The Comparative Study Of Different Tourniquet Technologies In Total Knee Arthroplasty

ObjectivesTo objectively assess the effection on Lower Extremity Swelling of the patients who receiv TKA for different tourniquet technologies.MethodsA prospective study is going to carry out in 40 patients who will receive TKA.20 patients will halfway tourniquest technology, and the others will receive receive omnidistance tourniquest technology. The circumference of lower extremity,RBC,Hb and HCT which recorded in Preoperative and postoperative 1,3,7 days will be compared with.Result1.In the two groups, Red blood cell count, Hemoglobin concentration, HematoCritwas significant difference form those before operation(P<0.05);2. In the treated group, the time of using tourniquest technology was lower than the control group, but the total losing blood was not significant defference(P>0.05);3. In the two groups, the lower limb weeks diameter was not significant defference before operation(P>005); But in the treated group, the lower limb weeks diameter in the 1st day,in the 3th day was significant defference than those in the control group at the same day after operation (P<0.05); 4. In the treat group, the lower limb swelling degree in the 1st day,in the 3th day was significantly lower than those in the control group at the same day after operation (P<0.05)ConclusionHalfway tourniquest technology will not increase total blood loss, but will reduce the complications of tourniquest technology and improve the early postoperrative clinical effect.
