Abstract
Background: An important requirement during functional endoscopic sinus surgery is to maintain a clear operative field to improve visualization during surgery and to minimize complications.Aims: To evaluate Performance of functional endoscopic sinus surgery with isoflurane anesthesia.Methodology: 40 patients of either sex in the age group between 20-45 years with ASA grade I or II physical status who underwent functional endoscopic sinus surgery (FESS) under general Anaesthesia were provided hypotensive Anaesthesia (Group I) with isoflurane to facilitate bloodless operative field. The MAP was maintained between 55-60 mmHg. Another group of similar 40 patients were provided normotensive Anaesthesia and acted as control (Group II).Results: The mean duration (min.) of surgical procedure was lesser (p< 0.05) in group I that is 94.9 min as compared to 133.2 in group II. Similarly mean blood loss (ml) was considerably lower in group I (140 vs 255) than group II. Four patients of group II required blood transfusion whereas only one in group I. Surgical postponement was lesser in group I that is 2 as compared to 8 in group II. The mean inspired isoflurane concentration required to induce hypotension was 3.8%. In group I intraoperative heart rate was lower (p< 0.05) and MAP was significantly lower (p< 0.01) compared to group II patients. No patients of group I had any postoperative complication due to intraoperative hypotension
