Intervention 1: Intervention group: It is an intravaginal anesthetic drug for induction of anesthesia or sedation that can be used for a short therapeutic course, such as insertion of shoulder joint or tracheal intubation. Its metabolism is essentially carried out with steroid hydrolysis to inactive metabolites, which are then excreted in urine and bile. The duration of the effect period is linearly dependent on the dose, which results in anesthesia with about 0.1 mg / kg per 100 seconds. Intervention 2: Control group: Propofol is a drug from the family of alkaline phenols, which was discovered in the 1970s. Propofol is used in general anesthesia for induction of anesthesia and maintenance of anesthesia in the intensive care unit, and an outpatient outpatient treatment is used in adults with a dose of 1.5-5.5mg / kg / 1 intravenously. Also, side effects of the medicine include the treatment of cholestasis and stroke epilepsy.
