不同分娩方式与孕妇分娩后出血量的相关性研究

Study on the Correlation Between the Different Mode of Delivery and Amount of Bleeding After Delivery in Pregnant Women

目的探讨不同分娩方式与孕妇分娩后出血量的相关性。方法随机选取2010年1月至2012年12月我院妇产科住院治疗的300例足月产孕妇作为观察对象,其中自然分娩150例,设为对照组,剖宫产150例,设为实验组,观察两组产妇分娩后出血情况,并且探讨相关影响因素。结果实验组出血率为27.3%,高于对照组的9.3%(P<0.05);宫缩乏力、软产道损伤、胎盘因素、血窦开放伴血管损伤是分娩后出血的常见影响因素,其中观察组宫缩乏力和血窦开放伴血管损伤例数明显多于对照组(P<0.05)。结论剖宫产较自然分娩更容易发生产后出血,并且出血量较多,临床上应严格把握适应症,尽量选择自然分娩。

Objective To investigate the relationship between the different mode of delivery and the amount of bleeding after delivery of pregnant women. Methods Three hundred full-term pregnant women from January 2010 to December 2012 in our hospital were selected as research objects, included 150 cases of natural childbirth, set as control group, and 150 cases of cesarean section, set as experimental group. The situation of bleeding after delivery was observed in two groups, and the related factors were discussed. Results The hemorrhage rate was 27.3% of experimental group, significantly higher than 9.3% of control group （P〈0.05）. Uterine inertia, placenta factor, injury of soft birth canal, blood sinus with vascular injury were the common factors which influenced postpartum hemorrhage; The observation group had more cases of uterine inertia and sinus open with vascular injury comapred with the control group （P 〈0.05）. Conclusions Postpartum hemorrhage is more likely to happen in cesarean section than natural childbirth, and amount of bleeding is more too. We should strictly master the clinical indications and choose natural childbirth as much as possible.
