The proposed randomized controlled study will be conducted in the Department of Anaesthesia at Command Hospital (Air Force) Bengaluru. This study will be conducted on the patients undergoing lumbar surgeries under General Anaesthesia over a period of 18 months after approval from the Institutional ethical committee. Patients will be explained in detail regarding the study in their vernacular language and written informed consent will be obtained from them. All the 90 patients will be randomized using a computer-generated algorithm and concealment done using opaque sealed envelope into two groups with 45 patients in each group [n=45]. Group D patients will be receive Desflurane as the anaesthetic agent for maintenance of anaesthesia and Group P patients will receive Propofol as the anaesthetic agent for maintenance of anaesthesia. Demographic and clinical data including age, sex, height, weight, etc. will be recorded for all the patients. American Society of Anesthesiology (ASA) physical status, comorbidities and medications, if any will be noted. Recovery in the postoperative period will be compared in both the groups using "Modified Aldrete Score" which will be recorded at 10, 20 and 30 minutes after extubation in the post anaesthesia care unit. Comparing desflurane and propofol as an anaesthetic agent in spine surgeries can provide valuable insights into optimizing anesthetic plans, tailoring them to the specific demands of extended surgical procedures and ultimately contributing to enhanced patient care.
