RESUMEN
Carpal tunnel release can be performed under general or local anaesthetic. However, many surgeons believe the upper arm tourniquet is not tolerated by the patient when awake. We use a forearm tourniquet for carpal tunnel decompression under local anaesthesia. The aim of this study is to assess patient tolerance of the technique. Between January 1st 1996 and December 31st 2000, 74 patients had carpal tunnel release performed using local anaesthesia. We sent a postal questionnaire to each, asking the patient to rate different aspects of the procedure. Fifty-eight patients replied (78% response). Forty-four of the respondents (76%) tolerated the tourniquet well, finding it to be 'no problem' or only 'mildly painful'. The same number reported they would prefer to have local anaesthesia again in the event of their requiring a similar operation on their hand. We believe carpal tunnel release using local anaesthetic and a forearm tourniquet is well tolerated by the patient.
