Venaflow法预防妇产科高危患者深静脉血栓形成的临床效果

Clinical effect of venaflow compression method in the prevention of deep vein thrombosis for the high risk patients in gynaecology and obstetrics department

目的研究观察venaflow压迫法预防妇产科高危患者深静脉血栓形成(DVT)的临床效果。方法将我科80例DVT高危风险患者随机分为两组:实验组采用venaflow的小腿充气压迫法,对照组采用常规小腿按摩法加序贯加压袜,配合双下肢等长收缩运动、平衡饮食及对症处理,分别于第1、7天对所有患者进行检查症状体征、下肢静脉彩超和血浆D二聚体测定,按照DVT诊断流程判断。结果两组均未见严重下肢DVT和肺栓塞(PE),实验组下肢DVT发病率7.5%,双下肢血栓1例、单肢体血栓2例;对照组下肢DVT发病率25%,双下肢血栓2例、单肢体血栓8例;实验组显著地降低静脉血栓的风险。另外,实验组第7天静脉流速差异有统计学意义(P<0.05)。结论 venaflow压迫法明显地加快静脉血流速,有助于预防妇产科高危患者深静脉血栓形成,降低其静脉血栓发生风险。

Objective To study and observe the clinical effect of venaflow compression method in the prevention of deep vein thrombosis（DVT） for the high risk patients in gynaecology and obstetrics department. Methods Eighty high risk patients with DVT in our department were randomly divided into two groups, the patients in the experimental group used calf inflatable venaflow compression method, while the patients in the control group used conventional calf massage with sequential compression stockings, and did double lower limbs isometric exercise, ate balanced diet and implemented symptomatic treatment. The symptoms and signs, lower limbs venous color Doppler ultrasonography and plasma D-dimer of all patients were examined and determined respectively at hh, 7th day, and were judged according to DVT diagnosis process. Results The two groups had no severe lower limbs DVT and pulmonary embolism（PE）. In the experimental group, the incidence of lower limbs DVT was 7.5%, 1 case happened double lower limbs thrombosis, 2 cases happened single limb thrombosis; In the control group, the incidence of lower limbs DVT was 25%, 2 cases happened double lower limbs thrombosis, 8 cases happened single limb thrombosis; The patients in the experimental group significantly reduced the risk of vein thrombosis. In addition, there was a statistically significant difference in the seventh days venous velocity between two groups （P 〈 0.05）. Conclusion The venaflow compression method can significantly accelerate the vein blood velocity, and contribute to the prevention of DVT for the high risk patients in gynaecology and obstetrics department, and reduce the risk of vein thrombosis.
