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.
