Effect of Intraoperative Esmolol Infusion on Haemodynamics and Surgical Field in FESS Under General Anaesthesia

Abstract

Introduction: Functional endoscopic sinus surgery (FESS) is a commonly performed operation. Endoscopic sinus surgery allows enhanced illumination and visualization and it has dramatically improved surgical dissection. However major complications such as excess bleeding and poor visibility can arise do to work in a confined space.Due to poor visibility longer time to perform the surgery may arise. Material and Methods: This study was performed on randomly selected 60 patients, in a randomized placebo controlled double blind prospective study. We evaluated the hypotensive efficacy of intravenous Esmolol in FESS, reduction in blood pressure and Quality of surgical field and complications under general anaesthesia. Conclusions: Esmolol produces a lower surgical bleeding scores and better quality of operative field for the surgeon as well as less adverse effects.
