A virtual reality headset was placed on the heads of the individuals included in the intervention group one minute before the procedure and a cold environment image called "Peaceful mountain snow" was shown. By starting the image before the procedure, the individual was prevented from seeing the needle and blood. At the end of the procedure, the tourniquet and needle were removed and the virtual reality headset was removed from the individual's head and the displayed image was terminated.

A virtual reality headset was placed on the heads of the individuals in the placebo group one minute before the procedure and a warm environment image called "Deep space relaxation" was shown. By starting the image before the procedure, the individual was prevented from seeing the needle and blood. At the end of the procedure, the tourniquet and needle were removed and the virtual reality headset was removed from the individual's head and the image shown was terminated

No intervention was performed on the control group before the peripheral intravenous catheterization procedure, and the standard peripheral intravenous catheterization procedure was performed.

In this study, Sony playstation VR (Virtual Reality) glasses with LCD (Liquid Crystal Display) screen with OLED (Organic Light-Emitting Diode) technology and 1080P resolution integrated on the device were used. These glasses work integrated with the processor box. The processor box, which provides communication with the Sony playstation VR glasses, can also be connected to the computer with HDMI (High Definition Multimedia Interface) output. Within the scope of the study, the licensed "Peaceful mountain snow" image was shown. This image includes a cold winter day.

Following the completion of every VR session, the removable face pad was replaced and the goggles and headsets were wiped down with alcohol-based sanitary wipes. Preventing infection via the sharing of the technology was a paramount issue with the study patients.

The VAS is a 100 mm (10 cm) ruler that can be used horizontally or vertically. The value of "0" at the starting level defines painlessness, and the value of "10" at the ending level defines the most severe pain. The individual marks the intensity of pain they experience on this scale. In this study, the score measurements were determined in centimeters (cm) on the VAS prepared vertically to determine the intensity of pain experienced by individuals during phlebotomy application.individuals.during the procedure. One end indicated lack of pain and the other the most.Pain intensity was evaluated in centimeters.severe pain possible. Pain severity was evaluated in millimeters.

The inventory is in the form of a 4-point Likert scale, and the items in the State and Trait Anxiety Subscales are marked according to the degree of severity of the emotions and behaviors. There are ten items in the State Anxiety Scale and seven items in the Trait Anxiety Scale that contain reversed statements.

Body mass index normal weight (18.5-24.9 kg/m2)

The average value of the pressure pain threshold, which is defined as the point of pain.from three measurements taken at 5-second intervals from the elbow region of the left upper extremity where no intervention was performedperception and can vary from person to person, is between 8-16 Lb
