间歇充气加压预防重症患者下肢DVT效果研究

A study on the effect of intermittent pneumatic compression in the prevention of DVT of lower extremity in critically ill patients

目的：探讨间歇充气加压预防重症患者下肢深静脉血栓形成（DVT）的效果。方法：回顾2015年1~3月于我院重症医学科住院的258例患者资料,其中将应用分级加压弹力袜预防下肢DVT 120例作为对照组,将采用间歇式充气加压法预防下肢DVT 138例作为观察组。比较两组干预前及干预后第2、5、7天股静脉血流峰速度（Vp）、血流平均速度（Vm）和血流量（BF）及下肢DVT和肺栓塞发生情况。结果：观察组干预后第5天和第7天股静脉Vp、Vm、BF均高于对照组（P〈0.01）;观察组下肢DVT发生率低于对照组（P〈0.05）。结论：间歇充气加压可促进下肢血液循环,有效预防重症患者下肢DVT,效果优于分级加压弹力袜。

Objective： To investigate the effect of intermittent pneumatic compression in the prevention of deep vein thrombosis（ DVT）of lower extremity in critically ill patients. Methods： The data of 258 hospitalized critically ill patients in our hospital were retrospectively analyzed. 120 critically ill patients treated with the graded compression elastic stockings were taken as the control group; the other 138 patients treated with intermittent pneumatic compression for the prevention of DVT were taken as the observation group. The Vp,Vm and BF of femoral vein and the incidence of DVT and pulmonary embolism were compared between the two groups before the intervention and on the 2nd,5th and 7th day after the intervention. Results： The Vp,Vm and BF of femoral vein on 5th and 7th day after the intervention were higher in the observation group than those in the control group（ P 0. 01）; the incidence of DVT in the observation group was lower than that in the control group（ P 0. 05）. Conclusion： The intermittent pneumatic compression can promote blood circulation of lower limbs and effectively prevent the incidence of DVT of lower extremity in critically ill patients. The effect of intermittent pneumatic compression is better than that of graded compression elastic stockings in the prevention of DVT.
