改良B-Lynch预防剖宫产术后出血的临床观察

Explore the prevention of postpartum hemorrhage in cesarean section-39 clinical cases

目的:探讨改良B-Lynch缝合术法预防选择性剖宫产出血的临床效果。方法:将2004年1～12月有发生产后出血危险因素的剖宫产孕妇随机分为观察组39例与对照组42例,两组术中均使用缩宫素药物,观察组术中行改良B-Lynch缝合术。结果:观察组术毕阴道积血量及术后2h累计出血量显著少于对照组(P<0.05),24h产后出血发生率低于对照组(P<0.05)。产后出血率两组比较有显著性差异(χ2=19.78,P<0.01)。结论:剖宫产术中行改良B-Lynch缝合术能有效预防剖宫产术后出血,降低产后出血发生率。

Objective： Explore the effect of improved B - Lynch sutura to prevent postpartum hemorrhage in cesarean section. Methods： Cesarean section gravidas with haemorrhage risk factor were selected during January to December in 2004, and divided into observed （ 39 cases） and controlled group （ 42 cases） randomly, they all used oxytocin drugs in operation and the observed group opera- ted improved B - Lynch sutura. Results： Hematocolpos and haemorrhage of post - operation in 2 h and in 24 h in observed group is much lower than the controls （ P 〈 0. 05, P 〈 0. 05 ）, and postpartum hemorrhage rate is also lower than the control （χ^2 = 19. 78, P 〈 0. 05 ） . Conclusion： Improved B - Lynch sutura can prevent postpartum hemorrhage in cesarean section and decsrease postpartum hemorrhage rate effectively.
