Intranasal Versus Intravenous Dexmedetomidine for Hypotensive Anesthesia in FESS

Intranasal Premedication With Dexmedetomidine Versus Intravenous Dexmedetomidine for Hypotensive Anesthesia During Functional Endoscopic Sinus Surgery in Adults: A Randomized Triple-Blind Trial

Intranasal dexmedetomidine provided good pharmacokinetic profile. However, intravenous dexmedetomidine have been used in functional endoscopic sinus surgery for several outcomes, there is lack in studies that had compared the efficacy of intravenous and Intranasal Dexmedetomidine for improving quality of the operative field in functional endoscopic sinus surgery.

Therefore, we established this randomized study to compare intranasal dexmedetomidine with intravenous dexmedetomidine improving quality of the operative field in functional endoscopic sinus surgery.
