Vaginal Birth after Cesarean Delivery : Development of a Scoring System for Predicting Success Rate

Abstract


OBJECTIVE
To develop a scoring system to predict the likelihood of vaginal birth in patients undergoing a trial of labor after previous cesarean delivery.
METHODS
Variables influencing successful vaginal delivery rate were studied in 321 patients who had undergone a trial of labor after previous cesarean delivery from January, 1996 to December, 1998.
RESULTS
Totally, It resulted in a rate of vaginal birth after cesarean delivery of 70.1%. Six variables [maternal height, current fetal weight, prior vaginal delivery, indication for prior cesarean delivery, cervix dilatation in admission, head fixation] significantly affected a rate of successful vaginal birth after cesarean. Rate of successful vaginal birth after cesarean delivery was 27.5% in patients scoring less than or equal to 1, 95.1% in patients scoring greater than or equal to 4. Increasing score was associated with increasing vaginal delivery success rates.
CONCLUSION
It is expected that the proposed scoring system will be helpful for perspective patients and doctors deciding mode of delivery.
