NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Interest of virtual reality hypnosis in the EP lab in clinical practice : an observational study
ABSTRACT
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.
