Abstract
The benefit/risk ratio of administering heparin during spinal anaesthesia in patients undergoing total hip replacement (THR) has not been studied widely. We conducted a prospective, randomized, double-blind study to compare low molecular weight heparin (LMWH) for 10 days and placebo in patients undergoing THR performed under spinal anaesthesia associated with gradual compression stockings. Efficacy was assessed by systematic bilateral ascending venography on day 10 +/- 2 in a sequential analysis. Among the 170 patients enrolled, data were available in 153 patients. In the LMWH group (n = 78) the total incidence of deep vein thrombosis (DVT) was 14.1% compared with 37.3% in the placebo group (n = 75) (P = 0.0016). No gross neurological sequelae were observed during the study. This study showed that the addition of LMWH in patients undergoing THR under spinal anaesthesia and wearing gradual compression stockings significantly decreased the incidence of venogram-proved DVT.Keywords
