RESUMO
Objective To investigate the effects of Physiotherapy in the prevention of lower extremitydeep venous thrombosis in patients with colorectal tumors after operation. Methods About 55 cases of inpatients admitted to the hospital from November 2014 to November 2015 were selected as the control group, and they were given routine nursing before and after operation. Another 55 cases of inpatients admitted to the hospital from November 2015 to November 2016 were selected as the observation group. On the basis of the control group, the observation group were treated with Physiotherapy in 24h after operation, 30min for once, twice/d, lasting for 7 days. The coagulation function , lower extremity deep venous flow velocity and the incidence of deep venous thrombosis in two groups were compared before operation and 7 days after operation. Result About 7 days after operation, levels of fibrinogen and D-dimer in the observation group were lower than those in the control group (P<0.01), the lower extremity deep venous blood flow velocity was higher than that in the control group (P<0.01), and the incidence of lower limb deep venous thrombosis was lower than that in the control group (all P<0.05). Conclusion Physiotherapy can improve the coagulation function in patients undergoing colorectal operation, improve the lower extremity deep venous flow velocity and reduce the incidence of lower extremity deep venous thrombosis.
