Interest of virtual reality hypnosis in the EP lab in clinical practice : an observational study (Preprint)
UNSTRUCTURED Aims: Virtual reality Hypnosis (VRH) has been used successfully in different clinical settings to treat anxiety and the sensation of pain. We aimed to investigate the feasibility and safety of VRH in patients undergoing electrophysiology and stimulation procedures under conscious sedation. Methods: During a two-month period, VRH support was proposed to patients undergoing interventions. Data were compared with a control group (n=61) enrolled during the following three-month period. In the intervention group (n=25), the dedicated VR hypnosis programme was projected during the procedure. In both groups, pain and comfort were measured at the end of the procedure and at discharge, using visual analogue scales (VASs; 0-10). Results: Baseline characteristics were comparable in both groups. There was no difference in procedure duration (46 (±29) vs 56 (±32) min, p=0,18) nor in hypnotic / antalgic consumption (1.95 (±1.44) vs 2.00 (±1.22) mg, p=0,83 and 3.78 (±2.87) vs 3.58 (±2.48) μg, p=0,9) for the control and VR groups respectively. In a multivariate analysis, the use of VR was independently associated with lower comfort during the procedure, assessed by post-operative VAS (OR 15.00 (IC95%4.77;47.16), p<0.01). There was no influence of VR use on pain or drug consumption. Conclusions: In our experience, VR hypnosis in the EP lab doesn’t improve comfort during the procedure, compared to conventional human care. It has no influence on pain or drug consumption.
