400例产后出血患者的危险因素分析及其对应防治方法的临床研究

目的探讨影响剖宫产术后出血的危险因素及研究其对应的防治方法。方法对400例产后出血患者的临床资料进行回顾性分析,记录患者出血原因、分娩方式、分娩史、妊娠并发症等基本资料,进行统计学分析。结果产后出血原因对比中,子宫收缩乏力占74.5%(χ2=249.4,P<0.05);分娩方式对比中,剖宫产占64.5%(χ2=11.1,P<0.05);分娩史对比中,初产占77.0%(χ2=37.7,P<0.05);妊娠并发症对比中,有妊娠并发症占80.0%(χ2=46.8,P<0.05),其余项差异无统计学意义(P>0.05)。结论子宫收缩乏力、剖宫产、初产、有妊娠并发症为影响产后出血的独立危险因素,因此可据情处理。

Analysis of risk factors and clinical study of prevention and control methods for 400 cases with postpartum hemorrhage

Objective To investigate risk factors and prevention or control methods for postpartum hemor- rhage after childbirth. Methods The clinical data of 400 cases with postpartum hemorrhage were retrospectively ana- lyzed, and recording causes of bleeding in patients, the mode of delivery, birth history, pregnancy complications, which basic information was statistically analyzed. Results For the reasons of postpartum hemorrhage bleeding,uterine ato- ny was 74.5%（X^2 =249.4,P〈0.05） ;mode of delivery contrast,cesarean section was 64.5%（X^2 = 11. 1,P〈0.05） ; birth history contrast, early production was 77. 0%（X^2=37. 7, P〈0. 05 ） ; comparison of pregnancy complication, pregnancy complications was 80.0% （ X^2 =46.8, P〈0.05 ）, the rest items had no difference（ P〉0.05 ）. Conclusion Binary logistic regression analysis showed that uterine inertia,cesarean section, primiparity were pregnancy complica- tions independent risk factors of postpartum hemorrhage,which can be treated according to the situation.
