Abstract:
PURPOSE: To evaluate the possibility of lowering tourniquet pressure to 200 mmHg during total knee arthroplasty (TKA) by pressing the femoral artery. Lowering the toniquette pressure can attribute to minimize the soft tissue damage and pain after the operation. MATERIALS AND METHODS: We analyzed patients who had TKA from Sep 16th, 2010 to Mar 3rd, 2011. Among them, 35 patients (test I) had operations on both knees, and 50 patients (test II) underwent operation on one knee. We excluded the patients who had a previous operation, infection, or bleeding tendency. We put a cotton roll at the antero-medial side of the thigh just under the tourniquet in order to apply more pressure on the femoral artery that is scanned by ultrasonography. We scored 0 on non-bleeding, 1 on bleeding that did not affect the operation, and 2 on bleeding which disturbed the operation. RESULTS: In test I, the group which applied 200 mmHg with local pressure, 24 patients (68.6%) scored 0, 9 patients (25.7%) scored 1, and two patients (5.7%) scored 2. In the other group used pressure 250 mmHg, however, 31 patients (88.6%) scored 0, 4 patients (11.4%) scored 1, and no one scored 2 (p=0.039). Totally, in the 200 mmHg group with local pressure, 33 patients had no problem in surgery, and only for 2 patients (5.7%), we had to increase pressure. For the patients with 250 mmHg, however, we had to increase pressure on nobody (0%). In test II, in the group which had operation on one knee with 200 mmHg with local pressure, 14 patients scored 0, 8 patients scored 1, and one patient scored 2. Also in the 250 mmHg group, 24 patients scored 0, 2 patients scored 1, and one patient scored 2. (p=1.000). Overall results demonstrate no differences in bleeding that disturb operations statistically. CONCLUSION: Even with a little more bleeding compared to the 250 mmHg group, 94.8% of patients can have operation with no bleeding problems by using a cotton roll and the pressure 200 mmHg. For successful operations, there is no difference between groups using 250 mmHg and 200 mmHg with local pressure on femoral artery.
