Intervention arm receives 15-20 min level 2 hypnosis session preoperatively; control receives standard psychological preparation. Primary outcome: VAS-anxiety post-intervention. Secondary: postoperative EVA-pain, analgesic consumption, length of stay. Study Design Prospective, multicenter, parallel-group RCT (1:1 allocation, stratified by center/sex). Inclusion: consenting ASA I-II adults for abdominal surgery. Primary endpoint powered for 10mm EVA reduction (80% power, α=0.05).
