Efficacy of Local Direct Median Nerve Block

Status Completed

Clinical Trial Summary

Carpal tunnel syndrome is the most common compressive neuropathy. Carpal tunnel release is indicated when failed conservative treatment. Although it can be done either with local anesthesia or brachial plexus block, there is no gold standard of anesthetic choice. The study is conducted to compare the efficacy of two methods and we hypothesized that the local direct median nerve block has effectiveness in intraoperative pain control not inferior to brachial plexus block in endoscopic carpal tunnel release.

Clinical Trial Description

The study is randomized-control trial conducted in single center (Orthopaedic department, Faculty of medicine, Thammasat university) The patients with failed conservative treatment of carpal tunnel syndrome confirmed by EMG are enrolled and ramdomized with computerized block-of-4 method.The local direct median nerve block is done by the surgeon and brachial plexus block in done by single anesthesiologist after that the patient will be operated with 1-portal endoscopic carpal tunnel release (Agee technque) by single surgeon. Immediate postoperative the blinded observer will ask the patient about interaoperative pain in visual analog scale then the pateint is asked to record the 2-hr, 4-hr ,6-hr and 12-hr postoperative pain in case record form.The patient will return the case record form at 2-week and also stitched off the wound then next follow up will be 4, 12, 24 weeks to assess functional outcome (Thai version Bonton questionaire) ;
