Then one of these envelopes is selected and the patient is placed by the anesthesiologist (who is not involved in the data collection and analysis) and the next three patients are determined on this basis and the desired intervention is performed in the recovery room by the anesthesiologist.

In this way, the subject is unaware of the contents of the syringes, which are identical in shape and quantity. The evaluator also measures clinical and diagnostic measurements using coding that is unknown to him/her. 3 سنگ کیسه صفرا.
