[Preemptive analgesic efficacy of gabapentin and nimesulide in the functional endoscopic sinus surgery].

Objectives: Preemptive analgesia is an important factor in controlling the postoperative pain and avoiding the stress response caused by the surgery. We aim to compare impact of gabapentin and nimesulide on postoperative analgesic consumption on the visual analog scale (VAS) as well as any potential side effects, to those of the placebo group.

Methods: Ninety patients aged 18-70 under ASA I-II risk, who were to undergo Functional Endoscopic Sinus Surgery (FESS), were included in the study. Patients were randomized into three groups. One hour before the surgery, oral placebo capsules were administered to Group I patients, Gabapentin 1200 mg to Group II patients and Nimesulide 100 mg to Group III patients. Perioperative hemodynamic parameters were measured for all patients. During the first 24 hours of the postoperative period, side effects such as nausea, vomiting, hypotension, hypertension, bradycardia, tachycardia were noted, and the time from end of the surgery to the first diclofenac need was recorded in addition to VAS scores.

Results: In all of the follow-ups for 24 hours of the postoperative period, time from end of the surgery until the first diclofenac requirement; Group 2 > Group 3 > Group 1. Total diclofenac consumption of group 2 was found to be significantly lower than Group 1 and Group 3 on a statistical basis. Postoperative VAS score in Group 2 was lower than Group 1 and Group 3.

Conclusion: To conclude, we believe that gabapentin or nimesulide may be safely used preemptively for the purposes of postoperative analgesia after FESS procedures.
