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.
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.
