Insights
Virtual reality (VR) significantly reduced fear in children during intravenous procedures. While pain levels remained similar, VR showed potential as a supportive tool in pediatric nursing care.
Area of Science:
- Pediatric Nursing
- Medical Technology
- Psychophysiology
Background:
- Intravenous (IV) procedures in children often cause significant fear and discomfort.
- This distress can complicate procedure performance and patient experience.
- Supportive technologies are needed to mitigate fear during pediatric IV procedures.
Purpose of the Study:
- To investigate the efficacy of virtual reality (VR) as a supportive technology during pediatric IV procedures.
- To assess the impact of VR on children's fear and pain perception.
- To evaluate physiological responses, including autonomic nervous system activity, during IV procedures with VR.
Main Methods:
- A randomized, parallel-group study involving 50 children undergoing IV procedures.
- Participants were allocated to either a virtual reality group or a standard care comparison group.
- Fear and pain were measured via self-report; physiological data included heart rate variability, heart rate, and blood pressure.
Main Results:
- Children in the VR group reported significantly lower levels of fear compared to the control group.
- No significant differences in pain scores were observed between the VR and comparison groups.
- The VR group exhibited altered heart rate variability indices, indicating a less dominant sympathetic autonomic response, correlating with reduced fear.
Conclusions:
- Virtual reality demonstrates potential as an effective supportive technology for reducing fear in children during IV procedures.
- VR may offer clinical benefits in pediatric nursing by improving patient comfort and cooperation.
- Further research into VR's psychophysiological effects can optimize its application in healthcare settings.
Abstract:
Children undergoing intravenous procedures often experience substantial fear and discomfort, which can make these procedures more difficult to perform. This study examined whether virtual reality could serve as a supportive technology during pediatric intravenous procedures. A randomized, parallel-group design was used with 50 children assigned to either a virtual reality group or a comparison group. Pain and fear were assessed using self-report measures, and physiological responses were evaluated using heart rate variability, heart rate, and blood pressure indicators. Children in the virtual reality group reported significantly lower fear than those in the comparison group, whereas pain scores did not differ significantly between groups. The virtual reality group also showed significant differences in heart rate variability-related indices, suggesting a less pronounced sympathetic-dominant autonomic pattern, which may be clinically meaningful in the context of lower fear during intravenous procedures. These findings support the potential role of VR as a supportive technology in pediatric nursing care during intravenous procedures.
