Abstract
We carried out a prospective randomized trial in 38 patients to compare intravenous regional anaesthesia with local anaesthesia in endoscopic carpal tunnel release using the Agee single-portal technique. There was no significant difference in reported pain during surgery. Immediately after surgery, patients in the local anaesthesia group reported significantly less pain in the hand and at the tourniquet. Two hours after surgery, patients in the local anaesthesia group reported significantly less hand pain. Moreover, significantly fewer patients in the local anaesthetic group required additional analgesics during the first 2 hours after operation. We conclude that local anaesthesia reduces post-operative pain in endoscopic carpal tunnel release compared with intravenous regional anaesthesia.
