Frequency of uterine rupture after one successful vaginal birth after cesarean section (VBAC).

Abstract

Objectives: To determine the frequency of uterine rupture after one successful vaginal birth after caesarean section. Study Design: Cross Sectional Study. Setting: Department of Obstetrics and Gynecology of Nishtar Hospital Multan. Period: From12-May-2017 to 11-May-2018. Material & Methods: Total number of 135 patients of 16-45 years with singleton pregnancies were admitted for 2^nd Vagina Birth after cesarean Section at gestational age ≥ 28 weeks of gestation. Data in shape of parity, gestational age and BMI was taken. These patients were assessed for frequency of uterine rupture after one successful vaginal birth after caesarean section. Data was analyzed with statistical analysis program (SPSS version 21). Frequency and percentage was calculated for qualitative variables like parity and uterine rupture. Mean ± SD was calculated for quantitative variables like age, BMI and gestational age. Results: Mean age of patients was 29.88+5.34 years. Mean body mass index (BMI) of study patients was 25.17+4.88 kg/m². Mean gestational age at the time of delivery was 39.01+2.54 weeks. Uterine rupture after vaginal birth occurred in 2 (1.48%) patients. There was no association of gestational age, parity and gestational age with the frequency of uterine rupture. Conclusion: Women with prior successful VBAC are at low risk of maternal and neonatal complications during subsequent trail of VBAC with lower risk of uterine rupture and perinatal complications.
