The average tourniquet time for this cohort was 16 minutes (range, 9-19 minutes), and the average volume of lidocaine (0.5% plain) injected was 44 mL (range, 30-70 mL). A tourniquet time of 17 minutes or less was observed in 339 patients, and 170 patients had tourniquet times of 15 minutes or less. By means of an observer-blinded, randomized controlled trial, the analgesic efficacy of an upper-arm Bier's block and a forearm mini-Bier's block will be investigated in patients undergoing hand surgery.
