Anticoagulation for thromboprophylaxis after THA and TKA has not been confirmed to diminish all-cause mortality. We determined whether the incidence of all-cause mortality and pulmonary embolism in patients undergoing total joint arthroplasty differs with currently used thromboprophylaxis protocols. We reviewed articles published from 1998 to 2007 that(More)
Venous thromboembolic disease remains the most common and potentially fatal complication after total hip arthroplasty (THA). Proximal femoral deep vein thrombosis (DVT) is especially prone to propagate and embolize. The authors' hypothesis was that intraoperative intravenous heparin administration could reduce proximal DVT in THA. There were 286 patients(More)
The activation of the clotting cascade leading to deep venous thrombosis begins during total hip arthroplasty, but few studies have assessed changes in coagulation during surgery. A better understanding of thrombogenesis during total hip arthroplasty may provide a more rational basis for treatment. In 3 separate studies, the following observations were(More)
The toxicity and pharmacokinetic properties of a drug determine whether hemodialysis and/or hemoperfusion are indicated in acute intoxications. Valproic acid is considered unremovable by hemodialysis because of the high protein binding of 90%-95%. A 27-year-old male with a history of seizures was admitted to the emergency room because of coma,(More)
UNLABELLED We evaluated the safety and efficacy of a multimodal approach for prophylaxis of thromboembolism after total hip arthroplasty, which includes preoperative discontinuation of procoagulant medication; autologous blood donation; hypotensive epidural anesthesia; intravenous administration of heparin during surgery and before femoral preparation;(More)
Extradural anaesthesia is associated with lower incidences of deep vein thrombosis after total knee arthroplasty. It is not known if the type of anaesthesia influences thrombogenesis or fibrinolysis during knee surgery performed under tourniquet. We studied 31 patients allocated randomly to receive either extradural or general anaesthesia for primary(More)
BACKGROUND Thrombogenesis in total hip replacement (THR) begins during surgery on the femur. This study assesses the effect of two doses of unfractionated intravenous heparin administered before femoral preparation during THR on circulating markers of thrombosis. METHODS Seventy-five patients undergoing hybrid primary THR were randomly assigned to receive(More)
BACKGROUND AND OBJECTIVES Recovery of cognitive function immediately after major surgery has not been previously reported, partly because of residual drug effects and pain. METHODS Changes in cognitive function were assessed using the Stroop Color and Word Test (SCWT), which was performed preoperatively, and 1 and 2 hours after total-hip replacement(More)
Lower rates of deep vein thrombosis have been noted following total hip replacement under epidural anesthesia in patients receiving exogenous epinephrine throughout surgery. To determine whether this is due to enhanced fibrinolysis or to circulatory effects of epinephrine, 30 patients scheduled for primary total hip replacement under epidural anesthesia(More)
Four cases of tardy ulnar nerve palsy associated with a cubitus varus deformity of the elbow secondary to a supracondylar fracture of the humerus are presented. All patients had surgical management of their ulnar nerve palsy. In two patients, the ulnar nerve was entrapped by scar tissue at the abnormal position and the nerve developed a sharp V-shaped kink(More)
