摘要
目的探讨氨甲环酸(TXA)不同给药途径(局部、静脉以及局部静脉联合)减少初次膝关节置换术后出血量方面的安全性及有效性。方法选取2015年9月至2017年12月在西安交通大学第二附属医院骨一科因重度骨关节炎初次行单侧全膝关节置换术、无TXA使用禁忌的患者共计159例;排除术前存在深静脉血栓DVT、凝血功能异常、术前正使用抗凝药物、术前血红蛋白<100 g/L、伴有恶性肿瘤、伴有或曾发生心肌梗死和脑梗死的患者、伴有出血性疾病者、严重肝肾功能不全者。分为A、B、C、D 4组,A组给予关节腔注射生理盐水100 ml,B组给予关节腔注射氨甲环酸1 g,C组术前30 min给予静脉滴注氨甲环酸1 g,D组术前30 min静脉滴注氨甲环酸1 g+关闭关节囊后关节腔注射氨甲环酸1 g。记录患者术后凝血系列、显性失血量,并计算隐性失血量、总失血量、深静脉血栓发生率和输血率。计数资料使用2检验,组间相关测量指标比较使用方差分析。结果术前、术后1 d、3 d和7 d,同一时间点比较各组患者的凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)和纤维蛋白原含量无明显差异。4组术后深静脉血栓的发生率分别为10. 53%、11. 11%、13. 64%和13. 51%,差异无统计学意义(2=0. 961,P> 0. 05)。B组、C组和D组的显性失血量、隐性失血量和总失血量都明显低于A组(P <0. 05),D组的显性失血量和总失血量明显低于B组和C组(P <0. 05),而B组和C组的显性失血量、隐性失血量和总失血量均无明显差异(P> 0. 05)。A、B、C、D 4组的输血率分别为21. 05%,6. 67%、4. 76%和2. 94%,B组、C组和D组的输血率明显低于A组(χ~2=9. 914,P <0. 05)。结论氨甲环酸局部应用、静脉滴注以及二者联合应用均能有效减少全膝关节置换术后患者的失血量并降低输血率,而不增加术后深静脉血栓的发生率。静脉联合关节腔注射减少术后失血量的效果优于单独使用。
Objective To investigate the efficacy and safety of different administration route of tranexamic acid(TXA,topical,intravenous and combined applications)to reduce blood loss of primary total knee arthroplasty(TKA).Methods A total of 159 patients undergoing unilateral TKA from September 2015 to December 2017 were randomly divided into four groups.In group A,100 ml saline was injected into the articular cavity;in group B,1 g TXA was injected into the articular cavity;in group C,1g TXA was intravenously given 30 min before the operation;in group D,1g TXA was intravenously given 30 min before the operation and 1 g TXA was injected into the articular cavity after closing the joint capsule.Clotting series and external blood loss were recorded,and hidden blood loss,total blood loss,incidence of deep vein thrombosis(DVT)and the rate of blood transfusion were calculated.Measurement data was analyzed using one-way ANOVA,and calculator information was analyzed using chi-square test.Results The PT,APTT and fibrinogen content before the operation and 1d,3d and 7d after the operation showed no significant difference among different groups(P>0.05).In group A,B,C and D,the incidence of postoperative DVT were 10.53%,11.11%,13.64%and 10.53%,respectively,and no statistical significance was found(2=0.961,P>0.05).The external blood loss,hidden blood loss and total blood loss of group B,C and D were significantly lower than those of group A(P<0.05);the external blood loss and total blood loss of group D were lower than those of group B and group C(P<0.05);but the external blood loss,hidden blood loss and total blood loss displayed no obvious difference between group B and group C(P>0.05).In group A,B,C and D,the transfusion rate were 21.05%,6.67%,4.76%和2.94%respectively.The transfusion rates of group B,C and D were apparently lower than that of group A(2=9.914,P<0.05).Conclusion Topical intravenous and combined applications of TXA could all effectively reduce blood loss and decrease the rate of blood transfusion of TKA,showing no increase of the incidence of DVT;while combined application is more effective in reducing blood loss than other methods of drug administration.
