70年代初期起,美国倾向于对既往剖宫产的病例行选择性阴道试产。大量文献也证实此种处理的安全性和成功率。如在分娩开始前能准确预测阴道试产能否成功,可进一步提高临床处理水平。本研究旨在确定产科各种特异性变量或变量的综合与试产成功或失败之间有无联系。 Since the early 1970s, the United States has tended to undergo selective vaginal trial of cases of previous cesarean delivery. A large number of documents also confirm the safety and success rate of this treatment. Such as vaginal delivery before pregnancy can accurately predict the success of the trial, can further improve the level of clinical treatment. The purpose of this study was to determine if there was a link between the combination of various specific variables or variables in obstetrics and the success or failure of pilot production.
