What this trial studies

This clinical trial compares the effectiveness of hypnosis versus an equimolar mixture of oxygen and nitrous oxide (MEOPA) for pain management during bone marrow biopsies. The study aims to enhance patient comfort and reduce anxiety associated with this invasive procedure. Participants will be randomized to receive either hypnosis or MEOPA, with the goal of assessing pain perception and overall experience during the biopsy. The trial is multicenter, involving multiple hospitals in France, and seeks to provide evidence for a potentially less invasive and more effective method of analgesia.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are naive to bone marrow biopsy procedures and can provide informed consent.

Not a fit: Patients who require MEOPA for their procedure or have certain psychiatric conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve patient comfort and reduce anxiety during bone marrow biopsies.

How similar studies have performed: Previous studies have shown promising results for the use of hypnosis in reducing anxiety during invasive procedures, indicating potential for success in this approach.
