间歇式充气压力治疗仪预防肺癌术后患者下肢深静脉血栓形成的研究

目的 探讨间歇式充气压力治疗仪预防肺癌术后患者下肢深静脉血栓形成（DVT）形成的治疗效果.方法 选取河北北方学院附属第一医院心胸外科120例肺癌患者,完全随机分成对照组与试验组,各60例.对照组给予传统护理方法;试验组给予传统护理方法＋间歇式充气压力治疗法.于术后第7天观察DVT特征性临床症状,术后4、7 d观察DVT发生率、血流动力学情况.结果 对照组有12例（20.0%）自诉肢体疼痛等不适,而试验组有3例（5.0%）自诉有肢体疼痛不适,2组DVT特征性临床症状比较差异有统计学意义（χ2=6.171,P〈0.05）;术后第4、7天,对照组DVT发生率分别为8.3%（5例）、11.7%（7例）,试验组DVT发生率分别为为0%、1.7%（1例）,对照组DVT发生率高于试验组（χ2=5.217,χ2=4.821,均P〈0.05）;术后第4、7天,试验组的股静脉血流速度（平均流速和峰值流速）明显好于对照组术后第4天：（15.2±2.9）cm/s比（14.3±3.1）cm/s,（20.5±4.0）cm/s比（19.5±4.2）cm/s;术后第 7天：（16.1±3.2）cm/s比（14.6±3.1）cm/s,（21.5±5.9）cm/s比（19.5±5.3）cm/s]（均P〈0.01）.结论 间歇式充气压力治疗仪在预防肺癌术后DVT,具有操作简便,使用安全、方便等优点.

Research of intermittent pneumatic pressure therapy preventing lung cancer with deep vein thrombosis

Objective To investigate the therapeutic effect of intermittent pneumatic pressure therapy on lung cancer with deep vein thrombosis （DVT） formation. Methods All 120 cases of lung cancer patients from cardiothoracic surgery in the first affiliated hospital of Hebei north university were randomly divided into the control group and the experimental group. The control group received traditional therapy; experimental group received traditional nursing combined with intermittent pneumatic pressure therapy. The incidence of DVT and hemodynamic situation in the fourth day and the seventh day after surgery were observed. Results The characteristic clinical symptoms of DVT in two groups was significantly different （P〈0.05）. On the fourth day and the seventh day after surgery, the incidences of DVT in the control group were 8.3%（5 cases） and 11.7%（7 cases）. The incidence of DVT in the control group was significantly higher than that in the experimental group （P〈0.05）; on the fourth day and the seventh day after surgery, the femoral vein blood flow velocity （average velocity and peak velocity） in experimental group was significantly better than that in the control group（15.2±2.9）cm/s vs （14.3±3.1）cm/s,（20.5±4.0）cm/s vs （19.5±4.2）cm/s;in the seventh day：（16.1±3.2）cm/s vs （14.6±3.1）cm/s,（21.5±5.9）cm/s vs （19.5±5.3）cm/s]（all P〈0.05）. Conclusion Intermittent pneumatic pressure therapy can prevent incidence of postoperative DVT in lung cancer.
