      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: Balanced (permuted) block randomization( four random blocks).
In each block, 4 patients are randomly assigned random codes A1, A2, A3 and B, and according to the corresponding code, they receive the dose and the desired drug or placebo, Blinding description: The normal saline serum containing medicine or placebo is prepared and coded by a nurse who is not aware of the study process. The prescriber and collaborator, who completes the relevant assessments and completes the questionnaire, is not aware of the drug or placebo received by the patient. After completion of the data collection work, analyzes will be carried out based on the relevant codes.</study_design>
