rarily stopped in preparation for surgery and were therefore excluded from the study. The remaining 93 patients continued their normal AT regimen through surgery. There were 69 patients taking aspirin, 7 taking warfarin, 9 taking clopidogrel, 1 taking dabigatran, 3 taking warfarin plus aspirin, and 4 taking dual antiplatelet therapy. Patients treated with AT agents were older than the control group (mean, 66.1 years vs 56.9 years; P < .001). They were also more likely to be male (96.8% vs 84.4%; P = .002), diabetic (55.9% vs 22.9%; P < .001), and nonsmokers (82.8% vs 71.7%; P = .04). Average preoperative median nerve motor latencies at the wrist did not differ significantly between the AT user and non-AT user groups (6.9 milliseconds vs 6.7 milliseconds; P = .44), nor did the rate of intraoperative tourniquet use (32% vs 56% for AT user and nonuser groups, respectively; P = .22). Estimated blood loss was higher in the no-tourniquet group for both AT users (4.33 mL vs 3.22 mL; P = .02) and non-AT users (4.21 mL vs 3.13 mL; P = .006). Mean operating time was shorter in the no-tourniquet group for both those treated with AT agents (20.1 minutes vs 25.7 minutes; P = .001) and those not treated with AT agents (22.40 minutes vs 24.52 minutes; P = .13). There was no statistical difference in EBL (3.94 mL vs 3.89 mL; P = .87) or operative time (22.0 minutes vs 23.0 minutes; P = .38) in AT and non-AT patient groups overall. Rates of postoperative complications were similar between the AT group and the non-AT group (5.4% vs 4.9%; P > .99). No hematomas or neurological complications were reported, and no patients required reoperation during the study period. Overall, 91.8% of patients reported improvement of symptoms postoperatively, with a mean follow-up time of 3.3 months (Table).
