      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Simple individual randomization with random allocation with envelopes in 2 groups A and B . In this method, we selected a number of cards or letters as an intervention group and the same ‎number of cards for the control group, then the cards were merged. One card was taken out and its ‎allocation was registered and the card was returned to the other cards after leaving. Then the cards ‎are merged again and we remove another card. This process continues to reach a random sequence ‎according to sample size, Blinding description: Outcome assessor and data analyzer and participant are blind (double blind). Outcome assessor and data analyzer and participant don't aware from grouping. The intern is unaware of the drugs prescribed in each group and the anesthesiologist prepares the drugs and provides them to the intern. Also, the patients do not know about their group.The syringes are covered with foil.</study_design>
