Brief Summary

This randomized controlled trial is designed to evaluate the efficacy of immersive virtual reality (VR) as an adjunct to standard analgesia during dressing changes in adult burn patients. The study compares an intervention group receiving standard care combined with an immersive VR distraction (using a head-mounted display displaying an engaging virtual environment) versus a control group receiving standard care plus non-VR distraction (watching a nature video on a tablet). The primary outcomes include procedural pain intensity measured by the Visual Analog Scale (VAS) and anxiety levels measured by the State-Trait Anxiety Inventory (STAI). Secondary outcomes include patient satisfaction and physiological parameters (heart rate and blood pressure) recorded during the procedure. This trial addresses the critical gap of heterogeneity and small sample sizes noted in previous VR studies for burn care pain management (Dascal et al., 2017).

Detailed Description

Procedural pain during dressing changes for burn wound care remains a substantial clinical challenge affecting both patient comfort and treatment compliance. Immersive VR technology has been suggested as an effective distraction technique, potentially reducing pain and associated anxiety by providing a highly engaging alternative sensory input. However, previous studies have been limited by variable protocols and modest sample sizes.

In this single-center RCT, adult burn patients aged 18-65 years with partial-thickness burns scheduled for routine dressing changes will be enrolled. Participants will be randomly assigned in a 1:1 ratio to either:

Intervention Group: Standard care (analgesia as per institutional protocol) plus immersive VR distraction (using a commercially available head-mounted display with interactive virtual environments) Control Group: Standard care plus non-VR distraction, operationalized as watching a nature video on a tablet device.

Randomization will be computer generated.

Outcome assessors will be blinded to treatment assignment. The primary outcome measures are procedural pain intensity (assessed using a 10-cm Visual Analog Scale immediately post-procedure) and anxiety (assessed using the State-Trait Anxiety Inventory immediately post-procedure). Secondary endpoints include patient-reported satisfaction with the distraction modality and objective physiological parameters (heart rate and blood pressure) monitored throughout the procedure.

Data will be collected at each dressing change session over the study period, and repeated measures analysis will be applied to assess between-group differences.

Study Groups

VR Distraction

Participants in this arm will receive standard analgesic care according to institutional protocols plus an immersive virtual reality (VR) distraction intervention. During each burn dressing change, participants will wear a head-mounted display delivering an interactive, engaging virtual environment specifically designed for distraction. This arm aims to assess the efficacy of VR in reducing procedural pain intensity and anxiety compared to the control condition.

Group Type: EXPERIMENTAL

Immersive Virtual Reality Distraction (IVRD)

Intervention Type: BEHAVIORAL

Intervention Description:

Participants assigned to this intervention will receive standard analgesic care per institutional protocol in addition to an immersive virtual reality (VR) distraction intervention. During each burn dressing change, participants will wear a head-mounted display (HMD) that delivers an interactive and engaging virtual environment designed specifically to distract from procedural pain and reduce anxiety. The VR session will last for the entire duration of the dressing change (approximately 10-15 minutes) and will be administered during every session. The VR system is calibrated to provide high levels of sensory immersion to effectively divert attention from painful stimuli.

Nature Video Distraction

Participants in this arm will receive the same standard analgesic care as the experimental group and will be provided with a non-VR distraction intervention. They will watch a nature video displayed on a tablet device during each burn dressing change session. This comparator is designed to control for the effects of distraction, allowing assessment of whether immersive VR provides additional benefit beyond conventional video distraction.

Group Type: ACTIVE_COMPARATOR

Nature Video Distraction (NVD)

Intervention Type: BEHAVIORAL

Intervention Description:

Participants in this intervention will receive the same standard analgesic care provided to all subjects and, in addition, will watch a nature video on a tablet device during the burn dressing change. The video distraction serves as an active comparator to the immersive VR. The nature video is selected to be calming and engaging, and it will be played continuously during the dressing change session (approximately 10-15 minutes). This intervention allows evaluation of whether immersive VR provides additional benefit in reducing procedural pain and anxiety over a standard video distraction.
