Patients will receive 20 ml of 1% lidocaine with 1:100,000 epinephrine (buffered 10:1 with 8.4% sodium bicarbonate). Thirty minutes before carpal tunnel release surgery, 10 mL will be injected subcutaneously, and 10 mL will be injected into the carpal tunnel. Patients will go under open carpal tunnel release without a tourniquet.

Thirty minutes before carpal tunnel release surgery, 10 mL will be injected subcutaneously, and 10 mL will be injected into the carpal tunnel. Patients will go under open carpal tunnel release using a hemostatic cuff. The hemostatic cuff will be insufflated at the level of the arm at a pressure of 100 mmHg higher than the patient's systolic pressure. The cuff will be removed once wound closure is complete.
