    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).

    The evaluation of the effect of repeat cesarean sections in adolescent pregnancies on the morbidity, obstetric and perinatal results. We reviewed the patient file and hospital records of patients who underwent at least one cesarean section among adolescent age group pregnant women who gave birth at our clinic between January 2010 and May 2013. The patients were divided into two groups as the patients who underwent the second cesarean section (116 patients) and those who underwent the third cesarean section (36 patients). The demographic data, maternal data and obstetric and perinatal results of the patients were evaluated. A significant difference was present between the patients in the evaluation of the total number of examinations during pregnancy (P = 0.001), total maternal weight gain during pregnancy (P = 0.006), and the first examination gestational age (P = 0.006) and all values were less favorable in the third cesarean group. The gestational week at birth (P cesarean section were statistically significantly lower than the second cesarean section. The third cesarean cesarean was found to cause a significant risk increase for placenta accreta risk in adolescent pregnancies (P = 0.042). The increasing number of cesarean sections in the adolescent group is seen to be a significant risk factor for low gestational week of birth, low birth weight and related morbidities. The most important reason for the increased morbidity with increasing cesarean sections in the adolescent age has been defined as placenta accreta.

    Despite the temporal increase in cesarean deliveries, the extent to which maternal age, period, and maternal birth cohorts may have contributed to these trends remains unknown. We performed an analysis of 123 million singleton deliveries in the United States (1979-2010). We estimated rate ratio (RR) with 95% confidence interval (CI) for primary and repeat cesarean deliveries. We examined changes in cesarean rates with weighted Poisson regression models across three time-scales: maternal age, year of delivery, and birth cohort (mother's birth year). The primary cesarean rate increased by 68% (95% confidence interval [CI]: 67%, 69%) between 1979 (11.0%) and 2010 (18.5%). Repeat cesarean deliveries increased by 178% (95% CI: 176, 179) from 5.2% in 1979 to 14.4% in 2010. Cesarean rates increased with advancing age. Compared with 1979, the RR for the period effect in primary and repeat cesarean deliveries increased up to 1990, fell to a nadir at 1993, and began to rise thereafter. A small birth cohort effect was evident, with women born before 1950 at increased risk of primary cesarean; no cohort effect was seen for repeat cesarean deliveries. Adjustment for maternal BMI had a small effect on these findings. Period effects in primary cesarean were explained by a combination of trends in obesity and chronic hypertension, as well as demographic shifts over time. Maternal age and period appear to have important contributions to the temporal increase in the cesarean rates, although the effect of parity on these associations remains undetermined.

    Surgical complications were compared between patients with three or less prior cesarean deliveries and four or more prior cesarean deliveries. Records of 120 patients who had undergone cesarean sections (CSs) in our Department of Obstetrics and Gynecology, between August and November 2015, were retrospectively studied. Cases were reviewed on the basis of age, type of operation, type of anesthesia, number of CSs, time of hospitalization, and intra-operative and post-operative complications. Cesarean sections had been performed on 62 (51.7%) patients whose cesarean number was three or less, while 58 (48.3%) patients had multiple CSs four or more. Patients with four or more prior cesareans had an increased rate of intra-abdominal adhesions, compared with the other group. There was no significant difference in the gestational weeks, neonatal admission rate, incidence of cesarean hysterectomy, uterine scar rupture, placenta previa with placental invasion anomalies, bladder and bowel injuries, incidence of peripartum hemorrhage and blood transfusion rate between the two groups. There is no greater risk of maternal complications in patients with four or more prior cesareans, excepting intra-abdominal adhesions.

    Full Text Available Background: A spectacular development has been experimented in the Anesthesiology branch in the last few years in the different areas of its competence in which the attendance activity on obstetric patients as well as every aspect related with its adequate practice is of a great importance. Objective: to evaluate the efficacy of epidural anesthesia in repetitive cesarean. Methods: a descriptive retrospective study of a series of cases (112in which epidural anesthesia in repetitive cesarean was applied from January 2001 to December 2001 in the surgical unit of the Gynecological obstetric service at the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ in Cienfuegos city, Cuba. Some variables such as fixation time of the anesthesia, its duration, transurgical and postsurgical hemodynamic behavior, complications related with the anesthesia, evaluation of the new born baby and, the level of satisfaction of the patients were analyzed. Results: The immediate transurgical and postsurgical hemodynamic behavior was stable predominating normotension and the normal cardiac frequency. The complications related to anesthesia were minimal. The level of satisfaction of the patients was elevated. No alterations in new born babies were presented. As a conclusion, it may be stated that epidural anesthesia in repetitive cesarean is a safety and reliable anesthetic method.

    We present a case in which there was optimal management of recurrent cervicovesical fistula. The patient sustained a fistula shortly after a cesarean for cephalopelvic disproportion in the second stage. She underwent an unsuccessful attempt at vaginal repair 3 months postpartum and continued experiencing intermittent urinary leakage through the vagina. She expressed a wish for further childbearing and was counseled to undergo fistula repair at the time of repeat cesarean section. Twenty-seven months after her first delivery, she had a second healthy pregnancy and the repair of her cervicovesical fistula was performed with collagen graft interposition at the time of her elective cesarean section. This case report highlights the importance of surgical timing and comments on various factors that possibly enhance the success of the fistula repair.

    The current literature indicates increasing concern regarding the number of safe cesarean sections which a woman can undergo, mainly in face of the high cesarean section rates, which are growing in Brazil and worldwide. Aimed to describe the prevalence and associated factors of repeat cesarean section in a cohort of Brazilian women who had a cesarean section in the first birth. This is a prospective cohort study using data from the 2004 Pelotas Birth Cohort. The sample included 480 women who had their first delivery in 2004, regardless of the form of delivery, and who had a second delivery identified in the cohort's follow-ups (in 2005, 2006, 2008, and 2010). Descriptive, bivariate and multivariate analyses using Poisson regression with robust error variance were carried out. Among the women who underwent a cesarean section in their first delivery (49.47%), 87.44% had a second surgical delivery. The risk factors for repeat cesarean section included ages 21-34 (PR 1.67, CI 95% 1.07-2.60), not being seen by SUS (Public Healthcare System) in 2004 (PR 2.27, CI 95% 1.44-3.60), and the number of prenatal medical visits, i.e., women with ten or more visits were at 2.33 times higher risk (CI 95% 1.10-4.96) compared to those who had five or fewer visits. The proportion of cesarean sections both in the first and in the subsequent delivery is quite high. This high rate may compromise the reproductive future of the women who undergo consecutive cesarean sections with possible consequent complications and changes in care policies for pregnant women should be implemented.

    Results: A total of 155863 deliveries occurred during the study duration, there were 28.1% (n=43824 cesarean section and (10.1% (n=15664 were the number of previous cesarean section. In 84% (n=13151 had repeat cesarean delivery and 2513 (16% delivered vaginally. A trial of labor was planned in 4035 (25.8% women. The success rate of VBAC was 62.3% with 2513 women had successful vaginal delivery and 1522 (37.7% delivered by emergency repeat cesarean section. Major indication of emergency cesarean section was CPD (52.9%, foetal distress (25.8%, severe PIH/eclampsia (5.0%, previous 2 CS (0.7%, APH (1.4% and others (2.7%. In majority, surgical technique was conventional and in 3.7% the Misgav-Ladach technique was used. Scar dehiscence and surgical complications were observed in 5.4% and 4.0% of cases respectively. Blood transfusion was given in 7.0% and post-operative complications were seen in 6.8%. Perinatal and maternal mortality was 18.0/1000 and 257/100000 deliveries respectively. Conclusions: Safety in childbirth for women with prior cesarean is a major public health concern. Repeat caesarean section and planned vaginal birth after cesarean section are both associated with benefits and harms and correct management represents one of the most significant and challenging issues in obstetric practice.

    To examine hospital variation in intrapartum care and its relationship with cesarean rates. Cross-sectional survey. Connecticut and Massachusetts hospitals providing obstetric services. Nurse managers or other clinical staff knowledgeable about intrapartum care. We assessed labor and delivery unit capacity and staffing, fetal monitoring, labor management, intrapartum interventions, newborn care, quality assurance, and performance review practices. Association of hospital characteristics and intrapartum practices with cesarean rate was evaluated using Wilcoxon exact rank sum test and Kendall's tau-b correlation coefficient. Among 60 eligible hospitals, respondents from 39 hospitals (65%) completed the survey. Cesarean rates varied from 21% to 42% (median = 30%). Regular review of cesarean rates and indications (85%), regular provision of feedback on cesarean rates and indications to physicians (80%), and regular review of vaginal birth after cesarean rates (94%) were commonly performed at responding hospitals. These practices, however, were not associated with hospital cesarean rate. Hospitals that offered cesarean at the request of the woman (p cesarean birth (p cesarean rates than institutions without these practices. Routinely placing an intravenous line (p cesarean rates; having a certified nurse-midwife in house at all times (p = .01) and permitting women to eat during labor (p = .02) were associated with lower cesarean rates.

    This study aims to reduce cesarean section rate and increase rate of vaginal delivery. By using Lean Six Sigma (LSS) methodology, the cesarean section rate was investigated and analyzed through a 5-phase roadmap consisting of Define, Measure, Analyze, Improve, and Control. The principal causes of cesarean section were identified, improvement measures were implemented, and the rate of cesarean section before and after intervention was compared. After patients with a valid medical reason for cesarean were excluded, the main causes of cesarean section were maternal request, labor pain, parturient women assessment, and labor observation. A series of measures was implemented, including an improved parturient women assessment system, strengthened pregnancy nutrition guidance, implementation of painless labor techniques, enhanced midwifery team building, and promotion of childbirth-assist skills. Ten months after introduction of the improvement measures, the cesarean section rate decreased from 41.83% to 32.00%, and the Six Sigma score (ie, Z value) increased from 1.706 to 1.967 (P cesarean section. © 2016 John Wiley & Sons, Ltd.

    2010-01-01

    Background Cultural and ethnic roots impact women's fertility and delivery preferences This study investigated whether the likelihood of cesarean delivery, primary cesarean, and vaginal delivery after cesarean (VBAC) varies by maternal national origin. Methods We conducted a nation-wide, population-based, observational study using secondary data from Taiwan. De-identified data were obtained on all 392,246 singleton live births (≥500 g; ≥20 weeks) born to native-born Taiwanese, Vietnamese and mainland Chinese-born mothers between January 1 2006 and December 31 2007 from Taiwan's nation-wide birth certificate data. Our analytic samples consisted of the following: for overall cesarean likelihood 392,246 births, primary cesarean 336,766 (excluding repeat cesarean and VBAC), and VBAC 55,480 births (excluding primary cesarean and vaginal births without previous cesarean). Our main outcome measures were the odds of cesarean delivery, primary cesarean delivery and VBAC for Vietnamese and Chinese immigrant mothers relative to Taiwanese mothers, using multiple regression analyses to adjust for maternal and neonatal characteristics, paternal age, institutional setting, and major obstetric complications. Results Unadjusted overall cesarean, primary cesarean, and VBAC rates were 33.9%, 23.0% and 4.0% for Taiwanese, 27.6%, 20.1% and 5.0% for mainland Chinese, and 19.3%, 13.9 and 6.1% for Vietnamese respectively. Adjusted for confounders, Vietnamese mothers were less likely than native-born Taiwanese to have overall and primary cesarean delivery (OR = 0.59 and 0.58 respectively), followed by Chinese mothers (both ORs = 0.90 relative to native-born Taiwanese). Vietnamese mothers were most likely to have successful VBAC (OR = 1.58), followed by Chinese mothers (OR = 1.25). Conclusion Immigrant Vietnamese and Chinese mothers have lower odds of cesarean and higher VBAC odds than native-born Taiwanese, consistent with lower cesarean rates prevailing in their home countries

    To evaluate the maternal and neonatal risk related with multiple repeated cesarean sections. A case control study was conducted in a single tertiary maternity and children's center. The outcome of a study group including 122 pregnant women undergoing cesarean section for the fourth or fifth time was compared with a control group comprising 146 women sectioned for the second and third time. All multiple repeated cesarean sections were divided into urgent and elective groups to compare the outcome measures of demographic, neonatal, intra- and post-operative data. Compared with the control group, the study group had significantly lower birth weights (p=0.026), lower Apgar scores at 1 minute (p=0.0001) and 5 minutes (p=0.042), higher numbers of fetal death (p=0.03), higher rate of omentum adhesions (p =0.0001) and peritoneal adhesions (p=0.008), increased risk of cesarean hysterectomy (p = 0.014), increased need for transfusion (p = 0.018), and an increase in hospitalization days (p=0.005). Compared with the elective group, preterm birth incidence was higher (p = 0.01) and birth weight was lower (p=0.004) in the urgent group. The risk for myometrium herniation (p=0.018), need for drainage during operation (p=0.018), and post-operative fever (p =0.001) was also more common in the urgent group. Multiple repeated cesarean sections increase the risks for operative complications and poor perinatal outcomes.

    To examine variation in the cesarean birth rates of women cared for by labor and delivery nurses. Retrospective cohort study. One high-volume labor and delivery unit at an academic medical center in a major metropolitan area. Labor and delivery nurses who cared for nulliparous women who gave birth to term, singleton fetuses in vertex presentation. Data were extracted from electronic hospital birth records from January 1, 2013 through June 30, 2015. Cesarean rates for individual nurses were calculated based on the number of women they attended who gave birth by cesarean. Nurses were grouped into quartiles by their cesarean rates, and the effect of these rates on the likelihood of cesarean birth was estimated by a logit regression model adjusting for patient-level characteristics and clustering of births within nurses. Seventy-two nurses attended 3,031 births. The mean nurse cesarean rate was 26% (95% confidence interval [23.9, 28.1]) and ranged from 8.3% to 48%. The adjusted odds of cesarean for births attended by nurses in the highest quartile was nearly 3 times (odds ratio = 2.73, 95% confidence interval [2.3, 3.3]) greater than for births attended by nurses in the lowest quartile. The labor and delivery nurse assigned to a woman may influence the likelihood of cesarean birth. Nurse-level cesarean birth data could be used to design practice improvement initiatives to improve nurse performance. More precise measurement of the relative influence of nurses on mode of birth is needed. Copyright © 2017 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Cesarean birth rates in the United States reached a high of 27.6% in 2003, a 6% increase over 2002. A cultural conflict appears to exist between the views of those who believe that birth is normal and many cesareans are unnecessary and the views of those who feel that higher rates are justifiable. Childbirth educators can share cultural concepts of normal birth in their classroom.

    To evaluate the effectiveness and safety of postoperative radiotherapy for the treatment of keloid scars administered immediately after Cesarean section. A total of 26 postpartum patients with confirmed keloids resulting from previous Cesarean sections received either 12 or 15 Gy radiotherapy. The radiotherapy was divided into three 6 MeV electron beam fractions administered during the postpartum period immediately following the fi nal Cesarean section. To evaluate ovarian safety, designated doses of radiation were estimated at the calculated depth of the ovaries using a solid plate phantom and an ionization chamber with the same lead cutout as was used for the treatment of Cesarean section operative scars and a tissue equivalent bolus. In total, the control rate was 77% (20 patients), while six (23%) developed focally elevated keloids (ranging from 0.5 to 2 cm in length) in the middle of the primary abdominal scar. Five patients experienced mild hyperpigmentation. Nonetheless, most patients (96%) were satisfied with the treatment results. The estimated percentage of the applied radiation doses that reached the calculated depth of the ovaries ranged from 0.0033% to 0.0062%. When administered during the immediate postpartum period, postoperative electron beam radiotherapy for repeated Cesarean section scars is generally safe and produces good cosmetic results with minimal toxicity.

    Many countries have noted a substantial increase in the cesarean section rate (CSR). Several methods for lowering the CSR have been described. Understanding the impact of clinical audits on the CSR may aid in lowering CSR. Thus, our aim is to elucidate the effect of clinical audits on the CSR. We retrospectively analyzed 3781 pregnant women who gave birth in a medical center between January 2008 and January 2011. Pregnant women who delivered between January 2008 and July 2009 were enrolled as the pre-audit group (n = 1592). After August 2009, all cesarean section cases that were audited were enrolled in the audit group (n = 2189). The CSR was compared between groups. The overall CSR (34.5% vs. 31.1%, adjusted odds ratio [OR] = 0.83, p = 0.008) and the cesarean section rate due to dystocia (9.6% vs. 6.2%, p cesarean section was achieved in 16 (8.2%) of 195 audit cases in the monthly audit conference. In nulliparous pregnant women (n = 2148), multivariate analysis revealed that clinical audit (OR = 0.78), maternal age (OR = 1.10), gestational age at delivery (OR = 0.80), and fetal body weight at birth (OR = 1.0005) were independent predictors of cesarean section (all p cesarean section to reduce the CSR.

    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. 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. 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. 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 that in the context of Iran could work.

    Full Text Available Hector O Chapa, Gonzalo Venegas Women's Specialty Center Dallas, Chapa Medical Consulting, Dallas, TX, USA Objective: The aim of this study was to compare maternal morbidity at repeat cesarean section (CS between use of a Gynecare Interceed™ Absorbable Adhesion Barrier (Gynecare, Somerville, NJ, USA and non-use at primary cesarean delivery. Design: This was a retrospective study of patients in whom an absorbable adhesion barrier was/was not used at their primary CS. Methods: Mean and excessive blood loss, the need for adhesiolysis, and postoperative fever were compared between those in whom a barrier was used at first CS and those in whom a barrier was not used. Visceral injury at repeat cesarean was also compared between the two groups. Results: No statistically significant difference in mean blood loss was noted between the two groups. However, significantly more patients in whom a barrier was not used had excessive intraoperative blood loss (barrier group, 1/53 [1.9%]; no-barrier group, 6/59 [10.1%]; P = 0.04. All seven cases of excessive blood loss had adhesiolysis. Significantly more patients in the no-barrier group underwent adhesiolysis (no-barrier group, 35/59 [59.3%]; barrier group, 7/53 [13.2%]; P = 0.03. No statistical difference in postoperative metritis was noted (1/59 [1.8%] in the barrier group and 1/59 [1.7%] in the no-barrier group; P = 0.99. Only one deserosalization of the bladder dome occurred in a patient in the no-barrier group. Conclusion: Those in whom a barrier was not used at primary CS were more likely to have adhesiolysis and excessive blood loss (>1250 mL at repeat CS. No significant difference in postoperative metritis/fever was noted between groups. Adhesion barrier at primary CS may reduce some aspects of maternal morbidity at repeat CS.

    Full Text Available Global cesarean section (CS rates range from 1% to 52%, with a previous CS being the commonest indication. Labour following a previous CS carries risk of scar rupture, with potential for offspring hypoxic brain injury, leading to high rates of repeat elective CS. However, the effect of delivery by CS on long-term outcomes in children is unclear. Increasing evidence suggests that in avoiding exposure to maternal bowel flora during labour or vaginal birth, offspring delivered by CS may be adversely affected in terms of energy uptake from the gut and immune development, increasing obesity and asthma risks, respectively. This study aimed to address the evidence gap on long-term childhood outcomes following repeat CS by comparing adverse childhood health outcomes after (1 planned repeat CS and (2 unscheduled repeat CS with those that follow vaginal birth after CS (VBAC.A data-linkage cohort study was performed. All second-born, term, singleton offspring delivered between 1 January 1993 and 31 December 2007 in Scotland, UK, to women with a history of CS (n = 40,145 were followed up until 31 January 2015. Outcomes assessed included obesity at age 5 y, hospitalisation with asthma, learning disability, cerebral palsy, and death. Cox regression and binary logistic regression were used as appropriate to compare outcomes following planned repeat CS (n = 17,919 and unscheduled repeat CS (n = 8,847 with those following VBAC (n = 13,379. Risk of hospitalisation with asthma was greater following both unscheduled repeat CS (3.7% versus 3.3%, adjusted hazard ratio [HR] 1.18, 95% CI 1.05-1.33 and planned repeat CS (3.6% versus 3.3%, adjusted HR 1.24, 95% CI 1.09-1.42 compared with VBAC.

    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.

    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 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%.

    Cesarean section (c-section rates have been increasing in many countries, and too frequently this rise does not seem to be justified by clinical grounds. To reduce c-section rates and achieve a proportion of 20% is among the goals of the Italian National Health Plan.

    In the following paper we provide an update on the distribution of rates amongst Italian regions and describe the association between regional hospital volumes and c-section rates. The national c-section rate increased from 31% in 1998 to 36% in 2002.

    The rates varied among regions and ranged from 20% in the Province of Bolzano to 56% in Campania. A significant association was observed between the regional hospital volumes for deliveries and c-section rates, regions with low hospital volumes performed more c-sections than high volume regions.

    Attempts to define, or enforce, an "ideal" cesarean section rate are futile, and should be abandoned. The cesarean rate is a consequence of individual value-laden clinical decisions, and is not amenable to the methods of evidence-based medicine. The influence of academic authority figures on the cesarean rate in the US is placed in historic context. Like other population health indices, the cesarean section rate is an indirect result of American public policy during the last century. Without major changes in the way health and maternity care are delivered in the US, the rate will continue to increase without improving population outcomes.

    It is not well-characterized whether attempting operative vaginal delivery is a safe and effective alternative among women who undergo a trial of labor after cesarean delivery who are unable to complete second-stage labor with a spontaneous vaginal delivery. The purpose of this study was to compare maternal and neonatal outcomes that are associated with attempted operative vaginal delivery with those that are associated with second-stage repeat cesarean delivery without an operative vaginal delivery attempt among women who undergo a trial of labor after cesarean delivery. This is a retrospective secondary analysis of data from Cesarean Registry of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network. Women who underwent a trial of labor after cesarean delivery who were at least 36 weeks gestation were eligible for analysis if they had a live, singleton, nonanomalous gestation in cephalic presentation and reached second-stage labor (defined as complete cervical dilation) with a fetal station of at least +2. The data for women who had an attempted operative vaginal delivery with either forceps or vacuum were compared with those of women who underwent second stage repeat cesarean delivery without operative vaginal delivery attempt. Outcomes of maternal and neonatal complications were compared between groups with bivariable and multivariable analyses. Of 1230 women whose cases were eligible for analysis, 945 women (76.8%) had an attempted operative vaginal delivery. Of those who underwent attempted operative vaginal delivery, 914 women (96.7%) achieved a vaginal delivery. Women who attempted operative vaginal delivery had a lower mean body mass index (30.4±6.0 vs 31.8±5.9 kg/m(2); P=.001) and gestational age (39.5±1.3 vs 39.8±1.2 weeks; P=.012) at delivery and were more likely to be of non-Hispanic black race (30.0% vs 22.1%; P=.002), to have had a previous vaginal delivery (34.9% vs 20

    Full Text Available Introduction: In modern Obstetrics, with rising trends of primary Cesarean section (CS for fetal and maternal interests, pregnancy over the scarred uterus is a challenge to all treating obstetricians. How better the cesarean scar is sutured, its exact fate in next pregnancy is still not measurable. Objective of this study was to evaluate the status of previous cesarean scar during repeat cesarean section (RCS and calculate the maternal morbidity in those cases in a tertiary hospital.   Methods: It was a descriptive, retrospective study conducted at department of Obstetrics of Lumbini Medical College Teaching Hospital. The study was conducted from 15th July 2014 to 14th July 2015. The data were retrieved from the department of Medical Records. Women undergoing RCS were enrolled. The status of scar was evaluated in terms of intact scar, scar rupture, scar dehiscence, thin lower uterine segment, scar placenta previa, and adhesions as indicator of scar integrity.   Results: There were 534 (25.4% CS among 2,098 deliveries during the study period. Ninety one (17.04% of them were RCS. Elective RCS were 73.6% (n=67, and emergency RCS were 26.4% (n=24. Eighty two (90.1% women had RCS once and 9 (9.9% had RCS for second time.

Among nine women of two RCS, three (37.5% had thin scar, five (62.5% had well formed scar,  seven (87.5% had intact scar, and one (12.5% had scar with adhesion. There was no scar dehiscence and no scar rupture in two RCS women.  Adhesions were documented twice higher in women whose primary CS was undertaken outside our hospital. Placenta previa and placenta accreta each were found in two cases.   Conclusion: Most of the scars of repeat Cesarean section were healthy with no scar rupture.

    To determine which clinical practice changes were responsible for a decrease in cesarean rate from 19.2% in 2003 to 15.5% in 2012 at our university hospital treating high risk pregnancies, while verifying the absence of any increase in neonatal morbidity and death. A descriptive retrospective study was undertaken at our labour ward including all patients delivering in 2003 and in 2012. Maternal, obstetrical and neonatal characteristics of the two populations were compared. Cesarean rates were analysed following : (1) Robson classification, (2) some maternal and obstetrical characteristics, and (3) indications for cesarean. Mean age, BMI and rate of scarred uterus significantly increased in 2012. The two populations remained comparable in terms of other criteria studied. The main cause responsible for decrease in cesarean rate was breech presentations (pdecreased our elective cesarean rate by more than 3% without increasing cesarean sections during labour, showing a rise in successful vaginal delivery trials. The impact of in utero transfers on the global rate of cesarean is highly significant since the latter has been divided by half in 10 years in this population considered to be of high risk for cesareans. These significant decreases reflect our experience in allowing vaginal deliveries in breech presentations, and also a better selection of patients for labour induction. Furthermore, it should be noted that increasing vaginal delivery trials in various obstetrical situations participated in this decrease. We clearly found that some indications for elective cesarean can be avoided, such as multiple pregnancies and scarred uterus, thus showing the importance of restricting the first indication for cesarean. Finally, the decrease in cesarean rate had no negative effect on neonatal outcome. Decreasing cesarean rate is possible in a university hospital treating high risk pregnancies. It requires daily obstetrical case by case critical analysis, allowing wide

    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.

    Cesarean section (CS) rates are increasing worldwide but there is some concern with this trend because of potential maternal and perinatal risks. The Robson classification is the standard method to monitor and compare CS rates. Our objective was to analyze CS rates in Brazil according to source of payment for childbirth (public or private) using the Robson classification. Data are from the 2011-2012 "Birth in Brazil" study, which used a national hospital-based sample of 23,940 women. We categorized all women into Robson groups and reported the relative size of each Robson group, the CS rate in each group and the absolute and relative contributions made by each to the overall CS rate. Differences were analyzed through chi-square and Z-test with a significance level of cesarean delivery before labor), group 5 (multiparous, term, cephalic presentation and previous cesarean section) and group 10 (cephalic preterm pregnancies), which accounted for more than 70 % of CS carried out in the country. High-risk women had significantly greater CS rates compared with low-risk women in almost all Robson groups in the public sector only. Public policies should be directed at reducing CS in nulliparous women, particularly by reducing the number of elective CS in these women, and encouraging vaginal birth after cesarean to reduce repeat CS in multiparous women.

    Among European Countries, Italy has the highest rate of cesarean section (36.8%), and in the Campania region this rate reaches 60.0%. We conducted a retrospective cohort study to evaluate whether participation in antenatal classes during pregnancy reduces the rate of cesarean delivery in southern Italy. We selected three local health authorities, with the lowest, the highest, and an intermediate rate of cesarean delivery. The study included 1893 mothers who brought their children for vaccination and were interviewed about their participation in antenatal classes and their obstetric history. The main causes of cesarean section given in the interview were clinical indications (61.0%), previous cesarean section (31.0%) and woman's request (8.0%). When we excluded emergency cesarean delivery, we found a moderate association between participation in antenatal classes and cesarean section reduction (relative risk=1.27; 95% CI=1.08-1.49; in percentage values from 49.3% to 38.8%). Private hospitals and the two local health authorities with higher baseline rates of cesarean section showed an enhanced reduction of these rates. Our paper shows moderate efficacy of antenatal classes, which reduced the occurrence of cesarean section by about 10%. However, the cesarean section rate remained high. As it is possible that different classes have a different level of efficacy, a further study on a standardized model of an antenatal classes is in progress, to assess its efficacy in term of cesarean section reduction, with the purpose of its widespread implementation to the whole region.

    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 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.

    Spinal anesthesia for cesarean section is not a 100% successful technique. At times, despite straightforward insertion and drug administration, intrathecal anesthesia for cesarean section fails to obtain any sensory or motor block. Very few studies and literature are available regarding repeat administration of spinal anesthesia and its drug dosage, especially after first spinal failure in cesarean section lower segment cesarean section (LSCS) due to fear of the excessive spread of drug. The aim of our study is to compare the outcome between two different doses of 0.5% hyperbaric bupivacaine repeated intrathecally after failed spinal. After taking informed consent and Ethical Committee approval this prospective, randomized single-blinded study was conducted in 100 parturients of American Society of Anesthesiologists I-II who were posted for elective LSCS and had Bromage score 0 and no sensory block even at L4 dermatome after 10 min of first spinal anesthesia; were included in the study. Group A (n = 50) patients received 2.4 ml and Group B (n = 50) patients received 2 ml of 0.5% hyperbaric bupivacaine respectively for administering repeat spinal anesthesia. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation, respiratory rate and electrocardiogram were monitored both intra- and post-operatively and complications were recorded. Incidence of high spinal, bradycardia, hypotension, respiratory complications, and nausea vomiting are significantly higher in Group A compared to Group B (P cesarean section with 10 mg of 0.5% hyperbaric bupivacaine provided after first spinal anesthesia, the level of sensory block is below L4 and motor power in Bromage scale is 0.

  6. Cesarean Delivery Rates Vary 10-Fold Among US Hospitals; Reducing Variation May Address Quality, Cost Issues

    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 the association between expanded access to collaborative midwifery and laborist services and cesarean delivery rates. This was a prospective cohort study at a community hospital between 2005 and 2014. In 2011, privately insured women changed from a private practice model to one that included 24-hour midwifery and laborist coverage. Primary cesarean delivery rates among nulliparous, term, singleton, vertex women and vaginal birth after cesarean delivery (VBAC) rates among women with prior cesarean delivery were compared before and after the change. Multivariable logistic regression models estimated the effects of the change on the odds of primary cesarean delivery and VBAC; an interrupted time-series analysis estimated the annual rates before and after the expansion. There were 3,560 nulliparous term singleton vertex deliveries and 1,324 deliveries with prior cesarean delivery during the study period; 45% were among privately insured women whose care model changed. The primary cesarean delivery rate among these privately insured women decreased after the change, from 31.7% to 25.0% (P=.005, adjusted odds ratio [OR] 0.56, 95% confidence interval [CI] 0.39-0.81). The interrupted time-series analysis estimated a 7% drop in the primary cesarean delivery rate in the year after the expansion and a decrease of 1.7% per year thereafter. The VBAC rate increased from 13.3% before to 22.4% afterward (adjusted OR 2.03, 95% CI 1.08-3.80). The change from a private practice to a collaborative midwifery-laborist model was associated with a decrease in primary cesarean rates and an increase in VBAC rates. II.

    To clarify whether an increased cesarean section rate improves the short-term neonatal outcome in singleton term pregnancies with cephalic presentation. A retrospective study of institutional data on the mode of delivery and neonatal outcome. The study included two cohorts: 1998-1999 (n = 7437) and 2004-2005 (n = 8505), since the institutional cesarean section rate increased sharply between these cohorts and has remained stable after the latter study period. The caesarean section rate almost doubled from 6.8 to 11.3 % (p cesarean section rate from a low to a moderate does not improve the short-term neonatal outcome in term singleton pregnancies. On the contrary neonatal intensive care unit admissions increased with increasing caesarean section rate. Furthermore it is possible to achieve good neonatal outcome with a low cesarean section rate.

    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

    Although the influence of the type of institutional setting on the risk of cesarean birth is well documented, less is known about the regional variations in institution-specific cesarean rates within countries. Our purpose was to examine regional variations in cesarean rates across public and private facilities in five Asian countries with a sizeable private sector: Bangladesh, India, Indonesia, Pakistan, and the Philippines. Demographic Health Survey data and a hierarchical model were used to assess regional variations in the mode of delivery while controlling for a wide range of socioeconomic, demographic, and maternal risk factors. The risk of cesarean birth was greater in a private facility than in a government hospital by 36-48 percent in India and Indonesia and by 130 percent in Bangladesh. Regional gradients in cesarean birth were found to be steeper for deliveries in private facilities than in government hospitals in India, Indonesia, and the Philippines. The residents of India's high-use states were 55 percent more likely to undergo a cesarean delivery in a government hospital and 83 percent more likely in a private facility than their counterparts in the medium-use states. Similarly, compared to the residents of the Philippines's medium-use provinces, giving birth in a government facility increased the likelihood of a cesarean delivery by 84 percent and by 173 percent in a private facility. Large regional variations in cesarean rates suggest the need for more informed clinical decision making with respect to the selection of cases for cesarean delivery and the establishment of well-developed guidelines and standards at the provincial or state levels. © 2016 Wiley Periodicals, Inc.

    Objective: The purpose of this study was to compare the risks of elective cesarean hysterectomy with the risks of elective cesarean section followed by remote hysterectomy.Methods: A census of elective cesarean hysterectomies (n = 31) and a random sample of 200 cesarean sections and 200 hysterectomies performed by the authors between 1987 and 1996 were evaluated. Only elective repeat and primary cesarean section patients without labor were selected for study (n = 86). Total abdominal hysterectomies were drawn from the sample (n = 60), excluding cancer cases, patients over 50 years old, and those with ancillary procedures other than adnexectomy and lysis of adhesions. General probability theory was used to calculate a predicted complication rate of cesarean section followed by TAH from the complication rates of the component procedures done independently. This predicted combined complication rate was then compared to the observed rate of complications from cesarean hysterectomy to evaluate the risks of the two alternative treatment regimens.Results: Elective cesarean section and total abdominal hysterectomy had complication rates of 12.8% and 13.4%, respectively. The predicted combined complication rate for elective cesarean section followed by TAH was 24.5%. The observed rate of complications for elective cesarean hysterectomy was much lower (16.1%). Although bleeding complications were similar for the two regimens, the rate of transfusion was higher for cesarean hysterectomy (13.0%) than for cesarean section (0%) and TAH (3.4%) alone. Eighty percent of the cesarean hysterectomy patients would have been candidates for autologous blood donation, had it been available.Conclusions: Elective cesarean hysterectomy has a lower risk of complications than elective cesarean section followed by remote abdominal hysterectomy and should be preferred. Transfusion risks are higher for cesarean hysterectomy but can be decreased by the use of autologous blood.

    To analyze the time trend of the rates of cesarean and vaginal delivery according to the source of financing. This was an ecological study of the time series analysis of cesarean and vaginal delivery rates according to the financing source, carried out in Maringá, Paraná State, Brazil, from 2002 to 2012. Information available at the System of Information on Live Births and at the System of Hospital Information of the Brazilian Unified Health System (SUS) was used for data collection. Moving averages were calculated for all mode of delivery rates in order to smooth random fluctuations in the series, dispersion diagrams were designed between the coefficients and years of the study, and polynomial regression models were estimated from the functional relation observed, with the level of significance set at pdelivery and only 22.9% by vaginal delivery. A total of 22,366 procedures were financed by SUS, 54.6% of them being cesareans. Trend analysis was significant for all the regression models, demonstrating an ascending trend for cesarean delivery and a descending trend for vaginal delivery for both types of financing. The non-SUS cesarean rates always exceeded 90.0% and were more frequent than the SUS cesarean rates, even with a 36.0% increase of the latter during the study period. Based on trend analysis, cesarean deliveries will continue to increase in both health financing sources unless new actions and strategies of reduction are implemented, involving the sociocultural, demographic and obstetric characteristics of women, the training and activity of professionals in the area of obstetrics and an adequate structure of health services for providing vaginal delivery.

    We implemented an evidence-based practice improvement project at a health care facility in the Midwestern United States to address the increasing rate of cesarean surgical site infections. Women who experienced cesarean birth were cared for using a standardized evidence-based protocol including preoperative and postoperative care and education. In addition, a team-created educational video was used by both women and their families during the postoperative period and at home after discharge. This new protocol resulted in a decrease in the rate of cesarean surgical site infections from 1.35% in 2013 to 0.7% in 2014 and 0.36% in 2015. Our interdisciplinary approach to integrate best-practice strategies resulted in decreased infection rates and improved patient satisfaction scores. © 2016 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

  15. Disciplinary discourses: rates of cesarean section explained by medicine, midwifery, and feminism.

    2008-05-01

    In the context of international concern about increasing rates of cesarean sections, we used discourse analysis to examine explanations arising from feminism and the disciplines of medicine and midwifery, and found that each was positioned differently in relation to the rising rates. Medical discourses asserted that doctors are authorities on birth and that, although cesareans are sometimes medically necessary, women recklessly choose unnecessary cesareans against medical advice. Midwifery discourses portrayed medicine as paternalistic toward both women and midwifery, and feminist discourses situated birth and women's bodies in the context of a patriarchally structured society. The findings illustrate the complex ways in which this intervention in birth is discursively constructed, and demonstrate its significance as a site of disciplinary conflict.

    Full Text Available Objective. The improvement of the accuracy of fetal heart rate (FHR pattern interpretation to improve perinatal outcomes remains an elusive challenge. We examined the impact of an FHR centralization system on the incidence of neonatal acidemia and cesarean births. Methods. We performed a regional, population-based, before-and-after study of 9,139 deliveries over a 3-year period. The chi-squared test was used for the statistical analysis. Results. The before-and-after study showed no difference in the rates of acidemia, cesarean births, or perinatal death in the whole population. A subgroup analysis using the 4 hospitals in which an FHR centralization system was continuously connected (compliant group and 3 hospitals in which the FHR centralization system was connected on demand (noncompliant group showed that the incidence acidemia was significantly decreased (from 0.47% to 0.11% without a corresponding increase in the cesarean birth rate due to nonreassuring FHR patterns in the compliant group. Although there was no difference in the incidence of nonreassuring FHR patterns in the noncompliant group, the total cesarean birth rate was significantly higher than that in the compliant group. Conclusion. The continuous FHR centralization system, in which specialists help to interpret results and decide clinical actions, was beneficial in reducing the incidence of neonatal acidemia (pH < 7.1 without increasing the cesarean birth rate due to nonreassuring FHR patterns.

    High cesarean section rates in Brazilian public hospitals and higher rates in private hospitals are well established. Less is known about the relationship between payment source and cesarean section rates within public and private hospitals. We analyzed the 1998, 2003, and 2008 rounds of a nationally representative household survey (PNAD), which includes type of delivery, where it took place, and who paid for it. We construct cesarean section rates for various categories, and perform logistic regression to determine the relative importance of independent variables on cesarean section rates for all births and first births only. Brazilian cesarean section rates were 42 percent in 1998 and 53 percent in 2008. Women who delivered publicly funded births in either public or private hospitals had lower cesarean section rates than those who delivered privately financed deliveries in public or private hospitals. Multivariate models suggest that older age, higher education, and living outside the Northeast region all positively affect the odds of delivering by cesarean section; effects are attenuated by the payment source-hospital type variable for all women and even more so among first births. Cesarean section rates have risen substantially in Brazil. It is important to distinguish payment source for the delivery to have a better understanding of those rates. © 2014 Wiley Periodicals, Inc.

    Induction of labor has become more common in most countries during the last decade. We have compared methods and routines of labor induction as practiced in Norway in 2003 and 2013, and surveyed practices with regard to induction of labor without a medical indication in 2013. A telephone interview with all delivery units in Norway was conducted in 2003. Data on preferred induction methods, use of prostaglandin, dosages, dose intervals and routes of administration were collected. In 2013, the same questionnaire was used, with additional questions on induction of labor without a medical indication. Data on overall cesarean section and induction rates were obtained from the Medical Birth Registry of Norway. From 2003 to 2013 the induction rate increased by 62% and the cesarean section rate by 6%. The cesarean section rate in women with induced labor remained stable at 17.1 and 17.4%, respectively. In 2003, 31 of 43 hospitals used dinoprostone for cervical ripening and induction. In 2013, 34 of 39 hospitals used misoprostol. A cervical balloon was used in three of 43 hospitals in 2003 compared with 31 of 39 in 2013. All but one hospital induced labor without a strict medical indication in 2013. The preferred methods for induction of labor changed within a decade to the use of misoprostol and cervical balloon. Induction of labor without strict medical indications is widely practiced. The changed induction methods have not influenced the cesarean section rates in women with induced labors. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    To compare trends and rates of cesarean section delivery by indication in one academic center. A retrospective analysis of the indications of all cesarean sections performed in Edith Wolfson Medical Center, Holon, Israel, a tertiary healthcare university facility, during 1997-2012 was done. Each delivery was assigned to the primary indication noted for that pregnancy, regardless of other indications reported. Whenever more than one indication was present, the principle indication chosen by the attending obstetrician was chosen for the analysis. The cesarean section rate gradually rose from 15.29% in 1997 to 21.10% in 2012, with an overall cesarean section rate of 20.66%. The cesarean section rate between 1997 and 2000 was 17.52%, between 2001 and 2004 was 18.5%, between 2005 and 2009 was 22.86%, and between 2009 and 2012 was 22.07% (p cesarean section (26.0%), non-reassuring fetal heart rate pattern (18.1%), malpresentation (16.9%), labor dystocia (8.8%), and suspected macrosomia (7.2%). Previous cesarean section persistently increased and was the leading indication throughout the years. Any attempt to reverse this trend must be based on reduction of the primary cesarean section rate. Copyright © 2016. Published by Elsevier B.V.

  20. Birth after previous cesarean delivery: short-term maternal outcomes.

    2010-08-01

    An estimated 40% of the 1.3 million cesarean deliveries performed each year in the United States are repeat procedures. The appropriate clinical management approach for women with previous cesarean delivery remains challenging because options are limited. The risks and benefits of clinical management choices in the woman's health need to be quantified. Thus, we discuss the available published scientific data on (1) the short-term maternal outcomes of trial of labor after cesarean and elective repeat cesarean delivery, (2) the differences between outcomes for both, (3) the important factors that influence these outcomes, and (4) successful vs. unsuccessful vaginal birth after cesarean. For women with a previous cesarean delivery, a successful trial of labor offers several distinct, consistently reproducible advantages compared with elective repeat cesarean delivery, including fewer hysterectomies, fewer thromboembolic events, lower blood transfusion rates, and shorter hospital stay. However, when trial of labor after cesarean fails, emergency cesarean is associated with increased uterine rupture, hysterectomy, operative injury, blood transfusion, endometritis, and longer hospital stay. Care of women with a history of previous cesarean delivery involves a confluence of interactions between medical and nonmedical factors; however, the most important determinants of the short-term outcomes among these women are likely individualized counseling, accurate clinical diagnoses, and careful management during a trial of labor. We recommend a randomized controlled trial among women undergoing a TOLAC and a longitudinal cohort study among women with previous cesarean to evaluate adverse outcomes, with focused attention on both mother and the infant.

    Fifty-eight Danish maternity units, managing 99% of Danish deliveries, participated in a cross sectional study to assess the relationship between use of birth-related technologies, cesarean section rates and perinatal mortality for births after 35 completed weeks of gestation. A regional technology...... index (0-10) was calculated for each maternity unit according to its use of ante and intra partum fetal heart rate monitoring (FHM), hormone analysis (human placental lactogen (HPL) and/or estriol (O3)), fetal blood samples (scalp-pH), intrauterine catheter and umbilical cord-pH. Maternity units using......, and unplanned cesarean section rates in the eight regions were all without significant association to the perinatal mortality in the same regions. For births after the 35th completed week of gestation, this study could not confirm a relationship between different degrees of use of birth-related technologies...

    Full Text Available Abstract Background Cesarean section rates is often used as an indicator of quality of care in maternity hospitals. The assumption is that lower rates reflect in developed countries more appropriate clinical practice and general better performances. Hospitals are thus often ranked on the basis of caesarean section rates. The aim of this study is to assess whether the adjustment for clinical and sociodemographic variables of the mother and the fetus is necessary for inter-hospital comparisons of cesarean section (c-section rates and to assess whether a risk adjustment model based on a limited number of variables could be identified and used. Methods Discharge abstracts of labouring women without prior cesarean were linked with abstracts of newborns discharged from 29 hospitals of the Emilia-Romagna Region (Italy from 2003 to 2004. Adjusted ORs of cesarean by hospital were estimated by using two logistic regression models: 1 a full model including the potential confounders selected by a backward procedure; 2 a parsimonious model including only actual confounders identified by the "change-in-estimate" procedure. Hospital rankings, based on ORs were examined. Results 24 risk factors for c-section were included in the full model and 7 (marital status, maternal age, infant weight, fetopelvic disproportion, eclampsia or pre-eclampsia, placenta previa/abruptio placentae, malposition/malpresentation in the parsimonious model. Hospital ranking using the adjusted ORs from both models was different from that obtained using the crude ORs. The correlation between the rankings of the two models was 0.92. The crude ORs were smaller than ORs adjusted by both models, with the parsimonious ones producing more precise estimates. Conclusion Risk adjustment is necessary to compare hospital c-section rates, it shows differences in rankings and highlights inappropriateness of some hospitals. By adjusting for only actual confounders valid and more precise estimates

  3. The Cesarean Decision Survey

    2013-01-01

    A descriptive study design was used to describe the decision of women having a cesarean surgery. The Cesarean Birth Decision Survey was used to collect data from 101 postpartum women who underwent a cesarean. Most of the surgeries were to primipara women who reported doctor recommendation and increased safety for the baby as the main reasons for the cesarean. Those women who had repeat cesarean surgery all cited their previous cesarean as the main reason for the current surgery. Women’s knowledge of cesarean surgery needs to be assessed early in pregnancy so that appropriate education may be provided. Accurate and ongoing information may decrease the number of women choosing a cesarean surgery. PMID:24868134

    OBJECTIVE To analyze the effects of acupressure at the SP6 point on labor duration and cesarean section rates in parturients served in a public maternity hospital. METHODS This controlled, randomized, double-blind, pragmatic clinical trial involved 156 participants with gestational age ≥ 37 weeks, cervical dilation ≥ 4 cm, and ≥ 2 contractions in 10 min. The women were randomly divided into an acupressure, placebo, or control group at a university hospital in an inland city in the state of Sao Paulo, Brazil, in 2013. Acupressure was applied to the SP6 point during contractions for 20 min. RESULTS The average labor duration was significantly different between the SP6 acupressure group [221.5 min (SD = 162.4)] versus placebo [397.9 min (SD = 265.6)] and versus control [381.9 min (SD = 358.3)] (p = 0.0047); however, the groups were similar regarding the cesarean section rates (p = 0.2526) and Apgar scores in the first minute (p = 0.9542) and the fifth minute (p = 0.7218) of life of the neonate. CONCLUSIONS The SP6 acupressure point proved to be a complementary measure to induce labor and may shorten the labor duration without causing adverse effects to the mother or the newborn. However, it did not affect the cesarean section rate.

    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 compare the incidence of primary and acute cesarean section (CS) and to compare success rate of vaginal delivery. To determine the frequency of maternal complications and evaluation of post-partum condition of the newborn. Prospective, pilot, cohort study. Department of Gynecology and Obstetrics Masaryk University and University Hospital Brno. Analysis of patients with physiologically ongoing singleton pregnancy and term delivery, vertex presentation. Women from the study group (n = 67) underwent myomectomy because of symptomatic, solitary uterine fibroid. Women from the control group (n = 4079) had no history of myomectomy. Analysis was aimed at comparing the incidence of primary and acute CS and comparing success rate of vaginal delivery in both groups and determing the frequency of maternal complications and evaluation of post-partum condition of the newborn. A significantly higher incidence of primary cesarean section was observed in the study group with a history of myomectomy compared to the control group (n = 20, 29.9%; versus n = 396, 9.7 %, p cesarean section in both groups was recorded (n = 7, 10.4%; versus n = 570, 14.0%, p = 0.079). No statistically significant difference in the success of vaginal delivery in both groups was recorded (n = 40, 85.1%; versus n = 3113, 84.5%, p = 0.079). The excessive blood loss was the most frequent complication in both group (n = 9, 13.4%; versus n = 214, 5.2%, p = 0.057). No statistically significant difference in the incidence of uterine rupture and postpartum hysterectomy was recorded. No maternal or fetal death related to childbirth was observed. The history of myomectomy does not increase the incidence of acute cesarean section in the group of strictly selected patients suitable for vaginal birth and has no impact on the success of vaginal delivery. Careful management of labor is a prerequisite for a low risk of maternal complications and good perinatal outcomes.

    Background With cesarean section rates increasing worldwide, clarity regarding negative effects is essential. This study aimed to investigate the rate of subsequent stillbirth, miscarriage, and ectopic pregnancy following primary cesarean section, controlling for confounding by indication. Methods and Findings We performed a population-based cohort study using Danish national registry data linking various registers. The cohort included primiparous women with a live birth between January 1, 1982, and December 31, 2010 (n = 832,996), with follow-up until the next event (stillbirth, miscarriage, or ectopic pregnancy) or censoring by live birth, death, emigration, or study end. Cox regression models for all types of cesarean sections, sub-group analyses by type of cesarean, and competing risks analyses for the causes of stillbirth were performed. An increased rate of stillbirth (hazard ratio [HR] 1.14, 95% CI 1.01, 1.28) was found in women with primary cesarean section compared to spontaneous vaginal delivery, giving a theoretical absolute risk increase (ARI) of 0.03% for stillbirth, and a number needed to harm (NNH) of 3,333 women. Analyses by type of cesarean section showed similarly increased rates for emergency (HR 1.15, 95% CI 1.01, 1.31) and elective cesarean (HR 1.11, 95% CI 0.91, 1.35), although not statistically significant in the latter case. An increased rate of ectopic pregnancy was found among women with primary cesarean overall (HR 1.09, 95% CI 1.04, 1.15) and by type (emergency cesarean, HR 1.09, 95% CI 1.03, 1.15, and elective cesarean, HR 1.12, 95% CI 1.03, 1.21), yielding an ARI of 0.1% and a NNH of 1,000 women for ectopic pregnancy. No increased rate of miscarriage was found among women with primary cesarean, with maternally requested cesarean section associated with a decreased rate of miscarriage (HR 0.72, 95% CI 0.60, 0.85). Limitations include incomplete data on maternal body mass index, maternal smoking, fertility treatment, causes of

    Full Text Available OBJECTIVES: The World Health Organization considers Cesarean section rates of 5-15% to be the optimal range for targeted provision of this life saving intervention. However, access to safe Cesarean section in resource-limited settings is much lower, estimated at 1-2% reported in sub-Saharan Africa. This study reports Cesarean sections rates and indications in Democratic Republic of Congo, Burundi, and Sierra Leone, and describe the main parameters associated with maternal and early neonatal mortality. METHODS: Women undergoing Cesarean section from August 1 2010 to January 31 2011 were included in this prospective study. Logistic regression was used to model determinants of maternal and early neonatal mortality. RESULTS: 1276 women underwent a Cesarean section, giving a frequency of 6.2% (range 4.1-16.8%. The most common indications were obstructed labor (399, 31%, poor presentation (233, 18%, previous Cesarean section (184, 14%, and fetal distress (128, 10%, uterine rupture (117, 9% and antepartum hemorrhage (101, 8%.

Uterine rupture (aOR = 6.6, P<0.001, anterpartum hemorrhage (aOR = 3.6, P<0.001, and cord prolapse (aOR = 2.7, P = 0.017 were associated with early neonatal death. CONCLUSIONS: This study demonstrates that target Cesarean section rates can be achieved in sub-Saharan Africa. Identifying the common indications for Cesarean section and associations with mortality can target improvements in antenatal services and emergency obstetric care.

    Conclusions: As observed in this study, most pregnant women with previous caesarean delivery prefer repeated caesarean delivery rather than VD in their subsequent pregnancy and educational level of pregnant women and doctor′s advice were important factors that influenced this preference. This subject suggests the need to counsel pregnant women with an obstetrician before select delivery type.

    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

    Objective To describe contemporary cesarean delivery practice in the U.S. Study Design Consortium on Safe Labor collected detailed labor and delivery information from 228,668 electronic medical records from 19 hospitals across the U.S., 2002 – 2008. Results The overall cesarean delivery rate was 30.5%. 31.2% of nulliparas were delivered by cesarean section. Prelabor repeat cesarean delivery due to a previous uterine scar contributed 30.9% of all cesarean sections. 28.8% of women with a uterine scar had a trial of labor and the success rate was 57.1%. 43.8% women attempting vaginal delivery had induction. Half of cesarean for dystocia in induced labor were performed before 6 cm of cervical dilation. Conclusion To decrease cesarean delivery rate in the U.S., reducing primary cesarean delivery is the key. Increasing VBAC rate is urgently needed. Cesarean section for dystocia should be avoided before the active phase is established, particularly in nulliparas and in induced labor. PMID:20708166

    The uncontrolled increase in the rate of cesarean section is one of the most controversial issues, and is a primary challenge among health policy makers. This study was conducted to examine the impact of the Iranian health evolution plan on vaginal delivery rate and cesarean section. This cross-sectional study was carried out in 2014. Maternal health data for 2013 and 2014 were used in this study and changes in vaginal delivery and cesarean section were compared before and after the reform, using t-test and Wilkinson test. According to the findings of this study, 64.7% of deliveries in 2013 were performed using cesarean section while it was 58.6% in 2014 (p= 0.772), of which no significant changes were observed. In addition, the percentage of vaginal delivery in 2013 and 2014 were 35.3% and 41.4% respectively (p= 0.00), so a significant increase was found for vaginal delivery. Healthcare reform has led to an increase in the number of vaginal deliveries in hospitals affiliated to Shiraz University of Medical Sciences (SUMS). Due to the limited number of hospitals adhering to the healthcare reform plan to increase vaginal delivery (using private midwife and implementing painless delivery), the reform for decreasing the cesarean rate was not effective enough.

    Large practice variation exists in mode of delivery after cesarean section, suggesting variation in implementation of contemporary guidelines. We aim to evaluate this practice variation and to what extent this can be explained by risk factors at patient level. This retrospective cohort study was performed among 17 Dutch hospitals in 2010. Women with one prior cesarean section without a contraindication for a trial of labor were included. We used multivariate logistic regression analysis to develop models for risk factor adjustments. One model was derived to adjust the elective repeat cesarean section rates; a second model to adjust vaginal birth after cesarean rates. Standardized rates of elective repeat cesarean section and vaginal birth after cesarean per hospital were compared. Pseudo-R(2) measures were calculated to estimate the percentage of practice variation explained by the models. Secondary outcomes were differences in practice variation between hospital types and the correlation between standardized elective repeat cesarean section and vaginal birth after cesarean rates. In all, 1068 women had a history of cesarean section, of whom 71% were eligible for inclusion. A total of 515 women (67%) had a trial of labor, of whom 72% delivered vaginally. The elective repeat cesarean section rate at hospital level ranged from 6 to 54% (mean 29.8, standard deviation 11.8%). Vaginal birth after cesarean rates ranged from 50 to 90% (mean 71.8%, standard deviation 11.1%). More than 85% of this practice variation could not be explained by risk factors at patient level. A large practice variation exists in elective repeat cesarean section and vaginal birth after cesarean rates that can only partially be explained by risk factors at patient level. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    The cesarean section rate has been steadily rising from 35% in 2000 to 40% in 2005 in Iran. The objective of this study was to identify barriers of reduce the cesarean section rate in Iran, as perceived by obstetricians and midwives as the main behavioral change target groups. A qualitative study with purposive sampling was designed in which data were collected through in-depth interviews and document analyses. Hospitals were selected on the bases of being public and or private and their response to the ministry's C-section reduction interventions. The hospital director, obstetricians and midwives from each hospital were included in the study. The classification of barriers suggested by Grol and Wensing was used for the thematic analysis. After 26 in-depth interviews and document analyses, the barriers were identified as: financial, insurance and judicial problems at the economic and political context level; the type and ownership of hospitals, absence of an on call physician, absence of clear job-descriptions for obstetricians and midwives, too many interventions in the delivery process and shortage of human resources and facilities at the organizational context level; distrust and insufficient collaborations between obstetricians and midwives from macro to micro level at the social context level; attitudes toward complications of C-section, reduced capabilities of obstetricians, midwives and residents at the individual professional level; and finally, at the innovation level, vaginal delivery is time consuming, imposes high stress levels and is unpredictable. Changing service providers' behavior is not possible through presentation of scientific evidence alone. A multi-level and multidisciplinary approach using behavior change theories is unavoidable. In future studies, the effect of the barriers should be determined to help policy makers recognize the most effective interventional package.

We aimed in this work to identify factors contributing to increasing rate of CS in central Saudi Arabia.Methods: A retrospective cohort study was conducted at King Abdulaziz Medical City. Two groups of women were included (G1 and G2. G1 had delivered by CS during the year 2002 (CS rate 12%, and G2 had delivered by CS during the year 2009 (CS rate 20%. We compared the included women’s characteristics, neonates, CS indications, and complications. Data were analyzed using SPSS version 15 program. Odds ratios and confidence intervals were calculated to report precision of categorical data results. A P-value of ≤0.05 was considered significant.Results: A total of 198 women were included in G1 and 200 in G2. Both groups had comparable maternal and fetal characteristics; however, absence of antenatal care has resulted in 70% increase in CS deliveries for G2, P=0.008, OR =0.30, CI 0.12–0.76. Previous vaginal surgeries have contributed to tenfold increase in CS deliveries for G2, P=0.006, OR =10.37, CI 1.32–81.78. G2 had eight times increased CS deliveries than G1 due to intrauterine growth restriction, P=0.02, OR =8.21, CI 1.02–66.25, and 80% increased risk of CS was based on maternal demand, P=0.02, OR =0.20, CI 0.02–1.71. Decision taken by less-experienced staff was associated with 2.5-fold increase in CS deliveries for G2, P=0.002, OR =2.62, CI 1.39–4.93. There was a significant increase in CS deliveries under regional analgesia and shorter duration of hospital stay for G2, P=0.0001 and P=0.001, respectively. G2 women had 2.75-fold increase in neonatal intensive care unit admission, P=0.03, OR =2.75, CI 1.06–7.15.Conclusion: CS delivery rate

    Full Text Available Background: FHR monitoring plays the most important role in management of labouring patient when incidence of fetal hypoxia and progressive asphyxia increases. Now a day’s cardiotocography (CTG become a popular method for monitoring of fetal wellbeing and it is assisting the obstetrician in making the decision on the mode of delivery to improve perinatal outcome. The aim of the study was to assess the effect of cardiotocography on perinatal outcome and its correlation with caesarean section rate. Methods: In this prospective observational study 201 gravid women with high risk pregnancy in first stage of labour were taken. Result was assessed in the form of Apgar score at five minute, NICU admission, perinatal mortality and mode of delivery. Statistical analysis is done by using Chi square test and p<0.05 is considered as statistically significant. Results: Perinatal morbidity in the form of NICU admission is higher in nonreactive group as compare to reactive group (75.7% v/s 22.8%. Cesarean section rate for fetal distress were higher in nonreactive group (87.8% in comparison to reactive group (20.5%. So this study suggest that there is significant difference in mode of delivery with increasing chances of caesarean section in cases belong to non-reactive traces (p<0.001. Conclusions: Admission test is non-invasive and the best screening test to evaluate the fetal health and to predict the perinatal outcome but it also associated with increase caesarean section rate.

    Maternal hypotension is a common complication during cesarean section performed under spinal anesthesia. Changes in maternal heart rate with postural changes or values of heart rate variability have been reported to predict hypotension. Therefore, we hypothesized that changes in heart rate variability due to postural changes can predict hypotension. A total of 45 women scheduled to undergo cesarean section under spinal anesthesia were enrolled. A postural change test was performed the day before cesarean section. The ratio of the power of low and high frequency components contributing to heart rate variability was assessed in the order of supine, left lateral, and supine. Patients who exhibited a ⩾two-fold increase in the low-to-high frequency ratio when moving to supine from the lateral position were assigned to the postural change test-positive group. According to the findings of the postural change test, patients were assigned to the positive (n=22) and negative (n=23) groups, respectively. Hypotension occurred in 35/45 patients, of whom 21 (60%) were in the positive group and 14 (40%) were in the negative group. The incidence of hypotension was greater in the positive group (Pcesarean section. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Multiple observational studies have reported an association between neuraxial (epidural, spinal, or combined spinal-epidural) labor analgesia and cesarean delivery. The purpose of this review is to summarize data from controlled trials addressing the question of whether neuraxial labor analgesia causes an increased risk of cesarean delivery. Additionally, the review will discuss whether the timing of initiation of analgesia or the specific type of neuraxial analgesia influences mode of delivery. Finally, the issue of external validity of published trials will be discussed. Copyright © 2012 Elsevier Inc. All rights reserved.

    2016-07-01

    Cesarean scars pose a unique set of risks for women who have had previous cesarean deliveries. Between 1996 and 2007, the rate of trial of labor after previous cesarean delivery increased, along with reported rates of uterine rupture and other complications. Consequently, trial of labor after previous cesarean delivery and resultant vaginal birth after cesarean delivery have decreased and cesarean delivery has increased. With nearly one-third of women having cesarean delivery, the rate of rare complications such as cesarean scar ectopic pregnancy has also increased. An integration of osteopathic manipulative treatment techniques into the management of cesarean deliveries and cesarean scars has yet to be defined. The author presents 4 cases of cesarean delivery in which osteopathic manipulative treatment was integrated with successful outcomes.

    We investigate secret key rates for the quantum repeater using encoding [L. Jiang et al., Phys. Rev. A 79, 032325 (2009), 10.1103/PhysRevA.79.032325] and compare them to the standard repeater scheme by Briegel, Dür, Cirac, and Zoller. The former scheme has the advantage of a minimal consumption of classical communication. We analyze the trade-off in the secret key rate between the communication time and the required resources. For this purpose we introduce an error model for the repeater using encoding which allows for input Bell states with a fidelity smaller than one, in contrast to the model given by L. Jiang et al. [Phys. Rev. A 79, 032325 (2009), 10.1103/PhysRevA.79.032325]. We show that one can correct additional errors in the encoded connection procedure of this repeater and develop a suitable decoding algorithm. Furthermore, we derive the rate of producing entangled pairs for the quantum repeater using encoding and give the minimal parameter values (gate quality and initial fidelity) for establishing a nonzero secret key. We find that the generic quantum repeater is optimal regarding the secret key rate per memory per second and show that the encoded quantum repeater using the simple three-qubit repetition code can even have an advantage with respect to the resources compared to other recent quantum repeater schemes with encoding.

  10. Health implications resulting from the timing of elective cesarean delivery

    2010-06-01

    Full Text Available Abstract Background The literature is nearly unanimous in recommending elective cesarean delivery at 39 weeks of gestation because of the lower rates of neonatal respiratory complications compared to 38 weeks. However, elective cesarean delivery at 39 weeks or more may have maternal and other fetal consequences compared to delivery at 38 weeks, which are not always addressed in these studies. Discussion Between 38 and 39 weeks of gestation, approximately 10% - 14% of women go into spontaneous labor; meaning that a considerable number of women scheduled for an elective cesarean delivery at 39 weeks will deliver earlier in an unscheduled, frequently emergency, cesarean delivery. The incidence of maternal morbidity and mortality is higher among women undergoing non-elective cesarean deliveries than among those undergoing elective ones. Complications may be greater among women after numerous repeat cesarean deliveries and among older women. Other than reducing the frequency of non-elective cesarean deliveries, bringing forward the timing of elective cesarean delivery to 38 weeks, may occasionally prevent intrauterine fetal demise which has been shown to increase with increasing gestational age and to avoid other fetal consequences related to the emergency delivery. All these considerations need to be weighed against the medical and the economic impact of the increase in neonatal morbidity resulting from births at 38 weeks compared to 39 weeks. Summary Until prospective randomized trials are conducted, we are unlikely to be able to precisely answer all risk:benefit questions as to the best timing of scheduled elective cesarean delivery. Older women, and women with numerous prior cesarean deliveries, are of particular concern. It is reasonable to inform the pregnant women of the risk of each of the above options and to respect her autonomy and decision-making.

    Over the past two decades, the incidence of cesarean section in most countries has increased. Cesarean section increases the risk of death and complications in the mother and fetus. Educational interventions based on behavior change models can play an important role in reduce the rate of cesarean section. The aim of our study is investigation the effect of educational intervention based on BASNEF Model on decreasing of cesarean section rate among pregnant women in Khomain County, from June to November 2013. In this interventional study, 140 nulliparous women who were in their last trimester of pregnancy were randomly allocated to case and control groups. Data gathering instrument was a questionnaire based on BASNEF framework. Data were analyzed by SPSS 14 software. The scores of knowledge, attitudes, subjective norms, and enabling factors in the intervention group than the control group showed a significant difference (p cesarean section. By Chi-square test showed that the difference in the type of delivery between the two groups was statistically significant (p cesarean section.

    Full Text Available OBJECTIVE: The aim of the study was to see the fetomaternal outcome of pregnancy with previous cesarean section. METHODS: This study was conducted in the department of OBGYN, BARC Hospital, Mumbai from October 2011 to September 2012, a period of one year. All the pregnant women with previous one cesarean section attending ANC clinic for confinement were included in the study group after giving consent. RESULTS: Out of total75 cases, a total of 23 patients (30.67% were given trial of labor. Out of 23 patients given trial of labor, 12 patients (52.17% had successful VBAC. Commonest indication for unsuccessful trial of labor undergoing repeat cesarean section was non-progress of labor (54.55% and failed IOL (36.67%. Out of 12 patients who had successful VBAC, 3 patients (25% had complication like episiotomy hematoma, perineal tear and cervical tear. No patients had major complications. In present study no baby had apgar score <7 at 1min and 5 min in VBAC group and elective LSCS group. CONCLUSION: The current study concludes that women with a prior cesarean are at increased risk for repeat cesarean section. Vigilance with respect to indication at primary cesarean delivery, proper counseling for trial of labor and proper antepartum and intrapartum monitoring of patients, are key to reducing the cesarean section rates. The antepartum, intrapartum and postpartum complications are more in repeat cesarean section cases. There is no doubt that a trial of labor is a relatively safe procedure, but it is not risk free. Therefore, patient evaluation prior to TOLAC, careful observation throughout labor in a well-equipped unit with around the clock services for emergency surgery and availability of expertise is the backbone for successful VBAC.

    The objective of the study was to determine the rate of complications which accompany cesarean sections at Landspitali University Hospital (LSH). All deliveries by cesarean section from July 1st 2001 to December 31st 2002 were examined in a retrospective manner. Information was collected from maternity records regarding the operation and its complications if they occurred, during or following the operation. During this period 761 women delivered by cesarean section at LSH. The overall complication rate was 35,5%. The most common complications were; blood loss > or =1000 ml (16.5%), post operative fever (12.2%), extension from the uterine incision (7.2%) and need for blood transfusion (4.3%). Blood transfusion was most common in women undergoing cesarean section after attempted instrumental vaginal delivery (20%). Fever and extension from the uterine incision were most common in women undergoing cesarean section after full cervical dilation without attempt of instrumental delivery (19,4%). These complications were least likely to occur if the patient underwent an elective cesarean section. Complications following cesarean section are common, especially if labor is advanced. Each indication for an operative delivery should be carefully weighed and the patient informed accordingly.

    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.

    The medicalization of childbirth as an outcome of social medicalization has been described as a complex sociocultural process that transforms the experiences, suffering and pain - which were formerly managed in the family or community settings - into medical needs. The scope of this paper is to reflect upon the excessive number of cesarean sections in Brazil from a critical and objective standpoint. Data on caesarean section statistics and studies on women's preference on the manner of delivery are discussed in order to contribute to the discussion on the empowerment of the health system consumers. Medicalization is a cultural change that influences the empowerment to cope with the experience of giving birth, as it involves excessive dependency on and abuse of cesarean sections. Furthermore, social networks and movements are discussed as possible facilitators of women's empowerment, as they enable mutual support, sharing of experiences and a contribution to the construction of more balanced relations between women and health professionals. Participation of these networks fosters the collective mobilization of women to insist on their rights from society as a whole.

    During the last decades, there has been an alarming and dramatic increase in the number of cesarean births in both developed and undeveloped countries. This increase has not been clinically justified but, nevertheless, has raised an important number of issues. The aim of this study was to determine the risk factors associated with the high cesarean section rates in Lebanon. This study is based on a sample of 29,270 Lebanese women who were pregnant between 2000 and 2015. Among these, 14,327 gave birth by cesarean section and 14,943 gave birth vaginally. To identify the risk factors of cesarean section, logistic regression was applied as a statistical method using the SPSS statistical package. Of the 29,270 pregnant women included in the study, 49% had cesarean sections while 51% gave birth vaginally. Repeat cesarean section accounted for 23% while vaginal birth after cesarean accounted for only 0.2% of deliveries. In addition, weekdays were associated with a preference of providers to carry out more cesarean sections. According to an analysis of our data using logistic regression, the risk factors associated with the increase in cesarean section rates were advanced maternal age, elective cesarean section, malpresentation of fetus, multiple birth, prolonged pregnancy, prolonged labor, and fetal distress. Based on these results, it is recommended that a new health policy be implemented to reduce the number of unnecessary cesarean deliveries in Lebanon. Copyright © 2017 Australian College of Midwives.

    Full Text Available Background: Prevention of post-spinal hypotension in obstetric patients can be accomplished using intravenous fluid expansion and prophylactic use of sympathomimetic drugs. The affect of combination of colloids and phenylephrine infusion on maternal hemodynamics has not been widely studied and there is no consensus about the dosage required and time of starting its administration. Materials and Methods: This prospective, randomized, double-blind study enrolled 90 healthy term parturients undergoing elective Cesarean delivery under lumbar subarachnoid block (0.5% hyperbaric bupivacaine 10 mg with fentanyl 25 μg. Patients in Group A received prophylactic intravenous phenylephrine infusion (60 μg/minute along with hydroxyl-ethyl-starch cohydration (6% HES 130/0.42;15 ml/kg immediately after subarachnoid block. In Group B, patients received 6% HES cohydration and intermittent intravenous 50 μg boluses of phenylephrine. The efficacy of these in maintaining maternal SBP at 90-110% of baseline and neonatal well-being was evaluated. Results: In Group B, 75.5% of patients required rescue phenylephrine boluses to maintain SBP while maternal hemodynamics were well maintained in Group A and rescue drug was not needed. Reactive hypertension occurred in one patient (2.2% and bradycardia in two patients (4.4% in Group A. Six patients complained of nausea in Group B (13.3% compared to one in Group A. All the newborns had normal Apgar scores and Umbilical arterial pH > 7.2. Conclusion: A combination of colloid cohydration and prophylactic phenylephrine infusion initiated at 60 μg/minute maintained maternal hemodynamics and neonatal well-being during Cesarean deliveries requiring minimum interventions by the anesthesiologist.

    Full Text Available Aim. Comparison of the rate of wound complications, pain, and patient satisfaction based on used subcuticular suture material. Methods. A total of 250 consecutive women undergoing primary and repeat cesarean section with low transverse incision were prospectively included. The primary outcome was wound complication rate including infection, dehiscence, hematoma, and hypertrophic scar formation within a 6-week period after operation. Secondary outcomes were skin closure time, the need for use of additional analgesic agent, pain score on numeric rating scale, cosmetic score, and patient scar satisfaction scale. Results. Absorbable polyglactin was used in 108 patients and nonabsorbable polypropylene was used in 142 patients. Wound complication rates were similar in primary and repeat cesarean groups based on the type of suture material. Skin closure time is longer in nonabsorbable suture material group in both primary and repeat cesarean groups. There was no difference between groups in terms of postoperative pain, need for additional analgesic use, late phase pain, and itching at the scar. Although the cosmetic results tended to be better in the nonabsorbable group in primary surgery patients, there was no significant difference in the visual satisfaction of the patients. Conclusions. Absorbable and nonabsorbable suture materials are comparable in cesarean section operation skin closure.

    To assess use of the C-Model in a tertiary hospital setting in terms of its validity and utility for optimizing the cesarean delivery (CD) rate. A prospective observational study included women admitted for delivery at a university teaching hospital in Assiut, Egypt, in 2015. The women were asked about the demographic and obstetric information needed to calculate the probability of CD using the WHO C-Model. A receiver operating characteristic (ROC) curve comparing the predicted and observed CD rates was constructed. In addition, the mean predicted CD rates were compared with the mean observed CD rates in the 10 groups of the Robson classification. In total, 1000 women were recruited; 38.6% had a previous CD and 13.5% had complications during the current pregnancy. The final mode of delivery was vaginal delivery in 38.7% and CD in 61.3%; the predicted CD rate for this cohort was 45.0%. The area under the ROC curve was 0.928 (95% confidence interval 0.912-0.945). Comparison of the predicted and observed CD rates in the 10 Robson groups showed an overuse of CD ranging from 2% to 50%. The WHO C-Model is valid and can be used in hospital settings to optimize CD rates. © 2017 International Federation of Gynecology and Obstetrics.

    To determine the prevalence of cesarean deliveries in Burkina Faso, analyze the indications for them and the outcomes, and identify factors associated with non-absolute maternal indications for the procedure, as opposed to major obstetric interventions performed to save a woman's life. In a cross-sectional study, we selected and analyzed cesarean deliveries among those most recently performed between May 2009 and April 2010 in all facilities in Burkina Faso. To identify the factors associated with non-absolute maternal indications, we used generalized estimating equations to take into account the clustering of data at the hospital level. The proportion of births by cesarean delivery was 1.5%, with regional variations ranging from 0.8% to 4.5%. They were performed mainly for absolute maternal indications (54.8%). Cesarean deliveries for non-absolute maternal indications were statistically more frequent in private hospitals (OR 2.2; 95% CI, 1.2-4.0), among women in urban areas (OR 1.6; 95% CI, 1.0-2.4), during scheduled cesareans, and in the absence of use of the partogram. This study confirms the small proportion of cesarean deliveries in Burkina, the disparity between urban and rural areas, and the relative preponderance of absolute maternal indications for cesarean delivery.

    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.

    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.

    Full Text Available Background: Since heart rate variability (HRV is associated with average heart rate (HR and respiratory rate (RespRate, alterations in these parameters may impose changes in HRV. Hence the repeatability of HRV measurements may be affected by differences in HR and RespRate. The study aimed to evaluate HRV repeatability and its association with changes in HR and RespRate.Methods: Forty healthy volunteers underwent two ECG examinations seven days apart. Standard HRV indices were calculated from 5-min ECG recordings. The ECG-derived respiration signal was estimated to assess RespRate. To investigate HR impact on HRV, HRV parameters were corrected for prevailing HR. Results: Differences in HRV parameters between the measurements were associated with the changes in HR and RespRate. However, in multiple regression analysis only HR alteration proved to be independent determinant of the HRV differences – every change in HR by 1 bpm changed HRV values by 16.5% on average. After overall removal of HR impact on HRV, coefficients of variation of the HRV parameters significantly dropped on average by 26.8% (p < 0.001, i.e. by the same extent HRV reproducibility improved. Additionally, the HRV correction for HR decreased association between RespRate and HRV. Conclusions: In stable conditions, HR but not RespRate is the most powerful factor determining HRV reproducibility and even a minimal change of HR may considerably alter HRV. However, the removal of HR impact may significantly improve HRV repeatability. The association between HRV and RespRate seems to be, at least in part, HR dependent.

    We aimed to validate a widely used US prediction model for vaginal birth after cesarean (Grobman et al. [8]) and modify it to suit Swedish conditions. Women having experienced one cesarean section and at least one subsequent delivery (n=49,472) in the Swedish Medical Birth Registry 1992-2011 were randomly divided into two data sets. In the development data set, variables associated with successful trial of labor were identified using multiple logistic regression. The predictive ability of the estimates previously published by Grobman et al., and of our modified and new estimates, respectively, was then evaluated using the validation data set. The accuracy of the models for prediction of vaginal birth after cesarean was measured by area under the receiver operating characteristics curve. For maternal age, body mass index, prior vaginal delivery, and prior labor arrest, the odds ratio estimates for vaginal birth after cesarean were similar to those previously published. The prediction accuracy increased when information on indication for the previous cesarean section was added (from area under the receiver operating characteristics curve=0.69-0.71), and increased further when maternal height and delivery unit cesarean section rates were included (area under the receiver operating characteristics curve=0.74). The correlation between the individual predicted vaginal birth after cesarean probability and the observed trial of labor success rate was high in all the respective predicted probability decentiles. Customization of prediction models for vaginal birth after cesarean is of considerable value. Choosing relevant indicators for a Swedish setting made it possible to achieve excellent prediction accuracy for success in trial of labor after cesarean. During the delicate process of counseling about preferred delivery mode after one cesarean section, considering the results of our study may facilitate the choice between a trial of labor or an elective repeat cesarean

Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P<0.01, but these were minor. The rate of blood transfusion and prevalence of changes in hemoglobin level were similar in both groups (P>0.05. In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section.

    Full Text Available Introduction: Cesarean section is considered as a major surgery accompanied by several complications. The present study aimed to determine the effect of educational intervention based on the theory of reasoned action to reduce the rate of cesarean section among pregnant women in Fasa, Southern Iran. Materials and Methods: This quasi-experimental study was performed on 100 (50 participants in each of the control and intervention groups primiparous women in the third trimester of pregnancy admitted to health centers of Fasa city, Fars province, Iran. The data-gathering tool was a multipart questionnaire containing demographic variables and the theory of reasoned action structures. After the pretest, the intervention group underwent exclusive training based on the theory of reasoned action. Then, after 3 months, both groups took part in the posttest. Data was analyzed by paired T-test, independent T-test and chi-square using SPSS-18 software. Results: A significant difference was found between the two groups regarding knowledge, evaluations behavioral outcomes, Behavioral beliefs and intention (P<0.001. Chi-square analysis showed a significant difference between the two groups regarding their performance (P<0.001. Conclusion: The present intervention was effective in increasing the pregnant women’s knowledge, evaluation of outcomes, attitude and strengthening their intention as well as performance. Therefore, it is suggested to use this model and other systematic straining for pregnant women to decrease the rate of cesarean section.

    Background: Caesarean section rates are increasing in Mexico and Latin America. This study evaluates the impact of a large-scale, conditional cash transfer programme in Mexico on caesarean section rates. The programme provides cash transfers to participating low income, rural households in Mexico conditional on accepting health care and nutrition supplements. Methods: The primary analyses uses retrospective reports from 979 women in poor rural communities participating in an effectiveness study and randomly assigned to incorporation into the programme in 1998 or 1999 across seven Mexican states. Using multivariate and instrumental variable analyses, we estimate the impact of the programme on caesarean sections and predict the adjusted mean rates by clinical setting. Programme participation is measured by beneficiary status, programme months and cash transfers. Results: More than two-thirds of poor rural women delivered in a health facility. Beneficiary status is associated with a 5.1 percentage point increase in caesarean rates; this impact increases to 7.5 percentage points for beneficiaries enrolled in the programme for ≥6 months before delivery. Beneficiaries had significantly higher caesarean delivery rates in social security facilities (24.0 compared with 5.6% among non-beneficiaries) and in other government facilities (19.3 compared with 9.5%). Conclusion: The Oportunidades conditional cash transfer programme is associated with higher caesarean section rates in social security and government health facilities. This effect appears to be driven by the increases in disposable income from the cash transfer. These findings are relevant to other countries implementing conditional cash transfer programmes and health care requirements. PMID:19933778

    Full Text Available Background: The rate of primary cesarean section (CS is on the rise. More and more women report with a history of a previous CS. A trial of vaginal delivery can save these women from the risk of repeat CS. Aims: The study was conducted to assess the safety and success rate of vaginal birth after CS (VBAC in selected cases of one previous lower segment CS (LSCS. Materials and Methods: The prospective observational study was carried out in a tertiary care teaching hospital over a period of two years. One hundred pregnant women with a history of one previous LSCS were enrolled in the study. Results: In the present study, 85% cases had a successful VBAC and 15% underwent a repeat emergency LSCS for failed trial of vaginal delivery. Cervical dilatation of more than 3 cm at the time of admission was a significant factor in favor of a successful VBAC. Birth weight of more than 3,000 g was associated with a lower success rate of VBAC. The incidence of scar dehiscence was 2% in the present study. There was no maternal or neonatal mortality. Conclusion: Trial of VBAC in selected cases has great importance in the present era of the rising rate of primary CS especially in rural areas.

    Full Text Available Background/Aim. Maternal morbidity is defined as any condition that is attributed to or aggravated by pregnancy and childbirth that has a negative impact on the woman's wellbeing. In recent years, a growing trend of cesarean section rates can be seen throughout the world. The aim of this study was to assess factors that might have major impact on maternal adverse outcome in women with two or more previous cesarean sections. Methods. This retrospective study included women with single term pregnancy after two or more cesarean deliveries in a 10-year period (2004−2013 in the University Clinic “Narodni front” in Belgrade, Serbia. Medical records were reviewed for clinical data for maternal intraoperative and early postoperative complications regarding gestational age at delivery, the number of previous cesarean sections and mode of surgery (elective or emergency. Results. A total of 551 patients were included in the study. At 37 completed weeks delivered 14.1%, at 38 delivered 45.2% and at 39 completed weeks 40.7% patients. Women younger than 35 years more often delivered after 39 completed weeks compared with those over 35 years (69.2% vs 30.8%, p < 0.05. The overall rate of maternal complications in the study group was 16.5% with no statistical difference by gestational age at delivery. The overall rate of maternal adverse outcome was significantly less in the patients with three as compared with those with four or more cesareans (10.4% vs 66.7%, p < 0.05. There was a statistically significant difference between these groups of women regarding complications: scar dehiscence, the presence of adhesions, blood transfusion and admission in intensive care unit. Elective cesarean delivery was with less maternal complications compared with emergency cesarean deliveries (12.9% vs 27.3%, p < 0.05. Conclusion. Termination of pregnancy before completed 39 weeks does not decrease maternal morbidity. The major impact on maternal complications has the

    Full Text Available Patients with Klippel-Feil Syndrome (KFS have congenital fusion of their cervical vertebrae due to a failure in the normal segmentation of the cervical vertebrae during the early weeks of gestation and also have myriad of other associated anomalies. Because of limited neck mobility, airway management in these patients can be a challenge for the anesthesiologist. We describe a unique case in which a dexmedetomidine infusion was used as sedation for an awake fiber-optic intubation in a parturient with Klippel-Feil Syndrome, who presented for elective cesarean delivery. A 36-yearold female, G2P1A0 with KFS (fusion of cervical vertebrae who had prior cesarean section for breech presentation with difficult airway management was scheduled for repeat cesarean delivery. After obtaining an informed consent, patient was taken in the operating room and non-invasive monitors were applied. Dexmedetomidine infusion was started and after adequate sedation, an awake fiberoptic intubation was performed. General anesthetic was administered after intubation and dexmedetomidine infusion was continued on maintenance dose until extubation. Klippel-Feil Syndrome (KFS is a rare congenital disorder for which the true incidence is unknown, which makes it even rare to see a parturient with this disease. Patients with KFS usually have other congenital abnormalities as well, sometimes including the whole thoraco-lumbar spine (Type III precluding the use of neuraxial anesthesia for these patients. Obstetric patients with KFS can present unique challenges in administering anesthesia and analgesia, primarily as it relates to the airway and dexmedetomidine infusion has shown promising result to manage the airway through awake fiberoptic intubation without any adverse effects on mother and fetus.

To assess the risk of classical hysterotomy and surgical morbidity among women with a body mass index (BMI greater than 40 kg/m2 who underwent a supraumbilical incision at the time of cesarean delivery. Methods. We conducted a retrospective cohort study in women having a BMI greater than 40 kg/m2 who underwent a cesarean delivery of a live, singleton pregnancy from 2007 to 2011 at a single tertiary care institution. Intraoperative and postoperative outcomes were compared between patients undergoing supraumbilical vertical (cohort, or Pfannenstiel (controls, skin incisions. Results. Women undergoing supraumbilical incisions had a higher risk of classical hysterotomy (OR, 24.6; 95% CI, 9.0–66.8, surgical drain placement (OR, 6.5; 95% CI, 2.6–16.2, estimated blood loss greater than 1 liter (OR, 3.4; 95% CI, 1.4–8.4, and longer operative time (97 ± 38 minutes versus 68 ± 30 minutes; when compared to subjects with Pfannenstiel incisions (controls. There was no difference in the risk of wound complication between women undergoing supraumbilical or Pfannenstiel incisions (OR, 2.7; 95% CI, 0.9–8.0. Conclusion. In women with a BMI above 40 kg/m2, supraumbilical incision at the time of cesarean delivery is associated with a greater risk of classical hysterotomy and operative morbidity.

    Oxytocin is routinely used as prophylaxis against uterine atony. During elective cesarean delivery (CD), an oxytocin bolus is used to initiate adequate uterine tone, followed by an oxytocin infusion to maintain uterine contractility. However, it is unclear whether oxytocin maintenance infusion rate influences total estimated blood loss (EBL). We performed a prospective, randomized, double-blind trial in 51 women undergoing elective CD. Women were randomly assigned to receive an oxytocin maintenance infusion of 2.5 or 15 U/h. All women received an oxytocin 1 U bolus to initiate adequate uterine tone. The primary outcome was EBL. EBL values between groups were compared using a Mann-Whitney U test; P EBL difference with 95% confidence intervals was also calculated. Secondary outcomes included adequacy of uterine tone, use of additional uterotonics, and oxytocin-related side effects, including hypotension. Of 51 women, 24 received a low-rate infusion and 27 received a high-rate infusion. Median (interquartile range) EBL values in the low-rate and high-rate groups were 634 (340-886) mL versus 512 (405-740) mL, respectively (P = .7). The median difference in EBL between groups was 22 mL; 95% confidence interval = -158 to 236 mL. The rate of postpartum hemorrhage did not differ between groups (low-rate group: 4/24 [16.7%] versus high-rate group: 4/26 [15.4%]). There were no between-group differences over time (first 20 minutes after commencing infusion) in the incidence of adequate uterine tone (P = .72) or hypotension (P = .32). Among women undergoing elective CD receiving an oxytocin maintenance infusion, EBL and uterine tone did not differ between women receiving 2.5 U/h oxytocin and those receiving 15 U/h oxytocin. Our findings suggest that efficacy can be obtained with a low oxytocin maintenance infusion rate; however, dose-finding studies are needed to determine the infusion rate that optimizes drug efficacy while minimizing side effects.

    Objective: To explore the outcome of trial of labor after cesarean section(TOLAC). Methods: Totally 614 TOLAC were conducted in the First Affiliated Hospital of Kunming Medical University from July 2013 to June 2016. Among them, 586 cases of singleton pregnancy with one prior cesarean section(gestational age≥28 weeks)were studied retrospectively. The maternal and neonatal outcomes among the vaginal birth after cesarean(VBAC)group(481 cases), failed TOLAC group(105 cases)and the elective repeat cesarean section(ERCS)group(1 145 cases)were compared. Multiple logistic regression was used to determine the risk factors of admission to neonatal intensive care unit(NICU). Results: (1)The TOLAC rate was 29.62%(614/2 073)from July 2013 to June 2016, and the VBAC rate was 82.6%(507/614). The cesarean section rate was reduced by VBAC by 3.147%(507/16 112).(2)The comparison of adverse maternal outcomes: in the VBAC group, the postpartum hemorrhage volume was(431±299)ml, the rate of postpartum fever was 6.4%(31/481), the birth weight of the neonates was(3 085± 561)g, and the rate of large for gestational age was 2.9%(14/481). All were significantly lower than those in the failed TOLAC group and the ERCS group(P0.05). Multiple logistic regression showed no association between VBAC and admission to the NICU(OR=0.84, 95%CI: 0.58-1.21). The isolated risk factors for admission to the NICU were preterm birth(OR=16.71, 95% CI: 11.44-24.40), hypertensive disorder complicating pregnamcy(OR=3.89, 95% CI: 2.39-6.35), meconium stained amniotic fluid(OR=2.48, 95% CI: 1.62-3.80), small for gestational age(OR=2.00, 95% CI: 1.19-3.36)and diabetes mellitus(OR=1.69, 95% CI: 1.14-2.50). Conclusions: VBAC reduces cesarean section rate, with good outcomes in both mother and neonate. It is a safe and feasible way of labor in women with only one cesarean section history.

    in the vital statistics the cesarean section is a cause that makes reference to births and deaths. to analyze the frequency of the cesarean section, the changes brought about in the rates of maternal, perinatal mortality and of natality, and their relation with reliable contraceptive methods. retrospective study realized with the dices of patients of the Coordination of Reproductive Health of the Mexican Institute of the Social Insurance (IMSS) of the state of Aguascalientes (Mexico). The births were registered majors of 20 weeks of gestation, the maternal and perinatal deaths from 1990 to 2007 in the hospitals of the IMSS in Aguascalientes. The rate of cesarean calculated by means of the registry of the number of the same realized per year and they were divided between the total of vaginal and abdominal births, and the result multiplied percent. 201,563 obstetrical events were registered, of which 145,106 corresponded to vaginal childbirths and 56,457 abdominal ones. With these data a global rate of cesarean section of 28% was obtained, with 201,182 new born alive ones and 2,618 perinatal ones. The acceptance of the tubary bilateral occlusion maintained a constant increase during the period of study, like the intrauterine device. The acceptance from the bilateral occlusion was completely different tubary during the cesarean one, in comparison with the childbirth. the long term results show positive influence in the reduction of the rate of natality.

    Because of the main justification for practicing a cesarean section is due to a previous cesarean and the rasing rates frequency of this operation, we concluded a descriptive and prospective investigation in order to analize the factibility and security of vaginal delivery after one cesarean section. We include 1000 patients with a past history of one previous cesarean section and with the following main characteristics: normal evaluation of the actual pregnancy and a gestational age of at least 36 weeks of pregnancy, no pelvis stenosis and a normal fetal status. The management were expectant and or with the use of oxitocin, prostaglandin PGEJ, uterionhibition and or amnioinfusion according to medical indication, 679 (67.9%) patients had a vaginal delivery; one ruterine rupture (0.001 x 1000) happened (the place of the rupture were not in the scar of the previous cesarean); two uterine dehicence (0.002 x 1000) of the previous uterine scar; one of this require laparotomy and sture of the dehiscence scar and the other one only require observation. We had two intrapartum fetal dead (0.002 x 1000) on due to the uterine rupture and the other one because of a taquisitolia not corrected by betamimetics. The factibility and security of vaginal delivery after one previous cesarean section is a logical and reasonable strategy in order to decrease the actual high rates of cesarean section. Whenever we try a viginal delivery in a patients with one previous cesarean is imperative to keep in mind that if something is not going well during the attempts we must repeat another cesarean.

    Summary Background The number of incoming expectant women who have previously experienced cesarean section has increased. This work sought to find the frequency and connections between vaginal deliveries, cesarean sections, and iterative cesarean sections from 2004 to 2008. Material/Methods In all, 828 women with previous cesarean sections were included. From this group, 8282 vaginal deliveries were performed. During these years, 828 women had a history of the cesarean section; in these women, iterative cesarean sections were indicated. To evaluate knowledge of educational material designed for women being prepared for the iterative delivery, we used information compiled on experience from 2002 to 2003; the same approach was used to evaluate the nursing process on interventions and diagnoses of cesarean sections. Results From 2004 to 2008, 11 279 deliveries were performed in the Perinatological Center in České Budějovice; this was significant (Pcesarean section. The number of iterative cesarean sections in women who had already experienced the cesarean section (828) and delivered by cesarean section again is 620. Other data were not significant. Only 2 to 3 pregnancies next to the first cesarean section were statistically significant in 2004 and 2005. Conclusions If a trial of labor after cesarean does not proceed to vaginal birth, the woman will need support and encouragement to express feelings about another cesarean birth. PMID:21278695

    The tendency of increasing cesarean section rate has drawn worldwide attention. The vaginal birth after cesarean section is a useful method to decrease cesarean section rate at defined cases. Retrospective overview of factors resulting successful vaginal birth, labor/induction's condition, criterias, short and long term benefits and consequences. Overview recommendations of international guidelines and publications' results concerned vaginal birth after cesarean section in "PubMed", "MEDLINE", "Cochrane" databases from 1996 to 2016. Reviewing results of recommendations and publications we can declare that statements are inconsistent, however the option of vaginal birth after cesarean section is appropriate for decrease complications and trend of increasing cesarean section rate. It would be important in our country to define a uniform recommendation regarding vaginal birth after cesarean section, with supporting evidence in obstetrical and gynecological practice.

    This study explored the effects of the diagnosis-related group (DRG)-based prospective payment system (PPS) operated by voluntarily participating organizations on the cesarean section (CS) rates, and analyzed whether the participating health care organizations had similar CS rates despite the varied participation periods. The study sample included delivery claims data from the Korean national health insurance program for the year 2003. Risk factors were identified and used in the adjustment model to distinguish the main reason for CS. Their risk-adjusted CS rates were compared by the reimbursement methods, and the organizations' internal and external environments were controlled. The final risk-adjustment model for the CS rates meets the criteria for an effective model. There were no significant differences of CS rates between providers in the DRG and fee-for-service system after controlling for organizational variables. The CS rates did not vary significantly depending on the providers' DRG participation periods. The results provide evidence that the DRG payment system operated by volunteering health care organizations had no impact on the CS rates, which can lower the quality of care. Although the providers joined the DRG system in different years, there were no differences in the CS rates among the DRG providers. These results support the future expansion of the DRG-based PPS plan to all health care services in Korea.

    Full Text Available (Received 8 April, 2009 ; Accepted 27 May, 2009AbstractBackground and purpose: Radiographic film repeat rate assessment is performed to appropriate profiting of existence resources in therapeutic wards. Multiple exposures of x-ray generators due to repeated radiographic examination can lead to amortization of the radiographic facilities and decrease their longevity and also increases the cost of facilities repair. On the other hand, its therapeutic services are necessary to be carried out for patients as soon as possible. Recognition of radiographic film repeat rate and its related causes will help to eliminate the problems and are cost effective.Materials and methods: In this descriptive study, samples were garnered with data collection and non random model during three months in eight radiographic rooms and four darkrooms belonging to four governmental hospitals, namely Imam Khomeini, Booali Sina, Fatemh Zahra and Zare in Sari. All rejected radiographic films were seen by resident experts in each center and information was entered into designed forms. Radiographic repeat rates were calculated through data available from all recipients and the number of used films. In this article, related causes responsible for repeated radiographic examination including errors in selection of exposure factors (over exposure and under exposure, positioning, centering, film size, equipment, processing or darkroom, movement and others were assessed.Results: In four hospitals, 36,758 films were received during investigation and the number of repeated films was 2,155 (5.9 % were estimated as radiographic repeat rate. The maximum repeat rate belonged to Booali sina Hospital (7.2 % and the minimum one was Zare Hospital (0.7 %. The most important causes were due to over exposure selection (1.4 % and the least one was due to improper selection of film size (0.08 %. The percentage of other factors include, under exposure selection (1.12%, centering (0.92%, others (0

    The study aim was to evaluate management of myomas during cesarean section, the pro and cons and the outcomes of cesarean myomectomy. Moreover, we tried to investigate the long-term outcomes of cesarean myomectomy. The authors conducted a literature review using scientific databases, focusing on the benefits and outcomes of cesarean myomectomy and the recent trends regarding this topic, and identified relevant articles, related references and other papers citing them. Despite the demonstrated advantages of cesarean myomectomy, postponed myomectomy after cesarean section was recommended in some instances. Apart from recent reports on the safety and feasibility of cesarean myomectomy, the current literature also describes serious complications of cesarean myomectomy, including even maternal death. This poses a question about the reported rate of complications: whether it is underestimated in common practice. Although some studies strongly suggest the safety of cesarean myomectomy, data on the long-term outcomes of cesarean myomectomy in women are lacking. The risk-benefit ratio of cesarean myomectomy should be re-evaluated in the new century, given the increasing patient age, incidence of myoma in pregnancy, and the wide use of assisted reproductive techniques. © 2017 Japan Society of Obstetrics and Gynecology.

    To examine the effect of maternal age on indication for primary cesarean delivery in low-risk nulliparous women. Retrospective cohort study. Urban academic tertiary care center. Nulliparous women younger than 35 years of age delivering vertex-presenting singletons at term. Participants underwent spontaneous, operative or cesarean delivery. Mode of delivery, indication, and timing of cesarean delivery. Adolescents were half as likely to undergo cesarean delivery overall (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.43-0.54), and more than one-third less likely to undergo cesarean delivery in labor (OR, 0.59; 95% CI, 0.53-0.66). Adjustment for potential confounders did not alter the strength of these associations. Adolescents were half as likely to undergo cesarean delivery for failure to progress (OR, 0.49; 95% CI, 0.43-0.54). There was no difference in the odds of cesarean delivery for nonreassuring fetal status (OR, 0.91; 95% CI, 0.77-1.06), or genital herpes (OR, 1.44; 95% CI, 0.57-3.68). Induction, macrosomia, oxytocin augmentation, and any labor complication were all associated with increased risk of cesarean delivery. There was no difference in the duration of second stage for adolescents who delivered by cesarean delivery compared with adults (240.0 vs 237.7 minutes; P = .84), but adolescents who delivered vaginally had a second stage that was one-third shorter than adults (62.5 vs 100.3 minutes; P cesarean delivery overall, and 40% less likely to undergo a primary cesarean delivery in labor, even after adjustment for multiple maternal, neonatal, and labor characteristics.

    Full Text Available Wael Naeem Thabet1, Ahmad Samir Hossny1, Nadine Alaa Sherif21Department of General Surgery, 2Department of Obstetrics and Gynecology, Cairo University, Cairo, EgyptAbstract: Abdominoplasty is an esthetic surgical procedure that restores abdominal contouring. Repeated pregnancies combined with advancing maternal age usually lead to lower abdominal skin redundancy and excess fat accumulation. Delivery via Cesarean section adds weakness to the lower abdominal wall muscles and yields a lower transverse Cesarean scar. Some patients request whether abdominoplasty can be performed with Cesarean section in the same setting, to avoid a future surgery. This study was designed to evaluate the outcome of combined abdominoplasty with Cesarean section. The study included 50 pregnant women from September 2009 to June 2010 with an average follow-up period of 9 months. Nine patients (18% developed wound infection; three of them (6% developed wound dehiscence. Six patients (12% developed lower abdominal skin necrosis; three of them (6% were treated conservatively and healed by secondary intention, while surgical debridement and secondary sutures were needed in the other three patients (6%. Residual abdominal skin redundancy in nine patients (18%, outward bulging of the abdomen and lack of waist definition in 16 patients (32%, and outward bulging of the umbilicus in twelve patients (24% were the reported unesthetic results. The results were compared with results of 80 abdominoplasties in nonpregnant women.Keywords: abdominoplasty, Cesarean section, pregnancy

    Introduction Perinatal mortality rates have come down in cesarean sections, but fetal morbidity is still high in comparison to vaginal delivery and the complications are more commonly seen in emergency than in elective cesarean sections. The objective of the study was to compare the fetal outcome and the indications in elective versus emergency cesarean section performed in a tertiary maternity hospital. Methods This comparative cross-sectional prospective study of all the cases undergoing elective and emergency cesarean section for any indication at Souissi maternity hospital of Rabat, Morocco, was carried from January 1, to February 28, 2014. Data were analyzed with emphasis on fetal outcome and cesarean sections indications. Mothers who had definite antenatal complications that would adversely affect fetal outcome were excluded from the study. Results There was 588 (17.83%) cesarean sections among 3297 births of which emergency cesarean section accounted for 446 (75.85%) and elective cesarean section for 142 cases (24.15%). Of the various factors analyzed in relation to the two types of cesarean sections, statistically significant associations were found between emergency cesarean section and younger mothers (P cesarean section performed under general anesthesia (P cesarean section was fetal distress (30.49%), while the most frequent indication in elective cesarean section was previous cesarean delivery (47.18%). Conclusion The overall fetal complications rate was higher in emergency cesarean section than in elective cesarean section. Early recognition and referral of mothers who are likely to undergo cesarean section may reduce the incidence of emergency cesarean sections and thus decrease fetal complications. PMID:27347286

    2015-01-01

    The thickness and density of the Antarctic firn layer vary considerably in time and space, thereby contributing to ice-sheet volume and mass changes. Distinguishing between these mass and volume changes is important for ice-sheet mass-balance studies. Evolution of firn layer depth and density is often modeled, because direct measurements are scarce. Here we directly compare modeled firn compaction rates with observed rates obtained from repeat-track airborne radar data over a 2 year interval ...

  6. Interaction of small repeating earthquakes in a rate and state fault model

    2010-12-01

    Small repeating earthquake sequences can be located very close, for example, the San Andreas Fault Observatory at Depth (SAFOD) target cluster repeaters "San Francisco" and "Los Angeles" are separated by only about 50 m. These two repeating sequences also show closeness in occurrence time, indicating substantial interaction. Modeling of the interaction of repeating sequences and comparing the modeling results with observations would help us understand the physics of fault slip. Here we conduct numerical simulations of two asperities in a rate and state fault model (Chen and Lapusta, JGR, 2009), with asperities being rate weakening and the rest of the fault being rate-strengthening. One of our goals is to create a model for the observed interaction between "San Francisco" and "Los Angeles" clusters. The study of Chen and Lapusta (JGR, 2009) and Chen et al (accepted by EPSL, 2010) showed that this approach can reproduce behavior of isolated repeating earthquake sequences, in particular, the scaling of their moment versus recurrence time and the response to accelerated postseismic creep. In this work, we investigate the effect of distance between asperities and asperity size on the interaction, in terms of occurrence time, seismic moment and rupture pattern. The fault is governed by the aging version of rate-and-state friction. To account for relatively high stress drops inferred seismically for Parkfield SAFOD target earthquakes (Dreger et al, 2007), we also conduct simulations that include enhanced dynamic weakening during seismic events. As expected based on prior studies (e.g., Kato, JGR, 2004; Kaneko et al., Nature Geoscience, 2010), the two asperities act like one asperity if they are close enough, and they behave like isolated asperities when they are sufficiently separated. Motivated by the SAFOD target repeaters that rupture separately but show evidence of interaction, we concentrate on the intermediate distance between asperities. In that regime, the

  8. Delivery after previous cesarean: Short-term perinatal outcomes

    2010-01-01

    Women must often choose between a vaginal birth after prior cesarean and elective repeat cesarean delivery. Short-term risks of vaginal birth after cesarean can be potentially catastrophic in the setting of uterine rupture. Although randomized controlled trials comparing these two modes of delivery are lacking, observational studies suggest an increased risk of perinatal mortality and hypoxic-ischemic encephalopathy in infants whose mothers undergo a trial of labor. These rare risks compete with more common, albeit less severe, short-term risks associated with elective repeat cesarean delivery with a particular emphasis on increased respiratory morbidities. Further studies are needed to identify potential strategies to improve perinatal outcomes and help guide physicians and patients in choosing optimal methods of delivery. PMID:20654778

    Repeating earthquakes, the sequence of stress accumulation and release at isolated small asperities on a plate interface, can be regarded as a renewal process in statistics. From such a point of view, we modelled a sequence of repeating earthquakes and developed an objective Bayesian method to estimate the space-time distribution of interplate slip rates from the recurrence intervals of repeating earthquakes. The space-time distribution of slip rates is represented by the superposition of tri-cubic B-splines. The knots of B-splines in time are unequally allocated for representing co-seismic abrupt and post-seismic rapid changes in slip rates. In addition, to avoid overfitting, smoothness constraints are imposed and their optimal weights are determined by Akaike's Bayesian Information Criterion. We applied this method to the complete data set of repeating earthquakes in northeast Japan for about 18 yr before the 2011 Tohoku-oki earthquake, and revealed spatiotemporal variations of interplate slip rates off the Hokkaido-Tohoku region, where the 1994 Sanriku-oki (M7.6), 2003 Tokachi-oki (M8.0), 2004 Kushiro-oki (M7.1), and 2008 Ibaraki-oki (M7.0) earthquakes occurred. First, we confirmed the reciprocal correlation between the spatial distribution of average slip rates for a seismically calm period (1996-2000) and that of average slip-deficit rates, which has been estimated from GPS array data. Then, we examined the temporal variations of slip rates associated with the large interplate earthquakes in detail.

    The cesarean rates are low but increasing in most Nordic countries. Using the Robson classification, we analyzed which obstetric groups have contributed to the changes in the cesarean rates. Retrospective population-based registry study including all deliveries (3 398 586) between 2000 and 2011 in Denmark, Finland, Iceland, Norway and Sweden. The Robson group distribution, cesarean rate and contribution of each Robson group were analyzed nationally for four 3-year time periods. For each country, we analyzed which groups contributed to the change in the total cesarean rate. Between the first and the last time period studied, the total cesarean rates increased in Denmark (16.4 to 20.7%), Norway (14.4 to 16.5%) and Sweden (15.5 to 17.1%), but towards the end of our study, the cesarean rates stabilized or even decreased. The increase was explained mainly by increases in the absolute contribution from R5 (women with previous cesarean) and R2a (induced labor on nulliparous). In Finland, the cesarean rate decreased slightly (16.5 to 16.2%) mainly due to decrease among R5 and R6-R7 (breech presentation, nulliparous/multiparous). In Iceland, the cesarean rate decreased in all parturient groups (17.6 to 15.3%), most essentially among nulliparous women despite the increased induction rates. The increased total cesarean rates in the Nordic countries are explained by increased cesarean rates among nulliparous women, and by an increased percentage of women with previous cesarean. Meanwhile, induction rates on nulliparous increased significantly, but the impact on the total cesarean rate was unclear. The Robson classification facilitates benchmarking and targeting efforts for lowering the cesarean rates. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

  16. Hysteroscopy and suction evacuation of cesarean scar pregnancies: a case report and review.

    Science.gov (United States)

    Fylstra, Donald L

    2014-03-01

    Implantation of a pregnancy into the scar of a prior cesarean is an uncommon type of ectopic pregnancy. The incidence of cesarean scar pregnancy is thought to be one in 1800-2216 pregnancies. The increase in the incidence of cesarean scar pregnancy is thought to be a consequence of the increasing rates of cesarean delivery. The natural history of cesarean scar pregnancy is unknown. However, if such a pregnancy is allowed to continue, uterine scar rupture with hemorrhage and possible hysterectomy seem likely. Two early diagnosed cesarean scar pregnancies were treated with hysteroscopy and suction curettage removal. One required intramuscular methotrexate to resolve a persistent cesarean scar ectopic pregnancy. It would seem reasonable that simple suction evacuation would frequently leave chorionic villi imbedded within the cesarean scar, as the pregnancy is not within the endometrial cavity.

    Full Text Available Cesarean section must be justified only when benefits outweigh harm to the mother and fetus. The impact of Cesarean section on maternal and child health and its high cost compared with vaginal birth represent a public health problem. Cesarean section rate is increasing globally and reported to be 25 - 30% in recent studies . Several factors contribute to this increase , but repeat CS stands as the most relevant factor and contribute to about 29% of performed CS. One of the strategies proposed to reduce the CS rate is to increase the number of trials of labor among women who had previous one lower segment cesarean section. However , concern still remains r egarding associated maternal or neonatal complications and factors that lead to success or failure of VBAC. So , we undertook this study to evaluate the factors affecting success of VBAC. AIMS AND OBJECTIVE: To study maternal and fetal outcomes associated w ith trial of vaginal birth after cesarean section and to evaluate factors associated with its success. MATERIALS AND METHODS : It is an Observational prospective study performed on 100 partu rients in the department of OBG, in Mamata General Hospital , K hammam , Andhra Pradesh. Patients with previous one lower segment Cesarean section and a single fetus with cephalic presentation without cephalo - pelvic disproportion were included in the study. These women were given a trial for vaginal birth with observati on during labor by a partogram and external fetal cardiotocography. RESULTS: Vaginal birth was successful in 50%. Repeat Cesarean section was done in the other 50% due to suspicious scar (62% , fetal distress (24% and failure to progress (14%. Scar Ruptu re occurred in (6% , postpartum hemorrhage in (4% , neonatal incubation in (10% and the neonatal mortality was (2%. Vaginal birth was significantly higher in the age group 20 - 30 years , body mass index in between 20 - 25 , patients with prior vaginal birth , inter - pregnancy interval

    Full Text Available A project was planned to study some physical characteristics of oestrus mucus and conception rates in repeat breeder buffaloes after different treatments. For this purpose 60 adult buffaloes with history of repeat breeding were used. Mucus samples from these animals were collected during heat and studied for colour, consistence, pH and fern pattern. Experimental buffaloes were randomly divided into four equal groups A, B, C and D. In buffa1oes of group A, GnRH was given immediately after insemination. In group B antibiotic infusion was given 24 hr after insemination. In animals of group C, insemination was done in the uterine horn ipsilateral to ovary bearing mature graafian follicle. Animals of group D were inseminated in the uterine body and served as control. The results indicated that oestrus mucus was transparent in 55.0%, translucent in 38.33% and whitish in 6.67% buffaloes. The consistency of mucus was viscous in 38.33%, thin in 50.0% and thick in, 11.67% repeat breeder buffaloes. Mean pH of oestrus mucus was 7.49 ± 0.35. Fren pattern was very characteristic in 6.67% characteristic in 48.33% and less characteristic in 45.0% buffaloes. The conception rates in animals of group B were significantly higher ( P<0.05 than those of group A, C or D; the differences in conception rates among buffaloes of the latter three groups were non significant. It was concluded that post-insemination antibiotic infusion may be used to improve conception rates in repeat breeder buffaloes.

    The aim of the present study was to examine the effect of an 8-week endurance training program on repeated-sprint (RS) performance and post-sprints muscle reoxygenation rate in 18 moderately trained males (34 ± 5 years). Maximal aerobic speed (MAS), 10 km running and RS (2 × 15-s shuttle-sprints, interspersed with 15 s of passive recovery) performance were assessed before and after the training intervention. Total distance covered (TD) and the percentage of distance decrement (%Dec) were calculated for RS. Between-sprints muscle reoxygenation rate (Reoxy rate) was assessed with near-infrared spectroscopy during RS before and after training. After training, MAS (+9.8 ± 5.8%, with 100% chances to observe a substantial improvement), 10 km time (-6.2 ± 5.3%, 99%), TD (+9.6 ± 7.7%, 98%), %Dec (-25.6 ± 73.6%, 93%) and Reoxy rate (+152.4 ± 308.1%, 95%) were improved. The improvement of Reoxy rate was largely correlated with improvements in MAS [r = 0.63 (90% CL, 0.31;-0.82)] and %Dec [r = -0.52 (-0.15;-0.76)]. Present findings confirm the beneficial effect of endurance training on post-sprint muscle reoxygenation rate, which is likely to participate in the improvement of repeated-sprint ability after training. These data also confirm the importance of aerobic conditioning in sports, where repeating high-intensity/maximal efforts within a short time-period are required.

    Full Text Available Com objetivo de investigar associações entre fatores socioeconômicos e complicações da cesariana, uma amostra de 604 puérperas cujos partos ocorreram em duas maternidades no Sul do Brasil foi entrevistada 24 horas pós-parto e na segunda semana do puerpério, por meio de entrevistas hospitalares e domicilio. Regressão de Cox foi aplicada ao modelo hierárquico dos fatores associados ao tipo de parto e às complicações no pós-parto. Complicações foram duas vezes mais frequentes após cesariana, independentemente das condições socioeconômicas. Contudo, a maneira como o parto cesáreo se associou ao risco de complicações mostrou-se mediada pelas circunstâncias socioeconômicas representadas pela categoria do pré-natal e parto, ter ou não o mesmo profissional no pré-natal e parto e ter sua cesariana decidida intraparto. Resultados do estudo evidenciam que complicações pós-cirúrgicas da cesariana têm impacto adverso, principalmente, entre aquelas mulheres vivendo em condições sociais e de saúde menos privilegiadas, as quais, após o parto, retornam para um ambiente de menor suporte, com uma cicatriz abdominal.This study focused on the association between social factors and complications following cesarean sections. A sample of 604 women delivering in the two main maternity hospitals in a city in southern Brazil were interviewed 24 hours after delivery and two weeks postpartum, using in-hospital and home interviews. Cox regression was applied, using a hierarchical framework of factors associated with post-cesarean complications. Post-partum complications were twice as frequent after cesareans as compared to vaginal delivery, independently of socioeconomic conditions. However, the increased the risk of complications associated with cesarean section proved to be mediated by socioeconomic circumstances, as represented by prenatal and childbirth care in the public health system, not having the same physician throughout

  1. Women's preference for cesarean delivery and differences between Taiwanese women undergoing different modes of delivery

    2010-01-01

    Background The rate of cesarean delivery was 35% in 2007 in Taiwan. It is unclear how many of the cesarean deliveries were without medical indications. Women's preference for cesarean delivery during their course of pregnancy has rarely been studied and therefore our objectives were to examine rate of cesarean deliveries without medical indications, to explore women's preference for cesarean delivery as their gestation advances, and to compare background and perinatal factors among women who underwent different modes of delivery in Taiwan. Methods This prospective study applied a longitudinal design. The study participants were 473 women who received prenatal care at four hospitals in Taipei and answered structured questionnaires at 20 to 24 weeks of pregnancy, 34 to 36 weeks of pregnancy, and 5 to 7 weeks after delivery. Results Of the 151 women (31.9%) who had cesarean deliveries, 19.9% were without medical indication. Three indications: malpresentation, prior cesarean section, and dysfunctional labor together accounted for 82.6% of cesarean section with medical indications. The prevalence of maternal preference for cesarean delivery was found to be 12.5% and 17.5% during the second and third trimester, respectively. Of the women who preferred cesarean delivery during the second trimester, 93.2% eventually had a cesarean delivery. Women who were older, with older spouses, and who had health problems before or during pregnancy were more likely to have cesarean deliveries. Conclusions About 20% of cesarean deliveries were without medical indications. Women's preference for cesarean delivery during the second trimester predicts subsequent cesarean delivery. Counseling regarding mode of delivery should be offered early in pregnancy, especially for women who are older or with older spouses, have health problems, or had a prior cesarean section.

    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.

    The analysis of heart rate fluctuations, or heart rate variability (HRV), may be applied to explore children's neurodevelopment. However, previous studies have reported poor reliability (repeatability) of HRV measures in children at rest and during light exercise. Whether the reliability can be improved by controlling variables such as physical activity, breathing rate and tidal volume, or by selecting non-conventional techniques for analysing the data remains as an open question. We evaluated the short-term repeatability of RR-interval data from medicated children with congenital hypothyroidism (CH). The alpha(1) exponents, obtained by detrended fluctuation analysis (DFA), from the data of 21 children collected at two different sessions were compared. Elapsed days between sessions were 59 +/- 33, and data were obtained during 10 min, trying to restrict the children's activity while being seated. We found statistical agreement between the means of alpha(1) exponents for each session (p = 0.94) and no bias with a low-coefficient variation (9.1%); an intraclass correlation coefficient ri = 0.48 ([0.14 0.72], 95% confidence interval) was also estimated. These findings, which were compared with results obtained by conventional time and frequency techniques, indicate the existence of agreement between the alpha(1) exponents obtained at each session, thereby providing support concerning the repeatability of HRV data as analysed by DFA in children with congenital hypothyroidism. Of particular interest was also the agreement found by using the central frequency of the high-frequency band and the parameter pNN20, both showing better or similar ri than alpha(1) (0.77 [0.57 0.89] and 0.51 [0.17 0.74], respectively), yet considerably better repeatability than other conventional time and frequency parameters.

    Full Text Available Pregnancy implantation to the cesarean scar could be the life threatening, although it is a rare event, its ratio increased along with the increasing rate of cesarean delivery. Early diagnosis and treatment may be lifesaving with preserving fertility in these patients. In transvaginal ultrasonography; presence of an empty uterine and cervical cavity, lack of continuity of myometrial setting at the anterior isthmic region and pregnancy implantation to this region should suggest the diagnosis. In this article, we aimed to present a patient with scar ectopic pregnancy with the review of the literature.

  8. High teleportation rates using cold-atom-ensemble-based quantum repeaters with Rydberg blockade

    We present a simplified version of a repeater protocol in a cold neutral-atom ensemble with Rydberg excitations optimized for two-node entanglement generation and describe a protocol for quantum teleportation. Our proposal draws from previous proposals [B. Zhao et al., Phys. Rev. A 81, 052329 (2010), 10.1103/PhysRevA.81.052329; Y. Han et al., Phys. Rev. A 81, 052311 (2010), 10.1103/PhysRevA.81.052311] that described efficient and robust protocols for long-distance entanglement with many nodes. Using realistic experimental values, we predict an entanglement generation rate of ˜25 Hz and a teleportation rate of ˜5 Hz . Our predicted rates match the current state-of-the-art experiments for entanglement generation and teleportation between quantum memories. With improved efficiencies we predict entanglement generation and teleportation rates of ˜7.8 and ˜3.6 kHz, respectively, representing a two-order-of-magnitude improvement over the currently realized values. Cold-atom ensembles with Rydberg excitations are promising candidates for repeater nodes because collective effects in the ensemble can be used to deterministically generate a long-lived ground-state memory which may be efficiently mapped onto a directionally emitted single photon.

    The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/μL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple

    To identify risk factors for bladder injury during cesarean delivery, to let patients and doctors know them and their importance. We conducted a case-control study of women undergoing cesarean delivery at the Instituto Nacional de PerinatologíaIsidro Espinosa de los Reyes between January 2001 and December 2007. Cases were women with bladder injuries at the time of cesarean section. Two controls per case were selected randomly. Medical records were reviewed for clinical and demographic data to compare them. Twenty-one bladder injuries were identified among 24, 057 cesarean sections, (incidence 0.087%), only 19 were analized. Prior cesarean section was more prevalent among cases than controls (63% vs 42% p 0.134), with an OR of 2.35 (95% CI 0.759-7.319), when we take only patients with one cesarea in contrast with no cesarea the OR is 3.75 (95% CI 1.002- 14.07). Statistically significant differences (P values < .05) between cases and controls were found in gestacional age (38.16 vs 37.35 weeks), prior cesareans (42% vs 18%), adhesions (79% vs 5%), Odds ratio of 67.5 (95% CI 11.14- 408), VBAC (31.5 vs 3%), median skin incisión (16% vs 68%), Pfannenstiel (84% vs 32%), blood loss (744cc vs 509cc) and length of surgery 135 vs 58 minutes). No differences were found among age, BMI, prior surgery, labor, premature rupture of membranes, station, chorioamnioitis, induction, uterine incision, timing of delivery, uterine rupture. Prior cesarean section and adhesions are risk factors for bladder injury at the time of repeat cesarean delivery. Elective cesarean delivery is valid but it is duty of physicians to inform patients the risks of it.

  13. Understanding interaction of small repeating earthquakes through models of rate-and-state faults

    Science.gov (United States)

    Chen, T.; Lui, K.; Lapusta, N.

    2012-12-01

    Due to their short recurrence times and known locations, small repeating earthquakes are widely used to study earthquake physics. Some of the repeating sequences are located close to each other and appear to interact. For example, the "San Francisco" (SF) and "Los Angeles" (LA) repeating sequences, which are targets of the San Andreas Fault Observatory at Depth (SAFOD), have a lateral separation of less than 70 m. The LA events tend to occur within 24 hours after the SF events, suggesting a triggering effect. Our goal is to study interaction of repeating earthquakes in the framework of rate-and-state fault models, in which repeating earthquakes occur on velocity-weakening patches embedded into a larger velocity-strengthening fault area. Such models can reproduce behavior of isolated repeating earthquake sequences, in particular, the scaling of their moment versus recurrence time and the response to accelerated postseismic creep (Chen and Lapusta, 2009; Chen et al., 2010). Our studies of the interaction of seismic events on two patches show that a variety of interesting behaviors. As expected based on intuition prior studies (e.g., Kato, JGR, 2004; Kaneko et al., Nature Geoscience, 2010), the two patches behave independently when they are far apart and rupture together if they are next to each other. In the intermediate range of distances, we observe triggering effects, with ruptures on the two patches clustering in time, but also other patterns, including supercycles that alternate between events that rupture a single asperity and events that rupture both asperities at the same time. When triggering occurs, smaller events tend to trigger larger events, since the nucleation of smaller events tends to be more frequent. To overcome such a pattern, and have larger events trigger smaller events as observed for the SF-LA interaction, the patch for the smaller event needs to be of the order of the nucleation size, so that the smaller event has difficulty nucleating by

    Directory of Open Access Journals (Sweden)

    RAPHAEL CÂMARA

    Full Text Available ABSTRACT Cesarean section by maternal request is the one performed on a pregnant woman without medical indication and without contraindication to vaginal delivery. There is great controversy over requested cesarean section. Potential risks include complications in subsequent pregnancies, such as uterine rupture, placenta previa and accreta. Potential benefits of requested cesareans include a lower risk of postpartum hemorrhage in the first cesarean and fewer surgical complications compared with vaginal delivery. Cesarean section by request should never be performed before 39 weeks.

  15. Uterine Closure in Cesarean Delivery: A New Technique

    Full Text Available Fear of scar rupture is one of risks involved in a post caesarean pregnancy. This had led to an increased rate of repeat cesarean delivery in today′s times. Closure of the uterine incision is a key step in cesarean section, and it is imperative that an optimal surgical technique be employed for closing a uterine scar. This technique should be able to withstand the stress of subsequent labor. In the existing techniques of uterine closure, single or double layer, correct approximation of the cut margins, that is, decidua-to-decidua, myometrium to myometrium, serosa to serosa is not guaranteed. Also, there are high chances of inter surgeon variability. It was felt that if a suturing technique which ensures correct approximation of all the layers mentioned above with nil or minimal possibility of inter operator variability existed, there will not be any thinning of lower segment caesarean section (LSCS. Further, a scarred uterus repaired in this manner will be able to withstand the stress of labor in future. We hereby report a new technique for uterine closure devised by us, which incorporates a continuous modified mattress suture technique as a modification of the existing surgical technique of uterine closure.

    Data on complications associated with classic cesarean delivery are conflicting. In extremely preterm cesarean delivery (22 0/7-27 6/7 weeks' gestation), the lower uterine segment is thicker. It is plausible that the rates of maternal complications may not differ between classic and low transverse cesarean. We sought to compare maternal outcomes associated with classic versus low transverse cesarean after stratifying by gestation (23 0/7-27 6/7 and 28 0/7-31 6/7 weeks' gestation). We conducted a multihospital retrospective cohort study of women undergoing cesarean delivery at 23 0/7 to 31 6/7 weeks' gestation from 2005 through 2014. Composite maternal outcome (postpartum hemorrhage, transfusion, endometritis, sepsis, wound infection, deep venous thrombosis/pulmonary embolism, hysterectomy, respiratory complications, and intensive care unit admission) was compared between classic and low transverse cesarean. Outcomes were calculated using multivariable logistic regression models yielding adjusted odds ratios with 95% confidence intervals and adjusted P values controlling for maternal characteristics, emergency cesarean delivery, and comorbidities. Analyses were stratified by gestational age categories (23 0/7-27 6/7 and 28 0/7-31 6/7 weeks' gestation). Of 902 women, 221 (64%) and 91 (16%) underwent classic cesarean between 23 0/7 and 27 6/7 and between 28 0/7 and 31 6/7 weeks' gestation, respectively. There was no increase in maternal complications for classic cesarean versus low transverse cesarean between 23 0/7 and 27 6/7 weeks' gestation. However, between 28 0/7 and 31 6/7 weeks' gestation, classic cesarean was associated with increased risks of the composite maternal outcome (adjusted odds ratio, 1.95; 95% confidence interval, 1.10-3.45), transfusion (adjusted odds ratio, 2.42; 95% confidence interval, 1.06-5.52), endometritis (adjusted odds ratio, 3.23; 95% confidence interval, 1.02-10.21), and intensive care unit admission (adjusted odds ratio, 5.05; 95

    To investigate factors influencing skin incision-to-delivery time (including sub-divisions thereof) and the effect of these surgical intervals on immediate neonatal outcome. A prospective cohort analysis was conducted of all women undergoing cesarean delivery at Tygerberg Hospital, Cape Town, South Africa, from May 24 to November 2, 2010. Three surgical intervals were evaluated: skin incision to myometrium, myometrium to delivery, and skin incision to delivery. Neonatal outcome was assessed by the 5-minute Apgar score. Of 1120 cesarean deliveries recorded during the study period, 77.2% were emergency procedures, which were performed more quickly at all surgical planes (Pdelivery time was significantly extended among repeat procedures (Pdeliveries.

    Importance The likelihood of achieving a live-birth with repeat in-vitro fertilisation (IVF) is unclear, yet treatment is commonly limited to three or four embryo transfers. Objective To determine the live-birth rate per initiated IVF cycle and with repeated cycles. Design, Setting and Participants Prospective study of 156,947 UK women who received 257,398 IVF ovarian stimulation cycles between 2003 and 2010 and were followed until June 2012. Main exposure IVF, with a cycle defined as an episode of ovarian stimulation and all subsequent separate fresh and frozen embryo transfers. Main Outcome(s) Live-birth rate per IVF cycle and the cumulative live-birth rates across all cycles in all women and by age and treatment type. Optimal, prognosis-adjusted and conservative cumulative live-birth rates were estimated, reflecting 0%, 30% and 100% of women discontinuing due to poor prognosis and having a live-birth rate of zero had they continued. Results In all women the live-birth rate for the first cycle was 29.5% (95%CI: 29.3, 29.7). This remained above 20% up to and including the fourth cycle. The cumulative prognosis-adjusted live-birth rate across all cycles continued to increase up to the ninth, with 65.3% (64.8, 65.8) of women achieving a live-birth by the sixth cycle. In women younger than 40 using their own oocytes, the live-birth rate for the first cycle was 32.3% (32.0, 32.5), and remained above 20% up to and including the fourth cycle. Six cycles achieved a cumulative prognosis-adjusted live-birth rate of 68.4% (67.8, 68.9). For women aged 40-42, the live-birth rate for the first cycle was 12.3% (95%CI: 11.8, 12.8), with six cycles achieving a cumulative prognosis-adjusted live-birth rate of 31.5% (29.7, 33.3). For women older than 42 years all rates within each cycle were less than 4%. No age differential was observed among women using donor oocytes. Rates were lower in those with untreated male factor infertility compared to those with any other cause, but

    Mexico has the second-highest prevalence of cesarean deliveries in the Americas, behind Brazil. Having had a previous cesarean delivery is highly predictive of having subsequent cesarean deliveries, yet evidence on the drivers of primary (that is, first-time) cesarean deliveries is sparse. Using 2014 Mexican birth certificate data and performing population-level analyses of data on 600,124 first-time mothers giving birth after at least thirty-seven weeks of gestation, we examined the prevalence and determinants of primary cesarean deliveries. We found a very high prevalence of cesarean deliveries among these women-48.7 percent-and wide variations across insurance coverage types. Enrollees in Seguro Popular, the public health insurance program introduced in 2003 for the previously uninsured and gradually rolled out nationally, had a cesarean rate of 40 percent, while women insured through the Social Security Institute for Civil Servants had a rate of 78 percent. The lower risk of primary cesarean deliveries among Seguro Popular enrollees persisted after adjustment for covariates. Rates of primary cesarean deliveries were particularly high in private birthing facilities for all first-time mothers. Reducing the rate of cesarean deliveries in Mexico will require interventions across types of insurance and birthing facilities and will also require targeted public health messaging.

    With over one-third of pregnancies in the United States being delivered by cesarean and the growing knowledge of morbidities associated with repeat cesarean deliveries, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the Society for Maternal-Fetal Medicine, and the American College of Obstetricians and Gynecologists convened a workshop to address the concept of preventing the first cesarean. The available information on maternal and fetal factors, labor management and induction, and non-medical factors leading to the first cesarean were reviewed as well as the implications of the first cesarean on future reproductive health. Key points were identified to assist with reduction in cesarean rates including that labor induction should be performed primarily for medical indication; if done for non-medical indications, the gestational age should be at least 39 weeks or more and the cervix should be favorable, especially in the nulliparous patient. Review of the current literature demonstrates the importance of adhering to appropriate definitions for failed induction and arrest of labor progress. The diagnosis of “failed induction” should only be made after an adequate attempt. Adequate time for normal latent and active phases of the first stage, and for the second stage, should be allowed, as long as the maternal and fetal conditions permit. The adequate time for each of these stages appears to be longer than traditionally estimated. Operative vaginal delivery is an acceptable birth method when indicated, and can safely prevent cesarean delivery. Given the progressively declining use, it is critical that training and experience in operative vaginal delivery is facilitated and encouraged. When discussing the first cesarean with a patient, counseling should include its effect on future reproductive health. PMID:23090537

    Reducing cesarean deliveries is a major public health goal. The low rate of vaginal birth after cesarean has been attributed largely to a decrease in the likelihood of choosing a trial of labor after cesarean, despite evidence suggesting a majority of women with 1 prior low transverse cesarean are trial of labor after cesarean candidates. Although a number of reasons for this decrease have been explored, it remains unclear how systems issues such as physician call schedules influence delivery approach and mode in this context. The objective of the study was to investigate the relationship between obstetricians' call schedule and obstetric outcomes among women eligible for a trial of labor after cesarean. This is a retrospective cohort study of the likelihood of attempting a trial of labor after cesarean and achieving vaginal birth after cesarean among women with 1 prior low transverse cesarean delivery and a term, cephalic singleton gestation based on the delivering provider's call schedule. Attending obstetrician call schedules were classified as traditional or night float call. Night float call was defined as a schedule in which the provider had clinical responsibilities only for a day or night shift, without other clinical responsibilities before or after the period of responsibility for laboring patients. Call schedules are determined by individual provider groups. Bivariable analyses and random-effects logistic regression were used to examine the relationship between obstetricians' call schedule and the frequency of trial of labor after cesarean. Secondary outcomes including frequency of vaginal birth after cesarean and maternal and neonatal outcomes also were assessed. Of 1502 eligible patients, 556 (37%) were delivered by physicians in a night float call system. A total of 22.6% underwent a trial of labor after cesarean and 12.8% achieved vaginal birth after cesarean; the vaginal birth after cesarean rate for women attempting a trial of labor after cesarean

    Questions about the adaptive importance of metabolic rate can be approached only when measurements of differences between individuals are repeatable. We made daily measurements of CO(2) production, body mass, and food uptake over the adult life span of unmated Vanessa cardui kept under constant environmental conditions in both fed and unfed treatments. Mass and CO(2) production generally declined with age in both treatments, though with much day-to-day variability in the fed treatment. For the full samples, metabolic rate was repeatable for the unfed treatment (repeatability r = 0.60) but not for the fed treatment (r = 0.03). Differences between fed and unfed individuals of the same age range were repeatable for the unfed treatment (r = 0.39) but not for the fed treatment (r = -0.20). Removing age effects on CO(2) production yielded still higher repeatability in the unfed treatment (r = 0.83), though not in fed butterflies of the same age range (r = -0.02). However, repeatability of CO(2) production of fed butterflies increased sharply with age, rising to 0.82 for butterflies age 8-10 d. Although food uptake mass was repeatable (r = 0.52), feeding history explained little variation in CO(2) production. We conclude that for V. cardui and possibly for other insects of similar feeding habit, variation in metabolic rate between individuals is best represented by measurements of unfed individuals of the same age or of older fed individuals.

    Sixty-two patients were randomized to receive either localized cold therapy to the cesarean section incision or routine postoperative care. Evaluation of the amount of analgesia requested, infection rate, and length of hospital stay did not show a significant difference between the two groups. There is no objective evidence to show that the use of cold therapy in postoperative cesarean section pain relief is beneficial.

    Successful vaginal birth after cesarean section is more comfortable than repeat emergency or elective cesarean section. Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P0.05). In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section. The patients' requests influenced outcome. Trial of labor should take into consideration the patient's preference, together with the proper setting.

  14. Laparoscopic Resection of Cesarean Scar Ectopic Pregnancy.

    Ades, Alex; Parghi, Sneha

    To demonstrate a technique for the laparoscopic surgical management of cesarean section scar ectopic pregnancy. Step-by-step presentation of the procedure using video (Canadian Task Force classification III). Cesarean section scar ectopic pregnancy is a rare form of ectopic pregnancy with an incidence ranging from 1:1800 to 1:2216. Over the last decade, the incidence seems to be on the rise with increasing rates of cesarean deliveries and early use of Doppler ultrasound. These pregnancies can lead to life-threatening hemorrhage, uterine rupture, and hysterectomy if not managed promptly. Local or systemic methotrexate therapy has been used successfully but can result in prolonged hospitalization, requires long-term follow-up, and in some cases treatment can fail. In the hands of a trained operator, laparoscopic resection can be performed to manage this type of pregnancy. Consent was obtained from the patient, and exemption was granted from the local Internal Review Board (The Womens' Hospital, Parkville). In this video we describe our technique for laparoscopic management of a cesarean scar ectopic pregnancy. We present the case of a 34-year-old G4P2T1 with the finding of a live 8-week pregnancy embedded in the cesarean section scar. The patient had undergone 2 previous uncomplicated cesarean sections at term. On presentation her β-human chorionic gonadotropin (β-hCG) level was 52 405 IU/L. She was initially managed with an intragestational sac injection of potassium chloride and methotrexate, followed by 4 doses of intramuscular methotrexate. Despite these conservative measures, the level of β-hCG did not adequately fall and an ultrasound showed a persistent 4-cm mass. A decision was made to proceed with surgical treatment in the form of a laparoscopic resection of the ectopic pregnancy. The surgery was uneventful, and the patient was discharged home within 24 hours of her procedure. Her serial β-hCG levels were followed until complete resolution

    Objective Aim To assess the trend in caesarean section rate, and find the causes and solutions to the high rate of ce-sarean section.Methods According to the annual reports of midwifery services from 2009 to 2013, the numbers of natural child-birth, caesarean section and others were analyzed to assess variations in caesarean sections. Forty-nine parturient women that se-lect cesarean delivery without clinical indications in the upper second-class hospital during the period of January-March 2014 are investigated by using self-designed questionnaire.Results The caesarean section rates of five years in this hospital are all higher than the national average. Its average caesarean section rate reaches to 71.40%, and the proportion of caesarean section without medical indications increases year by year. Among parturient women, the proportion of caesarean section for fear of labor pain is 89.80%, and lucky day selection cannot be ignored as a social factor for caesarean section.Conclusion To an upper second-class hospital, the hospital should improve the level of health care services in all possible conditions, and restrain the increasing of ce-sarean section rate from technical aspects. However, the reduction of cesarean section rate is not just a medical problem, but also a social problem, and it requires joint efforts of the whole society.%目的:评估剖宫产率的趋势,发现剖宫产率居高不下原因及解决措施。方法根据某院2009年1月-2013年12月助产技术年度服务报表,按照自然分娩数、剖宫产数等进行统计分析。对该院2014年1~3月入院在没有临床指征前提条件下选择剖宫产分娩的49名产妇,采用自行设计的调查问卷进行问卷调查。结果该院5年的剖宫产率均超过全国平均水平,平均值达到71.40%,且无指征剖宫产比例逐年增高。产妇中因为“害怕分娩疼痛”而选择剖宫产的占89.80%,“选好日期”这一社会因素也不容忽视。结

    The evolution of flight energetics requires that phenotypes be variable, repeatable and heritable. We studied intraspecific variation in flight energetics in order to assess the repeatability of flight metabolic rate and wingbeat frequency, as well as the functional basis of phenotypic variation in workers and drones of the bumblebee species Bombus impatiens. We showed that flight metabolic rate and wingbeat frequency were highly repeatable in workers, even when controlling for body mass variation using residual analysis. We did not detect significant repeatability in drones, but a smaller range of variation might have prevented us from finding significant values in our sample. Based on our results and previous findings, we associated the high repeatability of flight phenotypes in workers to the functional links between body mass, thorax mass, wing size, wingbeat frequency and metabolic rate. Moreover, differences between workers and drones were as predicted from these functional associations, where drones had larger wings for their size, lower wingbeat frequency and lower flight metabolic rate. We also investigated thoracic muscle metabolic phenotypes by measuring the activity of carbohydrate metabolism enzymes, and we found positive correlations between mass-independent metabolic rate and the activity of all enzymes measured, but in workers only. When comparing workers and drones that differ in flight metabolic rate, only the activity of the enzymes hexokinase and trehalase showed the predicted differences. Overall, our study indicates that there should be correlated evolution among physiological phenotypes at multiple levels of organization and morphological traits associated with flight.

METHODS: A cross-sectional study was conducted in a university hospital in Florianópolis, Southern Brazil, from 2001 to 2005. Socioeconomic, reproductive, obstetric and institutional information were collected. Data from 7,249 deliveries was obtained from medical records and admission, delivery and post-delivery records. Cox regression was used in the analysis to estimate cesarean prevalence ratios in the categories of variables studied. RESULTS: Cesarean rates increased from 27.5% to 36.5% during the period studied and they were higher than those associated with medical indications. After adjustment for confounders cesarean rates were positively associated with previous cesarean section (PR=2.65, 95% CI: 2.31;3.05, non-cephalic presentation (PR=2.23, 95%CI: 1.69;2.95, oxytocin use (PR=1.77, 95%CI: 1.43;2.19, dilatation at admission (PR=2.74, 95%CI: 2.18;3.44, and obstetrician profile (>35% of cesarean sections (PR=1.82, 95%CI: 1.36;2.42. CONCLUSIONS: The factors associated with cesarean section indicate the need of interventions focusing on women and their reproductive experience and changes in obstetrician practice as well.

    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.

    We examined whether the presence of fatigue induced by prolonged running influenced the time courses of force generating capacities throughout a series of intermittent rapid contractions. Thirteen male amateur runners performed a set of 15 intermittent isometric rapid contractions of the knee extensor muscles, (3s/5s on/off) the day before (PRE) and immediately after (POST) a half marathon. The maximal voluntary contraction force, rate of force development (RFDpeak), and their ratio (relative RFDpeak) were calculated. At POST, considering the first (out of 15) repetition, the maximal force and RFDpeak decreased (p<0.0001) at the same extent (by 22±6% and 24±22%, respectively), resulting in unchanged relative RFDpeak (p=0.6). Conversely, the decline of RFDpeak throughout the repetitions was more pronounced at POST (p=0.02), thus the decline of relative RFDpeak was more pronounced (p=0.007) at POST (-25±13%) than at PRE (-3±13%). The main finding of this study was that the fatigue induced by a half-marathon caused a more pronounced impairment of rapid compared to maximal force in the subsequent intermittent protocol. Thus, the fatigue-induced impairment in rapid muscle contractions may have a greater effect on repeated, rather than on single, attempts of maximal force production. Copyright © 2017 Elsevier B.V.

    Rates of cesarean section have risen around the world in recent years. Accordingly, much effort is being made worldwide to understand this trend and to counteract it effectively. A number of factors have been found to make it more likely that a cesarean section will be chosen, but the risks cannot yet be clearly defined. This review is based on pertinent publications that were retrieved by a selective search in the PubMed, Scopus, and DIMDI databases, as well as on media communications, analyses by the German Federal Statistical Office, and guidelines of the Association of Scientific Medical Societies in Germany (AWMF). The increased rates of cesarean section are thought to be due mainly to changed risk profiles both for expectant mothers and for their yet unborn children, as well as an increase in cesarean section by maternal request. In 1991, 15.3% of all newborn babies in Germany were delivered by cesarean section; by 2012, the corresponding figure was 31.7%, despite the fact that a medical indication was present in less than 10% of all cases. This development may perhaps be explained by an increasing tendency toward risk avoidance, by risk-adapted obstetric practice, and increasing media attention. The intraoperative and postoperative risks of cesarean section must be considered, along with complications potentially affecting subsequent pregnancies. Scientific advances, social and cultural changes, and medicolegal considerations seem to be the main reasons for the increased acceptibility of cesarean sections. Cesarean section is, however, associated with increased risks to both mother and child. It should only be performed when it is clearly advantageous.

    Cesarean delivery is frequently complicated by surgical site infections (SSIs), endometritis and urinary tract infection. Most SSIs occur after discharge from hospital, and are increasingly being used as performance indicators. Worldwide, the rate of cesarean delivery is increasing. Evidence-based guidelines recommended the use of prophylactic antibiotics prior to surgical incision. An exception is made for cesarean delivery, where narrow-range antibiotics are administered post umbilical cord...

  4. Vaginal birth after cesarean delivery: a group practice's approach to minimizing failed trial of labor.

    1998-07-01

    Objective: Among women attempting a trial of labor (TOL) after a prior abdominal delivery, 60-80% accomplish a vaginal birth after cesarean (VBAC). McMahon and coworkers (N Engl J Med, 1996) have indicated that at a 60% success level for TOL, the remaining 40% incurred enough major complications that the scheduled repeat cesarean section group was less morbid overall. The same authors speculated that a success rate of 80% might be necessary for the TOL group's morbidity to be superior. We sought to review our group's patient selection experience during an interval when successful TOL consistently exceeded 80%.Methods: The study interval ranged from January 1995 through June 1997 and was limited to patients with one previous low transverse cesarean section. Rather than using administrative or charge-related diagnoses, we analyzed a departmental database that included each delivering physician's selection of one of four VBAC categories: successful VBAC, unsuccessful VBAC, patient declined trial of labor, or physician advised against trial of labor. All deliveries were at a single institution and were performed by one of seven obstetricians in a group practice.Results: During the study interval, 332 women provided a history of a single previous cesarean delivery. Of these 332, a total of 173 attempted a TOL and 150 of the 173 (87%) were successful. Fifty-eight of the 332 (18%) declined a trial of labor despite being assessed as excellent candidates, and 101 (30%) were advised against a TOL by their physician. Most common reasons for physicians discouraging labor included malpresentation, fetal macrosomia, and clinically small pelvis. Complications for the 23 of 173 (13%) experiencing a failed TOL included 1 asymptomatic partial separation of a uterine scar and 4 cases of puerperal fever; neither transfusion nor hysterectomy was required.Conclusions: This study demonstrates that in a population of women with one prior cesarean delivery, it is possible for a group

    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

    1998-07-01

    Introduction: In 1997, medical insurance gives limited financial reimbursement to physicians who first assist cesarean sections. Therefore, a formal program was developed at our community teaching hospital using midwives in place of physicians as first assistant in cesarean section. Midwives on the midwifery service were taught the principles and procedures of obstetrical anesthesia, anatomy, and physiology of the gravid abdomen.A team approach using obstetrician/gynecologist, anesthesiologist, midwives, and operating nurses performed the tracking in a 1-day course. A 28-minute video was developed to depict the role of the midwife as first assistant. Additionally, the principles of operation room set-up and instrumentation were taught.Result: All 24 midwives on the midwifery service were involved in the teaching of first assisting an attending obstetrician. After taking the course, nurse-midwives received formal certification from the department of obstetrics and gynecology and were approved by risk management. They also received clinical privileges outlining these guidelines. Their malpractice rates have not increased. The time to complete a cesarean section has not increased for the physician, and an emergency cesarean section is no longer delayed by waiting for an assistant to arrive. Patient satisfaction has increased because of decreased waiting time for a cesarean section and increased familiarity with the entire operating team.Discussion: Midwives can be trained to first assist the obstetrician/gynecologist in a cesarean section. Since the duration of a cesarean section is not prolonged, the patient will not experience increased blood loss or infection secondary to a prolonged procedure. The patient is more relaxed since they know that their provider during labor is also one of their surgeons for the cesarean section.

    The aim of the study was to assess the clinical outcomes of surgical repair of uterine cesarean scar defects with sonography (US). Seven nonpregnant women with history of cesarean section and a large uterine scar defect were enrolled. The surgical repair was performed by minilaparotomy. The US assessment of the uterine scar was performed using a standardized approach at baseline, then at a first visit 2-3 days following the surgical intervention (V1) and at a follow-up visit 3 months later (V2). Residual myometrial thickness (RMT), width, and depth of the scar defect were measured. The mean RMT increased significantly from 1.9 mm at baseline to 8.8 mm at V1 and 8.0 mm at V2. No intraoperative complications were observed. Postmenstrual spotting and abdominal pain reported preoperatively resolved after the operation. A surgical repair procedure for an incompletely healed uterine cesarean scar is effective in increasing RMT thickness, decreasing the depth of the scar, and reducing symptoms related to the cesarean section scar defect. Further studies on post-repair pregnancy outcomes are required to evaluate whether the procedure affects the rate of cesarean scar pregnancy, morbidly adherent placenta, and/or uterine scar dehiscence and rupture. The repair of a cesarean scar defect is recommended only for symptomatic women. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:455-460, 2017. © 2017 Wiley Periodicals, Inc.

    Repeated air drying and rewetting of three soils followed by incubation at 20°C resulted in an increase in the rate of decomposition of a fraction of 14C labeled organic matter in the soils. The labeled organic matter originated from labeled glucose, cellulose and straw, respectively, metabolized...... of the treatment was least in the soil which had been incubated with the labeled material for the longest time. Additions of unlabeled, decomposable organic material also increased the rate of decomposition of the labeled organic matter. The evolution of labeled CO2 during the 1st month of incubation after...... addition was in some cases 4–10 times larger than the evolution from the controls. During the continued incubation the evolution decreased almost to the level of the controls, indicating that the effect was related to the increased biological activity in the soils during decomposition of the added material...

    Cesarean section rates are increasing worldwide, which has been paralelled by an increase in primary cesarean delivery and decrease in vaginal birth after cesarean section. Behind the different frequencies there is a number of interrelated factors including advanced maternal age, increasing incidence of obesity, assisted reproductive technologies, and maternal request for non-medical reasons. The sub-optimal management of labor and the concerns about medical liability claims and litigations increase the number of abdominal deliveries. The author reviews the changing indications for cesarean deliveries in the last few decades and summarizes the effects on the obstetrical clinical practice.

    accumulation on Findelengletscher can be reconstructed from repeated GPR measurements alone. A simple transient spatial model for firn compaction is calibrated based on a comparison with GPR data of 2013 at positions were profiles intersect. Density and water equivalent of firn layers can then be extracted along the measured GPR profiles. However, if no in-situ information from firn cores is available, the dating of reflectors as former annual summer surfaces must be verified by external information such as modelled mass balance to avoid misinterpretations. We show that helicopter-borne GPR is an effective method to derive several years of past accumulation rates of mountain glaciers. It benefits but does not depend exclusively on the time-matched availability of firn cores when overlapping profiles are mapped in subsequent years.

    Cesarean delivery is the most frequent major surgery in Finland: in 2013 over 16% of the deliveries were via cesarean route. 27% of the mothers are estimated to face complications. Optimal surgical techniques and other operation-related measures aim to reduce the incidence of complications. Recommendations favor preoperative antibiotics, vaginal preparation, transversal skin incision, non-development of bladder flap, blunt cephalo-caudad uterine extension, spontaneous placental removal, late cord clamping, continuous sutures for uterine closure and subcutaneous skin sutures. Optimal measures will not only reduce complications in cesarean deliveries but bring cost savings and unify the clinical routines and training in specialization programs.

    Full Text Available Objectives: To assess the safety and efficacy of myomectomy during cesarean section. Methods : The study design was a prospective multicentre study done in three tertiary care hospitals in Dhaka city. The subject were 30 pregnant women underwent elective or emergency myomectomy during cesarean section. All cesarean section myomectomy were performed by consultant. Intra-operative and post-operative complications such as change in haematocrit, length of operation, blood loss were estimated. Length of hospital stay was also recorded. Results : 50 Fibroid of various sizes (2-6cm were removed from 30 women. Fibroid were on the anterior uterine wall with most being subserous and intramural. Four patients had one unit of whole blood transfusion in post-operative period. No hysterectomy was done at the time of cesarean section. There was no significant frequency of blood transfusion; incidence of post- operative fever and duration of operation. The mean duration of post operative hospital study was 7.3±1.2 days. Two patients subsequently became pregnant, were also underwent repeated cesarean section in the study period. Conclusion : In selected cases myomectomy during cesarean section does not appear to result in an increased risk of intrapartum or short-term postpartum morbidity if performed by an experienced practitioner. Cesarean myomectomy is a safe surgical options with no significant complications. Keywords : Cesarean section; myomectomy; uterine myoma.

    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.

    Objective: A simplified method of cesarean delivery aimed at minimizing postoperative morbidity is illustrated.Methods: Two hundred consecutive cesarean deliveries were performed by the authors' simplified cesarean technique. Mean patient age was 27 years (range 17-46), and mean weight was 169 pounds (range 112-414). Indications for cesarean delivery included dystocia or failure to progress in labor (38%), repeat cesarean (32%), malpresentation (11.5%), fetal distress (9.5%), and other (9%).Results: Simplified cesarean delivery was successfully completed in all cases. Mean operating time was 16 minutes (range 9-33), mean blood loss was 460 mL (range 100-1150), and mean postsurgical hospitalization time was 72 hours (range 36-120). No bowel, bladder, or vascular injuries occurred. Postoperative febrile morbidity occurred in one patient (0.5%), ileus occurred in one patient (0.5%), and blood transfusion was administered to one patient (0.5%). No cases of wound infection, wound dehiscence, hematoma, or incisional hernia occurred. All patients were ambulatory on the first postoperative day. All but one patient (99.5%) tolerated a regular diet on the first postoperative day.Conclusions: The authors' technique of cesarean section appears to be a safe and efficient method for cesarean delivery associated with minimal postoperative infectious morbidity and rapid resumption of bowel and ambulatory function.

    2017-09-01

    Full Text Available The current recommendation of the World Health Organization (WHO regarding cesarean section (C-section is that this clinical practice should be carried out only under specific conditions, when the health or life of the mother/newborn dyad is threatened, and that its use should not exceed 10–15% of the total deliveries. However, over the last few decades, the frequency of C-section delivery in medium- and high-income countries has rapidly increased worldwide. This review describes the evolution of this procedure in Latin American countries, showing that today more than half of newborns in the region are delivered by C-section. Given that C-section delivery is more expensive than vaginal delivery, its use has increased more rapidly in the private than the public sector; nevertheless, the prevalence of C-section deliveries in the public sector is higher than the WHO’s recommendations and continues to increase, representing a growing challenge for Latin America. Although the medium- and long-term consequences of C-section delivery, as opposed to vaginal delivery, on the infant health are unclear, epidemiological studies suggest that it is associated with higher risk of developing asthma, food allergy, type 1 diabetes, and obesity during infancy. These findings are important, as the incidence of these diseases in the Latin American pediatric population is also increasing, particularly obesity. Although the link between these diseases and delivery mode remains controversial, recent studies indicate that the establishment of the gut microbiota is delayed in infants born by C-section during the postnatal period, i.e., during a critical developmental window for the maturation of the newborn’s immune system. This delay may favor the subsequent development of inflammatory and metabolic disorders during infancy. Accordingly, from a public health perspective, it is important to slow down and eventually reverse the pattern of increased C-section use in

    Full Text Available This cross-sectional study investigated the correlation between the CAG repeat length and the degeneration of cerebellum in spinocerebellar ataxia type 3 (SCA3 patients based on neuroimaging approaches. Forty SCA3 patients were recruited and classified into two subgroups according to their CAG repeat lengths (≥74 and <74. We measured each patient's Scale for the Assessment and Rating of Ataxia (SARA score, N-acetylaspartate (NAA/creatine (Cr ratios based on magnetic resonance spectroscopy (MRS, and 3-dimensional fractal dimension (3D-FD values derived from magnetic resonance imaging (MRI results. Furthermore, the 3D-FD values were used to construct structural covariance networks based on graph theoretical analysis. The results revealed that SCA3 patients with a longer CAG repeat length demonstrated earlier disease onset. However, the CAG repeat length did not significantly correlate with their SARA scores, cerebellar NAA/Cr ratios or cerebellar 3D-FD values. Network dissociation between cerebellar regions and parietal-occipital regions was found in SCA3 patients with CAG ≥ 74, but not in those with CAG < 74. In conclusion, the CAG repeat length is uncorrelated with the change of SARA score, cerebellar function and cerebellar structure in SCA3. Nevertheless, a longer CAG repeat length may indicate early structural covariance network dissociation.

Here, we report a 27-year-old woman para 1 live 1 with chief complaint of headache, confusion, nausea, and vomiting 2 days after cesarean section. She was anxious and had palpitation. On physical examination, fever, tachycardia, tachypnea, high blood pressure, and right thyroid nodule were found. She was managed as pregnancy-induced hypertension at first. In laboratory data, epinephrine, norepinephrine, metanephrine, normetanephrine, and vanillylmandelic acid were increased in 24 h urine collection. An adrenal mass was detected in abdominal computed tomography. Regarding clinical and paraclinical findings, pheochromocytoma was diagnosed. The patient received medical treatment, but it was not effective; hence, she underwent adrenalectomy. PMID:27076898

    To study the feasibility and safety of trial of labor after cesarean section (TOLAC). Retrospective analysis of five medical center of Guangdong province from January 2011 to December 2015 hospitalized delivery information, compare the same scar TOLAC (research group) with the scar pregnancy (control group) pregnancy outcomes, to study the feasibility and safety of TOLAC. (1) During 2011-2015, total delivery 95 600 cases in five medical center, 13 824 cases of thme with uterine scar pregnancy, including 12 027 cases elective repeat cesarean section and 1 797 cases (13.00%, 1 797/13 824) with scar uterus vaginal trial of labor. Among 1 308 cases of vaginal delivery, the success for trial of labor rate was 72.79% (1 308/1 797). From 2011 to 2015, there were increased rate of pregnancy after cesarean section, which were respectively 10.71%, 13.28%, 14.45%, 15.54% and 16.98%. The will of vaginal birth were rising and the rate were respectively 11.85%, 12.25%, 13.49%, 13.82% and 12.93%. (2) There were 489 (27.21%, 489/1 797) cases of scar uterus maternal emergency cesarean section in the trial of labor, reason for "social factors" require for cesarean delivery have 68 cases, the percentage was 13.91% (68/489), compared with control group (7.18%, 206/2 869), the difference was statistically significant difference (χ(2)=27.356, P=0.000). Doctors diagnosed as "aura uterine rupture" in the labor was 11.86% (58/489), compared with that in control group (1.43%, 41/2 869), the differences were statistically significant difference (χ(2)=1 578.223, P=0.000). (3) The incidence of uterine rupture of the research group (0.74%, 9/1 211) was significantly higher than that of control group (0.01%,2/31 200; χ(2)> 2 000, P=0.000). The incidence of postpartum hemorrhage in research group was 6.94% (84/1 211), compared with that in the control group (3.05%, 951/31 200), there was statistically significant difference (χ(2)=16.328, P=0.000).

    Caesarean section is the most common surgery performed in all hospitals of second level of care in the health sector and more frequently in private hospitals in Mexico. To determine the behavior that caesarean section in different hospitals in the health sector in the city of Aguascalientes and analyze the indications during the same period. A descriptive and cross in the top four secondary hospitals in the health sector of the state of Aguascalientes, which together account for 81% of obstetric care in the state, from 1 September to 31 October 2008. Were analyzed: indication of cesarean section and their classification, previous pregnancies, marital status, gestational age, weight and minute Apgar newborn and given birth control during the event. were recorded during the study period, 2.964 pregnancies after 29 weeks, of whom 1.195 were resolved by Caesarean section with an overall rate of 40.3%. We found 45 different indications, which undoubtedly reflect the great diversity of views on the institutional medical staff to schedule a cesarean section. Although each institution has different resources and a population with different characteristics, treatment protocols should be developed by staff of each hospital to have the test as a cornerstone of labor, also request a second opinion before a caesarean section, all try to reduce the frequency of cesarean section.

    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

    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.

    Recently, a growing tendency for cesarean birth has been noted both, in Poland and worldwide. Non-obstetric problems constitute a large part of indications for cesarean section. Many ophthalmologists and obstetricians still believe that high myopia, the presence of peripheral retinal degenerations, history of retinal detachment surgery, diabetic retinopathy, or glaucoma are indications for surgical termination of pregnancy. However, these recommendations are not evidence-based. The literature offers no proof that high myopia and previous retinal surgery increase the risk of retinal detachment during spontaneous vaginal delivery. There is only one indication for cesarean section in myopic patients, i.e. the presence of choroidal neovascularization, which can cause subretinal bleeding with acute visual loss. Prolonged and intensified Valsalva maneuver during labor in patients with an active proliferative diabetic retinopathy may be an indication for an elective cesarean section. Uterine contractions during the second stage of vaginal delivery lead to a marked elevation of intraocular pressure. Intraocular pressure fluctuations during the delivery may damage retinal ganglion cells, resulting in further progression of visual field. Thus, glaucoma associated with advanced visual field changes is the next ophthalmic indication for cesarean section. The report presents the current state of knowledge concerning the effect of pregnancy on pre-existing ocular disorders and the influence of physiological changes on the clinical course of these diseases during the stages of natural delivery. The authors discuss also the ophthalmic indications for cesarean section.

    ratio, 1.23; 95% confidence interval, 0.60-2.49). Rates of other wound complications were also not significantly different. Risks of surgical site infection were similar with Vicryl and Monocryl closure in all subgroups assessed. The relative risks were not materially affected by whether diabetes or obesity was present, cesarean was scheduled or unscheduled, primary or repeat cesarean, or the subcutaneous layer was closed. Post hoc power analysis indicated that we had 80% power to detect >2-fold difference in surgical site infections. Subcuticular skin closure with 4-0 Vicryl is associated with comparable rates of surgical site infection and other wound complications as 4-0 Monocryl. While this is an observational study with the potential for selection bias and residual confounding, our results suggest physician preference is acceptable for choice of subcuticular suture material at cesarean.

    In recent decades, the global rates of cesarean delivery have rapidly increased. Nonetheless, the influence of cesarean deliveries on surgical complications later in life has been understudied. To investigate whether previous cesarean delivery increases the risk of reoperation, perioperative and postoperative complications, and blood transfusion when undergoing a hysterectomy later in life. This registry-based cohort study used data from Danish nationwide registers on all women who gave birth for the first time between January 1, 1993, and December 31, 2012, and underwent a benign, nongravid hysterectomy between January 1, 1996, and December 31, 2012. The dates of this analysis were February 1 to June 30, 2016. Cesarean delivery. Reoperation, perioperative and postoperative complications, and blood transfusion within 30 days of a hysterectomy. Of the 7685 women (mean [SD] age, 40.0 [5.3] years) who met the inclusion criteria, 5267 (68.5%) had no previous cesarean delivery, 1694 (22.0%) had 1 cesarean delivery, and 724 (9.4%) had 2 or more cesarean deliveries. Among the 7685 included women, 3714 (48.3%) had an abdominal hysterectomy, 2513 (32.7%) had a vaginal hysterectomy, and 1458 (19.0%) had a laparoscopic hysterectomy. In total, 388 women (5.0%) had a reoperation within 30 days after a hysterectomy. Compared with women having vaginal deliveries, fully adjusted multivariable analysis showed that the adjusted odds ratio of reoperation for women having 1 previous cesarean delivery was 1.31 (95% CI, 1.03-1.68), and the adjusted odds ratio was 1.35 (95% CI, 0.96-1.91) for women having 2 or more cesarean deliveries. Perioperative and postoperative complications were reported in 934 women (12.2%) and were more frequent in women with previous cesarean deliveries, with adjusted odds ratios of 1.16 (95% CI, 0.98-1.37) for 1 cesarean delivery and 1.30 (95% CI, 1.02-1.65) for 2 or more cesarean deliveries. Blood transfusion was administered to 195 women (2.5%). Women having

    Consumers show high interindividual variability in food liking during repeated exposure. To investigate consumer liking during repeated exposure, data is often interpreted on a product level by averaging results over all consumers. However, a single product may elicit inconsistent behaviors in consumers; averaging will mix and hide possible subgroups of consumer behaviors, leading to a misinterpretation of the results. To deal with the variability in consumer liking, we propose to use clustering on data from consumer-product combinations to investigate the nature of the behavioral differences within the complete dataset. The resulting behavioral clusters can then be used to describe product acceptance. To test this approach we used two independent data sets in which young adults were repeatedly exposed to drinks and snacks, respectively. We found that five typical consumer behaviors existed in both datasets. These behaviors differed both in the average level of liking as well as its temporal dynamics. By investigating the distribution of a single product across typical consumer behaviors, we provide more precise insight in how consumers divide in subgroups based on their product liking (i.e. product modality). This work shows that taking into account and using interindividual differences can unveil information about product acceptance that would otherwise be ignored.

    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

    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

    High-resolution repeat multibeam echosounder measurements on the Lower Missouri River near Boonville, Missouri, USA show bedform movement and sand storage patterns over daily to seasonal time scales and a range of discharges. Higher flows are frequently, but not always, associated with larger bedforms, higher bedform movement rates, and higher bedload transport rates. Measurements of the temporal and spatial variability in sand dune sizes, transport rates, and sand storage across the river channel have increased understanding of the dynamics of habitats utilized by benthic organisms over multiple life stages and daily to seasonal time scales.

    Full Text Available Objective: Cesarean rates in recent decades have been increasing and a number of studies have shown that cesarean increases maternal morbidities. The aim of this study is to compare the quality of life after cesarean and vaginal delivery.Methods: This prospective study was carried out on 356 pregnant women visiting urban health centers in Shahroud City, Northeast Iran, in 2011. The subjects completed the quality of life questionnaire in the third trimester of pregnancy and at 8 weeks postpartum.Results: In primiparas, the mean global QOL scores for the cesarean and vaginal delivery groups were 67.65 ± 12.7 and 72.12 ± 11.8, respectively. Also, the scores for the physical, psychological and social domains of QOL as well as the global score of QOL were higher in the vaginal delivery group than the cesarean group (p<0.05. In the case of primiparas, multiple regression analysis revealed that after adjusting for education, desirability of pregnancy and the General Health Questionnaire score, the delivery type remained as a predictor of the scores for the physical (R2=1.7%; B=-3.826; p=0.031; CI [-7.301, -.350] and social (R2=2.5%; B=-5.708; p=0.017; CI [-10.392, -1.023] domains of QOL and the global QOL score (R2=2.6%; B=-4.065; p=0.006; CI [-6.964, -1.164]. While multiparas, there was no relationship between QOL and type of delivery.Conclusion: In this sample of low-risk women, cesarean negatively affected the QOL of primiparas. More studies with larger sample sizes should be conducted to examine the effects of cesarean on QOL in both primiparas and multiparas within a shorter period after delivery.

    Congenital nasolacrimal duct obstruction (dacryostenosis) with a persisting membrane at Hasner's valve is the most common cause of persistent tear and ocular discharge in infants. To evaluate whether there is an association between congenital dacryostenosis and delivery via cesarean section. In a prospective study we examined 107 children (mean age 9.2 ± 7.1 months) with congenital dacryostenosis. We evaluated data about the mode of delivery (vaginal delivery versus cesarean section) and gestational age at the time of birth. Within the first 8 months of life children were treated by probing using local anesthesia, whereas older children were treated using general anesthesia. After the age of 11 months treatment included nasolacrimal duct intubation with a bicanalicular stent. Statistical analyses were performed using binomial tests, Fisher's exact test and the t-test. In this study 51 children delivered by cesarean section were compared with 56 children delivered by spontaneous vaginal delivery. A total of 44 age-matched pairs from both groups were evaluated in order to eliminate confounding factors due to gestational age at delivery. Based on the published rate of cesarean sections from the same region of the State of Hesse between 2002-2004 we observed a statistically significant association between congenital dacryostenosis and delivery by cesarean section among the 88 age-matched patients (P = 0.009). Moreover, subgroup analysis revealed a significant association between congenital dacryostenosis and delivery by primary cesarean section (P = 0.00004). The prevalence of surgical treatment was not statistically different between both groups based on the mode of delivery (P = 0.8). Our results suggest that delivery via cesarean section is associated with a significantly higher prevalence of congenital dacryostenosis.

    Elevated resting heart rate is associated with increased cardiovascular risk, particularly in patients with left ventricular systolic dysfunction. Heart rate is not monitored routinely in these patients. We hypothesized that routine monitoring of heart rate would increase its prognostic value in patients with left ventricular systolic dysfunction. We analyzed the relationship between heart rate measurements and a range of adverse cardiovascular outcomes, including hospitalization for worsening heart failure, in the pooled placebo-treated patients from the morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with coronary disease and left ventricULar dysfunction (BEAUTIFUL) trial and Systolic Heart failure treatment with the If inhibitor ivabradine (SHIFT) Trial, using standard and time-varying covariate Cox proportional hazards models. By adjusting for other prognostic factors, models were fitted for baseline heart rate alone or for time-updated heart rate (latest heart rate) alone or corrected for baseline heart rate or for immediate previous time-updated heart rate. Baseline heart rate was strongly associated with all outcomes apart from hospitalization for myocardial infarction. Time-updated heart rate increased the strengths of associations for all outcomes. Adjustment for baseline heart rate or immediate previous time-updated heart rate modestly reduced the prognostic importance of time-updated heart rate. For hospitalization for worsening heart failure, each 5 beats/min increase in baseline heart rate and time-updated heart rate was associated with a 15% (95% confidence interval, 12-18) and 22% (confidence interval, 19-40) increase in risk, respectively. Even after correction, the prognostic value of time-updated heart rate remained greater. In patients with left ventricular systolic dysfunction, time-updated heart rate is more strongly related with adverse cardiovascular outcomes than baseline heart rate. Heart rate should be measured to

    2016-11-01

    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.

    Full Text Available Background: Repeated failure of in vitro fertilization treatment is frustrating to the patients and their clinicians. Various treatment plans and a change of protocol have been suggested for “low responders”; however, patients who fail treatment repeatedly inspite of good quality embryos pose a special therapeutic challenge. Additional challenge would be imposed on that particular group when the local IVF regulating low does not permit surplus embryo freezing. Objective: To examine whether sequential transfer of embryos on day 3 and on day 5 after ovum pick-up improves IVF/ET success rates in patients with repeated consecutive IVF failures (⩾ 3 trials compared to day 3 alone, with the background that local regulation prohibits embryo freezing. Study design: Randomized controlled study. Women scheduled for IVF/ET with repeated consecutive IVF failures (⩾ 3 trials were randomized to either sequential transfer of embryos on day 3 and on day 5 after ovum pick-up (Group I = 74 or conventional day 3 transfer (Group II = 73 as a control. The primary outcome measures were clinical pregnancy rate and implantation rate. The secondary outcome measures were ongoing pregnancy rate and early pregnancy loss. Results: Baseline and cycle characteristics were comparable in both groups. Clinical pregnancy rate (per embryo transfer was significantly higher in sequential ET group (37. 8% compared to that in day 3 group (21.9% (P value <0.05. Also, implantation rate (per embryos transferred was significantly higher in sequential ET group (17.1% compared to that in control group (10.5% (P value <0.01. Similarly, ongoing pregnancy (per embryo transfer was significantly higher in sequential ET group (33. 8% compared to that in day 3 group (19.2% (P value <0.05. Conclusions: Patients with repeated implantation failures, treatment with the sequential embryo transfer approach had significantly improved pregnancy outcomes compared to regular day 3 transfers

    Cesarean section by maternal request is the one performed on a pregnant woman without medical indication and without contraindication to vaginal delivery. There is great controversy over requested cesarean section. Potential risks include complications in subsequent pregnancies, such as uterine rupture, placenta previa and accreta. Potential benefits of requested cesareans include a lower risk of postpartum hemorrhage in the first cesarean and fewer surgical complications compared with vaginal delivery. Cesarean section by request should never be performed before 39 weeks. RESUMO A cesariana a pedido materno é aquela realizada em uma gestante sem indicações médicas e sem contraindicação para tentativa do parto vaginal. Existe grande controvérsia sobre a realização da cesariana a pedido. Riscos potenciais da cesariana a pedido incluem complicações em gravidezes subsequentes, tais como: rotura uterina, placenta prévia e acretismo. Potenciais benefícios da cesariana a pedido englobam um menor risco de hemorragia pós-parto na primeira cesariana e menos complicações cirúrgicas quando comparada ao parto vaginal. A cesariana a pedido jamais deve ser realizada antes de 39 semanas.

    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.

    Full Text Available The prevalence of obesity has reached pandemic proportions across nations. Morbid obesity has a dramatic impact on pregnancy outcome. Cesarean section in these women poses many surgical, anesthetic, and logistical challenges. In view of the increased risk of cesarean delivery in morbidly obese women, the practical implications and complications are reviewed in this article. A Medline search was conducted to review the recent relevant articles in english literature on cesarean section in morbidly obese women. The types of incisions and techniques used during cesarean delivery, intra-operative and postpartum complications, anesthetic and logistical issues, maternal morbidity and mortality were reviewed. Morbidly obese women with a body mass index (BMI >40 kg/m 2 are at increased risk of pregnancy complications and a significantly increased rate of cesarean delivery. Low transverse skin incisions and transverse uterine incisions are definitely superior and must be the first option. Closure of the subcutaneous layer is recommended, but the placement of subcutaneous drains remains controversial. Thromboprophylaxis adjusted to body weight and prophylactic antibiotics help in reducing postpartum morbidity. Morbidly obese women are at increased risk of postpartum infectious morbidity. Weight reduction in the postpartum period and thereafter must be strongly encouraged for optimal future pregnancy outcomes and well-being.

    To estimate the effect of prior successful vaginal birth after cesarean (VBAC) on the rate of uterine rupture and delivery outcome in women undergoing labor after cesarean. A retrospective cohort study of all women attempting labor after cesarean delivery in a university-affiliated tertiary-hospital (2007-2014) was conducted. Study group included women attempting vaginal delivery with a history of cesarean delivery and at least one prior VBAC. Control group included women attempting first vaginal delivery following cesarean delivery. Primary outcome was defined as the rate of uterine rupture. Secondary outcomes were delivery and maternal outcomes. Of 62,463 deliveries during the study period, 3256 met inclusion criteria. One thousand two hundred and eleven women had VBAC prior to the index labor and 2045 underwent their first labor after cesarean. Women in the study group had a significantly lower rate of uterine rupture 9 (0.7%) in respect to control 33 (1.6%), p = .036, and had a higher rate of successful vaginal birth (96 vs. 84.9%, p cesarean, prior VBAC appears to be associated with lower rate of uterine rupture and higher rate of successful vaginal birth.

    Decrease in body temperature is common during general and regional anesthesia. Forced-air warming intraoperative during cesarean section under spinal anesthesia seems not able to prevent it. The hypothesis considers that active warming before the intraoperative period avoids temperature loss during cesarean. Forty healthy pregnant patients undergoing elective cesarean section with spinal anesthesia received active warming from a thermal gown in the preoperative care unit 30min before spinal anesthesia and during surgery (Go, n=20), or no active warming at any time (Ct, n=20). After induction of spinal anesthesia, the thermal gown was replaced over the chest and upper limbs and maintained throughout study. Room temperature, hemoglobin saturation, heart rate, arterial pressure, and tympanic body temperature were registered 30min before (baseline) spinal anesthesia, right after it (time zero) and every 15min thereafter. There was no difference for temperature at baseline, but they were significant throughout the study (p<0.0001; repeated measure ANCOVA). Tympanic temperature baseline was 36.6±0.3°C, measured 36.5±0.3°C at time zero and reached 36.1±0.2°C for gown group, while control group had baseline temperature of 36.4±0.4°C, measured 36.3±0.3°C at time zero and reached 35.4±0.4°C (F=32.53; 95% CI 0.45-0.86; p<0.001). Hemodynamics did not differ throughout the study for both groups of patients. Active warming 30min before spinal anesthesia and during surgery prevented a fall in body temperature in full-term pregnant women during elective cesarean delivery.

    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

    To analyze if clinically insignificant prostate cancer (ClPC) is more frequently detected with repeat prostate biopsies,we retrospectively analyzed the records of 2146 men diagnosed with prostate cancer after one or more prostate biopsies.The patients were divided into five groups according to the number of prostate biopsies obtained,e.g.group 1 had one biopsy,group 2 had two biopsies and group 3 had three biopsies.Of the 2146 patients diagnosed with prostate cancer,1956 (91.1%),142 (6.6%),38 (1.8%),9 (0.4%) and 1 (0.1%) men were in groups 1,2,3,4 and 5,respectively.Groups 4 and 5 were excluded because of the small sample sizes.The remaining three groups (groups 1,2 and 3) were statistically analyzed.There were no differences in age or prostate-specific antigen level among the three groups.ClPC was detected in 201 (10.3%),28 (19.7%) and 9 (23.7%) patients in groups 1,2 and 3,respectively (P<0.001).A multivariate analysis showed that the number of biopsies was an independent predictor to detect CIPC (0R=2.688 for group 2; 0R=4.723 for group 3).In conclusion,patients undergoing multiple prostate biopsies are more likely to be diagnosed with CIPC than those who only undergo one biopsy.However,the risk still exists that the patient could have clinically significant prostate cancer.Therefore,when counseling patients with regard to serial repeat biopsies,the possibility of prostate cancer overdiagnosis and overtreatment must be balanced with the continued risk of clinically significant disease.

  12. Rare complications of cesarean scar

    Full Text Available Cesarean scar pregnancy (CSP and cesarean scar dehiscence (CSD are the most dreaded complications of cesarean scar (CS. As the incidence of CS is increasing worldwide, so is the incidence of CSP, especially in cases with assisted reproduction techniques. It is of utmost importance to diagnose CSP in the early first trimester, as it can lead to myometrial rupture with fatal outcome. On the other hand, CSD may be encountered during pregnancy or in the postpartum period. CSD in the postpartum period is very rare and can cause secondary postpartum hemorrhage (PPH leading to increased maternal morbidity or even death if not diagnosed and managed promptly. Both complications can be diagnosed on ultrasonography (USG and confirmed on magnetic resonance imaging (MRI. These two conditions carry high morbidity and mortality. In this article, we highlight the role of imaging in the early diagnosis and management of these conditions.

    2011-01-01

    This paper addresses the automatic classification of X-rated videos by analyzing its obscene sounds. In this paper, obscene sounds refer to audio signals generated from sexual moans and screams during sexual scenes. By analyzing various sound samples, we determined the distinguishable characteristics of obscene sounds and propose a repeated curve-like spectrum feature that represents the characteristics of such sounds. We constructed 6,269 audio clips to evaluate the proposed feature, and separately constructed 1,200 X-rated and general videos for classification. The proposed feature has an F1-score, precision, and recall rate of 96.6%, 98.2%, and 95.2%, respectively, for the original dataset, and 92.6%, 97.6%, and 88.0% for a noisy dataset of 5dB SNR. And, in classifying videos, the feature has more than a 90% F1-score, 97% precision, and an 84% recall rate. From the measured performance, X-rated videos can be classified with only the audio features and the repeated curve-like spectrum feature is suitable to...

    2011-11-01

    Cesarean section rate is steadily increasing and in Israel it has risen to 20%. MultipLe and different reasons have led to this phenomenon, among them are non-indicated cesarean sections. Although health care providers disagree whether this development is medically, ethically and publically justified, national associations allow it, while respecting those obstetricians who decline to do so. In Israel there are some hospitals which allow non-indicated cesarean sections, whereas others reject them. When discussing this issue with the patients, documentation is advised concerning the reasons for approval or rejection of the patients' request in order to avoid future complaints in the case of adverse outcome. Low risk vaginal delivery should be regarded as a natural process and not as a medical treatment and keeping balanced and reasonable decisions may help to contain the phenomenon and avoid a situation in which the "Golem" created by the medical system, counteracts.

  15. Force response of the fingertip pulp to repeated compression--effects of loading rate, loading angle and anthropometry.

    Repeated loading of the fingertips has been postulated to contribute to tendon and nerve disorders at the wrist during activities associated with prolonged fingertip loading such as typing. To fully understand the pathomechanics of these soft tissue disorders, the role of the fingertip pulp in attenuating the applied dynamic forces must be known. An experiment was conducted to characterize the response of the in vivo fingertip pulp under repeated, dynamic, compressive loadings, to identify factors that influence pulp dynamics, and to better understand the force modulation by the pulp. Twenty subjects tapped repeatedly on a flat plate with their left index finger, while the contact force and pulp displacement were measured simultaneously. Tapping trials were conducted at three fingertip contact angles from the horizontal plane (0 degree, 45 degrees, and 90 degrees) and five tapping rates (0.25, 0.5, 1, 2, and 3 Hz). The fingertip pulp responds as a viscoelastic material, exhibiting rate-dependence, hysteresis, and a nonlinear force-displacement relationship. The pulp was relatively compliant at forces less than 1 N, but stiffened rapidly with displacement at higher forces for all loading conditions. This suggests that high-frequency forces of a small magnitude (< 1 N) are attenuated by the nonlinearly stiffening pulp while these forces of larger magnitude are transmitted to the bone. Pulp response was significantly influenced by the angle of loading. Fingertip dimensions, gender, and subject age had little to no influence on pulp parameters.

    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

    2016-08-01

    Full Text Available Background: P Cesarean delivery rates have been increasing throughout the world. Parallel to the developments in the world the cesarean rate in Turkey has risen to 48.1% in 2013. Some of the social factors were related with cesarean births. The purpose of this study was to determine cesarean birth rates and to find out social factors affecting the cesarean birth in primiparous women.Methods: This study was conducted in Burdur Province, Turkey between the dates of 1 Jan 2012–31 Dec 2012 on 223 primiparous women. The data was collected with data collection form prepared by the researchers by using face-to-face interview technique. In these analyses, chi-square and Backward Logistic regression analyses were used.Results: In multivariate analyses, the place of delivery (OR: 11.2 [2.9-42.46] in private hospital and OR: 6.1 [2.6-14.1] in university hospital; time of the birth (OR: 7.1 [3.1-16.0]; doctor’s effect (OR: 4.0 [1.8-8.95] and husband’s employment status (OR: 2.23 [1.0-4.7] have been identified as factors affecting the caesarean delivery in primiparous women.Conclusion: Although the results do not show all of the factors affecting the caesarean delivery in primiparous women, they reveal that medical reasons are not the only reason in this increase trend. Health policy makers and health professionals are required to identify the causes of this increase and to take measures.Keywords: Cesarean sections, Primiparity, Social determinants, Epidemiology

    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.

    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.

    While measurements of ice-sheet surface elevation change are increasingly used to assess mass change, the processes that control the elevation fluctuations not related to ice-flow dynamics (e.g. firn compaction and accumulation) remain difficult to measure. Here we use radar data from the Thwaites Glacier (West Antarctica) catchment to measure the rate of thickness change between horizons of constant age over different time intervals: 2009-10, 2010-11 and 2009-11. The average compaction rate to approximately 25m depth is 0.33ma(exp -1), with largest compaction rates near the surface. Our measurements indicate that the accumulation rate controls much of the spatio-temporal variations in the compaction rate while the role of temperature is unclear due to a lack of measurements. Based on a semi-empirical, steady-state densification model, we find that surveying older firn horizons minimizes the potential bias resulting from the variable depth of the constant age horizon. Our results suggest that the spatiotemporal variations in the firn compaction rate are an important consideration when converting surface elevation change to ice mass change. Compaction rates varied by up to 0.12ma(exp -1) over distances less than 6km and were on average greater than 20% larger during the 2010-11 interval than during 2009-10.

    The increase in frequency of cesareans that has been noted through 70's, not diminished--like it was expected--perinatal morbidity and mortality. The most important indications to cesarean are distocias, previous cesarean and fetal stress. In 1998 frequency of cesarean deliveries in our hospital was 35% of the pregnancy attended. The claim of this study was to determine risks factors to cesarean in our hospital. A case-control study was performed, selecting 165 cases (cesareans) and 328 controls (via vaginal). It was determined OR of the risks factors and atribuible fraction. Data were analyzed by X2. The most important indications to cesarean delivery were: distocias (39%, n = 64); previous cesarean (23%, n = 41) and fetal stress (11%, n = 21). There was not significative differences in age, height and rupture membrane time in both groups. History of cesarean delivery gave major risk to another surgical intervention (OR = 12.7, p = < 0.0001, atribuible fraction 92%). Nuliparous (OR = 6.6, p < 0.00000, atribuible fraction 85%), second gestation (OR = 1.8, p = 0.002) or history of abortion (OR = 1.8, p = 0.04) were factors mainly associated to cesarean delivery. We concluded that the precise 'medications of this surgical intervention specially in nuliparous or previous cesarean delivery cases must be replanteated to diminish its elevated frequency.

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...

  4. Vacuum-assisted cesarean section

    Full Text Available Ross W McQuivey,1 Jon E Block2 1Clinical Innovations, Salt Lake City, UT, 2Independent consultant, San Francisco, CA, USA Abstract: There has been a dramatic rise in the frequency of cesarean sections, surpassing 30% of all deliveries in the US. This upsurge, coupled with a decreasing willingness to allow vaginal birth after cesarean section, has resulted in an expansion of the use of vacuum assistance to safely extract the fetal head. By avoiding the use of a delivering hand or forceps blade, the volume being delivered through the uterine incision can be decreased when the vacuum is used properly. Reducing uterine extensions with their associated complications (eg, excessive blood loss in difficult cases is also a theoretical advantage of vacuum delivery. Maternal discomfort related to excessive fundal pressure may also be lessened. To minimize the risk of neonatal morbidity, proper cup placement over the “flexion point” remains essential to maintain vacuum integrity and reduce the chance of inadvertent detachment and uterine extensions. Based on the published literature and pragmatic clinical experience, utilization of the vacuum device is a safe and effective technique to assist delivery during cesarean section.

    To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005-2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 women who had undergone repeat cesarean section were identified and their operation reports were reviewed. Descriptions of complete uterine rupture or uterine dehiscence in operation reports were compared with diagnoses registered in EPRS with International Classification of Diseases codes version 10 (ICD-10). Sensitivity and specificity of complete uterine rupture registration were calculated. There were 13 women with a registered diagnosis of uterine rupture. After reviewing medical records of women with repeat cesarean section, seven additional cases of complete uterine rupture, 33 cases of uterine dehiscence and 39 cases of extremely thin myometrium were identified. The incidence of complete uterine rupture and uterine dehiscence for women who delivered by repeat cesarean section was 2.8% and 10.1%, respectively. Diagnosis of complete uterine rupture was underreported in the EPRS by 35% and diagnosis of uterine dehiscence was missing in 100% of cases.

    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. 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. 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. 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 of providers and facilities and detect

    To examine the association between gestational weight gain (GWG) and cesarean delivery including cesarean delivery on maternal request (CDMR) among low-risk women. A total of 1,009,987 Chinese nulliparous women who delivered live term singletons during 1993-2010 were included. GWG, according to maternal pre-pregnancy body mass index-specified z-scores, was categorized into five groups: less than -1.2, -1.2 to less than -0.6, -0.6 to 0.6 (reference), more than 0.6 to 1.2, and more than 1.2. Multivariate log-binomial regression models were used to estimate the adjusted risk ratios and 95% confidence intervals (95% CIs). GWG was positively associated with overall cesarean and CDMR after adjusting for various confounders. Adjusted risk ratios for cesarean were 0.75 (95% CI, 0.73-0.77), 0.84 (95% CI, 0.82-0.85), 1.00, 1.16 (95% CI, 1.14-1.19), and 1.32 (95% CI, 1.29-1.35) in five ascending GWG categories, and 0.70 (95% CI, 0.67-0.73), 0.80 (95% CI, 0.78-0.82), 1.00, 1.20 (95% CI, 1.18-1.23), and 1.43 (95% CI, 1.40-1.45) for CDMR. The graded positive associations were consistent across levels of maternal pre-pregnancy body mass index, and in strata defined by southern and/or northern provinces, urban and/or rural residence, maternal age at delivery, year of delivery, and level of delivering hospital. Even among low-risk women, higher GWG was monotonically associated with an increased risk of cesarean delivery, indicating that limiting GWG could benefit to curb the rate of both medically necessary and unnecessary cesareans.

    Herein we report on 1 more case of vesicouterine fistula following cesarean section with review and update of the literature concerning this unusual topic. The disease presented with vaginal urinary leakage, cyclic hematuria and amenorrhea. The fistula was successfully repaired by delayed surgery. Actually, all over the world the prevalence of the disease is increasing for the frequent use of the cesarean section. Fistulas may develop immediately after a cesarean section, manifest in the late puerperium or occur after repeated procedures. Spontaneous healing is reported in 5% of cases. Vesicouterine fistulas present with vaginal urinary leakage, cyclic hematuira (menouria), amenorrhea, infertility, and first trimester abortions. The diagnosis is ruled out by showing the fistulous track between bladder and uterus as well as by excluding other more frequent urogenital fistulas. The disease treatment options include conservative treatment as well as surgical repair. Rarely, patients refuse any kind of treatment because of the benignity of symptoms and prognosis of the disease. Conservative management by bladder catheterization for at least 4-8 weeks is indicated when the fistula is discoveredjust after delivery since there is good chance for spontaneous closure of the fistulous track. Hormonal management should be tried in women presenting with Youssef's syndrome. Surgery is the maninstay and definitive treatment of vesicouterine fistulas after cesarean section. Patients scheduled for surgery should undergo pretreatment of urinary tract infections. Surgical repair of vesico-uterine fistulas are performed by different approaches which include the vaginal, transvesical-retroperitoneal and transperitoneal access which is considered the most effective with the lowest relapse rate. Recently, laparoscopy has been proposed as a valid option for repairing vesicouterine fistulas. The endoscopic treatment may be effective in treating small vesicouterine fistulas. The pregnancy

    The cornerstone of concerns over trial of labor after cesarean (TOLAC) is the risk of uterine rupture. The purpose of this study was to document the rate of uterine rupture during TOLAC and to delineate its severity and consequences. We retrospectively collected the data on vaginal and cesarean deliveries after a previous cesarean section with specific emphasis on uterine rupture and dehiscence in our center from 2006 through 2013. 22,670 deliveries were registered, with 18.2% rate of cesarean section. 2890 women had a single cesarean scar; of them 1206 delivered vaginally and 194 were re-operated during unsuccessful TOLAC. Seven cases of uterine rupture and 16 cases of dehiscence were recorded. There were no maternal, intrapartum or neonatal deaths, and no cesarean hysterectomy. There was one re-laparotomy, one ICU admission, and one blood transfusion; one neonate was admitted to NICU. TOLAC was successful in 86.1% of cases. Cautious selection and close monitoring of candidates are the cornerstones of successful management of TOLAC. Readily available facilities for emergency cesarean delivery and concerted obstetrical team can save the mother and child from catastrophic complications.

    Eighty-nine participants performed a set of recognition judgment and confidence rating tasks twice. Half of the new items presented in the second task had already presented as old items to the participants in the first task. Analysis of the second task responses, showed a positive correlation between confidence and performance for the old items, and a negative correlation for the new items. In particular, a strong negative correlation was observed when items presented in the first task were presented as "new" in the second task. This negative correlation reflects "source monitoring error" where the participants falsely recognized the items in the first task as those presented in the second, because they were unaware of making source misattributions.

  13. NMR Analysis of Amide Hydrogen Exchange Rates in a Pentapeptide-Repeat Protein from A. thaliana.

    At2g44920 from Arabidopsis thaliana is a pentapeptide-repeat protein (PRP) composed of 25 repeats capped by N- and C-terminal α-helices. PRP structures are dominated by four-sided right-handed β-helices typically consisting of mixtures of type II and type IV β-turns. PRPs adopt repeated five-residue (Rfr) folds with an Rfr consensus sequence (STAV)(D/N)(L/F)(S/T/R)(X). Unlike other PRPs, At2g44920 consists exclusively of type II β-turns. At2g44920 is predicted to be located in the thylakoid lumen although its biochemical function remains unknown. Given its unusual structure, we investigated the biophysical properties of At2g44920 as a representative of the β-helix family to determine if it had exceptional global stability, backbone dynamics, or amide hydrogen exchange rates. Circular dichroism measurements yielded a melting point of 62.8°C, indicating unexceptional global thermal stability. Nuclear spin relaxation measurements indicated that the Rfr-fold core was rigid with order parameters ranging from 0.7 to 0.9. At2g44920 exhibited a striking range of amide hydrogen exchange rates spanning 10 orders of magnitude, with lifetimes ranging from minutes to several months. A weak correlation was found among hydrogen exchange rates, hydrogen bonding energies, and amino acid solvent-accessible areas. Analysis of contributions from fast (approximately picosecond to nanosecond) backbone dynamics to amide hydrogen exchange rates revealed that the average order parameter of amides undergoing fast exchange was significantly smaller compared to those undergoing slow exchange. Importantly, the activation energies for amide hydrogen exchange were found to be generally higher for the slowest exchanging amides in the central Rfr coil and decreased toward the terminal coils. This could be explained by assuming that the concerted motions of two preceding or following coils required for hydrogen bond disruption and amide hydrogen exchange have a higher activation energy

    A six year follow-up evaluation of our original cesarean section reduction program is presented. While establishing obstetric practice guidelines was accomplished, two prerequisites remain critical: lowering cesarean utilization was to be accomplished without harm to mother or fetus, and a target rate was prospectively determined. The results after 6 years indicate that total cesarean rates of 10-12% can consistently be achieved without adverse outcome. Additionally, operative vaginal procedures were employed less that 3% of cases. Separate analysis of 580 breech deliveries failed to show an effect of route of delivery on mortality. This effort indicates that long-term reductions and cesarean utilization are possible with a comprehensive departmental program designed to accomplish achieving a target rate of 11%.

    2012-08-01

    Cesarean delivery is the most common surgical procedure performed in the United States, yet the techniques used during this procedure often vary significantly among providers. The purpose of this review was to evaluate and outline current evidence behind the cesarean delivery technique. A search of the PubMed database was conducted using the terms cesarean section and cesarean delivery and the technique of interest, for example, cesarean section prophylactic antibiotics. Few aspects of the cesarean delivery were found to have high-quality consistent evidence to support use of a particular technique. Because many aspects of the procedure are based on limited or no data, more studies on specific cesarean delivery techniques are clearly needed. Providers should be aware of which components of the cesarean delivery are evidence-based versus not when performing this procedure.

  16. Do monkey F5 mirror neurons show changes in firing rate during repeated observation of natural actions?

    Mirror neurons were first discovered in area F5 of macaque monkeys. In humans, noninvasive studies have demonstrated an increased blood oxygen level-dependent (BOLD) signal in homologous motor areas during action observation. One approach to demonstrating that this indicates the existence of mirror neurons in humans has been to employ functional (f)MRI adaptation to test whether the same population of neurons is active during both observation and execution conditions. Although a number of human studies have reported fMRI adaptation in these areas, a recent study has shown that macaque mirror neurons do not attenuate their firing rate with two repetitions. Here we investigated whether mirror neurons modulate their firing rate when monkeys observed the same repeated natural action multiple times. We recorded from 67 mirror neurons in area F5 of two macaque monkeys while they observed an experimenter perform a reach-to-grasp action on a small food reward using a precision grip. Although no changes were detectable for the first two repetitions, we show that both the firing rate and the latency at which mirror neurons discharged during observation were subtly modulated by the repetition of the observed action over 7-10 trials. Significant adaption was mostly found in the period immediately before the grasp was performed. We also found that the local field potential activity in F5 (beta-frequency range, 16-23 Hz), which is attenuated during action observation, also showed systematic changes with repeated observation. These LFP changes occurred well in advance of the mirror neuron adaptation. We conclude that macaque mirror neurons can show intra-modal adaptation, but whether this is related to fMRI adaptation of the BOLD signal requires further investigation.

    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

    High rates of cesarean birth are a significant health care quality issue, and birth centers have shown potential to reduce rates of cesarean birth. Measuring this potential is complicated by lack of randomized trials and limited observational comparisons. Cesarean rates vary by provider type, setting, and clinical and nonclinical characteristics of women, but our understanding of these dynamics is incomplete. We sought to isolate labor setting from other risk factors in order to assess the effect of birth centers on the odds of cesarean birth. We generated low-risk cohorts admitted in labor to hospitals (n = 2527) and birth centers (n = 8776) using secondary data obtained from the American Association of Birth Centers (AABC). All women received prenatal care in the birth center and midwifery care in labor, but some chose hospital admission for labor. Analysis was intent to treat according to site of admission in spontaneous labor. We used propensity score adjustment and multivariable logistic regression to control for cohort differences and measured effect sizes associated with setting. There was a 37% (adjusted odds ratio [OR], 0.63; 95% confidence interval [CI], 0.50-0.79) to 38% (adjusted OR, 0.62; 95% CI, 0.49-0.79) decreased odds of cesarean in the birth center cohort and a remarkably low overall cesarean rate of less than 5% in both cohorts. These findings suggest that low rates of cesarean in birth centers are not attributable to labor setting alone. The entire birth center care model, including prenatal preparation and relationship-based midwifery care, should be studied, promoted, and implemented by policy makers interested in achieving appropriate cesarean rates in the United States. © 2016 by the American College of Nurse-Midwives.

    To describe our technique for the repair of a cesarean section uterine scar defect after removal of an ectopic pregnancy from the scar in a patient desiring future pregnancies. Step-by-step explanation of the procedure using video (Canadian Task Force classification III). Uterine scar dehiscence/defect is a known complications of multiple cesarean deliveries that can result in abnormal bleeding, infertility, and cesarean scar ectopic pregnancy. With the increasing number of cesarean sections performed in the United States, the prevalence of this complication is rising. Nonetheless, there currently are no standardized surgical treatment guidelines available to manage this pathology through a minimally invasive approach. In this video, we describe our technique for the surgical management of a symptomatic cesarean section scar defect. We performed a robotic-assisted laparoscopic repair of this defect in a 40-year-old G4P3013 with a recent cesarean section scar ectopic pregnancy managed by endometrial curettage, with subsequent persistent abnormal vaginal bleeding. A repeat ultrasound revealed a low uterine segment defect consistent with dehiscence. She was referred to us because she desired a conservative treatment given her desire for future pregnancies. The defect was localized by hysteroscopy and laparoscopy after developing the bladder flap. The scar tissue around the defect was resected, and the freshened edges of the defect were closed using delayed absorbable suture. Chromopertubation confirmed the watertightness of the repair. Postoperatively, the patient had regular normal periods, and her hysterosalpingogram didn't show any uterine defect. Robotic-assisted laparoscopic repair of cesarean section scar defect is a feasible and safe procedure when done with respect to anatomy and following sound surgical technique. With the increasing number of cesarean sections, gynecologists will be dealing with this pathology more frequently, and need to become more

    Background: P Cesarean delivery rates have been increasing throughout the world. Parallel to the developments in the world the cesarean rate in Turkey has risen to 48.1% in 2013. Some of the social factors were related with cesarean births. The purpose of this study was to determine cesarean birth rates and to find out social factors affecting the cesarean birth in primiparous women. Methods: This study was conducted in Burdur Province, Turkey between the dates of 1 Jan 2012–31 Dec 2012 on 223 primiparous women. The data was collected with data collection form prepared by the researchers by using face-to-face interview technique. In these analyses, chi-square and Backward Logistic regression analyses were used. Results: In multivariate analyses, the place of delivery (OR: 11.2 [2.9–42.46] in private hospital and OR: 6.1 [2.6–14.1] in university hospital); time of the birth (OR: 7.1 [3.1–16.0]); doctor’s effect (OR: 4.0 [1.8–8.95]) and husband’s employment status (OR: 2.23 [1.0–4.7]) have been identified as factors affecting the caesarean delivery in primiparous women. Conclusion: Although the results do not show all of the factors affecting the caesarean delivery in primiparous women, they reveal that medical reasons are not the only reason in this increase trend. Health policy makers and health professionals are required to identify the causes of this increase and to take measures. PMID:27648420

    Objective: To explore and analyze the indications and causes of cesarean section on Pemba island of Zanzibar in Africa to improve the quality of obstetrics. Methods: 564 patients performed cesarean section in Abdulla Mzee Hospital of Pemba from January, 2008 to December, 2011 were selected, and statistics was conducted by the method of retrospective analysis. Results: The rate of cesarean section in Abdulla Mzee Hospital of Pemba was 10.01%. The primary causes of cesarean section included cephalopelvic disproportion (27.13%), scar uterus (23.40%), preeclampsia and eclampsia (13.30%), fetal distress in uterus (9.40%), fetal factors (9.75%) and complication of pregnancy (6.91%). Conclusion: Cesarean section plays a great role in the treatment of dystocia, some complications of pregnancy and reducing the mortality of pregnant women and perinatal infants, but in the area with relatively undeveloped medical conditions in Africa, cesarean section still takes great risks. Unnecessary cesarean section cannot reduce the incidence of postpartum hemorrhage and neonatal morbidity. The local medical staff should improve the midwifery technique, establish and perfect the formal antenatal examination system to improve the quality of maternity.

    The aims of this study were to analyze the predictive factors for the use of intrauterine balloon insertion and to evaluate the efficacy and factors affecting failure of uterine tamponade with a Bakri balloon during cesarean section for abnormal placentation. We reviewed the medical records of 137 patients who underwent elective cesarean section for placenta previa between July 2009 and March 2014. Cesarean section and Bakri balloon insertion were performed by a single qualified surgeon. The Bakri balloon was applied when blood loss during cesarean delivery exceeded 1,000 mL. Sixty-four patients (46.7%) required uterine balloon tamponade during cesarean section due to postpartum bleeding from the lower uterine segment, of whom 50 (78.1%) had placenta previa totalis. The overall success rate was 75% (48/64) for placenta previa patients. Previous cesarean section history, anterior placenta, peripartum platelet count, and disseminated intravascular coagulopathy all significantly differed according to balloon success or failure (all pcesarean section for placenta previa to preserve the uterus. This method is simple to apply, non-invasive, and inexpensive. However, possible factors related to failure of Bakri balloon tamponade for placenta previa patients such as prior cesarean section history, anterior placentation, thrombocytopenia, presence of DIC at the time of catheter insertion, and catheter drainage volume more than 500 mL within 1 hour of catheter placement should be recognized, and the next-line management should be prepared in advance.

    The purpose of this study was to evaluate elective cesarean delivery for women with a history of anal sphincter rupture. The effectiveness of cesarean delivery in parous women with a previous anal sphincter rupture was determined by decision analysis. The outcomes were excess cesarean deliveries and morbidity and mortality rates per prevented case of anal incontinence. We needed 2.3 cesarean deliveries to prevent one case of anal incontinence. A woman who chooses a cesarean delivery has a 11.3% risk of morbidity compared with a 4.2% risk for vaginal delivery (relative risk, 2.7; 95% CI, 2.6-2.8; P<.001). The relative risk for maternal death from a cesarean delivery is 2.6 (95% CI, 1.5-4.5; P<.001). Continent women with a previous anal sphincter rupture who are delivered vaginally are at high risk for permanent anal incontinence. Cesarean delivery will prevent most cases of anal incontinence, although marginally increasing maternal risk. The increased risk may be justified by the potential benefits. Patients should be counseled on these risks and benefits.

    Cesarean section rates are rising in the United States and were at an all time high of 29 percent in 2004. Within this context, the issue of cesarean section on maternal request has been described as being part of a "perfect storm" of medical, legal and personal choice issues, and the lack of an opposing view. An increasing cesarean section rate adds an economic burden on already highly stressed medical systems. There is an incremental cost of cesarean section compared to vaginal delivery. The issue of cost must also be considered more broadly. Rising cesarean section rates are associated with a longer length of stay and a higher occupancy rate. This high occupancy rate leads to the diversion of critical care obstetric transports and has dramatically reduced patient satisfaction. These diversions, and the resultant inability to provide needed care to pregnant women, represent a profound societal cost. These critical care diversions and reduced patient satisfaction also negatively impact a health care institution's financial bottom line and competitiveness. The impact of a rising cesarean section rate on both short and long-term maternal and neonatal complications, and their associated costs, must also be taken into account. The incidence of placenta accreta is increasing in conjunction with the rising cesarean section rate. The added costs associated with this complication (MRI, Interventional Radiology, transfusion, hysterectomy, and intensive care admission) can be prohibitive. It has also been demonstrated that infants born by scheduled cesarean delivery are more likely to require advanced nursery support (with all its associated expense) than infants born to mothers attempting vaginal delivery. The practice of maternal request cesarean section, with limited good data and obvious inherent risk and expense, is increasing in the USA. Patient autonomy and a woman's right to choose her mode of delivery should be respected. However, in our opinion, based on the

    Conclusion: Previous cesarean scar pregnancy if not detected early can be associated with high morbidity and mortality. Therefore, the possibility of this pregnancy should be considered in pregnant women with uterine bleeding, abdominal pain as well as a history of cesarean section. It should be noted that after previous cesarean scar pregnancy was definitely diagnosed via ultrasound examination, treatment necessitates to be started utilizing methotrexate to ensure the future fertility of the mother.

    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.

    Cesarean birth has been associated with higher risk of obesity in offspring, but previous studies have focused primarily on childhood obesity and have been hampered by limited control for confounders. To investigate the association between cesarean birth and risk of obesity in offspring. A prospective cohort study was conducted from September 1, 1996, to December 31, 2012, among participants of the Growing Up Today Study, including 22 068 offspring born to 15 271 women, followed up via questionnaire from ages 9 to 14 through ages 20 to 28 years. Data analysis was conducted from October 10, 2015, to June 14, 2016. Birth by cesarean delivery. Risk of obesity based on International Obesity Task Force or World Health Organization body mass index cutoffs, depending on age. Secondary outcomes included risks of obesity associated with changes in mode of delivery and differences in risk between siblings whose modes of birth were discordant. Of the 22 068 offspring (20 950 white; 9359 male and 12 709 female), 4921 individuals (22.3%) were born by cesarean delivery. The cumulative risk of obesity through the end of follow-up was 13% among all participants. The adjusted risk ratio for obesity among offspring delivered via cesarean birth vs those delivered via vaginal birth was 1.15 (95% CI, 1.06-1.26; P = .002). This association was stronger among women without known indications for cesarean delivery (adjusted risk ratio, 1.30; 95% CI, 1.09-1.54; P = .004). Offspring delivered via vaginal birth among women who had undergone a previous cesarean delivery had a 31% (95% CI, 17%-47%) lower risk of obesity compared with those born to women with repeated cesarean deliveries. In within-family analysis, individuals born by cesarean delivery had 64% (8%-148%) higher odds of obesity than did their siblings born via vaginal delivery. Cesarean birth was associated with offspring obesity after accounting for major confounding factors. Although additional research is

    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

Retrospective study, carried out over a period of 1 year in a university hospital having a level 3 perinatal activity, including the 499 primary cesarean sections of 2013. Two groups were defined by parity: nulliparous patients (group 1) and multiparous patients who had never previously been delivered by cesarean section (group 2). We have assessed the indication of every primary cesarean section and health status of newborns in each group. Groups 1 and 2 respectively included 369 and 130 patients. The cesarean section rate in 2013 was 24.7% with a primary cesarean section rate of 17%. Seventy-four percent of the primary caesarean deliveries were performed on nulliparous women and 26% on multiparous (Pcesarean delivery were non-reassuring fetal heart rate tracing (47.1%), failure to progress (24.8%) for which nulliparous women were more involved (29% vs. 13%, Pcesarean section rate.

    Objectives. We studied if both observed and unobserved maternal health in African American women in hospitals or communities were associated with cesarean delivery of infants. Methods. We examined the relationship between African American race and cesarean delivery among 493 433 women discharged from 255 Californian hospitals in 2010 using administrative data; we adjusted for patient comorbidities and maternal, fetal, and placental risk factors, as well as clustering of patients within hospitals. Results. Cesarean rates were significantly higher overall for African American women than other women (unadjusted rate 36.8% vs 32.7%), as were both elective and emergency primary cesarean rates. Elevated risks persisted after risk adjustment (odds ratio generally > 1.27), but the prevalence of particular risk factors varied. Although African American women were clustered in some hospitals, the proportion of African Americans among all women delivering in a hospital was not related to its overall cesarean rate. Conclusions. To address the higher likelihood of elective cesarean delivery, attention needs to be given to currently unmeasured patient-level health factors, to the quality of provider–physician interactions, as well as to patient preferences.

    Fear of true rupture remains the main indication for repeat section. Between 1972 and 1987 there were 2434 patients with one or more prior section and 1350 (55%) were permitted trial of labor, the remainder, having had two or more previous sections (maximum number, 10), had repeat surgery. Induction was employed in 31% and oxytocin for induction or acceleration in 32% patients. The first period (1972-1982) had 844 and the second period (1982-1987) had 506 trial of labor patients. Improved management resulted in the true rupture rate falling from 0.6% (1:169) to 0.2% (1:506) and the elimination of procedure-related perinatal death. There were two maternal deaths with repeat section and none with trial of labor. We have achieved a plateau for cesarean section (10-11%) and a continuing fall in the uncorrected hospital perinatal mortality, which has averaged 10.6/1000 for the years 1982-1986 inclusive.

    China has one of the highest rates of cesarean sections in the world. However, limited epidemiological studies have evaluated the risk factors for cesarean section among Chinese women. Thus, the aim of this cohort study was to investigate the associations between pre-pregnancy BMI, gestational weight gain (GWG) and the risk of cesarean section in China. A total of 57,891 women with singleton, live-born, term pregnancies were included in this analysis. We found that women who were overweight or obese before pregnancy had an elevated risk of cesarean section. Women with a total GWG above the Institute of Medicine (IOM) recommendations had an adjusted OR for cesarean section of 1.45 (95% CI, 1.40-1.51) compared with women who had GWG within the IOM recommendations. Women with excessive BMI gain during pregnancy also had an increased risk of cesarean section. When stratified by maternal pre-pregnancy BMI, there was a significant association between excessive GWG and increased odds of cesarean section across all pre-pregnancy BMI categories. These results suggest that weight control efforts before and during pregnancy may help to reduce the rate of cesarean sections.

    In Morocco cesarean section rate has increased from 2% in 1992 to 16% in 2011. This was associated with increased per- and postoperative mortality and morbidity, which was 19% in our case series. This study is the first of its kind to be conducted in the eastern region of Morocco and aims to analyze the comprehensive epidemiologic profile of maternal complications related to cesarean section on the basis of 2417 cases observed in the Maternity Department at the El Farabi Hospital, Oujda. We conducted an observational, descriptive, retrospective study of a series of 2416 patients undergoing cesarean section in the Maternity Department at the El Farabi Hospital, Oujda, over the period 1 January 2011-31 December 2013. Out of 24464 deliveries, 2416 were cesarean sections, reflecting a rate of 9.87%. The frequency of complications related to cesarean section was 19.45%. Postoperative complications accounted for 63.6% of the complications dominated by infection. Haemorrhagic complications accounted for 25.53% of all complications. 4 cases of maternal deaths were recorded. If the increased rate of cesarean sections has contributed to improve maternal-fetal prognosis, the surgical act itself is not complication-free, which leads us to review its indications for improved patient management.

    To compare cesarean section (CS) using open or closed visceral peritoneum of the bladder flap (BF) in relation to fluid collection in vesico-uterine space (VUS) by ultrasound (US) and clinical outcome. A prospective cohort of repeat CS in 474 in advanced first and second stage of labor was studied. All women underwent a Misgav Ladach CS, in local combined anesthesia. These were divided into two groups by surgical management of the BF at the time of CS: Group I (n = 262), with visceral peritoneum left open and Group II (n = 212), with visceral peritoneum closed. An US check for the fluid collections in the VUS was done in the third post-operative day. The two groups were also clinically compared for: intra-operative estimated blood loss, the need for post-CS pain killers, febrile morbidity and duration of hospital stay. Visceral peritoneum (VP) closure resulted in a significant increase blood collections in the VUS (p post-operative fever, need for post-operative analgesia, require antibiotic administration and prolonged hospitalisation (p < 0.05). VP suturing of women requiring CS for dystocia is associated to increased rate of blood collection in the VUS, which could possibly explain the higher rate of puerperal complications in these patients. These data clearly indicate that suturing the VP of the BF in women undergoing CS for dystocia is contraindicated. This data could be probably extrapolated to all cesarean deliveries.

    The aim of this paper was to investigate the acute effects of two different initial heart rates intensities when testing the repeated sprint ability (RSA) performances in young soccer players. Since there are many kinds of pre-match warm-ups, we chose to take as an absolute indicator of internal load the heart rate reached at the end of two different warm-up protocols (60 vs. 90% HRmax) and to compare the respective RSA performances. The RSA tests were performed on fifteen male soccer players (age: 17.9±1.5 years) with two sets of ten shuttle-sprints (15+15 m) with a 1:3 exercise to rest ratio, in different days (randomized order) with different HR% (60 & 90% HRmax). In order to compare the different sprint performances a Fatigue Index (FI%) was computed, while the blood lactate concentrations (BLa-) were measured before and after testing, to compare metabolic demand. Significant differences among trials within each sets (P4 mmol/L(-1)).

    The purpose of this investigation was to assess the influence of sodium bicarbonate supplementation on maximal force production, rate of force development (RFD), and muscle recruitment during repeated bouts of high-intensity cycling. Ten male and female (n = 10) subjects completed two fixed-cadence, high-intensity cycling trials. Each trial consisted of a series of 30-s efforts at 120% peak power output (maximum graded test) that were interspersed with 30-s recovery periods until task failure. Prior to each trial, subjects consumed 0.3 g/kg sodium bicarbonate (ALK) or placebo (PLA). Maximal voluntary contractions were performed immediately after each 30-s effort. Maximal force (F max) was calculated as the greatest force recorded over a 25-ms period throughout the entire contraction duration while maximal RFD (RFD max) was calculated as the greatest 10-ms average slope throughout that same contraction. F max declined similarly in both the ALK and PLA conditions, with baseline values (ALK: 1,226 ± 393 N; PLA: 1,222 ± 369 N) declining nearly 295 ± 54 N [95% confidence interval (CI) = 84-508 N; P force vs. maximum rate of force development during a whole body fatiguing task.

    The Leguminosae has emerged as a model for studying angiosperm plastome evolution because of its striking diversity of structural rearrangements and sequence variation. However, most of what is known about legume plastomes comes from few genera representing a subset of lineages in subfamily Papilionoideae. We investigate plastome evolution in subfamily Mimosoideae based on two newly sequenced plastomes (Inga and Leucaena) and two recently published plastomes (Acacia and Prosopis), and discuss the results in the context of other legume and rosid plastid genomes. Mimosoid plastomes have a typical angiosperm gene content and general organization as well as a generally slow rate of protein coding gene evolution, but they are the largest known among legumes. The increased length results from tandem repeat expansions and an unusual 13 kb IR-SSC boundary shift in Acacia and Inga. Mimosoid plastomes harbor additional interesting features, including loss of clpP intron1 in Inga, accelerated rates of evolution in clpP for Acacia and Inga, and dN/dS ratios consistent with neutral and positive selection for several genes. These new plastomes and results provide important resources for legume comparative genomics, plant breeding, and plastid genetic engineering, while shedding further light on the complexity of plastome evolution in legumes and angiosperms.

    Our objective was to determine the incidence and mortality rates associated with emergency peripartum hysterectomy, factors that lead to uncontrolled hemorrhage and emergency peripartum hysterectomy, and to determine the relationship between cesarean section and risk of emergency peripartum hysterectomy. Studies published between January 1, 2000 and December 31, 2012 were identified using PubMed, OVID and Web of Science databases. Studies were included if they reported incidence rates for emergency peripartum hysterectomy, factors that lead to hemorrhage and emergency peripartum hysterectomy, or the association of emergency peripartum hysterectomy with cesarean section in high-income countries. Four hundred and fifty-one studies were identified, and 52 were included. The incidence of emergency peripartum hysterectomy ranged from 0.20 to 5.09 per 1000 deliveries with a median incidence rate of 0.61 per 1000 deliveries. These rates have increased over time. Rates varied by region/country, specifically with the United States reporting higher rates than North American, Asian, Oceania, and European countries. The most common factor leading to emergency peripartum hysterectomy was placental abnormalities. Both cesarean section and prior cesarean section were strong risk factors for emergency peripartum hysterectomy with higher risks conferred for each additional cesarean section. The mean percentage of maternal deaths for EPH survivors was 3.0 %. Given the association of cesarean section with emergency peripartum hysterectomy, the increased risk of emergency peripartum hysterectomy should be factored into the decision of whether to proceed with cesarean delivery, particularly for women who desire more children.

    Full Text Available Introduction: Decision for cesarean section may lead to the stress for women in delivery. Stress response requires longer recovery time in post cesarean section patients. Most of patients who experience stress before and after surgical is associated with wound healing delay. When this condition continues, the wound will have a higher risk of infection. The objective of this study was to analyze correlation between stress and wound healing phase in post cesarean section patients. Method: A cross sectional design was used in this study. The population were women with cesarean section, both elective or emergency, in Delivery Room I RSU Dr. Soetomo Surabaya. Samples were recruited by using purposive sampling, with 28 samples who met to the inclusion criterias. The observed variables were stress and wound healing phase in post cesarean section patient. Stress data were collected by interview and wound healing measurement done by observation on the 3rd day post cesarean section. Result: The result showed that women with stress experience wound healing delay. The characteristic of wound healing delay was prolonged on inflammation phase, nevertheless there was presence of granulation tissue. Spearman’s rho correlation showed that correlation value r=0.675 with p=0.000. Discussion: It can be concluded that there was strong significant correlation between stress and wound healing phase in post cesarean section patients. It is important to give this information to the patients with cesarean section in order to prevent stress and delay in wound healing phase.

    The cesarean section (C) frequency has increased dramatically as high as 62%. This situation has been producing a real preoccupation in all the world as well as in México. Documented bibliography about this subject, is unquestionable. We feel that at this time there is a lack of punctuals strategies in order to reduce the high frequency of C. Our communication analyzes this problem in relation to antecedents, evolution and integrated general strategies in order to reduce the C rates. Special analysis and comments involve amnioinfusion, trials for vaginal deliveries in case of previous cesarean section, prostaglandins, and external version. With these actions, at the Antiguo Hospital Civil de Guadalajara we have achieved 10.8% of C. rates, without any increase in fetomaternal morbility and/or mortality.

    The current U.S. cesarean section rate (32.2%) is recognized as too high in light of its negative health impacts on women and infants. Efforts are underway in several states and individual hospitals to lower the rate of cesarean section among low-risk women, defined as nulliparous (first birth), term (≥37 weeks gestation), singleton (one baby), vertex (head down presentation; NTSV). We conducted a case study of one hospital's experience with NTSV cesarean sections to see whether race and insurance status affect the probability of cesarean indication. Many cesarean indications are ambiguous, and biases may seep into decisions with ambiguous diagnoses. We conducted a retrospective chart review of women who had NTSV cesarean sections at a tertiary care hospital in an urban New England city between June 2013 and November 2013. We analyzed the data using multinomial logistic regression to examine the marginal effect of race and health insurance status on the predicted probability for NTSV cesarean indication. We find that Black and Hispanic women have a lower predicted probability of having a cesarean section for cephalopelvic disproportion than do White women and that women with private health insurance have a lower predicted probability of having a cesarean section for nonreassuring fetal heart rate and for a clinical indication than do women without private health insurance. We suggest biases may seep into clinicians' decisions to perform an NTSV cesarean section. Hospital quality improvement efforts are aided by an examination of sociodemographic factors that influence clinician decision making in the specific hospital being studied.

    The epidemiologic link between cesarean birth and childhood obesity is unresolved, partly because most studies come from industrialized settings where many post-birth factors affect the risk for obesity. We take advantage of an unusual ethnographic situation where hospital and cesarean birth modes have recently been introduced among Yucatec Maya subsistence farmers, but young children have had minimal exposure to the nutritional transition. While we expect to find very low rates of childhood obesity, we predict that cesarean-born children will be larger and heavier than vaginally born children. Weight and height were collected monthly on 108 children aged 0-5 (3576 observations total). Birth mode and birthweight were collected by maternal interview. Data were analyzed using linear mixed models that compare child growth [Maya population-specific Z-scores for weight-for-age and body mass index-for-age (WAZ and BMIZ)] in cesarean and vaginally born children aged 0-5 years. The cesarean rate was 20%, no children were obese, and 5% were overweight. Cesarean birth was a significant predictor of child WAZ and BMIZ after accounting for maternal effects, child birthweight, and sex. Children who were born by cesarean to mothers with high BMI had the highest WAZ of all children by 5 years of age, and the highest BMIZ of all children at all ages. Cesarean-born Maya children had higher BMI than vaginally born children, even in the absence of many known confounding factors that contribute to childhood obesity. Child growth was most sensitive to birth mode when mothers had high BMI. © 2016 Wiley Periodicals, Inc.

    Full Text Available This paper evaluates the association of maternal variables and of variables related to prenatal and delivery care with cesarean sections at a public and at a private maternity. A retrospective cross-sectional study was performed at a public maternity clinic (2,889 deliveries and at a private maternity clinic (2,911 deliveries in the city of Ribeirão Preto, São Paulo State, Brazil. The prevalence of cesarean sections was 18.9% at the public maternity clinic and 84.3% at the private one. The factors associated with cesarean sections at both hospitals were: mothers from other cities, aged > 25 years and with hypertension. Having more than one child was a protective factor. At the public hospital, cesarean sections were more frequent on Wednesdays and from 12:00 to 23:59 hours of any day of the week, whereas at the private hospital they occurred on any day, though were less common on Sundays, and at any time except in the early morning. At the private hospital, cesarean sections were more frequent when performed by the doctor who had provided the prenatal care. Non-medical factors were more associated with cesarean sections in the private maternity clinic than biological or clinical factors related to pregnancy.Este artigo avalia a associação de variáveis maternas e aquelas relacionadas ao cuidado pré-natal e ao parto com a ocorrência de cesáreas em um hospital público e em um hospital privado.

    Every year 1.5 million cesarean section procedures are performed worldwide. As many women decide to get pregnant again, the population of pregnant women with a history of cesarean section is growing rapidly. For these women prediction of cesarean section scar performance is still a serious clinical problem. Starting in 2005, the study included 308 nonpregnant women with a history of low transverse cesarean section. The following ultrasonographic parameters of the cesarean section scar in the nonpregnant uterus were assessed: the residual myometrial thickness (RMT) and the width (W) and the depth (D) of the triangular hypoechoic scar niche. During 8 years of follow-up, 41 of these women were referred to our department for delivery. In all cases, a repeat cesarean section was performed and the lower uterine segment was assessed. Two independent statistical methods namely the logit model and Decision Tree analysis were used to determine the relation between the appearance of the cesarean section scar in the nonpregnat state and the performance of the scar in the next pregnancy. The logit model revealed that the D/RMT ratio showed significant correlation with cesarean section scar dehiscence (P-value of 0.007). Specifically, a D/RMT ratio value greater than 1.3035 indicated that the likelihood of dehiscence was greater than 50%. The Decision Tree analysis revealed that a diagnosis of dehiscence versus non-dehiscence could be based solely on one criterion, a D/RMT ratio of at least 0.785. The sensitivity of this method was 71%, and the specificity was 94%. Assessment of the cesarean section scar in the nonpregant uterus can be used to predict the occurrence of scar dehiscence in the next pregnancy.

    Objective 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). Design 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. Methods 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. Results 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. Conclusion 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. PMID:25574961

    Estimates of a trait heritability and repeatability can get at an idea of its usefulness for being an individual characteristic and its ability to change under selection pressure. Heritability and repeatability of energetic parameters still poorly studied in birds. The most important physiological characteristic of homoiotherms is resting metabolic rate (RMR), which, in the absence of productive processes, does not exceed basal metabolic rate (BMR). We estimated BMR repeatability in free-living pied flycatchers in Moscow Region (55 degrees 44' N, 36 degrees 51' E; 1992-2008) and Tomsk (56 degrees 20' N, 84 degrees 56' E; 2008-2009) populations over intervals from 40 days to 3 years. In Moscow Region population, BMR repeatability amounted to tau = 0.34 +/- 0.10 (n=80) if measured over 1 year interval, tau = 0.60 +/- 0.15 (n=19) if measured over 2 years interval, and tau = 0.85 +/- 0.13 (n=6) if measured over 3 years interval providing that consecutive BMR measurements were done in the same period of reproductive season. In Tomsk population, BMR repeatability, measured over 1 year interval, amounted to tau = 0.49 +/- 0.11 (n=50). Repeatability is a measure of a trait constancy and sets the upper limit of its heritability. To estimate RMR heritability, cross-fostering experiments have been conducted in 2003-2005 with flycatchers of Moscow Region population. RMR of chicks positively correlated with BMR of their biological fathers, whereas such correlation in metabolic rates between chicks and their foster fathers was absent. The RMR heritability estimate turned out to be h2 = 0.43 +/- 0.17 (n=210). The obtained estimates of heritability and repeatability of fundamental energetic traits are rather high for physiological features. This suggests the existence of a potential for direct selection on BMR and evolutionary stable diversity of avian populations with regard to basal metabolic rate.

    Abstract Unfortunately, the prevalence of cesarean section has increased in recent years. Whereas awareness of the prevalence and causes is inevitable for planning and effective interventions, so aim of this study has designed and conducted for reviewing of systematic Prevalence and caesarean causes in Iran. In this meta-analysis, the required information have been collected using several keywords which are Cesarean section rate, Cesarean section prevalence, delivery, childhood, childbirth, relative causes, relative frequency, Iran and their Persian equivalents have been collected from databases such as CINAHL, Science Direct, PubMed, Magiran, SID, Iranmedex. Finally, we found 706 related articles and selected 34 articles among them for studying of cesarean Prevalence. We used CMA software with random model for Meta-Analysis. The prevalence of Cesarean was estimated48%. Using content analysis, Factors influencing the incidence of cesarean section were divided to 3 categories including social and demographic factors, obstetric-medical causes and non-obstetric-medical causes. Maternal education and grand multiparity in the field of demographic and social factors, previous cesarean in the field of obstetric-medical causes and fear of normal-vaginal delivery (NVD) and doctor’s suggestion in the field of non-obstetric-medical causes were major causes of Cesarean. According to the high prevalence of caesarean section and it upward development, it seems to be essential designing and implementing of programs and interventions effectiveness including providing of Possibility of painless childbirth and education and psychological interventions, increasing of quality of natural delivery services, proper culture and prohibiting of doctors from Personal opinions and profit.

    We describe maternal childbirth goals among women planning either cesarean or vaginal birth. Women in the third trimester planning cesarean or vaginal birth were asked to report up to five childbirth goals. Goal achievement was assessed postpartum. Based on free-text responses, discrete goal categories were identified. Goals and goal achievement were compared between the two groups. Satisfaction was rated on a visual analogue scale and was compared with goal achievement. The sample included 163 women planning vaginal birth and 69 women planning cesarean. Twelve goal categories were identified. Only women planning vaginal birth reported a desire to achieve fulfillment related to childbirth. Women planning cesarean were less likely to express a desire to maintain control over their own responses during childbirth and more likely to report a desire to avoid complications. The 72 women who achieved all stated goals reported significantly higher mean satisfaction scores than the 94 women reporting that at least one goal was not achieved (P  =  0.001). Goal achievement was higher among women planning cesarean than among those planning vaginal birth (52.2% versus 23.1%, P  <  0.001). This research furthers our understanding of women's attitudes regarding cesarean childbirth and definitions of a successful birth experience. © Thieme Medical Publishers.

    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.

    To investigate the overall incidence and risk factors for persistent pain and its interference with daily life after cesarean section. Prospective long-term follow-up study. Karolinska University Hospital, Stockholm, Sweden. 260 healthy women who underwent elective cesarean section. Information on demographics, medical history, postoperative pain and analgesic requirements was collected. A questionnaire consisting of the Brief Pain Inventory was posted at 3, 6 and 12 months after surgery. Women rated pain intensity as well as interference with factors related to general function and quality of life. The overall incidence and risk factors for persistent postoperative pain at three time points. Persistent pain was considered a secondary outcome. At 3, 6 and 12 months respectively 40, 27 and 22% of patients reported pain in one or more locations, in the surgical site as well as in other areas. A psychological indication, as well as a first cesarean section, increased the risk for pain at 3 months. Severe postoperative pain in the immediate postoperative period or undergoing a first cesarean section were significant independent risk factors for the development of persistent pain up to 6 months after cesarean section. Parameters related to quality of life were significantly impaired in women with persistent pain. Several factors, including severe postoperative pain, were shown to influence the risk for persistent pain after cesarean section. Long-term pain markedly affected women's wellbeing. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Objective To describe labor patterns in women with a trial of labor after cesarean (TOLAC) with normal neonatal outcomes. Study Design In a retrospective observational study at 12 U.S. centers (2002–2008), we examined time interval for each centimeter of cervical dilation and compared labor progression stratified by spontaneous or induced labor in 2,892 multiparous women with TOLAC (second delivery) and 56,301 nulliparous women at 37 0/7 to 41 6/7 weeks of gestation. Analyses were performed including women with intrapartum cesarean delivery, and then repeated limiting only to women who delivered vaginally. Results Labor was induced in 23.4% of TOLAC and 44.1% of nulliparous women (Plabor (Plabor (P=.099); however, TOLAC had lower maximum doses of oxytocin compared to nulliparous women: median (90th percentile): 6 (18) mU/min versus 12 (28) mU/min, respectively (Plabor duration for TOLAC versus nulliparous women with spontaneous labor from 4–10cm was 0.9 (2.2) hours longer (P=.007). For women who entered labor spontaneously and achieved vaginal delivery, labor patterns for TOLAC were similar to nulliparous women. For induced labor, labor duration for TOLAC versus nulliparous women from 4–10cm was 1.5 (4.6) hours longer (Plabor patterns were slower for induced TOLAC compared to nulliparous women. Conclusions Labor duration for TOLAC was slower compared to nulliparous labor, particularly for induced labor. By improved understanding of the rates of progress at different points in labor, this new information on labor curves in women undergoing TOLAC, particularly for induction, should help physicians when managing labor.

    Studies of metabolic variation in birds have involved both wild and captive individuals,but few studies have investigated whether captivity directly influences metabolic rates,despite such variation potentially confounding conclusions regarding how metabolic rates respond to the conditions under study.In addition,whether short-term captivity influences metabolic rate repeatability in birds is currently uninvestigated.In this study,we measured Msum (maximal cold-induced metabolic rates) in summer acclimatized American goldfinches Spinus tristis directly after capture from wild populations,after approximately 2 weeks of indoor captivity (Captive 1),and again after an additional 1-2 weeks of captivity (Captive 2).Msum increased significantly (16.9%) following the initial captive period,but remained stable thereafter.Body mass (Mb) also increased significantly (9.2%) during the initial captive period but remained stable thereafter,suggesting that muscle growth and/or remodeling of body composition produced the observed metabolic variation.Mb and Msum were not significantly repeatable between wild and Captive 1 birds,but were significantly repeatable between Captive 1 and Captive 2 groups.These data suggest that caution must be exercised when extrapolating metabolic rates from short-term captive to wild populations.In addition,Msum was a repeatable trait for birds under conditions where mean metabolic rates remained stable,but Msum repeatability disappeared during acclimation to conditions promoting phenotypically flexible metabolic responses.This suggests that the capacity for phenotypic flexibility varies among individuals,and such variation could have fitness consequences.

    Full Text Available     Postmortem cesarean section is a rare event that usually ends up with the mortality of the fetus. A 32-year-old multigravid woman at 34th week of gestation was transferred to the emergency ward due to cardiopulmonary arrest after a traffic accident. A postmortem cesarean section was performed at the 20th minute of the maternal cardio pulmonary arrest and a live fetus was delivered initially. Because of the potential for the survival of a normal infant, obstetricians must consider a cesarean delivery in any pregnant woman that undergone a cardiopulmonary arrest in the third trimester. In this case report. Indications and prognostic factors for fetal well-being in case of a postmortem cesarean section are discussed.

    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. 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. 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. 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.

    This study investigated changes in cesarean delivery rate and cesarean indications in 3 county-level hospitals in rural China. Hospital delivery records in 1997 and 2003 were used to examine the reasons behind the changes. In Chengde County Hospital, the cesarean delivery rate increased from 28% in 1997 to 54% in 2003. The rate increased from 43% in 1997 to 65% in 2003 in Anxian County Hospital and Anxian Maternal and Child Health Hospital. The dramatic increase in cesarean delivery in the study hospitals was associated with a shift from more severe to mild or no clinical indications. The ratio of mild to moderate to severe hypertension increased substantially. More than half of the cephalopelvic disproportion cases were diagnosed prior to labor. The majority of nuchal cord cases were diagnosed without fetal distress. Maternal/family request was the number one cesarean indication in Anxian County Hospital and Anxian MCH Hospital in 2003. Ultrasound evidence of nuchal cord moved from the ninth ranked indication in 1997 to the second in 2003 in Chengde County Hospital.

  9. Evidence of circadian rhythm, oxygen regulation capacity, metabolic repeatability and positive correlations between forced and spontaneous maximal metabolic rates in lake sturgeon Acipenser fulvescens.

    Full Text Available Animal metabolic rate is variable and may be affected by endogenous and exogenous factors, but such relationships remain poorly understood in many primitive fishes, including members of the family Acipenseridae (sturgeons. Using juvenile lake sturgeon (Acipenser fulvescens, the objective of this study was to test four hypotheses: 1 A. fulvescens exhibits a circadian rhythm influencing metabolic rate and behaviour; 2 A. fulvescens has the capacity to regulate metabolic rate when exposed to environmental hypoxia; 3 measurements of forced maximum metabolic rate (MMR(F are repeatable in individual fish; and 4 MMR(F correlates positively with spontaneous maximum metabolic rate (MMR(S. Metabolic rates were measured using intermittent flow respirometry, and a standard chase protocol was employed to elicit MMR(F. Trials lasting 24 h were used to measure standard metabolic rate (SMR and MMR(S. Repeatability and correlations between MMR(F and MMR(S were analyzed using residual body mass corrected values. Results revealed that A. fulvescens exhibit a circadian rhythm in metabolic rate, with metabolism peaking at dawn. SMR was unaffected by hypoxia (30% air saturation (O(2sat, demonstrating oxygen regulation. In contrast, MMR(F was affected by hypoxia and decreased across the range from 100% O(2sat to 70% O(2sat. MMR(F was repeatable in individual fish, and MMR(F correlated positively with MMR(S, but the relationships between MMR(F and MMR(S were only revealed in fish exposed to hypoxia or 24 h constant light (i.e. environmental stressor. Our study provides evidence that the physiology of A. fulvescens is influenced by a circadian rhythm and suggests that A. fulvescens is an oxygen regulator, like most teleost fish. Finally, metabolic repeatability and positive correlations between MMR(F and MMR(S support the conjecture that MMR(F represents a measure of organism performance that could be a target of natural selection.

  10. Cesarean section: science or ritual surgery?

    1991-01-01

    Cesarean section has proven to be a powerful weapon in saving fetal and maternal life when scientific criteria are used in a variety of emergency conditions. However, because of the high incidence of false positive readings with fetal heartrate monitoring, cesareans are often resorted to unnecessarily. In addition, there are other marginal, nonscientific human concerns such as patient and doctor preference, convenience, fear of litigation, wish to avoid pain of labor, and other unspoken and often unrecognized issues that can lead to cesarean section. When cesarean section is resorted to for the above reasons, it becomes ritual surgery. It is time to recognize two sets of criteria for cesarean sections: first, scientific criteria that would save the life of the mother or fetus, or unequivocally guarantee better fetal outcome; and second, nonscientific criteria based on personal preference of doctors and patients. If doctors were candid about these two sets of criteria, patients would not be pressured into cesareans by minor, often transient and misleading, abnormalities on fetal monitors. They would not have to experience ritual surgery unless it was clearly their choice to do so.

    2015-01-01

    Worldwide, there is a rapid increase in deliveries by cesarean section. The large differences among countries, from about 16% to more than 60%, suggest that the cesarean delivery (CD) rate has little to do with evidence-based medicine. In this review, the background for the increasing CD rate is discussed as well as the limited positive effects on neonatal outcome in both term and preterm neonates. Negative effects of CD, including direct maternal morbidity, complications of subsequent pregnancies and iatrogenic early delivery resulting in increased neonatal morbidity, are discussed in addition to long-term implications for the offspring involving altered development of the immune system. The 'battle' to lower the CD rate will be difficult, but we should not forget that women are designed to deliver vaginally and not by cesarean section.

    Approximately one-third of births in the United States are via cesarean delivery (CD). The rate of CD has increased dramatically since the 1990s, reaching a peak of 32.9% in 2009. The increase can be seen among women of all ages and race/ethnicities, in every state, and across all gestational ages. The primary CD rate has increased from 14.5% in 1996 to 23.4% in 2007. Because the primary CD rate has increased and the rate of trial of labor after CD has decreased, the primary cesarean rate has become a major driver in the total CD rate. Also contributing to the high CD rate is an increase in somewhat subjective indications, such as fetal distress or nonreassuring fetal tracing and failure to progress leading to performance of CD in the latent phase of labor. Addressing these factors--as well as focusing on the use of elective induction and management of early labor in the particular subgroup of nulliparous women at term, with singleton fetuses in vertex presentation--may have a significant impact on the total CD rate.

    There is significant increase in proportion of cases with previous cesarean delivery requiring obstetric care. The available literature fails to provide uniform opinion on each woman's characteristics to identify risk of uterine rupture while planning trial of labor after cesarean. To study the association of abnormal lower uterine segment with some of the present and previous obstetric variables including patient characteristics and surgical techniques at previous cesarean operation. Consenting consecutive 96 post-cesarean singleton pregnancies admitting after 36 weeks gestation at the same facility from July 2011 to December 2012 for repeat cesarean, were studied. Only the cases with cephalic presentation and vertex as presenting part, having no placenta previa, polyhydramnios, uterine anomaly or fibroid and those who had previous one lower segment cesarean were recruited. Based on the intra-operative finding the lower uterine segment (LUS) was categorized into those having a normal and abnormal (grades 2-4) LUS. Sonographic assessment of LUS thickness and any abnormalities if any were noted. The findings of abnormal LUS (direct observation at surgery and sonographic impression within a week before surgery) were looked for association with some of the present and previous obstetric variables including patient characteristics and surgical techniques at previous cesarean operation using Student t, Chi square or Fisher's exact test for analysis as appropriate. Receiver operating curve analysis was used to determine the optimal cut off value for prediction of LUS integrity by ultrasound. Of the women recruited for the study, 36 were admitted in early labor and ultrasound evaluation of LUS was performed in 48 of the remaining 60 women admitted antenatal for elective cesarean delivery. There were 38 abnormal LUS (39.6%) with 22 of them (57.9%) graded as 'thinned out LUS'. The incidence of scar dehiscence (grade 3, cases 5) was 5.2% of 96 cases and there were no cases

    Objective: To assess whether Kielland forceps rotational delivery causes a significant increase in maternal or perinatal morbidity in comparison with cesarean delivery in the clinical situation of transverse arrest. Rotational forceps delivery has been reported to have unacceptably high maternal and neonatal complication rates when compared with either spontaneous vaginal delivery or non-rotational forceps delivery. Clinically, however, we considered the more relevant comparison between Kielland rotational forceps delivery and cesarean delivery as these are generally the two modes of delivery for the fetus in transverse arrest.Study Design: The charts of all the mothers delivered by Kielland forceps or cesarean delivery for the main indication of transverse arrest between July 1995 and June 1996 were reviewed. The following were evaluated: Apgar scores at 1 and 5 minutes, cord pH, birth weight, neonatal superficial facial laceration or bruising, bone or nerve injuries, maternal injuries, 3rd and 4th degree perineal or vaginal lacerations, post-partum fever. Statistical analysis was by chi(2) (for Apgar scores), two-tailed Fisher Exact test (for post-partum fever), and t test (for birth weight and cord pH). A P value cesarean deliveries were performed. One-minute Apgar scores of less than or equal to 7 were noted in 11.5% and 6.7% of the forceps and cesarean section groups, respectively (P = NS); mean arterial cord pH was 7.26 for both groups; no cases of post-partum fever were noted in the forceps versus 16% in the cesarean group (P cesarean group, respectively (P cesarean delivery.No significant difference in cord pH and Apgar scores were noted between the two groups. The birth weight was greater and post-partum fever was more common in the cesarean section group. Neonatal facial bruising, temporary facial nerve palsy, and maternal perineal and vaginal lacerations were more common in the forceps groups. This study suggests that rotational forceps may be a

    Analysis of the annual distribution of cesarean sections and indications between 2010 and 2015 in our clinic. Medical records of 10,437 cesarean section patients from a total number of 24,283 deliveries performed at Department of Obstetrics and Gynecology between 2010-2015 were evaluated retrospectively. The indications for Cesarean section were analyzed and compared based on years. The lowest cesarean section rate was 18.67% in 2011 and the highest rate was 24.5% in 2013, and the annual rates were close to each other in this 6-year period (p > 0.05). History of uterine surgery was the indication with the highest rate of 49.52%, while fetal distress was the second most frequent with 12.53%; presentation anomalies were observed as the most frequent third indication with 7.55%, and umbilical cord prolapse was the least frequent indication with 0.33%. Patient education about normal delivery and providing means for pain control during normal delivery, improvement in physical conditions of the clinics, frequent and regular training of the assisting staff with obstetrics physicians are important to diminish the rates of primary cesarean sections. In addition, a normal delivery after a previous cesarean section must be encouraged.

    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

    Full Text Available BACKGROUND: Rising cesarean section (CS rates are a major public health concern and cause worldwide debates. To propose and implement effective measures to reduce or increase CS rates where necessary requires an appropriate classification. Despite several existing CS classifications, there has not yet been a systematic review of these. This study aimed to 1 identify the main CS classifications used worldwide, 2 analyze advantages and deficiencies of each system. METHODS AND FINDINGS: Three electronic databases were searched for classifications published 1968-2008. Two reviewers independently assessed classifications using a form created based on items rated as important by international experts. Seven domains (ease, clarity, mutually exclusive categories, totally inclusive classification, prospective identification of categories, reproducibility, implementability were assessed and graded. Classifications were tested in 12 hypothetical clinical case-scenarios. From a total of 2948 citations, 60 were selected for full-text evaluation and 27 classifications identified. Indications classifications present important limitations and their overall score ranged from 2-9 (maximum grade =14. Degree of urgency classifications also had several drawbacks (overall scores 6-9. Woman-based classifications performed best (scores 5-14. Other types of classifications require data not routinely collected and may not be relevant in all settings (scores 3-8. CONCLUSIONS: This review and critical appraisal of CS classifications is a methodologically sound contribution to establish the basis for the appropriate monitoring and rational use of CS. Results suggest that women-based classifications in general, and Robson's classification, in particular, would be in the best position to fulfill current international and local needs and that efforts to develop an internationally applicable CS classification would be most appropriately placed in building upon this

    Bruschi, David Edward; Barlow, Thomas M.; Razavi, Mohsen; Beige, Almut

    2014-09-01

    We propose a repeat-until-success protocol to improve the performance of probabilistic quantum repeaters. Conventionally, these rely on passive static linear-optics elements and photodetectors to perform Bell-state measurements (BSMs) with a maximum success rate of 50%. This is a strong impediment for entanglement swapping between distant quantum memories. Every time a BSM fails, entanglement needs to be redistributed between the corresponding memories in the repeater link. The key ingredients of our scheme are repeatable BSMs. Under ideal conditions, these turn probabilistic quantum repeaters into deterministic ones. Under realistic conditions, our protocol too might fail. However, using additional threshold detectors now allows us to improve the entanglement generation rate by almost orders of magnitude, at a nominal distance of 1000 km, compared to schemes that rely on conventional BSMs. This improvement is sufficient to make the performance of our scheme comparable to the expected performance of some deterministic quantum repeaters.

    Organ/space surgical site infections (SSIs) are serious complications after cesarean delivery. However, no scoring tool to predict these complications has yet been developed. This study sought to develop and validate a prognostic scoring tool for cesarean organ/space SSIs. Data for case and non-case of cesarean organ/space SSI between January 1, 2007 and December 31, 2012 from a tertiary care hospital in Thailand were analyzed. Stepwise multivariable logistic regression was used to select the best predictor combination and their coefficients were transformed to a risk scoring tool. The likelihood ratio of positive for each risk category and the area under receiver operating characteristic (AUROC) curves were analyzed on total scores. Internal validation using bootstrap re-sampling was tested for reproducibility. The predictors of 243 organ/space SSIs from 4,988 eligible cesarean delivery cases comprised the presence of foul-smelling amniotic fluid (four points), vaginal examination five or more times before incision (two points), wound class III or greater (two points), being referred from local setting (two points), hemoglobin less than 11 g/dL (one point), and ethnic minorities (one point). The likelihood ratio of cesarean organ/space SSIs with 95% confidence interval among low (total score of 0-1 point), medium (total score of 2-5 points), and high risk (total score of ≥6 points) categories were 0.11 (0.07-0.19), 1.03 (0.89-1.18), and 13.25 (10.87-16.14), respectively. Both AUROCs of the derivation and validation data were comparable (87.57% versus 86.08%; p = 0.418). This scoring tool showed a high predictive ability regarding cesarean organ/space SSIs on the derivation data and reproducibility was demonstrated on internal validation. It could assist practitioners prioritize patient care and management depending on risk category and decrease SSI rates in cesarean deliveries.

    To develop a predictive model for risk of cesarean section in pregnant women after induction of labor. A retrospective cohort study was conducted of 861 induced labors during 2009, 2010, and 2011 at Hospital "La Mancha-Centro" in Alcázar de San Juan, Spain. Multivariate analysis was used with binary logistic regression and areas under the ROC curves to determine predictive ability. Two predictive models were created: model A predicts the outcome at the time the woman is admitted to the hospital (before the decision to of the method of induction); and model B predicts the outcome at the time the woman is definitely admitted to the labor room. The predictive factors in the final model were: maternal height, body mass index, nulliparity, Bishop score, gestational age, macrosomia, gender of fetus, and the gynecologist's overall cesarean section rate. The predictive ability of model A was 0.77 [95% confidence interval (CI) 0.73-0.80] and model B was 0.79 (95% CI 0.76-0.83). The predictive ability for pregnant women with previous cesarean section with model A was 0.79 (95% CI 0.64-0.94) and with model B was 0.80 (95% CI 0.64-0.96). For a probability of estimated cesarean section ≥80%, the models A and B presented a positive likelihood ratio (+LR) for cesarean section of 22 and 20, respectively. Also, for a likelihood of estimated cesarean section ≤10%, the models A and B presented a +LR for vaginal delivery of 13 and 6, respectively. These predictive models have a good discriminative ability, both overall and for all subgroups studied. This tool can be useful in clinical practice, especially for pregnant women with previous cesarean section and diabetes.

    Full Text Available Backgound and Objectives: Considering the use of active surveillance assists in infection identification and the need for studies that use Surgical Risk Index (SRI for assessment of Surgical Site Infection (SSI in cesareans, this study aims to determine the incidence of SSI and analyze the applicability of SRI in the prediction of SSI in women in the postpartum period after being submitted to a cesarean section at a university hospital between April 2012 and March of 2013. Methods: Prospective cohort study. Information notifying SSI by active surveillance was collected daily from the medical records. After hospital discharge, the mothers were contacted through telephone calls to identify infection criteria within 30 days after the cesarean. Descriptive and comparative analyses were performed. The chi-square test was used to compare groups. Results: 737 cesareans were performed. Telephone contact was achieved with 507 (68.8% women up to 30 days postpartum, with loss of follow-up of 230 cases (31.2%. The medical consultation in the post-partum period occurred with 188 (37.08% women, with whom telephone contact was obtained, on average, 17.28 days (SD=8.39 after delivery. It was verified that 21 patients met the criteria for SSI, with a 4.14% rate. A total of 12 cases (57.1% were classified as superficial SSI, 5 (23.8% as deep and 4 (19.1% as infection of organs and cavities. The SRI and its risk variables were not associated with SSI in patients submitted to cesarean sections. Conclusion: The SRI and the risk variables included in this index were not associated to SSI in patients submitted to cesarean sections.

    The objective of this study was to examine if patients with "early rupture of membranes (ROM)" after spontaneous onset of labor are at increased risk of cesarean section. The rate of cesarean section was examined in 447 term singleton nulliparas who were admitted after the spontaneous onset of labor. The cases were divided into 2 groups: (1) "early ROM", defined as ROM at a cervical dilatation or=4 cm (n=338). (1) "Early ROM" occurred in 24.4% of the cases and the overall cesarean section rate was 5.6%; (2) there were no significant differences in the clinical characteristics including prepregnancy BMI, proportion of complicated pregnancies, total duration of labor, proportion of regional anesthesia, gestational age at delivery, and birthweight between the two groups of cases. However gravidas with "early ROM" were of advanced maternal age and had less cervical dilation on admission, shorter duration of 1st stage of labor, and more frequent use of oxytocin augmentation; (3) patients with "early ROM" had a threefold higher rate (11.9% vs. 3.6%) of cesarean section and a fourfold higher rate (11.9% vs. 3.0%) of cesarean section due to failure of progress than did those with "late ROM" (ponset of labor is a risk factor for cesarean section in term singleton nulliparas. 2009 Elsevier Ireland Ltd.

    Women who undergo cesarean birth might have an increased risk for poor mental health after childbirth, possibly because of maternal and neonatal physical problems, low parental confidence, and decreased levels of oxytocin. However, this relationship remains controversial and requires further examination. The study aimed to examine the effect of cesarean birth on postpartum stress, anxiety, and depression. This nationwide population-based cohort study was conducted using the Taiwan National Health Insurance Database. A total of 12 619 women who underwent cesarean birth and 12 619 control women who underwent vaginal birth were matched by propensity score based on age, socioeconomic status, residential urbanicity, antepartum comorbidity, and index year of delivery. We compared the incidence of stress, anxiety, and depression during the first postpartum year between cesarean and comparison groups by calculating incidence rate ratios (IRRs). The cesarean group showed a significantly higher risk for stress symptoms (IRR 1.4 [95% confidence interval {CI} 1.02-1.92]), but not anxiety (IRR 1.14 [95% CI 0.95-1.38]) or depression (IRR 1.32 [95% CI 0.94-1.87]), although the IRRs were also greater than one. The cesarean group had a significantly higher risk of any of the above-listed three disorders than the comparison group (incidence 27.6 vs 23.4 per 1000 person-years; IRR 1.18 [95% CI 1.01-1.38]). Cesarean birth was associated with an increased risk of postpartum stress symptoms. Health professionals should avoid unnecessary cesarean birth, pay attention to women who deliver by cesarean, and intervene appropriately in an attempt to improve mental health among postpartum women. © 2017 Wiley Periodicals, Inc.

    Objective: To compare single-dose antibiotic prophylaxis (cefotetan 1 g vs cefoxitin 2 g) in various subpopulations based upon risk factors for postsurgical infection following cesarean section.Methods: Patients undergoing cesarean section from April 1993 through March 1994 were included in a retrospective analysis if either of the above antibiotics were administered, surgery was non-emergent, gestational age was less than 32 weeks, absence of fever or prior antibiotics therapy within 72 hours, and no history of organ transplantation or HIV. Cases classified as high risk for infection: IDDM, obesity, autoimmune disease, sickle cell disease, or corticosteroid use. Cases classified as high risk for endometritis (any 2 factors): labor >12 hours, >4 vaginal examinations, ruptured membranes >9 hours, and internal fetal monitor. Cases were separated into 4 groups: elective vs non-elective, low vs high surgical risk. A chi(2) analysis was used to test for differences in infection rates between groups (P cesarean sections, 385 met criteria for inclusion. Non-elective cases accounted for 77% of cases. Postsurgical infection rate was greater in non-elective cases, 7.4%, vs elective cases, 3.0% (P =.056) as was the rate of endometritis (3.2% vs 1.2%, P =.185). No differences were noted based on antibiotic regimen. Postsurgical infection rate was greater for 28 cases at high risk for both surgical infection and endometritis (17.9%) when compared to all 357 other cases (4.5%), P =.003. No difference was noted for endometritis. Of the 28 cases 28.6% of patients treated with cefoxitin and 7.1% of cases treated with cefotetan developed postsurgical infection (P =.13).Conclusion: Overall cefoxitin and cefotetan provided equivalent clinical outcome. A small subset of patients with multiple risk factors for infection may benefit from cefotetan.

    All postpartum women, including those who are breastfeeding or have had a cesarean section, appear potentially suited to intrauterine contraception, a long acting reversible contraceptive (LARC). Like any other method used after delivery, it should not interfere with lactation or be affected by cesarean section. We searched the MEDLINE, PubMed, Popline, Google Scholar, and Clinicaltrials.gov databases from January 1968 through to December 2012. Studies were included if they reported event rates in women who had a cesarean section and event rates and clinical outcomes in lactating women or their infants in the breastfeeding group. Summary odds ratios were not calculated because of the diverse methods of reporting event rates in the cesarean section group and the heterogeneity of the results in the breastfeeding group. We found 26 articles on event rates in interval and post-placental intrauterine device (IUD) use, and 18 on event rates and clinical outcomes in breastfeeding IUD users. Four prospective studies and one retrospective study showed an increased expulsion rate in interval insertion. There were 19 studies, of which five were controlled in post-placental IUD insertion after cesarean section. Four studies had expulsion rates of 10 or more per 100 woman-years of use and 15 expulsion rates below 10 per 100 woman-years of use. Three studies showed that event rates for lactating IUD users are the same as those for non-lactating users. Fifteen controlled studies showed that the IUD had no effect on milk production and seven of these showed no effect on infant growth. Pharmacovigilance databases report an increased rate of IUD perforations in lactating women, while the event rate studies report that insertion is generally easier and less painful than expected. These were uncontrolled reports. The IUD is a long-acting reversible method of contraception with expulsion rates of 5-15 per 100 woman-years of use when used as a post-placental method immediately after

    The objective of this study was to assess the influence of a teaching plan consisting of didactic teaching and repeated simulations on the performance of anesthesia residents in the management of general anesthesia (GA) for emergency Cesarean delivery (CD). Twenty-one postgraduate year 2 (PGY2) and 3 (PGY3) anesthesia residents from the University of Toronto were recruited in this prospective cohort study. All participants received didactic teaching in the management of GA for emergency CD, which was followed one week later by assessment of performance in the same scenario using a high-fidelity simulator. Another simulation assessment was repeated two months later in the same scenario. All simulation video recordings were assessed by two blinded experts using a validated checklist and an Anaesthetists' Non-Technical Skills (ANTS) scale in order to rate their technical and non-technical skills, respectively. The participants' performance (based on the above scales) in the two simulation sessions were then compared. Nineteen residents completed both simulation sessions. There was an improvement in the mean (SD) weighted checklist score from 64.5% (7.1%) in session 1 to 76.7% (6.7%) in session 2 (P technical skills but also the non-technical skills of residents, most likely due to the feedback received after the first simulation session. Repeated simulation sessions may help prepare residents to deal more effectively with similar critical situations in clinical practice with minimum errors.

    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 evaluate the association between the prior use of a sodium hyaluronate-carboxycellulose adhesion barrier and the incision-to-delivery time and adhesion scores at first repeat cesarean delivery. In this cohort study, intraoperative data were prospectively collected at the time of the study participants' first repeat cesarean delivery. Subsequent retrospective chart review of each patient's primary cesarean operative note was then performed to determine whether hyaluronate-carboxycellulose barrier film had been used. The primary outcome was incision-to-delivery time. Secondary outcomes were adhesion grade and blood loss. A total of 97 patients were analyzed; 71 did not have hyaluronate-carboxycellulose barrier film used during their primary cesarean and 26 did. Mean ± standard deviation incision-to-delivery time was 9.5 ± 4.3 minutes in the no hyaluronate-carboxycellulose barrier film group and 10.6 ± 5.8 minutes in the hyaluronate-carboxycellulose barrier film group (P=.8). Average blood loss was 564 ± 255 mL and 563 ± 246 mL, respectively (P=.4). There was no difference between the mean fascia adhesion scores (1.45 compared with 1.31 Z -1.06, P=.29) and mean intraperitoneal adhesion scores (1.11 compared with 0.92 Z -1.09, P=.27). Our sample size yielded a power of 91% to detect a 5-minute difference in delivery times and 99% for a 1-point difference in adhesion scores. Our study showed no difference in the delivery time, blood loss, or adhesion scores at first repeat cesarean delivery between women who had hyaluronate-carboxycellulose barrier film placed at the time of their primary cesarean delivery and those who did not. : II.

    Placenta accreta (PA), a severe complication during delivery, is closely linked with massive hemorrhage which could endanger the lives of both mother and baby. Moreover, the incidence of PA has increased dramatically with the increasing rate of cesarean deliveries in the past few decades. Therefore, studies evaluating the effects of different perioperative managements based on different modalities in the treatment of PA are necessary. Among the numerous treatment measures, prophylactic abdominal aortic balloon occlusion (AABO) in combination with cesarean section for PA seems to be more advantageous than others. However, up to now, all studies on AABO were almost retrospective. Current evidence is insufficient to recommend for or against routinely using the AABO technology for control intraoperative hemorrhage in patients with PA. Thus, we hope to carry out a prospective, randomized controlled trial (RCT) study to confirm the effectiveness of the AABO technology in patients with PA. This trial is an investigator-initiated, prospective RCT that will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. A total of 170 parturients with PA undergoing cesarean section will be randomized to receive either AABO in combination with cesarean section or the traditional hysterectomy following cesarean section. The primary outcome is estimated blood loss. The most important secondary outcome is the occurrence of cesarean hysterectomy during delivery; others include blood transfusion volume, operating time, neonate's Apgar scores (collected at 1, 5 and 10 min), length of stay in intensive care unit, total hospital stay, and balloon occlusion-relative data. This prospective trial will test the superiority of AABO in combination with cesarean section compared to the traditional hysterectomy following cesarean section for parturients with PA. It may provide strong evidence

  14. Vaginal birth after cesarean section: an update on physician trends and patient perceptions.

    The increased number of women having a vaginal birth after a cesarean section can be attributed to changing physician trends. Women eligible for vaginal birth after cesarean section include those with previous low vertical incisions, multiple previous incisions and even unknown scars, regardless of the method of closure or previous indication. Limited data suggest that in carefully selected women a current twin gestation, breech presentation, or the presence of fetal macrosomia are not contraindications for a trial of labor, in the presence of a uterine scar. Changing trends in the management of labor may also contribute to an increase in successful trial of labor with the use of oxytocin for the induction or augmentation of labor, the administration of epidural anesthesia for pain relief, and the instillation of prostaglandin E2 gel for cervical ripening. External cephalic version and amnioinfusion may also be reasonable alternatives in appropriately selected cases. Despite the documented safety and success of vaginal birth after cesarean section, and the lack of increased morbidity of failed trial of labor, 50% of women who are eligible for vaginal birth after cesarean section will decline an attempt, even after extensive counseling and encouragement. Patient resistance, largely attributed to the fear and inconvenience of labor, is still a major deterrent to a further rise in vaginal birth after cesarean section rates.

    We analysed the efficacy and safety of double-balloon catheter for cervical ripening in women with a previous cesarean section and which were the most important variables associated with an increased risk of repeated cesarean delivery. We designed an observational retrospective study of 418 women with unfavourable cervices (Bishop Score cesarean delivery, and induction of labour with a double-balloon catheter. Baseline maternal data and perinatal outcomes were recorded for a descriptive, bivariate, and multivariate analysis. A p value cesarean section were dystocia in the previous pregnancy (OR 1.744; CI 95% 1.066-2.846), the absence of previous vaginal delivery (OR 2.590; CI 95% 1.066-6.290), suspected fetal macrosomia (OR 2.410; CI 95% 0.959-6.054), and duration of oxytocin induction period (OR 1.005; CI 95% 1.004-1.006). The area under the curve was 0.789 (p cesarean delivery and unfavourable cervix. In our study, most women could have a vaginal delivery in spite of their risk factors for cesarean delivery. A multivariate model based on some clinical variables has moderate predictive value for intrapartum cesarean section.

    2013-06-01

    Cesarean delivery (CD) is the second most commonly performed surgery in the United States. As such, prevention of complications associated with this procedure is a top priority in nursing care. Nurses at the study institution perceived that postcesarean patients experienced increased urinary retention after use of spinal morphine for postoperative pain relief. This observation prompted a review of the literature indicating that limited research had been conducted in this area. The purpose of this study was to explore the relationship of postelective CD urinary retention and dose of spinal morphine. A retrospective, quasi-experimental, three-group design was used. Records of 150 patients, ages 17 to 39, undergoing elective primary or repeat CD were examined. Morphine doses included 100, 150, and 200 mcg. No statistically significant differences were found between the three groups.

Methods: Peer-reviewed articles were systematically searched on PubMed. The following Chinese databases were comprehensively searched: the China National Knowledge Infrastructure, Wanfang, and the VIP information. The databases were searched from inception to September 1, 2013. Two reviewers independently screened the titles and abstracts for eligibility. Full texts of eligible papers were reviewed, where relevant references were hand-searched and reviewed. Findings: Sixty articles were included from PubMed, 17 articles were intentionally picked out from Chinese journals, and five additional articles were added, for a total of 82 articles for the analysis. With a current national rate near 40%, the literature consistently reported a rapid rise of cesarean sections in the People’s Republic of China in the past decades, irrespective of where people lived or their socioeconomic standing. Nonclinical factors were considered as the main drivers fueling the rise of cesareans in the People’s Republic of China. There was a lively debate on whether women’s preferences or providers’ distorted financial incentives affected the rise in cesarean sections. However, recent evidence suggests that it might be the People’s Republic of China’s health development approach – focusing on specialized care and marginalizing primary care – that is playing a role.

    Full Text Available Youssef’s syndrome is characterized by cyclic hematuria (menouria, absence of vaginal bleeding (amenorrhea, and urinary incontinence due to vesicouterine fistula (VUF, the least common of the urogynecological fistulas. Youssef’s syndrome has a variable clinical presentation. A vesicouterine fistula is an abnormal pathway between the bladder and the uterus. The most common cause is lower segment Cesarean section. Conservative treatment may be appropriate in some cases, but surgery is the definitive treatment. Vesicouterine fistula should be suspected in cases presenting with urinary incontinence even years after Cesarean section. Diagnostic tests as well as necessary appropriate surgery should be performed on cases with suspected vesicouterine fistula. We present a 40-year-old multiparous woman with vesicouterine fistula after primary Cesarean section; she presented with urinary incontinence, hematuria, and amenorrhea 1 year after the birth. Here, we discuss our case with the help of previously published studies found in the literature.

    Full Text Available Cesarean scar pregnancies (CSPs are a rare complication of previous cesarean deliveries. As cesarean section rates continue to increase worldwide, the incidence of CSPs is likely to rise as well. The diagnosis and management of CSPs pose challenging problems to clinicians. Early accurate diagnosis is crucial, as CSP is a life-threatening emergency that can lead to potentially catastrophic consequences such as uterine rupture, hemorrhage, loss of fertility and maternal death. There is no general consensus, however, regarding the best means of management. Various case reports and case series have reported successful outcomes with medical treatment, surgical intervention, interventional radiology, as well as a combination of methods. We present a case series of CSPs managed in our center, a tertiary obstetrics and gynecology hospital. All were treated primarily by conservative and fertility-sparing surgical methods. We have also included a short review of the current literature on this rare but important condition.

    Delivery by means of cesarean section has been associated with increased risk of childhood immune-mediated diseases, suggesting a role of early bacterial colonization patterns for immune maturation. We sought to describe the influence of delivery method on gut and airway colonization patterns in the first year of life in the Copenhagen Prospective Studies on Asthma in Childhood2010 (COPSAC2010) birth cohort. Seven hundred children from the COPSAC2010 birth cohort participated in this analysis. Fecal samples were collected at age 1 week, 1 month, and 1 year, and hypopharyngeal aspirates were collected at age 1 week, 1 month, and 3 months and cultured for bacteria. Detailed information on delivery method, intrapartum antibiotics, and lifestyle factors was obtained by personal interviews. Seventy-eight percent of the children were born by means of natural delivery, 12% by means of emergency cesarean section, and 9% by means of elective cesarean section. Birth by means of cesarean section was significantly associated with colonization of the intestinal tract by Citrobacter freundii, Clostridium species, Enterobacter cloacae, Enterococcus faecalis, Klebsiella oxytoca, Klebsiella pneumoniae, and Staphylococcus aureus at age 1 week, whereas colonization by Escherichia coli was associated with natural birth. At age 1 month, these differences were less prominent, and at age 1 year, they were not apparent, which was confirmed by means of multivariate data-driven partial least squares analyses. The initial airway microbiota was unaffected by birth method. Delivery by means of cesarean section was associated with early colonization patterns of the neonatal gut but not of the airways. The differences normalized within the first year of life. We speculate that microbial derangements, as indicated in our study, can demonstrate a possible link between delivery by means of cesarean section and immune-mediated disease.

    Four million deliveries occur annually in the United States, and obstetric care has traditionally constituted a substantial portion of medical costs for young women, as well as being a major source of uncompensated care. The economic implications of a large shift in the mode of delivery are potentially important. This article reviews the relevant economic issues surrounding elective cesarean section and cesarean section at maternal request, summarizes the methodological quality and results of current literature on the topic, and presents recommendations for further study.

    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.

    This study was done to compare the rates of hemolysis and repeated sampling in blood samples obtained by a syringe needle versus a vacuum tube needle. A randomized, prospective study was used to evaluate the differences between the two blood sampling methods. The study group consisted of patients seen in the emergency department (ED) for blood sampling to determine electrolyte level. ED patients were randomly assigned to either the syringe group or the vacuum tube group. All blood samples were collected by experienced ED nurses and hemolysis was determined by experienced laboratory technologists. Data were analyzed using Fisher's exact test and binary logistic regression. One hundred forty-five valid samples were collected (74 in the syringe group versus 71 in the vacuum tube group). 5 of 74 (6.8%) blood samples in the syringe group and 8 of 71 (11.3%) in the vacuum tube group hemolyzed. Repeated blood sampling occurred for 2 of 74 (2.7%) and 3 of 71 (4.2%) in each group respectively. There were no significant differences in rates of hemolysis and repeated sampling between two groups (B=1.97, p=.204; B=2.36, p=.345). Venipuncture with syringe needles can be recommended for ED nurses to obtain blood samples.

    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.

    Full Text Available BACKGROUND: Cesarean delivery is the most common inpatient surgery in the United States, where 1.3 million cesarean sections occur annually, and rates vary widely by hospital. Identifying sources of variation in cesarean use is crucial to improving the consistency and quality of obstetric care. We used hospital discharge records to examine the extent to which variability in the likelihood of cesarean section across US hospitals was attributable to individual women's clinical diagnoses. METHODS AND FINDINGS: Using data from the 2009 and 2010 Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project--a 20% sample of US hospitals--we analyzed data for 1,475,457 births in 1,373 hospitals. We fitted multilevel logistic regression models (patients nested in hospitals. The outcome was cesarean (versus vaginal delivery. Covariates included diagnosis of diabetes in pregnancy, hypertension in pregnancy, hemorrhage during pregnancy or placental complications, fetal distress, and fetal disproportion or obstructed labor; maternal age, race/ethnicity, and insurance status; and hospital size and location/teaching status. The cesarean section prevalence was 22.0% (95% confidence interval 22.0% to 22.1% among women with no prior cesareans. In unadjusted models, the between-hospital variation in the individual risk of primary cesarean section was 0.14 (95% credible interval 0.12 to 0.15. The difference in the probability of having a cesarean delivery between hospitals was 25 percentage points. Hospital variability did not decrease after adjusting for patient diagnoses, socio-demographics, and hospital characteristics (0.16 [95% credible interval 0.14 to 0.18]. A limitation is that these data, while nationally representative, did not contain information on parity or gestational age. CONCLUSIONS: Variability across hospitals in the individual risk of cesarean section is not decreased by accounting for differences in maternal diagnoses. These

  13. Requests for cesarean deliveries: The politics of labor pain and pain relief in Shanghai, China.

    Science.gov (United States)

    Wang, Eileen

    2017-01-01

    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.

    Aim of this article is to examine if we could identify factors that predict cesarean section and instrumental vaginal delivery in women who had a successful external cephalic version. We used data from a previous randomized trial among 25 hospitals and their referring midwife practices in the Netherlands. With the data of this trial, we performed a cohort study among women attempting vaginal delivery after successful ECV. We evaluated whether maternal age, gestational age, parity, time interval between ECV and delivery, birth weight, neonatal gender, and induction of labor were predictive for a vaginal delivery on one hand or a CS or instrumental vaginal delivery on the other hand. Unadjusted and adjusted odds ratios were calculated with univariate and multivariate logistic regression analysis. Among 301 women who attempted vaginal delivery after a successful external cephalic version attempt, the cesarean section rate was 13% and the instrumental vaginal delivery rate 6%, resulting in a combined instrumental delivery rate of 19%. Nulliparity increased the risk of cesarean section (OR 2.7 (95% CI 1.2-6.1)) and instrumental delivery (OR 4.2 (95% CI 2.1-8.6)). Maternal age, gestational age at delivery, time interval between external cephalic version and delivery, birth weight and neonatal gender did not contribute to the prediction of failed spontaneous vaginal delivery. In our cohort of 301 women with a successful external cephalic version, nulliparity was the only one of seven factors that predicted the risk for cesarean section and instrumental vaginal delivery.

    To investigate changes in uterine flexion after cesarean delivery in comparison with vaginal delivery, and their relationship with the presence of deficient cesarean section scars. In 147 women who had a vaginal delivery and 101 women who had a cesarean delivery, transvaginal ultrasonographic photographs of the uterus were obtained at the first trimester of pregnancy and at 1 month postpartum, and they were reviewed to determine changes in uterine flexion. The presence of a deficient cesarean section scar was also reviewed in women with a cesarean section. Changes in uterine flexion were observed more frequently among the woman with a cesarean delivery than in those with a vaginal delivery. The incidence of post-flexed uterus during puerperium tended to increase depending on the number of cesarean sections the woman had undergone. In the women with a cesarean section, changes in uterine flexion were more frequently observed in the women with a deficient cesarean section scar than in those without one. Changes in uterine flexion after birth occurred more frequently in the women who had a cesarean delivery than in those who had a vaginal delivery, especially in the presence of a deficient cesarean section scar.

    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

    Objective To investigate the early diagnosis and treatment of cesarean sear pregnancy (CSP).Methods Clinical data of 28 patients with CSP in Peking Union Medical College Hospital from January 1994 to April 2007, including age, interval from the last cesarean delivery to diagnosis, clinical presentation, location of the le-sion, process of diagnosis and treatment, outcome, and follow-up, were retrospectively analyzed.Results CSP constituted 1.05% of all ectopic pregnancies, and the ratio of CSP to pregnancy was 1:1 221. Themean age of the group was 31.4 years. Twenty-six women had only one prior cesarean delivery. The interval from the last cesarean delivery to diagnosis ranged from 4 months to 15 years. The most common presenting symptoms of CSP were amenorrhoea and vaginal bleeding. Seventeen cases were misdiagnosed as early intrauterine pregnancies and 2 weremisdiagnosed as gestational trophoblastic tumor. The other 9 were diagnosed definitely before treatment. The diagnosis was made based on cesarean delivery history, gynecologic examination, ultrasound, and magnetic resonance imaging (MRI). The treatment of CSP included systemic or local methotrexate administration, conservative surgery, and hyster-ectomy. The conservative treatment was successful in 24 eases. All of the 28 women were cured through individual ther-apies.Conclusions CSP is rare and usually misdiagnosed as other diseases. Ultrasound is valuable for diagnosing CSP,and MRI can be used as an adjunct to ultrasound scan. Early diagnosis offers the options of conservative treatment and greatly improves the outcome of patients. Individual therapy is strongly recommended.

    This paper uses an unbalanced panel dataset to evaluate how repeated job search services (JSS) and personal characteristics affect the employment rate of the prime-age female welfare recipients in the State of Washington. We propose a transition probability model to take into account issues of sample attrition, sample refreshment and duration dependence. We also generalize Honoré and Kyriazidou's [Honoré, B.E., Kyriazidou, E., 2000. Panel data discrete choice models with lagged dependent variables. Econometrica 68 (4), 839-874] conditional maximum likelihood estimator to allow for the presence of individual-specific effects. A limited information test is suggested to test for selection issues in non-experimental data. The specification tests indicate that the (conditional on the set of the confounding variables considered) assumptions of no selection due to unobservables and/or no unobserved individual-specific effects are not violated. Our findings indicate that the first job search service does have positive and significant impacts on the employment rate. However, providing repeated JSS to the same client has no significant impact. Further, we find that there are significant experience-enhancing effects. These findings suggest that providing one job search services training to individuals may have a lasting impact on raising their employment rates.

    Despite impressive progress in perinatology, fetal injuries from arrest of the shoulders at birth have not decreased in recent decades. Based upon sporadic reports of Erb's palsy in neonates born by Cesarean section, some obstetricians embraced the theory recently that brachial plexus lesions often derive from spontaneous forces acting in utero. Having reviewed three hundred malpractice claims involving fetal injuries attributed to shoulder dystocia at birth, the authors found only two cases connected with abdominal deliveries. One followed manual replacement of the already delivered fetal head into the pelvis after sequential vacuum and forceps procedures and failed manual extraction of the body. The other was an elective repeat Cesarean section where extensive adhesions limited the available space for the lower segment transverse uterine incision. Coincidental fracture of the clavicle and absence of contractures or deformities indicated that the brachial plexus injury was acute, having resulted from forceful traction at delivery.

    Full Text Available Established during infancy, our complex gut microbial community is shaped by medical interventions and societal preferences, such as cesarean section, formula feeding, and antibiotic use. We undertook this study to apply the significance analysis of microarrays (SAM method to quantify changes in gut microbial composition during later infancy following the most common birth and postnatal exposures affecting infant gut microbial composition. Gut microbiota of 166 full-term infants in the Canadian Healthy Infant Longitudinal Development birth cohort were profiled using 16S high-throughput gene sequencing. Infants were placed into groups according to mutually exclusive combinations of birth mode (vaginal/cesarean birth, breastfeeding status (yes/no, and antibiotic use (yes/no by 3 months of age. Based on repeated permutations of data and adjustment for the false discovery rate, the SAM statistic identified statistically significant changes in gut microbial abundance between 3 months and 1 year of age within each infant group. We observed well-known patterns of microbial phyla succession in later infancy (declining Proteobacteria; increasing Firmicutes and Bacteroidetes following vaginal birth, breastfeeding, and no antibiotic exposure. Genus Lactobacillus, Roseburia, and Faecalibacterium species appeared in the top 10 increases to microbial abundance in these infants. Deviations from this pattern were evident among infants with other perinatal co-exposures; notably, the largest number of microbial species with unchanged abundance was seen in gut microbiota following early cessation of breastfeeding in infants. With and without antibiotic exposure, the absence of a breast milk diet by 3 months of age following vaginal birth yielded a higher proportion of unchanged abundance of Bacteroidaceae and Enterobacteriaceae in later infancy, and a higher ratio of unchanged Enterobacteriaceae to Alcaligenaceae microbiota. Gut microbiota of infants born

    Objective To review the current knowledge on the prevalence, reasons, and consequences of cesarean sections in the People’s Republic of China. Methods Peer-reviewed articles were systematically searched on PubMed. The following Chinese databases were comprehensively searched: the China National Knowledge Infrastructure, Wanfang, and the VIP information. The databases were searched from inception to September 1, 2013. Two reviewers independently screened the titles and abstracts for eligibility. Full texts of eligible papers were reviewed, where relevant references were hand-searched and reviewed. Findings Sixty articles were included from PubMed, 17 articles were intentionally picked out from Chinese journals, and five additional articles were added, for a total of 82 articles for the analysis. With a current national rate near 40%, the literature consistently reported a rapid rise of cesarean sections in the People’s Republic of China in the past decades, irrespective of where people lived or their socioeconomic standing. Nonclinical factors were considered as the main drivers fueling the rise of cesareans in the People’s Republic of China. There was a lively debate on whether women’s preferences or providers’ distorted financial incentives affected the rise in cesarean sections. However, recent evidence suggests that it might be the People’s Republic of China’s health development approach – focusing on specialized care and marginalizing primary care – that is playing a role. Although 30 articles were identified studying the consequences of cesareans, the methodologies are in general weak and the themes are out of focus. Conclusion The overuse of cesareans is rising alarmingly in the People’s Republic of China and has become a real public health problem. No consensus has been made on the leverage factors that drive the cesarean epidemic, particularly for those nonclinical factors. The more macro level structural factors may have played a part

    Patient choice cesarean or cesarean by maternal request/ demand is a controversial issue. The medical literature contains evidence based data on the medical aspects of patient choice cesarean, risks and benefits to the mother and her newborn. Fewer studies focused on the social and legal aspects of patient choice cesarean. This opinion paper discusses the social and legal aspects of patient choice cesarean.

    1996. The cases were 153 women whose second delivery was through a cesarean section and the controls were 203 women whose second delivery was vaginal. For analysis, means, standard deviation, Student's t-test, Mann-Whitney test, chi² test and odds ratio (OR with 95% CI for each factor possibly associated with cesarean section on the second delivery were used. Results: the route of the second delivery was vaginal for 57% of the women. Among the several variables studied, those which showed to be significantly associated with a cesarean section on the second delivery were: higher maternal age (for women over 35 years, OR = 16.4, previous abortions (OR = 2.09, induced labor (OR = 3,83, premature rupture of membranes (OR = 2.83, not having an epidural analgesia performed during labor (OR = 5.3, the finding of some alteration in fetal well-being (OR = 2.7 and the delivery occurring during the afternoon (OR = 1.92. Conclusions: these results indicate that the factors associated with the repetition of cesarean section in women with a previous scar of cesarean section in this population are predominantly medical; however, there is still the possibility of proposing interventions directed to decreasing the rates of repeated cesarean sections.

    Objective To describe facility-based decision-making for women with one prior cesarean delivery (CD) in a resource-limited setting and to characterize maternal and perinatal outcomes in these groups. Methods One year retrospective study of women with one prior CD delivering at Korle-Bu Teaching Hospital (KBTH), Ghana. Women were categorized into three groups based on initial plan of management on admission [trial of labor after cesarean (TOLAC), emergency repeat CD (EMCD) or non-emergent repeat CD (RCD)]. Characteristics and outcomes across these groups were then compared. Results During the study period, 1247 women with one prior CD delivered at KBTH, of which 377 (30.2%) were triaged to RCD, 439 (35.2%) to EMCD and 431 (34.6%) to TOLAC. Twelve uterine ruptures and no maternal deaths occurred. Perinatal mortality was 4.2% (n = 52). Compared to the RCD group, the TOLAC group had a lower risk for maternal adverse events (aOR 0.3, 95% CI 0.1-1.0; p = 0.04) and non-significant higher risk of perinatal adverse events (aOR 1.6, 95% CI 0.7-3.3; p = 0.25). Compared to women triaged to RCD, the EMCD group had a non-significant increase in risk of maternal adverse events (aOR 1.6, 95% CI 0.8-3.5; p = 0.2) and a significantly higher rate of perinatal adverse events (aOR 2.4, 95% CI 1.2-4.9; p = 0.01). Conclusions for Practice Women triaged to EMCD at admission are different when compared to women allowed a TOLAC or offered a non-emergent RCD. These women bear increased rates of adverse outcomes and should be considered as a separate group for analysis in future studies conducted in similar settings.

    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.

    To assess the effects of mechanical dilatation of the cervix during cesarean section on postoperative morbidity. A total of 447 women with elective cesarean section were included in the Dondi trial (Dilatation or no dilatation of the cervix during cesarean section). The primary outcome measure of this randomized controlled trial was postpartum hemorrhage (PPH) within 6 weeks. Infectious morbidity (puerperal fever, endometritis, wound infection, and urinary tract infection), blood loss (need for blood transfusion or change in hemoglobin levels), and operating time were also evaluated. The rate of PPH within 6 weeks was not different between the two groups [dilatation group: 5 (2.4 %), no dilatation group: 3 (1.2 %), p = 0.479]. Infectious morbidity, blood loss, and operating time were not diverse as well. The only significant difference between the two groups was the rate of retained products of conception with fewer cases after cervical dilatation (0 versus 6.2 %, p cesarean section compared with no dilatation of the cervix did not influence the risk of postpartum hemorrhage. However, there were fewer cases with retained products of conception after dilatation.

    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 obese women, there was evidence of effect modification by emergency CD. Compared with nonobese women, neither super obese women undergoing nonemergency CD (ARR, 1.13; 95% CI, 0.84 to 1.52) nor those undergoing emergency CD (ARR, 0.59; 95% CI, 0.32 to 1.10) had an increased risk of intraoperative complication. In contrast to the risk for postcesarean complications, the risk of intraoperative complication does not appear to be increased in obese women, even among those with super obesity.

    Intraoperative awareness is defined as the spontaneous recall of an event occurring during general anesthesia. A move away from rigid anesthetic protocols, which were designed to limit drug transmission across the placenta, has reduced the incidence of awareness during cesarean delivery to approximately 0.26%. Nevertheless, it remains an undesirable complication with potential for the development of posttraumatic stress disorder. Assessing depth of anesthesia remains a challenge for the anesthesia provider as clinical signs are unreliable and there is no sensitive and specific monitor. Bispectral Index monitoring with the goal of scores awareness. Induction drugs vary in their ability to produce amnesia and the period of hypnotic effect is affected by the rate at which they are redistributed. After initiation of anesthesia, volatile anesthetics should be administered to a target of 0.7 minimum alveolar anesthetic concentration, which has been shown to consistently achieve mean Bispectral Index scores awareness during emergency cesarean delivery. In the absence of fetal compromise, there is no rationale for an inspired oxygen concentration above 0.33. Deeper levels of anesthesia reduce the incidence of awareness; current evidence does not suggest an increased risk of tocolysis or fetal morbidity.

    To quantify needle migration and dosimetric impact in high-dose-rate brachytherapy for prostate cancer and propose a threshold for needle migration. Twenty-four high-risk prostate cancer patients treated with an HDR boost of 2 × 8.5 Gy were included. Patients received an MRI for planning (MRI1), before (MRI2), and after treatment (MRI3). Time from needle insertion to MRI3 was ∼3 hours. Needle migration was evaluated from coregistered images: MRI1-MRI2 and MRI1-MRI3. Dose volume histogram parameters from the treatment plan based on MRI1 were related to parameters based on needle positions in MRI2 or MRI3. Regression was used to model the average needle migration per implant and change in D90 clinical target volume, CTVprostate+3mm. The model fit was used for estimating the dosimetric impact in equivalent dose in 2 Gy fractions for dose levels of 6, 8.5, 10, 15, and 19 Gy. Needle migration was on average 2.2 ± 1.8 mm SD from MRI1-MRI2 and 5.0 ± 3.0 mm SD from MRI1-MRI3. D90 CTVprostate+3mm was robust toward average needle migration ≤3 mm, whereas for migration >3 mm D90 decreased by 4.5% per mm. A 3 mm of needle migration resulted in a decrease of 0.9, 1.7, 2.3, 4.8, and 7.6 equivalent dose in 2 Gy fractions for dose levels of 6, 8.5, 10, 15, and 19 Gy, respectively. Substantial needle migration in high-dose-rate brachytherapy occurs frequently in 1-3 hours following needle insertion. A 3-mm threshold of needle migration is proposed, but 2 mm may be considered for dose levels ≥15 Gy. Copyright © 2017 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

  13. Recent accumulation rates of an alpine glacier derived from firn cores and repeated helicopter-borne GPR

    Full Text Available The spatial representation of accumulation measurements is a major limitation for current glacier mass balance monitoring approaches. Here, we present a new method for estimating annual accumulation rates on a temperate alpine glacier based on the interpretation of internal reflection horizons (IRH in helicopter-borne ground-penetrating radar (GPR data. For each individual GPR measurement, the signal traveltime is combined with a simple model for firn densification and refreezing of meltwater. The model is calibrated at locations where GPR profiles intersect in two subsequent years and the densification can be tracked over time. Two 10.5 m long firn cores provide a reference for the density and chronology of firn layers. Thereby, IRH correspond to density maxima, but not exclusively to former summer glacier surfaces. From GPR profiles across the accumulation area, we obtain spatial distributions of water equivalent for at least four annual firn layers, reaching a mean density of 0.74 g cm−3. Refreezing accounts for 9% of the density increase over time and depth. The strongest limitation to our method is the dependence on layer chronology assumptions. The uncertainties inherent to the modelling approach itself are in the same order of conventional point measurements in snow pits. We show that GPR can be used to complement existing mass balance monitoring programs on temperate alpine glaciers, but also to retrospectively extend newly initiated time series.

    Cesarean section is an essential maternal healthcare service. Its role in labor and delivery care in low- and middle-income countries is complex; in many low-resource settings it is underutilized in the most needy of populations and overused by the less needy, without clear methods to ensure that universal access is available. Additionally, even if universal access were available, it is not evident that these countries would have the capacity or the finances to appropriate meet demand for the procedure, or that patients would want to utilize the care. This review summarizes the literature and illustrates the complicated relationship that cesarean section, which is rapidly on the rise around the world, has with individuals, communities, and nations in sub-Saharan Africa.

    carbetocin, a potentially cardio toxic drug is used by intravenous bolus for uterine bleeding prevention during cesarean section. The aim was to assess the cardiac effects of carbetocin in patients undergoing cesarean sections. a pretest-postest design study was carried out on 74 women (23 ± 5.3 years, ASA I-II classification, no history of pregnant induced-hypertension) who underwent elective or emergency cesarean section. At surgical room entry (baseline), and after administration of carbetocin (infunded 100 μg along 30 minutes) during the anesthesic-surgical follow up, vital signs and EKG were registered; and CK, CK MB, and troponin I blood levels were measured. Wilcoxon's rank test was used. significant changes were found on CK (30 vs. 58), CK MB (4.0 vs. 5.9), troponin I (0.01 vs. 0.03), blood sistolic pressure (110 vs. 100), blood diastolic pressure (70 vs. 60) and heart rate (76 vs. 90); all of them: p < 0.001. However, no patient showed heart ischemia signs during EKG monitoring. an increase on biochemical indicators of myocardiac damage blood levels was observed after the administration of a carbetocin bolus in patients underwent cesarean section.

    Full Text Available Objective: Satisfaction and postoperative care of women who undergo cesarean section is an important aspect and demand due attention. Hunger and thirst are frequently encountered after cesarean delivery. These increase distressing symptom and unsatisfaction. The aim of this paper was to detect the effect of early post cesarean feeding on mothers' satisfaction.Materials and methods: This study was a controlled trial. The research population was women delivering by cesarean section in Ommolbanin hospital, Mashhad, Iran. The samples consist of 82 women randomly assigned in two groups of study and control. The study group started oral fluids 4 hours after surgery, followed by regular diet after return of bowel sounds. The control group started oral fluids 12 hours after surgery and solid food was allowed after defecation. The groups were compared about satisfaction rate before discharge with VAS scale. Data were analyzed using chi-square, Fisher exact test, Kruskal walis test, t test and Mann Whitney.Results: The mean of women's satisfaction was 96.2 in early feed group and 56.7 in the control group. There was a statistically significant difference between two groups (p=0.000.Conclusion: this study showed that early feeding increases women's satisfaction. It is a safe, easy and enforceable intervention that can be usual in surgical units.

    To assess how enhanced postdischarge telephone follow-up calls would improve case finding for surgical site infection (SSI) surveillance after cesarean section. We conducted a prospective cohort study of all patients who delivered by cesarean section between April 22 and August 22, 2010. In addition to our routine surveillance, using clinical databases and electronic patient records, we also made follow-up calls to the patients at 7, 14, and 30 days postoperation. A standard questionnaire with questions about symptoms of SSI, health-seeking behaviors, and treatment received was administered. Descriptive statistics and univariate analysis were performed to assess the effect of the enhanced surveillance. One hundred ninety-three patients underwent cesarean section during this study period. Standard surveillance identified 14 infections with telephone follow-ups identifying an additional 5 infections. Using the call as a gold standard, the sensitivity of the standard methodology to capture SSI was 73.3%. The duration of the calls ranged from 1 to 5 minutes and were well received by the patients. Results suggest that follow-up telephone calls to patients following cesarean section identifies 26.3% of the total SSIs. Enhanced surveillance can provide more informed data to enhance performance and avoid underestimation of rates.

    Failure in complete healing of the wound is one of the probable complications of cesarean. The present study aimed to determine the effectiveness of dressing with aloe vera gel in healing of cesarean wound. This prospective randomized double-blind clinical trial was conducted on 90 women who had undergone cesarean operation in Amir-al-Momenin hospital (Gerash, Iran). The participants were randomly divided into two groups each containing 45 patients. In one group, the wound was dressed with aloe vera gel, while simple dressing was used in the control group. Wound healing was assessed 24 hours and 8 days after the cesarean operation using REEDA scale. The data were analyzed through Chi-square and t-test. The participants' mean age was 27.56±4.20 in the aloe vera group and 26.62±4.88 in the control group, but the difference was not statistically significant. However, a significant difference was found between the two groups concerning body mass index, heart rate, and systolic blood pressure (Paloe vera group and 35 ones in the control group had obtained a zero score 24 hours after the operation. These measures were respectively obtained as 42 and 41eight days after the operation. According to the findings of this study, the women are recommended to be informed regarding the positive effects of dressing with aloe vera gel.

  2. Should Cesarean Scar Defect Be Treated Laparoscopically? A Case Report and Review of the Literature.

    2015-01-01

    Several obstetric complications due to inappropriately healed cesarean scar such as placenta accreta, scar dehiscence, and ectopic scar pregnancy are increasingly reported along with rising cesarean rates. Furthermore, many gynecologic conditions, including abnormal uterine bleeding, pelvic pain and infertility, are imputed to deficient cesarean scar healing. Hysteroscopy is the most commonly reported approach for the revision of cesarean scar defects (CSDs). Nevertheless, existing evidence is inadequate to conclude that either hysteroscopy or laparoscopy is effective or superior to each other. Although several management options have been suggested recently, the laparoscopic approach has not been thoroughly scrutinized. We present a case and reviewed the data related to the laparoscopic repair of CSDs and compared the hysteroscopic and laparoscopic management options based on the data from previously published articles. As a result of our analyses, the laparoscopic approach increases uterine wall thickness when compared with the hysteroscopic approach, and both surgical techniques seem to be effective for the resolution of gynecologic symptoms. Hysteroscopic treatment most likely corrects the scar defect but does not strengthen the uterine wall; thus, the potential risk of dehiscence or rupture in subsequent pregnancies does not seem to be improved. Because large uterine defects are known risk factors for scar dehiscence, the repair of the defect to reinforce the myometrial endurance seems to be an appropriate method of treatment.

    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

    In the last decades has been a worldwide trend to increase the number of cesarean sections as an alternative of obstetric resolution, phenomenon for which it was proposed a variety of explanation, this fact remains practically unknown in the institutions of the National Health System (NHS) in Mexico. To identify the trend of the pregnancy to end for cesarean sections during the years of 1991-1995 in the 32 states of de country, as well as of all the institutions of the National Health System. Descriptive, cross sectional and retrospective. We use the data of the Bureau of Statistics and Informatics of de Health Ministry of each one of the 32 states of the country, of the years 1991 to 1995, and of the number of cesarean sections made in the hospitals of the different institutions of the NHS. We started off with a data-base, to calculate frequency tables, and the specific rate of the cesarean section for each year, for each one of the states and institutions of the NHS. We calculate the secular trends using the annual rates of cesarean section, for each one of the states and institutions of the NHS. We also made bivariate analysis and estimated the odds ratio (OR) and 95% Confidence Interval (95% IC); and the statistic X2 for trend, setting the two tailed statistic significance level of 0.05. During the study period, there was 7,503,817 births in all hospitals of the NHS, of these births 1,929,865 (25.72%) was resolved by cesarean section. For the whole period it there was a clear trend to increment of the cesarean section, the rate for 1991 was 20.44%, and by 1995 was 28.58%, the raise for the period was 39.82%, with values of the OR for trend of 1.56; 95% IC (1.55-1.57).

    Although venous thromboembolism (VTE) is the leading cause of maternal mortality in developed countries, the usefulness of preventive low-molecular weight heparin (LMWH) after cesarean section remains a matter of controversy. This article will review a recent decision analysis addressing this question, comparing a 7-day LMWH with none in this setting. Prophylaxis with LMWH yielded the highest quality-adjusted life expectancy, with a net gain of 1.5 days per treated patient. Sensitivity analyses showed the incidence of VTE after cesarean section and the haemorrhagic risk related to LMWH to be critical, at threshold values of 0.22% and 0.24% respectively. In the hypothetical cases created by the authors, LMWH was safe but only marginally more effective in women with no risk factors. With the addition of other risk factors, reductions in VTE greatly outnumbered the increase in major hemorrhages. This study highlights the need to assess the individual thrombotic risk in women after a cesarean section.

    Full Text Available OBJECTIVE: We examined the extent to which differences in hospital-level cesarean delivery rates in Massachusetts were attributable to hospital-level, rather than maternal, characteristics. METHODS: Birth certificate and maternal in-patient hospital discharge records for 2004-06 in Massachusetts were linked. The study population was nulliparous, term, singleton, and vertex births (NTSV (n = 80,371 in 49 hospitals. Covariates included mother's age, race/ethnicity, education, infant birth weight, gestational age, labor induction (yes/no, hospital shift at time of birth, and preexisting health conditions. We estimated multilevel logistic regression models to assess the likelihood of a cesarean delivery. RESULTS: Overall, among women with NTSV births, 26.5% births were cesarean, with a range of 14% to 38.3% across hospitals. In unadjusted models, the between-hospital variance was 0.103 (SE 0.022; adjusting for demographic, socioeconomic and preexisting medical conditions did not reduce any hospital-level variation 0.108 (SE 0.023. CONCLUSION: Even after adjusting for both socio-demographic and clinical factors, the chance of a cesarean delivery for NTSV pregnancies varied according to hospital, suggesting the importance of hospital practices and culture in determining a hospital's cesarean rate.

    Agenesis of the lung is a rare developmental defect characterized by complete absence of one lung, or hypoplasia of one or both lungs. The majority of reported cases have been associated with other congenital anomalies. It is usually detected in childhood as a result of either pulmonary symptoms or associated anomalies. Although pulmonary agenesis has been reported in adults, there is no report of the management of a pregnant patient for cesarean section in the anesthetic literature. We report the management of a 23-year-old pregnant female at 36 weeks' gestation with oligohydramnios and left lung agenesis for elective cesarean section. She presented with a history of repeated chest infection and was found to have restrictive lung function. She had no other congenital anomalies. Combined spinal epidural anesthesia was administered for cesarean section. The intraoperative course was uneventful except for bradyarrhythmias followed by tachyarrhythmias on manipulation of the uterus. She was given low dose epidural morphine with local anesthetic and intramuscular diclofenac for postoperative analgesia. We believe that normal pregnancy can safely be undertaken in the presence of left lung agenesis. In view of associated congenital anomalies in more than 50% of the cases, anesthetic management should include a particularly careful survey of other systems. The patient should otherwise be managed like any patient with limited pulmonary reserve. Combined spinal epidural anesthesia is safe and appropriate for such patients.

    Clark, Brian T.; Rustagi, Tarun; Laine, Loren

    2015-01-01

    OBJECTIVES Current guidelines recommend early repeat colonoscopy when bowel preparation quality is inadequate, defined as inability to detect polyps > 5 mm, but no data link specific bowel preparation categories or scores to this definition. Nevertheless, most physicians use a shortened screening/surveillance interval in patients with intermediate-quality preparation. We determined whether different levels of bowel preparation quality are associated with differences in adenoma detection rates (ADRs: proportion of colonoscopies with ≥1 adenoma) to help guide decisions regarding early repeat colonoscopy—with primary focus on intermediate-quality preparation. METHODS MEDLINE and Embase were searched for studies with adenoma or polyp detection rate stratified by bowel preparation quality. Preparation quality definitions were standardized on the basis of Aronchick definitions (excellent/good/fair/poor/insufficient), and primary analyses of ADR trichotomized bowel preparation quality: high quality (excellent/good), intermediate quality (fair), and low quality (poor/insufficient). Dichotomized analyses of adequate (excellent/good/fair) vs. inadequate (poor/insufficient) were also performed. RESULTS Eleven studies met the inclusion criteria. The primary analysis, ADR with intermediate- vs. high-quality preparation, showed an odds ratio (OR) of 0.94 (0.80–1.10) and absolute risk difference of −1% (−3%, 2%). ADRs were significantly higher with both intermediate-quality and high-quality preparation vs. low-quality preparation: OR = 1.39 (1.08–1.79) and 1.41 (1.21–1.64), with absolute risk increases of 5% for both. ADR and advanced ADR were significantly higher with adequate vs. inadequate preparation: OR = 1.30 (1.19–1.42) and 1.30 (1.02–1.67). Studies did not report other relevant outcomes such as total adenomas per colonoscopy. CONCLUSIONS ADR is not significantly different with intermediate-quality vs. high-quality bowel preparation.

    Full Text Available Prevalence of HIV infection in Ukraine is 1.6% overall, with antenatal prevalence of 0.52%, the highest in Europe. According to national protocol, cesarean section has been recommended for women with viral load above 50 copies/mL to further prevent vertical transmission of HIV. The aim of our study was to compare the infectious complication rates after cesarean delivery in HIV-infected women with advanced WHO stages of HIV disease who received HAART, and HIV-infected women with I or II WHO stages. Materials and methods: A retrospective analysis was performed on data derived from 150 HIV-infected women with advanced WHO stages of HIV disease (group I and 150 HIV-infected women with I or II WHO stages (group II, who underwent cesarean delivery. Postoperative infectious morbidity in both groups was analyzed according to whether the cesarean section was an elective or emergent delivery. Descriptive, comparison analyses were performed. Results: There was no significant difference between the both groups in terms of gravidity, parity, number of previous cesarean sections, estimated gestational age at time of delivery. It has been shown that HIV-infected women from the group I have 2 times more factors for the appearance of postpartum infectious complications, such as anemia, the urinary tract infection, sexually transmitted infections. Both groups of women were statistically more likely to experience postpartum endometritis when being delivered by emergent cesarean section than by elective cesarean section (14.6% versus 4.6%, respectively in the group I and 5.3% versus 0.5%, respectively, in the group II, superficial or deep wound breakdown (22.6% versus 4.6%, respectively, in the first group and 5.3% versus 2.6%, respectively, in the second group. Septic pelvic thrombophlebitis was only in 2% of HIV-infected women from the group I. Urinary tract infection had 25% HIV-infected women in the both groups. Overall, the rate of postpartum infectious

    Background: Spinal hyperbaric ropivacaine may produce more predictable and reliable anesthesia than plain ropivacaine for cesarean section. The dose-response relation for spinal hyperbaric ropivacaine is undetermined. This double-blind,randomized, dose-response study determined the ED50 (50% effective dose) and ED95 (95% effective dose) of spinal hyperbaric ropivacaine for cesarean section anesthesia. Methods: Sixty parturients undergoing elective cesarean section delivery with use of combined spinal-epidural anesthesia were enrolled in this study. An epidural catheter was placed at the L1~L2 vertebral interspace,then lumbar puncture was performed at the L3~L4 vertebral interspace, and parturients were randomized to receive spinal hyperbaric ropivacaine in doses of 10.5 mg, 12 mg, 13.5 mg, or 15 mg in equal volumes of 3 ml. Sensory levels (pinprick) were assessed every 2.5 min until a T7 level was achieved and motor changes were assessed by modified Bromage Score. A dose was considered effective ifan upper sensory level to pin prick ofT7 or above was achieved and no intraoperative epidural supplement was required. ED50 and ED95 were determined with use of a logistic regression model. Results: ED50 (95% confidence interval)of spinal hyperbaric ropivacaine was determined to be 10.37 (5.23~11.59) mg and ED95 (95% confidence interval) to be 15.39(13.81~23.59) mg. The maximum sensory block levels and the duration of motor block and the rate ofhypotension, but not onset of anesthesia, were significantly related to the ropivacaine dose. Conclusion: The ED50 and ED95 of spinal hyperbaric ropivacaine for cesarean delivery under the conditions of this study were 10.37 mg and 15.39 mg, respectively. Ropivacaine is suitable for spinal anesthesia in cesarean delivery.

    A decision-to-delivery interval (DDI) of no more than 20 minutes has long been considered a requirement for cesarean sections, even though there have hardly been any studies on this topic. We retrospectively investigated data relevant to DDI for emergency cesarean sections performed for the most common indications, namely, suspected and documented fetal asphyxia. We analyzed data on emergency in-hospital cesarean sections in the period 2008-2015. Low 5- and 10-minute Apgar scores (a scheme with points awarded for breathing, heart rate, muscle tone, skin coloration, and the elicitability of reflexes) were the primary endpoints; acid-base status in arterial cord blood and in-hospital neonatal death were the secondary endpoints. The raw analysis was supplemented by an analysis adjusted for various factors including gestational age, maternal age, and obstetrical presentation. Data from 39 291 neonates were included. The DDI was up to 10 minutes in 64.6% of cases, from 11 to 20 minutes in 34.3%, and over 20 minutes in 1.1%. Low Apgar scores were less common in children whose emergency cesarean sections were performed within 10 minutes or within 20 minutes. For example, the adjusted odds ratio for a 10-minute Apgar score below 4 was 0.49 (95% confidence interval [0.25; 0.96] when a DDI of more than 20 minutes was used as the reference criterion. This is the largest population-based, risk-adjusted analysis to be carried out on this topic to date. It reveals, for the first time, an association between DDI of 20 minutes or less and the avoidance of outcomes that are dangerous to the child. As it is not possible to predict such obstetrical emergencies in advance, it seems reasonable to ensure the availability of caredelivery structures that make it possible for emergency cesarean sections to be performed within 20 minutes of the decision to do so.

    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

    Full Text Available Background: Cesarean section is one of the common surgeries of women. Acute post-operative pain is one of the recognized post-operative complications. Aims: This study was planned to compare the effects of suppositories, indomethacin, diclofenac and acetaminophen, on post-operative pain and opioid usage after cesarean section. Materials and Methods: In this double-blind clinical trial study, 120 candidates of cesarean with spinal anesthesia and American Society of Anesthesiologists (ASA I-II were randomly divided into four groups. Acetaminophen, indomethacin, diclofenac, and placebo suppositories were used in groups, respectively, after operation and the dosage was repeated every 6 h and pain score and opioid usage were compared 24 h after the surgery. The severity of pain was recorded on the basis of Visual Analog Scale (VAS and if severe pain (VAS > 5 was observed, 0.5 mg/kg intramuscular pethidine had been used. Statistical Analysis Used: The data were analyzed in SPSS software version 15 and analytical statistics such as ANOVA, Chi-square, and Tukey′s honestly significant difference (HSD post-hoc. Results : Pain score was significantly higher in control group than other groups, and also pain score in acetaminophen group was higher than indomethacin and diclofenac. The three intervention groups received the first dose of pethidine far more than control group and the distance for diclofenac and indomethacin were significantly longer (P < 0.001. The use of indomethacin, diclofenac, and acetaminophen significantly reduces the amount of pethidine usage in 24 h after the surgery relation to control group. Conclusions : Considering the significant decreasing pain score and opioid usage especially in indomethacin and diclofenac groups rather than control group, it is suggested using of indomethacin and diclofenac suppositories for post-cesarean section analgesia.

    Illustrate laparoscopic technique for resection of cesarean scar ectopic pregnancy, associated with isthmocele repair. Case report SETTING: Tertiary referral centre in Strasbourg, France. The study was approved by the local IRB. Cesarean scar pregnancy is a rare form of ectopic pregnancy. The major risk of this type of pregnancy is the early uterine rupture with massive bleeding and maternal life-threatening. It is therefore crucial to manage actively these pregnancies as soon as they are diagnosed. Therapeutic options can be medical, surgical, or a combination of both. Many case reports or case series are found in the literature, but only few clinical studies, too difficult to carry out because of cases rarity and inconclusiveness. "Systematic review: What is the best first-line approach for cesarean section ectopic pregnancy?" is a meta-analysis that was published in 2016, and includes 194 studies between 1978 and 2014 (126 case reports, 45 cases series and 23 clinical studies). According to this systematic review, hysteroscopy or laparoscopic hysterotomy seems to be the best first-line approach to treat cesarean scar ectopic pregnancy. Uterine artery embolization seems to be reserved for significant bleeding and/or a high suspicion index for arteriovenous malformation. There is however no consensus on treatment of reference. The case concerns a 38-year-old primiparous women with cesarean section in 2010, who was diagnosed by US scan at 7 WG as cesarean scar ectopic pregnancy, confirmed by pelvic MRI. The patient has initially received medical treatment with two intramuscular injections of Methotrexate and one local intra-gestational injection of KCl. Initial rate of HCG was 82000 IU/L. Through a rigorous weekly biological and US scan monitoring, it has been observed an involution of the ectopic pregnancy at ultrasonography associated to HCG decreasing. No bleeding or infectious complications occurred during this period. After 10 weeks of monitoring, because of a

    Full Text Available OBJECTIVES: To compare uterine rupture, maternal and perinatal morbidity rates in women with one single previous cesarean after spontaneous onset of labor or low-dose prostaglandin-induced cervical ripening for unfavourable cervix. STUDY DESIGN: This was a retrospective cohort study of 4,137 women with one single previous cesarean over a 22-year period. Inpatient prostaglandin administration consisted in single daily local applications. RESULTS: Vaginal delivery was planned for 3,544 (85.7% patients, 2,704 (76.3% of whom delivered vaginally (vaginal birth after Cesarean (VBAC rate = 65.4%. Among women receiving prostaglandins (n=515, 323 (62.7% delivered vaginally. Uterine rupture (0.7% compared with 0.8%, OR 1.1, 95% CI 0.4-3.4, p=0.88, maternal (0.9% compared with 1.2%, OR 1.3, 95% CI 0.5-3.2, p=0.63 and perinatal (0.3% compared with 0.8%, OR 2.4, 95% CI 0.7-8.5, p=0.18 morbidity rates did not differ significantly between patients with spontaneous onset of labor and those receiving prostaglandins, nor did these rates differ according to the planned mode of delivery. CONCLUSION: In comparison with patients with spontaneous labor, inducing cervical ripening with low-dose prostaglandins in case of unfavourable cervix is not associated with appreciable increase in uterine rupture, maternal or perinatal morbidity.

    Rates of cesarean section increase worldwide, and the components of this increase are partially unknown. A strong role is prescribed to dystocia, and at the same time, the diagnosis of dystocia is highly subjective. Previous studies indicated that risk of cesarean is higher when women are admitted to the hospital early in the labor. We examined data on 1,202 nulliparous women with singleton, vertex pregnancies and spontaneous labor onset. We selected three groups based on cervical dilatation at admission: early (0.5-1.5 cm, N = 178), intermediate (2.5-3.5 cm, N = 320), and late (4.5-5.5 cm, N = 175). The Kaplan-Meier estimator was used to analyze the risk of delivery by cesarean section at a given dilatation, and thin-plate spline regression with a binary outcome (R library gam) to assess the form of the associations between the cesarean section in either the first or second stage versus vaginal delivery and dilatation at admission. Women who were admitted to labor early had a higher risk of delivery by cesarean section (18 versus 4% in the late admission group), while the risk of instrumental delivery did not differ (24 versus 24%). Before 4 cm dilatation, the earlier a woman was admitted to labor, the higher was her risk of delivery by cesarean section. After 4 cm dilatation, however, the relationship disappeared. These patterns were true for both first and second stage cesarean deliveries. Oxytocin use was associated with a higher risk of cesarean section only in the middle group (2.5-3.5 cm dilatation at admission). Early admission to labor was associated with a significantly higher risk of delivery by cesarean section during the first and second stages. Differential effects of oxytocin augmentation depending on dilation at admission may suggest that admission at the early stage of labor is an indicator rather than a risk factor itself, but admission at the intermediate stage (2.5-3.5 cm) becomes a risk factor itself.

Methods: Retrospectively determine the changes in the rate and indications of Caesarean sections in the past fourteen years in our hospital. Results: Between 1992 and 1996, the rate of Caesarean sections was relatively stable, averaging 26.013%. It rose above 30% in 1997, and increased to 57.12% in 2002. Post 2004, "societal factors" were controlled, and the incidence decreased to 54.71%, and to 49.74% in 2006. Conclusion:"Societal factors" and "over diagnosis" are im-portant contributors to the rise in the rate of Caesarean sections. Reinforcing "pregnancy education" and our understanding of their indications are key for reducing the rate of Caesarean sections.

    Cesarean section in buffaloes is an emergency operative procedure being performed prinicipally for uncorrectable uterine torsions and for delivery of fetal monsters. Left paramedian (lateral and parallel to the milk vein) and oblique ventrolateral (above arcus cruralis) are the two common operative sites used for buffalo caesarean section. Although many anesthetic combinations including intravenous and inhalation anesthetic procedures have been experimented in the buffalo species yet most caesarean sections in buffaloes are satisfactorily performed in right lateral recumbency under mild sedation and local infiltration analgesia or paravertebral nerve blocks. The history, indications, anesthesia, operative procedures, post operative complications and future fertility following caesarean section in buffalo are described.

    Objective: Any operation leads to body stress and tissue injury that causes pain and its complications. Glucocorticoids such as Dexamethasone are strong anti-inflammatory agents, which can be used for a short time post-operative pain control in various surgeries. Main purpose of this study is to evaluate the effect of administration of intravenous (IV) Dexamethasone on reducing the pain after cesarean. Methods: A double-blind prospective randomized clinical trial was performed on 60 patients candidate for elective caesarean section. Patients were randomly assigned into two groups: A (treatment: 8 mg IV Dexamethasone) and B (control: 2 mL normal saline). In both groups, variables such as mean arterial blood pressure (MAP), heart rate (HR), respiratory rate (RR), pain and vomiting severity (based on visual analog scale) were recorded in different time points during first 24 h after operation. Statistical methods using repeated measure analysis of variances and t-test, Mann-Whitney and Chi-square tests were used for analyzing data. Findings: The results indicated that within-group comparisons including severity of pain, MAP, RR and HR have significant differences (P < 0.001 for all variables) during the study period. Between group comparisons indicated significant differences in terms of pain severity (P < 0.001), MAP (P = 0.048) and HR (P = 0.078; marginally significant), which in case group were lower than the control group. Conclusion: IV Dexamethasone could efficiently reduce post-operative pain severity and the need for analgesic consumption and improve vital signs after cesarean section. PMID:24991614

    Objectives To assess, using individual level data, how the proportion of people in different employment statuses may have played a role in the prevalence of poor self-rated health from 1978 to 2004 as there have been major changes in employment patterns in advanced market democracies and employment is an important correlate of health. Design Individual-level analysis of repeated cross-sectional surveys. Setting UK. Participants 125 125 men and 139 535 women of working age (25–59). Outcome measure Self-rated general health. Results Compared to 1978 there was evidence of higher levels of poor health in the subsequent years. For example, in 2004, the prevalence of poor health was 2.8 (95% CI 1.7 to 3.9) and 1.3 (0.1 to 2.5) percentage points higher than 1978 for men and women, respectively, after adjusting for age. After additional adjustment for socio-economic characteristics, annual differences compared to 1978 increased (5.4 (4.2 to 6.5) and 4.4 (3.2 to 5.6) for men and women in 2004). Further adjustment for employment status, however, attenuated the annual differences in poor health (0.7 (−0.3 to 1.7) for men and 1.5 (0.3 to 2.6) for women in 2004). Conclusions These results suggest that the proportion of people in different employment statuses, particularly the proportion in sickness- or disability-related economic inactivity, could play an important role in the prevalence of poor self-rated health in the UK. Whether decreasing economic inactivity would enhance population health is an open question that needs further investigation. Trial registration This observational study was not registered.

    Recent laboratory shear-slip experiments conducted on a nominally flat frictional interface reported the intriguing details of a two-phase nucleation of stick-slip motion that precedes the dynamic rupture propagation. This behavior was subsequently reproduced by a physics-based model incorporating laboratory-derived rate-and-state friction laws. However, applying the laboratory and theoretical results to the nucleation of crustal earthquakes remains challenging due to poorly constrained physical and friction properties of fault zone rocks at seismogenic depths. Here we apply the same physics-based model to simulate the nucleation process of crustal earthquakes using unique data acquired during the San Andreas Fault Observatory at Depth (SAFOD) experiment and new and existing measurements of friction properties of SAFOD drill core samples. Using this well-constrained model, we predict what the nucleation phase will look like for magnitude ˜2 repeating earthquakes on segments of the San Andreas Fault at a 2.8 km depth. We find that despite up to 3 orders of magnitude difference in the physical and friction parameters and stress conditions, the behavior of the modeled nucleation is qualitatively similar to that of laboratory earthquakes, with the nucleation consisting of two distinct phases. Our results further suggest that precursory slow slip associated with the earthquake nucleation phase may be observable in the hours before the occurrence of the magnitude ˜2 earthquakes by strain measurements close (a few hundred meters) to the hypocenter, in a position reached by the existing borehole.

    Full Text Available BACKGROUND: There is currently no validated method for antepartum prediction of the risk of failed vaginal birth after cesarean section and no information on the relationship between the risk of emergency cesarean delivery and the risk of uterine rupture. METHODS AND FINDINGS: We linked a national maternity hospital discharge database and a national registry of perinatal deaths. We studied 23,286 women with one prior cesarean delivery who attempted vaginal birth at or after 40-wk gestation. The population was randomly split into model development and validation groups. The factors associated with emergency cesarean section were maternal age (adjusted odds ratio [OR] = 1.22 per 5-y increase, 95% confidence interval [CI]: 1.16 to 1.28, maternal height (adjusted OR = 0.75 per 5-cm increase, 95% CI: 0.73 to 0.78, male fetus (adjusted OR = 1.18, 95% CI: 1.08 to 1.29, no previous vaginal birth (adjusted OR = 5.08, 95% CI: 4.52 to 5.72, prostaglandin induction of labor (adjusted OR = 1.42, 95% CI: 1.26 to 1.60, and birth at 41-wk (adjusted OR = 1.30, 95% CI: 1.18 to 1.42 or 42-wk (adjusted OR = 1.38, 95% CI: 1.17 to 1.62 gestation compared with 40-wk. In the validation group, 36% of the women had a low predicted risk of caesarean section ( 40%; 10.9% and 47.7% of these women, respectively, actually had deliveries by caesarean section. The predicted risk of caesarean section was also associated with the risk of all uterine rupture (OR for a 5% increase in predicted risk = 1.22, 95% CI: 1.14 to 1.31 and uterine rupture associated with perinatal death (OR for a 5% increase in predicted risk = 1.32, 95% CI: 1.02 to 1.73. The observed incidence of uterine rupture was 2.0 per 1,000 among women at low risk of cesarean section and 9.1 per 1,000 among those at high risk (relative risk = 4.5, 95% CI: 2.6 to 8.1. We present the model in a simple-to-use format. CONCLUSIONS: We present, to our knowledge, the first validated model for antepartum prediction of the

    An attempt was made to ripen the uterine cervix in 100 high-risk pregnancy patients (pregnancy between 34 to 41 weeks' gestation), with the use of intracervical instillations of 0.25 mg of prostaglandin E2 mixed with a tylose gel. The maturation process was repeated every 48 hours. Forty-nine patients were delivered of infants after the first maturation and 51 patients required between two and nine instillations. In patients requiring multiple instillations, the mean delay between the first procedure and delivery was 9 +/- 4 days (range, 2.4 to 16 days). Among the 59 nulliparous women, only 23 were delivered of infants after a single maturation and 36 required multiple maturations (p less than 0.02). When the group of patients who were delivered of infants after a single maturation process was compared with the group requiring multiple maturations, no difference could be seen with regard to age, term of pregnancy, or Bishop cervical score at the time of inclusion in the study. The myometrial activity and the onset labor induced by prostaglandin E2, were similar in both groups. Fetal heart rate decelerations occurred in 16.3% (8/49) of the patients with single maturations and in 17.6% (9/51) of the patients who required multiple maturations. The outcome of the pregnancy and the rate of cesarean sections (24% and 27%) were similar in both groups. No patients required cesarean sections because of failed induction of labor. Cervical ripening after repeated applications of 0.25 mg of prostaglandin E2 seems to be safe for the fetus, providing that the patient is closely supervised.

    The relationship between tachyphylaxis (measured as a decrease in the rate of regression of sensory levels of analgesia) during repeated epidural injections of lidocaine and both the distribution of lidocaine within the epidural space (as measured by spread of simultaneous injection of the tracer technetium-99m diethylenetriaminepentaacetate (99mTc-DTPA)) and elimination of lidocaine from the epidural space (as measured by serum concentrations of lidocaine) was investigated in 18 patients undergoing minor surgery during lumbar epidural analgesia. Twelve patients received four injections of 20 mL of 2% lidocaine at 2-hr intervals. Epidural distribution was assessed by injection of 99mTc-DTPA diluted in saline on the preoperative day and diluted in an equal volume of 2% lidocaine on the morning before surgery and again after the fourth injection of lidocaine 6 hr later. The distribution of 99mTc-DTPA in the epidural space was unchanged during the three measurements despite significant tachyphylaxis in both sensory analgesia and motor blockade (11 of 12 patients had sensory analgesia 2 hr after the first injection in contrast to only 3 of 12 patients during the third injection). In another six patients 20 mL of 2% lidocaine were injected three times at 2-hr intervals before surgery, with measurements of serum concentrations of lidocaine after the first and last injections. Despite tachyphylaxis (no patient had sensory analgesia 2 hr after the third injection), there was no difference in the rate of disappearance of lidocaine from the epidural space as assessed by plasma lidocaine concentration curves during the first and third injection (0.5 +/- 0.1 and 0.3 +/- 0.04 microgram.mL-1.min-1, respectively).

    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
