The clinical study of early systematic nursing intervention on the prevention of venous thrombus of low limbs in ICU patients

Abstract

Objective To explore the clinical meaning of early systematic nursing intervention on the prevention of low limbs venous thrombus in ICU patients.Methods Totals of 120 patients in ICU were randomly divided into two groups by entering order number,odd numbers were experimental group(60 cases)and double numbers were control group(60 cases).Experimental group received early systematic nursing intervention while control group received ICU conventional nursing.All patients were measured the lower limb diameter per day,and were received colour Doppler examination to tested their femoral venous blood velocity in first,seventh and fourteen day of ICU,and their femoral venous blood velocity and incidence of low limbs venous thrombus were compared.Results No difference of femoral venous blood velocity in two groups was founded before intervention (P ＞0.05).After intervention,femoral venous blood peak velocity and average velocity of seventh and fourteen day in experimental group was(52.8 ± 9.6),(52.6 ± 8.8)and(34.2 ± 6.9),(35.3 ± 7.2),respectively,and higher than(41.3 ±7.8),(42.5 ±7.6)and(22.5 ±7.1),(23.7±6.6)in control group,differences between two groups were statistically significant(t =2.724,3.125,2.722,3.114 ;P ＜ 0.05); the incidence of low limbs venous thrombus in experimental group was lower than that of control group,and the difference was statistically significant(x2 =4.904,P ＜ 0.05).Conclusions Adopting early systematic nursing intervention can improve the femoral venous blood velocity,and effectively prevent and reduce the incidence of low limbs venous thrombus of ICU patients.
