Analysis Of The Incidence Of Deep Venous Thrombosis After Total Keen Arthroplasty In Different Anaesthesia Way

Objective: To compare the incidence of deep venous thrombosis after total keenarthroplasty in general anaesthesia and in continuous epidural anaesthesia.Methods:From September2009to January2011, according to the selection criteria,76patientswere selected into this study. Were divided into2groups at random,4patients are get ridof before the surgical operation.36in the general anaesthesia group and36in theepidural anaesthesia group with a mean age of66years (range50~80years). ColorDoppler ultrasonography was used to detect deep venous thrombosis of bilateral lowerextremities in all patients befor operation and at5～7days after operation. Color Dopplerultrasonography was used again to detect deep venous thrombosis at15day afteroperation. And finally the result were used to analyze the incidence of deep venousthrombosis. Results: There were14patients who developed deep venous thrombosisafter operation. The incidence of deep venous thrombosis in all patients was19.44%(14/72). The incidence of deep venous thrombosis in general anaesthesia groups was30.56%(11/36) and the incidence of deep venous thrombosis in continuous epiduralanaesthesia groups was8.33%(3/36). The incidence of deep venous thrombosis ingeneral anaesthesia group were significantly higher than continuous epiduralanaesthesiagroup (P＜0.05). Conclusion: continuous epidural anaesthesia can effectively reduce theincidence of deep venous thrombosis after total knee replacement than those patients whomake use of general anaesthesia.
