本文通过研究脐静脉注射催产素对第三产程的影响,探讨其对产后出血的顶防作用.对象及方法77例孕妇均系足月、单胎、顺产,产前均未虚用催产素,随机分为 A,B, C三组.A 组26例,胎儿娩出I后1分钟内于脐静脉内注射生理盐水20ml;B 组26例,胎儿娩出后1分钟内于脐静脉注射生理盐水19ml 及催产素10U;C 组25例,胎儿娩出后1分钟内于母体肘静脉注射生理盐水19ml 及催产素10U.三组病人年龄(24～31岁)、孕周(38～41周)及胎儿体重(3000～3850g)无显著性差异.结果脐静脉注射催产素组第三产程时间及产后出血量均明显低于脐静脉注射生理盐水组(P 均<0.001),但与母体静脉注射催产素组无显著性差异(p>0.05)
In this paper, the study of umbilical vein oxytocin on the impact of the third stage of labor, to explore its role in the prevention and treatment of postpartum hemorrhage.Methods 77 pregnant women were full-term, single birth, A group were randomly divided into A, B, C three groups.A group of 26 cases, the fetus within 1 minute after I was injected intravenously in the umbilical vein saline 20ml; B group 26 cases, within 1 minute after delivery of fetal umbilical vein injection of normal saline 19ml And oxytocin 10U; Group C 25 cases, 1 minute after delivery of the fetus in the elbow vein injection of 19 ml saline and oxytocin 10U.All patients age (24 to 31 years), gestational age (38 to 41 weeks) and fetus Body weight (3000 ~ 3850g) .Results Umbilical intravenous oxytocin in the third stage of labor time and postpartum hemorrhage were significantly lower than the umbilical vein injection of saline (P <0.001), but with the mother intravenous oxytocin Group no significant difference (p> 0.05)
