Chen X, Mi MY. The impact of a trial of labor after cesarean versus elective repeat cesarean delivery: A meta-analysis. Medicine (Baltimore) 2024; 103:e37156. [PMID: 38363952 PMCID: PMC10869045 DOI: 10.1097/md.0000000000037156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 01/11/2024] [Indexed: 02/18/2024] Open
Abstract
BACKGROUND The increasing global incidence of cesarean section has prompted efforts to reduce cesarean delivery rates. A trial of labor after cesarean (TOLAC) has emerged as an alternative to elective repeat cesarean delivery (ERCD) for women with a prior cesarean delivery. However, the available evidence on the comparative outcomes of these 2 options remains inconsistent, primarily due to varying advantages and risks associated with each. Our meta-analysis aims to compare the maternal-neonatal results in TOLAC and ERCD in women with prior cesarean deliveries. METHODS A comprehensive search was performed in PubMed, Embase, Cochrane library databases up to September,2022 to identity studies evaluating perinatal outcomes in women who underwent TOLAC compared to ERCD following a previous cesarean delivery. The included studies were subjected to meta-analysis using RevMan 5.3 software to assess the overall findings. RESULTS A total of 13 articles were included in this meta-analysis. Statistically significant differences were identified in the rate of uterine rupture (OR = 2.01,95%CI = 1.48-2.74, P < .00001) and APGAR score < 7 at 5 minutes (OR = 2.17,95%CI = 1.69-2.77, P < .00001) between the TOLAC and ERCD groups. However, no significant differences were observed in the rates of hysterectomy, maternal blood transfusion, postpartum infection, postpartum hemorrhage and neonatal intensive care unit (P ≥ .05) admission between the 2 groups. CONCLUSIONS Our analysis revealed that TOLAC is associated with a higher risk of uterine rupture and lower incidence APGAR score < 7 at 5 minutes compared to ERCD. It is vital to consider predictive factors when determining the appropriate mode of delivery in order to ensure optimal pregnancy outcomes. Efforts should be made to identify the underlying causes of adverse outcomes and implement safety precautions to select suitable participants and create safe environments for TOLAC.

S H, V MA. An idiosyncratic MIMBO-NBRF based automated system for child birth mode prediction. Artif Intell Med 2023; 143:102621. [PMID: 37673564 DOI: 10.1016/j.artmed.2023.102621] [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: 01/27/2023] [Revised: 05/11/2023] [Accepted: 07/01/2023] [Indexed: 09/08/2023]
Abstract
Predicting the mode of child birth is still remains one of the most complex and challenging tasks in ancient times. Also, there is no such strong methodologies are developed in the conventional works for birth mode prediction. Therefore, the proposed work objects to develop a novel and distinct optimization based machine learning technique for creating the child birth mode prediction system. This framework includes the modules of data imputation, feature selection, classification, and prediction. Initially, the data imputation process is performed to improve the quality of dataset by normalizing the attributes and filling the missed fields. Then, the Multivariate Intensified Mine Blast Optimization (MIMBO) technique is implemented to choose the best set of features by estimating the optimal function. After that, an integrated Naïve Bayes - Random Forest (NBRF) technique is developed by incorporating the functions of conventional NB and RF techniques. The novel contribution of this technique, a Bird Mating (BM) optimization technique is used in NBRF classifier for estimating the likelihood parameter to generate the Bayesian rules. The main idea of this paper is to develop a simple as well as efficient automated system with the use of hybrid machine learning model for predicting the mode of child birth. For this purpose, advanced algorithms such as MIMBO based feature selection, and NBRF based classification are implemented in this work. Due to the inclusion of MIMBO and BM optimization techniques, the performance of classifier is greatly improved with low computational burden and increased prediction accuracy. Moreover, the combination of proposed MIMBO-NBRF technique outperforms the existing child birth prediction methods with superior results in terms of average accuracy up to 99 %. In addition, some other parameters are also estimated and compared with the existing techniques for proving the overall superiority of the proposed framework.

Abstract
Cesarean delivery rates have been steadily rising since the beginning of the 21st century. The growing incidence is even more prominent in developing countries owing to lack of evidence-based guidance and audit, and the expansion of private practice. The uprise in Cesarean delivery rate has been associated with considerable financial burden and has increased the risk otherwise uncommon serious complications such as placenta accreta disorders and uterine rupture. In addition to primary prevention of Cesarean delivery, trial of labor after cesarean section is one of the most successful strategies to reduce Cesarean deliveries and minimize risks associated with higher order Cesarean deliveries. This guideline appraises patient selection strategies and use of prediction model to promote counseling and enhance safety in women considering vaginal birth after Cesarean.

Predictors of Repeat Cesarean Section in Women with One Previous Lower Segment Cesarean Section: A Retrospective Study from Malaysia. SAUDI JOURNAL OF MEDICINE & MEDICAL SCIENCES 2023; 11:67-72. [PMID: 36909011 PMCID: PMC9997861 DOI: 10.4103/sjmms.sjmms_256_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 09/21/2022] [Accepted: 12/30/2022] [Indexed: 03/14/2023]
Abstract
Background The rates of repeat cesarean section (CS) among women with previous CS are increasing worldwide. The predictors of a repeat CS can vary across different populations. Objective To determine the predictors of repeat CS among women from Malaysia with one previous lower segment CS (LSCS) who underwent trial of labor (TOLAC). Materials and Methods This retrospective cohort study included women with one previous LSCS who followed up and delivered their current pregnancy at Hospital Universiti Sains Malaysia (USM), Kelantan, Malaysia, between January 01, 2016, and December 31, 2017. Women with singleton pregnancies were included while those who had a history of classical CS, current pregnancy with preterm birth, non-cephalic pregnancy, lethal fetal anomalies, uterine rupture, and severe preeclampsia or planned for elective CS were excluded. Logistic regressions were performed. Results The study included 388 women who underwent TOLAC and successfully gave childbirth through vaginal birth after cesarean (VBAC) (n = 194) or emergency LSCS (n = 194). Factors significantly associated with repeat CS were no history of vaginal delivery (adjusted odds ratio (aOR): 2.71; 95% confidence interval (CI): 1.60, 4.60; P < 0.001), estimated fetal weight ≥3500 grams (aOR: 4.78; 95% CI: 2.45-9.34; P < 0.001), and presence of meconium-stained liquor (aOR: 2.40; 95% CI: 1.33-4.35; P = 0.004). Conclusion The above-mentioned predictors of a repeat CS among women from Malaysia with one previous LSCS who underwent TOLAC can be useful for clinicians in making an informed decision.

Arch Gynecol Obstet 2022; 306:229-237. [PMID: 35347382 PMCID: PMC9300527 DOI: 10.1007/s00404-022-06436-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 02/04/2022] [Indexed: 11/02/2022]
Abstract
AbstractThe aim of this study was to explore whether the presence of intra-cavitary fluid (ICF) influences the pregnancy outcomes of patients with caesarean section (CS) in embryo transfer cycles. A total of 8494 transferred cycles of 4924 women were enrolled in this retrospective study and separated into three subgroups by previous delivery method and the presence of intra-cavity fluid, a caesarean group with ICF (CS-ICF, n = 649), a caesarean group without ICF (CS-noICF, n = 3207), and the remaining 4638 cycles without ICF were included in the vaginal delivered group (VD, n = 4638). Baseline characteristics and clinical outcome were compared. Propensity score matching (PSM) was conducted to adjust confounding factors between groups. Patients in the CS-ICF group were of younger age (36.49 ± 4.19 vs 37.34 ± 4.25, 37.32 ± 4.86, P < 0.001), had better ovary reserve, and had more blastocyst transferred compared with the CS-noICF and VD groups. However, cycles in the CS-ICF group achieved unsatisfactory clinical pregnancy outcomes. PSM analysis for comparability and differences in clinical outcomes still existed. The clinical pregnancy rate was significantly lower in the CS-ICF group than in the CS-noICF group (35.1% vs 41.7% for CS-noICF group, 48.1% for VD group, P < 0.001). Subgroup analysis of fresh embryo transferred cycles, the differences in clinical outcomes disappeared after PSM analysis, while the clinical pregnancy rate was still lowest among the three matched groups of FET cycles (36.4% vs 50.3% for VD group, P < 0.001). The presence of intra-cavitary fluid (ICF), but not necessarily the isthmocele, significantly compromises the clinical pregnancy rate in patients with previous CS undergoing IVF/ICSI treatment.

Abstract
Background Uterine rupture is an obstetrical emergency with serious undesired complications for laboring mothers resulting in fatal maternal and neonatal outcomes. The aim of this study was to assess the incidence of uterine rupture, its association with previous uterine surgery and vaginal birth after caesarean section (VBAC), and the maternal and perinatal implications. Methods This is a population-based retrospective study. All pregnant women treated for ruptured uterus in one center between 2013 and 2020 were included. Their information retrieved from the medical records department were reviewed retrospectively. Results A total of 209,112 deliveries were included and 41 cases of uterine rupture were identified. The incidence of uterine rupture was 1.96/10000 births. Among the 41 cases, 16 (39.0%) had maternal and fetal complications. There were no maternal deaths secondary to uterine rupture, while perinatal fatality related to uterine rupture was 7.3%. Among all cases, 38 (92.7%) were scarred uterus and 3 (7.3%) were unscarred uterus. The most common cause of uterine rupture was previous cesarean section, while cases with a history of laparoscopic myomectomy were more likely to have serious adverse outcomes, such as fetal death. 24 (59.0%) of the ruptures occurred in anterior lower uterine segment. Changes in Fetal heart rate monitoring were the most reliable signs for rupture. Conclusions Incidence of uterine rupture in the study area, Shanghai, China was consistent with developed countries. Further improvements in obstetric care and enhanced collaboration with referring health facilities were needed to ensure maternal and perinatal safety. Supplementary Information The online version contains supplementary material available at 10.1186/s12884-022-04415-6.

Abstract
Background Despite good access to antenatal care (ANC) services for most women, and regular training of healthcare workers in obstetrics and gynaecology, many pregnant women with a previous history of caesarean section (C/S) still presented late for ANC services at Letsholathebe II Memorial Hospital (LIIMH) in Maun, Botswana. This may increase morbidity and mortality in women with previous C/S delivery and neonates. Knowing why women with previous C/S present late for ANC may help in the formulation of interventions that decrease morbidity and mortality amongst these women and neonates. Aim The aim of this study was to explore the reasons why pregnant women with a previous history of C/S registered late for ANC, at LIIMH. Setting This study was performed at LIIMH, a district hospital situated in Maun, Botswana. Methods This was a descriptive qualitative study. Consenting pregnant women with previous C/S who presented at LIIMH after the 20 weeks of pregnancy were interviewed until data saturation. The data was analysed for themes. Results The reasons for late registration at LIIMH include lack of information, misconception on the appropriate booking time and venue, dissatisfaction with the quality of ANC clinic services, use of alternative ANC providers, delayed referral, and pregnancy experience. Conclusion Lack of knowledge of ANC delivery venue, using alternative ANC providers, and dissatisfaction with ANC clinic services, contributed to late registration. Pregnant women with previous history of C/S should be informed about ANC, delivery plans, and the assistance of alternative ANC providers should be explored.

Abstract
INTRODUCTION With the wide adoption of the two-child policy in China since 2016, a large percentage of women with a history of caesarean delivery plan to have a second child. Accordingly, the rate of vaginal birth after caesarean (VBAC) delivery is increasing. Women attempting repeat VBAC may experience multiple morbidities, which is also one of the leading causes of maternal and perinatal mortality. However, it remains to be addressed how we evaluate factors for successful VBAC. This study aims to use a novel approach to identify a set of potential predictive factors for successful VBAC, especially for Chinese women, to be included in prediction models which can be most applicable to pregnant women in China. We plan to assess all potential predictive factors collected through a comprehensive literature review. Then the certainty of the evidence for the identified potential predictive factors will be assessed using the Grading of Recommendations Assessment, Development and Evaluation process. Finally, a two-round international Delphi survey will be conducted to determine the level of consensus. METHODS AND ANALYSIS This study will apply a methodology through an evidence-based approach. A long list of potential predictive factors for successful VBAC will be extracted and identified through the following stages: First, an up-to-date systematic review of the published literature will be conducted to extract identified potential predictive factors for successful VBAC. Second, an online Delphi survey will be performed to achieve expert consensus on which factors should be included in future prediction models. The online questionnaires will be developed in the field of patient, maternal and fetal-related factors. A two-round international Delphi survey will be distributed to the expert panel in the field of perinatal medicine using Google Forms. Experts will be asked to score each factor using the 9-point Likert rating scale to establish potential predictive factors for the successful VBAC. The expert panel will determine on whether to include, potentially include or exclude predictive factors, based on a systematic review of clinical evidence and the Delphi method. ETHICS AND DISSEMINATION The study was approved by the Institutional Review Board of the Jiaxing Maternity and Children Healthcare Hospital (approval number: 2019-79). The results of this study will be submitted to international peer-reviewed journals or conferences in perinatal medicine or obstetrics.

Busumani W, Mundagowa PT. Outcomes of pregnancy-related referrals from rural health facilities to two central hospitals in Harare, Zimbabwe: a prospective descriptive study. BMC Health Serv Res 2021; 21:276. [PMID: 33766018 PMCID: PMC7993539 DOI: 10.1186/s12913-021-06289-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 03/16/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Between the years 2000 and 2017, the global maternal mortality rate dropped by 38% however, 94% of maternal deaths still emanated from low-to middle-income countries. Rural women are at a significantly higher risk of dying from pregnancy when compared to their urban counterparts. Early detection of complications and prompt referral to higher levels of care can reduce the associated maternal and perinatal mortality. This study aimed to determine the maternal and perinatal outcomes of pregnancy-related referrals from rural health facilities to central hospitals in Harare, Zimbabwe. METHODS A prospective descriptive study was conducted using a sample of 206 patients. All mothers who were referred from rural healthcare facilities were recruited for participation. Data were extracted from patient notes using a structured questionnaire and missing information was obtained from the mother after she had recovered. Bivariate analysis was done using IBM SPSS. RESULTS The average age of study participants was 27.4 ± 7.7 years. 87.4% had booked for antenatal care and 81.6% presented to the tertiary facility with their referral notes. The major reasons for referring patients were previous cesarean section (20.4%) and hypertensive disorders in pregnancy (18.4%). There were nine maternal deaths thus a case fatality rate of 4.4% while the perinatal mortality rate was 151/1000 live births. Young mothers were at a higher risk of having adverse perinatal outcomes while primiparous mothers were more likely to have a blood transfusion. Mothers who traveled for > 100 km to the tertiary facility and those who did not attend any antenatal visit were more likely to need blood transfusion. Delivering at the rural health facility was significantly associated with receiving a blood transfusion at the tertiary facility. Mothers who did not attend antenatal visits were more likely to have negative perinatal outcomes. CONCLUSION The proportion of obstetric patients being referred from rural facilities to tertiary institutions for complications reveals how primary and secondary healthcare facilities in Zimbabwe are falling short of offering the services they should be offering. Equipping these facilities with skilled human resources as well as contemporary equipment could help decongest the central hospitals consequently reducing the adverse maternal and perinatal outcomes.

Effect of shared decision making on mode of delivery and decisional conflict and regret in pregnant women with previous cesarean section: a randomized clinical trial. BMC Pregnancy Childbirth 2021; 21:144. [PMID: 33596854 PMCID: PMC7890798 DOI: 10.1186/s12884-021-03615-w] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 02/03/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The promotion of vaginal birth after cesarean section (VBAC) is the best method for the reduction of repeated cesarean sections. Nonetheless, the decisional conflict which often results from inadequate patient involvement in decision making, may lead to delayed decision making and regret about the choices that were made. The present study aimed to determine the effect of shared decision making on the mode of delivery and decisional conflict and regret in pregnant women with previous cesarean section. METHODS This randomized clinical trial was conducted on 78 pregnant women with a previous cesarean section referring to community health centers in Torbat-e Jam, Iran, in 2019. They were randomly assigned to two groups of intervention and control. During weeks 24-30 of pregnancy, the Decisional Conflict Scale (DCS) was completed by pregnant mothers. Apart from the routine care, the experimental group received a counseling session which was held based on the three-talk model of shared decision making. This session was moderated by a midwife; moreover, a complementary counseling session was administered by a gynecologist. During weeks 35-37 of pregnancy, DCS was completed, and the Decision Regret Scale (DRS) was filled out for both groups at the 8th weeks postpartum and they were asked about the mode of delivery. Data were analyzed in SPSS software (version 19) using the Mann-Whitney, Chi-squared and Fisher's exact tests. p-value less than 0.05 was considered statistically significant. RESULTS After the intervention, the decisional conflict score was significantly lower in the shared decision making (SDM) group, compared to that in the control group (14.90 ± 9.65 vs. 25.41 ± 13.38; P < 0.001). Moreover, in the SDM group, the rate of vaginal birth was significantly higher than that in the control group (P < 0.001). Two month after the delivery, the mean score of decision regret was lower in the SDM group, in comparison to that in the control group (15.67 ± 23.37 vs. 27. 30± 26.75; P = 0.007). CONCLUSIONS Based on the results of the study, shared counseling can be effective in the reduction of decisional conflict and regret, as well as rate enhancement of VBAC. Therefore, it can be concluded that this counseling method can be used in prenatal care to reduce the rate of repeated cesarean section.

Abstract
Background The rate of delivery by cesarean section is rising in China, where vaginal birth after cesarean (VBAC) is in its early stages. There are no validated screening tools to predict VBAC success in China. The objective of this study was to identify the variables predicting the likelihood of successful VBAC to create a predictive model. Material/Methods This multicenter, retrospective study included 1013 women at ≥28 gestational weeks with a vertex singleton gestation and 1 prior low-transverse cesarean from January 2017 to December 2017 in 11 public tertiary hospitals within 7 provinces of China. Two multivariable logistic regression models were developed: (1) at a first-trimester visit and (2) at the pre-labor admission to hospital. The models were evaluated with the area under the receiver operating characteristic curve (AUC) and internally validated using k-fold cross-validation. The pre-labor model was calibrated and a graphic nomogram and clinical impact curve were created. Results A total of 87.3% (884/1013) of women had successful VBAC, and 12.7% (129/1013) underwent unplanned cesarean delivery after a failed trial of labor. The AUC of the first-trimester model was 0.661 (95% confidence interval [CI]: 0.61–0.712), which increased to 0.758 (95% CI: 0.715–0.801) in the pre-labor model. The pre-labor model showed good internal validity, with AUC 0.743 (95% CI: 0.694–0.785), and was well calibrated. Conclusions VBAC provides women the chance to experience a vaginal delivery. Using a pre-labor model to predict successful VBAC is feasible and may help choose mode of birth and contribute to a reduction in cesarean delivery rate.

Abstract
BACKGROUND We aimed to develop and validate a nomogram for effective prediction of vaginal birth after cesarean (VBAC) and guide future clinical application. METHODS We retrospectively analyzed data from hospitalized pregnant women who underwent trial of labor after cesarean (TOLAC), at the Fujian Provincial Maternity and Children's Hospital, between October 2015 and October 2017. Briefly, we included singleton pregnant women, at a gestational age above 37 weeks who underwent a primary cesarean section, in the study. We then extracted their sociodemographic data and clinical characteristics, and randomly divided the samples into training and validation sets. We employed the least absolute shrinkage and selection operator (LASSO) regression to select variables and construct VBAC success rate in the training set. Thereafter, we validated the nomogram using the concordance index (C-index), decision curve analysis (DCA), and calibration curves. Finally, we adopted the Grobman's model to perform comparisons with published VBAC prediction models. RESULTS Among the 708 pregnant women included according to inclusion criteria, 586 (82.77%) patients were successfully for VBAC. Multivariate logistic regression models revealed that maternal height (OR, 1.11; 95% CI, 1.04 to 1.19), maternal BMI at delivery (OR, 0.89; 95% CI, 0.79 to 1.00), fundal height (OR, 0.71; 95% CI, 0.58 to 0.88), cervix Bishop score (OR, 3.27; 95% CI, 2.49 to 4.45), maternal age at delivery (OR, 0.90; 95% CI, 0.82 to 0.98), gestational age (OR, 0.33; 95% CI, 0.17 to 0.62) and history of vaginal delivery (OR, 2.92; 95% CI, 1.42 to 6.48) were independently associated with successful VBAC. The constructed predictive model showed better discrimination than that from the Grobman's model in the validation series (c-index 0.906 VS 0.694, respectively). On the other hand, decision curve analysis revealed that the new model had better clinical net benefits than the Grobman's model. CONCLUSIONS VBAC will aid in reducing the rate of cesarean sections in China. In clinical practice, the TOLAC prediction model will help improve VBAC's success rate, owing to its contribution to reducing secondary cesarean section.

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..

Reasons for previous Cesarean deliveries impact a woman's independent decision of delivery mode and the success of trial of labor after Cesarean. BMC Pregnancy Childbirth 2020; 20:170. [PMID: 32204702 PMCID: PMC7092517 DOI: 10.1186/s12884-020-2833-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Accepted: 02/24/2020] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Cesarean delivery rates are increasing globally with almost half of them occurring due to a previous Cesarean delivery. A trial of labor after Cesarean (TOLAC) is considered a safe procedure, but most eligible women instead undergo Cesarean before 39 weeks of gestation. Lack of education about TOLAC is often associated with increased repeat Cesarean. To reveal the safety and feasibility of TOLAC, we conducted this observational, prospective study with women's independent decisions. We aimed to clarify the relationship between their chosen mode of delivery and the reason for their previous Cesarean. Additionally, we have tried to identify maternal and obstetric factors associated with failed TOLAC to improve its success rate. METHODS This was a prospective, observational study of 1086 pregnant women with at least one previous Cesarean delivery. Of these, 735 women met our TOLAC criteria (Table 1), and then, could choose TOLAC or repeat Cesarean after receiving detailed explanations regarding the risks and benefits of both procedures. The primary outcomes were the number of successful TOLAC procedures and 5-min Apgar scores < 7 for the trial of labor after Cesarean group and elective Cesarean group. We collected the maternal and neonatal data including the reasons of previous Cesarean. RESULTS In total, 64.1% of women chose TOLAC. The success rate was 91.3%. The uterine rupture rate was 0.6%. There were no significant differences in the rate of Apgar scores at 5 min < 7 between both groups. Histories of experience of labor in previous Cesarean delivery were observed in 30 and 50% of women who chose TOLAC and repeat Cesarean, respectively (p < 0.05). Factors related to failed TOLAC included ≥40 weeks of gestation (odds: 5.47, 95% CI: 2.55-11.70) and prelabor rupture of membranes (PROM) (odds: 4.47, 95% CI: 2.07-9.63). CONCLUSIONS TOLAC is a favorable delivery option for both mothers and neonates when women meet criteria and choose after receiving detailed explanations. Women who experience PROM or ≥ 40 weeks of gestation, their modes of delivery should be reconsulted.

Abstract
Over the past few decades, overweight and obesity have become a growing health problem of particular concern for women of reproductive age as obesity in pregnancy has been associated with increased risk of obstetric and neonatal complications. The objective of this study is to describe the incidence of obstetric and perinatal complications in relation to maternal body mass index (BMI) at the time prior to delivery within the Spanish Health System. For this purpose, a cross-sectional observational study was conducted aimed at women who have been mothers between 2013 and 2018 in Spain. Data were collected through an online survey of 42 items that was distributed through lactation associations and postpartum support groups. A total of 5871 women answered the survey, with a mean age of 33.9 years (SD = 4.26 years). In the data analysis, crude odds ratios (OR) and adjusted odds ratios (AOR) were calculated through a multivariate analysis. A linear relationship was observed between the highest BMI figures and the highest risk of cephalopelvic disproportion (AOR of 1.79 for obesity type III (95% CI: 1.06–3.02)), preeclampsia (AOR of 6.86 for obesity type III (3.01–15.40)), labor induction (AOR of 1.78 for obesity type III (95% CI: 1.16–2.74)), emergency C-section (AOR of 2.92 for obesity type III (95% CI: 1.68–5.08)), morbidity composite in childbirth (AOR of 3.64 for obesity type III (95% CI: 2.13–6.24)), and macrosomia (AOR of 6.06 for obesity type III (95% CI: 3.17–11.60)), as compared with women with normoweight. Women with a higher BMI are more likely to develop complications during childbirth and macrosomia.
