Correction: Implementation of the enhanced recovery after bariatric surgery (ERABS) protocol with clinical hypnosis: effects on pain and postoperative nausea and vomiting (PONV) management in bariatric surgery

Introduction Obesity is a major global health issue requiring tailored anesthetic and analgesic strategies due to associated
physiological and pharmacokinetic changes. The Enhanced Recovery After Bariatric Surgery (ERABS) protocol has been
introduced to optimize perioperative care, but its implementation remains inconsistent. This pilot study investigates the integration
of a perioperative clinical hypnosis (CH) protocol with ERABS to assess its effects on postoperative pain, nausea,
and analgesic/antiemetic drug consumption in patients undergoing bariatric and metabolic surgery (BMS).
Materials and methods A total of 42 patients undergoing elective gastric bypass were enrolled and divided into two groups:
one receiving standard ERABS protocol plus CH (Group A) and the other receiving only ERABS (Group B). Pain levels,
nausea, and medication use were assessed at 12 and 24 h post-surgery.
Results Results showed a significant reduction in pain in the CH group at both 12 h (mean NRS: 2.9 vs. 5.8, p = 0.0007)
and 24 h (mean NRS: 1.4 vs. 3.3, p = 0.0019). CH also led to a reduction in rescue analgesic use at 12 h (p = 0.05), though
no significant differences were found at 24 h. Postoperative nausea and vomiting incidence was lower in the CH group but
did not reach statistical significance.
Conclusions These findings suggest that perioperative CH could be a valuable adjunct to ERABS, improving postoperative
pain management and reducing analgesic consumption in the first 12 h post-surgery. Given the study’s limitations, including
small sample size and single-center design, further multicenter trials are recommended to confirm these preliminary results
and explore the underlying mechanisms of CH in surgical recovery.
