What this trial studies

This is a multicenter, randomized, parallel-group trial in three Moroccan hospitals that enrolls ASA I–II adults scheduled for abdominal surgery and randomizes them 1:1 to a 15–20 minute level 2 hypnosis session versus standard psychological preparation. Allocation is stratified by center and sex, and the primary outcome is visual analog scale (VAS) anxiety measured after the intervention, with secondary outcomes including postoperative VAS pain, analgesic consumption, and length of stay. The trial is powered to detect a 10 mm reduction in anxiety VAS with 80% power at α=0.05 and plans to enroll about 48–68 participants. Protocol support is linked to a PhD at Université Hassan 1er Settat.

Who should consider this trial

Good fit: Ideal candidates are consenting adults (ASA I–II) scheduled for abdominal surgery who can understand and follow instructions and have no major psychiatric or cognitive disorders.

Not a fit: Patients with prior hypnosis experience, active major mental illness, cognitive impairment, or current psychoactive substance use are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If effective, a short preoperative hypnosis session could reduce anxiety and postoperative pain, lower analgesic needs, and possibly shorten hospital stay.

How similar studies have performed: Previous randomized trials and meta-analyses have reported modest reductions in perioperative anxiety and pain with hypnosis, so this trial builds on supportive but not definitive evidence.
