We compared 60 twin pregnancies treated by bed rest, 37 treated by cervical suture and 36 receiving no active treatment. The incidence of the spontaneous onset of labour before 36 weeks of gestation, the mean gestational age at delivery, mean birth weights of the first and second twins and the incidence of 'small-for-dates babies' were similar in all three groups.
我们比较了60例接受卧床休息治疗的双胎妊娠、37例接受宫颈缝扎术治疗的双胎妊娠以及36例未接受积极治疗的双胎妊娠。三组中，妊娠36周前自然发动分娩的发生率、分娩时的平均孕周、第一和第二胎儿的平均出生体重以及“小于胎龄儿”的发生率相似。
