An anesthesiologist who has not participated in the project, through the list of eligible patients who gave informed consent and the sequence of randomization blocks in a ratio of 1:1 will assign patients to one of the two groups of lidocaine or placebo, Blinding description: This study is double-blind. The patient and the evaluator (trained medical student) who conducts the interview are unaware of the treatment groups. The drugs will be prepared in similar syringes by the anesthetist technician, who is not aware of the plan's goals and will be provided to the anesthesiologist so that the difference between the two cannot be identified. The responsible anesthetist technician present in the operating room is aware of the groups so that in case of complications, he will provide the necessary information for the anesthesiologist to perform the necessary intervention. 3 Effect of intravenous lidocaine on awareness during general anesthesia for elective cesarean section. Intervention 1: Intervention group: In the lidocaine group, before induction of anesthesia, 1 milligram per kilogram intravenous lidocaine 2% (100 milligram/5 milliliter, Aburaihan Pharmaceutical Company, Iran) will be injected. Intervention 2: Control group: In the placebo group, the same volume (1 milligram per kilogram) of normal saline will be injected. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is not decided yet.
