摘要 目的探讨氨甲环酸对全膝关节置换术围手术期失血量的影响。方法 2007年5月至2009年2月,选取92例拟行全膝关节置换术的患者,男34例,女58例;骨性关节炎62例,类风湿关节炎30例。病程2~10年,平均5年。随机分为A、B两组,每组46例。A组在膝关节假体安装后松止血带时,将氨甲环酸1 g稀释于250 m l生理盐水后静脉点滴,第一次给药3 h后以相同剂量再次给药;B组仅给予等量生理盐水静脉点滴。以术中失血量、术后可见失血量、输血量、输血人数、术后血红蛋白和术后纤维蛋白原、凝血酶原时间等为评价指标,对两组进行比较;观察患者术后是否出现下肢深静脉栓塞的临床症状,并于术后14 d进行下肢血管多普勒超声检查。结果术中失血量两组比较差异无统计学意义(P>0.05),但术后可见失血量、输血量、输血人数A组均明显少于B组(P<0.05);术后血红蛋白值,A组明显大于B组(P<0.05);两组患者术中松止血带和术后3 h纤维蛋白原、凝血酶原时间和活化部分凝血活酶时间的比较差异无统计学意义(P>0.05);术后14 d未发现下肢深静脉血栓形成。结论在全膝关节置换术中及术后短期使用氨甲环酸,能明显降低患者失血量及输血量,并且不增加静脉血栓形成的风险。
