Using Hypnosis and Virtual Reality During Pre and Postoperative Cardiovascular Surgery. (VRHypnICU)
The Influence of Non-pharmacological Medical Approaches Such as Hypnosis and Virtual Reality to Reduce Pain and Anxiety Before and After a Cardiovascular Surgery. A Randomized Study.
Nowadays, the use of cognitive behavioral therapies has become quite common in the clinical care. Different non-pharmacological techniques, including hypnosis and virtual reality are currently used as complementary tools in the treatment of acute and chronic pain (Pourmand et al., 2017; Vanhaudenhuyse et al., 2009). A new technique called 'virtual reality hypnosis' (VRH) (Patterson et al., 2004), which encompasses a combination of both tools, is regularly used although its actual function remains unknown to this date. With the goal to improve our understanding of VRH combination effects, it is necessary to elaborate randomized and controlled research studies in order to understand their actual function in individual's perception.
100 patients who are undergoing a cardiovascular surgery at the Liège University Hospital will be randomly assigned to four conditions (control, hypnosis, VR and VRH). Each participant will receive two sessions of one of the techniques: one the day before the surgery and one other session the day after, in intensive care units.
Physiological parameters will be taken and participants will fill in a questionnaire which evaluates their level of perceived immersion, their level of anxiety, fatigue, pain and relaxation. A short interview will also be conducted to give participants the opportunity to openly describe their experience.
This study will help to expand the knowledge regarding the influence of these techniques on patient's cognition, perception and sensation .

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control group
[Randomized] Patients in control group will receive regular nursing care but no behavioral therapy intervention.
|
|
Experimental: Hypnosis (Hypn)
[Randomized] Patients will receive a hypnosis recorded audiotape.
|
The hypnosis session will consist of a 20-minute hypnosis recording created by Marie-Elisabeth Faymonville and recorded by Anne-Sophie Nyssen, both professionals in hypnosis from University of Liège.
The recording includes suggestions about relaxation, corporal sensations, respiratory techniques and visual imaginative stimuli about a beautiful landscape.
With this tool, the hypnosis session is standardized for all patients and there is no need of a psychotherapist to deliver hypnosis.
|
Experimental: Virtual reality (VR)
[Randomized] Patients will see a 3D movie with a beautiful landscape.
|
VR sessions.
This session will consist in using a head-mounted 3D graphical display with goggles.
With this tool, participants will be able to visualize a 3D immersive landscape for 20 minutes consisting of a shed near a lake at sunrise followed by a relaxing moment in the clouds.
The session ends on the lake's edge.
|
Experimental: Virtual reality hypnosis (VRH)
[Randomized] Patients will see the same 3D film combined with a hypnotic voice.
|
The combined tool sessions.
Participants will be simultaneously subjected to the same hypnosis recording and 3D visual stimuli used in the Hypn and VR conditions.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Anxiety
Time Frame: Day-1 before surgery (T0 before intervention; T1 after intervention), Day+1 after surgery (T2 before intervention; T3 after the intervention)
|
Visual Analogical Scale (VAS) from 0 to 10.
This is a subjective linear scale.
No anxiety = 0, maximum anxiety = 10.
|
Day-1 before surgery (T0 before intervention; T1 after intervention), Day+1 after surgery (T2 before intervention; T3 after the intervention)
|
Pain perception
Time Frame: Day-1 before surgery (T0 before intervention; T1 after intervention), Day+1 after surgery (T2 before intervention; T3 after the intervention)
|
Visual Analogical Scale (VAS) from 0 to 10.
This is a subjective linear scale.
No pain = 0, maximum pain = 10.
|
Day-1 before surgery (T0 before intervention; T1 after intervention), Day+1 after surgery (T2 before intervention; T3 after the intervention)
|
Secondary Outcome Measures

|
Day-1 before surgery (T0 before intervention; T1 after intervention), Day+1 after surgery (T2 before intervention; T3 after the intervention)
|

Time Frame |
---|---|---|
Participant's tendency to be absorbed and dissociated
Time Frame: Day-1 before surgery (T0 before the intervention)
|
Dissociative Experience Scale (DES) 28-items (Beirnstein, 1986).
This scale measures the dissociative experiences someone can experiment in everyday life.
|

Absorption will be measured as the two components of hypnosis.
We will measure absorption and dissociation using the Visual Analogical Scales (VAS).
VAS is from 0 to 10. 0 is not absorbed and 10 is really absorbed.
When responding to a VAS item, participants will be asked to specify their level of agreement to a statement by indicating a position along a continuous line between two end-points.
