摘要 目的探讨下肢骨折患者围术期阿司匹林和低分子肝素的应用对凝血与纤溶系统的不同影响。方法选择276例下肢新鲜骨折患者随机分为4组:A组76例为阿司匹林组,B组76例为低分子肝素组,C组66例为阿司匹林加低分子肝素组;D组58例为对照组。分别于术前、术后24 h2、d4、d7、d采静脉血检测凝血酶-抗凝血酶III复合物(TAT)及D-二聚体(DD)。结果①4组患者术前TAT水平均高于正常,术后24h较术前显著升高,2d开始减少,7d下降至术前水平。术后2d4、d B组、C组分别与A组、D组比较,差异均有统计学意义(P<0.05);②4组患者术前DD水平在正常范围,术后24h DD水平升高,2d开始减少,7d下降至术前水平。术后2d、4d B组、C组分别与A组、D组比较,差异均有统计学意义(P<0.05);③深静脉血栓形成(DVT)发生率A组与B组、B组与D组比较,差异有统计学意义(P<0.01);④回归分析术后DD的变化与性别、年龄、手术部位无关,与手术时间呈正相关(r=0.539,P=0.003)。结论单纯给予阿司匹林干预不能有效预防血栓形成,低分子肝素应用可影响凝血及纤溶系统,显著降低DVT发生率,预防血栓并发症安全有效。
