Objective To investigate the risk factors associated with deep vein thrombosis in geriatric patients with hip fracture during perioperative period.Methods Retrospectively analyzed the clinical data of 363 elderly patients with hip fracture aged 60 years and over who were treated in Pudong New District People's Hospital from January 2016 to December 2018. There were 118 males and 245 females, ranged from 60 to 97 years old, with an average age of (73.9±8.6) years. There were 134 femoral intertrochanteric fractures and 229 femoral neck fractures, in which 184 were treated by hip replacement and 179 were treated by internal fixation. Color Doppler ultrasound was used to diagnose deep vein thrombosis of lower limbs. Clinical data were collected including general information (gender, age, BMI, comorbidity, smoking history, injury type, and time from injury to surgery), laboratory examination (plasma D-dimer level), and operation-related information (operation time, blood loss, blood transfusion, and surgical method). All data were statistically analyzed.Results DVT was detected in 56 of 363 cases, with an overall incidence of 15.4%. The comparison of general data showed that the incidence of DVT was higher when age≥80 years, BMI≥25 kg/m2, smoking history, history of cardiovascular disease, high energy injury, injury to operation time>2 d (P<0.05). The incidence of DVT was significantly higher when D-dimer≥5 μg/mL (P<0.05). The comparison of operation-related data showed that the incidence of DVT was significantly higher when operation time>2 h, intraoperative blood loss >200 mL, blood transfusion, and artificial joint replacement (P<0.05). Multivariate logistic regression analysis showed that age (≥80 years), smoking history, operation time (>2 h), and artificial joint replacement and D-dimer (≥5 μg/mL) were independent risk factors for DVT after hip fracture surgery in the geriatric patients.Conclusion The incidence of DVT after hip fracture surgery in the geriatric patients is high, and early preventive measures should be taken to reduce the incidence of DVT after surgery according to the risk factors during the perioperative period. |
