A program of trial labor by patients who had previously undergone one low cervical transverse cesarean section is described. Experience with 526 such patients shows that 49% delivered vaginally, doing so with slightly less morbidity and a shorter hospital stay than 108 similar patients not given a trial labor. Perinatal mortality and morbidity were unaffected by trial or route of delivery. Uterine rupture was encountered three times in the trial group and once in the nontrial patients but at no time resulted in a serious threat to the mother or child. Fertility was retained in 2 of the 4 patients. A significant increase in maternal morbidity was noted among patients whose trial labor resulted in a repeat cesarean section.
本文描述了一项针对曾接受过一次低位子宫横切口剖宫产手术患者的试产计划。对526例此类患者的经验显示，49%的患者经阴道分娩，与108例未进行试产的类似患者相比，其发病率略低，住院时间更短。围产期死亡率和发病率不受试产或分娩途径的影响。试验组发生子宫破裂3次，非试验组患者发生1次，但均未对母婴造成严重威胁。4例患者中有2例保留了生育能力。试产导致再次剖宫产的患者中，产妇发病率显著增加。
