FREQUENCY OF VAGINAL BIRTH AFTER 1 C-SECTION

Objective: The objective of this study was to determine the frequency of vaginal birth after previous 1 C-section.

Study Design: Cross sectional study

Settings:                Study was conducted in Labour Ward of Department of Obstetrics and Gynaecology, Allied Hospital, Faisalabad during the period from July 2017 to December 2017.

Methodology: After taking approval from hospital ethical committee, the patients presenting in labour ward who fulfilled the inclusion criteria were enrolled in the study. The identity of patient was recorded and an informed consent was taken. Exclusion criteria were strictly followed. Patients were admitted in labour ward, thorough history was elicited as per the Performa regarding age, weight, parity, previous obstetric performance including number of vaginal deliveries prior to this pregnancy, indication for previous C-section, any antepartum complication in this pregnancy e.g. major degree placenta Previa. A detailed general, physical, systematic and obstetric examination was done. They were carefully monitored in intrapartum period for any sign of uterine rupture e.g. abnormal fetal heart rate patterns, severe abdominal pain if persisting between contractions, acute onset scar tenderness, abnormal vaginal bleeding, haematuria, maternal tachycardia, hypotension & shock. Progress of labour was monitored. All the information was recorded on proforma by myself and patients undergoing vaginal delivery after cesarean section was noted. 

Results: In this study, out of 100 cases, 73%(n=73) were between 20-30 years of age whereas 27%(n=27) were between 31-35 years of age, mean + sd was calculated as 28.18+4.86 years, frequency of vaginal delivery after 1 cesarean section was recorded in 66%(n=66).

Conclusion: We concluded that the frequency of vaginal delivery after 1 cesarean section is higher, however, complications following this delivery may be recorded in coming trials, which will further helpful while making decision of VBAC.
