间歇性气压治疗仪预防卒中患者下肢深静脉血栓的临床研究

Research on Intermittent Pneumatic Compression in the Prevention of Deep Venous Thrombosis after Stroke

目的:探讨间歇性气压治疗仪对卒中患者下肢深静脉血栓形成的预防效果。方法:将180例患者随机分为对照组和观察组,对照组采取常规预防护理,观察组在常规预防护理的基础上采取间歇性气压治疗仪进行治疗。比较两组患者DVT的发生率,观察两组患者肢体周径差值和凝血指标变化。结果:观察组患者DVT发病率为1.1%,明显低于对照组的10%,具有显著性差异(P<0.05)。在治疗10d后和20d后,观察组的偏瘫侧肢体的周径变化均明显小于对照组,且具有显著性差异(P<0.05)。治疗后,对照组较观察组PC和FIB升高、APTT缩短、TT延长、PT缩短,差异均有统计学意义(P<0.05)。结论:间歇性气压治疗仪对卒中患者下肢深静脉血栓形成有一定预防作用,并能减轻肢体水肿。

Objective:To explore the preventive clinical effect of intermittent pneumatic compression on deep venous thrombosis for patients after stroke.Methods:180patients were admitted to the control group treated by routine preventive measures;observation group added by intermittent pneumatic compression based on the routine preventive measures.DVT,coagulation index and limbs circumference were tested.Results:The incidence rate(1.1%)of DVT in the observation group were significantly lower than that(10%)in the control group(P<0.05);Variation of circumference of limbs in observation group were less than control group in the10d and20d after treatment(P<0.05),There was a significant decrease in platelet counts,fibrinogen and TT and notable increase in APTT,PT in observation group(P<0.05).Conclusions:IPC is effective as a means of preventing deep venous thrombosis and alleviating edema of limbs for patients after stroke.
