Comparison of Dexmedetomidine Versus Propofol Infusion in Functional Endoscopic Sinus Surgery (FESS) to Induce Controlled Hypotension in a Tertiary Care Centre

Abstract

Background: Functional endoscopic sinus surgery (FESS) is a commonly employed surgery 
in patients with rhinosinusitis. Intraoperative local bleeding is a major problem in this 
surgery. Controlled hypotension is a method by which arterial blood pressure is decreased in 
a deliberate but predictable manner to increase surgical field visibility. The aim of our study 
was to compare Dexmedetomidine and Propofol to induce hypotension and also to find out 
which is better. Material and Methods: A comparative study of Dexmedetomidine versus 
Propofol to induce controlled hypotension was done in 100 (GROUP D-50 patients given 
Dexmeditomidine, GROUP P-50 patients given Propofol) adult patients posted for FESS.  
Study was undertaken during January 2020 to September 2021 at Govt ENT hospital, Koti, 
Hyderabad after institutional ethical committee clearance, and informed consent from the 
patients.  Outcome compared among the two groups was vitals, quality of surgical field, 
blood loss and sedation score.
