Objective To determine the factors contributing to the development of deep vein thrombosis (DVT) in the lower extremity in patients after hip or knee arthroplasty and hip fracture internal fixation.Methods One hundred and forty-seven consecutive patients receiving hip or knee arthroplasty and hip fracture internal fixation from 2004 to 2005 were included in this study. Their age ranged from 33 to 92 years. Duplex color ultrasonic inspection was performed on veins of the bilateral lower extremities before operation and 2 weeks after operation for detection of DVT. The patients were divided into a DVT group and a DVT-free group based on the development of DVT after operation. Detailed perioperative clinical information about the patients, surgery and anesthesia was collected.Results Lower extremity DVT was found in 42.2% of the patients after operation, while the incidence of proximal DVT was 2.7%. Compared with the DVT-free group, the usage rate and dosage of ephedrine increased significantly, the duration of anesthesia was significantly longer, and the white blood cell count (WBC) on the 1st postoperative day and the highest WBC count were significantly higher in the DVT group(P<0.05). Logistic regression analysis indicated that the above factors were closely related to DVT.Conclusion Duration of anesthesia > 3 h, ephedrine administration and a marked increase in WBC count after operation are the risk factors for DVT in the lower extremities in patients after hip or knee arthroplasty and hip fracture internal fixation.
