This study was carried out to determine the effect of virtual reality glasses on reducing pain during vascular access in children. The study consisted of 70 children (35 children in the virtual reality video group and 35 children in the control group). Ethics committee approval, permissions from institutions and informed voluntary consent of the children were obtained in order to conduct the study. The data of the study were collected with Child Descriptive Characteristics Form, Parent Descriptive Characteristics Form, Visual Analog Scale (VAS), Revised Facial Expression Pain Scale (FPS-R), Intervention Monitoring Form, Child Behavior Observation Form and Parent Behavior Observation Form. In the study, the children in the experimental group were shown a video with virtual reality glasses during the vascular access procedure. Before and after the study; The child and his parents were asked to evaluate the pain experienced/will experience during the procedure, the children's heart rate, O2 saturation, body temperature were measured, and the behaviors of the child and the parent during the procedure were evaluated. A p value of <0.05 was considered statistically significant in data analysis.

This randomized controlled experimental study was conducted to determine the effect of virtual reality glasses on reducing pain during vascular access in children. The study was conducted among children aged 7-12 years in a tertiary hospital. Children in the experimental group (n=35) and control group (n=35); Age, gender, class of education, previous hospitalization and vascular access experience criteria were selected similar (p>0.05). Data were collected with Child Descriptive Characteristics Form, Parent Descriptive Characteristics Form, Visual Analog Scale (VAS), Revised Facial Expression Pain Scale (FPS-R), Intervention Monitoring Form, Child Behavior Observation Form, and Parent Behavior Observation Form. In the study, the children in the experimental group were shown a video with virtual reality glasses during the vascular access procedure. Before and after the study; The child and his parents were asked to evaluate the pain experienced/will experience during the procedure, the children's heart rate, O2 saturation, body temperature were measured, and the behaviors of the child and the parent during the procedure were evaluated. Data were used post-power analysis, descriptive statistics, Shapiro Wilk, Pearson chi-square, Mann Whitney U and Two-Related-Samples Tests. A p value of <0.05 was considered statistically significant in data analysis.
