Remifentanil is widely used as intraoperative analgesic. Post infusion hyperalgesia has been documented experimentally in both animal and human volunteers. Gabapentin has anti-hyperalgesic effect.
To evaluate the effect of single preoperative oral dose of 300 mg gabapentin in attenuation of postoperative hyperalgesia induced by remifentanil and the decrease in post-operative analgesic requirement.
PATIENT AND METHOD:
A prospective randomized clinical trial conducted in Tikrit teaching hospital/ Iraq, at 2013. It involves 60 patients who underwent appendectomy. All patients were randomly allocated into two equql groups (each of 30 patients): First controlled group (CG) didn’t pre-medicated with gabapentine and 2nd gabapentine group (GG) pre-medicated with gabapentin.
Intraoperative infusion of remifentanil was used & postoperative pain was assessed in all cases.
The numerical analog scale NAS score and analgesia requirement post operatively was significantly higher in most times in the (CG) as compared with those of the (GG).
Premedication with 300mg gabapentin orally decreased hyperalgesic effect induced by remifentanil and so decreased the pain score and the analgesic requirement postoperatively.
