50 patients undergoing carpal tunnel release were randomized to receive either a silicone ring tourniquet or pneumatic tourniquet during surgery, to compare the pain levels between patients of each group. After 30 days, no tourniquet-related complications or any wound infections were reported by any of the patients. Patients in the silicone ring tourniquet group experienced significantly less pain immediately prior to having the device removed in comparison to patients who received a pneumatic tourniquet. Overall, patients who received the pneumatic tourniquet had a significantly larger increase in pain from time of tourniquet application to just prior to tourniquet removal.
