Exclusion criteria
Exclusion criteria: 1.American Society of Anesthesiologists (ASA) Physical Status classification of IV or V. 2.Scheduled for emergency surgery. 3.Anticipated difficult airway based on preoperative assessment. 4.Known allergy or hypersensitivity to propofol, remifentanil, cisatracurium besylate, or dexamethasone, as required by the study protocol. 5.Planned use of inhaled anesthetic agents or combination with other anesthetic techniques (e.g., neuraxial anesthesia, nerve blocks) during the procedure. 6.Pre-existing neurological disorders (e.g., epilepsy, autism spectrum disorder, history of cognitive dysfunction), autonomic nervous system diseases, severe cardiac arrhythmias, or chronic pain unrelated to the lumbar pathology. 7.History of alcohol abuse, substance use disorder, or hearing impairment. 8.Requirement for anticholinergic medication before and/or during the study period. 9.Surgery anticipated to require deliberate hypotensive anesthesia where the target blood pressure would meet criteria for hypotension. 10.Surgery for oncological resection or due to active infection. 11.Any other condition deemed by the investigator to render the patient unsuitable for participation in this clinical study.
