Outcome of the vaginal birth after cesarean section during the second birth order in West Kazakhstan

Predictors of successful trial of labor after cesarean section (TOLAC) in women with one prior transverse cesarean section at Tertiary Hospitals in northwest Ethiopia: a multicenter study

BACKGROUND

Trials of labor after cesarean section is the preferred strategy to decrease the cesarean delivery rate and reducing complications associated with multiple cesarean sections. The success rate of trials of labor after cesarean section and associated factors have not been well documented in Ethiopia. Hence, this study was aimed to determine the success rate and factors associated with the trial of labor after one cesarean section in five Comprehensive Specialized Hospitals located in northwest Ethiopia.

METHODS

An institutional-based cross-sectional study was conducted among 437 women who came for the trial of labor from December 1, 2021, to March 30, 2022. All women who fulfilled the eligibility criteria were included to this study. Data was collected using structured and pre-tested questionnaire. Then, the data was entered into Epi Data 4.6 software and exported to SPSS version 26 for analysis. To identify the variables influencing the outcome variable, bivariable and multivariable logistic regression analyses were conducted. The model's fitness was checked using the Hosmer-Lemeshow goodness of fit test, and an adjusted odds ratio with a 95% confidence interval was used to declare the predictors that are significantly associated with TOLAC.

RESULTS

The success rate of the trial of labor after one cesarean section was 56.3% (95% CI, 51.3%, 61.2%). Maternal age ≥ 35 years (AOR: 3.3, 95% CI 1.2, 9.3), the fetal station at admission ≤ zero (AOR: 5. 6, 95% CI 3.3, 9.5), vaginal delivery before cesarean section (AOR: 1.9, 95% CI 1.2, 3.2), and successful vaginal birth after cesarean delivery (AOR 2.2, 95% CI 1.2, 4.1) were found to have a significant association with the success rate of trial of labor after cesarean section.

CONCLUSIONS

In this study, the success rate of the trial of labor after a cesarean section was low as compared to the ACOG guideline and other studies in different countries. Therefore, the clinicians ought to offer counsel during antenatal and intrapartum period, encourage the women to make informed decision on the mode of delivery, and the practitioners need to follow fetal and maternal conditions strictly to minimize adverse birth outcomes.

Routine haemoglobin assay after uncomplicated caesarean sections

Introduction

This study designed to detect whether the routine haemoglobin (Hb) assay after uncomplicated caesarean section (CS) is necessary.

Material and methods

One hundred and twenty-two (122) women who delivered by uncomplicated elective CS were included in this observational study. Pre-operative investigations were performed according to the hospital protocol, including complete blood count, haemoglobin, prothrombin time, activated partial thromboplastin time, and liver and kidney function tests. After the uncomplicated elective CS, blood samples taken from participants immediately, 12, 24, 48 hours, and 1-week post-operative (PO) for haemoglobin assay. Student’s t-test was used to compare the pre-operative, and PO haemoglobins to detect whether or not the Hb assay after uncomplicated CSs is necessary.

Results

There was no significant difference between the pre-operative haemoglobin (11.6 ± 6.4 gms%), and the immediate PO haemoglobin (11.1 ± 5.9; p = 0.1 [95% CI: –1.05, 0.5, 2.05]) or 12-hour PO haemoglobin (10.9 ± 7.3; p = 0.9 [95% CI: –1.03, 0.7, 2.43]) or 24-hour PO haemoglobin (10.7 ± 8.2; p = 0.9 [95% CI: –0.95, 0.9, 2.75]). In addition, there was no significant difference between the pre-operative haemoglobin (11.6 ± 6.4 gms%), and 48-hour PO haemoglobin (11.2 ± 6.9; p = 0.7 [95% CI: –1.28, 0.4, 2.08]), or 1-week PO haemoglobin (11.4 ± 7.5; p = 0.9 [95% CI: –1.55, 0.2, 1.95]).

Conclusions

Routine PO haemoglobin assay after uncomplicated elective CSs is not necessary, especially when the pre-operative haemoglobin before the ECS ≥ 11 gms%, CS duration < 45 min, and estimated intra-operative blood loss ≤ 500 mL.

The Failure Rate, Related Factors, and Neonate Complications of Vaginal Delivery after Cesarean Section

Background

The rate of Cesarean Section (CS) is high in Iran. A successful Vaginal Birth After Cesarean (VBAC) section can protect mothers against the risk of having multiple CS. This study aimed to evaluate the success rate of VBAC, related factors, and the causes of failure.

Materials and Methods

This cross-sectional study was conducted on 150 pregnant women who were candidates for VBAC and admitted at maternity hospitals in Qom from 2016 to 2018. The required data were collected from the patients' records and entered into the checklist. Then, the success rate of VBAC was estimated, and related factors together with the causes of failure were determined by t-test, Chi-square, and independent-samples t-tests in SPSS v. 18 software.

Results

The mean (SD) maternal age was 32 (5.20) years and ranged from 21 to 45 years old. The success rate of VBAC was estimated to be 85.33%, and 14.67% of the patients had to repeat a CS after failure in vaginal delivery. The mean time between previous CS and present delivery was statistically significant between successful and failure groups (t ₁₂₅ = 2.32, p = 0.002). The results also revealed that the most important causes of VBAC failure were prolonged labor [odds ratio (OR) = 4.70)], full arrest (OR = 2.70), and decline fetal heart (OR = 5.31).

Conclusions

The success rate of VBAC in our study was high. However, VBAC was more successful when the interval between inter-deliveries was long, and lower complications were reported when the interval was 2-4 years.
