摘要 目的探讨术中关节腔内注射氨甲环酸(TXA)在减少全膝关节置换术(TKA)后出血的疗效及安全性分析。方法选取符合纳入标准的患者50例,采用软件随机平均分为两组(试验组和对照组)。试验组于术后关节腔内注射20 mL溶有1.0 g氨甲环酸的生理盐水,术后夹闭引流管4 h后放开;对照组术后直接向关节腔注射生理盐水20 mL,同样夹闭引流管4 h后放开。主要观察指标包括显性失血量、输血率、术后复查血常规指标、术后并发症,次要观察指标包括美国特种外科医院(HSS)膝关节功能评分,并作统计学分析。结果试验组术后2 d总的引流量、输血人数及输血总量明显少于对照组,差异均有统计学意义(P<0.05);试验组术后血红蛋白浓度及红细胞比容高于对照组,差异有统计学意义(P<0.05);术后凝血功能、血栓发生率及术后不良事件发生率方面差异无统计学意义(P>0.05)。结论关节腔内注射氨甲环酸可有效减少全膝关节术后出血量、输血率,同时并不增加血栓发生风险。
