研究目的:

氨甲环酸与纤溶酶原或纤溶酶的赖氨酸结合促进凝血块的稳定和沉积,起到抗纤维蛋白溶解的作用,尖吻蝮蛇血凝酶通过将纤维蛋白原转化为纤维蛋白而止血,具有良好的促凝效果,两者的结合理论上能有效起到快速止血的作用。然而氨甲环酸和尖吻蝮蛇血凝酶的联合运用尚缺乏可靠的临床数据支持,联合运用是否能产生协同作用并起到良好止血效果,同时不干扰机体凝血相关指标、尤其在骨科长期卧床患者中不增加血栓事件等并发症的发生,需要更多临床的研究以支持推广应用。我们期望,通过本实验发现两种止血药物的联合应用在接受腰椎椎间融合手术和髋、膝关节置换的手术中所具有的确切疗效,达到止血及减少其他并发症的目的,为患者尽快痊愈提供保障,为患者康复带来福音。  

Objectives of Study:

Tranexamic acid combined with lysine of plasminogen or plasmin to promote the stability and deposition of clots, which acts to prevent fibrinolysis. Haemocoagulase agkistrodon converts fibrinogen to fibrin, which stops bleeding and has a good procoagulant effect. The combination of the two may play a role in rapid hemostasis. However, the combination of tranexamic acid and haemocoagulase agkistrodon is still lacking reliable clinical data support. Can it produce synergy and have a good hemostasis effect without disturbing the body's coagulation function? Can it not increase complications such as thrombotic events in patients with long-term bed rest in orthopedics? This requires more clinical research to validate. We hope that through the experiment, we can find that the combination of two hemostatic drugs has the exact curative effect in the operation of lumbar fusion surgery and hip & knee joint replacement. This study will look for the best way to stop bleeding and reduce other complications, and provide protection for patients to recover as soon as possible.

药物成份或治疗方案详述:

本研究拟招募我院住院患者,符合准入标准的常规出血量较大的骨科手术,主要包括腰椎单节段融合、髋膝关节置换的病例。将研究对象随机分配到生理盐水组、氨甲环酸组、尖吻蝮蛇血凝酶组及尖吻蝮蛇血凝酶和氨甲环酸联合应用组。每组药物用量为:生理盐水组于术前20min用生理盐水100ml静脉滴注;氨甲环酸组于术前20min静脉输注10mg/kg,之后1mg/kg/h持续泵注至手术结束;尖吻蝮蛇血凝酶组于术前20min静脉输注2U;联合应用组术前20min静脉输注2U尖吻蝮蛇血凝酶及10mg/kg氨甲环酸,之后氨甲环酸以1mg/kg持续泵注至手术结束,所有药物剂量和使用方式均在药物使用说明书范围内,安全可靠。 

Description for medicine or protocol of treatment in detail:

This study is intended to recruit inpatients in our hospital, with single-segment fusion of the lumbar spine, hip or knee replacement in accordance with the admission criteria. The subjects were randomly assigned to the saline group (NS), the tranexamic acid group (TXA), the haemocoagulase agkistrodon group (HCA), and the combination of the haemocoagulase agkistrodon and the tranexamic acid group (HCA&TXA). The dosage of each group was as follows: the NS received 100 ml of normal saline intravenously 20 minutes before the operation; the TXA received 10 mg/kg of tranexamic acid intravenously 20 minutes before the operation, and then continued pumping to the operation at 1 mg/kg/h. The HCA received 2U of haemocoagulase agkistrodon intravenously 20 minutes before the operation. The HCA&TXA, 2 U of haemocoagulase agkistrodon and 10 mg/kg of tranexamic acid were intravenously infused 20 min before surgery, and then tranexamic acid was continuously pumped at 1 mg/kg until the end of the operation. All drug dosages and methods of use are based on the drug instructions.
