The Application of Tourniquet in Dangerous type of placenta previa

目的:探讨止血带环套子宫下段暂时性压迫止血,在凶险型前置胎盘中应用的临床疗效。方法:对某市妇幼保健院因凶险型前置胎盘行剖宫产术的患者共46例,其中23例患者术中采用止血带为观察组,另23例未采用止血带为对照组。结果:观察组在出血量、血色素变化、子宫切除率、手术时间、感染率均优于对照组,两组差异有统计学意义(P<0.05)。结论:在凶险型前置胎盘剖宫产手术中止血带环套子宫下段暂时性压迫止血,能明显为手术赢得宝贵的抢救时间,明显减少产后出血量、子宫切除率及感染率,术后血色素无明显变化。

Objective： to explore the clinical application of tourniquet for temporary hemostasis by ring setting the lower uterine segment in dangerous type of placenta previa. Method： Among 46 cases of patients undergoing cesarean section due to dangerous type of placenta previa in certain maternal and children＇s heahhcare hospital, 23 patients using tourniquet belong to observation group, 23 cases without tourniquet belong to control group. Result： Bleeding amount, hemoglobin change, rate of hysterectomy, surgery time, infectious rate of observation group are much better than those of the control group. There is sinificant difference （P〈0.05）. Conclusion： Application of tourniquet for termporary hemostasis by ring setting the lower uterine segment in dangerous type of placenta previa can sinificantly win rescue time for surgery, reduce bleeding, rate of hysterectomy and infectious rate. There is evident change in hemoglobin.
