Effects of predictive phased intervention on preventing lower extremity deep venous thrombosis in ICU patients

Abstract

Objective To evaluate the preventive effects of predictive phased intervention on lower extremity deep vein thrombosis in ICU patients. Methods A total of 82 cases of critically ill patients admitted to our hospital from June 2013 to June 2016 were divided into observation group and control group according to the random number table method, with 41 cases respectively. Patients in the observation group received predictive phased intervention, while patients in the control group received routine nursing intervention. After 4 weeks of intervention, the lower extremity deep venous thrombosis rate, lower limb perimeter and blood flow velocity of lower extremity venous were compared between two groups. Results The incidence of lower extremity deep venous thrombosis was 2.44% in the observation group and 19.51% in the control group. The difference between two groups was statistically significant (χ2=6.604, P<0.05) . After the intervention, the lower limb perimeter of patients in the observation group was (30.01±2.34) cm, which was significantly lower than that of the control group; the venous blood flow velocity of the lower extremity of patients in the observation group was (25.43±3.01) cm/s, which was significantly higher than that of the control group (t=2.285, 2.357; P<0.05) . Conclusions Predictive phased intervention has obvious advantages in the prevention of lower extremity deep venous thrombosis in ICU patients and it is worth clinical promotion.
