Abstract
OBJECTIVE This study aimed to determine whether a trial of labor after two cesarean deliveries (TOLAC2) increases the risk of adverse maternal and neonatal outcomes and identify prognostic factors for TOLAC2 success. STUDY DESIGN A retrospective cohort study was conducted at a single medical center. The study group was comprised of women with a history of TOLAC2. Outcomes were compared with women undergoing trial of labor after one previous cesarean delivery (TOLAC1). The primary outcome was trial of labor after cesarean delivery (TOLAC) success. Secondary outcomes included mode of delivery, uterine rupture, and combined adverse outcome (CAO; uterine rupture, postpartum hemorrhage, 5-minute Apgar score < 7, pH < 7.1). Logistic regression was used for the multivariate analysis to identify prognostic factors for TOLAC2 success. RESULTS A total of 381 women who underwent TOLAC2 were compared with 3,635 women who underwent TOLAC1. Women attempting TOLAC2 were less likely to achieve vaginal births after cesarean delivery (VBAC; 80.8 and 92.5%; odds ratio [OR]: 0.35; 95% confidence interval [CI]: 0.26-0.47; p < 0.001) and more likely to experience uterine rupture (0.8 vs. 0.2%; OR: 4.1; 95% CI: 1.1-15.9; p = 0.02) but not CAO (4.2 vs. 4.8%; OR: 0.88; 95% CI: 0.5-1.5; p = 0.3). TOLAC2 women with no previous vaginal deliveries had a lower chance of VBAC and a higher risk of uterine rupture compared with TOLAC1 women without a prior vaginal delivery (45.2 vs. 86.3%; OR: 0.13; 95% CI: 0.07-0.25; p < 0.001; 2.3 vs. 0%) and TOLAC2 women with a prior vaginal delivery (45.2 vs. 85.3%; OR: 0.14; 95% CI: 0.1-0.3; p < 0.0001; 2.4 vs. 0.6%; OR: 4.1; 95% CI: 0.4-46.3; p = 0.3). Multivariate analysis revealed that a history of vaginal delivery is an independent predictor of TOLAC2 success. CONCLUSION Women attempting TOLAC2 are less likely to achieve VBAC and are at greater risk of uterine rupture compared with those attempting TOLAC1. Despite these risks, the overall success rates remain very high, and the absolute risk of adverse outcomes is still very low. Prior vaginal delivery seems to have a protective effect on TOLAC outcomes. These data should be used to counsel women and assist in decision-making when considering the mode of delivery in women with two previous cesarean sections. KEY POINTS · TOLAC2 has a lower chance of success and higher rate of uterine rupture compared with TOLAC1.. · Previous vaginal delivery is an independent predictor of TOLAC2 success.. · Overall TOLAC2 outcomes are associated with high chances of success and low risk of uterine rupture..

Am J Obstet Gynecol MFM 2024; 6:101209. [PMID: 38536661 DOI: 10.1016/j.ajogmf.2023.101209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/22/2023] [Accepted: 10/26/2023] [Indexed: 05/12/2024]
Abstract
BACKGROUND Trial of labor after cesarean after 2 cesarean deliveries is linked to a lower success rate of vaginal delivery and higher rates of adverse obstetrical outcomes than trial of labor after cesarean after 1 previous cesarean delivery. OBJECTIVE This study aimed to investigate the factors associated with failed trial of labor after cesarean among women with 2 previous cesarean deliveries. STUDY DESIGN This was a multicenter retrospective cohort study, which included all women with singleton pregnancies attempting trial of labor after cesarean after 2 previous cesarean deliveries between 2003 and 2021. This study compared labor, maternal, and neonatal characteristics between women with failed trial of labor after cesarean and those with successful trial of labor after cesarean. Univariate analysis was initially performed, followed by multivariable analysis (adjusted odds ratios with 95% confidence intervals). RESULTS The study included a total of 1181 women attempting trial of labor after cesarean after 2 previous cesarean deliveries. Among these cases, vaginal birth after cesarean was achieved in 973 women (82.4%). Women with failed trial of labor after cesarean had higher rates of maternal and neonatal morbidities. Several factors were found to be associated with failed trial of labor after cesarean, including longer interpregnancy and interdelivery intervals, lower gravidity and parity, lower rates of previous successful vaginal delivery, smoking, earlier gestational age at delivery (38.3±2.1 vs 39.5±1.3 weeks), late preterm delivery (34-37 weeks of gestation), lower cervical dilation on admission, no use of epidural, and smaller neonatal birthweight. Our multivariable model revealed that late preterm delivery (adjusted odds ratio, 3.79; 95% confidence interval, 1.37-10.47) and cervical dilation on admission for labor <3 cm (adjusted odds ratio, 2.58; 95% confidence interval, 1.47-4.54) were associated with higher odds of failed trial of labor after cesarean. CONCLUSION In the investigated population of women with 2 previous cesarean deliveries undergoing trial of labor after cesarean, admission at the late preterm period with a cervical dilation of <3 cm, which reflects the latent phase, may elevate the risk of failed trial of labor after cesarean and a repeated intrapartum cesarean delivery.

Deshmukh U, Denoble AE, Son M. Trial of labor after cesarean, vaginal birth after cesarean, and the risk of uterine rupture: an expert review. Am J Obstet Gynecol 2024; 230:S783-S803. [PMID: 38462257 DOI: 10.1016/j.ajog.2022.10.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 10/21/2022] [Accepted: 10/21/2022] [Indexed: 03/12/2024]
Abstract
The decision to pursue a trial of labor after cesarean delivery is complex and depends on patient preference, the likelihood of successful vaginal birth after cesarean delivery, assessment of the risks vs benefits of trial of labor after cesarean delivery, and available resources to support safe trial of labor after cesarean delivery at the planned birthing center. The most feared complication of trial of labor after cesarean delivery is uterine rupture, which can have catastrophic consequences, including substantial maternal and perinatal morbidity and mortality. Although the absolute risk of uterine rupture is low, several clinical, historical, obstetrical, and intrapartum factors have been associated with increased risk. It is therefore critical for clinicians managing patients during trial of labor after cesarean delivery to be aware of these risk factors to appropriately select candidates for trial of labor after cesarean delivery and maximize the safety and benefits while minimizing the risks. Caution is advised when considering labor augmentation and induction in patients with a previous cesarean delivery. With established hospital safety protocols that dictate close maternal and fetal monitoring, avoidance of prostaglandins, and careful titration of oxytocin infusion when induction agents are needed, spontaneous and induced trial of labor after cesarean delivery are safe and should be offered to most patients with 1 previous low transverse, low vertical, or unknown uterine incision after appropriate evaluation, counseling, planning, and shared decision-making. Future research should focus on clarifying true risk factors and identifying the optimal approach to intrapartum and induction management, tools for antenatal prediction, and strategies for prevention of uterine rupture during trial of labor after cesarean delivery. A better understanding will facilitate patient counseling, support efforts to improve trial of labor after cesarean delivery and vaginal birth after cesarean delivery rates, and reduce the morbidity and mortality associated with uterine rupture during trial of labor after cesarean delivery.

Abstract
Introduction With the current surge on peripheral nerve blocks in post-cesarean pain management and the historical lack of unequivocal evidence supporting its universal use, this review intended to re-examine the extended scope of literature on regional anesthesia and postoperative analgesia in low-transverse cesarean section. Methods A literature search was conducted up to April 2023 using PubMed to identify articles relevant to our search words "cesarean section", "neuraxial morphine", "post-cesarean analgesia", as well as the name of each individual nerve block. The literature search was ultimately narrowed to systematic reviews and randomized controlled trials published between 2012 and 2023. We define, describe, and discuss the evidence surrounding each individual regional anesthetic technique in the presence and absence of intrathecal morphine, which is used as the gold standard when appropriate. Results In the absence of neuraxial morphine, all regional anesthetic techniques have some level of analgesic benefit in the post-cesarean analgesia. Transversus Abdominis Plane blocks continue to have the most studies in their use. Newer fascia plane blocks including the anterior Quadratus Lumborum, and Erector Spinae Plane blocks provide significant analgesia. In addition, direct comparison among peripheral nerve blocks consistently favors the more proximal, centralized techniques. Conversely, in the presence of neuraxial morphine, no peripheral anesthetic technique has reliably and reproducibly demonstrated an added analgesic benefit regardless of the peripheral nerve block technique or location of local anesthetic injection in the post-cesarean population. Conclusion Neuraxial morphine continues to be the gold standard for post-cesarean section analgesia, the benefit of additional single injection regional anesthetic is currently not evidence supported. In cases where neuraxial opioids have not or cannot be given, there is overwhelming evidence that regional anesthetic techniques improve post-cesarean section analgesia and decrease post-operative opioid consumption. Even though there is no consensus on the optimal peripheral nerve block, emerging evidence suggests more centralized abdominal fascia plane block trends towards better analgesia.

Abstract
BACKGROUND Uterine rupture is associated with clinically significant uterine bleeding, fetal distress, expulsion or protrusion of the fetus, placenta or both into the abdominal cavity requiring prompt cesarean delivery and uterine repair or hysterectomy. Previous cesarean section is the most common risk factor. The most consistent early indicator of it is the onset of prolonged and profound fetal bradycardia. OBJECTIVE In this study, we present six cases of uterine rupture highlighting risk factors, and challenges in diagnosis and management, along with a review of the literature. METHOD A retrospective case series identified eight cases during the five-year study period. All cases from January 1, 2018 to December 31, 2022 were reviewed. Cases with multiple previous cesarean sections were excluded. RESULT Six cases meeting the study criteria were included in our case series. Uterine rupture was a rare occurrence with a prevalence of nine in 31,315 births representing 0.03% of deliveries. No maternal mortality or need for hysterectomy occurred in our study. Fifty percent of uterine ruptures were associated with stillbirths. The most common risk factor was a previous cesarean section in 83.3%. The most common presenting sign was non-reassuring fetal status patterns in 66.6%. A single case had a silent rupture. CONCLUSION Signs and symptoms of uterine rupture are nonspecific making diagnosis challenging. Delay in definitive management causes significant fetal morbidity and mortality. For best outcomes, vaginal birth after a previous cesarean section needs close monitoring in appropriately prepared units with the ability to perform immediate cesarean delivery and provide advanced neonatal support.

Abstract
BACKGROUND The risks of a few maternal and/or neonatal morbidities are higher with the trial of labour after caesarean (TOLAC) owing to unplanned caesarean delivery. Thus, it is imperative to consider the trade-off between the risk of side effects and the potential benefits before TOLAC utilisation and whether TOLAC should be provided to women with specific characteristics related to previous caesarean delivery. We aimed to investigate maternal and neonatal characteristics associated with TOLAC utilisation, compare maternal and/or neonatal morbidities in TOLAC women with women who chose planned caesarean deliveries, and assess specific characteristics related to maternal and/or neonatal morbidities in women with TOLAC utilisation. METHODS In this retrospective cohort study, we used nationwide, linked birth and infant death data in the United States between 2012 and 2020, which covers all 50 states in the US. Poisson regression models using generalised estimating equations yielded adjusted prevalence ratios (aPRs) with 95% confidence intervals (CIs) of TOLAC utilisation and unsuccessful TOLAC by maternal and neonatal characteristics. Logistic regression models using generalised estimating equations yielded adjusted odds ratios (aORs) with 95% CIs of maternal and neonatal morbidities. Statistical analysis was performed from February 2022 to July 2022. FINDINGS The sample included 4,898,441 women with mean (SD) maternal age years (5.4 years; range 13-50). Several specific maternal and neonatal characteristics were significantly associated with unsuccessful TOLAC, although women with TOLAC utilisation were associated with significantly lower risks of maternal unplanned hysterectomy (aOR, 0.60; 95% CI, 0.60-0.61), admission to intensive care (aOR, 0.84; 95% CI, 0.84-0.85), and neonatal seizures (aOR, 0.80; 95% CI, 0.74-0.84). In women who attempted TOLAC, advanced maternal age, higher maternal body mass index, more than 2 previous caesarean deliveries, having maternal co-morbidities and fetal malpresentation increased the likelihood of maternal and neonatal morbidities. INTERPRETATION When utilising TOLAC, specific maternal and neonatal characteristics in pregnant women should be considered in conjunction with the potential benefits of TOLAC in preventing maternal and neonatal morbidities.

Abstract
BACKGROUND The goal of this study was to investigate whether pregnancy complications are associated with an increased risk of uterine rupture (UR) and how that risk changes with gestational age. METHODS We obtained all data from China's National Maternal Near Miss Surveillance System (NMNMSS) between 2012 and 2018. Poisson regression analysis was used to assess the risk of UR with pregnancy complications (preeclampsia, gestational diabetes mellitus, placental abruption, placenta previa and placenta percreta) among 9,454,239 pregnant women. Furthermore, we analysed the risks of UR with pregnancy complications in different gestational age groups. RESULTS The risk of UR was increased 2.0-fold (1.2-fold to 2.7-fold) in women with pregnancy complications (except for preeclampsia). These associations also persisted in women without a previous caesarean delivery. Moreover, an increased risk of UR before term birth was observed among women with gestational diabetes mellitus, placental abruption and placenta percreta. The risk of UR was slightly higher in women with gestational diabetes mellitus who had a large for gestational age (LGA) foetus, especially at 32 to 36 weeks gestation. CONCLUSIONS The risk of UR is associated with gestational diabetes mellitus, placental abruption, placenta previa and placenta percreta, but varies in different gestational ages.

Abstract
OBJECTIVE Trial of labor after cesarean delivery has been mostly studied in the setting of one prior cesarean delivery; controversy remains regarding the risks and benefits of trial of labor for women with two prior cesarean deliveries. This study aimed to examine utilization, success rate, and maternal and neonatal outcomes of trial of labor in this population. METHODS Using linked hospital discharge and birth certificate data, we retrospectively analyzed a cohort of mothers with nonanomalous, term, singleton live births in California between 2010-2012 and had two prior cesarean deliveries and no clear contraindications for trial of labor. We measured whether they attempted labor and, if so, whether they delivered vaginally. Association of patient and hospital characteristics with the likelihood of attempting labor and successful vaginal birth was examined using multivariable regressions. We compared composite severe maternal morbidities and composite severe newborn complications in those who underwent trial of labor as opposed to planned cesarean delivery using a propensity score-matching approach. RESULTS Among 42,771 women who met sample eligibility criteria, 1,228 (2.9%) attempted labor, of whom 484 (39.4%) delivered vaginally. There was no significant difference in the risk of composite severe maternal morbidities, but there was a modest increase in the risk of composite severe newborn complications among women who attempted labor compared with those who did not (2.0% vs 1.4%, P=.04). After accounting for differences in patient and hospital characteristics, propensity score-matched analysis showed no significant association between trial of labor and the risk of composite severe maternal morbidities (odds ratio [OR] 1.16, 95% CI 0.70-1.91), but trial of labor was associated with a higher risk for the composite of severe newborn complications (OR 1.78, 95% CI 1.04-3.04). CONCLUSION Among women with two prior cesarean deliveries, trial of labor was rarely attempted and was successful in 39.4% of attempts. Trial of labor in this population was associated with a modest increase in severe neonatal morbidity.

Abstract
The objective of this study is to evaluate the maternal and neonatal outcomes of parturients attempting trial of labor (TOL) after two previous CD versus those who had an elective third repeat CD. A retrospective computerized database cohort study was conducted at a single tertiary center between 2005 and 2019. Various maternal and neonatal outcomes were compared between parturients attempting TOL after two CD versus parturients opting for elective third repeat CD. TOL after two CD was allowed only for those who met all the criteria of our departments' protocol. Parturients with identified contraindication to vaginal delivery were excluded from the analysis. A univariate analysis was conducted and was followed by a multivariate analysis. A total of 2719 eligible births following two CD were identified, of which 485 (17.8%) had attempted TOL. Successful vaginal delivery rate following two CDs was 86.2%. Uterine rupture rates were higher among those attempting TOL (0.6% vs 0.1% p = 0.04). However, rates of hysterectomy, re-laparotomy, blood product infusion, and intensive care unit admission did not differ significantly between the groups. Neonatal outcomes following elective repeat CD were less favorable (specifically, neonatal intensive care unit admission and composite adverse neonatal outcome). Nonetheless, when controlling for potential confounders, an independent association between composite adverse neonatal outcome and an elective repeat CD was not demonstrated. In a subgroup analysis, diabetes mellitus and hypertensive disorders of pregnancy were found independently associated with failed TOLAC. When following a strict protocol, TOL after two CD is a reasonable alternative and associated with favorable outcomes.

Abstract
OBJECTIVE Trial of labor after cesarean delivery (TOLAC) is a common practice worldwide but the evidence is still scant regarding this practice in women who underwent 2 previous cesareans. The purpose of this study is to retrospectively review our experience with vaginal birth after two previous cesarean sections (VBA2C), with specific attention to the indications for previous cesarean and to the women's motivation for attempting trial of labor. STUDY DESIGN This was a retrospective cohort study conducted in a primary care hospital between January 2011 and December 2019. Inclusion criteria were: singleton pregnancies, absence of morphological abnormalities at ultrasonographic screening of the second trimester (or at any other stage of pregnancy), and two previous cesarean sections. RESULTS The final analysis included 114 cases for maternal and neonatal outcomes. In total, 40.4% of women chose trial of labor after two cesarean delivery (TOLA2C group). TOLA2C was associated with a success rate of 76.1%, a higher gestational age at birth, and a shorter hospital stay, compared with elective repeated cesarean delivery group. There were no significant differences in the rate of Apgar scores at 5 minutes <7 between both groups. The percentage of successful TOLA2C in women with prior vaginal delivery was 92.8%. Factors related to failed TOLA2C included failure to progress (3/11, 27.3%), nonreassuring fetal heart rate (3/11, 27.3%), and no onset of spontaneous labor after premature rupture of membranes (5/11, 45.4%). In the group of TOLA2C, more than 70% accepted to travel more than 45 minutes to reach our hospital, with the aim to attempt VBA2C. CONCLUSION TOLA2C is a possible option for both mothers and neonates in selected cases. Adequate counseling about pros and cons of TOLA2C is mandatory. The woman's motivation represents a key element to determine the success of VBA2C. KEY POINTS · Selection of candidates and motivation of the patients represent key elements for successful TOLA2C.. · A careful record of obstetrical history and previous deliveries can provide clinicians useful information.. · Mode of delivery in women with two previous cesareans is strongly associated with doctor's counseling..

Abstract
OBJECTIVE Over the past few decades, the rate of repeat cesarean deliveries (CD) have taken on pandemic proportions. As part of the global effort to reduce the rate of CD, trail of labor (TOL) following one and even two previous CDs is encouraged. We aimed to evaluate maternal and neonatal outcomes of parturients attempting a TOL after two previous CDs, in which a strict departmental protocol was adopted. STUDY DESIGN A retrospective cohort study of TOL following CD (TOLAC) at a single tertiary center, between 2005 and 2019. Various maternal and neonatal outcomes were assessed, in which parturients attempting TOL after two CD were compared to those after one previous CD. TOL after two CDs was permitted only to those parturients who fulfilled all the criteria of our department's protocol. A univariate analysis was initially conducted and was then followed by a multivariate analysis. RESULTS A total of 11,620 TOLAC were identified, of which 515 (4.4 %) were after two previous CDs. Overall, vaginal delivery rates were high, however, following two CDs the rate was lower than following one CD (83.1 % vs. 88.5 %, p < 0.01). Rates of uterine rupture, peripartum hysterectomy, and postpartum hemorrhage did not differ significantly between the groups. Neonatal results following two CDs were less favorable (specifically, one minute APGAR, neonatal care unit admissions and mechanical ventilation rates), yet, when controlling for potential confounders, an independent association between neonatal composite outcome and TOL following two CDs was not demonstrated. CONCLUSION For parturients with a history of two CDs, when a strict protocol for selecting appropriate candidates is followed, TOL is a reasonable alternative to repeat CD and is associated with favorable maternal and neonatal outcomes.

Abstract
Background A trial of labor after cesarean delivery is associated with uterine rupture rates of 0.5 to 0.9%, which can have devastating neonatal and maternal consequences. While uterine rupture typically occurs during labor, it can clinically manifest after delivery. Case A 23-year-old multiparous female presented in labor at term. Her obstetrical history was significant for a prior low transverse cesarean delivery. She had an uncomplicated labor course and spontaneous vaginal delivery. Immediately after delivery, she complained of severe right shoulder and left lower quadrant pain. Bedside ultrasound revealed a 10-cm, complex, adnexal mass adjacent to the uterus without free fluid. She was hemodynamically stable and appeared clinically well. On repeat ultrasound, the mass was unchanged; however, the patient now had free intraperitoneal fluid along the liver edge. Emergent laparotomy revealed a uterine rupture along her prior hysterotomy with extension into the right uterine artery. A 10-cm broad ligament hematoma ruptured posteriorly resulting in a 1-L hemoperitoneum. She received multiple blood products intraoperatively and recovered well postpartum. Conclusion Delivery after trial of labor after cesarean delivery usually decreases acuity; however, these patients remain at risk for significant complications. Clinicians should continue to assess patients in the immediate postpartum period and proceed with surgical intervention if necessary.

Abstract
Although there is no evidence that elevated rates of cesarean sections (CS) translate into reduced maternal/child perinatal morbidity or mortality, CS have been increasingly overused almost everywhere, both in high and low-income countries. The primary cesarean section (PCS) has become a major driver of the overall CS (OCS) rate, since it carries intrinsic risk of repeat CS (RCS) in future pregnancies. In our study we examined patterns of PCS, pl compared with planned TOLAC anned PCS (PPCS), vaginal birth after 1 previous CS (VBAC-1) and associated factors in Friuli Venezia Giulia (FVG), a region of North-Eastern Italy, collecting data from its 11 maternity centres (coded from A to K) during 2005-2015. By fitting three multiple logistic regression models (one for each delivery mode), we calculated the adjusted rates of PCS and PPCS among women without history of CS, whilst the calculation of the VBAC rate was restricted to women with just one previous CS (VBAC-1). Results, expressed as odds ratio (OR) with 95% confidence interval (95%CI), were controlled for the effect of hospital, calendar year as well as several factors related to the clinical and obstetric conditions of the mothers and the newborn, the obstetric history and socio-demographic background. In FVG during 2005-2015 there were 24,467 OCS (rate of 24.2%), 19,565 PCS (19.6%), 7,736 PPCS (7.7%) and 2,303 VBAC-1 (28.4%). We found high variability of delivery mode (DM) at hospital level, especially for PCS and PPCS. Breech presentation was the strongest determinant for PCS as well as PPCS. Leaving aside placenta previa/abuptio placenta/ante-partum hemorrhage, further significant factors, more importantly associated with PCS than PPCS were non-reassuring fetal status and obstructed labour, followed by (in order of statistical significance): multiple birth; eclampsia/pre-eclampsia; maternal age 40-44 years; placental weight 600-99 g; oligohydramios; pre-delivery LoS 3-5 days; maternal age 35-39 years; placenta weight 1,000-1,500 g; birthweight < 2,000 g; maternal age ≥ 45 years; pre-delivery LoS ≥ 6 days; mother's age 30-34 years; low birthweight (2,000-2,500 g); polyhydramnions; cord prolaspe; ≥6 US scas performed during pregnancy and pre-term gestations (33-36 weeks). Significant factors for PPCS were (in order of statistical significance): breech presentation; placenta previa/abruptio placenta/ante-partum haemorrhage; multiple birth; pre-delivery LoS ≥ 3 days; placental weight ≥ 600 g; maternal age 40-44 years; ≥6 US scans performed in pregnancy; maternal age ≥ 45 and 35-39 years; oligohydramnios; eclampsia/pre-eclampsia; mother's age 30-34 years; birthweight <2,000 g; polyhydramnios and pre-term gestation (33-36 weeks). VBAC-1 were more likely with gestation ≥ 41 weeks, placental weight <500 g and especially labour analgesia. During 2005-2015 the overall rate of PCS in FVG (19.6%) was substantially lower than the corresponding figure reported in 2010 for the entire Italy (29%) and still slightly under the most recent national PCS rate for 2017 (22.2%). The VBAC-1 rate on women with history of one previous CS in FVG was 28.4% (25.3% considering VBAC on all women with at least 1 previous CS), roughly three times the Italian national rate of 9% reported for 2017. The discrepancy between the OCS rate at country level (38.1%) and FVG's (24.2%) is therefore mainly attributable to RCS. Although there was a marginal decrease of PCS and PPCS crudes rates over time in the whole region, accompained by a progressive enhancement of the crude VBAC rate, we found remarkable variability of DM across hospitals. To further contain the number of unnecessary PCS and promote VBAC where appropriate, standardized obstetric protocols should be introduced and enforced at hospital level. Decision-making on PCS should be carefully scrutinized, introducing a diagnostic second opinion for all PCS, particularly for term singleton pregancies with cephalic presentation and in case of obstructed labour as well as non-reassuring fetal status, grey areas potentially affected by subjective clinical assessment. This process of change could be facilitated with education of staff/patients by opinion leaders and prenatal counseling for women and partners, although clinical audits, financial penalties and rewards to efficient maternity centres could also be considered.

Abstract
Trial of labor after cesarean delivery (TOLAC) refers to a planned attempt to deliver vaginally by a woman who has had a previous cesarean delivery, regardless of the outcome. This method provides women who desire a vaginal delivery the possibility of achieving that goal-a vaginal birth after cesarean delivery (VBAC). In addition to fulfilling a patient's preference for vaginal delivery, at an individual level, VBAC is associated with decreased maternal morbidity and a decreased risk of complications in future pregnancies as well as a decrease in the overall cesarean delivery rate at the population level (). However, although TOLAC is appropriate for many women, several factors increase the likelihood of a failed trial of labor, which in turn is associated with increased maternal and perinatal morbidity when compared with a successful trial of labor (ie, VBAC) and elective repeat cesarean delivery (). Therefore, assessing the likelihood of VBAC as well as the individual risks is important when determining who is an appropriate candidate for TOLAC. Thus, the purpose of this document is to review the risks and benefits of TOLAC in various clinical situations and to provide practical guidelines for counseling and management of patients who will attempt to give birth vaginally after a previous cesarean delivery.

Abstract
Background: Uterine rupture is an obstetric complication with high rates of associated maternal and neonatal morbidity and mortality. However, limited guidance for the timing of delivery in women with a history of prior uterine rupture exists.Objective: To determine the optimal gestational age of delivery in women with prior uterine rupture.Study design: A decision-analytic model was built using TreeAge software to compare the outcomes of repeat cesarean delivery when performed at 32, 33, 34, 35, or 36 weeks gestation in a theoretical cohort of 1000 women with prior uterine rupture. Strategies involved expectant management until a later gestational age accounting for the risks of spontaneous uterine rupture, spontaneous labor, uterine rupture following spontaneous labor, and stillbirth during each successive week that a woman was still pregnant. Maternal outcomes included uterine rupture, hysterectomy, and death. Neonatal outcomes included hypoxic-ischemic encephalopathy, cerebral palsy, and death. Probabilities were derived from the literature and total quality-adjusted life years (QALYs) were calculated. Sensitivity analyses were used to vary model inputs to investigate the robustness of our baseline assumptions.Results: In our theoretical cohort of 1000 pregnant women with a history of prior uterine rupture, cesarean delivery at 34 weeks maximized maternal and neonatal QALYs. Compared to delivery at 36 weeks, delivery at 34 weeks would prevent 38.6 uterine ruptures, 0.079 maternal deaths, 6.10 hysterectomies, and 12.1 neonatal deaths but results in 4.70 more cases of cerebral palsy. Univariate sensitivity analysis found that repeat cesarean at 34 weeks remained the optimal strategy until the probability of spontaneous repeat uterine rupture (baseline estimate: 0.68%) fell below 0.2% or rose above 0.9%, at which point, a strategy of delivery at 35 or 32 weeks became optimal, respectively. However, Monte Carlo simulation demonstrated that delivery at 35 weeks was the optimal strategy 37% of the time, whereas 34 weeks was the optimal strategy 17% of the time.Conclusion: The optimal time for repeat cesarean delivery in women with prior uterine rupture appears to be between 34-0/7 and 35-6/7 weeks gestation.

Abstract
BACKGROUND The OptiBIRTH study incorporates a multicentre cluster randomised trial in 15 hospital sites across three European countries. The trial was designed to test a complex intervention aimed at improving vaginal birth after caesarean section (VBAC) rates through increasing women's involvement in their care. Prior to developing a robust standardised model to conduct the health economic analysis, an analysis of a hypothetical cohort was performed to estimate the costs and health effects of VBAC compared to elective repeat caesarean delivery (ERCD) for low-risk women in four European countries. METHODS A decision-analytic model was developed to estimate the costs and the health effects, measured using Quality Adjusted Life Years (QALYs), of VBAC compared with ERCD. A cost-effectiveness analysis for the period from confirmation of pregnancy to 6 weeks postpartum was performed for short-term consequences and during lifetime for long-term consequences, based on a hypothetical cohort of 100,000 pregnant women in each of four different countries; Belgium, Germany, Ireland and Italy. A societal perspective was adopted. Where possible, transition probabilities, costs and health effects were adapted from national data obtained from the respective countries. Country-specific thresholds were used to determine the cost-effectiveness of VBAC compared to ERCD. Deterministic and probabilistic sensitivity analyses were conducted to examine the uncertainty of model assumptions. RESULTS Within a 6-week time horizon, VBAC resulted in a reduction in costs, ranging from €3,334,052 (Germany) to €66,162,379 (Ireland), and gains in QALYs ranging from 6399 (Italy) to 7561 (Germany) per 100,000 women birthing in each country. Compared to ERCD, VBAC is the dominant strategy in all four countries. Applying a lifetime horizon, VBAC is dominant compared to ERCD in all countries except for Germany (probabilistic analysis, ICER: €8609/QALY). In conclusion, compared to ERCD, VBAC remains cost-effective when using a lifetime time. CONCLUSIONS In all four countries, VBAC was cost-effective compared to ERCD for low-risk women. This is important for health service managers, economists and policy makers concerned with maximising health benefits within limited and constrained resources.

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 deliveries after cesarean section in our SONUC Health Centre. The quality of management should be enhanced through a better strategy in preparation for delivery. Trial of scar is a procedure to encourage in order to reduce the rate of iterative cesarean sections.

Abstract
Uterine dehiscence is the incomplete separation of the myometrium at a uterine scar site, usually from a previous cesarean section. Because membranes remain intact, the prognosis for both mother and fetus is generally good. However, labor contractions may lead to progression and a complete uterine rupture, which can be catastrophic. The combination of abdominal pain, previous cesarean section, and the sonographic finding of ballooning membranes should suggest the diagnosis of uterine dehiscence.

Abstract
Extracorporeal membrane oxygenation (ECMO) is increasingly used for the management of acute severe cardiac and respiratory failure. One of the indications is acute respiratory distress syndrome (ARDS) for which, in some severe cases, ECMO represents the only possibility to save lives. We report on the successful long-term use of ECMO in a postpartum patient with recurrent pulmonary decompensation after peripartum uterine rupture with extensive blood loss.

Abstract
OBJECTIVE The objective of this study is to evaluate maternal and neonatal outcomes associated with trial of labor after cesarean (TOLAC) in women with three prior cesarean delivery (CD) and at least one prior vaginal delivery. METHODS This is a retrospective study using data collected from clinical records of women three prior CD and at least one prior vaginal delivery who were referred to our unit. Maternal and perinatal outcomes were compared between women with three prior CD who underwent TOLAC and those who underwent planned repeated CD (i.e. control group). The primary outcome was a composite of maternal complications including at least one of the followings: need for blood transfusion, uterine rupture, hysterectomy, and admission to intensive care unit. RESULTS Fifty singleton gestations with three prior CD at with at least one prior vaginal birth were analyzed. Of them, 10 accepted to undergo TOLAC. Of the 10 women who underwent TOLAC, nine had vaginal birth and one had CD for non-reassuring pattern. We found no significant differences in the primary outcome, in need for blood transfusion, in the incidence of uterine rupture, hysterectomy, and admission to intensive care unit comparing TOLAC group with controls. CONCLUSION TOLAC in women with three prior CD and at least one prior vaginal delivery is a viable option and is not associated with higher risk of adverse maternal or fetal outcomes.

Abstract
To identify maternal, care provider, and institutional-level risk factors for early term (37-38 weeks) elective repeat cesarean delivery in a population-based cohort. Retrospective cohort study of women in the British Columbia (BC) Perinatal Data Registry, BC, Canada, 2008-2011, with an elective repeat cesarean delivery at term. Absolute percent differences (risk differences) in early term delivery rates were calculated according to maternal characteristics, type of care provider, calendar time (day of the week, time of year), and annual institutional obstetrical volume. Of the 7,687 elective repeat cesareans at term in BC, 55 % occurred before 39 + 0 weeks. Early term delivery was significantly more common with multiple previous cesareans [8.2 percentage points (95 % CI 5.5, 10.9) for 2 previous cesareans, 11.3 (95 % CI 5.1, 17.4) for 3 or more previous cesareans], obesity [6.7 percentage points (95 % CI 1.6, 11.7)], and a hospital obstetrical volume <2,500 deliveries per year. Type of care provider and calendar time were not significant risk factors for early term delivery. Early term elective repeat cesarean was common across a wide range of maternal, care provider, and institutional characteristics, suggesting that most obstetrical care settings would benefit from quality-improvement programs to reduce elective repeat cesarean deliveries before 39 weeks. A better understanding of the risks and benefits of early term delivery among obese women and women with multiple previous cesareans is needed given the higher rates of early term delivery observed in these women.

Abstract
OBJECTIVE To compare the quality of the uterine scar with one or two layer closure after caesarean section by studying biomechanical and pathological properties of the scar. METHODS A randomized controlled trial performed on eight term pregnant ewes assigned into two groups during caesarean according to type of uterine closure: single-layer or double-layer. Hysterectomy was performed 8 months after caesarean delivery. Tensile strength of all scars and of unscarred myometrium was measured. Pathological properties of the scars were analyzed histologically. RESULTS The force required to reach the yield point was similar between scarred and unscarred myometrium (p=0.96), and between the scars in single-layer and double-layer closure groups (p=0.65). There was a significant increase in fibrosis width on the superficial part of the uterus in the double-layer closure group compared to the single-layer group (p=0.02). CONCLUSIONS Double-layer uterine closure modified wound healing without significant change in biomechanical properties.

Abstract
OBJECTIVE To evaluate the significance of persistent lower abdominal pain in women with previous cesarean delivery. METHODS Various maternal outcomes were compared between women who underwent repeated cesareans owing to persistent lower abdominal pain (study group) and women who underwent repeated cesareans without persistent abdominal pain (control group). RESULTS The incidence of uterine rupture was significantly higher in the study group than in the control group (8/81 [9.9%] vs 0/119 [0.0%]; P<0.001). While all women with persistent lower abdominal pain and uterine rupture had an additional sign or symptom, only 6/73 (8.2%) women with persistent abdominal pain without uterine rupture had any additional symptoms (P<0.001). There was no difference in incidence of uterine scar dehiscence between the groups. However, the hospitalization period was significantly longer in the study group (4 vs 3.7days; P<0.05). Trial of labor was a contributing factor to uterine rupture. CONCLUSION Isolated persistent lower abdominal pain in women with previous cesarean is a poor indicator of uterine rupture. However, the positive predictive value for uterine rupture is 57% when an additional sign or symptom is present. Dehiscence of the uterine scar is relatively common and it is not associated with persistent abdominal pain.

Abstract
Trial of labor after cesarean (TOLAC) delivery is currently a hot obstetrical topic owing to the acute rise in the rate of cesarean deliveries, both primary and repeat. When the physician and patient are considering TOLAC, several factors should be considered: risk of uterine rupture, contraindications, minimizing risk and morbidity, choosing the appropriate candidate and whether or not to induce. Each patient has her own set of individual risk factors that may decrease her chance of successful vaginal birth after cesarean delivery or increase her risks with TOLAC. Once all things are considered, the risk:benefit of TOLAC should be weighed up before a decision is reached. Each of these factors is discussed in respect to maternal risk:benefit, with the focus on evidence presented in the current literature.

Abstract
AIM: To analyze the concept of risk in maternity care.DATA SOURCES: MEDLINE (1966–2010), CINAHL (1980–2010), EMBASE (1980–2010), PsycINFO (1980–2010), and Social Science Citation Index were searched. Key text books were sourced. Media literature was reviewed by perusal of newspaper articles, health supplements, and popular Internet health care websites.REVIEW METHODS: The principle-based method of concept analysis was used to guide the analysis of risk in maternity care.RESULTS: The epistemological principle identified the ambiguous nature of the risk concept, with risk having diverse meanings for different individuals. The pragmatic principle demonstrated that the current systematic approach to risk assessment often fails to identify those who succumb to risk issues. The linguistic principle portrays the ambiguity of risk perception with “risk” considered according to past experiences, knowledge, and individual attitudes. The logical principle identified a strong link between safety and uncertainty revealing that the risk concept lacks integrity and may not “hold its own.”CONCLUSION: The concept of risk in maternity care is concerned with risk assessment, risk perception, and notions of safety and uncertainty. Risk in maternity care is diverse and dynamic. What constitutes as a risk today may not necessarily be viewed in the same light tomorrow.

Abstract
Nearly 1 in 3 pregnant women in the United States undergo cesarean. This trend is contrary to the national goal of decreasing cesarean delivery in low-risk women. The decline in vaginal birth after cesarean (VBAC) contributes to the continual increase in cesarean deliveries. Prior cesarean delivery is the most common indication for cesarean and accounts for more than one-third of all cesareans. The appropriate use and safety of cesarean and VBAC are of concern not only at the individual patient and clinician level but they also have far-reaching public health and policy implications at the national level.

Abstract
Uterine rupture, which involves complete separation of the uterine wall, occurs in about 1% of those attempting vaginal birth after cesarean. Because uterine rupture is one of the most significant complications of a trial of labor (TOL) after previous cesarean, identifying those at increased risk of uterine rupture is paramount to the safety of a TOL after previous cesarean birth. It seems that both antepartum demographic characteristics and intrapartum factors modify the risk of uterine rupture. The ability to reliably predict an individual's a priori risk for intrapartum uterine rupture remains a major area of investigation.

Abstract
OBJECTIVE To evaluate existing vaginal birth after cesarean (VBAC) screening tools and to identify additional factors that may predict VBAC or failed trial of labor. DATA SOURCES Relevant studies were identified through MEDLINE, Database of Abstracts of Reviews of Effectiveness, and the Cochrane databases (1980-September 2009), and from recent systematic reviews, reference lists, reviews, editorials, web sites, and experts. METHODS OF STUDY SELECTION Inclusion criteria limited studies to those of humans, written in English, studies conducted in the United States and developed countries, and those rated good or fair quality by the U.S. Preventive Services Task Force criteria. Studies of individual predictors were combined using a random effects model when the estimated odds ratios were comparable across included studies. TABULATION, INTEGRATION, AND RESULTS We identified 3,134 citations and reviewed 963 papers, of which 203 met inclusion criteria and were quality-rated. Twenty-eight provided evidence on predictors of VBAC and 16 presented information on scored models for predicting VBAC (or failed trial of labor). Six of the 11 scored models for predicting VBAC (or failed trial of labor) were validated by separated dataset, cross-validation, or both. Whereas accuracy remained high across all models for predicting VBAC, with predictive values ranging from 88% to 95%, accuracy for predicting failed trial of labor was low, ranging from 33% to 58%. Individual predictors including Hispanic ethnicity, African-American race, advanced maternal age, no previous vaginal birth history, birth weight heavier than 4 kg, and use of either augmentation or induction were all associated with reduced likelihood of VBAC. CONCLUSION Current scored models provide reasonable predictability for VBAC, but none provides consistent ability to identify women at risk for failed trial of labor. A scoring model is needed that incorporates known antepartum factors and can be adjusted for current obstetric factors and labor patterns if induction or augmentation is needed. This would allow women and clinicians to better determine individuals most likely to require repeat cesarean delivery.

Abstract
The objective was to compare national guidelines regarding vaginal birth after cesarean. Along with the American College of Obstetricians and Gynecologists practice bulletin, guidelines from the Royal College of Obstetricians and Gynaecologists and the Society of Obstetricians and Gynecologists of Canada were reviewed and compared. Although the 3 organizations agree on most of the risk factors for uterine rupture and failed vaginal birth after cesarean (VBAC), there were some variances in the recommendations to women with 2 previous cesareans and those who required oxytocin augmentation. A disagreement was also present in regard to the availability and requirement of resources to allow a trial of labor after a previous cesarean. Although concerns could be raised about how the literature is synthesized, the 3 organizations recognized the potential biases in published reports and the lack of randomized trials.

Abstract
We sought to determine whether postcaesarean treatment with whey peptides (WP) affects the healing of skin and uterine incision in rats during puerperium. Forty-eight rats were randomly divided into two groups. After a caesarean section, twenty-four rats were intragastrically administered WP, while others were administered a control vehicle. On days 7, 14 and 21 after delivery, the serum total protein/albumin concentration, skin tensile strength, uterine bursting pressure, skin/uterine hydroxyproline (Hyp) concentration and histological characteristics of the scar were measured in eight rats in each group. In the WP group, the albumin concentration, skin tensile strength, uterine bursting pressure and Hyp concentration in the skin increased significantly on days 21, 7, 14 and 21, respectively. Low neutrophil count and smaller scar width in the skin incision were found in the WP group on day 7. Postcaesarean treatment with WP promoted significant wound healing in the skin incision, and had a significant wound healing potential in the uterus.

Abstract
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.
