title: Evaluation of surgical treatment of carpal tunnel syndrome using local anesthesia.
abstract: OBJECTIVE
  To evaluate the results and complications from surgical treatment of carpal tunnel syndrome by means of an open route, using a local anesthesia technique comprising use of a solution of lidocaine, epinephrine and sodium bicarbonate.
  
  
  METHODS
  This was a cohort study conducted through evaluating the medical files of 16 patients who underwent open surgery to treat carpal tunnel syndrome, with use of local anesthesia consisting of 20 mL of 1% lidocaine, adrenaline at 1:100,000 and 2 mL of sodium bicarbonate. The DASH scores before the operation and six months after the operation were evaluated. Comparisons were made regarding the intensity of pain at the time of applying the anesthetic and during the surgical procedure, and in relation to other types of procedure.
  
  
  RESULTS
  The DASH score improved from 65.17 to 16.53 six months after the operation (p < 0.01). In relation to the anesthesia, 75% of the patients reported that this technique was better than or the same as venous puncture and 81% reported that it was better than a dental procedure. Intraoperative pain occurred in two cases. There were no occurrences of ischemia.
  
  
  CONCLUSIONS
  Use of local anesthesia for surgically treating carpal tunnel syndrome is effective for performing the procedure and for the final result.
