Introduction Material and Methods Results Conclusions Vaginal birth after cesarean delivery (VBAC) attempt is promoted to reduce cesarean‐related morbidity, but it carries a risk of uterine rupture, posing significant maternal and neonatal risks. This study evaluated uterine rupture incidence and risk factors in a high VBAC attempt population.This was a 16‐year retrospective multicenter case–control cohort study (2002–2018). Eleven French university hospitals participated. Women were included if they had a complete uterine rupture during a VBAC attempt. Two controls, defined as a VBAC attempt without uterine rupture, were randomly included for each case. We analyzed the risk factors of uterine rupture among the overall population and then among women who had labor induction and those who had spontaneous labor. Logistic regression was used to compute crude odds ratios (ORs) and 95% confidence intervals (CIs) for uterine rupture. Multivariable logistic regression was used to calculate adjusted ORs (aORs) and 95% CIs.Among 48 124 patients with a single prior cesarean section, 31668 (65.8%, 95% CI 65.3–66.2) had a VBAC attempt and 23 086 (72.9% 95% CI 72.4–73.4) had a successful vaginal delivery. The complete uterine rupture frequency was 0.63%. There were 199 cases of complete uterine rupture (0.63%, 95%CI 0.54–0.71) and 396 controls. Among the overall population, the odds of uterine rupture was inversely associated with prior vaginal delivery (adjusted odds ratio [aOR] 0.3, CI 95% 0.2–0.5) and positively with induction of labor (aOR 2.2, 95% CI 1.4–3.4). For women with spontaneous labor, the odds of uterine rupture was positively associated with a Bishop score<6 (aOR 1.8, 95%CI 1.0–3.0), arrest of cervical dilatation of at least 1 hr. (aOR, 1.8 95%CI 1.1–2.9) and oxytocin augmentation (aOR 2.2 95% CI 1.3–3.7). For women undergoing labor induction, no factors were significantly associated with uterine rupture.Uterine rupture frequency was low among women with high rates of VBAC attempt and successful vaginal delivery and was reduced with previous vaginal birth and increased with induction of labor, regardless of the method used. It was associated with any dystocia during spontaneous labor and suspected macrosomia in induced women, which should be managed with caution. [ABSTRACT FROM AUTHOR]

• Total thickness of uterine wall and myometrial thickness are reduced after caesarean section scar. • Proportion of fibrom in myometrial wall is increased after caesarean section scar. • Reduced thickness of uterine wall in scared uterus remains even long after caesarean section scar. In recent years, caesarean section (CS) rate has risen worldwide. Complications associated with CS scars have risen too, such as scar dehiscences and uterine ruptures. Uterine healing is a complex phenomenon still poorly understood. The aim of this study is to carry out a comparative histological analysis of healthy and scarred uterus. Women who underwent hysterectomy for benign pathology were included prospectively and divided into two groups: previous CS (group 1) versus control (group 2). Hysterectomy specimen were analyzed histologically and immunohistochemically. Sixty women were included: 30 women per group. In group 1, only 19 women could be analyzed. Median total thickness at the thinnest site of the scar is significantly thinner (4.34 mm; IQR [2.76–9.45]) than that of adjacent healthy isthmus (12.70 mm; IQR [10.45–14.95]) (p < 0.001). It is also thinner than in group 2 (13.45 mm; IQR [11.03–16.90]) (p < 0.001). Median myometrial thickness within the scar in group 1 was also thinner (1.14 mm; IQR [0.30–2.69]) than that of the adjacent healthy isthmus (8.90 mm; IQR [8.18–10.08]) (p < 0.001) and that in group 2 (10.00 mm; IQR [8.38–13.35]) (p < 0.001). There was a significant increase in fibrosis in the scar (55.01 %; IQR [35.71–63.46]) compared with adjacent tissue (17.41 %; IQR [15.08–24.78]) (p < 0.001) and with healthy uterus (33.91 %; IQR [18.93–46.53]) (p = 0.006). In uterus with previous CS scar, total thickness of the wall and thickness of the myometrium are reduced and proportion of fibrosis is significantly increased. This study shows that the thickness of the wall remains reduced in scarred uterus, even very long after CS. Further studies are currently in progress to understand its pathophysiology within the uterus using animal models. [ABSTRACT FROM AUTHOR]

• Predicting induvial chances of morbidity regarding mode of delivery lacks performance. • Current predictors for morbidity regarding birth after caesarean have poor predictive value. • Trial of labor vs elective repeat caesarean has a significantly higher risk of morbidity. After a previous caesarean section, morbidity in the subsequent delivery in general is considered to depend on the probability of a vaginal birth after caesarean. However counselling could be improved by adding individualized probability of serious morbidity following either trial of labour or elective repeat caesarean section. The objective of this study was to develop prediction models for morbidity for both a repeat caesarean section and a trial of labor for a Dutch population. In this cohort study, data were joined from three previous studies (SIMPLE 1, SIMPLE 2 and SIMPLE 2-implementation study). A cohort of 2592 women with one previous caesarean section and a singleton pregnancy who delivered ≥37 weeks, without a contraindication for vaginal delivery was formed. Maternal morbidity was defined as postpartum hemorrhage, blood transfusion, uterine rupture, ICU admittance or death. Neonatal morbidity was defined as asphyxia, NICU-admittance or death. Potential predictors for morbidity were chosen based on literature and expert opinion. Logistic regression was used to develop the models. Internal validation was intended using bootstrapping techniques. Main outcome measures were predictors for morbidity and for validation of the model we used the area under the receiver operating characteristic curve for discriminative capacity and calibration for accuracy. In 324 out of the 2592 cases (12.7 %) maternal or fetal complications occurred. In general total morbidity was higher in women choosing TOL as compared to ERCS (p < 0.001). The performance of the several developed models was insufficient, the area under the receiver operating characteristic curve did not rise above 0.6. Due to poor model performance, before correction for overfitting, interval validation was not conducted. In this large cohort, developing a Dutch population based prediction model that aimed to improve counselling on the mode of delivery, by predicting individual chances of morbidity for different delivery modes was not possible, due to lack of performance. Further study could be directed to cut off on VBAC success rates to a more general advice regarding the safest mode of delivery. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to compare the outcomes of vaginal birth after cesarean (VBAC) with those of normal vaginal birth (NVB) in a tertiary hospital in China. Methods: This retrospective cohort study analyzed 1,024 women who birthed vaginally between January 2019 and December 2020. The VBAC group (n = 512) included women with one previous cesarean, while the NVB group (n = 512) had no previous caesareans. All women used epidural analgesia. We assessed maternal and neonatal complications using descriptive statistics, chi-square tests, and logistic regression. Statistical analysis was performed using SPSS version 25.0. Results: The VBAC group had an 87.5% success rate for vaginal birth under epidural analgesia, whereas the NVB group had a 100% success rate. A primary focus of the study was uterine rupture. Vaginal birth after cesarean was associated with a higher incidence of uterine rupture (0.8% vs 0%, p = 0.031), postpartum hemorrhage (6.6% vs 3.5%, p = 0.021) and the need for blood transfusions (2.7% vs 0.8%, p = 0.012) compared with NVB. There were no substantial differences in maternal infections, wound infections or perineal lacerations between the groups. Although neonatal outcomes were generally similar, the VBAC group experienced higher rates of 5-minute Apgar scores <7 (2.3% vs 0.6%, p = 0.009) and admissions to neonatal intensive care units (3.1% vs 1.2%, p = 0.016 Even after adjusting for confounders, VBAC remained an independent risk factor for several complications. Conclusion: Although VBAC is feasible and mostly safe, it is associated with a higher risk of specific complications compared with NVB. Careful selection of candidates and close monitoring are essential for optimizing outcomes in VBAC cases. [ABSTRACT FROM AUTHOR]

Objective: A cesarean delivery (CD) can affect health of both mother and child and future pregnancies. Since the abandonment of the one-child policy in China, obstetricians tend to perform a repeat CD rather than a trial of labor after cesarean (TOLAC). This study aims to reduce CD rates by increasing vaginal births after cesarean (VBAC) rates and introducing electrohysterography (EHG) for accurate monitoring. Methods: In total, 82 women received counseling regarding TOLAC at the Shijiazhuang Sixth Hospital in China. Women opting for TOLAC were randomized for either external tocodynamometry (TOCO, i.e. standard care) or EHG. The primary outcome was the VBAC rate. Secondary outcomes were indications for CD, percentage of assisted vaginal deliveries, labor duration, maternal blood loss, complications and neonatal outcomes. Results: After accounting for preterm delivery and dropouts, all counseled women opted for a TOLAC (100%). After randomization, 42 women were included in the TOCO-group and 37 in the EHG-group. Women did not receive pain medication and labor was not augmented with oxytocin. The VBAC rate was 71.4% in the TOCO-group, versus 78.4% in the EHG-group (p =.48). Birth was assisted with forceps in 11.9% of TOCO-group versus 2.7% of EHG-group (p =.21). One secondary CD (i.e. a shift from intended vaginal delivery to surgical delivery within the same labor) was performed because of a suspicion of uterine rupture (TOCO-group). Other indications for CD were: fetal distress, labor dystocia, fetal position, cephalopelvic disproportion. There were no significant differences in secondary study outcomes. No complications were reported. Conclusion: This study showed an average VBAC rate of 75%, without any complications, in a hospital with no previous experience with TOLAC. The VBAC rate with EHG-monitoring was higher than TOCO, although this difference was not significant. To demonstrate a significant difference, larger clinical studies are necessary. Trial registration: The Daily Board of the Medical Ethics Committee of The Maternal and Child Hospital of Shijiazhuang approved the study protocol (number 20171018, Dutch Trial Register NL8199).

Background: Twin pregnancy is associated with higher risks of adverse perinatal outcomes for both the mother and the babies. Among the many challenges in the follow-up of twin pregnancies, the mode of delivery is the last but not the least decision to be made, with the main influencing factors being amnionicity and fetal presentation. The aim of the study was to compare perinatal outcomes in two European centers using different protocols for twin birth in case of non-cephalic second twin; the Italian patients being delivered mainly by cesarean section with those in Belgium being routinely offered the choice of vaginal delivery (VD). Methods: This was a dual center international retrospective observational study. The population included 843 women with a twin pregnancy ≥ 32 weeks (dichorionic or monochorionic diamniotic pregnancies) and a known pregnancy outcome. The population was stratified according to chorionicity. Demographic and pregnancy data were reported per pregnancy, whereas neonatal outcomes were reported per fetus. We used multiple logistic regression models to adjust for possible confounding variables and to compute the adjusted odds ratio (adjOR) for each maternal or neonatal outcome. Results: The observed rate of cesarean delivery was significantly higher in the Italian cohort: 85% for dichorionic pregnancies and 94.4% for the monochorionic vs 45.2% and 54.4% respectively in the Belgian center (p-value < 0.001). We found that Belgian cohort showed significantly higher rates of NICU admission, respiratory distress at birth and Apgar score of < 7 after 5 min. Despite these differences, the composite severe adverse outcome was similar between the two groups. Conclusion: In this study, neither the presentation of the second twin nor the chorionicity affected maternal and severe neonatal outcomes, regardless of the mode of delivery in two tertiary care centers, but VD was associated to a poorer short-term neonatal outcome.

Objective: We examined whether the chest-to-head circumference ratio at birth was associated with breech presentation and transverse lie. We also described the obstetric management of such pregnancies in the Japan Environment and Children's Study (JECS). Methods: We performed a cross-sectional evaluation of data collected between January 2011 and March 2014 in a nationwide prospective birth cohort study, the JECS. We analyzed 83,822 non-anomalous singletons born at 34–41 weeks' gestation to mothers with no history of previous cesareans or uterine surgery. We defined low, normal (reference group), and high chest-to-head circumference ratios as <10th percentile, 10th to 90th percentiles, and >90th percentile, respectively. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for breech presentation and transverse lie. The timing and mode of delivery of such pregnancies were examined. Results: Breech presentation was recorded in 2.6% and transverse lie in 0.2%. A low chest-to-head circumference ratio was associated with increased rate of breech presentation (5.2%; adjusted OR 2.36, 95% CI: 2.10–2.65) and transverse lie (0.3%; adjusted OR 2.33, 95% CI: 1.50–3.60), whereas a high ratio was linked to reduced breech presentation (1.1%; adjusted OR 0.51, 95% CI: 0.39–0.66). Subgroup analysis of children delivered by cesarean (n = 7971) showed a similar association, albeit with slightly reduced strength for breech presentation. Eighty-three percent of breech births and 46.3% of transverse lie births occurred at 37–38 weeks' gestation. Cesarean section was performed in 96.8% of breech presentations and 63.4% of transverse-lie ones. Conclusions: These findings imply that the fetal chest-to-head circumference ratio may influence presentation at birth. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to estimate the median effective dose of intrathecal isobaric ropivacaine without opioid required for adequate cesarean delivery anesthesia after epidural labor analgesia. Methods: Patients aged 20–40 years with American Society of Anesthesiology scores of I–II, body mass index ≤ 36, who underwent emergency cesarean delivery after failed vaginal delivery with epidural analgesia of a duration ≤ 6 h were included in the study. After removal of the epidural used for labor analgesia, a new combined spinal epidural was performed, and a dose of intrathecal isobaric ropivacaine without opioid was administered. The dose was determined using up–down methodology, with the starting patient's dose set to 12 mg. Adequate anesthesia, defined as a pinprick level no lower than T6 at 5 min after ropivacaine administration, resulted in the next patient receiving a dose of ropivacaine 1 mg higher, and inadequate anesthesia 1 mg lower. The primary outcome was the median (95% confidence interval (CI)) dose of spinal ropivacaine required for adequate cesarean delivery anesthesia. Results: Of the 46 patients included in the study, 40 were analyzed. The median spinal ropivacaine dose was 8.11 mg (95% CI 7.29–8.93 mg) by the Dixon and Mood method and 8.06 mg (95% CI 6.93–9.00 mg) by isotonic regression. Two patients had high spinal anesthesia. Conclusion: Our findings suggest that for 50% of patients undergoing cesarean delivery after failed vaginal delivery with epidural analgesia, an 8-mg spinal dose of isobaric ropivacaine without opioid provides an anesthesia level no lower than T6 at 5 min.

Objective: To analyze the success rate of external cephalic version (ECV) in pregnant women with a history of previous cesarean section, as well as to describe the rate of complications associated with the procedure. Methods: A retrospective cohort study of women who were offered an ECV at "Virgen de la Arrixaca" Clinic University Hospital (Murcia, Spain) between January 2014 and December 2023. We collected data for previous cesarean delivery, obstetric history, fetal presentation, amniotic fluid volume, ECV success rate, complications related to ECV, mode of delivery, and neonatal outcomes. The study confidently performed ECV under sedation with propofol and tocolysis with ritodrine. Univariate and multivariate analyses were conducted to compare the success rate of ECV, ECV complications, and mode of delivery between women with and without previous cesarean sections. Results: Of 1116 pregnant women who were offered ECV, 911 were included in the study, with 42 having a previous cesarean section. The success rate of ECV in pregnant women with a previous cesarean section was 78.6% (adjusted odds ratio 1.18; 95% confidence interval 0.49–2.86; P = 0.708), with a low complication rate of 9.5%, such as non‐reassuring fetal heart rate (7.1%) or major vaginal bleeding (2.4%). Of the women who attempted a vaginal delivery after ECV, 80.8% were successful. Conclusions: These findings support that ECV is a safe and effective option for women with a previous cesarean section, with success rates comparable to those in women without a previous cesarean section. Synopsis: Success and complication rates of external cephalic version are similar in women with and women without a history of cesarean section. [ABSTRACT FROM AUTHOR]

Objectives: To assess the accuracy of ultrasound measurement of the lower uterine segment (LUS) thickness against findings at laparotomy, and to investigate its correlation with the success rate of vaginal birth after one previous caesarean delivery (CD) in a resource‐limited setting. Design: Prospective study. Setting: Obstetrics and Gynaecology department in a tertiary hospital in Ghana. Population: Women with one previous CD undergoing either a trial of labour (TOLAC) or elective CD. Methods: Myometrial lower uterine segment thickness (mLUS) and full lower uterine segment thickness (fLUS) were measured with transvaginal ultrasound (TVUS). The women were managed according to local protocols with the clinicians blinded to the ultrasound measurements. The LUS was measured intraoperatively for comparison with ultrasound measurements. Main outcome measures: Lower uterine segment findings at laparotomy, successful vaginal birth. Results: A total of 311 pregnant women with one previous CD were enrolled; 147 women underwent elective CD and 164 women underwent a TOLAC. Of the women that underwent TOLAC, 96 (58.5%) women had a successful vaginal birth. The mLUS was comparable to the intraoperative measurement in the elective CD group with LUS thickness <5 mm (bias of 0.01, 95% CI −0.10 to 0.12 mm) whereas fLUS overestimated LUS <5 mm (bias of 0.93, 95% CI 0.80–1.06 mm). Successful vaginal birth rate correlated with increasing mLUS values (odds ratio 1.30, 95% CI 1.03–1.64). Twelve cases of uterine defect were recorded. LUS measurement ≤2.0 mm was associated with an increased risk of uterine defects with a sensitivity of 91.7% (95% CI 61.5–99.8%) and specificity of 81.8% (95% CI 75.8–86.8%). Conclusion: Accurate TVUS measurement of the LUS is technically feasible in a resource‐limited setting. This approach could help in making safer decisions on mode of birth in limited‐resource settings. Linked article: This article is commented on by Oyelese pp. 1780–1781 in this issue.

The article discusses the controversy surrounding the fetal pillow, a medical device used during caesarean deliveries. The device's approval and clinical use were based on limited and questionable evidence, leading to concerns about its safety and efficacy. The article highlights the importance of rigorous evaluation of new medical devices, improved journal processes, and regulatory oversight to prevent similar incidents in the future. It concludes by emphasizing the need for clinicians to demand high-quality evidence before adopting new technologies and for publishers, regulators, and evidence synthesis groups to ensure the integrity of published research.

Introduction Material and Methods Results Conclusions Cesarean sections are increasing worldwide and are associated with altered risks of complications for both mother and child. Vaginal birth after cesarean section is associated with lower maternal and neonatal morbidity than in repeat cesarean section. Only a few studies have considered the indication for the previous cesarean section to be of importance for the outcome of subsequent labor. The aim of this study was to evaluate whether the indication for a previous cesarean section affects the outcomes at a subsequent delivery in women with induction of labor.This retrospective cohort study of the four largest delivery units in Stockholm during 2012–2015 included 1150 women with one previous cesarean section with induction of labor. Inclusion criteria: women with induced labor and a previous cesarean section, singleton pregnancy, cephalic presentation, gestational age of ≥34 weeks. The women were grouped by indication for the previous cesarean section. Primary outcome: mode of delivery (vaginal birth after previous cesarean section or repeat cesarean section). Secondary outcomes: induction to delivery time, postpartum hemorrhage, uterine rupture. Neonatal outcomes: birth weight, Apgar score <7, arterial umbilical cord blood gas pH <7.0.Our study found that the indication of labor dystocia at the previous cesarean section, increased the risk of repeat cesarean section (aOR 5.35; 95% CI: 1.64–17.50) in women with induction of labor. Other risk factors for repeat cesarean section were birth weight >4000 g, maternal BMI ≥30 or if vaginal prostaglandin was used as the method for induction of labor. A previous vaginal delivery and use of oxytocin increased the chance of a vaginal delivery in this group of women.Our study showed that the indication for the previous cesarean section affects the outcome in the subsequent delivery in women with induction of labor. If the indication for the previous cesarean section was labor dystocia, the risk of repeat cesarean section was increased. [ABSTRACT FROM AUTHOR]

Objective To investigate the prenatal diagnosis and perinatal outcomes between anterior placenta accreta and non-anterior placenta. Methods A retrospective analysis was done for 560 pregnant women who were diagnosed with placenta accreta and delivered in the Third Affiliated Hospital of Guangzhou Medical University .According to the location of the placenta, the group was dividing into anterior placenta accreta group (319 cases) and non-anterior placenta accreta group (241 cases). The general characteristics, maternal and infant outcomes of the two groups were analyzed. The non-anterior placenta accrete group (241 cases) then were dividing into two groups according to the time of clear diagnosis. Those who were firstly diagnosed with placenta accrete during or after the operation was the intrapartum diagnosis group (missed diagnosis) (70 cases), and those who were diagnosed with clear placenta accreta before the delivery was prenatal diagnosis group (171 cases). The general characteristics, maternal and infant outcomes of the two groups were also analyzed. Results There were statistically significant differences in the parity, history of cesarean section, delivery mode, degree of placenta accreta, missed diagnosis rate, neonatal birth weight, and hysterectomy rate between the non-anterior placenta accrete group and the anterior placenta accreta group. In the case of prenatal diagnosis of different degrees of placenta accreta, the prenatal diagnosis rate of placental adhesion in the non-anterior placenta accreta group was lower than that of the anterior placenta accreta group, which was statistically significant. In the non-anterior placenta accrete group, there were statistically significant differences in the age, cesarean section history, placenta previa status, mode of delivery, degree of implantation, 24-hour bleeding volume, blood transfusions, NICU transfer rate, uterine loss rate between the intrapartum diagnosis group (missed diagnosis) and the prenatal diagnosis group. Conclusions The high-risk factors of patients with non-anterior placenta accreta are different from those of patients with anterior placenta accreta. Multiple births and a history of cesarean section are high-risk factors for anterior placenta accreta patients. Non-anterior placenta accreta are more likely to be missed diagnosed, especially the placental adhesion. For pregnant women with non-anterior placenta accreta missed diagnosis, there is a high rate of adverse birth outcomes, especially in the rate of neonatal transfer to the NICU.

Background: Vaginal Birth after Cesarean Birth (VBAC) is a birth mode recommended for reducing repeat cesarean which potentially contributes to adverse outcomes. However, VBAC is not normally practiced in some countries. Providers are an important part of the decision-making process on modes of birth among pregnant individuals. Providers' perspective on VBAC can influence whether they support or avoid conducting VBAC. This review aimed to explore providers' perspective on VBAC. Methods: The comprehensive search was conducted from six databases including PubMed, MEDLINE, Scopus, Cochrane Library, EMBASE, and Google scholar. The studies published in English between 2013 and 2023 were review. The Medical Subject Heading terms for VBAC and perspective were used to search. The eligible studies were selected by the PRISMA flow chart. The initial search yielded 558 articles. After excluding duplicates, articles not retrieved for full-text, and not meeting inclusion and exclusion criteria, eight articles were recruited. Quality appraisal of the studies was performed by the tool of the Joanna Briggs Institute. The meta-aggregation approach was applied to synthesize the findings. Results: Eight qualitative articles were included in this review, and six themes were developed including (1) different recognition of VBAC, (2) differences of willingness level of conducting Trial of Labor after Cesarean (TOLAC) (the approach attempting to have VBAC), (3) skills and resources needed when performing TOLAC, (4) protocol for recruiting candidacy and TOLAC management, (5) final decision making on VBAC, and (6) onset and duration of providing TOLAC information. Conclusion: Providers play an important role in influencing individuals' decision on modes of birth. Providers' positive recognition and willingness of conducting TOLAC potentially impact successful VBAC rate. However, the lawsuit caused by adverse outcomes from TOLAC/VBAC is a main reason for choosing repeat cesarean. Trial registration: PROSPERO registration number of this systematic review: CRD42023427662. Plain english summary: Repeat cesarean is a primary contributor to high cesarean rates globally. Vaginal Birth after Cesarean Birth (VBAC) is a vaginal birth of individuals with previous cesarean. While some countries have high successful VBAC rates, many countries have very low VBAC rates and do not support a vaginal birth in subsequent pregnancy among individuals with previous cesarean. Healthcare providers especially obstetricians and nurse-midwives play an important role in individuals' decision on mode of birth, so do individuals with previous cesarean. Healthcare providers' perspective on modes of birth among individuals with previous cesarean is very essential to support or not support individuals to have VBAC. In high VBAC rate countries, healthcare providers think VBAC is an optimal option for individuals with previous cesarean and have high confidence to do VBAC. On the other hand, healthcare providers in low VBAC rate countries think VBAC can cause a catastrophic birth outcome as uterine dehiscence and they are scared of being sued from the adverse outcome. One approach to support VBAC, most healthcare providers suggest that individuals with previous cesarean should be educated about VBAC right after the first cesarean or first antenatal visit because VBAC is not a common mode of birth for individuals in some countries and they need time to make a decision on mode of birth for their subsequent pregnancy.

The article highlights the advantages and struggles of implementing a patient-care protocol of enhanced recovery after surgery (ERAS) among mother-baby nurses. Topics mentioned include the definition of buy-in, the common barriers to buy-in, the decrease in opioid consumption and length of stay in ERAS protocol and a description of ERAS protocol.

Cesarean section (CS) is a life‐saving procedure when performed for the right indication but carries substantial risks, specifically during subsequent pregnancies. The aim of this study was to evaluate obstetric outcomes for women 5 years after a CS performed by medical doctors and associate clinicians. This was a prospective multi‐center observational study of women who had a CS at any of nine hospitals in Sierra Leone. Women and their offspring were followed up with three home visits for 5 years after surgery. Outcomes of interest included long‐term complications, mode and place of delivery, and maternal and pediatric outcomes of subsequent pregnancies. Of the 1274 women included in the study, 140 (11.0%) were lost to follow‐up. Within 5 years after the index CS, 27.0% of the women became pregnant and 2.5% had a second pregnancy. Women with perinatal death at the index CS had 5.25 higher odds of becoming pregnant within 1 year. Of the 259 women who delivered, 31 (12.0%) had a planned CS and 228 (88.0%) attempted a trial of labor after CS, resulting in either a successful vaginal birth (n = 138; 60.5%) or an emergency CS (n = 90; 39.5%). Peripartum and long‐term complications did not significantly differ between those that were operated on by medical doctors and associate clinicians. Within 5 years after CS, one in four women became pregnant again and more than half had a vaginal delivery. Significant differences in place and mode of birth between wealth quintiles illustrate inequities. [ABSTRACT FROM AUTHOR]

Objective Following the release of A Randomized Trial of Induction versus Expectant Management (ARRIVE) trial, the induction of labor at 39 weeks has increased in the United States. The risk of uterine rupture and optimal timing of elective induction in those patients with a prior cesarean delivery is not well-described, and they were not included in the original trial. We aimed to determine the risk of uterine rupture in those patients undergoing elective induction of labor with prior cesarean delivery. Study Design This was a retrospective cohort of participants with prior cesarean delivery from 1996 to 2000. Participants were included if they had two or more prior cesareans. Participants were excluded if they had a history of an unknown prior incision, a classical incision, gestational age <39 weeks, any diabetes, chronic hypertension, twin gestation, collagen or vascular disease, or HIV. Those undergoing expectant management were compared with those undergoing elective induction with no medical or obstetrical indications for delivery. Analysis was performed at three gestational age groups: 39 weeks, 40 weeks, and 41 weeks. The primary outcomes were uterine rupture, rates of successful vaginal delivery, and a composite major morbidity risk. Multivariable logistic regression was performed. Results At 39 weeks, 618 (10.3%) elective inductions were compared with 5,365 (89.7%) undergoing expectant management; uterine rupture occurred more frequently (13 patients [2.1%] vs. 49 patients [0.9%]; adjusted odds ratio [aOR], 2.5; 95% confidence interval, 1.3–4.6) with fewer successful vaginal birth after cesarean [VBAC; 66.8 vs. 75%; aOR, 0.6; 95% confidence interval, 0.5–0.7]. The risk of uterine rupture was similar between groups at 40 weeks (5 patients [0.8%] vs. 21 patients [1.2%]; p = 0.387) and 41 weeks (7 patients [1.4%] vs. 2 patients (0.8%); p = 0.448). Conclusion Patients undergoing elective induction of labor with a prior cesarean scar had an increased risk of uterine rupture when compared with expectant management at 39 weeks, with fewer successful VBAC. Key Points TOLAC elective induction at 39 weeks has an increased risk of uterine rupture. TOLAC elective induction at 39 weeks has a less successful chance of vaginal delivery. Awaiting spontaneous labor in this cohort does not increase the risk of uterine rupture. [ABSTRACT FROM AUTHOR]

Objective: To investigate whether women undergoing their first vaginal delivery after a previous cesarean section (secundiparous) are at increased risk for obstetric anal sphincter injury (OASI) compared with primiparous women. Methods: A retrospective cohort study of 85 428 women who delivered vaginally over a 10‐year period in a single tertiary medical center. Incidence of OASI, risk factors, and clinical characteristics were compared between primiparous women who delivered vaginally and secundiparous women who underwent their first vaginal birth after cesarean section (VBAC). A multivariable logistic regression analysis was used to study the association between VBAC and OASI. Results: Overall, 36 250 primiparous and 1602 secundiparous women were enrolled, 309 of whom had OASI. The rates of OASI were similar among secundiparous women who had VBAC and primiparous women who underwent vaginal delivery (15 [0.94%] vs 294 [0.81%], P = 0.58). The proportions of third‐ and fourth‐degree tears were also similar among secundiparous and primiparous women who experienced OASI (87% vs 91.5%, and 13% vs 8.5%, respectively, P = 0.68). Furthermore, the rates of OASI were similar in both study groups, although secundiparous women who underwent VBAC had higher rates of birth weights exceeding 3500 g (414 [25.8%] vs 8284 [22.8%], P = 0.016), and higher rates of vacuum‐assisted deliveries (338 [21%] vs 6224 [17.2%], P < 0.001). A multivariate logistic regression analysis failed to establish a statistically significant association between VBAC and OASI (odds ratio 0.672, 95% confidence interval 0.281–1.61, P = 0.37). Conclusions: No increased risk for OASI was found in secundiparous women who underwent VBAC compared with primiparous women at their first vaginal birth. Synopsis: Vaginal birth after cesarean section was not found to be associated with an increased risk of obstetric anal sphincter injury. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to assess maternal and neonatal outcomes in patients with polyhydramnios attempting trial of labor after cesarean (TOLAC) compared to those undergoing planned repeat cesarean delivery (PRCD). Methods: A multi-center retrospective cohort study was conducted and included women with term singleton viable pregnancies following a single low-segment transverse cesarean delivery (CD) with a polyhydramnios diagnosis (maximal vertical pocket > 8 cm and/or Amniotic Fluid Index > 24 cm) within 14 days before birth who delivered between the years 2017 and 2021. Maternal and neonatal outcomes were compared between those attempting TOLAC and those opting for PRCD. The primary outcome was composite adverse maternal. Univariate analysis was followed by multivariate analysis to control for potential confounders. Results: Out of 358 included births with a previous CD, 208 (58.1%) attempted TOLAC, while 150 had PRCD (41.9%). The successful vaginal birth after cesarean (VBAC) rate was 82.2%, and no cases of uterine rupture, hysterectomy, or maternal intensive care unit admission occurred in either group. After controlling for potential confounders, no independent association between TOLAC and composite adverse maternal (adjusted odds ratio [aOR] 0.62, 95% confidence interval [CI] 0.32–1.20, p = 0.16) and neonatal (aOR 0.89, 95% CI 0.51–1.53, p = 0.67) adverse outcomes was demonstrated. Conclusion: In patients with a term diagnosed polyhydramnios, TOLAC appears to be a reasonable alternative associated with favorable outcomes. Larger prospective studies are needed to refine management strategies and enhance maternal and neonatal outcomes in this context. [ABSTRACT FROM AUTHOR]

Objective This study aimed to compare adverse neonatal outcomes associated with the trial of labor after cesarean (TOLAC) at term in pregnancies according to maternal prepregnancy body mass index (BMI; kg/m 2) and the presence of previous vaginal delivery (VD). Study Design This was a repeated cross-sectional analysis of individuals with singleton, cephalic, and term deliveries with a history of one or two cesarean deliveries in the Linked Birth/Infant Death data from 2011 to 2020. Outcomes were examined according to the BMI category including BMI <30, 30 to 39.9, and 40 to 69.9 kg/m 2. The primary outcome was a composite neonatal outcome, defined as any presence of neonatal death, neonatal intensive care unit admission, assisted ventilation, surfactant therapy, or seizures. Outcomes were compared between TOLAC and elective repeat cesarean delivery (eRCD) after stratifying by BMI category and previous VD. Log-binomial regression was performed to obtain adjusted relative risk (aRR) with 99% confidence intervals, controlling for covariates. Results Of 4,055,440 individuals, 2,627,131 had BMI <30 kg/m 2 , 1,108,278 had BMI 30 to 39.9 kg/m 2 , and 320,031 had BMI 40 to 69.9 kg/m 2. In individuals with no previous VD, VD rates after TOLAC were 66.7, 57.2, and 48.1%, respectively. In individuals with previous VD, VD rates after TOLAC were 81.4, 74.7, and 67.3%, respectively. In individuals without previous VD, compared with those who had an eRCD, those who had TOLAC were more likely to experience composite neonatal outcomes in individuals with BMI < 30 kg/m 2 (5.0 vs. 6.5%; aRR = 1.33 [1.30–1.36]), BMI 30 to 39.9 kg/m 2 (6.1 vs. 7.8%; aRR = 1.29 [1.24–1.34]), and BMI 40 to 69.9 kg/m 2 (8.2 vs. 9.0%; aRR = 1.15 [1.07–1.23]). In individuals with previous VD, there was no difference in the composite neonatal outcomes in BMI < 30 kg/m 2 (6.2 vs. 5.8%; aRR = 0.98 [0.96–1.00]), BMI 30 to 39.9 kg/m 2 (7.4 vs. 7.1%; aRR = 0.99 [0.95–1.02]), and BMI 40 to 69.9 kg/m 2 (9.4 vs. 8.7%; aRR = 0.96 [0.91–1.02]). Conclusion TOLAC among obese individuals could be offered in selected cases. Key Points TOLAC among obese individuals could be offered selectively, despite their reduced likelihood of attempting or succeeding at it. Higher BMI individuals show decreased rates of both attempting and achieving successful TOLAC. Despite these trends, attempting TOLAC after a previous vaginal delivery does not heighten neonatal complications. [ABSTRACT FROM AUTHOR]

This article discusses the rising maternal mortality rate in the United States and the potential role of family medicine in addressing this issue. It highlights the disparities in maternal mortality rates, particularly for Black women, and emphasizes the need for alternative maternity care models. The article compares the roles of family medicine physicians, OB/GYNs, and midwives in providing obstetric care and presents evidence that family medicine obstetric care can lead to positive outcomes. It also discusses the reasons why family physicians are abandoning obstetrics and suggests potential solutions. The article concludes by emphasizing the importance of collaboration between family medicine and other healthcare providers and the need for mutual respect and appreciation. The Moms2B program and integrating more FMOBs into FQHCs are highlighted as successful strategies to improve prenatal and pediatric care and decrease adverse outcomes. The article also emphasizes the importance of including African American family physicians in these efforts to improve health outcomes for Black individuals. [Extracted from the article]

ObjectiveTo describe patient approaches to navigating their probability of a vaginal birth after cesarean (VBAC) within the context of prediction scores generated from the original Maternal-Fetal Medicine Units' VBAC calculator, which incorporated race and ethnicity as one of six risk factors.MethodsWe invited a diverse group of participants with a history of prior cesarean delivery to participate in interviews and have their prenatal visits recorded. Using an open-ended iterative interview guide, we queried and observed these individuals' mode-of-birth decisions in the context of their VBAC calculator scores. We used a critical and feminist approach to analyze thematic data gleaned from interview and visit transcripts.ResultsAmong the 31 participants who enrolled, their self-identified racial and ethnic categories included: Asian or South Asian (2); Black (4); Hispanic (12); Indigenous (1); White (8); and mixed-Black, -Hispanic, or -Asian background (4). Predicted VBAC success probabilities ranged from 12% to 95%. Participants completed 64 interviews, and 14 prenatal visits were recorded. We identified four themes that demonstrated a range of patient-led approaches to interpreting the probability generated by the VBAC calculator: 1) rejecting the role of race and ethnicity; 2) reframing failure, finding success; 3) factoring the physical experience of labor; and 4) modifying the probability for VBAC.ConclusionOur findings demonstrate that a numeric probability for VBAC may not be highly valued or important to all patients, especially those who have strong intentions for VBAC. Black and Hispanic participants challenged the VBAC calculator's incorporation of race and ethnicity as a risk factor and resisted the implication it produced, especially that their bodies were less capable of achieving a vaginal birth. Our findings suggest that patient-led approaches to assessing and interpreting VBAC probability may be an untapped resource for achieving a more person-centered, equitable approach to counseling.

Background & aim: Trial of labor after cesarean (TOLAC) to achieve vaginal delivery is considered acceptable in women with one previous cesarean. This study was performed to compare the success rate and maternal and neonatal outcomes of TOLAC after one and two previous cesarean sections.Methods: This cross-sectional study was conducted in September 2018 and March2020 by convenience sampling on 339 pregnant women with a history of one or two previous cesarean sections in Mashhad. TOLAC was performed for all eligible participants, if cesarean section performed due to any reason, it was considered a failed TOLAC. Maternal and neonatal outcomes by a check list were recorded during TOLAC and one week later. Data were analyzed by SPSS (version 24). Results: TOLAC was successful in 301 cases (94.1%), but 19 (5.9%) underwent cesarean section. Maternal age, parity, and frequency of comorbidities were significantly higher in those with two previous cesarean sections compared to those with one previous cesarean section (P0.05). Conclusion: Considering standard precautions in patient selection, TOLAC has a high enough success rate to justify recommending it to the selected women with one or two previous cesarean section.

Background: Most German hospitals do not offer a trial of labour after two caesarean sections (TOLA2C). TOLA2C is claimed to be associated with too many complications, above all the high risk of uterine rupture. The objective of this study is to review our experience with TOLA2C, with special attention paid to the risk and probability of uterine ruptures. Secondary outcomes include comparing neonatal and maternal outcomes in the group of TOLA2C with the group of elective repeat caesarean section (ERCS) and to assess the success rate for vaginal birth after two caesarean sections (VBAC-2). Methods: The retrospective cohort study was conducted in a community hospital in North Rhine-Westphalia. Inclusion criteria were all pregnant women with two caesarean sections in their medical history, with a current vertex singleton pregnancy and the absence of morphological abnormalities of the foetus, who gave birth in our facility between January 2015 and June 2021. Descriptive statistics were calculated and Kolmogorov-Smirnov tests, Mann-Whitney U tests, Fishers exact tests, Chi2 –tests and t-tests for independent samples were performed. Results: A total of 91 cases were included in the TOLA2C-group. These were compared to 99 cases that, within the same time frame, had an elective repeat caesarean section (ERCS-group). There was no statistically significant difference found in the neonatal outcome between the two groups (except for the neonatal pH-value: p 0.024). The hospital stay was significantly shorter in the TOLA2C-group, while maternal complication rates were almost similar (13.2% in the TOLA2C-Group, vs. 16.2% in the ERCS-Group). The success rate for TOLA2C was 55%. No complete uterine rupture was found, but in three cases an incomplete rupture (3.3% rate for incomplete uterine ruptures) occurred, but had no influence on the neonatal outcome. Conclusion: TOLA2C is not associated with a worse maternal or neonatal outcome compared to ERCS, and especially the risk of complete uterine ruptures seems to be low. TOLA2C should be more widely offered to suitable patients who are motivated for it. [ABSTRACT FROM AUTHOR]

To evaluate differences in reproductive and neonatal outcomes on the basis of the time interval from cesarean delivery to subsequent frozen embryo transfer (FET). Retrospective cohort. Multicenter fertility practice. Women undergoing autologous elective single embryo transfer FET after prior cesarean delivery. Time from prior cesarean delivery to subsequent FET. live birth (LB). A total of 6,556 autologous elective single embryo transfer FET cycles were included. Frozen embryo transfer cycles were divided into eight groups on the basis of the time interval from prior cesarean delivery to subsequent FET in months. A secondary analysis was then performed with time as a continuous variable. The proportion of LBs did not differ significantly across all time interval groups and over continuous time (range: 40.0%–45.6%). The mean gestational age at the time of delivery did not significantly differ as the time between prior cesarean delivery and subsequent FET increased (range: 37.3–38.4). When time was evaluated continuously, the proportion of preterm births was higher with a shorter time between cesarean delivery and subsequent FET. The mean birth weight ranged from 3,181–3,470g, with a statistically significant increase over time. However, the proportions of extremely low birth weight, very low birth weight, and low birth weight did not significantly differ. There were no significant differences in reproductive outcomes on the basis of the time interval from cesarean delivery to FET, including LB. The proportion of preterm deliveries decreased with a longer time between cesarean delivery and FET. Differences in mean neonatal birth weight were not clinically significant because the proportion of low birth weight neonates was not significantly different over time. Although large, this sample cannot address all outcomes associated with short interpregnancy intervals, particularly rarer outcomes such as uterine rupture. When counseling patients, the timing of FET after cesarean delivery must be balanced against the risks of increasing maternal age on reproductive and neonatal outcomes. [ABSTRACT FROM AUTHOR]

Background: Rates of cesarean birth (CBs) are steadily increasing and account for 36.7% of all births in New South Wales (NSW), with primary cesareans driving the increase. NSW Health guidelines recommend women attempt a vaginal birth after a previous CB (VBAC); however, rates of VBAC are decreasing, particularly within the private hospital setting. This study aimed to determine the rates of adverse outcomes for women who planned a VBAC (pVBAC) compared with women who planned an elective repeat CB (pERCB) at one private hospital in Sydney, Australia. Method: This retrospective data review evaluated patient records over a 10‐year period (2010–2019). Records (n = 2039) were divided into four groups: pVBAC, pVBAC + EMCB, labor + ERCB (lab + ERCB), and pERCB. The incidence of adverse maternal and neonatal outcomes is reported as counts and percentages. Regression and chi‐squared tests were used to compare groups. Significance was determined at a p‐value of <0.05. Results: Overall, very low rates (N = 148, 7.3%) of women had a VBAC compared with a repeat CB at this private hospital over the 10‐year period. The incidence of adverse outcomes was low regardless of study group. Outcomes differed significantly between groups for postpartum hemorrhage (pERCB seven times less likely than VBAC group) and special care nursery admission (pVBAC + EMCB is 4.6 times more likely than in the VBAC group). Conclusion: Overall, it is safe to attempt a VBAC at this private hospital, and labor after a cesarean should be recommended, yet very few women had a VBAC at the study site. The incidence of adverse outcomes was low compared with other published research. [ABSTRACT FROM AUTHOR]

Trial of Labor After Cesarean (TOLAC) is the process of attempting a vaginal delivery after a prior cesarean section. TOLAC offers an alternative to repeat cesarean delivery but requires careful assessment of risks and benefits. This research aims to evaluate the factors affecting VBAC success and associated risks, providing guidance for clinical practice in determining VBAC eligibility. Relevant literature on VBAC was sourced from databases such as PubMed and Cochrane Library using the keywords "VBAC," "VBAC success," and "VBAC risks." Literature searches for these articles are conducted through databases of scientific journals such as PubMed and Google Scholar. Analysis was conducted to assess predictive factors for VBAC success, including previous vaginal delivery history, cervical conditions, and other parameters. VBAC success is significantly influenced by previous vaginal delivery history, cervical conditions at admission, and factors such as BMI and interpregnancy interval. The main risk associated with VBAC is uterine rupture, occurring in approximately 0.2-0.9% of cases. Proper management and careful risk assessment can minimize complications. VBAC can be a safe and effective option for women who meet specific criteria. Adequate monitoring and assessment are crucial to minimize risks and enhance success rates. Individual evaluation and thorough planning are essential for achieving optimal delivery outcomes. The decision to implement VBAC should be made with careful consideration of the benefits and risks to ensure safe and optimal outcomes for both mother and baby. [ABSTRACT FROM AUTHOR]

Background: Cesarean section (C-section) rates are increasing globally, and repeated C-sections are associated with increased maternal morbidity. Trial of labor after C-section (TOLAC) is an approach to reduce the recurrence of C-sections. However, limited research exists on the impact of cesarean scars on labor duration in TOLAC, considering the termination of labor through C-section and selection bias. This study aimed to investigate the impact of cesarean scars on labor duration in TOLAC participants, accounting for potential confounding factors and biases. Methods: This retrospective cohort study included 2,964 women who attempted vaginal birth at a single center in Japan from 2012 to 2021. The study categorized participants into TOLAC (n = 187) and non-TOLAC (n = 2,777) groups. Propensity scores were calculated based on 14 factors that could influence labor duration, and inverse probability of treatment weighting (IPTW) was applied. Cox proportional hazards regression analysis estimated hazard ratios (HRs) for labor duration, with and without IPTW adjustment. Sensitivity analyses used propensity score matching, bootstrapping, and interval censoring to address potential biases, including recall bias in the reported onset of labor. Results: The unadjusted HR for labor duration in the TOLAC group compared to the non-TOLAC group was 0.83 (95% CI: 0.70–0.98, P = 0.027), indicating a longer labor duration in the TOLAC group. After adjusting for confounding factors using IPTW, the HR was 0.98 (95% CI: 0.74–1.30, P = 0.91), suggesting no significant difference in labor duration between the groups. Sensitivity analyses using propensity score matching, bootstrapping, and interval censoring yielded consistent results. These findings suggested that the apparent association between TOLAC and longer labor duration was because of confounding factors rather than TOLAC itself. Conclusions: After adjusting for confounding factors and addressing potential biases, cesarean scars had a limited impact on labor duration in TOLAC participants. Maternal and fetal characteristics may have a more substantial influence on labor duration. [ABSTRACT FROM AUTHOR]

Objective This article identifies how mode of delivery and the presence of labor affect the initiation and effectiveness of breastfeeding. Study Design This is a retrospective cohort study of breastfeeding success after vaginal delivery, cesarean section after labor, and scheduled cesarean section in term, singleton deliveries in nulliparous patients at a large academic institution from 2017 to 2018. Exclusion criteria included major postpartum complications requiring admission to the surgical intensive care unit or neonatal intensive care unit, general anesthesia, and major fetal anomalies. Breastfeeding success in the immediate postpartum period, defined as the first 2 to 3 days postpartum prior to hospital discharge, was measured by the presence of breastfeeding, the need for formula supplementation, the average number of breastfeeding sessions per day, the average amount of time spent at each breastfeeding session, the average number of newborn stools and wet diapers produced daily, and the neonatal percentage in weight loss over the first 2 to 3 days of life. Multivariable linear and logistic regression were used to assess the association between mode of delivery and markers of breastfeeding success after adjusting for potential confounders. A Tukey's post hoc analysis with pairwise comparisons was performed to assess differences in breastfeeding outcomes between vaginal delivery, scheduled cesarean section, and cesarean section after labor. Results A total of 2,966 women met inclusion criteria during the study period, 1,936 (65.3%) of whom underwent spontaneous vaginal delivery, 415 (14.0%) of whom delivered by scheduled cesarean section, and 615 (20.7%) of whom underwent cesarean section after labor. There were significant differences in maternal age, obesity, race/ethnicity, insurance status, gestational age at delivery, birth weight, and 1-minute Apgar's score less than 7 between vaginal delivery, scheduled cesarean section, and cesarean section after labor. There were also significant differences between indication for oxytocin, type of anesthesia, and postpartum hemorrhage between the three groups. After controlling for these factors, women who underwent vaginal delivery were more likely to have infants with decreased need for formula supplementation (adjusted odds ratio [aOR] = 1.71, 95% confidence interval [CI]: 1.52–1.93) and were less likely to switch from breast to formula feeding (aOR = 1.71, 95% CI: 1.04–1.31) in comparison to women who delivered via cesarean section in labor or scheduled cesarean section. The infants of these women also had an increased number of breastfeeding sessions on average (β = 0.06, p = 0.002), required fewer number of daily formula feedings (β = 0.14, p < 0.001), and experienced a smaller percentage in neonatal weight loss over the first 2 to 3 days of life (β = 0.18, p < 0.001) compared to those born after cesarean section and cesarean section after labor. These women comparatively required less time at each breastfeeding session (β = 0.06, p = 0.005), and produced fewer wet diapers and stools on average (β = 0.12, p < 0.001 and β = 0.12, p < 0.001, respectively). On post hoc analysis with pairwise comparisons, and on separate sensitivity analysis of only women who underwent cesarean delivery, there was no difference in breastfeeding outcome measures between scheduled cesarean section and cesarean section in labor. Conclusion Women who deliver by cesarean section, despite the presence or absence of labor, are less likely to maintain exclusive breastfeeding postpartum and are more likely to require formula supplementation. These women may need more support with breastfeeding after surgery in order to experience similar benefits for neonatal growth and weight gain. Key Points Women who deliver by cesarean section are less likely to maintain exclusive breastfeeding. Women who deliver by cesarean section are more likely to require formula supplementation. Women may need more support with breastfeeding after cesarean delivery. [ABSTRACT FROM AUTHOR]

Objective: This study aims to assess the fetal outcome in terms of early neonatal mortality among women undergoing emergency caesarean section for fetal distress. Methods: It is a Descriptive cross-sectional study involving 167 patients who were diagnosed with fetal distress and underwent emergency c-sections. The study was conducted at the Department of Obstetrics & Gynecology Unit-II, Holy Family Hospital, Rawalpindi from 24-09-2018 to 24-03-2019. Frequencies of fetal death were evaluated. Effect modifiers were controlled by the stratification. A P-value of = 0.05 was considered as significant. Results: The mean maternal age of the study population was found to be 24.59±3.20 years while the mean gestational age was recorded as 38.88±1.40 weeks. Fetal death was observed in 6.6% (n=11) of the total study population. A statistically significant difference was present among APGAR score, gestational age and fetal weight. However, statistically no significant difference was observed among maternal age, maternal height and maternal weight. Conclusions: The frequency of fetal death following emergency caesarean section for fetal distress was found to be 6.6% (n=11). A statistically significant difference (P=0.05) was present among APGAR score, gestational age and fetal weight for fetal outcome in our study. [ABSTRACT FROM AUTHOR]

Background: The rising global Cesarean section (CS) rate has increased interest in vaginal birth after Cesarean (VBAC) due to its benefits over elective repeated CS. Aim: This study aimed to evaluate the use of trans-abdominal ultrasound (TAUS) in assessing lower uterine segment (LUS) thickness in females with previous CS, highlighting its predictive value and potential clinical decision-making role. Methods: We conducted a thorough search on Google Scholar, PubMed, Embase, & Cochrane Library. The investigation utilized both textual terms and medical subject titles, such as TAUS, CS, LUS and trial of labour (TOL) across Medline, Embase, ClinicalTrials.gov and Cochrane Library. In addition, we conducted a thorough search on ClinicalTrials.gov and examined the references cited in selected publications and reviews to discover more relevant observational research. Results: Regarding elective repeat CS, TAUS measurements correlated with delivery outcomes and LUS thickness, with cut-off values varying from 1.5 to 4.05 millimeters. The pooled analysis exhibited a relative risk (RR) of 0.7 (95% confidence interval: 0.4, 0.9), with high heterogeneity (Chi-p <0.001, I² = 100%). Concerning uterine dehiscence & rupture, an association was found between thin LUS and uterine dehiscence (7 studies) and uterine rupture (1 study). An RR of 0.09 (95% confidence interval: 0.04, 0.15) for dehiscence and 0.003 (95% confidence interval: -0.001, 0.006) for rupture. Major heterogeneity for dehiscence (Chi-p <0.001, I² = 100%) and homogeneity for rupture (Chi-p <0.9, I² = 0%). Conclusion: TAUS is a valuable non-invasive tool for assessing LUS thickness in females with previous CS, thereby influencing clinical decisions. [ABSTRACT FROM AUTHOR]

Background: The rising global rates of cesarean sections (CS) and pregnancies with CS history necessitate the assessment of uterine scar integrity, potentially using transabdominal or transvaginal ultrasounds as a predictive tool. Aim: To compare the accuracy and utility of transabdominal and transvaginal ultrasound in measuring lower uterine segment (LUS) thickness at term. Materials and Methods: We conducted a thorough search on Google Scholar, PubMed, Embase, and Cochrane Library. The investigation utilized both text terms and medical subject headings, such as LUS Thickness, (CS), Transabdominal Ultrasound (TAS), Transvaginal Ultrasound (TVS), Scar Dehiscence, Rupture of uterus, Vaginal Birth following Cesarean, Vaginal Birth After Cesarean (VBAC). Also, we conducted a thorough investigation on ClinicalTrials.gov and examined the references cited in selected materials and reviews to discover any more pertinent observational research. Results: This meta-analysis incorporated data from 9 studies involving 1,789 patients to assess the differences in lower uterine segment (LUS) thickness measured by (TAS) and (TVS). The studies included participants aged eighteen to 44 years, with a BMI range of 20.7 to 50.4 kilogram/metrer² and gestational ages from 36 to 40 weeks. Our combined analysis revealed a statistically significant variance in LUS thickness between the groups (Z = 4.42, P < 0.0001), highlighting the potential of ultrasound measurement techniques in predicting uterine scar complications. Conclusion: The findings support the clinical use of LUS measurement, particularly via transvaginal sonography (TVS), as valuable tool in guiding delivery decisions, especially for those considering a trial of labor after cesarean (TOLAC).

Objective: This study aimed to evaluate whether a trial of labor after cesarean delivery (TOLAC) in women with a bicornuate uterus is associated with increased maternal and neonatal morbidity compared to women with a non-malformed uterus. Methods: A multicenter retrospective cohort study was conducted at two university-affiliated centers between 2005 and 2021. Parturients with a bicornuate uterus who attempted TOLAC following a single low-segment transverse cesarean delivery (CD) were included and compared to those with a non-malformed uterus. Failed TOLAC rates and the rate of adverse maternal and neonatal outcomes were compared using both univariate and multivariate analyses. Results: Among 20,844 eligible births following CD, 125 (0.6%) were identified as having a bicornuate uterus. The overall successful vaginal delivery rate following CD in the bicornuate uterus group was 77.4%. Failed TOLAC rates were significantly higher in the bicornuate group (22.4% vs. 10.5%, p < 0.01). Uterine rupture rates did not differ between the groups, but rates of placental abruption and retained placenta were significantly higher among parturients with a bicornuate uterus (9.8% vs. 4.4%, p < 0.01, and 9.8% vs. 4.4%, p < 0.01, respectively). Neonatal outcomes following TOLAC were less favorable in the bicornuate group, particularly in terms of neonatal intensive care unit admission and neonatal sepsis. Multivariate analysis revealed an independent association between the bicornuate uterus and failed TOLAC. Conclusions: This study found that parturients with a bicornuate uterus who attempted TOLAC have a relatively high overall rate of vaginal birth after cesarean (VBAC). However, their chances of achieving VBAC are significantly lower compared to those with a non-malformed uterus. Obstetricians should be aware of these findings when providing consultation to patients. [ABSTRACT FROM AUTHOR]

Objective: To determine the possible association between acute fetal stress during labor and maternal blood levels of osteopontin (OPN), white blood cells, sedimentation, and C-reactive protein (CRP). Methods: The study included women with a term pregnancy (37 weeks or more) who had a cesarean section during the active phase of labor. The study included 30 term pregnancies who underwent cesarean section for fetal distress and 30 pregnant women who underwent cesarean section for other indications (prior uterine surgery, head-pelvis incompatibility, large baby, non-progressing plot) as a control group. The levels of OPN and other inflammatory markers (leukocytes, sedimentation, CRP) in the maternal venous blood of 60 pregnant women were compared, and whether there was a significant association between the groups was investigated. Results: OPN levels in the fetal stress group were higher than those in the control group, and the difference was statistically significant (p=0.008). There was no statistically significant difference in white blood cell, blood sedimentation, and CRP levels between the two groups (p>0.005). Conclusion: Placental inflammation plays a role in the etiology of fetal stress, and OPN may be released because of fetal stress. The increase in OPN in maternal blood during labor may be an important marker for predicting fetal stress. [ABSTRACT FROM AUTHOR]

This article's emphasis is on the holistic care of women who are assessed as suitable for and amenable to vaginal birth after Caesarean section (VBAC) in the South African state health sector context. It is beyond its scope to deal with the minutiae of VBAC conduct, operative conduct of repeat Caesarean section (CS), or management of uterine rupture. It is also beyond the scope of the article to reflect on practices, which are accepted in other healthcare contexts. The intention is not to promote VBAC over elective repeat CS, but rather to assist healthcare workers with providing high-quality holistic care. The goal is that women with previous CS are given access to the mode of delivery, which is safest for them and their fetus, while minimising adverse psychological effects of previous and future negative birth experiences.

Background: Uterine rupture is a rare, but dangerous obstetric complication that can occur during trial of vaginal birth. Methods: The aim of this study was to evaluate the relationship between peripartum infection at the first caesarean delivery to uterine dehiscence or rupture at the subsequent delivery. We conducted a retrospective case-control study from March 2014 to October 2020 at a single academic medical center. The study group included women with a prior caesarean delivery and proven dehiscence or uterine rupture diagnosed during their subsequent delivery. The control group included women who went through a successful vaginal birth after cesarean section (VBAC) without evidence of dehiscence or uterine rupture. We compared the rate of peripartum infection during the first cesarean delivery (CD) and other relevant variables, between the two groups. Results: A total of 168 women were included, 71 with uterine rupture or dehiscence and 97 with successful VBAC as the control group. The rate of peripartum infection at the first caesarean delivery was significantly higher in the study group compared to the control group (22.2% vs. 8.2%, p = 0.013). Multivariate logistic regression analysis found that peripartum infection remained an independent risk factor for uterine rupture at the subsequent trial of labor after CD (95% confidence interval, p = 0.034). Conclusion: Peripartum infection in the first caesarean delivery, may be an independent risk-factor for uterine rupture in a subsequent delivery. [ABSTRACT FROM AUTHOR]

Background Vaginal birth after caesarean section (VBAC) is an alternative to a caesarean section (CS) in the absence of repeat or new indications for primary CS. There is a knowledge gap regarding the trend and successful VBAC in Ethiopia. Therefore this systematic review and meta-analysis aimed to assess the trend, pooled prevalence of successful VBAC and its predictors in Ethiopia. Methods Electronic databases (SCOPUS, CINAHL, Embase, PubMed and Web of Science), Google Scholar and lists of references were used to search works of literature in Ethiopia. Stata version 14 was used for analysis and the odds ratios of the outcome variable were determined using the random effects model. Heterogeneity among the studies was assessed by computing values for I2 and p-values. Also, sensitivity analyses and funnel plots were done to assess the stability of pooled values to outliers and publication bias, respectively. Results A total of 12 studies with a sample size of 2080 were included in this study. The overall success rate of VBAC was 52% (95% confidence interval 42 to 65). Cervical dilatation ≥4 cm at admission, having a prior successful vaginal delivery and VBAC were the predictors of successful VBAC. Conclusions Meta-analyses and sensitivity analyses showed the stability of the pooled odds ratios and the funnel plots did not show publication bias. The pooled prevalence of successful VBAC was relatively low compared with existing evidence. However, the rate was increasing over the last 3 decades, which implies it needs more strengthening and focus to decrease maternal morbidity and mortality by CS complications. Promoting VBAC by emphasizing factors favourable for its success during counselling mothers who previously delivered by CS to enhance the prevalence of VBAC. [ABSTRACT FROM AUTHOR]

• Women undergoing trial of labour following two previous caesareans (TOLA2C) are more likely to develop endometritis or sepsis postnatally. • Women undergoing TOLA2C are more likely to have a longer postnatal stay. • Neonates of women undergoing TOLA2C are more likely to have Apgar scores less than seven and require neonatal unit admission. • The best predictor of successful vaginal delivery following TOLA2C is a prior successful vaginal birth after caesarean. To assess the (i) predictors of and associated rates of success and; (ii) maternal and perinatal outcomes of women undergoing trial of labour after two previous caesarean sections (TOLA2C). This retrospective cohort study collected data from two regional obstetric centres with 12,000 deliveries per annum collectively. The population included singleton pregnancies undergoing (i) TOLA2C, (ii) elective repeat caesarean section following two caesarean sections (ERCS) and (iii) trial of labour after one caesarean section (TOLA1C). Data was collected electronically from 2013 to 2021. Statistical analysis included Fisher exact and Kruskal-Wallis test to compare unpaired samples alongside univariate and multivariable logistic regression. The primary outcome measure was maternal and perinatal outcome. The three groups included; n = 146 TOLA2C, n = 206 ERCS and n = 99 TOLA1C. TOLA2C had a success rate of 65 % compared to 74 % for TOLA1C (p = 0.16). The optimal predictor of successful TOLA2C was previous successful TOLA1C OR 8.65 (95 % CI 2.75–38.41). TOLA2C was associated with greater risk of endometritis and/or sepsis postnatally compared to the other two groups [10.3 % (n = 15) versus 0.5 % (n = 1) and 3 % (n = 3) for ERCS and TOLA1C respectively p < 0.01]. It was also associated with longer maternal hospital stay [2.4 days (+/-1.8) versus 1.8 (+/-0.8) and 1.8 (+/-1.7) p < 0.01], a greater proportion of neonates with Apgar scores less than 7 (p =<0.01) and higher rates of neonatal unit admission [14 % (n = 20) versus 5 % (n = 11) versus 4 % (n = 4) (p =<0.01)]. Women considering trial of labour following two caesarean sections should be counselled regarding the potential increased risk of endometritis, sepsis and adverse neonatal outcome.

Background: Almost a third of all deliveries now involve a caesarean section (CS). Trial of labor after caesarean (TOLAC) followed by vaginal birth after caesarean (VBAC) is crucial for lowering the total caesarean rate since repeat caesarean is the most prevalent single rationale for caesarean. Aim: this study was conducted to assess the incidence, and maternal and neonatal outcomes of vaginal birth after caesarean section. Methods: This retrospective cohort study was conducted at the obstetrics and gynecology department in of Beni-Suef General Hospital. The data was obtained from the files of each patient. The collected data included reported history taking, clinical examinations, preoperative and postoperative investigations, details of previous deliveries, and maternal and fetal outcomes of vaginal delivery following caesarean section. The success rate of TOLAC was (84.9%) while the failure rate was (15.1%). Results: The rate of succeeded VBAC was (1.6%) while the rate of CS was (38%) from all deliveries in 2016 and 2017. There was a difference between succeeded VBAC group and failed group regarding the history of previous vaginal delivery, number, causes, type, indications of prior CS(s), duration between CS and current pregnancy, presentation, medical disorders, fetal heart rate (FHR), Apgar score and need for neonatal intensive care unit (NICU) admission. Conclusion: Regarding VBAC precautions, factors that improve success are previous lower segment CS, previous vaginal delivery, cephalic presentation, a single full-term fetus of average weight, good maternal health (free of medical disorder), the patient is in an active phase of the first stage of labor and previous vaginal delivery. VBAC became one of the solutions to avoid the complications of ERCD as there are fewer complications, shorter hospital stays, faster recovery, avoidance of major surgery, and reduced risk of NICU admission.

Background: The optimal management of breech presentation remains a debate among obstetricians worldwide. The Term Breech Trial (2000) highlighted elective caesarean section as a preferable method over vaginal delivery for breech presentations. This study investigates delivery modes in women who had an elective caesarean section for breech presentation in their first pregnancy. Objective was to evaluate delivery outcomes in the second pregnancy of women who had an elective caesarean section for breech presentation in their first pregnancy. Methods: A cross-sectional study was conducted at Jinnah International Hospital Abbottabad from October 10, 2018, to April 10, 2019. Data was collected from 321 women who had an elective caesarean section for breech presentation during their first pregnancy. The study used per-abdominal examination and obstetrical ultrasound to assess foetal presentation and recorded the mode of delivery in the second pregnancy. Results: Participants' ages ranged from 18 to 49 years, with a mean age of 28.87±4.07 years. The average interval between deliveries was 1.92±0.92 years, labour duration averaged 5.56±2.41 hours, and foetal head engagement averaged 2.92±1.35. Of the participants, 18.7% achieved a vaginal delivery, while 81.3% had a repeat caesarean section. Reasons for repeat caesarean included recurrent breech presentation in 44.9% and foetal distress in 32.4%. Conclusion: Approximately 18.7% of women who had an elective caesarean section for breech presentation in their first pregnancy achieved vaginal delivery in their second pregnancy, whereas the majority underwent another elective caesarean section [ABSTRACT FROM AUTHOR]

Background: Cesarean section (CS) is among the most common obstetric operations globally, and recent research shows a rise in the prevalence of CS. Maternal morbidity and mortality related to CS is a major public health concern across the world. This necessitates a study of the impact of recurrent CSs on mother morbidity. Patients and Methods: This Cross-sectional study was carried out on 165 women in the Department of Obstetrics and Gynecology, Zagazig University Hospitals by analyzing the data and records of all women who underwent multiple repeated CSs. The women were allocated according to the number of CSs into 3 groups, the maternal outcomes and complications as adhesions, hysterectomy, or blood transfusion requirements of all groups were examined retrospectively. Results: The current study included a total of 165 participants. Our results revealed that the most frequent complication was adhesion ~59.39%, followed by intraoperative hemorrhage and need for blood transfusion (19.4%), and the less frequent complication was endometritis and no maternal death. There was a significant difference between the groups regarding maternal age, BMI, hospital stay, and operative time, while no significance was found in pre/postoperative hemoglobin. Conclusions: Our results endorse our assumption that the risk of maternal complications increases as the number of CSs increases. There is no clear absolute threshold for the number of CSs, but a total of 4 or more cesarean deliveries was identified as the critical level for most of the major complications. Adhesions were the most prevalent complication in our research group, followed by intraoperative hemorrhage. To reduce related problems, the number of CSs must be reduced. The patient should be advised that vaginal birth after CS is an option. [ABSTRACT FROM AUTHOR]

This article discusses the complications that can arise from a previous caesarean section, specifically focusing on the caesarean scar defect. It emphasizes the importance of recognizing and managing these complications, as they can occur even after a successful vaginal birth after caesarean section. The article describes the anatomical changes of the caesarean scar defect and its relationship with placenta accrete spectrum disorder. It also addresses the management of these complications during pregnancy, including a technique for myometrial uterine repair. The article provides case studies to demonstrate how knowledge of scar anatomy can be used to manage complications related to the caesarean scar defect. The authors suggest the potential benefit of dedicated teams in Obstetrics and Gynecology departments to manage scar complications and improve outcomes. [Extracted from the article]

Purpose: We hypothesized that among obese patients with a history of cesarean birth, a TOLAC is associated with decreased composite maternal adverse outcomes (CMAO) compared to planned repeat low transverse cesarean section (RLTCS). Methods: In this population-based cross-sectional study using the National Birth Certificate database from 2016 to 2020, we compared obese patients who attempted TOLAC at term (≥ 37 weeks estimated gestational age) to planned RLTCS. The primary outcome was a CMAO, defined as delivery complications, including intensive care unit (ICU) admission, uterine rupture, unplanned hysterectomy, or maternal blood transfusion. Results: Overall, 794,278 patients met inclusion criteria for the study; 126,809 underwent a TOLAC, and 667,469 had a planned RLTCS. The overall CMAO was significantly higher for patients undergoing TOLAC (9.0 per 1000 live births) compared to RLTCS (5.3 per 1000 live births; aRR 1.64, 95% CI 1.53–1.75). Conclusion: This data demonstrate that in obese patients with prior cesarean birth, a trial of labor is associated with increased maternal morbidity when compared to a planned repeat cesarean birth.

Background: Australia's caesarean rate is higher than Organisation for Economic Co‐operation and Development (OECD) average, and is rising. Vaginal birth after caesarean (VBAC) is safe for selected women. Midwifery continuity of care (CoC) is associated with higher rates of vaginal birth compared to other models; however, impacts on VBAC attempts and success are unknown. Aims: The primary aim was to determine if there is a difference in achieving VBAC between CoC and non‐CoC (NCoC) models. The secondary aim was to determine if there is a difference in the proportion of women attempting VBAC between these models. Materials and Methods: Retrospective review of antenatal records and birthing data of all women who birthed in 2021 with one or more previous caesareans. Women were included if they had two or fewer caesareans. Women were excluded if contraindications to VBAC existed. Results: There were 142/1109 (12.8%) women who had previous caesareans and were eligible to attempt VBAC. There were 47/109 (43.1%) women who attempted vaginal birth after one caesarean with 78.7% success. After one caesarean, women in CoC were more likely to achieve VBAC than NCoC (45.2% vs 26.1%; relative risk (RR) 1.76, 95% CI 1.04–3.00), although when stratified by private and midwifery CoC models, women in midwifery CoC models were more likely to be successful (private RR 0.69, 95% CI 0.23–2.07 vs midwifery RR 2.48, 95% CI 1.50–4.11). Women in CoC were more likely to attempt VBAC (54.7% vs 34.8%; RR 1.57, 95% CI 1.02–2.41), and receive counselling about VBAC (92.5% vs 62%; RR 1.48, 95% CI 1.41–3.11). Conclusion: CoC improves the rate of attempted and successful VBAC through several factors, including increased counselling and greater provision of birth choices. [ABSTRACT FROM AUTHOR]

Background: Vesicouterine fistula (VUF) is a iatrogenic injury in the vast majority of cases. The worldwide increase of cesarean delivery rates is expected to lead to increased complications. Objectives: To assess current evidence on VUF pathogenesis and surgical management. Search Strategy: Pubmed and Embase databases were searched from January 2000 to January 2023 using relevant key words. Selection Criteria: Only original articles including either transabdominal or transvaginal surgical routes for post‐cesarean VUF repair, in English language, were included. Data Collection and Analysis: Two authors independently screened the references for eligibility, data extraction, and assessment of methodologic quality. All available surgical outcomes were recorded. Main Results: Of the 1160 studies retrieved, 67 were selected for analysis. Most of these were case reports, case series, or observational cohort studies including a total of 284 patients. The majority (78.6%) of patients had more than one cesarean section, and approximately 10% of them experienced an overt bladder injury and/or uterine rupture at the time of cesarean delivery. The supratrigonal part of the bladder was most commonly involved (92.5%). The majority of patients (88.8%) underwent delayed VUF repair through laparotomy. Length of stay and blood loss were significantly less in patients treated via a minimally invasive approach (P < 0.001 and P = 0.02, respectively). Most patients had double‐layer bladder repair and single‐layer uterine repair. The overall success rate was 100% on first attempt for each independent combination of different surgical approaches and techniques. Live birth following VUF repair was reported in 23 patients. Conclusions: Paying close attention to surgical details is crucial to reduce the incidence of this complication and recurrence rates. Double‐layer bladder closure and delayed timing of repair of VUF are recommended. Synopsis: Delayed repair of vesicouterine fistula avoiding endometrial exposure and using a double‐layer bladder closure are the most important surgical tenets of vesicouterine fistula repair.

Background: Globally, cesarean birth rates are rising, and while it can be a lifesaving procedure, cesarean birth is also associated with increased maternal and perinatal risks. This study aims to describe changes over time about the mode of birth and perinatal outcomes in second‐pregnancy women with one previous cesarean birth in the Netherlands over the past 20 years. Methods: We conducted a nationwide, population‐based study using the Dutch perinatal registry. The mode of birth (intended vaginal birth after cesarean (VBAC) compared with planned cesarean birth) was assessed in all women with one previous cesarean birth and no prior vaginal birth who gave birth to a term singleton in cephalic presentation between 2000 and 2019 in the Netherlands (n = 143,146). The reported outcomes include the trend of intended VBAC, VBAC success rate, and adverse perinatal outcomes (perinatal mortality up to 7 days, low Apgar score at 5 min, asphyxia, and neonatal intensive care unit admission ≥24 h). Results: Intended VBAC decreased by 21.5% in women with one previous cesarean birth and no prior vaginal birth, from 77.2% in 2000 to 55.7% in 2019, with a marked deceleration from 2009 onwards. The VBAC success rate dropped gradually, from 71.0% to 65.3%, across the same time period. Overall, the cesarean birth rate (planned and unplanned) increased from 45.2% to 63.6%. Adverse perinatal outcomes were higher in women intending VBAC compared with those planning a cesarean birth. Perinatal mortality initially decreased but remained stable from 2009 onwards, with only minimal differences between both modes of birth. Conclusions: In the Netherlands, the proportion of women intending VBAC after one previous cesarean birth and no prior vaginal birth has decreased markedly. Particularly from 2009 onwards, this decrease was not accompanied by a synchronous reduction in perinatal mortality. [ABSTRACT FROM AUTHOR]
