：Objective To investigate the nursing interventions based on Caprini risk assessment scale in reducing the risk of deep-venous thrombosis(DVT)after unilateral total hip replacement(THR). Methods 〓Totally 150 hospitalized patients with THR for ischemic necrosis of the femoral head were randomly divided into the control group and the observation group, with 75 cases in each group. The routine nursing management was carried out in the control group. In the observation group, patients were evaluated with Caprini risk assessment scale, and individualized interventions were made according to level of risk to DVT development. The lower-limb skin temperature, D-dimer levels, amount of bleeding, changes in diameter of lower limb were observed, and the incidence of DVT was compared between two groups. Results 〓The changes in diameter of lower limb, amount of bleeding and D-dimer levels at 8 and 72 hours after surgery were lower in the observation group than those in the control group(P0.05). The incidence of DVT in the observation group was lower than that in the control group(1.33% vs. 9.33%, P0.05). Conclusion 〓The risk assessment of DVT by Caprini risk assessment scale is the key to prevent DVT in hospitalized THR patients and lay the foundation for implementation of individualized nursing interventions.
