Fifty-five patients with a history of two or more cesarean sections underwent a trial of labor. Forty-two had had previous uterine incisions of unknown type, 11 had had low cervical transverse incisions, and two had had low vertical incisions. Twenty-five women (45%) had successful vaginal deliveries, and 30 (55%) received oxytocin augmentation of labor. The incidence of vaginal delivery was significantly lower in patients who required oxytocin augmentation (30 versus 64%, P less than .01). Three of the 55 patients had scar separation detected at the time of delivery. Two patients underwent hysterectomy. There were no maternal or neonatal deaths. A history of multiple cesarean sections need not exclude the patient from the option of trial of labor.
55例有两次或更多次剖宫产史的患者接受了引产试验。42例既往子宫切口类型不明，11例为低位宫颈横切口，2例为低位纵切口。25名妇女（45%）成功经阴道分娩，30名（55%）接受了催产素引产。需要催产素引产的患者阴道分娩发生率显著较低（30%对64%，P<0.01）。55例患者中有3例在分娩时发现瘢痕分离。2例患者接受了子宫切除术。无孕产妇或新生儿死亡。多次剖宫产史不应排除患者进行引产的选择。
