Received Accepted Published Abstract Background Nowadays increasingly more preemptive analgesia studies focus on postoperative pain however the impact of preemptive analgesia on perioperative opioid requirement is not well defined. This study was carried out in order to evaluate whether preoperative intravenous flurbiprofen axetil can reduce perioperative opioid consumption and provide postoperative analgesia in patients undergoing thyroid gland surgery. Methods Ninety patients undergoing elective thyroid gland surgery were randomly assigned to three groups. Group A Control was administered Intralipid 2 ml as a placebo 15 min before the cervical plexus block and at the end of the surgery Group B Routine analgesia was administered a placebo 15 min before the cervical plexus .
