新式旋转胎头法对降低母婴损伤的影响

Influence of new method of rotating fetus head on reducing the maternal and fetal injury

目的:探讨新式旋转胎头法对降低母婴损伤的效果。方法:将600例胎头位置异常拟经阴道分娩的初产、单胎产妇分为三组。观察组200例,用新式旋转胎头法,对照Ⅰ组200例,用苏氏旋转胎头法,对照Ⅱ组200例,用汪氏旋转胎头法纠正胎头位置异常。对比三组转位成败、产程、新生儿产瘤、血肿、产妇软产道的血肿、裂伤情况。结果:观察组转位成功率均高于对照Ⅰ、Ⅱ组(P<0.01),第一、二产程均短于对照Ⅰ、Ⅱ组(P<0.01),新生儿产瘤、血肿发生率均低于对照Ⅰ、Ⅱ组(P<0.01),产妇软产道损伤发生率均低于对照Ⅰ、Ⅱ组(P<0.01,P<0.05)。结论:用新式旋转胎头法纠正胎头位置异常转位成功率高,对降低阴道分娩中母婴损伤有效,值得临床推广应用。

Objective： To explore the effect of the new method of rotating fetus head on reducing maternal and fetal injury. Methods： Six hundred parturient primiparae who would bear a child by vaginal delivery were divided into observation group, control group A and control group B （ 200 cases for each group ）. The parturient primiparae were all pregnant with singleton pregnancy and all fetal heads were in abnormal position. The new rotating method was adopted in observation group, Su＇s method was used in control group A and Wang＇s method was applied in control group B, correcting abnormal position of fetal head. Comparison was made in the results of rotating, labor course, caput succedaneum and hematoma of neonate, laceration and hematoma of the soft birth canal among the three groups. Results： The translocation success rate were higher in observation group than that in control group A and B （ P 〈 0. 01 ） ; the first and second course of labor were shorter in observation group than that in control group A and B （P 〈0. 01 ） ; the incidence of caput succedaneum and hematoma of neonate were lower in observation group than that in control group A and B （ P 〈 0. 01 ） ; the rate of maternal soft birth canal injury was lower in observation group than that in control group A and B （ P 〈 0. 01, P 〈 0. 05 ）. Conclusion ： New rotating method can increase the success rate of transposition in correcting abnormal position of fetal head, which can effectively reduce maternal and fetal injury. The technique is recommended to be used in clinic.
