To investigate the effects of Caprini risk assessment model on the prevention and control of lower extremity deep venous thrombosis after craniocerebral operation.

Patients with traumatic brain injury who had undergone brain surgeries in the First Affiliated Hospital of Zhengzhou University from June 2011 to May 2015 were enrolled in the research. A total of 188 patients who were treated from June 2011 to May 2013 were recruited to control group, and given routine antithrombotic intervention. A total of 192 patients from June 2013 to May 2015 were selected as the observation group, and evaluated with the Caprini risk assessment model.The incidence of lower limb swelling, the incidence of deep vein thrombosis and the incidence of pulmonary embolism were compared between the two groups 7 days after surgery.

The proportion of high risk and extremely high risk of thrombosis was 45.38% and 19.79% in the observation group, and 46.28% and 19.15% in the control group respectively. There was no statistical significant difference between the two groups (χ²=2.695, P>0.05) .The proportion of patients' occurrence of lower limb swelling and lower extremity deep vein thrombosis 7 days after surgery in the observation group was 2.08% and 1.04% respectively, and both lower than the control group with statistical significance (χ²=18.245, 13.099; P<0.01) . There was 1 cases of pulmonary embolism in the observation group, and 2 cases in the control group, and there was no statistical significance (P>0.05) .

Using Caprini risk assessment model to assess the risk of thrombosis in patients with brain surgery can effectively reduce the incidence of lower limb swelling and deep venous thrombosis.
