      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: After referral of patients for elective Laparoscopic Cholecystectomy and evaluation of inclusion criteria and removal of patients who have exit criteria, they are divided into 2 groups using randomized block assignment (Permuted block randomization). The first group received an Opioid free anesthesia and the second group received a routine anesthesia (with Opioid), Blinding description: After admitting the patients, the Anesthetist's Assistant assesses them in terms of Inclusion Criteria and Exclusion Criteria., and then the Volunteers are selected from among them, and after obtaining Informed Written Consent from them, they are enrolled in the study without knowing the group in which they are placed. The Code assigned to each participant will be the order of Admission time. The position of each Code in the two groups is determined by the Statistics Consultant (Before commencing the admission of patients). The Anesthetic process is performed by the Senior Assistant and the Researcher does not play a direct role in the anesthetic process. Patient evaluators are different in the Operating Room and Recovery Room and Post-Surgical Ward, and are unaware of the anesthetic method. By doing this, Double-blind study method is provided.</study_design>
