Abstract:
Objective:To study and analyze the risk factors of deep Venous Thrombosis of Lower limbs in patients with Orthopaedic bed rest.
Methods:273 cases of patients with bed rest who were treated by Orthopaedic operation from November 2015 to March 2016 and from November 2016 to March 2017 in our hospital were.collected and divided into 2 groups according to whether there were deep venous thrombosis after operation, and A group had 232 patients who did not have deep venous thrombosis of lower limbs after Operation. B Group had 41 patients who had deep venous thrombosis of lower limbs after Operation. The two groups of patients were treated with orthopedic treatment, the researchers recorded the basic data of two groups of patients, and analyzed the risk factors of lower extremity deep venous thrombosis in patients with orthopedic Bed rest.
Results:In group B, patient ratio of age greater than 65 years old, with a body mass index (BMI) of more than 25 kg/m2, with chronic diseases, bed rest for more than 5 days after operation, triglyceride index ≥ 1.7 mmol/L D-dimer ≥ 500 μgP/L, operating time over 4 h were 54.10% (23/41), 58.54% (24/41), 75.61% (31/41), 60.98% (25/41), 58.50% (24/41), 63.41% (26 /41), 48.78% (20/41), respectively.In group A, patient ratio of age greater than 65 years old, with a body mass index (BMI) of more than 25 kg/m2, with chronic diseases, bed rest for more than 5 days after operation, triglyceride index ≥ 1.7 mmol/L D-dimer ≥ 500ugP/L, operating time over 4 h were 24.14%(56/232), 23.28% (54/232), 13.36% (31/232), 23.28% (54/232), 21.12% (49/232), 10.78% (25/232), 9.91% (23/232), respectively, The difference between the two groups was statistically significant (χ2=3.602~11.623, all P < 0.05); Related risk factors for deep venous thrombosis in lower limbs logistic regression analysis showed that age greater than 65 years old, with a body mass index (BMI) of more than 25 kg/m2, with chronic diseases, bed rest for more than 5 days after operation, triglyceride index ≥ 1.7 mmol/L D-dimer ≥ 500 μg/L, operating time over 4 h were the related risk factors for deep venous thrombosis in patients with bed rest after operation.
Conclusion:the risk factors for deep venous thrombosis of lower limbs in the elderly patients with bed rest after orthopedic operation are mainly age greater than 65 years old, with a body mass index (BMI) of more than 25 kg/m2, with chronic diseases (such as hypertension, diabetes, etc.), bed rest for more than 5 days after operation, triglyceride index ≥ 1.7 mmol/L D-dimer ≥ 500 μg/L, operating time over 4 h, nursing staff should carry out nursing intervention according to the risk factors related to deep venous thrombosis of lower limbs to avoid the formation of deep vein thrombosis of lower limbs as far as possible.
