Nerve block using local anesthetic and dexmedetomidine in patients undergoing functional endoscopic sinus surgery

Abstract

Abstract Background The main anesthetic goal in the postoperative period of functional endoscopic sinus surgery (FESS) is early and pain-free recovery, with return of protective airway reflex. The aim of this study is to evaluate the role of dexmedetomidine as an adjuvant to regional blocks in patients undergoing functional endoscopic sinus surgery. Results Group bupivacaine + dexmedetomidine (BD) showed statistically significantly lower postoperative pain measurements than group bupivacaine (B), longer time to the first request of rescue analgesia, less patients needing rescue analgesia, and less rescue morphine analgesic requirements. Other measurements were insignificantly different between both groups. Conclusions Dexmedetomidine can be used as an adjuvant to regional nerve block in patients undergoing functional endoscopic sinus surgery. It effectively prolonged postoperative analgesia, decreased postoperative opioid analgesic requirements, and reduced the number of patients needing rescue analgesia.
