VR Based Simulation in the Preparation of Children for MRI - MRVR

Not Applicable

Recruiting

• Conditions: Anesthesia; Children, Only
• Interventions: Other: VR; Other: Booklet

• Registration Number: NCT06132854
• Lead Sponsor: Semmelweis University

Brief Summary

The goal of this randomized controlled trial is to evaluate whether a virtual reality based preparation method can efficiently decrease the proportion of children requiring general anesthesia during MRI examinations.

Participants will take part in a virtual reality environment resembling an MRI before their scheduled MRI examination.

Researchers will compare these children to usual care and a booklet based preparation method to see if less children need anesthesia for completing the MRI examination.

Detailed Description

Study Description:

Our study investigates the efficacy of a custom-made virtual reality experience in the preparation of children for MRI examinations. We hypothesise that preparation with VR can significantly reduce the need for anesthesia in children during MRI examinations, or if anesthesia is needed less doses of anesthetics are required.

Objectives:

Primary Objective:

To evaluate whether the VR based preparation decreases the need for anesthesia and sedation during MRI examinations.

Secondary Objectives:

To evaluate whether fear, mood, anxiety, familiarity with the MRI examination of the children and willingness to take part again change as a result of the intervention.

Endpoints:

Primary Endpoint:

The need for any anesthetic or sedative medication during MRI examination.

Secondary Endpoints:

Visual analogue scales related to fear, mood and familiarity, willingness to take part in an MRI examination again.

Study Population: 288 children aged 4-18 years who are in- or outpatients at the Pediatric Center of the Semmelweis University and are scheduled for MRI examination with anesthesia will be enrolled.

Description of Sites/Facilities Enrolling Participants:

The study takes place in the two Departments of the Pediatric Centre of the Semmelweis University

Description of Study Intervention/Experimental Manipulation:

Our research will be conducted as a three arm randomized controlled trial (VR, booklet, usual care). Participants in the VR condition are immersed in a unique 360° VR experience specifically designed for this study.

Children in the booklet condition will be prepared by using an educational booklet containing colorful illustrations about the MRI examination.

In the usual care condition children are prepared by the healthcare staff without using any specific equipment or standardized methods.

Study Duration:

36 months

Participant Duration:

All participants need a single visit intervention to complete all study related tasks.

Arm && Interventions

Group	Intervention	Description
VR	VR	Participants in the VR group are immersed in a unique 360° VR experience specifically designed for this study. The custom made VR experience consists of two parts. In the first part, children find themselves in a simulated MRI room which resembles to the one they will be scanned. The second half of the VR experience introduces a mindfulness-ACT based meditation segment within the context of a space travel.
Booklet	Booklet	Children in the booklet condition will be prepared by using an educational booklet containing colorful illustrations of the MRI examination room and about the procedure. This serves as a resource to familiarize them with the MRI procedure, address common concerns, and provide information about what to expect during the exam. The role of the booklet condition is to serve as an active control for our experimental condition. This condition also contains an interaction with the experimenter and increases familiarity through explanation and illustrations. However, it does not involve the immersive effect of the VR.

Primary Outcome Measures

Name	Time	Method
proportion of children requiring anesthesia	during the MRI examination, assessed directly after the MRI from anesthesiology documentation	proportion of children requiring any form of anesthesia or sedation during the MRI examination

Secondary Outcome Measures

Name	Time	Method
fear	assessed directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination	fear of the child measured on a visual analogue scale range 1-100, higher indicating increased fear
nervousness	directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination	nervousness of the child measured on a visual analogue scale, scale range 1-100, higher increased nervousness
willingness to take part again	no later than 4 hours after the MRI examination	willingness of the child to take part in a future MRI examination measured on a visual analogue scale, scale range 1-100, higher indicating more willingness taking part in a future MRI examination
mood	directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination	mood of the child measured on a visual analogue scale, scale range 1-100, higher indicating better mood
familiarity	directly before the intervention, directly before the MRI examination, no later than 4 hours after the MRI examination	familiarity of the child with the MRI examination measured on a visual analogue scale scale range 1-100, higher indicating increased familiarity with the MRI
helpfulness	directly before the MRI examination	indication how much the child found the preparation method helpful, measured on a visual analogue scale, scale range 1-100, higher indicating the preparation method was more helpful
