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. |
