Objective To investigate a method which can foresee the success of delivery in pregnancy after previous cesarean and avoid maternal and infant complications. Methods Research objects were 292 cases of pregnant women who were pregnant after previous cesarean and with suitable natural-delivery conditions. The standard for evaluating and scoring was determined. Then the success rate of vaginal delivery and mother and infant outcomes of each score segment were observed. Results The success rate of vaginal delivery in cases with more than 80 points was 97. 31% , it was 55.06% in cases with 70-80 points, and it was 17. 65% in cases with less than 70 points. For cases with more than 80 points, the success rate of vaginal delivery was obviously higher than that of cesarean section rate (χ2= 6. 46, P < 0.01 ), while for cases with less than 70 points the cesarean section rate was significantly higher(χ2 =5. 19,P<0.01 ). No maternal and infant complications occurred. Conclusion The success rate can be timely and accurately judged for the cases with suitable natural-delivery conditions in pregnancy after previous cesarean when the score is strictly evaluated, and the delivery pattern should be chosen decidedly to avoid mother and infant complications induced by uterus rapture.%目的 探讨一种能够预见剖宫产术后再次妊娠经阴分娩成功,避免发生母婴并发症的方法.方法 以剖宫产术后再次妊娠符合试产条件的292例孕妇作为研究对象,确定评分标准,制定分值,观察各分值之间的阴道分娩成功率和母婴结局.结果 80分以上者阴道分娩成功率为97.31%,70～80分成功率为55.06%,70分以下成功率为17.65%.80分以上者阴道分娩成功率明显高于剖宫产率(χ2=6.46,P<0.01);70分以下者再次剖宫产率明显高于阴道分娩率(χ2=5.19,P<0.01).无母婴并发症发生病例.结论 剖宫产术后再次妊娠符合试产条件者在严格评分下可及时准确的判断成功率,果断地抉择分娩方式,避免子宫破裂引发的母婴并发症.
