不同气压治疗时长在重症患者DVT形成预防中的效果对比

Comparison of the Effects of Different Air Pressure Treatment Durations in the Prevention of DVT Formation in Critically Ill Patients

目的对重症患者下肢深静脉血栓(deep vein thrombosis,DVT)形成预防中应用不同气压治疗时长的效果进行分析,以此寻找出预防效果最佳的气压治疗时长。方法随机选取2017年12月—2019年12月医院重症监护室内接收重症患者150例作为研究病例,使用计算机抽号分为对照组、观察1组、观察2组,对照组患者气压治疗时长为30 min/次,观察1组患者气压治疗时长为1 h/次,观察2组患者气压治疗时长为2 h/次,对比三组患者DVT发生率、深部组织损伤发生率以及首次治疗前后下肢股深静脉血流速度。结果经由统计,三组患者DVT发生率对比,差异无统计学意义(P>0.05),但观察1组、观察2组患者DVT发生率较之对照组要少。观察2组患者深部组织损伤发生率高于对照组、观察1组(P<0.05);观察1组患者深部组织损伤发生率与对照组相比,差异无统计学意义(P>0.05)。治疗前,三组患者下肢股深静脉血流速度对比,差异无统计学意义(P>0.05);治疗后,三组患者下肢股深静脉血流速度均有所提升,且观察1组、观察2组患者下肢股深静脉血流速度均高于对照组(P<0.05)。结论在重症患者下肢深静脉血栓形成预防中应用1 h/次的气压治疗效果最佳,可有效提升患者下肢股深静脉血流速度,降低DVT和深部组织损伤发生率。

Objective To analyze the effects of different air pressure treatment durations in the prevention of deep vein thrombosis(DVT)in severely ill patients,so as to find the best prevention effect of air pressure treatment duration.Methods A random selection of 150 critically ill patients in the intensive care unit of our hospital from December 2017 to December 2019 were selected as the study cases,and they were divided into the control group,the observation group 1,and the observation group 2 using a computer.The patients in the control group were treated with air pressure for 30 min/time.The patients in the observation group 1 were treated with air pressure for 1 h/time,the patients in the observation group 2 were treated with air pressure for 2 h/time,comparing the incidence of DVT,deep tissue injury and the blood flow velocity of the deep femoral vein of the lower limbs before and after the first treatment.Results According to statistics,there was no significant difference in the incidence of DVT among the three groups of patients(P>0.05),but the incidence of DVT in observation group 1 and observation group 2 was lower than that in the control group.The incidence of deep tissue injury in observation group 2 was higher than that in control group and observation group 1(P<0.05);the incidence of deep tissue injury in observation group 1 was not statistically different from that in control group(P>0.05).Before treatment,there was no significant difference in the blood flow velocity of the deep femoral vein of the lower limbs of the three groups of patients(P>0.05);after treatment,the blood flow velocity of the deep femoral vein of the lower limbs of the three groups of patients increased,and the blood flow velocity of the deep femoral vein of the lower limbs of the observation group 1 and group 2 was higher than that of the control group(P<0.05).Conclusion The application of 1 h/time air pressure therapy in the prevention of deep venous thrombosis of severely ill patients is the best.It can effectively increase the blood flow velocity of the deep femoral vein of the patients and reduce the incidence of DVT and deep tissue injury.
