A small nonrandomized study found no drug-sparing advantage from virtual-reality hypnosis and reported lower comfort. That differs from assuming every VR intervention improves procedural experience.
The comparison
Twenty-five patients accepted VR-hypnosis support, and outcomes were compared with sixty-one patients treated during a later period. Both groups continued usual conscious sedation.
Midazolam and sufentanil amounts did not differ significantly. VR support was associated with lower reported comfort, while pain and medication consumption did not show a favorable effect.
A selected intervention and population
The study was retrospective, single-center, and nonrandomized, with substantial refusal and withdrawal. Expectations, selection, period effects, and human support could contribute. Small numbers also limited precision.
VR was not tested as a replacement for all sedation. The paper cannot establish that VR generally worsens care or that a nonsignificant dose comparison proves exact equivalence. It supports reporting the actual program, patient acceptance, comparator care, and distinct comfort, pain, and sedative-use outcomes rather than importing benefits from a different procedure or VR system.
