【摘要】 目的:系统评价患者血小板与冷沉淀联合输注在大出血临床治疗中的效果。方法:计算机检索中国生物医学文献数据库(CBM)、中国期刊全文数据库(CNKI)和万方数据库(Wanfang Date)。采用RevMan 5.3软件对15篇随机对照试验(RCTs)的1316例患者进行Meta分析。结果:与单用血小板相比,血小板与冷沉淀联合输注组的PT、APTT和平均止血时间均显著短(P<0.01),24 h内悬浮红细胞使用量显著少(P<0.01);止血有效率显著高(P<0.01),输血后的PLT无显著变化(P>0.05);与单用冷沉淀相比,血小板与冷沉淀联合输注组的PT、APTT和平均止血时间均显著短(P<0.01),24 h内悬浮红细胞使用量显著少(P<0.01),输血后的PLT和止血有效率显著高(P<0.01)。结论:血小板与冷沉淀联合输注有效纠正了大出血患者的凝血功能障碍,止血效果更为显著,为挽救患者的生命赢得了宝贵的时间。

【Abstract】 Objective:To systematically evaluate therapeutic effects of co-infusion of platelets and cryoprecipitation in the treatment of patients with massive blood loss.Method:The domestic lectures were retrieved from databases including CBM,CNKI,Wanfang Database.The meta-analyses were performed with RevMan 5.3 software for 15 randomized controlled trials(RCTs) of 1316 patients.Result:Compared with platelet group,PT,APTT and the average hemostasis time of co-infusion were all significantly shorten(P<0.01),the consumption of suspended red blood cells in 24 h was decreased significantly(P<0.01),and hemostatic efficiency was improved significantly(P<0.01),and post transfusion PLT had no significant changes(P>0.05).Compared with cryoprecipitation group,PT,APTT and the average hemostasis time of co-infusion were all significantly shorten(P<0.01),the consumption of suspended red blood cells in 24 h was decreased significantly(P<0.01),and hemostatic efficiency and post transfusion PLT were improved significantly(P<0.01).Conclusion:Co-infusion overcome the coagulation disorders in patients with massive blood loss,and it is the best method of hemostatic effect.It will win enough time for saving the patients precious life.

大出血是由内脏损伤、动脉破裂等引发的大量出血现象。患者在大出血过程中由于血小板和凝血因子的大量流失,极易引发凝血障碍等相关并发症,严重者可导致失血性休克甚至威胁生命安全[1]。目前,对单采血小板的需求基本处于供不应求的状态,同时大量输注库存血还会引起患者出现凝血功能异常等现象[2]。已有报道表明,大出血患者在红细胞制品输入时联合输注单采血小板和冷沉淀,可以及时补充血液中的凝血因子和血小板,改善各项凝血指标,有利于抢救的进行。因此,本文采用循证医学的原理及方法,系统评价了血小板与冷沉淀联合输注治疗急性大出血的随机对照试验(RCT),为临床大出血患者抢救方案的制定提供可靠依据。
