During peripheral intravenous catheterization, virtual reality headset (Oculus Go) will be worn. Because the headset is reusable, attention will be paid to disinfecting them before and after each use.

During peripheral intravenous catheterization, an audio clip Mp3 player and headphones will be worn. Since these headphones are reusable, they will be disinfected before and after each use.

No intervention will perform on the control group before the peripheral intravenous catheterization procedure, and the standard peripheral intravenous catheterization procedure will perform.

During the PIK application, 3D visual and audio videos of the beach will be played with an Oculus Go brand virtual reality (VR) headset until the procedure is completed. The video that starts at the beginning of the procedure is planned to last approximately 2-3 minutes during the application. During this time, patients will be asked to close their eyes and take a comfortable position. The VR headset will be disinfected after each application and used on the other patient.

In the stages of the peripheral intravenous catheterization intervention of individuals in the application and control groups, a chronometer will start immediately after an automatic tourniquet is attached to the patient's arm. After catheterization was completed successfully, the chronometer was stopped, and the procedure duration was recorded in the form of seconds on the data collection form.

A 10-cm vertical VAS was used to evaluate the severity of pain felt by the individuals during the procedure. The lowest score that can be obtained from the scale is 0 and the highest score is 10 cm (100 mm). Pain severity was evaluated in millimeters

A scale between 1 and 10 will be used to evaluate the patients' satisfaction levels with the procedure. "1" on this scale indicates the least satisfaction level, and "10" indicates the highest satisfaction level. Patients will be asked to mark their level.
