Vaginal birth after previous caesarean section in women at Al-Wahda hospital Derna, Libya

Background: Vaginal birth after caesarean section is one strategy that has been developed to decrease the rate of caesarean section.Methods: The prospective observational study was carried out over a period of 01 January 2017 to 31 December 2018 years. VBAC was routinely offered at Al-Wahda hospital Derna to women fulfilling the criteria for trial of scar, according to the hospital protocol.Results: A total of 5018 deliveries took place in the study duration, there were 1039 (20.7%) had previous one caesarean section, out of which 319 (30.7%) were the number of underwent repeat caesarean section and 720 (69.3%) were the number of VBAC. The indications for emergency repeat caesarean section at Al-Wahda hospital was (29.3%) malpresentation, (24.45%) FD, (13.47) postdate, (11.59) obstracted lab and abruptiopl (5.95%). Anemia and difficult intubation were observed in repeated caesarean section.Conclusions: This study concluded that there is a high chance of success in a trial of labor. These findings might help clinicians and women in the decision-making for the mode of delivery when it comes to pregnancy with a previous caesarean section. Women are explained about the option of trial of scar and told about the risk associated with a repeat CS, so many CSs can be avoided.

Birth after previous caesarean section

Midwifery and obstetric involvement in supported decision making and subsequent clinical practice around birth after caesarean section has been much debated and negotiated for some time. This article discusses some of the clinical evidence and factors to be taken into account when providing support and information for women and birthing people considering their options for birth after caesarean. The article focuses on the currently published guidelines to support practice and guide discussions with women and birthing people. In the article, the terms ‘planned vaginal birth’ and ‘vaginal birth after caesarean’ are used interchangeably.

Risk of obstetric anal sphincter injury among women who birth vaginally after a prior caesarean section: A state-wide cohort study

Objective: Vaginal birth after caesarean (VBAC) has been suggested to be associated with an increased risk of obstetric anal sphincter injury (compared with primiparous women who birth vaginally). However, prior studies have been small, or used outdated methodology. We set out to validate whether the risk of obstetric anal sphincter injury among women having their first VBAC is greater than that among primiparous women having a vaginal birth. Design: State-wide retrospective cohort study. Setting: Victoria, Australia. Population: All births (455,000) between 2009-2014. Methods: The risk of severe perineal injury between first vaginal birth and first vaginal birth after previous caesarean section was compared, after adjustment for potential confounding variables. Covariates were examined using logistic regression for categorical data and Wilcoxon rank-sum test for continuous data. Missing data were handled using multiple imputation; the analysis was performed using regression adjustment and Stata v16 multiple imputation and teffects suites. Results: Women having a VBAC (n=5,429) were significantly more likely than primiparous women (n=123,353) to sustain a 3rd or 4th degree tear during vaginal birth (7.1 vs 5.7%, p<0.001). After adjustment for mode of birth, body mass index, maternal age, infant birthweight, episiotomy and epidural, there was a 21% increased risk of severe perineal injury (relative risk 1.21 (95%CI 1.07 – 1.38)). Conclusions: Women having their first vaginal birth after caesarean section have a significant increased risk of sustaining a 3rd or 4th degree tear, compared with primiparous women having a vaginal birth. Patient counselling and professional guidelines should reflect this increased risk.

A comparison of antenatal prediction models for vaginal birth after caesarean section

ABSTRACT Introduction: An antenatal scoring system for vaginal birth after caesarean section (VBAC) categorises patients into a low or high probability of successful vaginal delivery. It enables counselling and preparation before labour starts. The current study aims to evaluate the role of Grobman nomogram and the Kalok scoring system in predicting VBAC success in Singapore. Methods: This is a retrospective study on patients of gestational age 37 weeks 0 day to 41 weeks 0 day who underwent a trial of labour after 1 caesarean section between September 2016 and September 2017 was conducted. Two scoring systems were used to predict VBAC success, a nomogram by Grobman et al. in 2007 and an additive model by Kalok et al. in 2017. Results: A total of 190 patients underwent a trial of labour after caesarean section, of which 103 (54.2%) were successful. The Kalok scoring system (AUC [area under the curve] 0.740) was a better predictive model than Grobman nomogram (AUC 0.664). Patient’s age odds ratio [OR] 0.915, 95% CI [confidence interval] 0.844–0.992), body mass index at booking (OR 0.902, 95% CI 0.845–0.962), and history of successful VBAC (OR 4.755, 95% CI 1.248–18.120) were important factors in predicting VBAC. Conclusion: Neither scoring system was perfect in predicting VBAC among local women. Further customisation of the scoring system to replace ethnicity with the 4 races of Singapore can be made to improve its sensitivity. The factors identified in this study serve as a foundation for developing a population-specific antenatal scoring system for Singapore women who wish to have a trial of VBAC.

Maternal and neonatal outcome in pregnancy with previous lower segment caesarean section undergoing trial of scar

Background: Women with previous LSCS often have to make a decision about mode of delivery of their second baby. As the rate of caesarean section is continuously increasing, vaginal birth after caesarean section (VBAC) is a good strategy to decrease caesarean rate. The present study was planned to assess the fetomaternal outcome in pregnancies with previous lower segment caesarean section undergoing trial of scar and to identify the factors, which can influence the outcome of trial of scar.Methods: This was a prospective observational study on 100 patients at a tertiary care institute. Pregnant women with previous LSCS were selected randomly for the study on the basis of the inclusion and exclusion criteria. Each labor monitored closely using a partogram. Decision for repeat emergency caesarean was taken by consultant. All women included in the study were followed through delivery and till discharge.Results: Out of 100 pregnant women 49 % cases had successful VBAC, 50% had emergency caesarean and one patient had laparotomy for rupture uterus. In women, who also had a prior vaginal delivery, 72% delivered vaginally, as compared to 40% of the women who did not undergo prior vaginal delivery (p value=0.003). Women who were in spontaneous labor, 59.21% delivered vaginally, whereas women who were induced, 16.6% delivered vaginally. The rate of perinatal complication was more in the patients who required an emergency CS after a failed trial. Conclusions: Our findings may encourage obstetricians to encourage VBAC in the properly screened ANC patients and decrease the rate of recommending caesarean section.
