The prevention effect of intermittent pneumatic compression pump on venous thrombosis in patients undergoing knee joint replacement

Objective To investigate the prevention effect of intermittent pneumatic compression pump on DVT in patients undergoing knee joint replacement.Methods A total of 318 patients with knee joint replacement in our hospital were selected as study objects,and 108 cases with routine nursing were as control group,and 210 cases with intermittent pneumatic compression were as observation group.The changes of D-D,PLT and Hb,and DVT of two groups were compared.Results PLT and D-D after 6 d of the operation in the observation group was lower than that in the control group,the difference was statistically significant(P ＜0.05).Venous velocity of lower limb after 6 d of operation in the observation group was quicker than that in the control group,the detection rate of DVT was lower than that in the control group,DVT diameter was less than that in the control group,the differences were statistically significant (P ＜ 0.05).Conclusion Intermittent pneumatic compression pump can reduce PLT,D-D and the incidence of DVT after knee replacement.
