摘要
目的 探讨空气压力波对脑卒中患者下肢深静脉血栓形成的预防作用及彩色多普勒超声（CDUS）技术的应用价值.方法 72例脑卒中患者按随机数字表法分为观察组（37例）和对照组（35例）,对照组予常规护理与药物、康复治疗;观察组加用空气压力波治疗,疗程15 d.治疗前后行下肢静脉CDUS观察深静脉血栓（DVT）形成及血流动力学变化,并与X线静脉造影检查对照.结果 观察组DVT发生率显著低于对照组（2.7％与20.0％,x2=5.449,P＜0.05）.治疗前后比较,观察组股、胭静脉血流速度和平均反流时间差异均有统计学意义（t=8.503、4.254、8.587、2.062,,均P＜0.05）;而对照组仅胭静脉血流速度差异有统计学意义（t=6.895、2.116、4.169,均P＜0.05）.与X线血管造影比较,CDUS诊断8例DVT均相符,但对照组漏诊1例.结论 空气压力波能有效减少脑卒中患者DVT发生.CDUS能准确诊断DVT形成,且能了解血管内血流动力学变化,对监测DVT防治效果具有重要的临床价值.
Objective To explore the effect of air pressure wave on the prevention of lower limb deep venous thrombosis in patients with cerebral stroke and the application value of color Doppler ultrasound （CDUS）. Methods 72 stroke patients were randomly divided into experimental group （ n = 37 ） and control group （ n = 35 ） by random digits table. The control group received routine nursing, conventional and rehabilitation therapy. The experi- mental group was treated by the air pressure wave for 15 days on the basis of the control group. DVT formation of lower extremities and hemodynamic changes before and after treatment was observed by CDUS , and the results werecompared with the X-ray phlebography examination results. Results CDUS displayed the incidence rate of DVT in the experimental group was significantly lower than that in the control group （ 2.7% vs 20.0%, ~2 = 5. 449, P 〈 0.05 ）. The changes of blood flow velocity and the average reflux time of femoral, popliteal vein in the experimental group had significant differences between before and after treatment （ t = 8. 503,4.254,8. 587,2. 062, all P 〈 0.05 ） ; and in the control group, only popliteal vein blood flow velocity had statistically significant difference （ t = 6. 895, 2. 116,4. 169 ,all P 〈 0.05 ）. Compared with the X-ray angiography ,8 cases of DVT diagnosed by CDUS were con- sistent,but 1 case of DVT in the control group was missed diagnosis. Conclusion Air pressure wave can effectively reduce the occurrence of DVT in patients with cerebral stroke. CDUS can accurately diagnose the DVT formation, and can help to understand the hemodynamic change, it has important clinical value for monitoring the preventive effect of DVT.
