对74名足月妊娠需引产的初产妇进行随机分组对照研究.实验组37例用蓖麻油乳引产、对照组37例用催产素静脉点滴引产,两组的一般情况无差异.蓖麻油乳引产的总有效率为30/37(81.1%),催产素组的总有效率为24/37(64.9%)。两组无差异.用药至规律宫缩时间及用药至分娩时间,蓖麻油乳组为39.19±36.27及49.03±37.27 h,对照组为13.39±18.62及21.51±20.13 h,两组差异非常显著(P<0.01).结论为:蓖麻油乳引产的效果与催产素相同,但起效慢,作用持续时间也长。
A total of 74 preterm infants who needed induction of labor during term pregnancy were randomly divided into control group, 37 patients in experiment group were induced by castor oil emulsion, 37 patients in control group were induced by intravenous injection of oxytocin, there was no difference in general condition between the two groups. The total effective rate was 30/37 (81.1%) and the total effective rate was 24/37 (64.9%) in the oxytocin group. There was no difference between the two groups.The time from administration to regular contractions and delivery to delivery were 39.19 ± 36.27 and 49.03 ± 37.27 h in the castor oil emulsion group and 13.39 ± 18.62 and 21.51 ± 20.13 h in the control group, respectively (P <0.01) .The conclusion is that the effect of induced labor of castor oil milk is the same as that of oxytocin, but the effect is slow and the duration of action is also long.
