Peri- and postoperative pain valutation in carpal tunnel release of median nerve compression

We analysed 108 patients, operated on day surgery, for carpal tunnel release of median nerve compression, to evaluate peri- and postoperative pain. We made in all cases a short intertenarian incision (25 mm) with microsurgical technique and local anaesthesia using mepivacaine 2% without vasoconstrictor. We evaluatedpain for local anaesthetic infiltration as VRS (Verbal Rating Scale) 6,3 median-time to the first possible analgesic assumption (in all cases paracetamol 500 mg), total analgesic assumption, algometry (to evaluate “allodiny”) after the first 48 hours and subjective pain intensity by a numerical pain scale. Pain intensity on first drug assumption (after a mean time of 7 hours from the end of surgery) had a mean VAS value of 2,15; while after a second pressure assumption of analgesic (after a mean time of 15 hours from surgery) had a mean VAS value of 2. Mean total analgesic assumption was 1,64 tablets of paracetamol 500 mg. From these data we may deduce that peri- and postoperative pain following median nerve decompression with this technique and anaesthesia, has a moderate intense peak of brief duration, for local anaesthetic infiltration (that seems to be the most painful event) and modest and not constant pain in the postoperative time (more evident 7 and 15 hours from the end of surgery). It may be useful association with mepivacaine bicarbonate solutions or injecting less painful local anaesthetic.
