Abstract
Aims: To evaluate the inßuence of the type of anesthesia on the superior efþcacy of fondaparinux over enoxaparin in preventing venous thromboembolism (VTE) in orthopedic surgery (RRR > 50%; P< 0.0001). Methods: 4 randomized, double-blind trials were performed: 2 in hip replacement (THR), 1 in North America (NA) and 1 in Europe; 1 in knee surgery (MKS); and 1 in hip-fracture surgery (HF). The choice of anesthesia was left to the investigators. A predeþned covariate analysis according to the type of anesthesia was performed on primary efþcacy.
Conclusions: Fondaparinux once-daily started postoperatively provided superior efþcacy versus enoxaparin in preventing VTE whatever the type of anesthesia and may improve convenience in current practice.
