产后出血相关因素分析

The analysis on related factors of postpartum hemorrhage

目的分析近8年产后出血发病率及其相关因素,探讨减少产后出血合理的防治措施。方法回顾性分析2001～2008年住院分娩患者产后出血539例的临床资料。结果8年间产后出血发生率为2.69%,经产妇产后出血发生率明显高于初产妇,两者比较差异有统计学意义(P<0.01),剖宫产出血率高于阴道分娩,两者比较也有统计学意义(P<0.01)。产后出血原因以宫缩乏力,胎盘因素多见,分别占56.40%和32.47%,后4年与前4年相比,胎盘因素所致出血率增高,且差异有统计学意义(P<0.05)。结论降低产后出血率需从孕产妇自身保健和提高医务人员业务水平两方面着手,以减少产后出血发生率。

Objective To explore rational preventive measures on reducing postpartum hemorrhage through analyzing incidence rate and related factors of inpatients in the past 8 years. Methods Clinical data of 539 cases with postpartum hemorrhage was analyzed retrospectively. Results The incidence rate of postpartum hemorrhage was 2.69% in past 8 years which was significantly higher in multiparaes than that in nullipara （ P 〈 0.01 ）. It was also significantly higher in cesarean section cases than that in transvaginal cases （ P 〈 0. 01 ）. The main causes of postpartum hemorrhage were uterine atony and placental reasons and the rate was 56.40% and 32.47% respectively. The hemorrhage rate resulting from placental reasons from 2005 - year to 2008 - year was higher than that from 2001 - year to 2004 - year and the difference was significant （ P 〈 0. 05 ）. Conclusion To reduce the incidence of postpartum hemorrhage, measures should be taken to promote the maternal healthcare and medical staff＇s professional skills.
