Impact of Virtual Reality Distraction on Pain and Anxiety for Bedside Abdominal VAC Dressing Change

Not Applicable

Completed

• Conditions: Pain; Anxiety; Satisfaction, Patient
• Interventions: Device: VRD in addition to standardized analgesic protocol

• Registration Number: NCT04472416
• Lead Sponsor: University of Lausanne Hospitals

Brief Summary

We aim to study the use of a virtual reality device (VRD) in addition to our standardized analgesic care protocol for abdominal bedside VAC dressing change and we hypothesize to decrease pain and anxiety and to increase patients' comfort by this intervention.

Detailed Description

Monocentric non-blinded superiority randomized controlled trial: standardized analgesic protocol + virtual reality device vs. standardized analgesic protocol alone for abdominal VAC dressing change.

The day of the procedure, each patient will receive a standardized local and systemic analgesia 30 minutes before starting the procedure. The referring surgeon will explain at this moment every step of the procedure of bedside abdominal VAC dressing change.

Baseline levels of pain and anxiety will be assessed by use of VAS (0-10) and one additional questionnaire (STAI).

Virtual reality device will be activated 15 minutes before the beginning of the procedure and will remain as long as the procedure is going on and for 15minutes after finishing the wound dressing.

15 minutes after removing the VRD and 30minutes after finishing the wound dressing the STAI questionnaire and VAS for anxiety, pain and satisfaction (0-10) will be completed by the patient.

Arm && Interventions

Group	Intervention	Description
VRD + standardized analgesic protocol	VRD in addition to standardized analgesic protocol	Abdominal VAC dressing change using standardized analgesic protocol + virtual reality device

Primary Outcome Measures

Name	Time	Method
Change of pain using a virtual reality device in addition to a standardized analgesic protocol for bedside abdominal VAC dressing change. Pain will be measured by using a visual analogue scale (VAS) for pain (0-10) in the two groups.	Baseline (pre-procedure) and immediately after the procedure	Measurement of pain using a visual analogue scale (VAS) for pain with scores range from 0 (no pain) and 10 (worst possible pain), before (baseline: pre-procedure) and immediately after bedside abdominal vacuum assisted closure (VAC) dressing change in the two groups (virtual reality device + standardized analgesic protocol and standardized analgesic protocol alone) in order to demonstrate if a virtual reality device can reduce pain when used in addition to standard care.

Secondary Outcome Measures

Name	Time	Method
Change of anxiety using a virtual reality device along with a standardized analgesic protocol for bedside abdominal VAC dressing change. Anxiety will be measured by using, in the 2 groups, a VAS scale for anxiety along with a STAI questionnaire.	Baseline (pre-procedure) and immediately after the procedure	Measurement of anxiety using the validated questionnaire State Trait Anxiety Inventory (STAI) and a visual analogue scale (VAS) for anxiety from 0 (no anxiety) and 10 (worst possible anxiety), before (baseline: pre-procedure) and immediately after bedside abdominal vacuum assisted closure (VAC) in dressing change in the two groups (virtual reality device + standardized analgesic protocol and standardized analgesic protocol alone) in order to demonstrate if a virtual reality device can reduce anxiety used in addition to standard care.
Assessment of patients satisfaction using a virtual reality device in addition to a standardized analgesic protocol for bedside abdominal VAC dressing change. Satisfaction will be measured by using a visual analogue scale (VAS) for satisfaction.	Immediately after the procedure	Satisfaction assessment using a visual analogue scale (VAS) from 1 (not satisfied at all) to 10 (very satisfied) in the two groups (virtual reality device + standardized analgesic protocol and standardized analgesic protocol alone) in order to demonstrate if a virtual reality device can increase patients satisfaction when used in addition to standard care. The assessment will be performed immediately after the procedure.
