347例足月妊娠阴道分娩的产妇随机分为三组:臀部肌内注射组、宫底肌内注射组及脐静脉注射缩宫素组,采用3种不同的方法来观察其对第三产程持续时间以及产后2h出血量的影响。结果臀部肌注组分别与脐静脉注射组和宫底肌内注射组的出血量比较,差异有统计学意义(P<0.05),脐静脉注射组与宫底肌内注射组的出血量比较,差异有统计学意义(P<0.05),臀部肌内注射组分别与脐静脉注射组和宫底肌内注射组的第三产程持续时间比较,差异有统计学意义(P<0.05),脐静脉注射组与宫底注射组第三产程持续时间比较,差异无统计学意义(P>0.05)。
347 pregnant women with vaginal delivery of term pregnancy were randomly divided into three groups: intramuscular injection of the buttocks, intramuscular injection of the uterus and oxytocin injection into the umbilical vein. Three different methods were used to observe the effect on the third stage of labor Time and 2h postpartum hemorrhage. Results Compared with the intramuscular injection group and intramuscular injection group, the amount of bleeding in intramuscular injection group was significantly lower than that in intramuscular injection group (P <0.05) (P <0.05). Compared with the duration of the third stage of labor in intramuscular injection group and intrauterine injection group, there was significant difference (P <0.05). The umbilical vein There was no significant difference in the duration of the third stage of labor between the injection group and the Uterine injection group (P> 0.05).
