第三产程过长与产后出血罹患率及治疗干预包括清宫术和人工剥离胎盘术的增加有关。1983年Golan 等报道一种处理胎盘滞留术的新方法,对10名第三产程超过30分钟的产妇,经胎盘脐静脉注射催产素10U+生理盐水20ml,后5分钟内胎盘娩出。因无对照组,故脐带内注射催产素的效应未证实。作者假想,如脐带内注射催产素对治疗胎盘滞留有效,则其机理涉及催产素从绒毛血管渗透到绒
Excessive third-stage labor and postpartum hemorrhage rates and treatment interventions include curettage and manual dissection of placenta accreta. 1983 Golan et al reported a new method of treatment of placenta accreta, 10 of the third stage of labor more than 30 minutes of women, umbilical vein through the placenta 10U + saline injection 20ml, within 5 minutes after the placenta was delivered. The effect of oxytocin in the umbilical cord was not confirmed because of no control group. The authors hypothesize that if umbilical cord oxytocin is effective for retention in the treatment of the placenta, the mechanism involves oxytocin infiltration from the villus into the velve
