Abstract :

Back ground : To evaluate the effect of Dexmedetomidine infusion on the requirement of Isoflurane for controlled hypotension(MAP of 60–70mmHg), quality of bloodless surgical field, duration of surgery and the awakening time in patients undergoing FESS. Study design : A prospective ,randomised control study in 50 adult patients of either sex between 18 – 60 years of age . Patients are randomised and compared based on MAP, requirement of isoflurane percentage, duration of surgery,quality of operating field, awakening time into 2 groups ,Group D – Dexmedetomidine and Group C – control . The duration of surgery,awakening time and intraoperative isoflurane requirement was statistically low in Group D compared to group C . Conclusion : Dexmedetomidine infusion helps in achieving a targeted reduction in MAP, reduced intraoperative Isoflurane requirement, better blood less field, and faster awakening in patients undergoing FESS.
