The Effect of Virtual Reality on Pain Experienced by School-Age Children During Venipuncture: A Randomized Controlled Study.

Objective: The use of virtual reality (VR) as a non-pharmacologic method may enable children to tolerate invasive procedures in a hospital setting easily and feel less pain. This study aimed at determining the effect of using a VR headset during venipuncture on pain level, heart rate (HR), and oxygen saturation values in children aged 7-12 years old. Materials and Methods: This was a randomized controlled experimental study. This study included 102 children (experimental group: 52; control group: 50) who visited a pediatric outpatient clinic of a university hospital in Turkey between May 2018 and May 2019. Data were collected using the Child and Family Information Form, State Anxiety Inventory for Children, Faces Pain Scale-Revised (FPS-R). Before venipuncture, state anxiety and pain scores of the children were evaluated. The children in the experimental group wore VR headsets during venipuncture. The children in the control group underwent standard venipuncture procedure. Pain scores were evaluated again in both groups after the venipuncture. Before, during, and after the venipuncture, pulse and oxygen saturation values were measured. Results: It was determined that post-procedure pain score was 1.46 ± 1.49 in the experimental group and 4.44 ± 2.26 in the control group. Post-venipuncture pain mean scores were significantly lower in the experimental group than those of the children in the control group (Z = -6.574; P = 0.001). Secondary outcomes: The mean HR during the procedure was significantly lower in the experimental group (99.27 ± 18.34/min) than in the control group (108.20 ± 21.42/min) (P = 0.026; t = -2.265). There was no statistically significant difference between the before and after the procedure difference of oxygen saturation values (Experimental group: -0.15 ± 1.54; Control Group: 0.04 ± 0.93) between groups (Z = -0.023; P = 0.982). Conclusion: It was determined that post-venipuncture pain mean scores were significantly lower in the experimental group than in the control group. VR is effective to reduce the pain of children during venipuncture. VR headsets may be recognized as effective instruments to reduce the pain level of children in hospital settings.
