目的:评价低分子肝素在重症监护室长期卧床患者中应用的临床疗效。方法采用前瞻性研究方法,将46例长期卧床患者随机分组为低分子肝素组和对照组,两组均给予间歇压力充气泵下肢运动疗法,低分子肝素组另外给予低分子肝素钙抗凝。在此过程中收集并观察两组患者的临床资料,探讨低分子肝素对预防重症监护室长期卧床患者的深静脉血栓(DVT)发生率及肺栓塞发生的影响。结果低分子肝素组下肢深静脉血栓发生率、D-D 二聚体数值及氧合指数等方面与对照组比较差异均有统计学意义,而且两组患者在肺动脉高压发生率方面比较差异亦有统计学意义(P ﹤0.05),血小板及 PT 等影响出血指标两组比较差异无统计学意义。结论低分子肝素可显著降低重症监护室长期卧床患者的 DVT 发生率,进而可降低肺栓塞发生率,且安全有效。
