Preoperative Gabapentine for Carpal Tunnel
Effect of Preoperative Gabapentine for Carpal Tunnel Syndrome
The purpose of this study was to evaluate the postoperative analgesic effect of preoperative gabapentine for carpal tunnel syndrome surgery.

There was studied 40 patients. Group 1 patients received 600 mg of gabapentin 1 hour before surgery; G2 received placebo 1 hour before surgery.

Anesthesia was regional intravenous block. Postoperative analgesia when needed was with acetaminophen. If needed was administered codeine. The evaluation of neuropathic pain was made by DN4 questionnaire. Pain intensity was assessed by numeric scale at block and after 30min, 1h, 2h, 2wk, 4wk, 6m. It was noted the duration of analgesia, and the amount of acetaminophen and codeine.

The statistical program used for analysis of the results was the Instat Graph
