was the most common primary indication for all cases. All mothers in both groups observed survived through one hour postpartum. Among newborns there were two stillbirths (7%) in observed births and seven (21%) record reviews. Although our sample is too small to show statistical significance, the difference is noteworthy. In six of the reviewed cesareans resulting in stillbirth, a fetal heart rate was recorded in the operating theater, although four were recorded as macerated. For the two fresh stillbirths, the cesarean surgeries were recorded as scheduled and not urgent. Conclusions Direct observation of cesarean deliveries enabled us to assess a number of preoperative, postoperative, and intraoperative procedures that are often not described in medical records in low resource settings. Comparison of observations with findings from provider interviews and facility records allowed us to infer whether observed practices were typical

The authors evaluated the association between amount and type of alcohol consumed during pregnancy and the risk of preterm delivery and whether the relation differs among very (preterm delivery. The study is based on data of 40......,892 pregnant women included in the first part of the Danish National Birth Cohort. The women completed a computer-assisted telephone interview between December 12, 1997, and December 31, 2000, and delivered a liveborn singleton. Of these women, 1,880 gave birth preterm. Compared with those who abstained during...... pregnancy, the relative risks for preterm delivery among women who consumed from four to less than seven drinks and seven or more drinks per week during pregnancy were 1.15 (95% confidence interval: 0.84, 1.57) and 1.77 (95% confidence interval: 0.94, 3.31), respectively. Below these intake levels...
Full Text Available Uterine atony during cesarean delivery is a serious cause of maternal morbidity and mortality. Management strategies include medical treatment with uterotonic agents, manual compression of the uterus, and interventional or surgical procedures. A novel technique to compress the uterus by wrapping it with an elastic bandage and its outcome in 3 cases of uterine atony during cesarean section are presented. Our novel method of intermittent wrapping of the uterus during cesarean delivery seems to be a successful additional approach in the management of uterine atony during cesarean delivery and may be an alternative treatment option to other compressing procedures in order to avoid high blood loss and last but not least postpartum hysterectomy.

The objective of the study was to compare the prevalence of incontinence disorders in relation with spontaneous vaginal delivery or cesarean section. Two hundred women with spontaneous vaginal deliveries only were compared with 195 women with cesarean deliveries only 10 years after first delivery. When compared with cesarean section, vaginal delivery was associated with an increased frequency of stress urinary incontinence (P = .006) and an increased use of protective pads (P = .008) as well as an increased frequency of fecal urgency (P = .048) and gas incontinence (P = .01). At multivariate regression analysis, mode of delivery showed no significant association with incontinence symptoms other than an increased risk for flatus incontinence in women with a history of obstetric anal sphincter injury (odds ratio 3.1; 95% confidence interval, 1.5 to 8.9). Incontinence symptoms are more common following spontaneous vaginal delivery when compared with cesarean section 10 years after first delivery. However, cesarean section is not associated with a major reduction of anal and urinary incontinence.

Cesarean delivery has increased steadily in the United States over recent decades with significant downstream health consequences. The World Health Organization has endorsed the Robson Ten Group Classification System (TGCS) as a global standard to facilitate analysis and comparison of cesarean delivery rates. Our objective was to apply the TGCS to a nationwide cohort in the United States over a 10-year period. This population-based analysis applied the TGCS to all births in the United States from 2005-2014, recorded in the 2003-revised birth certificate format. Over the study 10-year period 27,044,217 deliveries met inclusion criteria. Five parameters (parity including previous cesarean, gestational age, labor onset, fetal presentation and plurality), identifiable on presentation for delivery, were used to classify all women included into one of ten groups. The overall cesarean rate was 31.6%. Group 3 births (singleton, term, cephalic multiparas in spontaneous labor) were most common, while Group 5 births (those with a previous cesarean) accounted for the most cesarean deliveries increasing from 27% of all cesareans in 2005-06 to over 34% in 2013-14. Breech pregnancies (Groups 6 and 7) had cesarean rates above 90%. Primiparous and multiparous women who had a prelabor cesarean [Groups 2(b) and 4(b)] accounted for over one quarter of all cesarean deliveries. Women with a previous cesarean delivery represent an increasing proportion of cesarean deliveries. Use of the Robson criteria allows standardised comparisons of data and identifies clinical scenarios driving changes in cesarean rates. Hospitals and health organisations can use the TGCS to evaluate quality and processes associated with cesarean delivery. Copyright © 2018 Elsevier Inc. All rights reserved.

To predict the risk of cesarean delivery (CS) for multiparous women who have undergone previous vaginal delivery. A prospective observational study was performed, among multiparous pregnancies that were between 38 and 41 gestational weeks and had a singleton, vertex presentation fetus. Women's physical activity score, obstetric history, intrapartum and postpartum events were assessed. Multivariable logistic regression was used to explore risk factors associated with CS. Of the 245 total 83.7% had spontaneous labor and 16.3% were induced. Seventy-five percent of the induced women required CS, whereas only 19.5% of those with spontaneous labor required CS (pcesarean delivery among previously vaginally delivered women and maternal weight gain, physical activity score, cervical dilatation, and fetal weight are most accurate parameters in the prediction of the risk of CS delivery. Intrapartum CS has an increased risk of maternal morbidity.

Perinatal death, in particular intrapartum stillbirth and short-term neonatal death, as well as neonatal short term and long term morbidity have been associated with the time of day that the birth occurs. Indeed, evening and nighttime deliveries were associated with an increased risk of an adverse perinatal outcome when compared to similar daytime deliveries. Impact of shift change, as well as time of day delivery have been extensively studied in the context of maternal and neonatal complications of cesarean delivery, however, no studies were previously performed on timing of delivery and its effect on the outcome of pregnancies complicated by preterm premature rupture of membranes. Our objective was to compare obstetric, neonatal as well as long-term outcomes between women delivered in the daytime versus nighttime, in singleton gestations whose pregnancies were complicated by preterm premature rupture of membranes. This was a secondary analysis of a trial of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network "A Randomized Clinical Trial of the Beneficial Effects of Antenatal Magnesium Sulfate for the Prevention of Cerebral Palsy". For this analysis, the time of delivery was divided into the daytime, from 07:01 to 19:00, and the nighttime, from 19:01 to 07:00. Epidemiological, obstetric characteristics as well as neonatal and long-term outcomes were compared between deliveries occurring during the daytime versus the nighttime periods. Inclusion criteria consisted of singleton gestations diagnosed with preterm premature rupture of membranes (PPROM). Multifetal gestations and pregnancies with preterm labor without preterm premature rupture of membranes were excluded. A total of 1752 patients met inclusion criteria, 881 delivering during the daytime, while 871 during the nighttime. There were no differences in demographic maternal variables. There were no differences in the number of patients

Objective The objective of this study is to determine the maternal and neonatal morbidity associated with attempting operative vaginal delivery (OVD) compared with the alternative of a laboring repeat cesarean delivery (LRCD) in women attempting a trial of labor after cesarean delivery (TOLAC). Methods This is a secondary analysis of a multicenter prospective study designed to assess perinatal outcomes of OVD in women with a prior uterine scar. The study includes women who attempted TOLAC and reached +2 station with a fully dilated cervix. Composites on neonatal and maternal morbidity were compared between women in whom OVD was attempted and those who underwent LRCD by fitting multivariate logistic regression models. Results In total, 6,489 women attempting TOLAC reached 2+ station with a fully dilated cervix. Of these, 5,640 (86.9%) had a spontaneous vaginal delivery, 762 (11.7%) underwent attempted OVD, and 87 (1.3%) had an LRCD. Compared with attempting OVD, LRCD was associated with greater neonatal morbidity (odds ratio [OR]: 2.41; 95% confidence interval [CI]: 1.13-5.15) and less maternal morbidity (OR: 0.28; 95% CI: 0.14-0.55). Maternal morbidity of OVD is driven by perineal injury. Conclusion In laboring women with a previous uterine scar, attempting OVD is associated with greater maternal and less neonatal morbidity than LRCD.

To identify risk factors for infection following cesarean delivery (CD) and to investigate the effect of intervention on modifiable risk factors (MRF). A prospective, two-period cohort intervention study. All CD performed between September 2006 and August 2007 (era 1) and between July 2009 and June 2010 (era 2) were included. Infection control program was implemented before era 2 and included a refresher course in aseptic and scrub techniques to all surgical teams. Infectious morbidity was recognized up to 30 days from the operation. Risk factors were identified by multiple logistic regressions. A total of 1616 women included and analyzed during both eras. Logistic regression revealed that residency (rural as compared to urban), obesity and urgency of the CD were significant risk factors for infection. Prior to intervention, senior obstetricians had a lower infection rate than senior gynecologists (p = 0.02). Within both groups, the incidence in era 2 decreased and was comparable (obstetricians: 5.7 vs. 1.6%; p = 0.005; gynecologists: 12.7 vs. 1.1%; p = 0.003). Among the group of scrub nurses who took part in less than 20 CD during era 1, the intervention reduced significantly the infection rate during era 2 (p = 0.0002). Surgical team is a MRF for infection following CD. Intervention decreased this unintended clinical effect attributed to surgical teams.

To observe the incidence of, indications for, and complications associated with second-stage cesarean delivery in 10-year intervals over 30 years. The present analysis of prospectively collected data compared cesarean deliveries during 1976, 1986, 1996, and 2006 at John Radcliffe Hospital in Oxford, UK (n=3222). Pregnancy, delivery, and neonatal details were reviewed. The proportion of deliveries by cesarean in the second stage of labor increased from 0.5% (22/4464) in 1976 to 2.1% (124/5998) in 2006 (Pcesarean deliveries during the second stage because of failed instrumental delivery also increased over the study period from 59.1% (13/22) in 1976 to 71.0% (88/124) in 2006. Compared with cesareans at other stages, uterine trauma (Pcesarean delivery. Neonates delivered by second-stage cesarean had lower Apgar scores (Pcesarean earlier in labor. A trend towards an increase in neonatal trauma with second-stage cesarean compared with cesarean delivery before labor or during the first stage did not reach statistical significance. The proportion of deliveries by cesarean in the second stage of labor increased; these deliveries were associated with greater maternal and neonatal morbidity, but were not influenced by the indication for cesarean. © 2017 International Federation of Gynecology and Obstetrics.

BACKGROUND: There has always been an asking question with physicians and health staff whether delivery mode can effect on child intelligence. This study was conducted to compare the intelligence quotient (IQ) of school aged children delivered by cesarean section and vaginal delivery in Mashhad, Iran. METHODS: This study conducted in two stages; a cross-sectional section in which 5000 randomly selected children, who were 6-7 years old, attended at 10 Cognitive Examination Posts in Mashhad. The examination was performed by the Exceptional Education and Training Institute affiliated to Ministry of Education for all 6-7 years old children at the entry to the primary school. At the second stage, we selected two matched groups of 189 children who delivered by cesarean section or spontaneous vaginal delivery and then compared their IQ scores. RESULTS: The cesarean delivery group had significantly higher IQ test scores. Maternal and paternal educational levels were related to children’s IQ scores. After adjusting of maternal and paternal education, maternal age and parity, there was not any significant difference between IQ scores of cesarean delivery and natural vaginal delivery groups 101(3.67) vs. 100.7(4.28). CONCLUSIONS: Based on our findings, the association between cesarean deliveries with better cognitive development in children cannot be supported. PMID:21589777

Background Laborist practice models are associated with lower cesarean delivery rates than individual private practice models in several studies; however, this effect is not uniform. Further exploration of laborist models may help us better understand the observed reduction in cesarean delivery rates in some hospitals with implementation of a laborist model. Objective Our objective was to evaluate the degree of variation in primary cesarean delivery rates by individual laborists within a single institution employing a laborist model. In addition, we sought to evaluate whether differences in cesarean delivery rates resulted in different maternal or short-term neonatal outcomes. Study Design At this teaching institution, one laborist (either a generalist or maternal-fetal medicine attending physician) is directly responsible for labor and delivery management during each shift. No patients are followed in a private practice model nor are physicians incentivized to perform deliveries. We retrospectively identified all laborists who delivered nulliparous, term women with cephalic singletons at this institution from 2007-14. Overall and individual primary cesarean delivery rates were reported as percentages with exact Pearson 95% CI. Laborists were grouped by tertile as having low, medium or high cesarean delivery rates. Characteristics of the women delivered, indications for cesarean delivery, and short-term neonatal outcomes were compared between these groups. A binomial regression model of cesarean delivery was estimated, where the relative rates of each laborist compared to the lowest-unadjusted laborist rate were calculated; a second model was estimated to adjust for patient-level maternal characteristics. Results Twenty laborists delivered 2,224 nulliparous, term women with cephalic singletons. The overall cesarean delivery rate was 24.1% (95% CI 21.4-26.8). In an unadjusted binomial model, the overall effect of individual laborist was significant (pcesarean

Preterm delivery represents a substantial problem in perinatal medicine worldwide. Current knowledge on potential influences of probiotics in food on pregnancy complications caused by microbes is limited. We hypothesized that intake of food with probiotics might reduce pregnancy complications caused by pathogenic microorganisms and, through this, reduce the risk of spontaneous preterm delivery. This study was performed in the Norwegian Mother and Child Cohort on the basis of answers to a food-frequency questionnaire. We studied intake of milk-based products containing probiotic lactobacilli and spontaneous preterm delivery by using a prospective cohort study design (n = 950 cases and 17,938 controls) for the pregnancy outcome of spontaneous preterm delivery (delivery were associated with any intake of milk-based probiotic products in an adjusted model [odds ratio (OR): 0.857; 95% CI: 0.741, 0.992]. By categorizing intake into none, low, and high intakes of the milk-based probiotic products, a significant association was observed for high intake (OR: 0.820; 95% CI: 0.681, 0.986). Women who reported habitual intake of probiotic dairy products had a reduced risk of spontaneous preterm delivery.
A case-control study of twins was performed to identify clinical predictions of emergency cesarean delivery in the second-born twin after vaginal delivery of the first twin. The obstetric records were reviewed of all twin vaginal deliveries at the Japanese Red Cross Katsushika Maternity Hospital from 2002 through 2007. There were 206 vaginal deliveries of first twins at >or=33 weeks of gestation. Of these deliveries, nine women (4.4%) underwent an emergency cesarean for the delivery of the second twin. The incidence of cesarean delivery for the second twin was significantly greater in cases with a history of infertility therapy (odds ratio: 5.0, 95% confidence intervals: 1.2-22), gestational age at >or=39 weeks (24, 4.7-120), nonvertex presentation (6.2, 1.5-26), operative delivery of the first twin (6.1, 1.5-24) and intertwin delivery time interval >30 min (7.2, 1.7-30). The most important risk factor of emergency cesarean delivery in the second twin was a gestational age of >or=39 weeks.

Cesarean section is the commonest obstetric operative procedure worldwide. When used appropriately cesarean sections can improve infant and/or maternal outcomes. However, when used inappropriately the potential harm may exceed the potential benefit of cesarean section. Appreciating the limited information in this area the current study assessed the rate and factors associated with cesarean section in Felegehiwot referral hospital, Bahir Dar, northwest Ethiopia. The study was a retrospective analysis of eligible patient records that included 2967 pregnant women who had underwent either cesarean or vaginal delivery from July 1, 2012 to June 31, 2013. The data were double entered to EPI-INFO 3.5.2 and analyzed with SPSS. Binary logistic regression model was fitted to identify independent factors associated with cesarean section. The proportion of women who underwent cesarean section in this study was 25.4%. Obstructed labor (30.7%), fetal distress (15.9%) and abnormal presentation (13.4%) were the major obstetric indications for cesarean section. The odd of undergoing cesarean section was higher among mothers in rural residence (AOR = 1.63, 95% CI: 1.21, 2.20), mothers reported to have pregnancy risk factors (AOR = 2.31, 95% CI: 1.74, 3.07) and lower among mothers in age category of 15-19 (AOR = 0.63, 95% CI: 0.43, 0.93). Obstetric factors occurring around birth, including obstructed labor and fetal distress were the main reasons leading to Cesarean Section rather than background characteristics assumed to be a risk. The results imply that there is a need for timely and accurate screening of women during obstetric care and, decision to perform cesarean section should be based on clear, compelling and well-supported justifications.

We compared the short-term maternal and neonatal outcomes of women who deliver by cesarean without labor compared with women who deliver by cesarean after labor or by vaginal birth. This was a retrospective cohort study of women delivering a first baby from 1998 to 2002. Hospital discharge diagnostic coding identified unlabored cesarean deliveries (UCDs), labored cesarean deliveries (LCDs), and vaginal births (VBs). Medical records were abstracted and mode of delivery confirmed. The three outcomes of interest were maternal bleeding complications, maternal febrile morbidity, and neonatal respiratory complications. Using logistic regression for each outcome, we investigated whether mode of delivery was associated with the outcome, independent of other factors. The study groups included 513 UCDs, 261 LCDs, and 251 VBs. Compared with the UCD group, the adjusted odds of bleeding complications was higher in the LCD comparison group (odds ratio [OR] 2.3; 95% confidence interval [CI] 1.21, 4.53) and the VB comparison group (OR 1.96; 95% CI 0.95, 4.02). The incidence of febrile morbidity was similar for both cesarean groups but lower in the VB group. Both comparison groups had lower odds of neonatal complications than the UCD group (OR for LCD comparison group 0.52; 95% CI 0.27, 0.95 and OR for VB comparison group 0.26; 95% CI 0.098, 0.59). Scheduled cesarean is associated with increased odds of neonatal respiratory complications but decreased odds of maternal bleeding complications. PMID:19021093
Full Text Available Objective. To compare the infectious complication rates from cesarean delivery of human immunodeficiency virus (HIV-infected women and HIV-negative women. Materials and Methods. A retrospective analysis was performed on data derived from HIV-infected women and HIV-negative women, who underwent cesarean delivery at two teaching hospitals. Main outcome measures were infectious postoperative morbidity. Descriptive, comparison analysis, and multiple logistic regression analysis were performed. Results. One hundred and nineteen HIV-infected women and 264 HIV-negative women delivered by cesarean section and were compared. The HIV-negative women were more likely than the HIV-infected women to deliver by emergent cesarean section (78.0% versus 51.3%, resp., .05. In a multivariate stepwise logistic analysis, emergent cesarean delivery and chorioamnionitis but not HIV infection were associated with increased rate of post-operative endometritis (odds ratio (OR 4.10, 95% confidence interval (95% CI 1.41–11.91, <.01, and OR 3.02, 95% CI 1.13–8.03, <.05, resp.. Conclusion. In our facilities, emergent cesarean delivery and chorioamnionitis but not HIV infection were identified as risk factors for post-operative endometritis.

To investigate the cost-effectiveness of adding azithromycin to standard cephalosporin regimens of cesarean delivery prophylaxis by considering the maternal outcomes in the current and potential subsequent pregnancies. A cost-effectiveness model was created using TreeAge to compare the outcomes of using azithromycin-cephalosporin with cephalosporin alone in a theoretical cohort of 700,000 women, the approximate number of nonelective cesarean deliveries annually in the United States that occur during labor or after membrane rupture. Outcomes examined included endometritis, wound infection, sepsis, venous thromboembolism, and maternal death in the current pregnancy and uterine rupture, cesarean hysterectomy, and maternal death in subsequent pregnancies, including cost and quality-adjusted life-years for both pregnancies. Probabilities, utilities, and costs were derived from the literature, and a cost-effectiveness threshold was set at $100,000 per quality-adjusted life-year. Sensitivity analyses were used to determine the robustness of our results. Compared with cephalosporin alone for prophylaxis, our model showed 16,100 fewer cases of endometritis, 17 fewer cases of sepsis, eight fewer cases of venous thromboembolism, and one fewer maternal death with azithromycin-cephalosporin. Additionally, this strategy prevented 36 uterine ruptures and four cesarean hysterectomies in the subsequent pregnancy. Overall, the addition of azithromycin led to both lower costs and higher quality-adjusted life-years when compared with standard cephalosporin prophylaxis. In sensitivity analysis, we found that as long as the cost of azithromycin remained below $930 (baseline cost $27), it was cost-effective. For women who undergo cesarean delivery in labor or after membrane rupture, compared with cephalosporin alone, the addition of azithromycin to cesarean delivery infection prophylaxis is less costly and leads to better maternal outcomes in the index delivery and subsequent deliveries

To compare rates of complications associated with cesarean delivery in HIV-infected and HIV-uninfected women in the United States and to investigate trends in such complications across four study cycles spanning the implementation of HAART in the United States (1995-1996, 2000-2001, 2005-2006, 2010-2011). The Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project is the largest all-payer hospital inpatient care database in the United States; when weighted to account for the complex sampling design, nationally representative estimates are derived. After restricting the study sample to women aged 15-49 years, our study sample consisted of approximately 1 090 000 cesarean delivery hospitalizations annually. Complications associated with cesarean deliveries were categorized as infection, hemorrhage, or surgical trauma, based on groups of specific International Classification of Diseases 9th revision codes. Length of hospitalization, hospital charges, and in-hospital deaths were also examined. The rate of complications significantly decreased during the study periods for HIV-infected and HIV-uninfected women. However, rates of infectious complications and surgical trauma associated with cesarean deliveries remained higher among HIV-infected, compared with HIV-uninfected women in 2010-2011, as did prolonged hospital stay and in-hospital deaths. Length of hospitalization decreased over time for cesarean deliveries of HIV-infected women to a greater extent compared with HIV-uninfected women. In the United States, rates of cesarean delivery complications decreased from 1995 to 2011. However, rates of infection, surgical trauma, hospital deaths, and prolonged hospitalization are still higher among HIV-infected women. Clinicians should remain alert to this persistently increased risk of cesarean delivery complications among HIV-infected women.

To compare the mortality, morbidity of emergency and elective cesarean section with vaginal delivery among Asian teaching hospitals. Hospital based prospective study at 12 centers of 9 countries. 12 591 vaginal deliveries, 3062 elective and 4328 emergency cesarean section were followed up to 5 days postpartum. Maternal deaths (95% CI) per 1000 births among vaginal deliveries being 0.47 (0.17, 1.03) was not significantly different from 0.31 (0.01, 1.73) of elective cesarean section and both rates were significantly lower than 2.87 (1.53, 4.91) per 1000 births of emergency section. The vaginal delivery group had significantly lower incidences of all major complication except significantly higher chance of secondary operations and non-significantly different risk for endometritis. Corresponding neonatal mortality per 1000 deliveries among the three groups were 7 (5.6, 8.6), 2.2 (0.9, 4.6) and 12.4 (9.3, 16.2) (P cesarean section. Maternal complications were increased by cesarean delivery but elective section may reduce neonatal complication.

To compare the clinical, laboratory, and demographic variables of women in our clinic with systemic lupus erythematosus (SLE) who have had a pregnancy resulting in a live birth and identify any correlations with either term or preterm delivery. Pregnancies in women with SLE from 1999 to 2001 were retrospectively reviewed. We recorded demographic data, disease activity (SLE Disease Activity Index, SLEDAI), obstetric history, prednisone dosage, other medications taken during pregnancy, history of renal disease, and autoantibody status [including antinuclear antibody, anti-DNA, anticardiolipin IgG (aCL), and lupus anticoagulant (LAC)]. Preterm delivery was defined as gestational age at delivery pregnancy, and outcome. Of the 72 pregnancies, 28 (38.9%) resulted in preterm deliveries. There were no significant differences in any demographic or disease variables measured comparing term versus preterm delivery groups. More women in the preterm group were taking > or = 10 mg/day prednisone during their pregnancy (50.0% vs 22.2%; p = 0.028), and the mean dose was significantly higher than the term group taking > or = 10 mg/day (24.8 vs 16.7 mg/day; p = 0.047). There was a higher prevalence of women with aCL IgG in the preterm group (p = 0.023). The mean weeks gestation was shorter for women positive for aCL IgG compared to the group negative for aCL (34.9 +/- 4.4 vs 37.5 +/- 3.2 weeks, respectively; p = 0.032). There was no difference in second trimester disease activity between the term and preterm groups (33.3% and 36.4% of each group had a SLEDAI of 0). However, significantly more women in the term group received no medication during their pregnancies compared to women in the preterm group (20.0% vs 0.0%; p = 0.031). The rates of preterm deliveries, premature rupture of membranes, intrauterine growth restriction, and aPL in SLE pregnancies vary considerably in published reports, most of which are retrospective analyses. Our rates closely approximate the median values for

The rate of cesarean delivery is increasing in North America. Surgical site infection following this operation can make it difficult to recover, care for a baby and return home. We aimed to determine the incidence of surgical site infection to 30 days following cesarean delivery, associated risk factors and whether risk factors differed for predischarge versus postdischarge infection. We identified a retrospective cohort in Nova Scotia by linking the provincial perinatal database to hospital admissions and physician billings databases to follow women for 30 days after they had given birth by cesarean delivery between Jan. 1, 1997 and Dec. 31, 2012. Logistic regression with generalized estimating equations was used to determine risk factors for infection. A total of 25 123 women had 33 991 cesarean deliveries over the study period. Of the 25 123, 923 had surgical site infections, giving an incidence rate of 2.7% (95% CI 2.54%-2.89%); the incidence decreased over time. Risk factors for infection (adjusted odds ratios ≥ 1.5) were prepregnancy weight 87.0 kg or more, gaining 30.0 kg or more during pregnancy, chorioamnionitis, maternal blood transfusion, anticoagulation therapy, alcohol or drug abuse, second stage of labour before surgery, delivery in 1997-2000 and delivery in a hospital performing 130-1249 cesarean deliveries annually. Women who gave birth earlier in the study period, those who gave birth in a hospital with 130-949 cesarean deliveries per year and those with more than 1 fetus were at a significantly higher risk for surgical site infection before discharge; women who smoked were at significantly higher risk for surgical site infection after discharge. Most risk factors are known before delivery, and some are potentially modifiable. Although the incidence of surgical site infection decreased over time, targeted clinical and infection prevention and control interventions could further reduce the burden of illness associated with this health

This experimental study was conducted to determine the level of anxiety in women undergoing multiple cesarean section. Sixty multiple cesarean section referrals were randomly assigned to either the experimental or control groups. Data was collected at the Karaman Public Health Hospital in Turkey, from June 2015 to June 2016. Songs chosen earlier by the patients were played during the cesarean section procedure for the experimental group. The control group was studied without music. Data was collected using a questionnaire form, and Visual Analogue Scale (VAS) was used to determine the anxiety levels. The t-test and chi-square test were used to analyse statistically significant differences between the groups. The VAS scores before and during the procedure showed significantly lower scores for the experimental group, compared to the control group (p<0.05). Music therapy reduces the physiological and cognitive responses of anxiety in patients undergoing multiple cesarean section, and can be used in the clinical practice.

International rates of operative delivery are consistently higher than the World Health Organization determined is appropriate. This suggests that factors other than clinical indications contribute to cesarean section. Data presented here are from interviews with 115 mothers on the postnatal ward of a hospital in Northeast England during February 2006 to March 2009 after the women underwent either unscheduled or scheduled cesarean childbirth. Using thematic content analysis, we found women’s ...

Maternal S-cortisol levels increase throughout pregnancy and peak in the third trimester. Even higher levels are seen during the physical stress of delivery. Since analgesia for women in labor has improved, it is possible that maternal stress during labor is reduced. The aim of this study was to compare maternal S-cortisol during vaginal delivery and elective cesarean section. Twenty healthy women with spontaneous vaginal delivery and healthy women (n = 20) undergoing elective cesarean section were included in the study. S-cortisol was measured during three stages of spontaneous vaginal delivery (tvd1, tvd2 and tvd3), as well as before and after elective cesarean section (tcs1 and tcs2). In the vaginal delivery group, mean S-cortisol at tvd1 was 1325 ± 521 nmol/L, at tvd2 1559 ± 591 nmol/L and at tvd3 1368 ± 479 nmol/L. In the cesarean section group, mean S-cortisol at tcs1 was 906 ± 243 nmol/L and at tcs2 831 ± 257 nmol/L. S-cortisol was higher in the vaginal delivery group at the onset of labor as compared to the cesarean section preoperative group (p = 0.006). There were also significant differences between S-cortisol levels postpartum as compared to postoperatively (p cesarean section, indicating higher stress levels. A reduction in the hydrocortisone dose at childbirth in women with adrenal insufficiency should be considered, particularly in women undergoing an elective cesarean section.
exact etiology is still unclear, however, associated risk factors include maternal hypertension, advanced maternal age, polyhydramnios, multiparity, abdominal trauma, intrauterine growth restriction, intrauterine infection, premature rupture of membranes, threatened miscarriage, and cocaine abuse.. According to Sher and ...

To assess the maternal and neonatal consequences of scheduling elective repeated cesarean section (ERCS) at 39 weeks rather than 38 weeks and to assess the impacts of delivering by emergency cesarean section (CS) before the planned date. Retrospective Cohort study. Patients with previous two or more CS planned for ERCS at term during the period from January to June 2011. Medical records were reviewed for demographic and clinical data, planned timing of CS, emergency cesarean and any adverse maternal or neonatal outcome. Adverse maternal or neonatal outcome. Four hundred and twenty women were included, 71.4% of cases were posted <39 weeks and 28.6% were posted at ≥39 weeks. Patients posted ≥ 39 weeks were more prone to deliver by emergency CS (16.6 vs. 10.6%) and the neonates were less prone to RDS and NICU admission (p < 0.05). Our data support the justification to book patients for ERCS at ≥39 weeks.

The optimal route for delivery of preterm breech-presenting fetuses remains a clinical dilemma. Available data from the literature are largely based on retrospective cohort studies, and randomised controlled trials are considered impossible to conduct. Consistently however, large population-based surveys have shown that planned caesarean sections for these fetuses were associated with better neonatal outcomes compared with those following vaginal delivery. Nevertheless, the increased surgical risks for the mother having caesarean delivery of an early preterm breech fetus must be balanced with the probable neonatal survival benefits. Planned caesarean section should probably be limited to gestations with at least a fair chance of independent neonatal survival, where vaginal delivery is not imminent, and in the absence of other maternal risk factors. Vaginal delivery would probably include those fetuses that are of marginal viability, and that additional protection from abdominal delivery was unlikely to be beneficial to neonatal outcome.

The objective of this study was to assess the frequency of urinary tract infection (UTI) with urine samples obtained via catheterization among women undergoing cesarean delivery at term pregnancy. A cross-sectional study involving 159 women in whom cesarean delivery was conducted at term pregnancy after a regular follow-up from first to third trimester. For screening and diagnosis of UTI during antenatal period, the authors used dipstick test and microscopic urinalysis, and urine culture was used in the presence of symptomatic UTI unresponsive to initial antibiotic therapy. A urine sample was obtained immediately after insertion of Foley catheter for urine dipstick test, microscopic urinalysis, and culture during cesarean delivery. Obstetric and UTI data were recorded. Of 159 pregnant women, 95 (59.8%) did not develop UTI during antenatal care. There was no patient with symptomatic UTI at the admission for cesarean delivery. The authors found UTI with urine dipstick and microscopic urinalysis in 12 patients and of them, four patients had no history of UTI, and all the remaining eight patients had asymptomatic UTI during antenatal follow-up. UTI according to urine culture was encountered in three patients, two of them had one episode of UTI, and one had two episodes of UTI during antenatal follow-up. After regular antenatal follow-up screening with urine dipstick, microscopic urinalysis, and counseling of pregnant women regarding UTIs, the frequency of bacteriuria decreases considerably during cesarean delivery.

To identify factors associated with cesarean delivery among women with class III obesity attempting vaginal delivery. In a retrospective study, medical charts were reviewed for women aged 18 years or older with a singleton pregnancy of at least 37 weeks and a body mass index (calculated as weight in kilograms divided by the square of height in meters) of 40 or higher who were eligible to attempt vaginal delivery at a maternity hospital in Lille, France, between 1999 and 2012. Among 345 eligible women, 301 (87.2%) attempted vaginal delivery; 211 (70.1%) were successful and 90 (29.9%) delivered by cesarean. The frequency of nulliparity was higher among those undergoing cesarean after a trial of labor (64 [71.1%]) than among those who delivered vaginally (57 [27.0%]; Pcesarean (61 [67.8%] vs 96 [45.5%]; Pcesarean among women attempting vaginal delivery (odds ratio [OR] 2.30, 95% confidence interval [CI] 1.25-4.22), whereas history of vaginal delivery was protective (OR 0.08, 95% CI 0.04-0.17). Nulliparous women with class III obesity attempting a vaginal delivery should be warned of the high risk of cesarean delivery, especially if they require induction. © 2016 International Federation of Gynecology and Obstetrics.

We evaluated the association between alcohol intake during pregnancy and preterm delivery. Women attending routine antenatal care at Aarhus University Hospital, Denmark, from 1989–1991 and 1992–1996 were eligible. We included 18,228 singleton pregnancies in the analyses. We obtained prospective...... information on alcohol intake at 16 and 30 weeks of gestation, other lifestyle factors, maternal characteristics, and obstetrical risk factors from self-administered questionnaires and hospital files. For women with alcohol intake of 1–2, 3–4, 5–9, and >=10 drinks/week the risk ratio (RR) of preterm delivery.......78–7.13) at 30 weeks. Adjustment for smoking habits, caffeine intake, age, height, pre-pregnant weight, marital status, occupational status, education, parity, chronic diseases, previous preterm delivery, mode of initiation of labor, and sex of the child did not change the conclusions, nor did restriction...
Full Text Available There has been some improvement in the treatment of preterm infants, which has helped to increase their chance of survival. However, the rate of premature births is still globally increasing. As a result, this group of infants are most at risk of developing severe medical conditions that can affect the respiratory, gastrointestinal, immune, central nervous, auditory and visual systems. In extreme cases, this can also lead to long-term conditions, such as cerebral palsy, mental retardation, learning difficulties, including poor health and growth. In the US alone, the societal and economic cost of preterm births, in 2005, was estimated to be $26.2 billion, per annum. In the UK, this value was close to £2.95 billion, in 2009. Many believe that a better understanding of why preterm births occur, and a strategic focus on prevention, will help to improve the health of children and reduce healthcare costs. At present, most methods of preterm birth prediction are subjective. However, a strong body of evidence suggests the analysis of uterine electrical signals (Electrohysterography, could provide a viable way of diagnosing true labour and predict preterm deliveries. Most Electrohysterography studies focus on true labour detection during the final seven days, before labour. The challenge is to utilise Electrohysterography techniques to predict preterm delivery earlier in the pregnancy. This paper explores this idea further and presents a supervised machine learning approach that classifies term and preterm records, using an open source dataset containing 300 records (38 preterm and 262 term. The synthetic minority oversampling technique is used to oversample the minority preterm class, and cross validation techniques, are used to evaluate the dataset against other similar studies. Our approach shows an improvement on existing studies with 96% sensitivity, 90% specificity, and a 95% area under the curve value with 8% global error using the polynomial

The objective of the study was to measure the copeptin levels in maternal serum and umbilical cord serum at cesarean section and vaginal delivery in normotensive pregnancy and pre-eclamptic women. This was a prospective study at Mansoura University Hospital, Egypt. Ninety cases were included. They were divided into six groups: (1) normal pregnancy near term, as a control group, (2) primiparas who had vaginal delivery, (3) primiparas who had vaginal delivery and mild preeclampsia, (4) elective repeat cesarean section, (5) intrapartum cesarean section for indications other than fetal distress, and (6) intrapartum cesarean section for fetal distress. Serum copeptin concentrations were quantified with an enzyme-linked immunosorbent assay (ELISA). Mean, standard deviation, and paired t-test were used to test for significant change in quantitative data. The vaginal delivery groups had higher levels of maternal serum copeptin than the elective cesarean section group (P<0.01). Higher maternal serum copeptin levels were found in cases with pre-eclampsia as compared with the normotensive cases. The maternal copeptin levels during intrapartum cesarean section were higher than that during elective repeat cesarean section. There was a significant correlation between maternal copeptin levels and the duration of the first stage. In the presence of fetal distress, umbilical cord serum copeptin levels were significantly higher than other groups. Vaginal delivery can be very painful and stressful, and is accompanied by a marked increase of maternal serum copeptin. Increased maternal levels of serum copeptin were found in cases with pre-eclampsia as compared with the normotensive cases, and it may be helpful in assessing the disease. Intrauterine fetal distress is a strong stimulus to the release of copeptin into the fetal circulation. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

We describe obstetric outcomes in a group of patients with prior cesarean delivery (CD) presenting with an intrauterine fetal demise (IUFD). A secondary analysis of an observational study of women with prior CD was performed. All antepartum singleton pregnancies with a prior CD and IUFD ≥20 weeks' gestation or 500 g were evaluated. Two hundred nine patients met inclusion criteria for analysis. The mean gestational age ± standard deviation at delivery was 31.3 ± 6.5 weeks. The trial of labor rate was 75.6% (158/209), and the vaginal birth after cesarean (VBAC) success rate was 86.7%. Labor induction or augmentation occurred in 83.3% of attempted VBAC. Uterine rupture occurred in five women (2.4%), and in 3.4% of those being induced but none of these required hysterectomy. Women with a history of previous CD and an IUFD often undergo trial of labor with a high VBAC success rate. Uterine rupture complicates 2.4% of such cases. © Thieme Medical Publishers.

Importance Planned cesarean delivery comprises a significant proportion of births globally, with combined rates of planned and unscheduled cesarean delivery in a number of regions approaching 50%. Observational studies have shown that offspring born by cesarean delivery are at increased risk of ill health in childhood, but these studies have been unable to adjust for some key confounding variables. Additionally, risk of death beyond the neonatal period has not yet been reported for offspring born by planned cesarean delivery. Objective To investigate the relationship between planned cesarean delivery and offspring health problems or death in childhood. Design, Setting, and Participants Population-based data-linkage study of 321 287 term singleton first-born offspring born in Scotland, United Kingdom, between 1993 and 2007, with follow-up until February 2015. Exposures Offspring born by planned cesarean delivery in a first pregnancy were compared with offspring born by unscheduled cesarean delivery and with offspring delivered vaginally. Main Outcomes and Measures The primary outcome was asthma requiring hospital admission; secondary outcomes were salbutamol inhaler prescription at age 5 years, obesity at age 5 years, inflammatory bowel disease, type 1 diabetes, cancer, and death. Results Compared with offspring born by unscheduled cesarean delivery (n = 56 015 [17.4%]), those born by planned cesarean delivery (12 355 [3.8%]) were at no significantly different risk of asthma requiring hospital admission, salbutamol inhaler prescription at age 5 years, obesity at age 5 years, inflammatory bowel disease, cancer, or death but were at increased risk of type 1 diabetes (0.66% vs 0.44%; difference, 0.22% [95% CI, 0.13%-0.31%]; adjusted hazard ratio [HR], 1.35 [95% CI, 1.05-1.75]). In comparison with children born vaginally (n = 252 917 [78.7%]), offspring born by planned cesarean delivery were at increased risk of asthma requiring hospital admission (3.73% vs 3

Full Text Available Background & aim: Postpartum period is accompanied by significant changes in women’s quality of life. These alterations can affect the health of mothers and children. Considering the importance of postnatal quality of life and its different contributing factors, this study aimed to compare women’s quality of life after vaginal delivery and cesarean section. Methods:This retrospective cohort study included a random sample of 2100 women, referring to Hamadan health care centers for congenital hypothyroidism screening or infant vaccination. The participants’ quality of life was examined, using Short Form-36 (SF-36 questionnaire, evaluating five periods of time including one week, two months, four months, six months, and one year after delivery (either vaginal or cesarean delivery. Data were analyzed using t-test. Results: Quality of life was significantly higher in women with vaginal delivery, compared to women with cesarean section in all periods including one week (68.77 vs. 42.44, two months (69.11 vs. 54.76, four months (78.19 vs. 53.02, six months (75.62 vs. 54.94,and one year(78.43 vs. 53.77 after delivery. Conclusion: Considering women’s higher quality of life after vaginal delivery, compared to cesarean section, it seems that vaginal delivery is a safer and less expensive option, which is recommended for all pregnant women.

To discover the differences between women with gestational diabetes mellitus (GDM) who delivered vaginally and those who delivered by cesarean section, and to assess the cesarean rate in this group of women. We divided all pregnant women with GDM into 2 groups: those who had vaginal delivery and those who gave birth by cesarean section (retrospective study of 6 years). We evaluated 460 births at term (≥ 37 weeks' gestation), for a total of 240 vaginal births and 220 cesarean births. All occurred in our institution. Of all the variables that were compared between the 2 groups, we found statistically significant differences (p history of macrosomia and gestational age at the time of beginning insulin treatment. Pregnant women with GDM and previous history of macrosomia are more likely to be submitted to cesarean section. Also, the initiation of insulin treatment at an early gestational age is associated with a higher chance of a woman delivering by cesarean section. The cesarean section rate in women with GDM was 47.8%.

Preterm delivery is the leading cause of neonatal morbidity and mortality. Two-thirds of preterm deliveries are idiopathic. The initiating molecular mechanisms behind spontaneous preterm delivery are unclear. Umbilical cord blood DNA samples are an easy source of material to study the neonatal state
The influence of the type of institutional setting on cesarean delivery is well documented. However, the traditional boundaries between public and private providers have become increasingly blurred with the commercialization of the state health sector that allows providers to tailor the quantity and quality of care according to patients' ability to pay. This study examined wealth-related variations in cesarean rates in six lower- and upper-middle income countries: the Dominican Republic, Egypt, Guatemala, Jordan, Pakistan, and the Philippines. Demographic and Health Survey data and a hierarchical regression model were used to assess wealth-related variations in cesarean rates in government and private hospitals while controlling for a wide range of women's socioeconomic and risk profiles. The odds of undergoing a cesarean delivery were greater in private facilities than government hospitals by 58% in Jordan, 129% in Guatemala, and 262% and 279% in the Dominican Republic and Egypt, respectively. Additional analysis involving interactions between the type of facility and wealth quintiles indicated that wealthier women were more likely to undergo a cesarean birth in government hospitals than poorer women in all countries but the Dominican Republic and Guatemala. Moreover, in both Egypt and Jordan, differences in cesarean rates between government and private hospitals were smaller for the wealthier strata than for the nonwealthy. Large wealth-related variations in the mode of delivery across government and private hospitals suggest the need for well-developed guidelines and standards to achieve a more appropriate selection of cases for cesarean delivery. © 2018 Wiley Periodicals, Inc.

Background The optimal mode of delivery in twin pregnancies remains controversial. A recent randomized trial did not find any benefit of planned cesarean vs. vaginal delivery at 32–38 weeks gestation, but the trial was not powered to detect a moderate effect. We aimed to evaluate the impact of cesarean delivery on perinatal mortality and severe neonatal morbidity in twin pregnancies at ≥32 weeks through a large database exploration approach with the power to detect moderate risk differences. Methods In a retrospective birth cohort study using the U.S. matched multiple births, 1995–2000 (the available largest multiple birth dataset), we compared perinatal outcomes in twins (n = 181,810 pregnancies) delivered at 32–41 weeks gestation without congenital anomalies. The primary outcome was a composite of perinatal death and severe neonatal morbidity. Cox regression was used to estimate the adjusted hazard ratio (aHR) controlling for the propensity to cesarean delivery, fetal characteristics (sex, birth weight, birth weight discordance, same-sex twin or not) and twin-cluster level dependence. Prospective risks were calculated using the fetuses-at-risk denominators. Results The overall rates of the primary outcome were slightly lower in intended cesarean (6.20%) vs. vaginal (6.45%) deliveries. The aHRs of the primary outcome were in favor of vaginal delivery at 32 (aHR = 1.06, p = 0.03) or 33 (aHR = 1.22, pcesarean delivery at 36 (aHR = 0.94, p = 0.004), 37, 38 and 39+ weeks (aHR: 0.72 to 0.78, all pcesarean vs. vaginal deliveries at 36+ weeks of gestation remained when the analyses were restricted to different-sex (dichorionic) twins (aHR = 0.84, 95% CI 0.80–0.88). Conclusion Cesarean delivery may be beneficial for perinatal outcomes overall in twin pregnancies at ≥36 weeks gestation. PMID:27227678

To investigate the association between previous cesarean delivery and medication abortion failure and the association between parity and failure. Data were abstracted from 2035 consecutive charts of women who underwent medication abortion in 2011. All women were at 63 days gestation or less and received mifepristone 200mg orally and misoprostol 800 mcg buccally. We used multivariate logistic regression to assess the relationship between failure, defined as requiring either curettage or additional medication, and prior cesarean delivery. We also examined the relationship between failure and parity. Follow-up was available on 1609 (79%) patients. Overall, 4.5% of patients experienced failure. Neither cesarean delivery nor parity was associated with failure; 6.5% of women with prior cesarean delivery experienced failure, compared to 3.7% of nulliparous women [adjusted odds ratio (aOR), 1.79, 95% confidence interval (CI), 0.83-3.87]. With regard to parity, 4.7% of women with two or more previous births experienced failure, compared to 3.7% of nulliparous women (aOR, 1.07, 95% CI, 0.54-2.14). We did not find significant associations between prior cesarean delivery and failure or parity and failure. A previous study of patients who had received a less effective regimen reported significant associations between cesarean delivery and failure and parity and failure. While our results do not rule out the possibility of modest associations due to our limited statistical power, they are reassuring relative to previous findings. Our results suggest that if there are differences in women's odds of medication abortion failure by obstetric history, such differences are unlikely to be large. Providers and patients may factor this information into decision making about methods of pregnancy termination. Copyright © 2015 Elsevier Inc. All rights reserved.

Impetigo herpetiformis (IH), or generalized pustular psoriasis of pregnancy, is an exceedingly rare, generalized pustular skin eruption occurring during pregnancy associated with hypovolemia, sepsis, hypocalcemia, and airway edema. Fetal outcomes are generally poor, and parturients with IH may present with emergent indications for cesarean delivery due to placental insufficiency. We present a case of IH in a 19-year-old G1P0 who underwent successful general anesthesia for cesarean delivery. Her case highlights the anesthetic implications for patients afflicted with this rare disease, including perioperative pain management, airway concerns, considerations for neuraxial anesthesia, and monitoring challenges.

To assess the efficacy of vaginal cleansing before cesarean delivery in reducing postoperative endometritis. MEDLINE, Ovid, EMBASE, Scopus, Clinicaltrials.gov, and Cochrane Library were searched from their inception to January 2017. Selection criteria included all randomized controlled trials comparing vaginal cleansing (ie, intervention group) with a control group (ie, either placebo or no intervention) in women undergoing cesarean delivery. Any method of vaginal cleansing with any type of antiseptic solution was included. The primary outcome was the incidence of endometritis. Meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce summary treatment effects in terms of relative risk (RR) with 95% CI. Sixteen trials (4,837 women) on vaginal cleansing immediately before cesarean delivery were identified as relevant and included in the review. In most of the included studies, 10% povidone-iodine was used as an intervention. The most common way to perform the vaginal cleansing was the use of a sponge stick for approximately 30 seconds. Women who received vaginal cleansing before cesarean delivery had a significantly lower incidence of endometritis (4.5% compared with 8.8%; RR 0.52, 95% CI 0.37-0.72; 15 studies, 4,726 participants) and of postoperative fever (9.4% compared with 14.9%; RR 0.65, 95% CI 0.50-0.86; 11 studies, 4,098 participants) compared with the control group. In the planned subgroup analyses, the reduction in the incidence of endometritis with vaginal cleansing was limited to women in labor before cesarean delivery (8.1% compared with 13.8%; RR 0.52, 95% CI 0.28-0.97; four studies, 440 participants) or those with ruptured membranes (4.3% compared with 20.1%; RR 0.23, 95% CI 0.10-0.52; three studies, 272 participants). Vaginal cleansing immediately before cesarean delivery in women in labor and in women with ruptured membranes reduces the risk of postoperative endometritis. Because it is generally inexpensive and a

Obesity is a known risk factor for cesarean delivery. Limited data are available regarding the reasons for the increased rate of primary cesarean in obese women. It is important to identify the factors leading to an increased risk of cesarean to identify opportunities to reduce the primary cesarean rate. We evaluated indications for primary cesarean across body mass index (kg/m(2)) classes to identify the factors contributing to the increased rate of cesarean among obese women. In the Consortium of Safe Labor study from 2002 through 2008, we calculated indications for primary cesarean including failure to progress or cephalopelvic disproportion, nonreassuring fetal heart tracing, malpresentation, elective, hypertensive disease, multiple gestation, placenta previa or vasa previa, failed induction, HIV or active herpes simplex virus, history of uterine scar, fetal indication, placental abruption, chorioamnionitis, macrosomia, and failed operative delivery. For women with primary cesarean for failure to progress or cephalopelvic disproportion, dilation at the last recorded cervical examination was evaluated. Women were categorized according to body mass index on admission: normal weight (18.5-24.9), overweight (25.0-29.9), and obese classes I (30.0-34.9), II (35.0-39.9), and III (≥40). Cochran-Armitage trend test and χ(2) tests were performed. Of 66,502 nulliparous and 76,961 multiparous women in the study population, 19,431 nulliparous (29.2%) and 7329 multiparous (9.5%) women underwent primary cesarean. Regardless of parity, malpresentation, failure to progress or cephalopelvic disproportion, and nonreassuring fetal heart tracing were the common indications for primary cesarean. Regardless of parity, the rates of primary cesarean for failure to progress or cephalopelvic disproportion increased with increasing body mass index (normal weight, overweight, and classes I, II, and III obesity in nulliparous women: 33.2%, 41.6%, 46.4%, 47.4%, and 48.9% [P cesarean for

To investigate the severe adverse pregnancy outcomes in pregnancies with placenta previa and prior cesarean delivery and its risk factors. This retrospective casecontrol study reviewed all pregnancies with placenta previa and prior cesarean delivery delivered by repeat cesarean section in our institution between January 2005 and June 2015,and investigated the incidence of severe adverse pregnancy outcome. A composite of severe adverse pregnancy outcomes (including transfusion of 10 units or more red blood cells,maternal ICU admission,unanticipated injuries,repeat operation,hysterectomy,and maternal death) and other maternal and neonatal outcomes were described. Univariate and multivariable logistic regression analysis were used to quantify the effects of risk factors on severe adverse pregnancy outcomes. There were 478 women with placenta previa and prior cesarean delivery in our hospital over the last decade. The average age of them was 32.5±4.8 years old,most women were beyond 30 years old,the average gravidity and parity were 4 and 1,131 cases (27.4%) had severe adverse pregnancy outcomes. Transfusion of 10 units or more red blood cells happened in 75 cases (15.7%,75/478); 44 cases (9.2%,44/478) necessitated maternal ICU admission; unanticipated bladder injury occurred in 11 cases,but non ureter or bowel injury happened; All 4 repeat operations were due to delayed hemorrhage after conservative management during cesarean delivery,and an emergent hysterectomy was performed for all of the 4 cases. Hysterectomy (107 cases,22.4%) was the most common severe adverse pregnancy outcome. Among all 311 morbidly adherent placenta cases finally confirmed by pathological or surgical findings or both,only 172 (55.3%) were suspected before delivery. Multivariable logistic regression analysis showed that the risk of severe adverse pregnancy outcomes was significantly increased by pernicious placenta previa (i.e. anterior placenta overlying the prior cesarean scar),suspicion of

The circadian timing system has a rhythm and one of the roles of this system is the mediation of hormonal and metabolic adaptations to lactation. This study was conducted to determine whether the time to stage II lactogenesis differed in women who underwent cesarean section (CS) in the daytime (DT) or night-time (NT). This study was conducted at Süleymaniye Research and Education Hospital between June and December 2016. Two hundred and eighty-eight mothers who had a cesarean delivery and their healthy singleton neonates were included. Clinical and demographic data of the mothers and neonates, time of initiation of breastfeeding and time to stage II lactogenesis were analyzed according to DT or NT CS groups. There were no statistically significant differences in age, gravida, parity, body mass index, week of gestation at birth, postoperative hemoglobin level, cesarean indications, anesthesia type, previous history of breastfeeding, transfusion need, Apgar scores or birth weight-height of neonates between the DT and NT CS groups. While the time of initiation of breastfeeding did not differ statistically in terms of DT or NT CS groups, the time to stage II lactogenesis was significantly longer in the NT CS group. NT cesarean delivery is a risk factor for the delayed onset of lactogenesis. The results of this study may be useful to clinical practitioners counseling mothers who undergo NT cesarean delivery. © 2018 Japan Society of Obstetrics and Gynecology.

Previous studies of induction of labor in the setting of trial of labor after cesarean have compared women undergoing trial of labor after cesarean to those undergoing spontaneous labor. However, the clinically relevant comparison is to those undergoing expectant management. The objective of this study was to compare obstetric outcomes between women undergoing induction of labor and those undergoing expectant management ≥39 weeks of gestation. This was a secondary analysis of data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network Cesarean Registry that included women with singleton gestations at a gestational age of ≥39 weeks and a history of 1 low transverse cesarean delivery. Outcomes of induction at 39, 40, and 41 weeks were compared to expectant management beyond each gestational age period using univariable and multivariable analyses. Women with scheduled repeat cesarean deliveries done for the indication of prior cesarean delivery were excluded from the analysis. In all, 12,676 women were eligible for analysis. The rate of vaginal birth after cesarean (VBAC) was higher among women undergoing induction of labor at 39 weeks compared to expectant management (73.8% vs 61.3%, P < .001). The risk of uterine rupture also was higher among women undergoing induction of labor at 39 weeks compared to expectant management (1.4% vs 0.5%, P = .006, respectively). In multivariable analysis, induction of labor at 39 weeks remained associated with a significantly higher chance of VBAC and uterine rupture (odds ratio, 1.31; 95% confidence interval, 1.03-1.67; and odds ratio, 2.73; 95% confidence interval, 1.22-6.12, respectively). Induction of labor at 39 weeks, when compared to expectant management, was associated with a higher chance of VBAC but also of uterine rupture. Copyright © 2015 Elsevier Inc. All rights reserved.

We examine the association between prior C-section and subsequent pre-eclampsia; and describe the effect of gestational age at prior C-section, and obesity status on this association. The study population included women with two subsequent singleton births in Missouri between 1998 and 2005. The risk for pre-eclampsia/eclampsia was assessed among women with and without prior cesarean delivery. The two groups were followed to their second pregnancy and the occurrence of pre-eclampsia was documented. Additionally, the history of pre-eclampsia, prior cesarean at preterm, and obesity status were examined for their differential effects on the risk of pre-eclamsia. Women with prior C-section were 28% more likely to have pre-eclampsia in their subsequent pregnancy [OR = 1.28; 95% CI = 1.20-1.37]. However, this result was not significant when women with pre-eclampsia in their first pregnancy were excluded. After this exclusion, a more than threefold increased risk for subsequent pre-eclampsia was observed in women with prior early C-section [OR = 3.15; 95% CI= 2.43-4.08], while the level of risk did not change in the prior late C-section group [OR = 0.90; 95% CI= 0.82-1.00]. Subgroup analysis suggested that obesity status modified the risk of prior early C-section but did not affect the risk for prior late C-section. Preterm C-section in the first pregnancy may be associated with subsequent pre-eclampsia regardless of prior pre-eclampsia status.

The objective of this study was to identify factors associated with an increased risk of post-operative wound infection in women with chorioamnionitis who undergo cesarean delivery. We conducted a retrospective cohort study of women with clinical chorioamnionitis who underwent cesarean delivery at a tertiary-care center between June 2010 and May 2013. Demographic data, labor and delivery details and post-operative outcomes were collected. Women with and without post-operative wound infections were compared. Of 213 women with clinical chorioamnionitis who underwent cesarean delivery, 32 (15%) developed wound infections. Women with wound infection were more likely to have a body mass index (BMI) greater than or equal to 40 (p = 0.04), chronic hypertension (p = 0.03), leukocytosis on presentation (p = 0.046) or use tobacco (p = 0.002). Women who received ertapenem postpartum were less likely to develop wound infection than those who did not receive antibiotics (p = 0.02) or those that received ampicillin, gentamicin and clindamycin (p = 0.005). Elevated BMI, tobacco use, chronic hypertension and leukocytosis at admission were associated with an increased risk of wound infection. Ertapenem appeared to reduce the risk of post-operative wound infections in women who had chorioamnionitis and underwent cesarean delivery. This could be considered as a treatment option for this high-risk population.

The incidence of opioid-related death in women has increased 5-fold over the past decade. For many women, their initial opioid exposure will occur in the setting of routine medical care. Approximately 1 in 3 deliveries in the United States is by cesarean, and opioids are commonly prescribed for postsurgical pain management. The objective of this study was to determine the risk that opioid-naïve women prescribed opioids after cesarean delivery will subsequently become consistent prescription opioid users in the year following delivery and to identify predictors for this behavior. We identified women in a database of commercial insurance beneficiaries who underwent cesarean delivery and who were opioid naïve in the year prior to delivery. To identify persistent users of opioids, we used trajectory models, which group together patients with similar patterns of medication filling during follow-up, based on patterns of opioid dispensing in the year following cesarean delivery. We then constructed a multivariable logistic regression model to identify independent risk factors for membership in the persistent user group. A total of 285 of 80,127 (0.36%, 95% confidence interval, 0.32-0.40), opioid-naïve women became persistent opioid users (identified using trajectory models based on monthly patterns of opioid dispensing) following cesarean delivery. Demographics and baseline comorbidity predicted such use with moderate discrimination (c statistic = 0.73). Significant predictors included a history of cocaine abuse (risk, 7.41%; adjusted odds ratio, 6.11, 95% confidence interval, 1.03-36.31) and other illicit substance abuse (2.36%; adjusted odds ratio, 2.78, 95% confidence interval, 1.12-6.91), tobacco use (1.45%; adjusted odds ratio, 3.04, 95% confidence interval, 2.03-4.55), back pain (0.69%; adjusted odds ratio, 1.74, 95% confidence interval, 1.33-2.29), migraines (0.91%; adjusted odds ratio, 2.14, 95% confidence interval, 1.58-2.90), antidepressant use (1

However, bronchopulmonary dysplasia remains a major morbidity. Preterm infants have both structural and functional lung immaturity compared with term infants, making them more likely to require resuscitation and more vulnerable to developing bronchopulmonary dysplasia. Interventions in the delivery room may affect short-term and long-term outcomes for preterm infants. The paradigm of resuscitation of preterm infants has been changing over the past decade from being interventional and invasive to be observational and gentle. Recent developments in respiratory management of preterm infants in the delivery room include oxygen supplementation and monitoring, alveolar recruitment techniques, noninvasive ventilation, new surfactant preparations, and new techniques for administration of surfactant. Providing nasal continuous positive airway pressure (CPAP rather than intubating has been identified as a potentially better practice. Experimental studies have demonstrated that early application of nasal CPAP is protective for the preterm lung and brain compared with mechanical ventilation. Several observational studies have suggested that early nasal CPAP and avoiding intubation leads to reduced oxygen requirements, intubation rates, duration of mechanical ventilation, and may decrease rates of bronchopulmonary dysplasia. Multicenter, randomized controlled trials support the use of nasal CPAP as a primary strategy in preterm babies with respiratory distress syndrome. This approach leads to a reduction in the number of infants who are intubated and given surfactant without an impact on bronchopulmonary dysplasia rates. On the other hand, half of the infants enrolled in these studies failed nasal CPAP treatment. New techniques for surfactant

Background: With the change in population policy from birth control toward encouraging birth and population growth in Iran, repeated cesarean deliveries as a main reason of cesarean section are associated with more potential adverse consequences. The aim of this research was to explore effective strategies to reduce cesarean delivery rates in Iran. Methods: A mixed methodological study was designed and implemented. First, using a qualitative approach, concepts and influencing factors of increased cesarean delivery were explored. Based on the findings of this phase of the study, a questionnaire including the proposed strategies to reduce cesarean delivery was developed. Then in a quantitative phase, the questionnaire was assessed by key informants from across the country and evaluated to obtain more effective strategies to reduce cesarean delivery. Ten participants in the qualitative study included policy makers from the Ministry of Health, obstetricians, midwives and anthropologists. In the next step, 141 participants from private and public hospitals, insurance experts, Academic Associations of Midwifery, and policy makers in Maternity Health Affairs of Ministry of Health were invited to assess and provide feedback on the strategies that work to reduce cesarean deliveries. Results: Qualitative data analysis showed four concept related to increased cesarean delivery rates including; “standardization”, “education”, “amending regulations”, and “performance supervision”. Effective strategies extracted from qualitative data were rated by participants then, using ACCEPT derived from A as attainability, C as costing, C as complication, E as effectiveness, P as popularity, and T as timing table 19 strategies were detected as priorities. Conclusions: Although developing effective strategies to reduce cesarean delivery rates is complex process because of the multi-factorial nature of increased cesarean deliveries, in this study we have achieved strategies

To compare maternal and neonatal outcomes between planned cesarean delivery and induction of labor in women with class III obesity (body mass index ≥40 kg/m(2)). In this retrospective cohort study, we identified all women with a body mass index ≥40 kg/m(2) who delivered a singleton at our institution from January 2007 to February 2013 via planned cesarean or induction of labor (regardless of eventual delivery route) at 37-41 weeks. Patients in spontaneous labor were excluded. The primary outcome was a composite of maternal morbidity including death as well as operative, infection, and thromboembolic complications. The secondary outcome was a neonatal morbidity composite. Additional outcomes included individual components of the composites. Student t, χ(2), and Fisher exact tests were used for statistical analysis. To calculate adjusted odds ratios, covariates were analyzed via multivariable logistic regression. There are 661 mother-infant pairs that met enrollment criteria-399 inductions and 262 cesareans. Groups were similar in terms of prepregnancy weight, pregnancy weight gain, and delivery body mass index. Of the 399 inductions, 258 had cervical ripening (64.7%) and 163 (40.9%) had a cesarean delivery. After multivariable adjustments, there was no significant difference in the maternal morbidity composite (adjusted odds ratio, 0.98; 95% confidence interval, 0.55-1.77) or in the neonatal morbidity composite (adjusted odds ratio, 0.81; 95% confidence interval, 0.37-1.77) between the induction and cesarean groups. In term pregnant women with class III obesity, planned cesarean does not appear to reduce maternal and neonatal morbidity compared with induction of labor. Copyright © 2014 Elsevier Inc.

Friedman, the United Kingdom's National Institute for Health and Care Excellence (NICE), and the American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) support different active labor diagnostic guidelines. Our aims were to compare likelihoods for cesarean delivery among women admitted before vs in active labor by diagnostic guideline (within-guideline comparisons) and between women admitted in active labor per one or more of the guidelines (between-guideline comparisons). Active labor diagnostic guidelines were retrospectively applied to cervical examination data from nulliparous women with spontaneous labor onset (n = 2573). Generalized linear models were used to determine outcome likelihoods within- and between-guideline groups. At admission, 15.7%, 48.3%, and 10.1% of nulliparous women were in active labor per Friedman, NICE, and ACOG/SMFM diagnostic guidelines, respectively. Cesarean delivery was more likely among women admitted before vs in active labor per the Friedman (AOR 1.75 [95% CI 1.08-2.82] or NICE guideline (AOR 2.55 [95% CI 1.84-3.53]). Between guidelines, cesarean delivery was less likely among women admitted in active labor per the NICE guideline, as compared with the ACOG/SMFM guideline (AOR 0.55 [95% CI 0.35-0.88]). Many nulliparous women are admitted to the hospital before active labor onset. These women are significantly more likely to have a cesarean delivery. Diagnosing active labor before admission or before intervention to speed labor may be one component of a multi-faceted approach to decreasing the primary cesarean rate in the United States. The NICE diagnostic guideline is more inclusive than Friedman or ACOG/SMFM guidelines and its use may be the most clinically useful for safely lowering cesarean rates. © 2017 Wiley Periodicals, Inc.

Cesarean delivery is performed frequently worldwide, and follow-up studies that report complications at subsequent surgery are warranted. The aim of the study was to investigate the association between a previous abdominal delivery and complications during a subsequent hysterectomy and to estimate the fraction of complications that are driven by the presence of adhesions. This was a longitudinal population-based register study of 25354 women who underwent a benign hysterectomy at 46 hospital units in Sweden 2000-2014. Adhesions were found in 45% of the women with a history of cesarean delivery. Organ injury affected 2.2% of the women. The risk of organ injury (adjusted odds ratio, 1.74; 95% confidence interval, 1.41-2.15) and postoperative infection (adjusted odds ratio, 1.26; 95% confidence interval, 1.15-1.39) was increased with previous cesarean delivery, irrespective of whether adhesions were present or not. The direct effect on organ injury by a personal history of cesarean delivery was estimated to 73%, and only 27% was mediated by the presence of adhesions. Previous cesarean delivery was a predictor of bladder injury (adjusted odds ratio, 1.86; 95% confidence interval, 1.40-2.47) and bowel injury (adjusted odds ratio, 1.83; 95% confidence interval, 1.10-3.03), but not ureter injury. A personal history of other abdominal surgeries was associated with bowel injury (adjusted odds ratio, 2.27; 95% confidence interval, 1.37-3.78), and the presence of endometriosis increased the risk of ureter injury (adjusted odds ratio, 2.15; 95% confidence interval, 1.34-3.44). Previous cesarean delivery is associated with an increased risk of complications during a subsequent hysterectomy, but the risk is only partly attributable to the presence of adhesions. Previous cesarean delivery and presence of endometriosis were major predisposing factors of organ injury at the time of the hysterectomy, whereas background and perioperative characteristics were of minor importance
Full Text Available Endothelial dysfunction is key to the development of atherosclerosis. Preterm delivery foreshadows later maternal cardiovascular disease (CVD, but it is not known if endothelial dysfunction also occurs. We prospectively measured circulating biomarkers of endothelial dysfunction in pregnant women with preterm or term delivery.We conducted a case-control study nested within a large prospective epidemiological study of young, generally healthy pregnant women. Women who delivered preterm (<37 completed weeks gestation, n = 240 and controls who delivered at term (n = 439 were included. Pregnancies complicated by preeclampsia were analyzed separately. Circulating endothelial dysfunction biomarkers included soluble intercellular adhesion molecule-1 (sICAM-1, vascular cell adhesion molecule-1 (sVCAM-1 and soluble E-selectin (sE-selectin.Elevated levels of sICAM-1 and sVCAM-1 were positively associated with preterm delivery independent of usual risk factors. At entry (∼16 wks, the adjusted odds ratio (AOR was 1.73 (95% confidence interval (CI 1.09-2.74 for the highest quartile of sICAM-1 versus the lowest quartile and for sVCAM-1 the AOR was 2.17 (95% CI 1.36-3.46. When analysis was limited to cases with a spontaneous preterm delivery, the results were unchanged. Similar results were obtained for the 3rd trimester (∼30 wks. Elevated sE-selectin was increased only in preterm delivery complicated by preeclampsia; risk was increased at entry (AOR 2.32, 95% CI 1.22-4.40 and in the 3rd trimester (AOR 3.37, 95% CI 1.78-6.39.Impaired endothelial function as indicated by increased levels of soluble molecules commonly secreted by endothelial cells is a pathogenic precursor to CVD that is also present in women with preterm delivery. Our findings underscore the need for follow-up studies to determine if improving endothelial function prevents later CVD risk in women.

The effect of screening and treatment for abnormal vaginal flora on the reduction of preterm deliveries remains controversial. We evaluated whether this screening and treatment reduces the preterm delivery rate for general-population pregnant women. Pregnant women of the Intervention group (n = 574) underwent the screening test and the treatment of vaginal metronidazole during the early second trimester, and those of the Control group (n = 1,161) did not. We compared the preterm delivery rate between these two groups. We also compared the profiles of vaginal flora of the preterm delivery cases with those of the pregnant women with a normal course. There was no significant difference in the preterm delivery rate between these two groups. However, in the preterm delivery cases, a frequent shift to intermediate flora was observed not before but after the screening in the Intervention group. This shift may explain why most of the previous studies failed in regard to the prevention of preterm deliveries. PMID:24762852

To validate Grobman nomogram for predicting vaginal birth after cesarean delivery (VBAC) in a French population and adapt it. Multicenter retrospective study of maternal and obstetric factors associated with VBAC between May 2012 and May 2013 in 6 maternity units. External validation and adaptation of the prenatal and intrapartum Grobman nomograms for vaginal birth prediction after cesarean delivery in a French cohort. The study included 523 women with previous cesarean deliveries; 70% underwent a trial of labor for a subsequent delivery (n=367) with a success rate of 65% (n=240). In the univariate analysis, 5 factors were associated with successful VBAC: previous vaginal delivery before the cesarean (P6 (P=0.03). A potentially recurrent indication (defined as arrest of dilation or descent as the indication for the previous cesarean) (P=0.039), a hypertensive disorder during pregnancy (P=0.05), and labor induction (P=0.017) were each associated with failed VBAC. External validation of the prenatal and intrapartum Grobman nomograms showed an area under the ROC curve of 69% (95% CI: 0.638, 0.736) and 65% (95% CI: 0.599, 0.700) respectively. Adaptation of the nomogram to the French cohort resulted in the inclusion of the following factors: maternal age, body mass index at last prenatal visit, hypertensive disorder, gestational age at delivery, recurring indication, cervical dilatation, and induction of labor. Its area under the curve to predict successful VBAC was 78% (95% CI: 0.738, 0.825). The nomogram to predict VBAC developed by Grobman et al. is validated in the French population. Adaptation to the French population, by excluding ethnicity, appeared to improve its performance. Impact of the nomogram use on the caesarean section rate has to be validated in a randomized control trial. Copyright © 2017. Published by Elsevier Masson SAS.

We compared the prevalence and risk of lower urinary tract symptoms in healthy primiparous women in relation to vaginal birth or elective cesarean section 9 months after delivery. We performed a prospective controlled cohort study including 220 women delivered by elective cesarean section and 215 by vaginal birth. All subjects received an identical questionnaire on lower urinary tract symptoms in late pregnancy, at 3 and 9 months postpartum. Two hundred twenty subjects underwent elective cesarean section, and 215 subjects underwent vaginal delivery. After childbirth, the 3-month questionnaire was completed by 389/435 subjects (89%) and the 9-month questionnaire by 376/435 subjects (86%). In the vaginal delivery cohort, all lower urinary tract symptoms increased significantly at 9 months follow-up. When compared to cesarean section, the prevalence of stress urinary incontinence (SUI) after vaginal delivery was significantly increased both at 3 (p delivery was the only obstetrical predictor for SUI [relative risk (RR) 8.9, 95% confidence interval (CI) 1.9-42] and for urinary urgency (RR 7.3 95% CI 1.7-32) at 9 months follow-up. A history of SUI before pregnancy (OR 5.2, 95% CI 1.5-19) and at 3 months follow-up (OR 3.9, 95% CI 1.7-8.5) were independent predictors for SUI at 9 months follow-up. Vaginal delivery is associated with an increased risk for lower urinary tract symptoms 9 months after childbirth when compared to elective cesarean section.
Full Text Available Objective: Due to the increased number of labour inductions in women with previous cesarean section, the risk of uterine rupture leading to maternal and fetal mortality is also increasing. In this manuscript, we aimed to review the risk of uterine rupture in labour induction of women with prior cesarean section. Materials and Methods: Data from 48 reports belonging to the years 1994 through 2015, obtained via a search on various internet sources by the words "labour induction", "previous cesarean", "uterine scar", "uterine rupture" were used to characterize the risk factors, methods and complications of labour induction in women with previous cesarean section. Results: The success of labour induction after a previous cesarean section is related to a history of prior vaginal delivery, the indication of prior cesarean delivery, age, body mass index and ethnicity. The risk of uterine rupture is lower with mechanical dilatators compared to prostaglandins when they are used for cervical ripening. Oxytocin is associated with an increased risk of uterine rupture in such women but induction and augmentation of labor is an option for all women undergoing a trial of labor after cesarean section. Although some guidelines discourage the use of prostaglandin E1, some others support the use of prostaglandin E1 or E2 for induction of labor in rare situations provided that the women be informed of the higher risk of uterine rupture. Conclusions: Previous uterine surgery is the most common underlying reason for an increased risk of uterine rupture in subsequent trial of labour. When indicated, before considering a labour induction in these patients, a risk assessment should be performed based on various parameters. For prediction of uterine rupture, lower uterine segment may be measured by ultrasonography. Individually selected methods for labour induction should be discussed with the patients since they are mostly associated with increased risk of uterine

We aimed to determine the potential value of maternal serum levels of acute phase reactants in the prediction of preterm delivery in women with threatened preterm labor (TPL). Ninety-one pregnant women diagnosed with TPL and 83 healthy pregnant women as a control group were included in this prospective controlled study. All the pregnant women were followed until delivery and obstetric data and the serum levels of acute phase reactants were recorded for each participant. The study group was further divided into two groups according to the gestational age at delivery, which include women delivering prematurely and the ones who gave birth at term. Serum albumin levels were significantly lower and mean serum ferritin levels were significantly higher in the study groups when compared the control group. Although an association between decreased serum albumin level and TPL, also between increased serum ferritin levels and preterm birth and low birth weight were demonstrated, more extensive studies are needed to clarify the potential use of the acute phase reactants in the prediction of preterm birth.

The aim of this study was to evaluate the risk of obstructive sleep apnea (OSA) to preterm delivery (PTD), using the Berlin Questionnaire (BQ). This was a large, prospective cohort study among pregnant Thai women. The BQ was employed for symptom-based OSA screening during the second trimester, and PTD was recorded in 1345 pregnant women. Multivariate models were applied in controlling for potential confounders. The overall prevalence of the high risk of OSA was 10.1 %, and it was significantly associated with pre-pregnancy body mass index and score on the Perceived Stress Scale. An adjusted odds ratio for PTD in women with a high risk of OSA was 2.00 (95 % confidence intervals (CIs) = 1.20, 3.34). Stratified analyses, after adjusting for confounding factors, indicated that a high risk of OSA was associated with an increased risk of spontaneous preterm delivery (odds ratio (OR) = 2.45, 95 % CI = 1.20, 5.02), but not with preterm premature rupture of membranes (OR = 1.61, 95 % CI = 0.61, 4.26), and medically indicated preterm delivery (OR = 1.83, 95 % CI = 0.72, 4.64). Pregnant women with a high risk of OSA are at an increased risk of having PTD, compared with pregnant women with a low risk of OSA.

To determine the prevalence of wound infection following cesarean delivery, risk factors, common bacterial pathogens and their antibiotic sensitivity. The study population consisted of 5787 cesarean deliveries. All of the patients received 2 g doses of cephazolin perioperatively for antibiotic prophylaxis. Patients with wound infection who had two doses of 1 g cephazolin postoperatively and who were continued on oral preparations of 500 mg of cephuroxime twice daily for 5 days after hospital discharge were included in Group A. Patients with wound infection whose postoperative antibiotics and antibiotics after discharge were omitted were included in Group B. Patient related variables, gestational age, co-morbidities, cesarean section indications, neonatal intensive care requirements were assessed. Risk factors were evaluated according to the type of the procedure (elective or emergent) and administered antibiotic protocol. The incidence of wound infection following cesarean section was 0,37% in elective operations and 5,4% in emergency cases. On the other hand, wound infection rate was found to be 1,35% in antibiotic receiving group (Group A) and 1,12% in the group not receiving antibiotics (Group B). Increased rate of wound infections were remarkable in emergency cases and postoperative antibiotics did not have a major impact in reducing the rate of wound infection following cesarean section.

We present a case of acute colonic pseudo obstruction (Ogilvie′s Syndrome) post Cesarean Section in a 35 years old Arabic patient with co-existing systemic lupus erythematosus. Due to developed complications-perforations of the colon and peritonitis, the patient required laparotomy and right hemicolectomy. To our knowledge, this is the first case of Ogilvie′s syndrome, reported from the Middle East. The possible etiologic factors, pathophysiology, clinical presentation, diagnostic work up and...
Full Text Available Arrhythmias in pregnancy are common and may cause concern for the well-being of both mother and fetus. Generally, no previous history of heart disease is elicited and majority of the arrhythmias are benign. Bradycardia is commonly seen following subarachnoid block for cesarean section. However, the incidence of subsequent heart block is low. This case report highlights the occurrence of perioperative arrhythmias following sympathetic blockade in pregnant patients and their early detection by vigilant monitoring.

The transversus abdominis plane (TAP) block is an effective method of providing postoperative analgesia in patients undergoing midline abdominal wall incisions. We evaluated its analgesic efficacy over the first 48 postoperative hours after cesarean delivery performed through a Pfannensteil incision, in a randomized controlled, double-blind, clinical trial.

To evaluate whether supplemental perioperative oxygen decreases surgical site wound infections or endometritis. This was a prospective, randomized trial. Patients who were to undergo cesarean delivery were recruited and randomly allocated to either 30% or 80% oxygen during the cesarean delivery and for 1 hour after surgery. The obstetricians and patients were blinded to the concentration of oxygen used. Patients were evaluated for wound infection or endometritis during their hospital stay and by 6 weeks postpartum. The primary end point was a composite of either surgical site infection or endometritis. Eight hundred thirty-one patients were recruited. Of these, 415 participants received 30% oxygen perioperatively and 416 received 80% oxygen. The groups were well matched for age, race, parity, diabetes, number of previous cesarean deliveries, and scheduled compared with unscheduled cesarean deliveries. An intention-to-treat analysis was used. There was no difference in the primary composite outcome (8.2% in women who received 30% oxygen compared with 8.2% in women who received 80% oxygen, P=.89), no difference in surgical site infection in the two groups (5.5% compared with 5.8%, P=.98), and no significant difference in endometritis in the two groups (2.7% compared with 2.4%, P=.66), respectively. Women who received 80% supplemental oxygen perioperatively did not have a lower rate of a surgical site infection or endometritis as compared with women who received 30% supplemental oxygen concentration.

The dramatic rise in cesarean delivery rates worldwide in recent decades, without evidence of a concomitant decrease in cerebral palsy rates, has raised concerns about its potential negative consequences for maternal and infant health. In 2014, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine jointly published an Obstetric Care Consensus for safe prevention of the primary cesarean delivery. We sought to assess whether modification of our protocol to implement these recommendations helped to decrease our primary cesarean delivery rate safely. This is a before-and-after retrospective cohort study at a university referral hospital. In March 2014, the threshold for defining active labor changed from 4 to >6 cm and arrest of first-stage labor from lack of cervical change despite regular contractions after 3 hours of oxytocin administration with amniotomy and epidural anesthesia to no change after 4 hours of adequate or 6 hours of inadequate contractions in women with an epidural. The definition of second-stage arrest of labor changed simultaneously from lack of progress for 3 hours with adequate contractions in women with epidural anesthesia to no progress for ≥4 hours in nulliparas or 3 hours in multiparas with an epidural. We compared maternal and neonatal outcomes over two 1 year periods: from March 2013 to February 2014 (before, preguideline) and from June 2014 to May 2015 (after, postguideline). We included all women with singleton pregnancies at ≥37 weeks' gestation, in vertex presentation, in spontaneous or induced labor, and with epidural anesthesia. We excluded women with an elective or previous cesarean delivery and those with obstetric or fetal complications. This study included 3283 and 3068 women in the before and after periods, respectively. The groups had similar general and obstetric characteristics. The global cesarean delivery rate decreased significantly from 9.4% in the preguideline to 6.9% in

Objective of study is to compare peri-operative complications between exteriorization and intraabdominal repair of uterus after cesarean delivery. Study Design: Randomized controlled trial. Place and Duration of Study: Obstetrics and Gynecology Department of Pakistan Ordinance Factory Hospital, Wah Cantt, from 1st April 2010 to 30th September 2010. Material and Methods: Patients planned for 1st cesarean section under spinal anesthesia were randomly allocated by lottery method to exteriorized (A) or in situ uterine repair (B) group. Patients with history of uterine surgeries and cesarean section were excluded from study. Variables analyzed were operation time, peri-operative hemoglobin (Hb) fall, nausea and vomiting during the cesarean delivery. Results: The study analyzed 170 patients and divided them in 2 groups, having no significant difference with respect to maternal demographics, procedure statistics and indication of cesarean section. Significant difference was observed in operation time being 32.78 min in exteriorized group and 36.38 min in situ uterine repair group (p-value 0.0001). Hb percent fall was 0.85 g/dl and 0.92 g/dl respectively in both groups (p-value 0.62) Nausea and vomiting was 23.5 percent in group A and 11.8 percent in group B (p-value 0.02, 0.04 respectively) Conclusion: Peri-operative complications like operative time and Hb fall are less in uterine repair after temporary exteriorization as compared to intra-abdominal repair of uterus after cesarean delivery. Nausea and vomiting were increased in exteriorized group but proper regional anesthetic technique and achieving adequate analgesia can reduce patient discomfort. (author)

Along with the rising prevalence of obesity, rates of gestational diabetes mellitus (GDM) and associated adverse outcomes also have increased. We conducted a population-based, retrospective cohort study to assess the association of weight gain between pregnancies with cesarean delivery for the subsequent pregnancy among women with a history of GDM. Using linked birth-certificate data for women with at least two singleton births in Washington State during the period from 1992-2005, we identified 2,753 women with GDM who delivered vaginally at the baseline pregnancy (first pregnancy on record). The interpregnancy weight change (subsequent-baseline prepregnancy weight) for each woman was calculated and assigned to one of three categories: weight loss (more than 10 lb), weight stable (+/-10 lb), or weight gain (more than 10 lb). Multiple logistic regression was used to calculate the risk (odds ratio [OR]) of cesarean delivery at the subsequent pregnancy among the weight-gain and weight-loss groups relative to the weight-stable category. Among 2,581 eligible women, 10.9% lost more than 10 lb between pregnancies, 54.0% were weight-stable, and 35.1% gained more than 10 lb. Women who gained more than 10 lb had an adjusted OR for subsequent cesarean delivery of 1.70 (95% confidence interval [CI] 1.16-2.49, 9.7% of women who gained weight), whereas the adjusted OR for women who lost weight was 0.55 (95% CI 0.28-1.10, 4.7% of women who lost weight). Women with a history of GDM who gained more than 10 lb between pregnancies are at increased risk of future cesarean delivery. Appropriate weight management among women with a history of GDM may result in decreased cesarean delivery rates along with decreases in associated excess risks and costs. II.

Cesarean delivery may reduce placental-fetal transfusion and thus increase the risk of early childhood anemia compared with vaginal delivery, but this notion has not been carefully studied in longitudinal cohorts. The aim was to assess the association of cesarean delivery with anemia in infants and children in 2 longitudinal Chinese birth cohorts from different socioeconomic settings. Cohort 1 was recruited from 5 counties in northeastern China and cohort 2 from 21 counties or cities in southeastern China. Cohort 1 involved 17,423 infants born during 2006-2009 to mothers with early pregnancy baseline hemoglobin concentrations ranging from 100 to 177 g/L, whereas cohort 2 involved 122,777 children born during 1993-1996 to mothers with baseline hemoglobin concentrations ranging from 60 to 190 g/L. The main outcomes were anemia at 6 and 12 mo in cohort 1 and at 58 mo in cohort 2. Multiple logistic regressions were used to estimate adjusted ORs of anemia for cesarean compared with vaginal delivery. Stratified analyses were performed by pre- and postlabor cesarean delivery and according to maternal baseline hemoglobin concentration (≤109, 110-119, 120-129, and ≥130 g/L). Cesarean delivery was not associated with anemia at 6 mo in cohort 1 (adjusted OR: 1.05; 95% CI: 0.93, 1.19); however, cesarean delivery was associated with increased anemia at 12 mo in cohort 1 (adjusted OR: 1.19; 95% CI: 1.04, 1.37) and at 58 mo in cohort 2 (adjusted OR: 1.11; 95% CI: 1.08, 1.15). The positive associations for anemia at 12 and 58 mo were consistent across maternal hemoglobin subgroups and persisted for cesarean delivery subtypes. Cesarean delivery is likely associated with anemia in children, which suggests a possible need for exploring changes in obstetric care that might prevent anemia in cesarean-delivered children. © 2015 American Society for Nutrition.

Little is known about the relationship between disability and mode of delivery. Prior research has indicated elevated risk of cesarean delivery among women with certain disabilities, but has not examined patterns across multiple types of disability or by parity. This study sought to determine whether physical, sensory, or intellectual and developmental disabilities are independently associated with primary cesarean delivery. We conducted a retrospective cohort study of all deliveries in California from 2000 to 2010 using linked birth certificate and hospital discharge data. We identified physical, sensory, and intellectual and developmental disabilities using International Classification of Diseases, 9th revision, clinical modification codes. We used logistic regression to examine the association of these disabilities and primary cesarean delivery, controlling for sociodemographic characteristics and comorbidities, and stratified by parity. In our sample, 0.45% of deliveries (20,894/4,610,955) were to women with disabilities. A greater proportion of women with disabilities were nulliparous, had public insurance, and had comorbidities (e.g., gestational diabetes) compared with women without disabilities (p disabilities was twice that in women without disabilities (32.7% vs. 16.3%; p disabilities due to injuries compared with women without disabilities (57.8% vs. 16.3%; p type. More attention is needed to this population to ensure better understanding of care practices that may impact maternal and perinatal outcomes. Copyright © 2017 Jacobs Institute of Women's Health.

To determine whether sonographically measured cervical length is an effective predictive tool in women with threatened preterm labor and a history of past spontaneous preterm delivery. This was a retrospective cohort study of all women with singleton pregnancies who presented with preterm labor at less than 34 + 0 weeks' gestation and underwent sonographic measurement of cervical length in a tertiary medical center between 2007 and 2012. The accuracy of cervical length in predicting preterm delivery was compared between women with and those without a history of spontaneous preterm delivery. Women with risk factors for preterm delivery other than a history of preterm delivery were excluded from both groups. Overall, 1023 women who presented with preterm labor met the study criteria, of whom 136 (13.3%) had a history of preterm delivery (past-PTD group) and 887 (86.7%) had no risk factors for preterm delivery (low-risk group). The rate of preterm delivery was significantly higher for women with a history of preterm delivery (36.8% vs 22.5%; P delivery interval in low-risk women (r = 0.32, P delivery (r = 0.07, P = 0.4). On multivariable analysis, cervical length was independently associated with the risk of preterm delivery for women in the low-risk group but not for women with a history of previous preterm delivery. For women with previous preterm delivery who presented with threatened preterm labor, cervical length failed to distinguish between those who did and those who did not deliver prematurely (area under the receiver-operating characteristics curve range, 0.475-0.506). When using standardized thresholds, the sensitivity and specificity of cervical length for the prediction of preterm delivery were significantly lower in women with previous preterm delivery than in women with no risk factors for preterm delivery. Cervical length appears to be of limited value in the prediction of preterm delivery among women with threatened preterm labor

The Portland cement industry is the main source of particulate air pollution in Kaohsiung city. Data in this study concern outdoor air pollution and the health of individuals living in communities in close proximity to Portland cement plants. The prevalence of delivery of preterm birth infants as significantly higher in mothers living within 0-2 km of a Portland cement plant than in mothers living within 2-4 km. After controlling for several possible confounders (including maternal age, season, marital status, maternal education, and infant sex), the adjusted odds ratio was 1.30 (95% I=1.09-1.54) for the delivery of preterm infants for mothers living close to he Portland cement plants, chosen at the start to be from 0 to 2 km. These data provide further support for the hypothesis that air pollution can affect he outcome of pregnancy

Objectives Vaginal delivery is a risk factor in pelvic floor disorders. We previously described changes in the pelvic floor associated with pregnancy and parturition in the squirrel monkey, a species with a human-like pattern of spontaneous age and parity associated pelvic organ prolapse. The potential to prevent or diminish these changes with scheduled cesarean section has not been evaluated. In a randomized, controlled trial, we compare female squirrel monkeys undergoing spontaneous vaginal delivery with those undergoing scheduled primary cesarean section for pelvic floor muscle volumes, muscle contrast changes, and dynamic effects on bladder neck position. Study Design Levator ani, obturator internus, and coccygeus muscle volumes and contrast uptake were assessed by magnetic resonance imaging in 20 nulliparous females examined prior to pregnancy, a few days after delivery, and 3 months post-partum. The position of bladder neck relative to boney reference line also was assessed with abdominal pressure using dynamic magnetic resonance imaging. Results Baseline measurements of 10 females randomly assigned to scheduled primary cesarean sections were not different from those of 10 females assigned to spontaneous vaginal delivery. Levator ani and obturator internus muscle volumes did not differ between groups, while volumes were reduced (p pelvic support of the bladder was not protected by this intervention suggesting that effects of pregnancy and delivery are not uniformly prevented by this procedure.

To assess birth preferences in a sample of Hungarian pregnant women and identify determinants of ambivalence or clear choices for cesarean section throughout pregnancy. Follow-up two-point questionnaire survey. University Department of Obstetrics and Gynecology in Hungary. A total of 413 women with singleton pregnancies where there was no awareness of medical contradictions to vaginal delivery, attending for routine ultrasound examination in mid-pregnancy from November 2011 to March 2012. Questionnaires completed in mid- and late pregnancy (gestational weeks 18-22 and 35-37) including the Wijma Delivery Expectancy/Experience Questionnaire A. Prevalence of women preferring cesarean section or being uncertain about what delivery route to choose, in case they had the choice; their demographic characteristics, attitudes toward birth issues and their Wijma Delivery Expectancy/Experience Questionnaire A scores, compared with women consistent in their preference for vaginal delivery. Of the 413 respondents, 365 (88.4%) were consistent in their preference for vaginal delivery. In logistic regression models the important contributors to describing preferences for cesarean section or uncertain preferences were previous cesarean section and maternal belief that cesarean section is more beneficial than vaginal delivery. The majority of pregnant women preferred vaginal delivery to cesarean section. Neither a higher Wijma Delivery Expectancy/Experience Questionnaire A score nor sociodemographic differences were important determinants of a preference for cesarean section or for an uncertain preference. On the other hand, previous cesarean section and certain preconceived maternal attitudes towards delivery were characteristic for these women. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

To evaluate the efficacy and safety of transcatheter arterial embolization of the pelvic arteries for the treatment of postpartum hemorrhage (PPH) associated with cesarean section compared with vaginal delivery. A retrospective analysis of 176 patients undergoing transcatheter arterial embolization of the pelvic arteries for PPH from January 2006 through August 2011 was conducted at two institutions. The mean patient age was 33.9 years (range, 24-46 years). Data including delivery details, hematology and coagulation results, embolization details, and clinical outcomes were collected. Technical success was defined as cessation of bleeding on angiography or angiographically successful embolization of the bleeding artery. Clinical success was defined as the obviation of repeated embolization or surgical intervention. The technical success rate was 98.8% (n = 174), and the clinical success rate was 89.7% (n = 158). Among 176 patients, 71 had cesarean sections, and 105 underwent normal vaginal deliveries. Of the 105 patients who underwent normal vaginal deliveries, 11 (10.5%) required repeat embolization or surgical intervention. Of the 71 patients who had cesarean sections, 7 (9.8%) required repeat embolization or surgical intervention. The clinical success rate and complication rate were not related to the mode of delivery. All women resumed menses after transcatheter arterial embolization, and most (n = 125) described their menses as unchanged. Subsequent spontaneous pregnancies occurred in 13 women. The cesarean mode of delivery is not a predictor of poorer outcomes of transcatheter arterial embolization; however, further study is needed to clarify this relationship. Copyright © 2013 SIR.

Obstetricians in developing countries appear generally reluctant to conduct vaginal delivery in women with a previous Cesarean because of lack of adequate facilities for optimal fetomaternal monitoring. To describe delivery outcomes among women with one previous Cesarean section at a tertiary hospital in Southeast Nigeria. This was a prospective observational study to determine maternal and perinatal outcomes of attempted vaginal birth after Cesarean sections (VBAC) following one previous Cesarean section. Analysis was done with SPSS statistical software version 17.0 for Windows using descriptive and inferential statistics at 95% level of confidence. Two thousand six hundred and ten women delivered in the center during the study period, of whom 395 had one previous Cesarean section. A total of 370 women with one previous Cesarean section had nonrecurrent indications, of whom 355 consenting pregnant women with one previous Cesarean section were studied. A majority of the women (320/355, 90.1%) preferred to have vaginal delivery despite the one previous Cesarean section. However, only approximately 54% (190/355) were found suitable for trial of VBAC, out of whom 50% (95/190 had successful VBAC. Ninety-five women (50.0%) had failed attempt at VBAC and were delivered by emergency Cesarean section while 35 women (9.8%) had emergency Cesarean section for other obstetric indications (apart from failed VBAC). There was no case of uterine rupture or neonatal and maternal deaths recorded in any group. Apgar scores of less than 7 in the first minute were significantly more frequent amongst women who had vaginal delivery when compared to those who had elective repeat Cesarean section (P=0.03). Most women who had one previous Cesarean delivery chose to undergo trial of VBAC, although only about half were considered suitable for VBAC. The maternal and fetal outcomes of trial of VBAC in selected women with one previous Cesarean delivery for non-recurrent indications were good

To assess the use and timing of scheduled cesareans and other categories of cesarean delivery and the prevalence of neonatal morbidity among cesareans in Oregon before and after the implementation of Oregon's statewide policy limiting elective early deliveries. Oregon vital statistics records, 2008-2013. Retrospective cohort study, with multivariable logistic regression, regression controlling for time trends, and interrupted time series analyses, to compare the odds of different categories of cesarean delivery and the odds of neonatal morbidity pre- and postpolicy. We analyzed vital statistics data on all term births in Oregon (2008-2013), excluding births in 2011. The odds of early-term scheduled cesareans decreased postpolicy (adjusted odds ratio [aOR], 0.70; 95 percent confidence interval [CI], 0.66-0.74). In the postpolicy period, there were mixed findings regarding assisted neonatal ventilation and neonatal intensive care unit admission, with regression models indicating higher postpolicy odds in some categories, but lower postpolicy odds after controlling for time trends. Oregon's hard stop policy limiting elective early-term cesarean delivery was associated with lower odds of cesarean delivery in the category of women who were targeted by the policy; more research is needed on impact of such policies on neonatal outcomes. © Health Research and Educational Trust.

To identify the frequency of cesarean delivery for non-obstetric indications before and after the introduction of specific measures to lower the rate of elective cesarean, and to evaluate the effectiveness of the introduced measures. In the present single-center retrospective cohort study at University Hospital Trnava, Trnava, Slovak Republic, the frequency of elective cesarean was evaluated before (January 1, 2010, to December 31, 2014) and after (January 1, 2015, to December 31, 2016) the implementation of specific measures applied in January 2015 to confirm the indications for primary cesarean delivery. The frequency of elective cesarean delivery for non-obstetric indications was compared between the two periods. Before the intervention in 2015, 229 (2.9%) of 7768 women had elective cesarean deliveries for non-obstetric indications. After implementation of the intervention, the frequency decreased to 27 (0.8%) of 3203 women (Pdelivery for non-obstetric indications was reduced significantly by introducing specific reasonable measures. These included all non-obstetric indications for cesarean delivery being approved by a leading specialist of the related department, close cooperation with professionals from other specialties, and, additionally, staff attending professional educational lectures. © 2018 International Federation of Gynecology and Obstetrics.
Full Text Available Background: Cesarean delivery is the most common surgical procedure and this prevalence is on the rise. Given these trends, cesarean wound complications, such as disruption or infection, remain an important cause of post-cesarean morbidity. Methods: We conducted a single-center randomized controlled trial that included women with viable pregnancies (≥24 weeks undergoing cesarean delivery at Motahary University Hospital, Urmia, Iran from April to November 2014. All cesarean types were included: scheduled or unscheduled and primary or repeat cesareans. Women were excluded for the following reasons: inability to obtain informed consent, immune compromising disease (e.g. AIDS, chronic steroid use, diabetic mellitus and BMI≥30. Of 266 women, 133 were randomized to staples and 133 women to suture group. Results: The mean±SD age of the staples group was 27.6±5.4 years and mean±SD age of suture was 28.7±5.9 years. Multiparity is the most frequent in both groups that by using Chi-square test, no significant differences were observed between the two groups (P=0.393. The most frequent indication for cesarean section in both groups was history of cesarean section in staple 40 cases (30.1% and suture 32 cases (24.1%. The survey was conducted using the Chi-square test was not significant (P=0.381. Pain at 6 weeks postoperatively was significantly less in the staple group (P=0.001. Operative time was longer with suture closure (4.68±0.67 versus 1.03±0.07 minute, P<0.001. The Vancouver scale score was significantly less in suture closure (6.6±0.8 versus 7.5±0.9, P=0.001. Wound disruption was significantly less in suture closure (3.8% versus 11.3%, P=0.017. Conclusion: The staple group had low pain and operation time but had a significant wound disruption and scar. The patients who have suffered a significant wound disruption were affected by age (P=0.022 and BMI (P=0.001 at compared those who were not affected by factors such as age or high BMI as

To assess the issue of hospital variations in Colombia and to contribute to the methodology on health care variations by using a model that clusters the variance between hospitals while accounting for individual-level reimbursement rates and objective health-status variables. We used data on all births (N = 11,954) taking place in a contributory-regimen insurer network in Colombia during 2007. A multilevel logistic regression model was used to account for the share of unexplained variance between hospitals. In addition, an alternative variance decomposition specification was further carried out to measure the proportion of such unexplained variance due to the region effect. Hospitals account for 20% of the variation in performing cesarean sections, whereas region explains only one-third of such variance. Variables accounting for preferences on the demand side as well as reimbursement rates are found to predict the probability of performing cesarean sections. Hospital variations explain large variances within a single-payer's network. Because this insurer company is highly regarded in terms of performance and finance, these results might provide a lower bound for the scale of hospital variation in the Colombian health care market. Such lower bound provides guidance on the relevance of this issue for Colombia. Some factors such as demand-side preferences and physician reimbursement rates increase variations in health care even within a single-payer network. This is a source of inefficiencies, threatening the quality of health care and financial sustainability. The proposed methodology should be considered in further research on health care variations.

Full Text Available During pregnancy, different froms of periodontal disease such as pregnancy gingivitis, pregnancy tumors, pregnancy stomatitis, may be encountered. But the most considerable point is the pregnant women's infection with periodontal disease and its effect on delivery and weight of newborn infants. Based on the latest researches and statistics, it is concluded that periodontal disease is an important risk factor, leading to preterm or premature delivery. On the other hand, poor hygiene, should be considered as another danger, resulting in premature delivery. Besides, the presence of a collection of oral fosobacteria in ammoniutic fluid in mothers with premature delivery, increases the probability of an oral- haematogenous connection. Moreover, prostaglandin E2, in cervicular fluid, has been considered as an index for periodontal disease activity and loss of weight at the time of birth. These findings suggest that effective steps, to prevent preterm delivery, can be taken, if women, genycologists and dentists have enough knowledge. This article focuses on the special supervision that is required to prevent the effects of hormonal changes on periodontal tissues and conversely to reduce systemic disorders resulting from periodontal disease, in pregnant woman.

To estimate the incidence of surgical-site infection with use of chlorhexidine-alcohol compared with povidone-iodine among women undergoing cesarean deliveries. This was a retrospective cohort review of 1,000 consecutive cases in women who underwent cesarean delivery over a 1-year interval. The primary outcome was any surgical-site infection within 30 days (Centers for Disease Control and Prevention criterion). Mean age and parity were equivalent (29.8±5.9 years; 2.6±1.4). Women were similar regarding baseline characteristics, including acknowledged surgical-site infection comorbidities (body mass index [BMI, calculated as weight (kg)/[height (m)]2], gestational diabetes, smoking; P>.05). Method of skin incision closure was different, with 91% among povidine-iodine compared with 81% among chlorhexidine-alcohol using staples (Pcesarean delivery (29% compared with 46%; Pinfection, the overall rate was similar between the two groups (5% [n=25] chlorhexidine and 5.8% [n=29] povidone-iodine; P=.58). In multivariable analysis and after control for potential confounders, odds for surgical-site infection remained similar between the two groups (adjusted odds ratio 0.74, 95% confidence interval 0.41-1.33; P=.32). The only significant predictor of surgical-site infection was duration of cesarean delivery, in which every 1-minute increase in duration increased the odds for infection by 1.3% (adjusted odds ratio 1.013, 95% CI 1.004-1.022; P=.004). The single significant predictor of surgical-site infection is operative time. Cleansing with povidone-iodine may be a cost-effective and equally efficacious alternative to chlorhexidine-alcohol among women undergoing cesarean deliveries. II.

Full Text Available Abstract Background Maternal cardiovascular and pulmonary events during labor and delivery may result in adverse maternal and fetal outcome. Potential etiologies include primary cardiac events, pulmonary embolism, eclampsia, maternal hemorrhage, and adverse medication events. Remifentanil patient-controlled analgesia is an alternative when conventional neuraxial analgesia for labor is contraindicated. Although remifentanil is a commonly used analgesic, its use for labor analgesia is not clearly defined. Case presentation We present an unexpected and unique case of remifentanil toxicity resulting in the need for an emergent bedside cesarean delivery. A 30-year-old G3P2 woman receiving subcutaneous heparin anticoagulation due to a recent deep vein thrombosis developed cardiopulmonary arrest during labor induction due to remifentanil toxicity. Conclusion A rapid discussion among the attending obstetric, anesthesia, and nursing teams resulted in consensus to perform an emergent bedside cesarean delivery resulting in an excellent fetal outcome. During maternal cardiopulmonary arrest, a prompt decision to perform a bedside cesarean delivery is essential to avoid significant maternal and fetal morbidity. Under these conditions, rapid collaboration among obstetric, anesthesia, and nursing personnel, and an extensive multi-layered safety process are integral components to optimize maternal and fetal outcomes.
Full Text Available Background & aim: Preterm delivery is one of the most important problems in pregnancy, as it is the primary cause of 75% of prenatal mortality and morbidities. This study aimed to determine the prevalence and risk factors for preterm delivery in Tehran, Iran. Methods:In this cross-sectional study performed in eight random hospitals from five different regions of Tehran (North, South, West, East, and center, the prevalence of preterm delivery was evaluated and the most frequent risk factors were identified. Samples were divided into preterm delivery (n=140 and term delivery (n=100 groups. Questionnaires were completed through interviews with mothers and using patient records. To analyze the data, Chi-square test was run, using SPSS version 16. Results: About 13,281 deliveries were included in the study. The highest and lowest prevalence of preterm delivery were 6.30% and 0.77% in the North and East regions of Tehran, respectively. The overall prevalence of preterm delivery was 1.52% in Tehran. In the preterm group, age ≥35 years, pre-mature rupture of membranes, bleeding, gestational hypertension, history of preterm delivery and abortion, multiple pregnancy, and preeclampsia were significantly more frequent than the term delivery group. Conclusion: Spontaneous preterm birth was one of the major causes of maternal and neonatal morbidity; therefore, identification of its risk factors would be beneficial.

Sterilization via bilateral total salpingectomy is slowly replacing partial salpingectomy, as it is believed to decrease the incidence of ovarian cancer. Our objective was to compare short-term intra and post-operative complication rates of bilateral total salpingectomy versus partial salpingectomy performed during the course of a cesarean delivery. A large series of tubal sterilizations during cesarean sections were studied in a single tertiary medical center between 1/2014 and 8/2016 before and after a policy change was made, switching from partial salpingectomy to total salpingectomy. Patients who underwent bilateral partial salpingectomy using the modified Pomeroy technique were compared with those who underwent total salpingectomy. Operative length, estimated blood loss, postpartum fever, wound infection, need for re-laparotomy, hospitalization length, and blood transfusions were compared. During the study period, 149 women met inclusion criteria. Fifty parturients underwent bilateral total salpingectomy and 99 underwent partial salpingectomy in the course of the cesarean section. Demographic, obstetrical, and surgical characteristics were similar in both groups. Mean cesarean section duration was comparable for partial salpingectomy and total salpingectomy (a median of 35 min in both groups, P = 0.92). Complications were rare in both groups with no significant differences in rates of postpartum fever, wound infection, re-laparotomy, hospitalization length, estimated blood loss, transfusions, and readmissions within 1-month postpartum. Rates of short-term complications are similar in patients undergoing bilateral partial salpingectomy and total salpingectomy during cesarean deliveries, making the latter a feasible alternative to the former.
The high incidence of PSH with most of the pharmacological and non-pharmacological methods suggests the need for multimodal protocols for prevention and management of this problem. PSH in cesarean delivery is a common daily situation facing all anesthetists; thus, future research should focus on simple and rapid protocols that can be easily applied by anesthetists with moderate and low experience with minimal need to complex devices or costly drugs.

The mode of delivery for preterm breech is still controversial, while no randomized study has been completed. The question of a protective effect of cesarean section on neonatal outcome arises. The objective of this study was to compare mortality and neonatal morbidity for children born before 35 weeks of gestation in breech presentation, depending on the route of delivery. This was a retrospective study done in University Hospital type 3 over five years, comparing neonatal mortality and different neonatal morbidity criteria for children born between 25 weeks of gestation and 34 weeks+6 days spread into two groups according to their mode of delivery: elective caesarean section before labor and vaginal delivery. Statistical analysis was performed with an adjustment for gestational age and weight of the newborn. No significant difference between the two groups was found with regard to neonatal mortality. Among the various morbidity criteria studied, only the head entrapment rate and serious traumatic injury occurrence were significantly increased in the "intent to vaginal delivery" group. pH at birth and Apgar scores at five minutes were not significantly different between the two groups. This work shows an increased risk of traumatic complications for vaginal delivery with no increase in other neonatal complications. It seems reasonable in this particular context to allow an attempt at vaginal delivery on condition of strict compliance with safety regulations relating to breech delivery.

To compare intrauterine device (IUD) use at 6 months postpartum among women who underwent intracesarean delivery (during cesarean delivery) IUD placement compared with women who planned for interval IUD placement 6 or more weeks postpartum. In this nonblinded randomized trial, women who were undergoing a cesarean delivery and desired an IUD were randomized to intracesarean delivery or interval IUD placement. The primary outcome was IUD use at 6 months postpartum. A sample size of 112 (56 in each group) was planned to detect a 15% difference in IUD use at 6 months postpartum between groups. From March 2012 to June 2014, 172 women were screened and 112 women were randomized into the trial. Baseline characteristics were similar between groups. Data regarding IUD use at 6 months postpartum were available for 98 women, 48 and 50 women in the intracesarean delivery and interval groups, respectively. A larger proportion of the women in the intracesarean delivery group were using an IUD at 6 months postpartum (40/48 [83%]) compared with those in the interval group (32/50 [64%], relative risk 1.3, 95% confidence interval 1.02-1.66). Among the 56 women randomized to interval IUD insertion, 22 (39%) of them never received an IUD; 14 (25%) never returned for IUD placement, five (9%) women declined an IUD, and three (5%) had a failed IUD placement. Intrauterine device placement at the time of cesarean delivery leads to a higher proportion of IUD use at 6 months postpartum when compared with interval IUD placement. I.
Conclusion: We found that HCA was significantly correlated with lower gestational age, higher CRP level of preterm infants, higher maternal WBC count, and a higher rate of prolonged PROM. Our results demonstrate a significant association between HCA with an elevated CRP level in preterm infants. These findings further confirmed the association between maternal inflammation and preterm deliveries.
Full Text Available David M Haas, Tara Benjamin, Renata Sawyer, Sara K QuinneyDepartment of Obstetrics and Gynecology, Indiana University School of Medicine, Indianapolis, IN, USAAbstract: Administration of short-term tocolytic agents can prolong pregnancy for women in preterm labor. Prolonging pregnancy has many benefits because it allows for other proven interventions, such as antenatal corticosteroid administration, to be accomplished. This review provides an overview of currently utilized tocolytic agents and the evidence demonstrating their efficacy for prolonging pregnancy by at least 48 hours. General pharmacological principles for the clinician regarding drugs in pregnancy are also briefly discussed. In general, while the choice of the best first-line short-term tocolytic drug is not clear, it is evident that use of these agents has a clear place in current obstetric therapeutics.Keywords: tocolytics, short-term, preterm delivery

To assess whether a shared decision-making intervention decreases the quantity of oxycodone tablets prescribed after cesarean delivery. A tablet computer-based decision aid formed the basis of a shared decision-making session to guide opioid prescribing after cesarean delivery. Women first received information on typical trajectories of pain resolution and expected opioid use after cesarean delivery and then chose the number of tablets of 5 mg oxycodone they would be prescribed up to the institutional standard prescription of 40 tablets. From April 11, 2016, to June 10, 2016, 105 women were screened, 75 were eligible, and 51 consented to participate; one patient was excluded after enrollment as a result of prolonged hospitalization. The median number of tablets (5 mg oxycodone) women chose for their prescription was 20.0 (interquartile range 15.0-25.0), which was less than the standard 40-tablet prescription (Pleftover opioid medication after treatment of acute postcesarean pain.

Media interest in cesarean delivery has grown in recent years driven both by rising cesarean delivery rates and the decision by the American College of Obstetrics and Gynecology (ACOG) to permit elective cesarean (EC) delivery. A content analysis of United States newspaper and magazine articles from 2000 to 2013 (n = 131 articles) was completed to understand how the news media portrays ECs. The majority of articles (71.8%) emphasized reasons to support women having an EC, while 38.2 percent of the articles exhibited themes of physician support for ECs. Relatively few articles mentioned reasons against ECs either from the women's perspective (11.5%) or the practitioners' (3.8%). The most common themes given for women choosing ECs were convenience/scheduling (48.9%), avoidance of pain or fear of labor (29.8%), and physical harm to women from vaginal birth (17.6%). Doctors' perspectives were less prevalent in the media than women's perspectives, but when mentioned they were almost exclusively in support of ECs for reasons including avoiding malpractice (28.2%), avoiding physical harm to the woman or baby (16.8%), and timing/scheduling (14.5%). Media coverage suggests ECs are widely accepted by both women and doctors, with women choosing an EC mainly for convenience/scheduling and fear. However, 43 percent of doctors surveyed by ACOG said they were not willing to perform the procedure, and surveys report that mothers rarely request an EC. © 2015 Wiley Periodicals, Inc.

Women at risk for delayed onset of lactation are often advised to pump their breasts before lactogenesis stage II to hasten the timing of this process. The effectiveness of this clinical practice has not been previously evaluated. This study investigates the effects of breast pumping before the onset of lactation on early milk transfer and subsequent breastfeeding duration among women giving birth by cesarean delivery. Sixty women were randomly assigned to either the pumping group (n = 30), which used a double electric breast pump for six 10- to 15-minute sessions from 24 to 72 hours postpartum, or to the control group (n = 30), which held the pump to their breasts without suction for the same amount of time. Milk transfer was assessed by test weighing infants before and after 3 breastfeeding sessions daily. Test weight data were fitted to a second-order polynomial curve, to predict milk transfer over time. Breast pumping between 24 and 72 hours after cesarean delivery did not improve milk transfer. Participants in the pumping group tended to have lower milk transfer than did controls. Primiparae in the pumping group breastfed for ~5 months less than their counterparts in the control group; however, this difference was not statistically significant. Breast pumping did not improve milk transfer during the first 72 hours postpartum and may negatively affect breastfeeding duration among primiparous women. lactation, lactogenesis, breast milk, breast pumping, milk expression, breastfeeding, cesarean delivery.

The objective of this study was to determine whether the use of cyanoacrylate skin glue following subcuticular skin closure was associated with a decrease in wound outcomes in comparison with subcuticular closure plus Steri-strips at cesarean delivery. This was a retrospective cohort study of patients undergoing cesarean delivery at a single center over a two-year period. The primary outcome of wound infection and secondary outcomes of wound separation and composite wound complication rate were assessed throughout the six-week postpartum period. Of 660 women who met inclusion criteria, 35 (5.3%) experienced a wound infection and 90 (13.6%) experienced a wound separation. The composite wound complication rate was 16.4% (n = 108). Of the 515 cases with a skin coverage method noted, use of skin glue was associated with a marginal decrease in wound infections (p = 0.057), as well as a significantly reduced incidence of wound separation (p = 0.03) and composite wound complications (p = 0.006). Cyanoacrylate skin glue may be superior to Steri-strips for wound separation and composite wound complication rates when utilized with subcuticular suture at the time of cesarean delivery and may yield some benefit for prevention of wound infection.

To determine the safety and efficacy of using misoprostol vaginally for second-trimester abortion in women with a single previous cesarean delivery. This prospective observational study was carried out at a university hospital in Egypt with 50 pregnant women with 1 previous cesarean delivery; a gestation of at least 16 weeks but less than 20 weeks (group 1) or 20 or more weeks (group 2); and a need to terminate the pregnancy. The regimen was 4 doses of 200 microg of misoprostol applied vaginally every 4 hours daily, with a 12-hour nightly rest from misoprostol applications, until contractions appeared but not for more than 72 hours. The primary outcome was the induction-to-abortion interval. There were no cases of uterine rupture. Abortion within the study protocol occurred in 45 of the 50 women, for a 90% success rate. There was no significant difference in the induction-to-abortion interval between the 2 groups. Inducing abortion with lower misoprostol doses appear to be safe and effective throughout the second trimester in women with a single previous cesarean delivery. Larger randomized trials are needed to validate these results.

Full Text Available The aim of this survey was to review cesarean delivery anesthetic practices. An online survey was sent to members of the Society of Obstetric Anesthesia and Perinatology (SOAP. The mode of anesthesia, preferred neuraxial local anesthetic and opioid agents, postoperative analgesic regimens, and monitoring modalities were assessed. 384 responses from 1,081 online survey requests were received (response rate = 36%. Spinal anesthesia is most commonly used for elective cesarean delivery (85% respondents, with 90% of these respondents preferring hyperbaric bupivacaine 0.75%. 79% used intrathecal fentanyl and 77% used morphine (median [range] dose 200 mcg [50–400]. 91% use respiratory rate, 61% use sedation scores, and 30% use pulse oximetry to monitor for postoperative respiratory depression after administration of neuraxial opioids. Postoperative analgesic regimens include: nonsteroidal anti-inflammatory agents, acetaminophen, oxycodone, and hydrocodone by 81%, 45%, 25%, and 27% respondents respectively. The majority of respondents use spinal anesthesia and neuraxial opioids for cesarean delivery anesthesia. There is marked variability in practices for monitoring respiratory depression postdelivery and for providing postoperative analgesia. These results may not be indicative of overall practice in the United States due to the select group of anesthesiologists surveyed and the low response rate.

To study the efficacy and safety of preoperative intravenous tranexamic acid to reduce blood loss during and after elective lower-segment cesarean delivery. A single-blind, randomized placebo-controlled study was undertaken of women undergoing elective lower-segment cesarean delivery of a full-term singleton pregnancy at a center in Cairo, Egypt, between November 2013 and November 2014. Patients were randomly assigned (1:1) using computer-generated random numbers to receive either 1g tranexamic acid or 5% glucose 15 minutes before surgery. Preoperative and postoperative complete blood count, hematocrit values, and maternal weight were used to calculate the estimated blood loss (EBL) during cesarean, which was the primary outcome. Analyses included women who received their assigned treatment, whose surgery was 90 minutes or less, and who completed follow-up. Analyses included 100 women in each group. Mean EBL was significantly higher in the placebo group (700.3 ± 143.9 mL) than in the tranexamic acid group (459.4 ±7 5.4 mL; Pcesarean delivery.

To develop a model based on non-invasive clinical parameters to predict the probability of imminent preterm delivery (delivery within 48 h) in women with preterm premature rupture of membranes (PPROM), and to determine if additional invasive test results improve the prediction of imminent delivery based on the non-invasive model. Transvaginal ultrasonographic assessment of cervical length was performed and maternal serum C-reactive protein (CRP) and white blood cell (WBC) count were determined immediately after amniocentesis in 102 consecutive women with PPROM at 23-33+6 weeks. Amniotic fluid (AF) obtained by amniocentesis was cultured and interleukin-6 (IL-6) levels and WBC counts were determined. Serum CRP, cervical length, and gestational age were chosen for the non-invasive model (model 1), which has an area under the curve (AUC) of 0.804. When adding AF IL-6 as an invasive marker to the non-invasive model, serum CRP was excluded from the final model (model 2) as not significant, whereas AF IL-6, cervical length, and gestational age remained in model 2. No significant difference in AUC was found between models 1 and 2. The non-invasive model based on cervical length, gestational age, and serum CRP is highly predictive of imminent delivery in women with PPROM. However, invasive test results did not add predictive information to the non-invasive model in this setting.

Background The incidence of opioid-related death in women has increased five-fold over the past decade. For many women, their initial opioid exposure will occur in the setting of routine medical care. Approximately 1 in 3 deliveries in the U.S. is by Cesarean and opioids are commonly prescribed for post-surgical pain management. Objective The objective of this study was to determine the risk that opioid naïve women prescribed opioids after Cesarean delivery will subsequently become consistent prescription opioid users in the year following delivery, and to identify predictors for this behavior. Study Design We identified women in a database of commercial insurance beneficiaries who underwent Cesarean delivery and who were opioid-naïve in the year prior to delivery. To identify persistent users of opioids, we used trajectory models, which group together patients with similar patterns of medication filling during follow-up, based on patterns of opioid dispensing in the year following Cesarean delivery. We then constructed a multivariable logistic regression model to identify independent risk factors for membership in the persistent user group. Results 285 of 80,127 (0.36%, 95% confidence interval 0.32 to 0.40), opioid-naïve women became persistent opioid users (identified using trajectory models based on monthly patterns of opioid dispensing) following Cesarean delivery. Demographics and baseline comorbidity predicted such use with moderate discrimination (c statistic = 0.73). Significant predictors included a history of cocaine abuse (risk 7.41%; adjusted odds ratio 6.11, 95% confidence interval 1.03 to 36.31) and other illicit substance abuse (2.36%; adjusted odds ratio 2.78, 95% confidence interval 1.12 to 6.91), tobacco use (1.45%; adjusted odds ratio 3.04, 95% confidence interval 2.03 to 4.55), back pain (0.69%; adjusted odds ratio 1.74, 95% confidence interval 1.33 to 2.29), migraines (0.91%; adjusted odds ratio 2.14, 95% confidence interval 1.58 to 2

Iran has the second highest rate of cesarean section in the world. the corresponding rate in the third metropolitan city of Iran, Isfahan, is even higher. This paper aimed to assess correlates and determinants of intention for cesarean section versus normal vaginal delivery (NVD) among pregnant women in Isfahan. A study was conducted among 400 pregnant women aged 18-38 years, with gestational age of 24-40 weeks who attended labor clinics of nine hospitals in Isfahan during June and July 2014. Probability proportional to size was used to estimate the number of cases required to be selected for each hospital. T-test, chi-square and logistic regression analysis were employed to analyze the data. Mean age of women was 26.6±4.4 years. Multivariate analysis identified selected factors as determinants of intention for CS. These were "the role of physician" (OR=1.33, pcesarean section" and "individualism" influence CS decision through subjective norm. Choosing cesarean section voluntarily is a multifaceted decision which is shaped by various factors; hence, comprehensive interventions are suggested to discourage voluntary cesarean section. These interventions need to encompass changes in physicians' role, social norms, body image and correcting misperceptions among women towards CS and NVD during prenatal courses.

objective: To assess the effect of the scheduled gestational age for a repeat planned cesarean section (CS) on the risk for adverse pregnancy outcome in women with two or more previous CS. A retrospective cohort study of all women after ≥2 previous CS who were scheduled for a repeat planned CS. Women were divided into two groups at which the planned CS was scheduled: 38-week group or 39-week group. Overall, 377 were enrolled, 264 (70.0%) and 113 (30.0%) in the 38-week and the 39-week groups, respectively. The rate of an unplanned CS was significantly higher in the 39-week versus the 38-week group (23.0% versus 13.3%, p = 0.02). A repeat planned CS scheduled to week 39 was associated with an increased risk of maternal adverse outcome (31.9% versus 21.6%, p = 0.03). There was no significant difference in the rate of adverse neonatal outcome between the two groups (20.8% versus 23.0%, p = 0.5). The lowest rate of any adverse outcome (maternal and/or neonatal) was observed when CS was scheduled to 38 + 1 weeks of gestation. In women after two cesarean sections, scheduling a planned CS at around 39 weeks compared with at around 38 weeks is associated with an increased risk for maternal adverse outcome with no apparent advantage in terms of neonatal outcome.

To compare chlorhexidine with alcohol, povidone-iodine with alcohol, and both applied sequentially to estimate their relative effectiveness in prevention of surgical site infections after cesarean delivery. Women undergoing nonemergent cesarean birth at greater than 37 0/7 weeks of gestation were randomly allocated to one of three antiseptic skin preparations: povidone-iodine with alcohol, chlorhexidine with alcohol, or the sequential combination of both solutions. The primary outcome was surgical site infection reported within the first 30 days postpartum. Based on a surgical site infection rate of 12%, an anticipated 50% reduction for the combination group relative to either single skin preparation group, with a power of 0.90 and an α of 0.05, 430 women per group were needed to detect a difference. From January 2013 to July 2014, 1,404 women were randomly assigned to one of three groups: povidone-iodine with alcohol (n=463), chlorhexidine with alcohol (n=474), or both (n=467). The groups were similar with respect to demographics, medical disorders, indication for cesarean delivery, operative time, and blood loss. The overall rate of surgical site infection-4.3%-was lower than anticipated. The skin preparation groups had similar surgical site infection rates: povidone-iodine 4.6%, chlorhexidine with alcohol 4.5%, and sequential 3.9% (P=.85). The skin preparation techniques resulted in similar rates of surgical site infections. Our study provides no support for any particular method of skin preparation before cesarean delivery.

Maternal short stature has been observed to increase the risk of preterm birth; however, the aetiology behind this phenomenon is unknown. We investigated whether preeclampsia, an obstetric complication that often leads to preterm delivery and is reported to have an inverse association with women's height, mediates this association. We studied 218 412 women with no underlying diseases before pregnancy, who delivered singletons from 2005 to 2011 and were included in the Japan Society of Obstetrics and Gynecology perinatal database, which is a national multi-centre-based delivery database among tertiary hospitals. We assessed the risk of preterm delivery in relation to height using multivariate analysis, and how the association was mediated by risk of preeclampsia using mediation analysis. Each 5-cm decrement in height was associated with significantly higher risk of preterm delivery [relative risk 1.20; 95% confidence interval (CI): 1.13, 1.27] and shorter gestational age (-0.30; 95% CI: -0.44, -0.16 weeks). Mediation analysis showed that the effect of shorter height on increased risk of preterm delivery, due to an indirect effect mediated through increased risk of preeclampsia, was substantial for shorter gestational age (48%), as well as risk of preterm delivery (28%). When examining the three subtypes of preterm delivery separately, mediated effect was largest for provider-initiated preterm delivery without premature rupture of membranes (PROM) (34%), compared with spontaneous preterm delivery without PROM (17%) or preterm delivery with PROM (0%). Preeclampsia partially mediates the association between maternal short stature and preterm delivery.

To compare maternal outcomes after transection and after avoiding incision of the anterior placenta previa during cesarean delivery. In a retrospective study, records were reviewed for women who had anterior placenta previa and delivered by cesarean after 24 weeks of pregnancy at a tertiary center in Rouen, France. During period A (January 2000 to December 2006), the protocol was to systematically transect the placenta when it was unavoidable. During period B (January 2007 to December 2010), the technique was to avoid incision by circumventing the placenta and passing a hand around its margin. Logistic regression was used to identify independent risk factors associated with maternal transfusion of packed red blood cells. Eighty-four women were included (period A: n=43; period B: n=41). During period B, there was a reduction in frequency of intraoperative hemorrhage (>1000 mL) (P=0.02), intraoperative hemoglobin loss (P=0.005), and frequency of blood transfusion (P=0.02) as compared with period A. In multivariable analysis, period B was associated with a reduced risk of maternal transfusion (odds ratio 0.27; 95% confidence interval 0.09-0.82; P=0.02). Avoiding incision of the anterior placenta previa was found to reduce frequency of maternal blood transfusion during or after cesarean delivery.

OBJECTIVE To create a simple tool for predicting the likelihood of successful trial of labor after cesarean delivery (TOLAC) during the pregnancy after a primary cesarean delivery using variables available at the time of admission. METHODS Data for all deliveries at 14 regional hospitals over an 8-year period were reviewed. Women with one cesarean delivery and one subsequent delivery were included. Variables associated with successful VBAC were identified using multivariable logistic regression. Points were assigned to these characteristics, with weighting based on the coefficients in the regression model to calculate an integer VBAC score. The VBAC score was correlated with TOLAC success rate and was externally validated in an independent cohort using a logistic regression model. RESULTS A total of 5,445 women met inclusion criteria. Of those women, 1,170 (21.5%) underwent TOLAC. Of the women who underwent trial of labor, 938 (80%) had a successful VBAC. AVBAC score was generated based on the Bishop score (cervical examination) at the time of admission, with points added for history of vaginal birth, age younger than 35 years, absence of recurrent indication, and body mass index less than 30. Women with a VBAC score less than 10 had a likelihood of TOLAC success less than 50%. Women with a VBAC score more than 16 had a TOLAC success rate more than 85%. The model performed well in an independent cohort with an area under the curve of 0.80 (95% confidence interval 0.76–0.84). CONCLUSIONS Prediction of TOLAC success at the time of admission is highly dependent on the initial cervical examination. This simple VBAC score can be utilized when counseling women considering TOLAC. PMID:23921867

Given the continued rise in cesarean birth rate and the increased risk of surgical site infections after cesarean birth compared with vaginal birth, effective interventions must be established for prevention of surgical site infections. Prophylactic intravenous (IV) antibiotic administration 60 minutes prior to skin incision is recommended for abdominal gynecologic surgery; however, administration of prophylactic antibiotics has traditionally been withheld until after neonatal umbilical cord clamping during cesarean delivery due to the concern for potential transfer of antibiotics to the neonate. To compare the effects of cesarean antibiotic prophylaxis administered preoperatively versus after neonatal cord clamp on postoperative infectious complications for both the mother and the neonate. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 March 2014) and reference lists of retrieved papers. Randomized controlled trials (RCTs) comparing maternal and neonatal outcomes following prophylactic antibiotics administered prior to skin incision versus after neonatal cord clamping during cesarean delivery. Cluster-RCTs were eligible for inclusion but none were identified. Quasi-RCT and trials using a cross-over design were not eligible for inclusion in this review. Studies published in abstract form only were eligible for inclusion if sufficient information was available in the report. At least two review authors independently assessed the studies for inclusion, assessed risk of bias, abstracted data and checked entries for accuracy. We assessed the quality of evidence using the GRADE approach. We included 10 studies (12 trial reports) from which 5041 women contributed data for the primary outcome. The overall risk of bias was low.When comparing prophylactic intravenous (IV) antibiotic administration in women undergoing cesarean delivery, there was a reduction in composite maternal infectious morbidity (risk ratio (RR) 0.57, 95% confidence

Klippel-Trenaunay syndrome is a rare congenital vascular disease characterized by cutaneous hemangiomas, varicosities, and limb asymmetry, which may evolve with coagulation disorders and hemorrhage as more frequent complications in pregnant patients. Pregnancy is not advised in women with this syndrome due to increased obstetric risk. Female patient, 29 years old, 99kg, 167cm, BMI 35.4kg.m -2 , physical status ASA III, with 27 weeks of gestational age and diagnosis of Klippel-Trenaunay syndrome. She was admitted to attempt inhibition of preterm labor. As manifestations of Klippel-Trenaunay syndrome, the patient presented with cerebral and cutaneous hemangioma, mainly in the trunk and lumbar region, paresis in the left upper and lower limbs, and limb asymmetry, requiring the use of a walking stick. Physical examination revealed absence of airway vascular malformations and Mallampati class 3. Laboratory tests were normal and abdominal angiotomography showed irregular uterus, with multiple varices and vessels of arterial origin and bilateral periadnexal varices. She evolved with failure in preterm labor inhibition, and cesarean section under total intravenous anesthesia was indicated. Monitoring, central and peripheral venous access, radial artery catheterization, and diuresis were performed. Cesarean section was performed with median incision and longitudinal uterine body section for fetal extraction. Two episodes of arterial hypotension were seen intraoperatively. The postoperative evolution was uneventful. The choice of anesthesia was dependent on the clinical manifestations and the lack of imaging tests proving the absence of neuraxial hemangiomas.

To construct a hybrid model classification for cesarean section (CS) deliveries based on the woman-characteristics (Robson's classification with additional layers of indications for CS, keeping in view low-resource settings available in India). This is a cross-sectional study conducted at Nalanda Medical College, Patna. All the women delivered from January 2016 to May 2016 in the labor ward were included. Results obtained were compared with the values obtained for India, from secondary analysis of WHO multi-country survey (2010-2011) by Joshua Vogel and colleagues' study published in "The Lancet Global Health." The three classifications (indication-based, Robson's and hybrid model) applied for categorization of the cesarean deliveries from the same sample of data and a semiqualitative evaluations done, considering the main characteristics, strengths and weaknesses of each classification system. The total number of women delivered during study period was 1462, out of which CS deliveries were 471. Overall, CS rate calculated for NMCH, hospital in this specified period, was 32.21% ( p = 0.001). Hybrid model scored 23/23, and scores of Robson classification and indication-based classification were 21/23 and 10/23, respectively. Single-study centre and referral bias are the limitations of the study. Given the flexibility of the classifications, we constructed a hybrid model based on the woman-characteristics system with additional layers of other classification. Indication-based classification answers why, Robson classification answers on whom, while through our hybrid model we get to know why and on whom cesarean deliveries are being performed.

(1) To investigate Egyptian obstetricians' views towards cesarean delivery on maternal request, (2) to investigate Egyptian obstetricians' views towards some of the "potentially neglected" or controversial obstetrical skills or maneuvers as external cephalic version (ECV), fetal scalp pH measurement or tubal ligation during CS and (3) to examine the effect of professional level on the above factors. This is a descriptive study performed at the 8th annual Obstetrics and Gynecology conference of Suez Canal University held at Ismailia city in Egypt in June 2011 via a structured self administered questionnaire. Questionnaire was distributed to 223 conference attendants from the three professional levels (consultants, specialists and registrars) working at the two major institutions in Egypt: University and Ministry of Health. The structured questionnaire was based on informed opinion and professional guidelines. In total, 167 (75%) completed the questionnaire. Cesarean delivery on maternal request was accepted by 66% of the studied group and acceptance was significantly higher among consultants. There was no difference in all physicians' practices of cesarean section in both private and public settings. Limited access to medical equipment such as cardiotocogram (CTG) was shown in consultant group reflecting improper private sector preparations. The study revealed that 59% of obstetricians accepted vaginal breech delivery, and only 14% would consider ECV. Fetal scalp pH taking in cases of abnormal CTG was accepted by only 16.3% and 49% rejected the practice of instrumental delivery. There were significant differences among the three professional and the two institutional groups regarding these attitudes. There were different views regarding tubal sterilization during CS. Lack of knowledge, the need to improve some clinical skills and some professional attitudes may shed light on rising CS rates in Egypt.

To assess and compare the effectiveness and safety of single IV polus dose of carbetocin, versus IV oxytocin infusion in the prevention of PPH in obese nulliparous women undergoing emergency Cesarean Delivery. A double-blinded randomized-controlled trial was conducted on 180 pregnant women with BMI >30. Women were randomized to receive either oxytocin or carbetocin during C.S. The primary outcome measure was major primary PPH >1000 ml within 24 h of delivery as per the definition of PPH by the World Health Organization Secondary outcome measures were hemoglobin and hematocrit changes pre- and post-delivery, use of further ecobolics, uterine tone 2 and 12-h postpartum and adverse effects. A significant difference in the amount of estimated blood loss or the incidence of primary postpartum haemorrhage (>1000 ml) in both groups. Haemoglobin levels before and 24-h postpartum was similar. None from the carbetocin group versus 71.5% in oxytocin group needed additional utrotonics (p postpartum (p oxytocin infusion for maintaining adequate uterine tone and preventing postpartum bleeding in obese nulliparous women undergoing emergency cesarean delivery, both has similar safety profile and minor hemodynamic effect.

The purpose of this study was to determine whether surgical speed is associated with maternal outcomes in women who have a history of previous cesarean delivery (CD) and who require emergent delivery. This is a secondary analysis of a multicenter, prospective observational study of women with a history of previous CD. Women who attempted a vaginal birth after CD and required emergent CD were dichotomized into those with a skin incision-to-fetal delivery time of ≤2 min (I-D ≤2) or >2 min (I-D >2), based on the mode I-D. Rates of composite maternal complications and specific surgical complications were compared. Seven hundred ninety-three women had an emergency repeat CD: 108 women (13.6%) had I-D ≤2, and 685 women (86.4%) had I-D >2. The composite of maternal morbidity occurred in 36% of women with I-D≤2 and 23% with I-D>2 (P cesarean delivery, surgical speed was associated with an increased risk for maternal complications.

We describe the study design and patterns of participation for a cohort study of preterm delivery, focused on genital tract infections, nutrition, tobacco use, illicit drugs and psychosocial stress. Women are recruited at 24-29 weeks' gestation from prenatal clinics at a teaching hospital and a county health department. We recruited 57% of the first 1843 eligible women; 29% refused and 8% could not be contacted. White women were somewhat more likely to participate than African-American women (61% vs. 54% respectively). More notable differences were found comparing teaching hospital and health department clinics (71% vs. 47% participation respectively), with the health department clinic having a greater proportion refuse (24% vs. 33%) and more women who could not be contacted (4% vs. 11%). Participation was affected only minimally by day or timing of recruitment, but inability to contact diminished substantially as the study continued (13-0%). Refusals were largely unrelated to patient attributes. Lower education predicted inability to contact. Risk of preterm delivery was 14% among recruited women, 10% among women who refused, and 15% among women whom we were not able to contact, demonstrating that, overall, risk status was not lower among recruited women.
Full Text Available Spontaneous rupture of the renal collecting system is a rare but serious complication of pregnancy. We report a case of nontraumatic left renal calyceal rupture in a pregnancy which ultimately progressed to preterm delivery. A 29-year-old primigravida with a remote history of urolithiasis presented with left flank pain, suprapubic pain, and signs of preterm labor at 33 weeks of gestation. The patient was believed to have urolithiasis, although initial renal ultrasound failed to demonstrate definitive calculi. After a temporary improvement in flank pain with medication, the patient experienced acute worsening of her left flank pain. Urology was consulted and further imaging was obtained. Magnetic resonance imaging (MRI was consistent with bilateral hydronephrosis and rupture of the left renal calyx. Given the patient’s worsening pain in the setting of left calyceal rupture, the urology team planned for placement of a left ureteral stent. However, before the patient could receive her stent, she progressed to active labor and delivered a viable female infant vaginally. Following delivery, the patient’s flank pain resolved rapidly and spontaneously, so no surgical intervention was performed. A summary of the literature and the details of this specific clinical situation are provided.

Conclusion: The risk factors for preterm delivery identified in this study are consistent with previous studies. Clinicians and other health care providers should routinely assess women at high risk of preterm delivery during prenatal care to prevent the occurrence of preterm delivery and associated adverse perinatal outcomes.

Use of narcotic or "recreational" drugs has been associated with adverse pregnancy outcomes such as preterm delivery. However, the associations might be confounded by other factors related to high-risk behaviours. This is the first study to investigate the association between traditional opium use during pregnancy and risk of preterm delivery. We performed a population-based cohort study in the rural areas of the Golestan province, Iran between 2008 and 2010. We randomly selected 920 women who used (usually smoked) opium during pregnancy and 920 women who did not. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for the associations between the opium use during pregnancy and preterm delivery and adjustment was made for potential confounding factors. This study shows compared with non-use of opium and tobacco, use of only opium during pregnancy was associated with an increased risk of preterm delivery (OR = 1.56; 95% CI 1.05-2.32), and the risk was more than two-fold increased among dual users of opium and tobacco (OR = 2.31; 95% CI 1.37-3.90). We observed that opium use only was associated with a doubled risk for preterm caesarean delivery (OR = 2.05; 95% CI 1.10-3.82) but not for preterm vaginal delivery (OR = 1.25; 95% CI 0.75-2.07). Dual use of opium and tobacco was associated with a substantially increased risk of vaginal preterm delivery (OR = 2.58; 95% CI 1.41-4.71). Opium use during pregnancy among non-tobacco smokers is associated with an increased risk of preterm caesarean delivery, indicating an increased risk of a compromised foetus before or during labour. Women who use both opium and smoked during pregnancy have an increased risk of preterm vaginal delivery, indicating an increased risk of spontaneous preterm delivery.

To assess adverse events associated with radiofrequency endometrial ablation in treatment of heavy menstrual bleeding in patients with a history of low transverse cesarean delivery (C-section group) and patients who delivered vaginally (vaginal delivery group). Retrospective cohort study (Canadian Task Force classification II-2). Community-based gynecology practice in the United States. The study included 194 patients (100 in the C-section group and 94 in the vaginal delivery group), aged 21 to 55 years, with a history of heavy menstrual bleeding. NovaSure endometrial ablation procedures were performed from April 2004 through December 2010. Demographic characteristics, gynecologic and pregnancy history, and procedure setting were compared between groups. Intraoperative and postoperative adverse events that occurred within 72 hours of the procedure were summarized. The C-section and vaginal delivery groups were similar for demographic characteristics with the exception of age (mean [SD], 40.6 [5.0] years vs 42.5 [5.3] years, respectively; p = .01). Parity was significantly higher in the C-section group compared with the vaginal delivery group (2.4 [0.9] vs 2.1 [0.7]; p = .006). Adverse events commonly associated with endometrial ablation occurred in 3 patients in the C-section group and 5 patients in the vaginal delivery group (p = .68). In addition, 1 patient failed the pre-ablation cavity integrity assessment; therefore, ablation was not performed. All events resolved without sequelae. No uterine perforation or bowel or bladder injury occurred in any patient. Radiofrequency endometrial ablation performed in a community practice was well tolerated in patients with a history of low transverse cesarean delivery. Copyright © 2013 AAGL.

The aim of our study was to determine hospitalization rate for vaginal birth after cesarean section in Pikine, to evaluate the quality of the management of pregnant women with previous cesarean section and to determine prognostic factors of the outcome of a trial of scar. We conducted a retrospective study based on medical records and operational protocols of patients who underwent vaginal birth after cesarean section over the period 1 January 2010 - 31 December 2011. We analyzed socio-demographic data, pregnancy follow-up, therapeutic modalities and prognosis. Data were collected and analyzed using Microsoft Office Excel 2007 software and SPSS software 17.0. The frequency of vaginal births after cesarean section was 9.6%. The average age of our patients was 29.4 years. Primiparous women accounted for 54%. Short spacing interval between births was found in 52.6% of cases. Based on the number of cesarean sections, the breakdown was as follows: patients with a history of one previous cesarean section (79.8%), patients with a history of two previous caesarean sections (17.9%) and patients with a history of three previous caesarean sections (2.3%). The number of antenatal consultations performed was greater than or equal to 3 in 79.8% of cases. Patients undergoing evacuation accounted for 54.2% and they were already in labor at the time of admission in 81.7% of cases. Trial of scar was authorized in 177 patients (34.3%) and, at the end of this test, 147 patients (83%) had vaginal birth, of whom 21.7% by vacuum extraction. Cesarean section was performed in 71.4% of cases with 245 emergency cesarean sections and 93 scheduled cesarean sections. A history of vaginal birth was a determining factor in normal delivery (p = 0.0001). There was also a significant relationship between mode of admission and decision to perform a cesarean section (p = 0.0001). Maternal mortality was 0.4%. Perinatal mortality rate was 28.2‰ of live births. We are witnessing a dramatic increase of

A number of evidence-based interventions have been proposed to reduce post-cesarean delivery wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. We sought to estimate the impact of a group of evidence-based surgical measures (prophylactic antibiotics administered before skin incision, chlorhexidine-alcohol for skin antisepsis, closure of subcutaneous layer, and subcuticular skin closure with suture) on wound complications after cesarean delivery and to estimate residual risk factors for wound complications. We conducted a secondary analysis of data from a randomized controlled trial of chlorhexidine-alcohol vs iodine-alcohol for skin antisepsis at cesarean delivery from 2011-2015. The primary outcome for this analysis was a composite of wound complications that included surgical site infection, cellulitis, seroma, hematoma, and separation within 30 days. Risk of wound complications in women who received all 4 evidence-based measures (prophylactic antibiotics within 60 minutes of cesarean delivery and before skin incision, chlorhexidine-alcohol for skin antisepsis with 3 minutes of drying time before incision, closure of subcutaneous layer if ≥2 cm of depth, and subcuticular skin closure with suture) were compared with those women who did not. We performed logistic regression analysis limited to patients who received all the evidence-based measures to estimate residual risk factors for wound complications and surgical site infection. Of 1082 patients with follow-up data, 349 (32.3%) received all the evidence-based measures, and 733 (67.7%) did not. The risk of wound complications was significantly lower in patients who received all the evidence-based measures compared with those who

The aim of the study was to evaluate analgesic efficacy and tolerability of patient-controlled analgesia (PCA) with intravenous morphine. Our observational study included 50 women who underwent a Misgav-Ladach or modified Misgav-Ladach cesarean section. Automated PCA infusion device (Medima S-PCA Syringe Pump, Medima, Krakow, Poland) was used for postoperative pain control. Time of morphine administration or initiation of intravenous patient-controlled analgesia (IV PCA) with morphine was recorded, as well as post-operative pain at rest assessed by a visual analogue scale (VAS). All patients were followed up for 24 hours after discharge from the operating room, taking into account patient records, worst pain score at rest, number of IV PCA attempts, and drug consumption. Median of total morphine doses used during the postoperative period was 42.9mg (IQR 35.6-48.5), with median infusion time of 687.0 min. (IQR 531.0-757.5). Pain severity and total drug consumption improved after the first 3 hours following cesarean delivery (p PCA attempts per patient was 33 (IQR: 24-37), with median of 11 placebo attempts (IQR: 3-27). Patient-controlled analgesia with morphine is an efficient and acceptable analgesic method in women undergoing cesarean section.

Pelvic floor disorders affect women of all ages and are associated with significant economic burden and poor quality of life. Current literature suggests an association between childbirth and these disorders. In this review, we summarize recent advancements in our understanding of this association. Vaginal childbirth appears to be strongly associated with stress urinary incontinence and pelvic organ prolapse. There is less evidence to suggest an association between vaginal delivery and overactive bladder symptoms. History of more than one perineal laceration increases the likelihood of developing prolapse. Similar association has not been established for episiotomy. Disruption or denervation of structural components of pelvic floor support system, particularly levator ani muscle complex, is associated with later development of pelvic floor disorders. Imbalance in homeostasis of connective tissue remodeling of the vaginal wall from overstretching during childbirth is another possible mechanism. Pelvic floor disorders represent a significant health problem affecting women of all ages. Identification of potential modifiable risk factors and advancement in understanding of the underlying pathophysiology is crucial for primary and secondary prevention of these disorders and for improvement in treatment strategies.

Delivery by Cesarean section (CS) may predispose to allergic disorders, presumably due to alterations in the establishment of normal gut microbiota in early infancy. In this study, we sought to investigate the association between CS and physician-diagnosed food allergy and atopic dermatitis during the first 3 years of life, using data from a homogeneous, population-based, birth cohort. A total of 459 children born and cared for in the same tertiary maternity unit were examined at birth and followed up at 1, 6, 12, 18, 24, 30 and 36 months of age. Participants with symptoms suggestive of food allergy or atopic dermatitis were evaluated by a pediatric allergy specialist to confirm the diagnosis based on well-defined criteria. The rate of CS was 50.8% (n = 233). Food allergy was diagnosed in 24 participants (5.2%) while atopic dermatitis was diagnosed in 62 children (13.5%). Cesarean section (OR 3.15; 95% CI 1.14-8.70), atopic dermatitis of the child (OR 3.01; 95% CI 1.18-7.80), parental atopy (OR 4.33; 95% CI 1.73-12.1), and gestational age (OR 1.57; 95% CI 1.07-2.37) were significant and independent predictors of food allergy. Children with at least one allergic parent delivered by CS had higher probability of developing food allergy compared with vaginally delivered children of non-allergic parents (OR 10.0; 95% CI 3.06-32.7). Conversely, the effect of CS on atopic dermatitis was not significant (OR 1.35; 95% CI 0.74-2.47). Delivery by CS predisposes to the development of food allergy but not atopic dermatitis in early childhood. Cesarean section delivery seems to upregulate the immune response to food allergens, especially in children with allergic predisposition. © 2016 John Wiley & Sons A/S.

During cesarean delivery in patients with placenta previa, hemorrhaging after removal of the placenta is often challenging. In this condition, the extraordinarily high concentration of tissue factor at the placenta site may constitute a principle of treatment as it activates coagulation very effectively. The presumption, however, is that tissue factor is bound to activated factor VII. We hypothesized that topical application of recombinant activated factor VII at the placenta site reduces bleeding without affecting intravascular coagulation. We included 5 cases with planned cesarean delivery for placenta previa. After removal of the placenta, the surgeon applied a swab soaked in recombinant activated factor VII containing saline (1 mg in 246 mL) to the placenta site for 2 minutes; this treatment was repeated once if the bleeding did not decrease sufficiently. We documented the treatment on video recordings and measured blood loss. Furthermore, we determined hemoglobin concentration, platelet count, international normalized ratio, activated partial thrombin time, fibrinogen (functional), factor VII:clot, and thrombin generation in peripheral blood prior to and 15 minutes after removal of the placenta. We also tested these blood coagulation variables in 5 women with cesarean delivery planned for other reasons. Mann-Whitney test was used for unpaired data. In all 5 cases, the uterotomy was closed under practically dry conditions and the median blood loss was 490 (range 300-800) mL. There were no adverse effects of recombinant activated factor VII and we did not measure factor VII to enter the circulation. Neither did we observe changes in thrombin generation, fibrinogen, activated partial thrombin time, international normalized ratio, and platelet count in the peripheral circulation (all P values >.20). This study indicates that in patients with placenta previa, topical recombinant activated factor VII may diminish bleeding from the placenta site without initiation

Endometritis is a postpartum complication that is more common after cesarean delivery. It frequently requires intravenous antibiotic administration, prolonged hospital stays, and carries a risk of sepsis or abscess formation. Precesarean vaginal preparation has been shown to decrease the risk of endometritis in patients who have labored or have ruptured membranes. The objective of this study was to assess the practical implementation of a protocol for vaginal cleansing prior to cesarean delivery and the subsequent effect on endometritis rates in a clinical setting. This is a before-after retrospective cohort study evaluating the first 6 months of implementation of a vaginal cleansing protocol at a single institution. The primary outcome was the rate of implementation. Secondary outcomes included endometritis and other postoperative complications. The rate of implementation after 6 months was 68.3% (p < .001) and postoperative endometritis rates decreased from 14.0% before implementation to 11.7% after implementation (p .49, OR 0.77, CI 0.36-1.62). Postoperative fever decreased from 22.3% to 18.3% (p .256, OR 0.70, CI 0.37-1.30) and infectious wound complications were 4.5% and 5.8%, respectively (p .76, OR 1.07, CI 0.69-3.64). Implementation of a protocol for vaginal cleansing prior to cesarean delivery in women with ruptured membranes or in labor has high uptake, but in almost a third of eligible women it was not performed. The implementation, has led to a clinical, although not statistical, decrease in postoperative endometritis. Continued research is needed to explore how to improve uptake of this quality improvement measure.

Importance The rate of obesity among US women has been increasing, and obesity is associated with increased risk of surgical site infection (SSI) following cesarean delivery. The optimal perioperative antibiotic prophylactic regimen in this high-risk population undergoing cesarean delivery is unknown. Objective To determine rates of SSI among obese women who receive prophylactic oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery. Design, Setting, and Participants Randomized, double-blind clinical trial comparing oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery for the prevention of SSI in obese women (prepregnancy BMI ≥30) who had received standard intravenous preoperative cephalosporin prophylaxis. Randomization was stratified by intact vs rupture of membranes prior to delivery. The study was conducted at the University of Cincinnati Medical Center, Cincinnati, Ohio, an academic and urban setting, between October 2010 and December 2015, with final follow-up through February 2016. Interventions Participants were randomly assigned to receive oral cephalexin, 500 mg, and metronidazole, 500 mg (n = 202 participants), vs identical-appearing placebo (n = 201 participants) every 8 hours for a total of 48 hours following cesarean delivery. Main Outcomes and Measures The primary outcome was SSI, defined as any superficial incisional, deep incisional, or organ/space infections within 30 days after cesarean delivery. Results Among 403 randomized participants who were included (mean age, 28 [SD, 6] years; mean BMI, 39.7 [SD, 7.8]), 382 (94.6%) completed the trial. The overall rate of SSI was 10.9% (95% CI, 7.9%-14.0%). Surgical site infection was diagnosed in 13 women (6.4%) in the cephalexin-metronidazole group vs 31 women (15.4%) in the placebo group (difference, 9.0% [95% CI, 2.9%-15.0%]; relative risk, 0.41 [95% CI, 0.22-0.77]; P = .01). There were no serious adverse events, including

The current recommendation is to delay elective repeat cesarean deliveries (ERCD) until 39 weeks to decrease prematurity risks. Prior reports suggest accelerated maturity of fetuses according to race (African-Americans and Asians). To analyze the effect of the Hispanic ethnicity on the prematurity risk after ERCD. The US Natality Database from 2004 to 2008 was reviewed. Inclusion criteria were singleton delivery, no trial of labor, repeat cesarean. Exclusion criteria were fetal anomalies, history of diabetes/hypertension related disorders. Outcomes analyzed were Apgar score, assisted ventilation, intensive care admission, surfactant/antibiotic use and seizures. Two groups were identified: non-Hispanic Whites (NHW) and Hispanic Whites (HW). Regression analysis was performed to calculate adjusted odds ratios. Deliveries at 36-40 weeks were studied with 40 weeks as the reference group. A total of 930421 ERCDs were identified, 396823 NHW and 236733 HW. For NHW, the risk of prematurity was lower at 39 weeks. For HW, there was no difference in the risks of prematurity at/beyond 38 weeks. There appears to be accelerated maturity with no increase in prematurity risk at 38 weeks in HW delivered by ERCD. Ethnicity can be considered for patient counseling and decision making regarding optimal timing of elective interventions.

Although the option for vaginal delivery is most physiological, the achievement of cesarean section is very common in Brazil. The neonate cry represents the beginning of both processes, physiological adaptation and human vocal communication. The cry emission depends on the functioning of respiratory and laryngeal muscles, which are controlled by the nervous system. The acoustic analysis of neonate cry is useful in the assessment of healthy babies and can be used to characterize the signals of diseases through a previously multidisciplinary diagnosis, with immediate medical intervention. The present study compared the acoustic cry characteristics of 30 healthy newborn after a cesarean section and 30 healthy newborn after a vaginal delivery, of both genders, from the exact moment of birth until the first 5 min of life. Using the softwares VOXMETRIA and GRAM, it was possible to analyze the duration, frequency, intensity, occurrence, localization and inspiratory phonation, besides the type of spectrographic tracings. The acoustic cry characteristics of newborns after a C section and a vaginal delivery could evidence not only harmonic, expiratory, acute and strong emissions, but also emissions rich in sounds and varied in types of melody. The differences found can be related to the physiology of birth.

The management of pregnant patients with traumatic brain injury is challenging. A multidisciplinary team approach is mandatory, and management should be individualized according to the type and extent of injury, maternal status, gestational age, and fetal status. We report a 27-year-old term primigravida presenting after head injury with Glasgow coma scale score 11 and anisocoria. Depressed temporal bone fracture and acute epidural hematoma were diagnosed, necessitating an urgent neurosurgery. Her fetus was viable with no signs of distress and no detected placental abnormalities. Cesarean delivery was performed followed by craniotomy in the same setting under general anesthesia with good outcome of the patient and her baby. PMID:25829914
Full Text Available Cesarean delivery has increased significantly during the last decades. This study aimed to investigate the association between planned mode of delivery and method of feeding.A cohort was created retrospectively using data from a population-based maternal and child health surveillance system, which covers 27 study sites in China from 1993 to 2006. The cohort consisted of 431,704 women for analysis, including 22,462 women with planned cesarean delivery on maternal request (CDMR and 409,242 women with planned vaginal delivery (VD. Logistic regression models were used to examine the association between mode of delivery and method of feeding adjusting for selected covariates. In this cohort, 398,176 (92.2% women exclusively breastfed their baby, 28,798 (6.7% women chose mixed feeding, and 4,730 (1.1% women chose formula feeding before hospital discharge. Women who planned CDMR were less likely to exclusively breastfeed and more likely to formula feed their babies than those who planned VD. After adjusting for covariates, the odds ratios were 0.85 (95% CI: 0.81-0.89 for exclusive breastfeeding and 1.61 (95% CI: 1.45-1.79 for formula feeding. Associations between planned mode of delivery and method of feeding in the south, north, rural and urban areas yielded similar results.This study demonstrated that planned CDMR was associated with a lower rate of exclusive breastfeeding and a higher rate of formula feeding in a low-risk Chinese population.

Surgical site infection is one of the most common complications following Lower Segment Cesarean Section, which accounts for prolonged hospital stay thereby increasing expense. Prophylactic antibiotics in cesarean section reduces surgical site infection significantly. The best protection is provided when tissue level of antibiotics are adequate before incision, without prejudice to neonatal infectious morbidity. The objective of this study was to compare the incidence of surgical site wound infection with prophylactic antibiotics given before skin incision and after cord clamping following delivery of baby. This was a prospective, hospital based study, in which hundred cases of cesarean deliveries who received antibiotics prophylaxis one hour before the skin incision were compared with another 100 cases where antibiotic was given after cord clamping following delivery of the baby. Surgical site infection occurred in 3% of women who received antibiotics prophylaxis before skin incision as compared to 6% in whom antibiotic was given after cord clamping. It was statistically not significant (p = 0.465).

Prelacteal feeds (ie, foods other than breast milk offered before the milk comes in) have been identified as a risk factor for shorter breastfeeding duration and neonatal mortality. This study aimed to test for socioeconomic inequities on the risk of milk-based prelacteal feeding associated with cesarean section delivery. We conducted secondary cross-sectional data analyses of 7 Demographic and Health Surveys conducted in Latin American and Caribbean countries between 2005 and 2010 (N = 49 253 women with children younger than 3 years of age). Multivariate logistic regression was used to test the association between cesarean section delivery and the risk of milk-based prelacteal feeding in the total samples as well as within the lowest and highest wealth quintile subsamples by country and in the pooled sample. Almost one-third of newborns received milk-based (22.9%) prelacteal feeds. Prelacteal feeding prevalence varied from 17.6% in Guiana to 55% in Dominican Republic. Cesarean section delivery was associated with significantly higher odds of introduction of milk-based prelacteals in all countries (adjusted odds ratio [AOR] range, 2.34 in Bolivia to 4.50 in Peru). The association between cesarean section delivery and risk of milk-based prelacteal feeds was stronger among the poorest than wealthiest women (AOR [95% confidence interval], 2.94 [2.58-3.67] vs 2.17 [1.85-2.54]). Women of lower socioeconomic status may need additional breastfeeding support after cesarean section delivery to prevent the introduction of milk-based prelacteals. Reducing the rates of cesarean section deliveries is likely to reduce the prevalence of prelacteal feeding. © The Author(s) 2014.

A prospective cohort study was undertaken to evaluate the effect of pregnancy and childbirth in nulliparous pregnant women. The focus of this paper is on the difference in the prevalences and risk factors for lower urinary tract symptoms (LUTS) between woman who delivered vaginally or by cesarean and secondly the effect of LUTS on the quality of life between these two groups was analyzed. Included were 344 nulliparous pregnant women who completed four questionnaires with the Urogenital Distress Inventory and the Incontinence Impact Questionnaire (IIQ). Two groups were formed: vaginal delivery group (VD), which included spontaneous vaginal delivery and an instrumental vaginal delivery and cesarean delivery group (CD). No statistical significant differences were found in the prevalences of LUTS during pregnancy between the two groups. Three months after childbirth, urgency and urge urinary incontinence (UUI) are less prevalent in the CD group, but no statistical difference was found 1 year postpartum. Stress incontinence was significantly more prevalent in the VD group at 3 and 12 months postpartum. The presence of stress urinary incontinence (SUI) in early pregnancy is predictive for SUI both in the VD as in CD group. A woman who underwent a CD and had SUI in early pregnancy had an 18 times higher risk of having SUI in year postpartum. Women were more embarrassed by urinary frequency after a VD. After a CD, 9% experienced urge urinary incontinence. Urge incontinence affected the emotional functioning more after a cesarean, but the domain scores on the IIQ were low, indicating a minor restriction in lifestyle. In conclusion, after childbirth, SUI was significantly more prevalent in the group who delivered vaginally. Besides a vaginal delivery, we found both in the VD and in the CD group that the presence of SUI in early pregnancy increased the risk for SUI 1 year after childbirth. Further research is necessary to evaluate the effect of SUI in early pregnancy on SUI

To assess the sensitivity of birth certificates to preterm birth history and determine whether omissions are randomly or systemically biased. Subjects who experienced a preterm birth followed by a subsequent pregnancy were identified in a regional database. The variable "previous preterm birth" was abstracted from birth certificates of the subsequent pregnancy. Clinical characteristics were compared between subjects who were correctly versus incorrectly coded. 713 subjects were identified, of whom 65.5% were correctly coded in their subsequent pregnancy. Compared to correctly coded patients, patients who were not correctly identified tended to have late and non-recurrent preterm births or deliveries that were secondary to maternal or fetal indications. A recurrence of preterm birth in the subsequent pregnancy was also associated with correct coding. The overall sensitivity of birth certificates to preterm birth history is suboptimal. Omissions are not random, and are associated with obstetrical characteristics from both the current and prior deliveries. As a consequence, resulting associations may be flawed.

To compare the efficacy and safety of ketamine 0.25 mg/kg with ketamine 0.5 mg/kg to prevent shivering in patients undergoing Cesarean delivery. Prospective, randomized, double-blinded, placebo-controlled study. Operating rooms and postoperative recovery rooms. 120 ASA physical status 1 and 2 pregnant women scheduled for Cesarean delivery during spinal anesthesia. Patient characteristics, anesthetic and surgical details, Apgar scores at 1 and 5 minutes, and side effects of the study drugs were recorded. Heart rate, mean arterial pressure, oxygen saturation via pulse oximetry, tympanic temperature, severity of shivering, and degree of sedation were recorded before intrathecal injection and thereafter every 5 minutes. Patients were randomized to three groups: saline (Group C, n=30), intravenous (IV) ketamine 0.25 mg/kg (Group K-0.25, n=30), or IV ketamine 0.5 mg/kg (Group K-0.5, n=30). Grade 3 or 4 shivering was treated with IV meperidine 25 mg and the prophylaxis was regarded as ineffective. The number of shivering patients was significantly less in Group K-0.25 and in Group K-0.5 than in Group C (P = 0.001, P = 0.001, respectively). The tympanic temperature values of Group C were lower at all times of the study than in either ketamine group. Median sedation scores of Group K-0.5 were significantly higher than in Group K-0.25 or Group C at 10, 20, 30, and 40 minutes after spinal anesthesia. Prophylactic IV ketamine 0.25 mg/kg was as effective as IV ketamine 0.5 mg/kg in preventing shivering in patients undergoing Cesarean section during spinal anesthesia. Copyright © 2013 Elsevier Inc.

The Food and Drug Administration (FDA or we) is classifying the pressure wedge for the reduction of cesarean delivery into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the pressure wedge for the reduction of cesarean delivery's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.

Full Text Available Choosing the safest method of delivery and preventing preterm labour are obstetric challenges in reducing the number of preterm births and improving outcomes for mother and baby. Optimal route of delivery for preterm vertex neonates has been a controversial topic in the obstetric and neonatal community for decades and continues to be debated. We reviewed 22 studies, most of which have been published over the last five years with an aim to find answers to the clinical questions relevant to deciding the mode of delivery. Findings suggested that the neonatal outcome does not depend on the mode of delivery. Though Caesarean section rates are increasing for preterm births, it does not prevent neurodisability and cannot be recommended unless there are other obstetric indications to justify it. Therefore, clinical judgement of the obstetrician depending on the individual case still remains important in deciding the mode of delivery.

The present study aims to determine the efficiency and reliability of transcutaneous electrical nerve stimulation (TENS) in the management of pain related with uterine contractions after vaginal delivery and the pain related with both abdominal incision uterine contractions after cesarean section. A hundred healthy women who underwent cesarean section under general anesthesia were randomly assigned to the placebo group (Group 1) or the TENS group (Group 2), while 100 women who delivered by vaginal route without episiotomy were randomized into the placebo group (Group 3) or the TENS group (Group 4). The patients in Group 2 had statistically lower visual analog scale (VAS) and verbal numerical scale (VNS) scores than the patients in Group 1 (p TENS (p = 0.006). The need for analgesics at the eighth hour of vaginal delivery was statistically similar in the patients who were treated with TENS and the patients who received placebo (p = 0.830). TENS is an effective, reliable, practical and easily available modality of treatment for postpartum pain.

To demonstrate the safety of fetal delivery through placental incision in a placenta previa pregnancy. We examined the medical records of 80 women with singleton pregnancy diagnosed with placenta previa who underwent cesarean section between May 2010 and May 2015 at the Department of Obstetrics and Gynecology, Chungbuk National University Hospital. Among the women with placenta previa, those who did not have the placenta in the uterine incision site gave birth via conventional uterine incision, while those with anterior placenta previa or had placenta attached to the uterine incision site gave birth via uterine incision plus placental incision. We compared the postoperative hemoglobin level and duration of hospital stay for the mother and newborn of the two groups. There was no difference between the placental incision group and non-incision group in terms of preoperative and postoperative hemoglobin change, the amount of blood transfusions required by the mother, newborns with 1-min or 5-min Apgar scores below 7 points or showing signs of acidosis on umbilical cord blood gas analysis result of pH below 7.20. Moreover, neonatal hemoglobin levels did not differ between the two groups. Fetal delivery through placental incision during cesarean section for placenta previa pregnancy does not negatively influence the prognosis of the mother or the newborn, and therefore, is considered a safe surgical technique.
Full Text Available Uterine rupture is the primary concern when a patient chooses a trial of labor after a cesarean section. Bladder rupture accompanied by uterine rupture should be taken into consideration if gross hematuria occurs. We report the case of a patient with uterine rupture during a trial of labor after cesarean delivery. She had a normal course of labor and no classic signs of uterine rupture. However, gross hematuria was noted after repair of the episiotomy. The patient began to complain of progressive abdominal pain, gross hematuria and oliguria. Cystoscopy revealed a direct communication between the bladder and the uterus. When opening the bladder peritoneum, rupture sites over the anterior uterus and posterior wall of the bladder were noted. Following primary repair of both wounds, a Foley catheter was left in place for 12 days. The patient had achieved a full recovery by the 2-year follow-up examination. Bladder injury and uterine rupture can occur at any time during labor. Gross hematuria immediately after delivery is the most common presentation. Cystoscopy is a good tool to identify the severity of bladder injury.

To determine the optimum time for misoprostol administration to minimize blood loss during and after elective cesarean delivery. A randomized clinical trial was conducted at Mansoura University Hospital, Egypt, between January 1, 2013, and December 31, 2014. Eligible participants had full-term pregnancies, were scheduled to have a cesarean, and had normal fetal heart tracing. Patients were randomly allocated into two equal groups using computer-generated tables and sealed opaque envelopes. Misoprostol (400μg, given rectally) was given either before (group 1) or after (group 2) surgery. Patients, investigators, and data analysts were not masked to group assignment. The primary outcome was blood loss. A total of 348 women were included (174 in each group). Blood loss was significantly lower in group 1 than in group 2 (570±240 vs 844±270mL; Pcesarean delivery. The frequency of complications was not affected by time of administration. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

Full Text Available Objective: The aim of the study was to determine the effect of massage to the sacral region after cesarean delivery instead of employing a urinary catheter for the prevention of urinary retention. Study Design: Cross sectional study. Material and Methods: This interventional study population consisted of 60 women who were divided into two intervention groups and one control group. For the first intervention group, the sacral region was massaged every hour 10-15 minutes after cesarean delivery and every 30 minutes after a voiding sensation for the second intervention group. No interventions were made in the control group, although routine hospital services were provided. Socio-demographic data were collected using a questionnaire developed by the researchers. Other data were collected via observation. Results: Fifteen percent (15% of the women in the first intervention group needed to void 2 hours after cesarean delivery, 35% after 3 hours, and the mean time to void after delivery was 3.4±0.8 hours. Forty percent (40% of the women in the second intervention group needed to void after 5 hours, and the mean time to void after delivery was 5.5±0.8 hours. Sixty percent (60% of the women in the control group needed to void 6 hours later, and the mean time to void after delivery was 6.2±0.7 hours. Urinary retention was not observed in the first intervention group. Our statistical analysis showed a significant difference between the three groups in terms of mean times to void after cesarean delivery (p<0.05. Conclusion: In order to facilitate voiding and to prevent urinary retention, which is seen as a post-cesarean complication, massaging the sacral region could be recommended instead of urinary catheter insertion. Additional studies with larger groups are also recommended.

To determine the incidence of lower urinary tract (LUT) injury at the time of Cesarean delivery (CD) and to identify factors associated with LUT injury. Cases of LUT injury at delivery between 2001 and 2012, were identified by ICD-9 code. Chart review was utilized for verification and descriptive data collection. LUT injury incidence rates were calculated using annual delivery totals and trends over time were calculated using simple linear regression. LUT injury was classified as full-thickness bladder injury (including ureteral injury) or partial-thickness bladder injury based on degree of injury and post-operative intervention. Each case was year-matched to generate two CD controls. Logistic regression analysis was performed using maternal, delivery, and health system characteristics to identify factors associated with full or partial injury. Appropriate statistical analyses were performed with significance at p LUT injury did not vary significantly (p = 0.658). Of the 72 LUT injuries reported, 39 (54 %) were full-thickness bladder, 2 (3 %) ureteral, and 31 (43 %) were partial-thickness bladder injuries. Full injury, controlling for repeat CD, was associated with increasing maternal age, transfusion, and active second stage of labor. Partial injury, was associated with increasing maternal age and delivery in the first half of the academic year. Despite an increasing volume of CDs, LUT injury remained relatively uncommon (0.3 % of all CDs). Full and partial bladder injuries have unique risk profiles.

To evaluate the risk of emergency cesarean section according to the prepregnancy body mass index (BMI) and gestational weight gain per the 2009 Institute of Medicine guidelines. A retrospective analysis of data from 2,765 women with singleton full-term births (2009 to 2012) who attempted a vaginal delivery was conducted. Pregnancies with preeclampsia, chronic hypertension, diabetes, planned cesarean section, placenta previa, or cesarean section due to fetal anomalies or intrauterine growth restriction were excluded. Odds ratios (ORs) and confidence intervals (CIs) for emergency cesarean section were calculated after adjusting for prepregnancy BMI or gestational weight gain. Three-hundred and fifty nine (13.0%) women underwent emergency cesarean section. The adjusted OR for overweight, obese, and extremely obese women indicated a significantly increased risk of cesarean delivery. Gestational weight gain by Institute of Medicine guidelines was not associated with an increased risk of cesarean delivery. However, inadequate and excessive weight gain in obese women was highly associated with an increased risk of emergency cesarean section, compared to these in normal BMI (OR, 5.56; 95% CI, 1.36 to 22.72; OR, 3.63; 95% CI, 1.05 to 12.54; respectively), while there was no significant difference between normal BMI and obese women with adequate weight gain. Obese women should be provided special advice before and during pregnancy for controlling weight and careful consideration should be needed at the time of vaginal delivery to avoid emergency cesarean section.

To establish the safety and efficacy of misoprostol for second-trimester termination of pregnancy among women with one or more previous cesarean deliveries. In a retrospective study, data were reviewed from women attending a reproductive health clinic in Bloemfontein, South Africa, for second-trimester termination between 2010 and 2013. The study group, comprising women with one or more previous cesareans, was compared with a control group, comprising women with no previous cesarean or uterine scarring. Procedure-specific information was compared, including misoprostol use, termination duration, need for other methods (e.g. oxytocin), placenta delivery, termination outcome, and bleeding. The study group comprised 268 women: 231 (86.2%) with one and 37 (13.8%) with two previous cesareans. The control group comprised 266 women. Incomplete abortion was recorded in 223 (85.4%) of 261 women in the study group and 213 (80.4%) of 265 in the control group. The number of women with retained placenta was higher in the study than in the control group (158/261 [60.5%] vs 146/265 [55.1%]; PMisoprostol was safe for second-trimester termination among women with previous cesareans; however, the efficacy of the local regimen was reduced owing to high placental retention. © 2017 International Federation of Gynecology and Obstetrics.
To investigate the clinical significance and value in the prediction of preterm delivery of combined amniotic fluid IL-8 and Annexin A2 levels in preterm premature rupture of membranes (PPROM) and preterm labor (PTL). Sixty pregnant women at < 32 gestational weeks who developed PTL were divided into a PPROM group and a non-PPROM group. Ten normal pregnant women served as a control group. IL-8 and Annexin A2 levels were measured in amniotic fluid samples from each patient. Amniotic fluid IL-8 and Annexin-A2 levels in PTL (PPROM and non-PPROM groups) were significantly higher than those of the controls (p < 0.05). The PPROM group displayed higher amniotic fluid Annexin-A2 levels than did the non-PPROM group, with a statistically significant difference (p < 0.05). The PPROM group showed higher amniotic fluid IL-8 levels than did the non-PPROM group; however, this was statistically insignificant (p = 0.56). Combined detection of amniotic fluid IL-8 and Annexin-A2 in the prediction of preterm delivery within 2 weeks of measurement showed sensitivity of 81.25%, specificity of 88.89% and PPV of 92.86%. Amniotic fluid IL-8 and Annexin-A2 levels are associated with the occurrence of PPROM and PTL. Combined detection of IL-8 and Annexin-A2 levels in identifying preterm delivery within 2 weeks in PTL and PPROM is of possible clinical and predictive value.

To identify the risk factors for surgical site infection after cesarean delivery in a rural area in eastern Burkina Faso. A matched case-control study was conducted in Fada N'Gourma Regional Hospital Center and the Diapaga Medical Center with Surgical Antenna using data from 2011-2014. A total of 99 cases of surgical site infection after cesarean delivery were included in the study. Each case was matched with a control patient similar for age, admission date, and facility where the cesarean took place. Risk factors were identified using conditional logistic regression. Multivariate analysis identified hyperthermia at admission (OR 2.37; P=0.035), the presence of caput succedaneum in newborns (OR 7.07; P=0.001), and difficult delivery (OR 3.69; P=0. 019) as risk factors for surgical site infection. Provision of quality prenatal care, use of the partograph during labor, and the responsiveness of health workers during labor can reduce surgical site infection after cesarean delivery.

To examine whether an association exists between maternal dietary patterns and risk of preterm delivery. Prospective cohort study. Norway, between 2002 and 2008. 66 000 pregnant women (singletons, answered food frequency questionnaire, no missing information about parity or previously preterm delivery, pregnancy duration between 22+0 and 41+6 gestational weeks, no diabetes, first enrolment pregnancy). Hazard ratio for preterm delivery according to level of adherence to three distinct dietary patterns interpreted as "prudent" (for example, vegetables, fruits, oils, water as beverage, whole grain cereals, fibre rich bread), "Western" (salty and sweet snacks, white bread, desserts, processed meat products), and "traditional" (potatoes, fish). After adjustment for covariates, high scores on the "prudent" pattern were associated with significantly reduced risk of preterm delivery hazard ratio for the highest versus the lowest third (0.88, 95% confidence interval 0.80 to 0.97). The prudent pattern was also associated with a significantly lower risk of late and spontaneous preterm delivery. No independent association with preterm delivery was found for the "Western" pattern. The "traditional" pattern was associated with reduced risk of preterm delivery for the highest versus the lowest third (hazard ratio 0.91, 0.83 to 0.99). This study showed that women adhering to a "prudent" or a "traditional" dietary pattern during pregnancy were at lower risk of preterm delivery compared with other women. Although these findings cannot establish causality, they support dietary advice to pregnant women to eat a balanced diet including vegetables, fruit, whole grains, and fish and to drink water. Our results indicate that increasing the intake of foods associated with a prudent dietary pattern is more important than totally excluding processed food, fast food, junk food, and snacks.
Background: It has been recognized that preterm labor is related to short cervical length and that poor progress in labor is a major indication for cesarean section at term. We therefore hypothesize that long cervix is not associated with increased risk of cesarean delivery during labor at term. Objectives: The objective is to ...
Full Text Available Background: Opioid-induced side effects such as nausea and vomiting and pruritus are common and may be more debilitating than pain itself. We performed a study to assess the efficacy of dexamethasone in reducing postoperative nausea, vomiting, and pruritus in patients receiving neuraxial anesthesia with meperidine. Methods: Fifty-two women undergoing cesarean section were enrolled in the study. The control group and dexamethasone group received intravenously normal saline and dexamethasone, respectively, before spinal anesthesia. The occurrence of postoperative nausea, vomiting, and pruritus was assessed for 24 h in both groups. Results: The overall incidence of nausea and vomiting during the 24 h follow-up period was 37% and 22.2% for group saline and 20% and 12% for group dexamethasone, respectively (P=0.175, 0.469. The incidence of pruritus was not significantly different between the two groups. Pruritus severity was significantly less in the dexamethasone group than in the saline group (P=0.019. Conclusion: Prophylactic dexamethasone does not reduce the incidence of subarachnoid meperidine-induced nausea, vomiting, and pruritus in women undergoing cesarean delivery.

Background: Anxiety is a concern in obstetrics, especially in preeclamptic mothers. Sedation is not commonly used in parturients for fear of adverse neonatal effect. We investigated maternal and neonatal outcome of midazolam as an adjuvant to spinal anesthesia for elective cesarean delivery. Methods: A prospective randomized controlled trial, in which eighty preeclamptic parturients received either an intravenous dose of 0.035 mg/kg of midazolam or an equal volume of normal saline, 30 min before spinal anesthesia. Maternal anxiety was assessed using Amsterdam Preoperative Anxiety and Information Scale (APAIS); postoperative maternal satisfaction was assessed using Maternal Satisfaction Scale for Cesarean Section (MSSCS). Newborns were assessed using Apgar score, Neonatal Neurologic and Adaptive Capacity Score (NACS), and umbilical artery blood gases. Results: Mothers premedicated with midazolam showed a lower level of preoperative anxiety and a higher degree of postoperative satisfaction than the control group. There were no between-group differences regarding the neonatal outcome. Conclusion: Preeclamptic parturients premedicated with midazolam (0.035 mg/kg) before spinal anesthesia have lower anxiety and higher postoperative satisfaction levels, with no adverse effects on the newborns.

To evaluate whether measurement of the thickness of the fetal membranes by high-resolution ultrasound is a useful marker to predict preterm delivery. One hundred and fifty-eight women with singleton pregnancies at 18-35 gestational weeks were enrolled consecutively at our referral center for obstetric care and the thickness of their fetal membranes was measured using high-resolution ultrasound equipment. Data were analyzed to determine whether there were significant differences between those delivering at term and those delivering preterm. Receiver-operating characteristics (ROC) curves were used to determine the best cut-off point of membrane thickness for predicting preterm birth. Women who delivered preterm had greater fetal membrane thickness than did those who delivered at term (1.67 +/- 0.27 mm vs. 1.14 +/- 0.30 mm, P membrane thickness could be helpful in the prediction of preterm delivery.

Full Text Available Preterm delivery increases the risk of infant mortality and morbidity, and therefore developing reliable methods for predicting its likelihood are of great importance. Previous work using uterine electromyography (EMG recordings has shown that they may provide a promising and objective way for predicting risk of preterm delivery. However, to date attempts at utilizing computational approaches to achieve sufficient predictive confidence, in terms of area under the curve (AUC values, have not achieved the high discrimination accuracy that a clinical application requires. In our study, we propose a new analytical approach for assessing the risk of preterm delivery using EMG recordings which firstly employs Empirical Mode Decomposition (EMD to obtain their Intrinsic Mode Functions (IMF. Next, the entropy values of both instantaneous amplitude and instantaneous frequency of the first ten IMF components are computed in order to derive ratios of these two distinct components as features. Discrimination accuracy of this approach compared to those proposed previously was then calculated using six differently representative classifiers. Finally, three different electrode positions were analyzed for their prediction accuracy of preterm delivery in order to establish which uterine EMG recording location was optimal signal data. Overall, our results show a clear improvement in prediction accuracy of preterm delivery risk compared with previous approaches, achieving an impressive maximum AUC value of 0.986 when using signals from an electrode positioned below the navel. In sum, this provides a promising new method for analyzing uterine EMG signals to permit accurate clinical assessment of preterm delivery risk.

The aim of this study was to determine whether amniotic fluid levels of annexin A2, a phospholipid-binding protein that is abundant in amnion and regulates fibrin homeostasis, are associated with histological chorioamnionitis, preterm premature rupture of the membranes, and subsequent preterm delivery. Amniotic fluid was obtained from 55 pregnant women with preterm labor and/or preterm premature rupture of the membranes before 32weeks of gestation, and amniotic fluid levels of annexin A2 were measured with a sandwich enzyme-linked immunosorbent assay. Amniotic fluid levels of annexin A2 in patients with histological chorioamnionitis was higher than that in the remainder (P=0.053), whereas amniotic fluid levels of annexin A2 in patients with preterm premature rupture of the membranes was significantly higher than that in the remainder (P=0.002). Amniotic levels of annexin A2 was a fair test (area under receiver-operator characteristic curve=0.679), and amniotic fluid levels of annexin A2>878.2ng/mL had a sensitivity of 68.8%, a specificity of 65.2%, a positive predictive value of 73.3%, and a negative predictive value of 60.0% for predicting delivery within 2weeks after amniotic fluid sampling. Furthermore, the combined use of amniotic fluid cut-off levels of 878.2ng/mL for annexin A2 and 13.3ng/mL for interleukin-8 improved the specificity (91.3%) and the positive predictive value (89.5%). We identified amniotic fluid levels of annexin A2, especially in combination with amniotic fluid levels of interleukin-8, as a novel predictive marker for preterm delivery. © 2011 The Authors.

To identify the rate of surgical site infection (SSI) after Cesarean delivery (CD) and determine risk factors predictive for infection at a large academic institution. This was a retrospective cohort study in women undergoing CD during 2013. SSIs were defined by Centers for Disease Control (CDC) criteria. Chi square and t-tests were used for bivariate analysis and multivariate logistic regression was used to identify SSI risk factors. In 2419 patients, the rate of SSI was 5.5% (n = 133) with cellulitis in 4.9% (n = 118), deep incisional infection in 0.6% (n = 15) and intra-abdominal infection in 0.3% (n = 7). On multivariate analysis, SSI was higher among CD for labor arrest (OR 2.4; 95%CI 1.6-3.5; p infection control interventions.

Malaria is associated with high rates of morbidity and mortality worldwide, particularly in Africa, Southeast Asia and South America. Nonetheless, several cases of malaria have been reported in Western countries involving travelers from endemic areas, though very few involve pregnant women. In this article, we report a case of a young woman born in Sierra Leone who had been living in Italy for two years. She was admitted to our hospital with malaise; worsening of her condition led to Plasmodium falciparum infection diagnosis early during her hospital stay, as well as an urgent cesarean delivery. We briefly discuss the features of malaria in pregnancy, the difficulties associated with early diagnosis, and the possible fetal and maternal implications, and also consider how the disease may affect anesthetic management.
Full Text Available Unicornuate uterus with noncommunicating rudimentary horn occurs due to incomplete fusion of mullerian ducts. Pregnancy in this horn is a rare phenomenon usually resulting in rupture during second trimester of pregnancy. Prerupture diagnosis of pregnancy in rudimentary horn with ultrasonography is technically difficult, with sensitivity of 30%. We report a case of ruptured non-communicating rudimentary horn at 19 weeks in a woman with previous Cesarean delivery. She had a routine malformation scan in which diagnosis was missed. Later she presented to emergency in shock, with massive hemoperitoneum and ruptured horn. So a high index of suspicion is required to save this catastrophic event and associated maternal morbidity and mortality. In our opinion, routine excision of rudimentary horn should be undertaken during nonpregnant state laparoscopically. However, those women who refuse should be adequately counseled regarding potential complications and if pregnancy occurs in rudimentary horn, first trimester laparoscopic excision should be done.

There is an association between periodontal diseases and preterm delivery. To assess the relationship between periodontal diseases, ascending bacterial infection and placental pathology with preterm delivery. A periodontal examination and collection of amniotic fluid and subgingival plaque samples were performed in women with preterm labor with intact membranes, without an evident clinical cause or preterm premature rupture of membranes, without clinical chorioamnionitis or labor and a gestational age between 24 and 34 weeks. Microbial invasion of the amniotic cavity was defined as the presence of a positive amniotic fluid culture. Cervicovaginal infection was defined as a bacterial vaginosis or positive culture of cervix or vagina with a high neutrophil count. Ascending bacterial infection was diagnosed as the microbial invasion of the amniotic cavity by ascending bacteria or cervicovaginal infection. Corioamnionitis, funisitis or vellositis were diagnosed. Fifty-nine women were included: forty-two with preterm labor with intact membranes and seventeen with preterm premature rupture of membranes. The prevalence of periodontal diseases was 93.2%. Microbial invasion of the amniotic fluid was detected in 27.1% of patients. periodontal pathogenic bacteria were isolated in 18.6% of amniotic fluid samples and 71.2% of subgingival plaque samples. The prevalence of ascending bacterial infection was 83.1% and in 72.9% of women it was associated with periodontal disease. Preterm delivery (<37 weeks) occurred in 64.4% of patients and was significantly associated with generalized periodontal disease and with the association of ascending bacterial infection and periodontal diseases. Patients with preterm delivery and generalized periodontal disease had a higher frequency of chorioamnionitis and funisitis. Generalized periodontal disease and its association with ascending bacterial infection are related to preterm delivery and placental markers of bacterial ascending infection.
Full Text Available Background: The cesarean section (C-section has higher risk compared to normal vaginal delivery (NVD. The aim of this population-based study was to evaluate the frequency of mothers′ tendency toward the mode of delivery and the factors that can affect this inclination. Materials and Methods: This cross-sectional study was conducted from August 2011 to June 2012 in Fars Province, Iran, and comprised mothers in their 20 th to 30 th weeks of pregnancy. A questionnaire was designed to include, sociodemographic information, maternal knowledge, main sources of knowledge, attitude of the mother, husband, parents, close friends, and gynecologist, regarding the route of delivery, convenience factors, and barriers to choosing NVD, and mother′s preference for the route of delivery. Results: Of 6921 participants, 2197 (31.7% preferred C-section and 4308 (62.2% favored NVD while 416 (6% had no idea regarding the preferred route of delivery. Score of knowledge in 904 (13.1% participants was zero, and 1261 women (18.2% achieved an acceptable level of knowledge. Using binary logistic regression, positive history of previous abortion and/or infertility, higher education level of mother and husband, mother′s unacceptable level of knowledge regarding complications of C-section, and mother′s and husband′s positive attitude toward C-section were determinant factors in choosing C-section as a preferred route of delivery. Conclusion: Appropriate measures should be taken to raise awareness and knowledge of mothers and all families about complications of the C-section. Establishment of clinics for painless NVD and assuring mothers of benefits and lower complications of NVD can reduce the tendency for C-sections.

This study was aimed to evaluate the safety and efficacy of the second-trimester medical abortions using mifepristone and ethacridine lactate in women with placenta previa and/or prior cesarean deliveries. The patients who underwent a second-trimester pregnancy termination from January 2009 to December 2015 were retrospectively analyzed. The eligible patients were assigned to four groups based on placentation and cesarean history. The abortion interval (AI), blood loss, hospital stays, incidence of curettage, and transfusion were reviewed. Two women underwent cesarean sections for placenta increta. Finally, 443 patients were enrolled in this study, including 92 with placenta previa, 153 with prior cesarean deliveries, 36 with the both factors, and 236 with normal placentation and no cesarean delivery history. All the included cases had a successful vaginal delivery. There was no significant difference in AI, hospital stay, rate of hemorrhage, and transfusion among the four groups. Patients with prior cesarean section had higher blood loss than the normal group (P = 0.0017), as well as patients with both placenta previa and prior cesarean (P = 0.0018). However, there was no obvious blood loss in patients with placenta previa when compared with normal placetal patients (P = 0.23). No uterine rupture occurred in all patients. Mifepristone combined with ethacridine lactate is safe and effective for patients with low placentation or/and prior cesarean in the second-trimester pregnancy termination.

Background and Aims: This study was conducted to determine the effectiveness of intravenous (IV) granisetron in the prevention of hypotension and bradycardia during spinal anesthesia in cesarean delivery. Material and Methods: A total of 200 parturients scheduled for elective cesarean section were included in this study. They were randomly divided into two groups. Group I was given 1 mg granisetron diluted in 10 ml normal saline slowly IV, 5 min before spinal anesthesia. Group II was given 10 ml of normal saline, 5 min before spinal anesthesia. Mean arterial blood pressure and heart rate (HR) were recorded every 3 min until the end of surgery (for 45 min). The total consumption of vasopressors and atropine were recorded. Apgar scores at 1 and 5 min were also assessed. Results: Serial mean arterial blood pressure and HR values for 45 min after onset of spinal anesthesia were decreased significantly in group II, P cesarean section significantly reduces hypotension, bradycardia and vasopressors usage.

Full Text Available This research examines whether maternal optimism/pessimism is associated with unplanned Cesarean section deliveries in China. If so, does the association remain after controlling for clinical factors associated with C-sections? A sample of 227 mostly primiparous women in the third trimester of pregnancy was surveyed in a large tertiary care hospital in Beijing, China. Post-delivery data were collected from medical records. In bivariate analysis, both optimism and pessimism were related to unplanned c-section. However, when optimism and pessimism were entered into a regression model together, optimism was no longer statistically significant. Pessimism remained significant, even when adjusting for clinical factors such as previous abortion, previous miscarriage, pregnancy complications, infant gestational age, infant birthweight, labor duration, birth complications, and self-rated difficulty of the pregnancy. This research suggests that maternal mindset during pregnancy has a role in mode of delivery. However, more research is needed to elucidate potential causal pathways and test potential interventions.

Full Text Available OBJECTIVE: To assess the prevalence of urinary incontinence and associated vaginal squeeze pressure in primiparous women with and without previous gestational diabetes mellitus two years post-cesarean delivery. METHODS: Primiparous women who delivered by cesarean two years previously were interviewed about the delivery and the occurrence of incontinence. Incontinence was reported by the women and vaginal pressure evaluated by a Perina perineometer. Sixty-three women with gestational diabetes and 98 women without the disease were screened for incontinence and vaginal pressure. Multiple logistic regression models were used to evaluate the independent effects of gestational diabetes. RESULTS: The prevalence of gestational incontinence was higher among women with gestational diabetes during their pregnancies (50.8% vs. 31.6% and two years after a cesarean (44.8% vs. 18.4%. Decreased vaginal pressure was also significantly higher among women with gestational diabetes (53.9% vs. 37.8%. Maternal weight gain and newborn weight were risk factors for decreased vaginal pressure. Maternal age, gestational incontinence and decreased vaginal pressure were risk factors for incontinence two years after a cesarean. In a multivariate logistic model, gestational diabetes was an independent risk factor for gestational incontinence. CONCLUSIONS: The prevalence of incontinence and decreased vaginal pressure two years post-cesarean were elevated among women with gestational diabetes compared to women who were normoglycemic during pregnancy. We confirmed an association between gestational diabetes mellitus and a subsequent decrease of vaginal pressure two years post-cesarean. These results may warrant more comprehensive prospective and translational studies.

To investigate the independent impact of prepregnancy obesity on preterm delivery among women without chronic diseases by gestational age, preterm category and parity. A retrospective cohort study. Data from the Consortium on Safe Labor (CSL) in the USA (2002-08). Singleton deliveries at ≥23 weeks of gestation in the CSL (43 200 nulliparas and 63 129 multiparas) with a prepregnancy body mass index (BMI) ≥18.5 kg/m 2 and without chronic diseases. Association of prepregnancy BMI and the risk of preterm delivery was examined using Poisson regression with normal weight as reference. Preterm deliveries were categorised by gestational age (extremely, very, moderate to late) and category (spontaneous, indicated, no recorded indication). Relative risk of spontaneous preterm delivery was increased for extremely preterm among obese nulliparas (1.26, 95% CI: 0.94-1.70 for overweight; 1.88, 95% CI: 1.30-2.71 for obese class I; 1.99, 95% CI: 1.32-3.01 for obese class II/III) and decreased for moderate to late preterm delivery among overweight and obese multiparas (0.90, 95% CI: 0.83-0.97 for overweight; 0.87, 95% CI: 0.78-0.97 for obese class I; 0.79, 95% CI: 0.69-0.90 for obese class II/III). Indicated preterm delivery risk was increased with prepregnancy BMI in a dose-response manner for extremely preterm and moderate to late preterm among nulliparas, as it was for moderate to late preterm delivery among multiparas. Prepregnancy BMI was associated with increased risk of preterm delivery even in the absence of chronic diseases, but the association was heterogeneous by preterm categories, gestational age and parity. Obese nulliparas without chronic disease had higher risk for spontaneous delivery <28 weeks of gestation. © 2017 Royal College of Obstetricians and Gynaecologists.

Objective. In recent years, more and more delivery rooms have allowed husbands/partners to be present during a Cesarean section Nonetheless, many still oppose the idea. The study is designed to investigate the attitudes of Israeli gynecologists, anesthetists, operating-room nurses, and midwives on this issue. Design. The study's theoretical model comes from Fishbein and Ajzen's theory of reasoned action. A self-administered questionnaire was submitted to convenience sample. Subjects. 96 gynecologists, anesthetists, midwives, and operating-room nurses. Results. Significant differences were found between the occupational subgroups. Most of the findings supported the four hypotheses tested and confirmed earlier studies designed to verify the theoretical model. Conclusions. The main conclusion drawn is that delivery and operating-room staff need to be trained in the skills needed to promote the active participation of the baby's father in delivery and, if necessary, in a Cesarean section.

The rising cesarean birth rate has drawn attention to risks associated with repeat cesarean birth. Prevention of adhesions with adhesion barriers has been promoted as a way to decrease operative difficulty. However, robust data demonstrating effectiveness of such interventions are lacking. We report data from a multicenter trial designed to evaluate the short-term safety and effectiveness of a modified sodium hyaluronic acid (HA)-carboxymethylcellulose (CMC) absorbable adhesion barrier for reduction of adhesions following cesarean delivery. Patients who underwent primary or repeat cesarean delivery were included in this multicenter, single-blinded (patient), randomized controlled trial. Patients were randomized into either HA-CMC (N = 380) or no treatment (N = 373). No other modifications to their treatment were part of the protocol. Short-term safety data were collected following randomization. The location and density of adhesions (primary outcome) were assessed at their subsequent delivery using a validated tool, which can also be used to derive an adhesion score that ranges from 0-12. No differences in baseline characteristics, postoperative course, or incidence of complications between the groups following randomization were noted. Eighty patients from the HA-CMC group and 92 controls returned for subsequent deliveries. Adhesions in any location were reported in 75.6% of the HA-CMC group and 75.9% of the controls (P = .99). There was no significant difference in the median adhesion score; 2 (range 0-10) for the HA-CMC group vs 2 (range 0-8) for the control group (P = .65). One third of the HA-CMC patients met the definition for severe adhesions (adhesion score >4) compared to 15.5% in the control group (P = .052). There were no significant differences in the time from incision to delivery (P = .56). Uterine dehiscence in the next pregnancy was reported in 2 patients in HA-CMC group vs 1 in the control group (P = .60). Although we did not identify any short

Surgical site infections (SSIs) are an important cause of morbidity following cesarean delivery, particularly in obese patients. Methods to reduce SSIs after cesarean delivery would have an important impact in obese obstetric patients. The purpose of this study was to determine whether the Alexis O cesarean delivery retractor, a barrier self-retaining retractor, reduces SSIs and wound disruptions in obese patients undergoing cesarean delivery. This was a randomized controlled trial of obese women (body mass index ≥ 30 kg/m(2)) undergoing nonemergent cesarean delivery. Patients were randomized to the treatment group (using the Alexis O cesarean delivery retractor) or to the control group (using conventional handheld retractors). The primary outcome was SSI or wound disruption during the 30 day postoperative period. Secondary outcomes included operative time, estimated blood loss, change in hemoglobin, antiemetic use, length of postoperative hospital stay, hospital readmission, and other postoperative complications. A total of 301 patients were enrolled in the study. One hundred forty-four patients were randomized to the treatment group and 157 to the control group. Baseline characteristics and indications for cesarean delivery were similar between the 2 groups. Median body mass index was 40.1 kg/m(2). There were no significant differences between the treatment and the control group in the primary outcome of SSI or wound disruption rates at the 30 day assessment (20.6% vs 17.6%, P = .62), during the postoperative inpatient hospitalization or at the 1-2 week postoperative visit. There were also no differences in the primary outcome when adjusting for obesity class or thickness of the subcuticular layer. Patients in the treatment group had lower rates of uterine exteriorization (54.3% vs 87.3%, P cesarean delivery deliveries did not decrease SSI or wound disruption rates in an obese population. Its use as a retractor should be left to the discretion of the surgeon

OBJECTIVE: The aim of this study was to evaluate transvaginal sonographic assessment of cervical length at 23 weeks as a screening test for spontaneous preterm delivery in order to define a cut-off value that could be used to select twin pregnancies at low risk of spontaneous preterm delivery....... METHODS: In a prospective multicenter study of 383 twin pregnancies included before 14 + 6 weeks a cervical scan with measurement of the cervical length was performed at 23 weeks' gestation. The results were blinded for the clinicians if the cervical length was > or = 15 mm. The rates of spontaneous...... delivery at different cut-off levels of cervical length were determined. RESULTS: Eighty-nine percent of the twins had dichorionic placentation and 58% were conceived after assisted reproduction. The rate of spontaneous preterm delivery was 2.3% (1.5% for dichorionic (DC) and 9.1% for (MC) monochorionic...

An increase in Cesarean section birth rate is evident worldwide, especially in developed and developing countries. Since this trend is rapidly gaining epidemic status with unpredictable consequences regarding the reproductive and overall women's health, there is a need for systematic collection and analysis of Cesarean section occurrence data. At this moment, there is no standardized, internationally accepted classification that would be easy to understand and simple to apply. In 2001, Robson Cesarean section classification in ten groups, which might satisfy good classification criteria, was published. In this paper, we have retrospectively collected and sorted the data on Cesarean section births from the "Dr. Fra Mato Nikolić" Croatian Hospital in Nova Bila, according to Robson classification, for the period from January 1st, 1998 to December 31st, 2007. During this period, 6603 women have given birth. Of these, 1010 opted for Cesarean sec- tion (15.30%). The largest group of women giving birth belongs to group 3 (multiparous, single pregnancy, head down, 37 weeks gestation age or more, spontaneous labor), where 49.74% of all the analyzed births belong. The largest group for those with Cesarean sections is group 5 (previous Cesarean section) with 26.93% of all the Cesarean sections. Our results are similar to the results of studies done elsewhere in the world. Robson classification identifies the risk groups with high Cesarean section percentage and is appropriate for long-term tracking and international comparison of the recognized increase of the Cesarean section trend.

Preterm delivery is an important cause of perinatal morbidity and mortality, often precipitated by maternal infection or inflammation. Probiotic-containing foods, such as yogurt, may reduce systemic inflammatory responses. We sought to evaluate whether yogurt consumption during pregnancy is associated with decreased preterm delivery. We studied 965 women enrolled at midpregnancy into a clinical trial of prenatal docosahexaenoic acid supplementation in Mexico. Yogurt consumption during the previous 3 months was categorized as ≥5, 2-4, or Preterm delivery was defined as delivery of a live infant before 37 weeks gestation. We used logistic regression to evaluate the association between prenatal yogurt consumption and preterm delivery and examined interaction with maternal overweight status. In this population, 25.4%, 34.2%, and 40.4% of women reported consuming ≥5, 2-4, and preterm delivery was 8.9%. Differences in preterm delivery were non-significant across maternal yogurt consumption groups; compared with women reporting preterm delivery of 0.81 (95% confidence interval, CI [.46, 1.41]), and those reporting ≥5 cups of yogurt per week had aOR of 0.94 (95% CI [.51, 1.72]). The association between maternal yogurt consumption and preterm delivery differed significantly for nonoverweight women compared with overweight women (p for interaction = .01). Compared with nonoverweight women who consumed preterm delivery of 0.24 (95% CI [.07, .89]). Among overweight women, there was no significant association. In this population, there was no overall association between prenatal yogurt consumption and preterm delivery. However, there was significant interaction with maternal overweight status; among nonoverweight women, higher prenatal yogurt consumption was associated with reduced preterm delivery. © 2017 John Wiley & Sons Ltd.

This study compares the efficacy of sublingual misoprostol versus intravenous oxytocin in reducing bleeding during and after cesarean delivery. A randomized clinical trial conducted on 120 pregnant women at term (37-40 weeks) gestation scheduled for elective cesarean delivery, who were assigned to either sublingual misoprostol 400 μg or intravenous infusion of 20 units of oxytocin after delivery of the neonate. The main outcome measures were blood loss at and 2 hours after cesarean delivery, change in hematocrit value, need for any additional oxytocic drugs, and drug-related side effects. The overall mean blood loss was significantly lower in the misoprostol group compared to the oxytocin group (490.75 ± 159.90 mL vs. 601.08 ± 299.49 mL; p = 0.025). However, changes in hematocrit level (pre- and postpartum) was comparable between both groups. There was a need for additional oxytocic therapy in 16.7% and 23.3% after use of misoprostol and oxytocin, respectively (p = 0.361). Incidence of side effects such as shivering and metallic taste were significantly higher in the misoprostol group compared to the oxytocin group (p misoprostol is more effective than intravenous infusion of oxytocin in reducing blood loss during and after cesarean delivery. However, occurrence of temporary side effects such as shivering and metallic taste was more frequent with the use of misoprostol. Copyright © 2016. Published by Elsevier B.V.
Quality assurance in labor and delivery is needed. The method must be simple and consistent, and be of universal value. It needs to be clinically relevant, robust, and prospective, and must incorporate epidemiological variables. The 10-Group Classification System (TGCS) is a simple method providing a common starting point for further detailed analysis within which all perinatal events and outcomes can be measured and compared. The system is demonstrated in the present paper using data for 2013 from the National Maternity Hospital in Dublin, Ireland. Interpretation of the classification can be easily taught. The standard table can provide much insight into the philosophy of care in the population of women studied and also provide information on data quality. With standardization of audit of events and outcomes, any differences in either sizes of groups, events or outcomes can be explained only by poor data collection, significant epidemiological variables, or differences in practice. In April 2015, WHO proposed that the TGCS (also known as the Robson classification) is used as a global standard for assessing, monitoring, and comparing cesarean delivery rates within and between healthcare facilities.

To examine the risks of genital herpes and antiherpes treatment during pregnancy in relation to preterm delivery (PTD), we conducted a multicenter, member-based cohort study within 4 Kaiser Permanente regions: northern and southern California, Colorado, and Georgia. The study included 662,913 mother-newborn pairs from 1997 to 2010. Pregnant women were classified into 3 groups based on genital herpes diagnosis and treatment: genital herpes without treatment, genital herpes with antiherpes treatment, and no herpes diagnosis or treatment (unexposed controls). After controlling for potential confounders, we found that compared with being unexposed, having untreated genital herpes during first or second trimester was associated with more than double the risk of PTD (odds ratio (OR) = 2.23, 95% confidence interval (CI): 1.80, 2.76). The association was stronger for PTD due to premature rupture of membrane (OR = 3.57, 95% CI: 2.53, 5.06) and for early PTD (≤35 weeks gestation) (OR = 2.87, 95% CI: 2.22, 3.71). In contrast, undergoing antiherpes treatment during pregnancy was associated with a lower risk of PTD compared with not being treated, and the PTD risk was similar to that observed in the unexposed controls (OR = 1.11, 95% CI: 0.89, 1.38). The present study revealed increased risk of PTD associated with genital herpes infection if left untreated and a potential benefit of antiherpes medications in mitigating the effect of genital herpes infection on the risk of PTD. © The Author 2014.

Mode of birth affects development of the intestinal microbiota, and microbial dysbiosis has been associated with inflammatory bowel disease (IBD). We performed a population-based analysis to determine whether mode of delivery (cesarean section vs. vaginal delivery) affects risk of IBD. We collected data from the University of Manitoba IBD Epidemiology Database, which contains records on all Manitobans diagnosed with IBD from 1984 through 2010. Starting in 1970, 6-digit family health registration numbers were used in Manitoba to link mothers with their offspring. Maternal health records, including dates and modes of delivery and siblings of individuals with IBD, were identified. We obtained data on 1671 individuals with IBD and 10,488 controls (individuals without IBD, matched by age, sex, and area of residence at IBD diagnosis) linked to mothers' obstetrical records. Higher proportions of urban than rural residents were delivered by cesarean section for IBD cases (12.8% vs. 9.7%, P = .05) and controls (13.3% vs. 9.4%, P cesarean section (13.5% vs. 8.4%, P = .01). Overall, there was no difference in the percentage of IBD cases born by cesarean section (11.6%) vs. controls (11.7%, P = .93). In multivariate analysis, birth by cesarean section was not associated with an increased risk of subsequent IBD, controlling for age, sex, urban residence, and income (odds ratio, 1.04; 95% confidence interval, 0.89-1.23). Persons with IBD were no more likely to have been born by cesarean section than their siblings without IBD (1740 siblings from 1615 families) (11.6% vs. 11.3%; odds ratio, 1.14; 95% confidence interval, 0.72-1.80; P = .79). People with IBD were not more likely to have been born via cesarean section than controls or siblings without IBD. These findings indicate that events of the immediate postpartum period that shape the developing intestinal microbiome do not affect risk for IBD. Copyright © 2016 AGA Institute.

Background: Cesarean delivery conducted without medical indication places mothers and infants at risk for adverse outcomes. This study assessed changes in trends of, and factors associated with, cesarean deliveries in Jordan, from 2002 to 2012. Methods: Data for ever-married women ages 15–49 years from the 2002, 2007, and 2012 Jordan Population and Family Health Surveys were used. Analyses were restricted to mothers who responded to a question regarding the hospital-based mode of delivery for their last birth occurring within the 5 years preceding each survey (2002, N = 3,450; 2007, N = 6,307; 2012, N = 6,365). Normal birth weight infants and singleton births were used as markers for births that were potentially low risk for cesarean delivery, because low/high birth weight and multiple births are among the main obstetric variables that have been documented to increase risk of cesareans. Weighted descriptive and multivariate analyses were conducted using 4 logistic regression models: (1) among all mothers; and among mothers stratified (2) by place of delivery; (3) by birth weight of infants; and (4) by singleton vs. multiple births. Results: The cesarean delivery rate increased significantly over time, from 18.2% in 2002, to 20.1% in 2007, to 30.3% in 2012. Place of delivery, birth weight, and birth multiplicity were significantly associated with cesarean delivery after adjusting for confounding factors. Between 2002 and 2012, the rate increased by 99% in public hospitals vs. 70% in private hospitals; by 93% among normal birth weight infants vs. 73% among low/high birth weight infants; and by 92% among singleton births vs. 29% among multiple births. The changes were significant across all categories except among multiple births. Further stratification revealed that the cesarean delivery rate was 2.29 times higher in university teaching hospitals (UTHs) than in private hospitals (Pcesarean delivery rate among births that may have been at low risk for

To validate a prediction model for successful vaginal birth after Cesarean delivery (VBAC) based on sonographic assessment of the hysterotomy scar, in a Swedish population. Data were collected from a prospective cohort study. We recruited non-pregnant women aged 18-35 years who had undergone one previous low-transverse Cesarean delivery at ≥ 37 gestational weeks and had had no other uterine surgery. Participants who subsequently became pregnant underwent transvaginal ultrasound examination of the Cesarean hysterotomy scar at 11 + 0 to 13 + 6 and at 19 + 0 to 21 + 6 gestational weeks. Thickness of the myometrium at the thinnest part of the scar area was measured. After delivery, information on pregnancy outcome was retrieved from hospital records. Individual probabilities of successful VBAC were calculated using a previously published model. Predicted individual probabilities were divided into deciles. For each decile, observed VBAC rates were calculated. To assess the accuracy of the prediction model, receiver-operating characteristics curves were constructed and the areas under the curves (AUC) were calculated. Complete sonographic data were available for 120 women. Eighty (67%) women underwent trial of labor after Cesarean delivery (TOLAC) with VBAC occurring in 70 (88%) cases. The scar was visible in all 80 women at the first-trimester scan and in 54 (68%) women at the second-trimester scan. AUC was 0.44 (95% CI, 0.28-0.60) among all women who underwent TOLAC and 0.51 (95% CI, 0.32-0.71) among those with the scar visible sonographically at both ultrasound examinations. The prediction model demonstrated poor accuracy for prediction of successful VBAC in our Swedish population. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd. Copyright © 2017 ISUOG.

Cesarean delivery is the most common surgical procedure in low- and middle-income countries, so provision of anesthesia services can be measured in relation to it. This study aimed to assess the type of anesthesia used for cesarean delivery, the level of training of anesthesia providers, and to document the availability of essential anesthetic drugs and equipment in provincial, district, and mission hospitals in Zimbabwe. In this cross-sectional survey of 8 provincial, 21 district, and 13 mission hospitals, anesthetic providers were interviewed on site using a structured questionnaire adapted from standard instruments developed by the World Federation of Societies of Anaesthesiologists and the World Health Organization. The anesthetic workforce for the hospitals in this survey constituted 22% who were medical officers and 77% nurse anesthetists (NAs); 55% of NAs were recognized independent anesthetic providers, while 26% were qualified as assistants to anesthetic providers and 19% had no formal training in anesthesia. The only specialist physician anesthetist was part time in a provincial hospital. Spinal anesthesia was the most commonly used method for cesarean delivery (81%) in the 3 months before interview, with 19% general anesthesia of which 4% was ketamine without airway intubation. The mean institutional cesarean delivery rate was 13.6% of live births, although 5 district hospitals were table tilt or wedge, and insufficient blood supplies. Postoperative analgesia management was reported inadequate. This study identified areas where anesthetic provision and care could be improved. Provincial hospitals, where district/mission hospitals refer difficult cases, did not have the higher level anesthesia expertise required to manage these cases. More intensive mentorship and supervision from senior clinicians is essential to address the shortcomings identified in this survey, such as the implementation of evidence-based safe practices, supply chain failures, high
Full Text Available Anterior mediastinal mass is a rare pathology that presents considerable anesthetic challenges due to cardiopulmonary compromise.

We aimed to investigate if labor onset before planned cesarean delivery (CD) affects the risk of neonatal admission, respiratory distress, or neonatal infectious morbidity. Our cohort included singleton term pregnant women with intended CD who delivered at Aarhus University Hospital from 1990 to 2012. Two groups of women were identified: women with intended CD performed before labor (nonlabor CD) and women with intended CD performed after spontaneous labor onset (labor-onset CD); in both groups there was no other maternal or fetal medical indication for an immediate CD or for early-term CD scheduling. Data were stratified in early-term (37-38 weeks) and full-term (39-40 weeks) deliveries. The main outcome measures were neonatal admission, respiratory distress and neonatal infectious morbidity. Among 103 919 live births, 5071 deliveries were nonlabor CDs and 731 were labor-onset CDs. Compared to nonlabor CD, labor-onset CD was associated with similar risks of neonatal admission and respiratory distress, both at early and full term, but with a two- to three-fold increased risk of newborn septicemia or antibiotic treatment at early term. Labor onset at early term was associated with a lower risk of maternal blood loss of more than 500 mL, but with a higher risk of postoperative antibiotic treatment and endometritis. Labor onset before planned CD was not associated with a decrease in neonatal respiratory morbidity, but may be associated with increased risks of neonatal infection. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

To evaluate direct puncture embolization of the internal iliac artery with hemostatic gelatin sponge particles to treat pernicious placenta previa coexisting with placenta accreta during cesarean delivery. A retrospective study was conducted of data from women with pernicious placenta previa and placenta accreta who underwent direct puncture embolization of the internal iliac artery during cesarean delivery at a center in China between September 1, 2013, and February 28, 2015. Information regarding surgical procedures, operative data, and outcomes during hospitalization were obtained from medical records. The procedure was successful in all 16 cases included. Mean operative time was 78 minutes (range 65-90) and mean estimated blood loss was 1550 mL (range 1000-2500). Complications such as fever, buttock pain, or acute limb ischemia were not observed. The procedure was performed after partial cystectomy for two patients with bladder invasion. Postoperative Doppler imaging indicated uterine recovery and normalized uterine blood flow in all patients. Direct puncture embolization of the internal iliac artery during cesarean delivery was a safe, effective, simple, and rapid method to control hemorrhage among women with pernicious placenta previa and placenta accreta.

This is a randomized, controlled trial evaluating SSI following either 30% or 80% fraction of inspired oxygen (FIO2) during and 2 hours after cesarean delivery. Anesthesia providers administered FIO2 via a high-flow oxygen blender. Subjects, surgeons, and wound evaluation teams were blinded. Serial wound evaluations were performed. Data were analyzed using logistic regression models, Fisher exact test, and t test. In all, 179 women were randomized, and 160 subjects were included in the analysis. There were 12/83 (14.5%) SSIs in the control group versus 10/77 (13.0%) in the investigational group (p = 0.82). Caucasian race, increased body mass index, and longer operative time were identified as significant risk factors for infection (p = 0.026, odds ratio 0.283; p = 0.05, odds ratio = 1.058; p = 0.037, odds ratio = 1.038, respectively). Perioperative oxygenation with 80% Fio2 is not effective in reducing SSI following cesarean delivery. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

To determine the effectiveness and cost of antibiotic chemoprophylaxis in reducing infectious morbidity in low-risk women undergoing elective cesarean delivery. A prospective randomized clinical trial was performed at a single tertiary care center in Jinan, China between November 2012 and December 2013. Women were randomized to receive either antibiotic prophylaxis or no antibiotics prior to elective cesarean delivery at term. The infectious morbidity (fever, surgical site infection - SSI, endometritis and urinary tract infection), routine blood tests and hospital costs were measured. Total of 414 women were enrolled into the study; and 202 women received antibiotic chemoprophylaxis and 212 women received no antibiotics. Demographic and clinical characteristics were similar between the two groups. Total of one case in the treatment group and four case in the non-treatment group developed endometritis, giving the postoperative infection rate of 1.2%, which was not statistically significant between the two groups (χ(2) = 1.679, p = 0.195). The secondary outcomes were also not different between the two groups, except the costs of hospitalization, which was significantly higher in the treatment group (p cesarean delivery at term, prophylactic antibiotics did not reduce the risk of postoperative infection, but significantly increased the cost of hospitalization.

To compare the effectiveness and safety of carbetocin, misoprostol, and oxytocin for the prevention of postpartum hemorrhage following cesarean deliveries. A double-blind randomized controlled trial enrolled patients with a singleton pregnancy scheduled for an elective cesarean delivery at a maternity hospital in Cairo, Egypt, between October 1, 2012 and June 30, 2013. Participants were randomized using a computer-generated sequence to receive treatment with carbetocin, misoprostol, or oxytocin. The primary outcome was the occurrence of uterine atony necessitating additional uterotonics. Per-protocol analyses were performed. Patients, investigators, and data analysts were masked to treatment assignments. The present study enrolled 263 patients; data were analyzed from 88 patients treated with carbetocin, 89 treated with misoprostol, and 86 women treated with oxytocin. Further uterotonics were needed for the treatment of 5 (6%) patients who were treated with carbetocin, 20 (22%) patients treated with misoprostol, and 11 (13%) patients treated with oxytocin. In the prevention of uterine atony, carbetocin was comparable with oxytocin (RR 0.41, 95%CI 0.14-1.25) and superior to misoprostol (RR 0.21, 95%CI 0.07-0.58). Additional uterotonics were needed less frequently by patients treated with carbetocin. Carbetocin was comparable to oxytocin and superior to misoprostol in the prevention of uterine atony following an elective cesarean delivery. ClinicalTrials.gov: NCT02053922.

Preterm birth is the leading cause of death for newborn infants, and lipopolysaccharide (LPS) is commonly used to induce preterm delivery in experimental animals. Pyrrolizidine alkaloids (PAs) are widespread and occur in foods, herbs, and other plants. This study was to investigate the synergistic effects of LPS and two representative PAs, retrorsine (RTS) and monocrotaline (MCT), on preterm delivery and fetal death. Pregnant Kunming mice were divided into seven groups: control, RTS, MCT, LPS, RTS+LPS and two MCT+LPS groups. Animals in PAs and PAs+LPS groups were dosed intragastrically with RTS (10mg/kg) or MCT (20 mg/kg or 60 mg/kg) from gestational day (GD) 9 to GD16; mice given LPS were injected intraperitoneally with 150 μg/kg on GD15.5. Latencies to delivery, numbers of pups live and dead at birth were recorded, and livers of live neonates were collected. The incidence of LPS-induced preterm birth was enhanced in dams pretreated with MCT, and combination of PAs and LPS increased fetal mortality from PAs. The enhancement of LPS-induced preterm delivery and fetal demise in animals exposed chronically to PAs and other substances found in foods and beverages consumed widely by humans merits further focused investigation.

The National Institute of Child Health and Human Development, American College of Obstetricians and Gynecologists, and Society for Maternal-Fetal Medicine have emphasized the need to promote vaginal delivery and have offered recommendations to safely prevent primary cesarean delivery. However, there has been limited discussion regarding management of intravenous fluids and other aspects of labor management that may influence mode of delivery. Therefore the aim of our study was to determine whether an intravenous fluid rate of 250 vs. 125 mL/h is associated with a difference in cesarean delivery rate. Searches were performed in MEDLINE, OVID, Scopus, ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, Embase, Web of Science, and the Cochrane Library for randomized controlled trials. We included all randomized controlled trials comparing intravenous fluid rates of 250 vs. 125 mL/h in nulliparous women in spontaneous labor at term with singleton pregnancies at ≥36 weeks. Studies were included regardless of the type of intravenous fluids used and regardless of whether oral intake was restricted during labor. Studies including multiparous women or women whose labor was induced were excluded. The primary outcome was the incidence of cesarean delivery. We planned to assess a subgroup analysis according to type of fluids used and according to restriction of oral fluid intake. Seven trials including 1215 nulliparous women in spontaneous labor at term were analyzed; 593 (48.8%) in the 250 mL/h group, and 622 (51.2%) in the 125 mL/h group. Five studies used lactated Ringer's solution, one used normal saline in dextrose water, and in one study it was unclear which intravenous fluid was used. Women who received intravenous fluids at 250 mL/h had a significantly lower incidence of cesarean delivery for any indication (12.5 vs. 18.1%; RR 0.70, 95% CI 0.53-0.92; seven studies, 1215 participants; I 2 = 0%) and for dystocia (4.9 vs. 7.7%; RR

Lactogenesis II describes the onset of copious milk secretion, and the success of lactogenesis II has been determined in women by measuring the changes in the composition of mammary secretion in the immediate postpartum period. Therefore, the aim of this study was to determine the success of lactogenesis II at day 5 postpartum in women expressing milk for their preterm infants (n = 22) by measuring the lactogenesis II markers (milk citrate, lactose, sodium and total protein) and comparing them with women breastfeeding full-term infants (n = 16). There were no significant differences between the means (+/- SD) of the lactogenesis II markers for preterm (4.3 +/- 0.7 mM; 147 +/- 10 mM; 12 +/- 6 mM; 14.0 +/- 1.5 g/l, respectively) and term (3.4 +/- 1.4 mM; 126 +/- 17 mM; 30 +/- 13 mM; 15.3 +/- 2.5 g/l, respectively) women. However, variation about the mean was greater in preterm women (coefficient of variation for citrate, 40%; lactose, 14%; sodium, 42%; and total protein, 17%) compared with term women (17%, 7%, 33%, and 10%, respectively). All lactogenesis II markers were within 3 SD from the means for the term women and thus these women were considered to have successfully initiated their lactation. Only 18% of preterm women had all four lactogenesis II markers within 3 SD from the mean for term women. The remaining 82% of preterm women had at least one of the markers of lactogenesis II at pre-initiation concentrations (36% had 1 marker, 32% had 2 markers, and 14% had 3 markers). Furthermore, these women had significantly lower 24-hr milk production than those preterm women that had all four markers within 3 SD from the mean of the term women. It was concluded that 82% of preterm women had a compromised initiation of lactation, and this was not uniform in all women.

Evidence indicates that nutrients and minerals might play an important role in preterm delivery (PTD). The aim of this study was to determine maternal nutritional status during second trimester of pregnancy and its association with preterm delivery (Food Frequency Questionnaire (FFQ) in pregnant women of 14 to 20 weeks gestational age. The participants were followed up until delivery. Dietary intake of women with preterm delivery was compared with women who had term delivery. The results show that 61.2% of women were primiparous and that the incidence of preterm delivery was 7%. Manganese dietary intake was significantly higher in mothers with preterm delivery than those with term delivery (P=.03). Manganese was the only micronutrient correlated with preterm delivery after adjustment for maternal characteristics during second trimesters of pregnancy (OR=1.12; P=.01). These results suggest that high maternal manganese dietary intake during the second trimester of pregnancy may be associated with the risk of preterm delivery in Iranian pregnant women.

This trial was designed to compare levonorgestrel intrauterine device (LNG-IUD) use at 1 year after delivery between women randomized to postplacental insertion at the time of cesarean delivery and delayed insertion 4-8 weeks after delivery. This randomized controlled trial was conducted at two urban medical centers. Eligible pregnant women with planned cesarean deliveries were randomized to immediate postplacental insertion during cesarean or delayed insertion after 4-8 weeks. We used intention-to-treat analysis for the primary outcome of LNG-IUD use 12 months after delivery. Forty-two women were randomized, 20 into the postplacental group and 22 in the delayed group. Although confirmed use of the LNG-IUD 12 months after delivery was higher in the postplacental group (60.0% vs. 40.9%, p=.35), this difference was not statistically significance. Expulsion was significantly more common in the postplacental group (20.0% vs. 0%, p=.04). There were significant differences between the two sites in baseline population characteristics, follow-up and expulsion. The trial did not answer the intended question as it was halted early due to slow enrollment. Our results show higher expulsion after postplacental insertion compared to delayed insertion but suggest similar IUD use at 12 months. Moreover, it provides valuable lessons regarding a randomized controlled trial of postplacental LNG-IUD placement due to the challenges of estimating effect size and the nature of the population who might benefit from immediate insertion. Postplacental insertion of an IUD may improve use of highly effective contraception during the postpartum period. While our results suggest higher expulsion after postplacental insertion compared to delayed insertion and similar IUD use at 12 months, our trial was insufficient to definitively test our hypothesis.

The association between fetal sex and outcome of pregnancy and labor has been well documented in western populations. However, no studies in Malaysia or other developing countries have examined the effect of fetal sex on such outcomes.The main objective of this study was to determine the influence of fetal sex on the outcome of labor at term in a cohort of Malaysian nulliparae.A retrospective observational study was designed using data from 4644 Malaysian nulliparae who gave birth consecutively to singleton male babies at Hospital Sultanah Aminah, Johor Bahru, after normal full-term pregnancies.The results of this study indicate that mothers giving birth to male infants have a greater risk of requiring cesarean delivery because male babies are heavier and have statistically significantly greater head circumference (P < .001). These findings concur with those obtained in western populations and suggest that the differences in outcome observed are biological, not dictated by race, ethnicity, or environmental conditions. Such information could help in the antenatal assessment of Malaysian patients and stimulate more comprehensive studies of the mechanisms involved in this sex-based difference in outcomes. Reasons for such differences are proposed.

Klippel-Feil syndrome is defined by congenital fusion of two or more cervical vertebrae and can be associated with abnormalities in multiple systems. Management poses challenges to the anesthesiologist, particularly in pregnancy. Cervical spine immobility and instability can make the management of the airway fraught with danger and vertebral column distortion may make neuraxial anesthesia unreliable. We present the management of a nulliparous patient with features consistent with Type I Klippel-Feil syndrome undergoing elective cesarean delivery. The patient had a potentially difficult airway and features consistent with an unstable cervical spine and severe thoracic and lumbar scoliosis. A combined spinal-epidural technique was used which initially provided satisfactory anesthesia, but ultimately proved inadequate despite use of the epidural component. Satisfactory anesthesia for surgery was eventually achieved with the addition of an intravenous remifentanil infusion. We review previous case reports discussing anesthetic management of parturients with Klippel-Feil syndrome, and describe the challenges encountered and lessons learned from management of this case.

This study aims to identify risk factors for cesarean delivery (CD) surgical site infection (SSI). study design: Retrospective analysis of 2,739 CDs performed at the University of Pittsburgh in 2011. CD SSIs were defined using National Healthcare Safety Network (NHSN) criteria. Chi-square test and t-test were used for bivariate analyses and multivariate logistic regression was used to identify SSI risk factors. Of 2,739 CDs, 178 (6.5%) were complicated by SSI. Patients with a SSI were more likely to have Medicaid, have resident physicians perform the CD, an American Society of Anesthesiologists (ASA) class of ≥ 3, chorioamnionitis, tobacco use, and labor before CD. In multivariable analysis, labor (odds ratio [OR], 2.35; 95% confidence interval [95% CI], 1.65-3.38), chorioamnionitis (OR, 2.24; 95% CI, 1.25-3.83), resident teaching service (OR, 2.15; 95% CI, 1.54-3.00), tobacco use (OR, 1.70; 95% CI, 1.04-2.70), ASA class ≥ 3 (OR, 1.61; 95% CI, 1.06-2.39), and CDs performed for nonreassuring fetal status (OR, 0.43; 95% CI, 0.26-0.67) were significantly associated with CD SSI. Multiple patient, provider, and procedure-specific risk factors contribute to CD SSI risk which may be targeted in infection-control efforts.

To evaluate the feasibility of using the Robson Ten Group Classification System (TGCS) for cesarean delivery (CD) indications at institutional level. Prospective clinical audits of women delivering by CD at Women's Health Hospital, Assiut, Egypt, were conducted in 2008 and 2011. The CD rates overall and in each Robson group were calculated, as was the contribution of each group to the overall CD rate. In addition, the CD indications in each group were analyzed. The CD rate was 32% (443/1357) in 2008 and 38% (626/1628) in 2011. The most common CD indication at both time intervals was a previous CD. Multiparas without uterine scar, a single cephalic term pregnancy, and spontaneous labor (Robson Group 3) comprised the largest group of women undergoing CD, followed by nulliparas with a single cephalic term pregnancy and spontaneous labor (Group 1), and multiparas with a scarred uterus and a single cephalic term pregnancy (Group 5). Group 5 was the largest contributor (30%) to the overall CD rate, followed by Groups 1 and 4 (10% each). The TGCS can be applied at institutional level. It helps in planning strategies for specific subgroups of women to reduce CD rates and improve outcomes. © 2013.

To examine the delivery indication (maternal or fetal) for patients with preterm preeclampsia and assess whether disease characteristics at presentation are predictive of delivery indication. We conducted a retrospective cohort study at a tertiary hospital in Melbourne, Australia (Mercy Hospital for Women). We assessed indication for delivery for participants presenting with preeclampsia from 23(+0) to 32(+6) weeks gestation. We compared baseline disease characteristics, disease features at delivery and postnatal outcomes between those delivered for maternal or fetal indications, or for both maternal and fetal indications. Two hundred sixty six participants presented with preterm preeclampsia and 108 were eligible for inclusion in our study. More participants were delivered for maternal indications at 65.7% compared to those requiring delivery on fetal grounds at 19.4% or for both indications at 14.8% (p preeclampsia were predominantly delivered due to maternal disease progression compared to fetal compromise.

Objective The addition of lipophilic opioids to local anesthetics for spinal anesthesia has become a widely used strategy for cesarean anesthesia. A meta-analysis to quantify the benefits and risks of combining sufentanil with bupivacaine for patients undergoing cesarean delivery was conducted. Methods A comprehensive literature search without language or date limitation was performed to identify clinical trials that compared the addition of sufentanil to bupivacaine with bupivacaine alone for spinal anesthesia in healthy parturients choosing cesarean delivery. The Q and I2 tests were used to assess heterogeneity of the data. Data from each trial were combined using relative ratios (RRs) for dichotomous data or weighted mean differences (WMDs) for continuous data and corresponding 95% confidence intervals (95% CIs) for each trial. Sensitivity analysis was conducted by removing one study a time to assess the quality and consistency of the results. Begg’s funnel plots and Egger’s linear regression test were used to detect any publication bias. Results This study included 9 trials containing 578 patients in the final meta-analysis. Sufentanil addition provided a better analgesia quality with less breakthrough pain during surgery than bupivacaine alone (RR = 0.10, 95% CI 0.06 to 0.18, P bupivacaine-alone group (WMD = −1.0 min, 95% CI −1.5 to −0.58, P Bupivacaine and sufentanil combination is superior to that of bupivacaine alone for spinal anesthesia for cesarean delivery in analgesia quality. Women receiving the combined two drugs had less breakthrough pain, shorter sensory block onset time, and longer first analgesic request time. However, the addition of sufentanil to bupivacaine increased the incidence of pruritus. PMID:27032092

However, data on its efficacy and safety in women with previous cesarean deliveries are limited.Case presentation: We report a 36-year-old patient, gravida 11 para 6, with a diagnosis of missed miscarriage at 15 weeks of gestation. The patient had a significant obstetric history of previous five cesarean deliveries and uterine rupture. Following patient counseling about the medical and surgical options of managing her miscarriage, the patient opted for medical method. Low-dose misoprostol of 100 µg was inserted vaginally and repeated again after 6 hours. The patient had an uneventful complete miscarriage following the second dose of misoprostol. No uterine rupture, no extra vaginal bleeding, and no blood transfusion were observed.Conclusion: We conclude that adopting a low-dose misoprostol protocol could be potentially safe and effective in managing second trimester missed miscarriage in women with repeated cesarean deliveries and/or uterine rupture history. Further studies are needed to confirm these results. Keywords: cesarean section, uterine rupture, prostaglandin E1, misoprostol, second trimester, miscarriage, abortion

To compare the expulsion rate of Nova-T380, Multiload 375, and Copper-T380A intrauterine contraceptive devices (IUCDs) inserted during cesarean delivery. A comparative randomized study was conducted between January 1, 2013, and June 30, 2014, in three maternity centers in Egypt and Saudi Arabia. All women scheduled for an elective cesarean and accepting intraoperative insertion of an IUCD were randomly allocated to receive the Nova-T380 (group 1), Multiload 375 (group 2), or Cu-T380A (group 3) using a computer-generated table. Researchers and participants were not masked to the type of IUCD. Follow-up was for 1 year. The primary outcome was IUCD expulsion (complete or partial [i.e. displacement]). Each group contained 40 participants. At 1 year, expulsion had been reported for 5 (13%) women in group 1, 2 (5%) in group 2, and 6 (15%) in group 3 (P>0.05 for all). The frequency of displacement was significantly lower in group 2 (5 [13%] participants) than in group 1 (15 [38%]; P=0.001) and group 3 (14 [35%]; P=0.008). Despite a comparable risk of expulsion following IUCD insertion during cesarean delivery, the Multiload 375 device showed the lowest risk of displacement.

Full Text Available Objectives. This study aims to analyze the cesarean section (CS rates and vaginal delivery rates in tertiary hospitals of China, explore the costs of two different deliveries, and examine the relative influencing factors of the costs in both CS and vaginal deliveries. Methods. 30,168 anonymized obstetric medical cases were selected from three sample tertiary hospitals in Chongqing Municipality from 2011 to 2013. Chi-square test was used to compare the distributions of CS and vaginal deliveries under different indicators. Mann–Whitney test and Kruskal-Wallis test were adopted to analyze the differences under different items. Multiple linear regression was used to determine the influencing factors of the costs of different delivery modes. Results. (1 The rates of CS were 69%, 65.5%, and 59.2% in the three sample tertiary hospitals in Chongqing from 2011 to 2013. (2 The costs and the length of stay of CS were greater than those of vaginal delivery, which had significant differences (P<0.005. (3 The areas, length of stay, age, medical insurance, and modes of delivery were the influencing factors of both CS and vaginal delivery costs. Discussion. The high CS rates in China must be paid significant attention. The indicators of two modes of delivery should be regulated strictly. CS rate reduction and saving medical resources will be the benefits if vaginal delivery is chosen by pregnant women.

Full Text Available OBJECTIVE: This study examined the ability of social, demographic, environmental and health-related factors to explain geographic variability in preterm delivery among black and white women in the US and whether these factors explain black-white disparities in preterm delivery. METHODS: We examined county-level prevalence of preterm delivery (20-31 or 32-36 weeks gestation among singletons born 1998-2002. We conducted multivariable linear regression analysis to estimate the association of selected variables with preterm delivery separately for each preterm/race-ethnicity group. RESULTS: The prevalence of preterm delivery varied two- to three-fold across U.S. counties, and the distributions were strikingly distinct for blacks and whites. Among births to blacks, regression models explained 46% of the variability in county-level risk of delivery at 20-31 weeks and 55% for delivery at 32-36 weeks (based on R-squared values. Respective percentages for whites were 67% and 71%. Models included socio-environmental/demographic and health-related variables and explained similar amounts of variability overall. CONCLUSIONS: Much of the geographic variability in preterm delivery in the US can be explained by socioeconomic, demographic and health-related characteristics of the population, but less so for blacks than whites.
implemented in conjunction with antenatal care models that promote women's empowerment as a strategy for reducing preterm delivery. The global community needs to support more discovery research on normal and abnormal pregnancies to facilitate the development of preventive interventions for universal application.

The relationships between breastfeeding discontinuation and cesarean section delivery, and the occurrence of postpartum depression (PPD) remain unclear. Therefore, we aimed to investigate the association of breastfeeding discontinuation and cesarean section delivery with PPD during the first 6 months after delivery. Data were extracted from the Korean National Health Insurance Service-National Sample Cohort for 81,447 women who delivered during 2004-2013. PPD status was determined using the diagnosis code at outpatient or inpatient visit during the 6-month postpartum period. Breastfeeding discontinuation and cesarean section delivery were identified from prescription of lactation suppression drugs and diagnosis, respectively. Cox proportional hazards models were used to calculate adjusted hazard ratios. Of the 81,447 women, 666 (0.82%) had PPD. PPD risk was higher in women who discontinued breastfeeding than in those who continued breastfeeding (hazard ratio=3.23, Pcesarean section delivery than in those with vaginal delivery (hazard ratio=1.26, P=0.0040), and in women with cesarean section delivery who discontinued breastfeeding than in those with vaginal delivery who continued breastfeeding (hazard ratio=4.92, Pcesarean section delivery were associated with PPD during the 6-month postpartum period. Our results support the implementation of breastfeeding promoting policies, and PPD screening and treatment programs during the early postpartum period. Copyright © 2017 Elsevier B.V.

Serum uric acid is a marker for oxidative stress in preeclampsia. Because oxidative stress can result in diminished uterine contractility and impaired vascular relaxation, we hypothesized that an elevated serum uric acid level in women undergoing neuraxial anesthesia for cesarean delivery would be associated with greater uterine atony, as measured by supplemental uterotonic agent use and blood loss, and less hypotension, as measured by total vasopressor use. All records of patients (n=2527) undergoing cesarean delivery in 2009 were reviewed. Serum uric acid was measured within 24h of delivery in 509 patients; data from 345 patients with singleton pregnancies undergoing neuraxial anesthesia were analyzed. Demographic data, medical and obstetric history, anesthetic management and peripartum course were evaluated. ANOVA, Chi-square, and multivariate logistic and linear regression analyses were performed. Increased serum uric acid correlated positively with preeclampsia and the need for supplemental uterotonic agents (odds ratio 1.53, 95%CI 1.2-2.0, P=0.002), but not blood loss. The presence of preeclampsia also correlated with greater supplemental uterotonic agent use (P=0.01). The correlation between serum uric acid and post-spinal vasopressor use (i.e., none, moderate, and high) was of borderline significance (P=0.05). In patients without diabetes, serum uric acid levels correlated inversely with post-spinal vasopressor use (P=0.04). Elevated serum uric acid in parturients undergoing cesarean delivery with neuraxial anesthesia correlated with increased use of supplemental uterotonic agents and decreased use of post-spinal vasopressors. Further validation of this study is required to determine if serum uric acid in parturients can serve as a reliable predictor for higher and lower occurrences of uterine atony and spinal-induced hypotension, respectively.

To determine the risk factors causing re-laparotomy and the indications, management and outcomes of re-laparotomy after a cesarean section. We had, during the study period of January 2002 to January 2007, 28,799 cesarean sections and 35 cases with re-laparotomy. We studied the patients' age, parity, indications for cesarean section and indications for re-laparotomy, time interval after cesarean section to reopening of the abdomen, type of surgery, need for blood transfusion and span of hospital stay. The incidence of re-laparotomy was 0.12%. Cases with placental abruption and previous cesarean > or =3 had a higher risk for re-laparotomy. Procedures that were performed at re-laparotomy were drainage and resuturing of hematomas (n = 8), resuturing of uterus and securing hemostasis with stitches (n = 10), bladder repair (n = 1), herniation repair (n = 1), total abdominal hysterectomy (n = 2), subtotal abdominal hysterectomy (n = 5), and draining and resuturing of broad ligament, parametrium, abdominal wound, and cutaneous and subcutaneous tissue due to infection and abscess formation (n = 8). Two cases required admission into the intensive care unit. We had one case with maternal mortality. Majority of the complications were revealed at an early period and these were hemorrhagic cases mostly. Although the rate of re-laparotomy after cesarean section is low, several actions must be undertaken to decrease the need for re-laparotomy. In particular, cases with placental abruption and previous cesarean > or =3 are with higher risk for re-laparotomy and have a 15-fold risk for re-laparotomy after cesarean section.

Studies have reported the association between lead exposure during pregnancy and preterm birth. However, findings are still inconsistent. This prospective birth cohort study evaluated the risks of preterm and early-term births and its association with prenatal lead exposure in Hubei, China. A total of 7299 pregnant women were selected from the Healthy Baby Cohort. Maternal urinary lead levels were measured by the Inductively Coupled Plasma Mass Spectrometry. The associations between tertiles of urinary lead levels and the risks of preterm and early-term deliveries were assessed using multiple logistic regression models. The geometric mean of creatinine-adjusted urinary lead concentrations among all participating mothers, preterm birth, and early-term birth were 3.19, 3.68, and 3.17μg/g creatinine, respectively. A significant increase in the risk of preterm births was associated with the highest urinary lead tertile after adjusting for confounders with odds ratio (OR) of 1.96. The association was more pronounced among 25-36 years old mothers with OR of 2.03. Though significant p trends were observed between lead exposure (medium and high tertiles) and the risk of early-term births, their ORs were not significant. Our findings indicate that the risk of preterm birth might increase with higher fetal lead exposure, particularly among women between the age of 25 and 36 years. Copyright © 2017 Elsevier GmbH.

The objective was to identify risk factors associated with blood transfusion in patients undergoing high-order Cesarean delivery (CD). This was a retrospective cohort study of patients undergoing third or more CD by a single maternal-fetal medicine practice between 2005 and 2016. We compared risk factors between women who did and did not receive a red blood cell transfusion during the operation or before discharge. Repeat analysis was performed after excluding women with placenta previa. A total of 514 patients were included, 18 of whom (3.5%; 95% confidence interval [CI], 2.2%-5.5%) received a blood transfusion. Placenta previa was the most significant risk factor for transfusion (61.1% of patients who received a transfusion vs. 1% of patients who did not; p blood transfusion. After women who had placenta previa were excluded, the incidence of blood transfusion was seven of 498 (1.4%; 95% CI, 0.7%-2.9%). Risk factors significantly associated with blood transfusion in the absence of previa were prophylactic anticoagulation during pregnancy and having labored. The incidence of transfusion in patients with no placenta previa, no anticoagulation, and no labor was 0.7% (95% CI, 0.3%-2.1%). Placenta previa was the most predictive risk factor for transfusion with a positive predictive value of 68.8% and a negative predictive value of 98.4%. In patients undergoing a third or more CD, only placenta previa, prophylactic anticoagulation during pregnancy, and having labored are independently associated with requiring a blood transfusion. These data can be used to guide physician ordering of prepared blood products preoperatively. © 2017 AABB.

Posture and baricity during induction of spinal anesthesia with intrathecal drugs are believed to be important in determining spread within the cerebrospinal fluid. In this double-blind prospective study, 150 patients undergoing elective cesarean delivery were randomized to receive a hyperbaric, isobaric, or hypobaric intrathecal solution of 10 mg bupivacaine during spinal anesthesia induced in either the sitting or right lateral position. After an intrathecal injection using a combined-spinal technique patients were placed in the supine wedged position. We determined the densities of the three intrathecal solutions from a previously validated formula and measured using a DMA-450 density meter. Data collection included sensory level, motor block, episodes of hypotension, and ephedrine use. Statistical analysis included analysis of variance and Cuzick's trend. In the lateral position, baricity had no effect on the spread of sensory levels for bupivacaine compared to the sitting position, where there was a statistically significant difference in spread with the hypobaric solution producing higher levels of analgesia than the hyperbaric solution (P = 0.002). However, the overall differences in maximal spread only differed by one dermatome, with the hyperbaric solution achieving a median maximum sensory level to T3 compared with T2 for the isobaric and hypobaric solutions. Motor block was significantly (P = 0.029) reduced with increasing baricity and this trend was significant (P = 0.033) for the lateral position only. Hypotension incidence and ephedrine use increased with decreasing baricity (P = 0.003 and 0.004 respectively), with the hypobaric sitting group having the most frequent incidence of hypotension (76%) as well as cervical blocks (24%; P = 0.032).
Full Text Available Enhanced recovery after surgery (ERAS protocols have been described for patients undergoing colon surgery. Similar protocols for cesarean delivery (CD have been developed recently. CD is one of the most commonly performed surgical procedures, and adoption of ERAS protocols following CD might benefit patients and the health-care system. We aimed to determine which Serbian hospitals reported ERAS protocols, which elements of ERAS protocols were used in CD patients, and whether ERAS and non-ERAS hospitals differed. The survey was sent to all hospitals with obstetric services and 46 of 49 responded. The questionnaire asked whether ERAS protocols had been formally adopted for surgical patients and about their use in CD patients. Specific questions on elements described in other obstetric ERAS protocols for CD included preoperative patient preparation, type of anesthesia and temperature monitoring used for CD, maternal/neonatal contact, and time to discharge. ERAS protocols are used in 24% of surveyed hospitals, 84% admit the patient the day before elective CDs, 87% use a maternal bowel preparation morning on the day of CD, and 80% administer maternal deep venous thrombosis prophylaxis. Only 33% remove IV in the first postoperative day, and 89% of women do not eat solid food until the day following their CD. Neuraxial anesthesia is used in 46% of elective CDs in ERAS hospitals compared to 9% in non-ERAS hospitals (P < 0.01, and neuraxial narcotics for post CD analgesia are given more often in ERAS hospitals. Thirty-six percentage of ERAS patients are discharged within 3 days vs. none in the non-ERAS group. Few elements of ERAS protocols reported from other centers outside Serbia are employed in Serbian hospitals performing CD. Despite significant changes that have been made recently in CD care, enhanced recovery after CD could be significantly improved in Serbian hospitals.

To evaluate whether the characteristics of the radiological uterine myometrial discontinuity (RMD) is associated with maternal-neonatal outcomes and post-cesarean section (CS) complications. A secondary aim was to describe the evolution of the CT uterine surgical incision and the related outcome of a subsequent trial of labor after cesarean (TOLAC). Single center retrospective cohort study of CT scans was performed within 6 weeks from cesarean delivery. Demographic characteristics of patients were recorded (age, intrapartum fever, CS data, and hospital stay length). Abdominopelvic CT scans were performed using a multidetector CT (16 or 256 slice) with intravenous contrast material. CT analysis was performed by two radiologists in consensus. The RMD seen as low attenuation gap in expected incision site was assessed for: visualization, thickness, and presence of gas. Logistic regression analysis was fitted to assess the relationship of the delivery-CT time interval with the presence of RMD and gas. Of a total of 75,791 births during the study period there were 8775 CS (11.6%). The study group consisted of 101 CTs in 84 woman after CS. RMD defined in 73 (72.2%) of all CT exams; the mean RMD thickness was 7 mm ± 3.9, "RMD gas" observed in 15 (17.9%) of CT exams. RMD thickness or gas presence were strongly associated with a CS-1st CT exam time interval of less than 7 days, OR 5.8 [CI 1.5-22.6], p = 0.010, but not with maternal, delivery, or neonatal characteristics. A subsequent successful vaginal birth was achieved in 75% of the patients with no uterine rupture, regardless of the RMD gas presence. RMD gas visualization on CT is not associated with febrile morbidity, cesarean characteristics, and subsequent TOLAC results. RMD gas is a normal post-operative finding and should not lead to changes in the postpartum delivery complication management or recommendations for the future mode of delivery.

A case of Couvelaire uterus with placenta accreta found during scheduled repeat low transverse Cesarean section will be discussed within this article. First described in the 1900s, Couvelaire syndrome, also known as uteroplacental apoplexy, is a rare form of nonfatal placenta abruption complication. The case involves a 30-year-old gravida 3 para 2 otherwise healthy female with an uncomplicated pregnancy and two previous cesarean deliveries without complication. She received routine prenatal care. During her pregnancy, she did not experience any symptoms such as vaginal bleeding or abdominal pain. After delivering a healthy female, there were several unsuccessful attempts to remove the placenta from the uterus. Upon inspection, the uterus was found have dark purple patches with ecchymosis and indurations, diagnostic of Couvelaire uterus. Furthermore, there was high clinical suspicion for placenta accreta as the 30-minute mark approached without placenta detachment. A telephonic emergency review with the wet desk radiologist of the 18-week ultrasound revealed high suspicion for placenta accreta. A Cesarean hysterectomy was performed for prevention of significant hemorrhage. This case report may be the first documented association of Couvelaire uterus with placenta accreta. Providers should be vigilant in monitoring for antenatal bleeding, timing of placenta separation, and postpartum hemorrhage. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

Hypotension is common after spinal anesthesia for Cesarean delivery. It is associated with nausea, vomiting, and fetal acidosis. Previous research on phenylephrine excluded obese subjects. We compared the incidence of intraoperative nausea and vomiting (IONV) in obese patients who received a prophylactic phenylephrine infusion vs those who received bolus dosing for the treatment of spinal-induced hypotension. In this multicentre, double-blinded randomized controlled trial, 160 obese women undergoing elective Cesarean delivery under spinal anesthesia were randomized to receive a prophylactic phenylephrine infusion initiated at 50 μg·min -1 (and titrated according to a predefined algorithm) or 100 μg phenylephrine boluses to treat hypotension. Maternal systolic blood pressure was maintained within 20% of baseline. The primary study outcome was the incidence of IONV. Intraoperative nausea and vomiting were significantly reduced in the infusion group compared to the bolus group (46% vs 75%, respectively; relative risk [RR], 0.61; 95% confidence interval [CI], 0.47 to 0.80; P < 0.001). This was associated with significantly reduced need for intraoperative rescue antiemetics (26% vs 42%, respectively; RR, 0.62; 95% CI, 0.40 to 0.97; P = 0.04), but no difference in the incidence of vomiting. Postoperative vomiting at two hours was reduced in the infusion group (11% vs 25%; RR, 0.44; 95% CI, 0.21 to 0.90; P = 0.02);however, there were no differences in the incidence or severity of postoperative nausea, need for rescue antiemetics at two hours and 24 hr, or the incidence of postoperative vomiting at 24 hr. In obese women undergoing Cesarean delivery with spinal anesthesia, prophylactic phenylephrine infusion was associated with less intraoperative nausea, less need for rescue antiemetics, and reduced early postoperative vomiting. www.clinicaltrials.gov (NCT01481740).

Background: Ephedrine was conventionally regarded as the first-choice drug to maintain maternal blood pressure during spinal anesthesia for cesarean delivery, due to its stimulant activity on α- and β-adrenergic receptors. Norepinephrine is a weak β-adrenergic and potent α-adrenergic receptor agonist. Therefore, it may be suitable for maintaining blood pressure with less chronotropic effects compared to ephedrine. Patients and Methods: One hundred and forty healthy patients having cesarean delivery under spinal anesthesia were randomized to Group N (n = 61) who received a prophylactic bolus of norepinephrine 5 μg intravenous (i.v.) at the time of intrathecal block or Group E (n = 61) who received a prophylactic bolus of i.v. ephedrine 10 mg. Rescue i.v. bolus interventions of norepinephrine 5 μg or ephedrine 10 mg were given as required to maintain systolic blood pressure. Maternal and fetal hemodynamic variables, Apgar score, and number of boluses of vasopressors used were recorded. Results: The numbers of maternal hypotension and hypertension episodes and the frequency of bradycardia and tachycardia were significantly lower in Group N compared with Group E (P = 0.02, 0.003, 0.0002, and 0.008, respectively). The number of boluses of vasopressors used was also lower in Group N (P = 0.005). Uterine artery pulsatility index was lower in Group N compared to Group E (P = 0.01) when measured 5 min after spinal anesthesia. Moreover, it was higher at 5 min in Group E when compared with the baseline readings in the same group (P = 0.001). Conclusions: Norepinephrine is a suitable and potent drug to counterbalance the hemodynamic effects of spinal anesthesia during cesarean delivery.

The rate of obesity among US women has been increasing, and obesity is associated with increased risk of surgical site infection (SSI) following cesarean delivery. The optimal perioperative antibiotic prophylactic regimen in this high-risk population undergoing cesarean delivery is unknown. To determine rates of SSI among obese women who receive prophylactic oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery. Randomized, double-blind clinical trial comparing oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery for the prevention of SSI in obese women (prepregnancy BMI ≥30) who had received standard intravenous preoperative cephalosporin prophylaxis. Randomization was stratified by intact vs rupture of membranes prior to delivery. The study was conducted at the University of Cincinnati Medical Center, Cincinnati, Ohio, an academic and urban setting, between October 2010 and December 2015, with final follow-up through February 2016. Participants were randomly assigned to receive oral cephalexin, 500 mg, and metronidazole, 500 mg (n = 202 participants), vs identical-appearing placebo (n = 201 participants) every 8 hours for a total of 48 hours following cesarean delivery. The primary outcome was SSI, defined as any superficial incisional, deep incisional, or organ/space infections within 30 days after cesarean delivery. Among 403 randomized participants who were included (mean age, 28 [SD, 6] years; mean BMI, 39.7 [SD, 7.8]), 382 (94.6%) completed the trial. The overall rate of SSI was 10.9% (95% CI, 7.9%-14.0%). Surgical site infection was diagnosed in 13 women (6.4%) in the cephalexin-metronidazole group vs 31 women (15.4%) in the placebo group (difference, 9.0% [95% CI, 2.9%-15.0%]; relative risk, 0.41 [95% CI, 0.22-0.77]; P = .01). There were no serious adverse events, including allergic reaction, reported in either the antibiotic group or the placebo group. Among obese women

Our purpose was to evaluate maternal nosocomial infection rates according to the incision technique used for caesarean delivery, in a routine surveillance study. This was a prospective study of 5123 cesarean deliveries (43.2% Joel-Cohen, 56.8% Pfannenstiel incisions) in 35 maternity units (Mater Sud Est network). Data on routine surveillance variables, operative duration, and three additional variables (manual removal of the placenta, uterine exteriorization, and/or cleaning of the parieto-colic gutter) were collected. Multiple logistic regression analysis was used to identify independent risk factors for infection. The overall nosocomial infection and endometritis rates were higher for the Joel-Cohen than Pfannenstiel incision (4.5% vs. 3.3%, 0.8% vs. 0.3%, respectively). The higher rate of nosocomial infections with the Joel-Cohen incision was due to a greater proportion of patients presenting risk factors (i.e., emergency delivery, primary cesarean, blood loss > or =800 mL, no manual removal of the placenta and no uterine exteriorization). However, the Joel-Cohen technique was an independent risk factor for endometritis. The Joel-Cohen technique is faster than the Pfannenstiel technique but is associated with a higher incidence of endometritis.
Full Text Available Background: Very preterm birth (26-32 weeks has an important effect on infant morta-lity and disability of infancy. The aim of this study was to investigate the prevalence of very preterm delivery and early neonatal morbidity (the first 28 days after birth.Methods: In this cross-sectional retrospective study, among 4393 delivery in Arash Women's Hospital in Tehran, 59 deliveries were very preterm that resulted in 79 very preterm neonate births. We assessed maternal risk factors and neonatal complications in women who were admitted for delivery from March 2009 to March 2010.Results: Among 59 pregnant women, 17 (12/27% had multiple pregnancies and 17 (12/27% had premature rupture of fetal membranes. Caesarean section method was more common than normal vaginal delivery (46 cases- 97/77%. Women aged 18 to 35 had the highest rate of preterm delivery (45/86%. Among 79 very preterm neonates about half of them were very low birth weight, 74 neonates (93/67% suffered from respiratory distress syndrome and 13 deaths were reported.Conclusion: Premature birth is a multi-factorial phenomenon. Identifying maternal risk factors and increasing knowledge about it can decrease the rate of preterm labor. The prevention of premature labor is better than cure. Further prospective studies with large number of patients and long-term follow-up are recommended for better understanding of the phenomenon.

To assess the association of a sonographic estimated fetal weight (sonoEFW) with the risk of cesarean delivery in women with macrosomic or small for gestational age (SGA) infants. Retrospective cohort of singleton deliveries >24 weeks by one MFM practice from 2005 to 2014. We included all patients who delivered an infant with macrosomia (birth weight ≥4000 g) or SGA (birth weight cesarean delivery between patients who did and did not have a sonoEFW within four weeks of delivery. Regression analysis was performed to control for any differences in baseline characteristics. In patients with macrosomic infants (n = 352), the risk of cesarean delivery was significantly higher in the sonoEFW group (45.3% versus 17.6%, aOR 2.144, 95% CI: 1.06-4.34). When we restricted the analysis to the subgroup of 265 patients who attempted vaginal delivery, our results were similar (22.3% versus 9.1%, aOR 2.73, 95% CI: 1.15-6.48). In patients with an SGA infant (n = 614), the risk of cesarean delivery was not higher in the sonoEFW group (37.4% versus 24.1%, aOR 1.23, 95% CI: 0.80-2.07), nor in those who attempted vaginal delivery (19.8% versus 13.7%, aOR 1.17, 95% CI: 0.62-2.21). A sonoEFW prior to delivery is independently associated with cesarean delivery in women with macrosomic infants, but not those with SGA infants. This should be considered when deciding to obtain a sonoEFW at the end of pregnancy, particularly if not for an accepted indication.

As rates for cesarean births continue to rise, more women are faced with the choice to plan a vaginal or a repeat cesarean birth after a previous cesarean. The objective of this population-based retrospective cohort study was to compare the safety of planned vaginal birth with cesarean birth after 1-2 previous cesarean sections. We identified singleton term births in British Columbia from 2000 to 2008 using data from the British Columbia Perinatal Data Registry. Women carrying a singleton fetus in cephalic presentation at term (37-41 weeks of gestation completed) with 1-2 prior cesarean births were included. Those with gestational hypertension, pre-existing diabetes and cardiac disease were excluded. Maternal and neonatal outcomes were classified as either life-threatening or non-life threatening. We compared outcomes among women with none versus at least 1 previous vaginal birth, by planned method of delivery. We estimated relative risks (RR) and 95% confidence intervals (CI) for composite outcomes using Poisson regression. Of the 33 812 women in the sample, 5406 had a history of vaginal delivery and 28 406 did not. The composite risk for life-threatening maternal outcomes was elevated among women planning vaginal compared with cesarean birth both with and without a prior vaginal birth (RR 2.06, 95% CI 1.20-3.52) and (2.52, 95% CI 2.04-3.11). Absolute differences (attributable risk [AR]) were 1.01% and 1.31% respectively. Non-life threatening maternal outcomes were decreased among women planning a vaginal birth if they had had at least 1 prior vaginal delivery (RR 0.51, 95% CI 0.33-0.77; AR 1.17%). The composite risk of intrapartum stillbirth, neonatal death or life-threatening neonatal outcomes did not differ among women planning vaginal or cesarean birth with a prior vaginal delivery and non-life threatening neonatal outcomes were decreased, (RR 0.67, 95% CI 0.52-0.86); AR 1.92%). After 1 or 2 previous cesarean births, risks for adverse outcomes between planned

Objective To determine whether patient-perceived pressure from clinicians for labor induction or cesarean delivery is significantly associated with having these procedures. Data Sources/Study Setting Listening to Mothers III, a nationally representative survey of women 18–45 years who delivered a singleton infant in a U.S. hospital July 2011–June 2012 (N = 2,400). Study Design Multivariate logistic regression analysis of factors associated with perceived pressure and estimation of odds of induction and cesarean given perceived pressure. Principal Findings Overall, 14.8 percent of respondents perceived pressure from a clinician for labor induction and 13.3 percent for cesarean delivery. Women who perceived pressure for labor induction had higher odds of induction overall (adjusted odds ratio [aOR]: 3.51; 95 percent confidence interval [CI]: 2.5–5.0) and without medical reason (aOR: 2.13; 95 percent CI: 1.3–3.4) compared with women who did not perceive pressure. Those perceiving pressure for cesarean delivery had higher odds of cesarean overall (aOR: 5.17; 95 percent CI: 3.2–8.4), without medical reason (aOR: 6.13; 95 percent CI: 3.4–11.1), and unplanned cesarean (aOR: 6.70; 95 percent CI: 4.0–11.3). Conclusions Patient-perceived pressure from clinicians significantly predicts labor induction and cesarean delivery. Efforts to reduce provider–patient miscommunication and minimize potentially unnecessary procedures may be warranted. PMID:25250981

To investigate the effects of a physiotherapy program on incision pain and functional activities in the early post-cesarean period. Fifty women were evaluated after Cesarean operation with regard to times of ambulation and return of bowel activity, intensity of incision pain, difficulty in functional activities and number of analgesics required additional to routine pain control procedure. Twenty-four women received only routine nursing care, and a physiotherapy program was applied to the study group (n = 26), additionally. Postoperative ambulation and return of bowel activity were earlier in the study group (p physiotherapy program in the early post-cesarean period in a wider perspective than the current literature, and are considered to be valuable for increasing the quality and productivity of the postnatal care, therefore improving well-being after childbirth.
Full Text Available Respiratory distress syndrome (RDS represents one of the major causes of mortality among preterm infants, and the best approach to treat it is an open research issue. The use of perfluorocarbons (PFC along with non-invasive respiratory support techniques has proven the usefulness of PFC as a complementary substance to achieve a more homogeneous surfactant distribution. The aim of this work was to study the inhaled particles generated by means of an intracorporeal inhalation catheter, evaluating the size and mass distribution of different PFC aerosols. In this article, we discuss different experiments with the PFC perfluorodecalin (PFD and FC75 with a driving pressure of 4–5 bar, evaluating properties such as the aerodynamic diameter (Da, since its value is directly linked to particle deposition in the lung. Furthermore, we develop a numerical model with computational fluid dynamics (CFD techniques. The computational results showed an accurate prediction of the airflow axial velocity at different downstream positions when compared with the data gathered from the real experiments. The numerical validation of the cumulative mass distribution for PFD particles also confirmed a closer match with the experimental data measured at the optimal distance of 60 mm from the catheter tip. In the case of FC75, the cumulative mass fraction for particles above 10 µm was considerable higher with a driving pressure of 5 bar. These numerical models could be a helpful tool to assist parametric studies of new non-invasive devices for the treatment of RDS in preterm infants.

The trend of increasing cesarean section rates had evoked worldwide attention. Many approaches were introduced to diminish cesarean section rates. Vaginal birth after cesarean section (VBAC) is a route of delivery with diverse agreements. In this study, we try to reveal the world trend in VBAC and our experience of a 10-year period in a medical center in northern Taiwan. This is a retrospective study of all women who underwent elective repeat cesarean delivery or trial of labor after cesarean (TOLAC) following primary cesarean delivery by a general obstetrician-gynecologist in the Tamshui Branch of MacKay Memorial Hospital (Taipei, Taiwan) between 2006 and 2015. We excluded cases of preterm labor, two or more cesarean deliveries, and major maternal diseases. We compared the characteristics and outcomes between these groups. We included 400 women with subsequent pregnancies who underwent elective repeat cesarean delivery or TOLAC during the study period. Among the study population, 112 women were excluded and 11 underwent repeat VBAC. A total of 204 (73.65%) cases underwent elective repeat cesarean delivery and 73 (26.35%) chose TOLAC. The rate of successful VBAC among the women who chose TOLAC was 84.93%. With respect to maternal and fetal safety, and success rates and adverse effects of VBAC, the results of this study are promising and compatible with the global data. It shows that a trial of VBAC can be offered to pregnant women without contraindications with high success rates. Copyright © 2017 Taiwan Association of Obstetrics & Gynecology.

Cesarean section rates have risen dramatically in China within the past 25 years, particularly driven by non-medical factors and maternal requests. One major reason women request cesareans is the fear of labor pain, in a country where a minority of women are given any form of pain relief during labor. Drawing upon ethnographic fieldwork and in-depth interviews with 26 postpartum women and 8 providers at a Shanghai district hospital in June and July of 2015, this article elucidates how perceptions of labor pain and the environment of pain relief constructs the cesarean on maternal request. In particular, many women feared labor pain and, in a context without effective pharmacological pain relief or social support during labor, they came to view cesarean sections as a way to negotiate their labor pain. In some cases, women would request cesarean sections during labor as an expression of their pain and a call for a response to their suffering. However, physicians, under recent state policy, deny such requests, particularly as they do not view pain as a reasonable indication for a cesarean birth. This disconnect leads to a mismatch in goals for the experience of birth. To reduce unnecessary C-sections, policy makers should instead address the lack of pain relief during childbirth and develop other means of improving the childbirth experience that may relieve maternal anxiety, such as allowing family members to support the laboring woman and integrating a midwifery model for low-risk births within China's maternal-services system.

To compare maternal, fetal and placental trace element (magnesium, zinc and copper) and heavy metal (cadmium and lead) and maternal vitamin (retinol, α [alpha]-tocopherol, vitamin D 3 , 25-hydroxyvitamin D 3 and 1,25-dihydroxyvitamin D 3 ) levels in preterm deliveries with and without preterm premature rupture of membranes (PPROM). Sixty-eight patients giving birth preterm were grouped into preterm deliveries with PPROM (n = 35) and without PPROM (n = 33). Following delivery, maternal and umbilical cord blood sera and placental tissue samples were obtained. While magnesium, zinc, copper, cadmium and lead levels were measured in all samples, the levels of retinol, α-tocopherol, vitamin D 3 , 25-hydroxyvitamin D 3 and 1,25-dihydroxyvitamin D 3 were measured only in maternal serum. While magnesium level in maternal serum and zinc levels in both maternal and umbilical cord sera were lower, placental magnesium level was higher in preterm deliveries with PPROM (P 0.05). In preterm deliveries with PPROM, 25-hydroxyvitamin D 3 and retinol levels were higher, while vitamin D 3 and 1,25-dihydroxyvitamin D 3 levels were lower in maternal serum (P < 0.05). Maternal serum α-tocopherol levels were similar between the groups. Compared to spontaneous preterm births, PPROM is associated with low maternal serum together with high placental tissue magnesium and low maternal and umbilical cord sera zinc levels. Higher retinol and 25-hydroxyvitamin D 3 and lower vitamin D 3 and 1,25-dihydroxyvitamin D 3 maternal serum levels are also evident in these patients. © 2018 Japan Society of Obstetrics and Gynecology.

Full Text Available In Nigeria, over 900,000 children under the age of five years die every year. Early neonatal death is responsible for a little over 20% of these deaths. Prematurity remains a significant cause of these early neonatal deaths. In some series, it is reported to be responsible for 60-70% of these deaths. This study aimed to determine the prevalence and determinants of pre-term deliveries at the University of Ilorin Teaching Hospital, Ilorin. This was a prospective cohort study conducted over a 9-month period at the University of Ilorin Teaching Hospital. Records of deliveries and data on maternal socio-biological and antenatal variables were collected during this period in order to determine the prevalence and determinants of pre-term deliveries. Out of the 2,489 deliveries that took place over a 9-month period, there were 293 pre-terms, giving a pre-term delivery rate of 120 per 1,000 deliveries. Of the total deliveries, 1,522 singleton deliveries that satisfied inclusion criteria were recruited; 185 of them were pre-term deliveries giving a case:control ratio of 1:7. Significant determinants of pre-term delivery identified were previous pre-term delivery (P=0.001; OR=3.55; 95% CI=1.71-7.30, antepartum hemorrhage (P=0.000; OR=8.95; 95%CI=4.06-19.78, premature rupture of the membranes (P=0.000; OR=6.48; 95%CI=4.33-9.67, maternal urinary tract infection (P=0.006; OR=5.89; 95%CI=1.16-27.57, pregnancy induced hypertension (P=0.007; OR=3.23; 95%CI=2.09-4.99, type of labor (P=0.000; OR=6.44; 95%CI=4.42-9.38 and booking status (P=0.000; OR=4.67; 95%CI=3.33-6.56. The prevalence of pre-term delivery was 120 per 1,000 live births. Factors significantly associated with pre-term delivery were low socio-economic class, previous pre-term delivery, antepartum hemorrhage, premature rupture of fetal membranes, urinary tract infection, pregnancy induced hypertension, induced labor, and booking elsewhere outside the teaching hospital.

The aim of this retrospective analysis was to show the readmission rate of cases with and without early discharge following vaginal or cesarean delivery. After exclusion of cases with pregnancy, delivery and neonatal complications, a total of 14,460 cases who delivered at Zeynep Kamil Women and Children's Health Training and Research Hospital were retrospectively screened from hospital database. Subjects were divided into two groups as Group 1: early discharge (n = 6802) and Group 2: late discharge (n = 7658). Groups were compared in terms of readmission rates and indications for readmission. There were 6802 cases with early discharge whereas the remaining women were discharged after 24 h for vaginal delivery and 48 h following cesarean delivery on regular bases. Among cases with early discharge, 205 (3%) cases readmitted to emergency service with variable indications, while there were 216 (2.8%) readmitted women who were discharged on regular bases. Most common indication for readmission was wound infection in both groups. Neonatal sex distributions were similar between groups (p > .05), where as there was a higher rate of cesarean deliveries in Group 2 (p discharge (p discharges following vaginal or cesarean delivery without any mortality or permanent morbidity and cost analyses revealed 68 Turkish liras lower cost with early discharge.

To evaluate whether type and location of placenta previa affect risk of antepartum hemorrhage-related preterm delivery. We retrospectively studied 162 women with singleton pregnancies presenting placenta previa. Through observation using transvaginal ultrasound the women were categorized into complete or incomplete placenta previa, and then assigned to anterior and posterior groups. Complete placenta previa was defined as a placenta that completely covered the internal cervical os, with the placental margin >2 cm from the os. Incomplete placenta previa comprised marginal placenta previa whose margin adjacent to the internal os and partial placenta previa which covered the os but the margin situated within 2 cm of the os. Maternal characteristics and perinatal outcomes in complete and incomplete placenta previa were compared, and the differences between the anterior and the posterior groups were evaluated. Antepartum hemorrhage was more prevalent in women with complete placenta previa than in those with incomplete placenta previa (59.1% versus 17.6%), resulting in the higher incidence of preterm delivery in women with complete than in those with incomplete placenta previa [45.1% versus 8.8%; odds ratio (OR) 8.51; 95% confidence interval (CI) 3.59-20.18; p placenta previa, incidence of antepartum hemorrhage did not significantly differ between the anterior and the posterior groups. However, gestational age at bleeding onset was lower in the anterior group than in the posterior group, and the incidence of preterm delivery was higher in the anterior group than in the posterior group (76.2% versus 32.0%; OR 6.8; 95% CI 2.12-21.84; p = 0.002). In incomplete placenta previa, gestational age at delivery did not significantly differ between the anterior and posterior groups. Obstetricians should be aware of the increased risk of preterm delivery related to antepartum hemorrhage in women with complete placenta previa, particularly when the placenta is located on the anterior
Full Text Available Objective: This study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery.Materials and methods: We conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in Tehran. Patients were randomized to receive a pump infusion system that was filled with either 0.25% bupivacaine or equal volume of distilled water. A catheter was placed above the fascia and connected to electronic pump for 24 hours. Postoperative analog pain scores and morphine consumption were assessed at 6, 12 and 24 hours. Also time interval to first ambulation, length of hospitalization, complications and patient satisfaction were recorded. Data were analyzed using the SPSS software and P < 0.05 was considered statistically significant. Mann-Whitney u-test, student t-test and chi-square were used. Results: There were no differences in patient demographics and length of hospitalization and patient-generated resting pain scores between the two groups. Pain scores after coughing and leg raise during the first 6 postoperative hours were significantly less in the Bupivacaine group (P<0.001. The total dose of morphine consumption during the 24 hours study period was 2.5 ± 2.5 mg vs. 7.3 ± 2.7 mg for the bupivacaine and control groups, respectively (P<0.001. Compared with the control group, time to first ambulation was shorter in the bupivacaine group (11± 5h vs. 16 ± 4h (P< 0.01. Conclusion: Bupivacaine wound infusion was a simple and safe technique that provides effective analgesia and reduces morphine requirements after cesarean delivery.
Full Text Available Background and Objectives: An important cause of delayed recovery from abdominal surgery is delay in return of bowel Function. The aim of the present study was to assess the effects of chewing sugar free gum after elective Cesarean-delivery on return of bowel function in primiparous women in Hajar hospital of Shahrekord.Methods: In a randomized clinical trial, 120 patients, who were scheduled for elective cesarean were randomly allocated to 2 groups of gum-chewing group (n=60 and control group (n=60 postoperatively. The patients in the gum-chewing group chewed postoperatively sugar free gum 4 times daily as soon as they recovered from anesthesia till the time they passed flatus or defecated. Control group recieved routine postoperative dietary management. The mean scores of postoperative time interval to first hearing of normal bowel sounds, passage of flatus, defecation and sensation of bowel movement were compared between the two groups. The data were then analyzed using chi square and t-test (p<0.05.Results: The mean postoperative time interval to first hearing of normal intestinal sounds (6.5+/-1.5 versus 12.5+/- 2.5 hours, the first passage of flatus (12.2+/-2.0 vs.22.4+/-4.1 hours, first sensation of bowel movement (7.4+/-1.7 versus 15.7+/-3.4 hours and defecation (15.5+/-2.5 versus 23.4+/-4.8 hours were significantly lower in the gum-chewing group compared with control group. (p<0.001. The staying period in the hospital (0.96+/-0.18 versus 1.1+/-34 days was significantly shorter in gum-chewing group. (p<0.001.Conclusion: Chewing gum after elective Cesarean-Delivery is safe, inexpensive and helpful which is well tolerated, and associated with rapid resumption of intestinal function and speeds recovery shorter hospital stay.

The induction-delivery time during Cesarean section is traditionally conducted under light anesthesia because of the possibility of anesthesia-induced neonatal respiratory depression. The serious consequences of such an approach could be the increased risk of maternal intraoperative awareness and exaggerated neuroendocrine and cardiovascular stress response to laryngoscopy, endotracheal intubation, and surgical stimuli. Here, we briefly discuss the various pharmacological options for attenuation of stress response to endotracheal intubation during Cesarean delivery and then focus on remifentanil, its pharmacokinetic properties, and its use in anesthesia, both in clinical studies and case reports. Remifentanil intravenous bolus doses of 0.5-1 μg/kg before the induction to anesthesia provide the best compromise between attenuating maternal stress response and minimizing the possibility of neonatal respiratory depression. Although neonatal respiratory depression, if present, usually resolves in a few minutes without the need for prolonged resuscitation measures, health care workers skilled at neonatal resuscitation should be present in the operating room whenever remifentanil is used.

To compare extra-abdominal repair of the uterine incision at cesarean delivery with in situ repair. The present study was a double-blind randomized controlled trial conducted at a university hospital in Egypt during 2012-2013, and included women with an indication for cesarean delivery. Extra-abdominal repair was used in group 1 (n=500) and in situ repair in group 2 (n=500). The primary outcome measure was the surgery duration. Surgery duration was significantly longer in group 1 than group 2 (49.9±2.3 minutes vs 39.9±1.8 minutes; P<0.001). More patients in group 1 than in group 2 had postoperative moderate-to-severe pain (165 [33.0%] vs 115 [23.0%]; P=0.001) and needed additional postoperative analgesia (100 [20.0%] vs 50 [10.0%]; P<0.001). Moreover, mean time to bowel movement was longer in group 1 than in group 2 (17.0±2.7 hours vs 14.0±1.9 hours; P<0.001). In situ uterine closure is more advantageous than extra-abdominal repair in terms of surgery duration, postoperative pain and need for additional analgesia, and return of bowel movement.

To evaluate the effectiveness of 200 mg of daily vaginal natural progesterone to prevent preterm birth in women with preterm labour. Multicentre, randomised, double-blind, placebo-controlled trial. Twenty-nine centres in Switzerland and Argentina. A total of 385 women with preterm labour (24(0/7) to 33(6/7) weeks of gestation) treated with acute tocolysis. Participants were randomly allocated to either 200 mg daily of self-administered vaginal progesterone or placebo within 48 hours of starting acute tocolysis. Primary outcome was delivery before 37 weeks of gestation. Secondary outcomes were delivery before 32 and 34 weeks, adverse effects, duration of tocolysis, re-admissions for preterm labour, length of hospital stay, and neonatal morbidity and mortality. The study was ended prematurely based on results of the intermediate analysis. Preterm birth occurred in 42.5% of women in the progesterone group versus 35.5% in the placebo group (relative risk [RR] 1.2; 95% confidence interval [95% CI] 0.93-1.5). Delivery at <32 and <34 weeks did not differ between the two groups (12.9 versus 9.7%; [RR 1.3; 95% CI 0.7-2.5] and 19.7 versus 12.9% [RR 1.5; 95% CI 0.9-2.4], respectively). The duration of tocolysis, hospitalisation, and recurrence of preterm labour were comparable between groups. Neonatal morbidity occurred in 44 (22.8%) cases on progesterone versus 35 (18.8%) cases on placebo (RR: 1.2; 95% CI 0.82-1.8), whereas there were 4 (2%) neonatal deaths in each study group. There is no evidence that the daily administration of 200 mg vaginal progesterone decreases preterm birth or improves neonatal outcome in women with preterm labour. © 2014 Royal College of Obstetricians and Gynaecologists.

Purpose Osteogenesis imperfecta (OI) predisposes to recurrent fractures. The moderate-to-severe forms of OI present with antenatal fractures and the mode of delivery that would be safest for the fetus is not known. Methods We conducted systematic analyses on the largest cohort of individuals (n=540) with OI enrolled to-date in the OI Linked Clinical Research Centers. Self-reported at-birth fracture rates were compared in individuals with OI types I, III, and IV. Multivariate analyses utilizing backward-elimination logistic regression model building were performed to assess the effect of multiple covariates including method of delivery on fracture-related outcomes. Results When accounting for other covariates, at-birth fracture rates did not differ based on whether delivery was by vaginal route or by cesarean section (CS). Increased birth weight conferred higher risk for fractures irrespective of the delivery method. In utero fracture, maternal history of OI, and breech presentation were strong predictors for choosing CS for delivery. Conclusion Our study, the largest to analyze the effect of various factors on at-birth fracture rates in OI shows that delivery by CS is not associated with decreased fracture rate. With the limitation that the fracture data were self-reported in this cohort, these results suggest that CS should be performed only for other maternal or fetal indications, but not for the sole purpose of fracture prevention in OI.

Artificially sweetened (AS) and sugar-sweetened (SS) beverages are commonly consumed during pregnancy. A recent Danish study reported that the daily intake of an AS beverage was associated with an increased risk of preterm delivery. We examined the intake of AS and SS beverages in pregnant women to replicate the Danish study and observe whether AS intake is indeed associated with preterm delivery. This was a prospective study of 60,761 pregnant women in the Norwegian Mother and Child Cohort Study. Intakes of carbonated and noncarbonated AS and SS beverages and use of artificial sweeteners in hot drinks were assessed by a self-reported food-frequency questionnaire in midpregnancy. Preterm delivery was the primary outcome, and data were obtained from the Norwegian Medical Birth Registry. Intakes of both AS and SS beverages increased with increasing BMI and energy intake and were higher in women with less education, in daily smokers, and in single women. A high intake of AS beverages was associated with preterm delivery; the adjusted OR for those drinking >1 serving/d was 1.11 (95% CI: 1.00, 1.24). Drinking >1 serving of SS beverages per day was also associated with an increased risk of preterm delivery (adjusted OR: 1.25; 95% CI: 1.08, 1.45). The trend tests were positive for both beverage types. This study suggests that a high intake of both AS and SS beverages is associated with an increased risk of preterm delivery.

The aim of our study is to determine prevalence and clinical significance of the presence of amniotic fluid "sludge" among asymptomatic patients at high-risk for spontaneous preterm delivery, prospectively. In our study, 99 patients at high risk for spontaneous preterm delivery were evaluated for the presence of amniotic fluid sludge with transvaginal ultrasonography at 20-22, 26-28, and 32-34 gestational weeks, prospectively; between August 2009 and October 2010 in Hacettepe University Hospital. And, these patients were followed up for their delivery weeks and pregnancy outcomes. We defined the high-risk group as the patients possessing one or more of the followings; a history of spontaneous preterm delivery, recent urinary tract infections, polyhydramnios, uterine leiomyomas, müllerian duct anomalies, and history of cone biyopsy or LEEP. Patients with multiple gestations, placenta previa, fetal anomalies, or symptoms of preterm labor at first examination were excluded. We have obtained ethical board approval from Hacettepe University (16.07.2009-HEK/No:09-141-59). The prevalence of amniotic fluid sludge in the study population was 19,6% (18/92). The rates of spontaneous preterm delivery at preterm delivery (p = 0.002). A higher proportion of neonates born to patients with amniotic fluid sludge had a neonatal morbidity (50% (9/18) vs. 24,3% (18/74), p = 0.044) and di
