The participants in this group were started to watch videos by wearing virtual reality glasses about 2 minutes before the catheterization process was started and the process was continued until the end. Then, catheterization was performed by detecting the tourniquet by the emergency department nurse. Upon completion of the catheterization procedure, VRG was removed from the procedure area by the researcher. This process took an average of 5 minutes. After the procedure was completed, the pain and satisfaction status of the patients were scored on the VAS by the same nurse.

1 minute before starting the catheterization procedure in this group, a cold and vibration application was placed in the operation area by the researcher using the apparatus of the Buzzy ® device and started. The procedure was performed after evaluating the vein and determining the appropriate right or left arm. At the end of this time, the Buzzy ® has been shifted approximately 5 cm above the processing zone. Then, catheterization was performed. Upon completion of the catheterization procedure, Buzzy ® was removed from the procedure area by the researcher. This process took an average of 4 minutes. After the procedure was completed, the pain and satisfaction status of the patients were scored on the VAS by the same nurse.

Peripheral intravenous catheterization was performed by the same emergency department nurse in accordance with the procedure. The process took an average of 3 minutes. There was no application to the patients in the control group except for the standard procedure. After the procedure was completed, the pain and satisfaction status of the patients were scored on the VAS by the same nurse.

Group 1

In the study, Visual Analog Scale (VAS) was used to evaluate the pain of the patients. There is a 10 cm ruler on this scale. Patients were asked to rate the pain felt during the procedure on a 10 cm ruler. This scoring was done with a number between 1 and 10. The patient gave a score of "0" if he does not feel pain and "10" if he feels unbearable pain. After the completion of the procedure, the patients were asked to rate the pain they felt during catheterization on a visual comparison scale. At the end of the research, the scale results will be compared and evaluated for all three groups.

In the study, another visual comparison scale was used to determine the satisfaction levels of the patients regarding the application to be made. After the completion of the procedure, the patients were asked to rate their satisfaction with the procedure on the Visual Analog Scale (VAS). The scale was scored between 1 and 10, "0" was evaluated as ''I am not satisfied at all'', "10" was evaluated as ''I am very satisfied''. At the end of the research, the scale results will be compared and evaluated in three groups.
