Thyroid surgery under hypnosis: A 50-case series.

Objectives: The study objective was to compare patient satisfaction after thyroid lobo-isthmectomy under hypnoanesthesia versus general anesthesia.

Methods: A retrospective study included 100 patients undergoing lobo-isthmectomy. A group of 50 patients under hypnoanesthesia was compared to a control group of 50 patients under general anesthesia. Satisfaction was assessed on questionnaire between three and six months after surgery. We also compared secondary criteria: procedure time, blood loss, intraoperative comfort, postoperative pain, postoperative complications and time to resumption of daily activities.

Results: Our study showed good overall satisfaction in patients operated under hypnoanesthesia, for equivalent operative safety and complications rate compared to general anesthesia. For comparable analgesia, postoperative pain was lower, but not significantly, in the Hypnosis group, while the rate of nausea and vomiting was significantly lower (p<0.05). Postoperative convalescence was shorter in the Hypnosis group: 3.7 versus 9.2 days (p<0.001).

Conclusion: In thyroid surgery, hypnoanesthesia has real advantages over general anesthesia in that it places the patient at the center of the care team's attention. His or her active participation is essential during the process, bringing a new dimension to care, beneficial for the patient. However, it must be reserved for minimally invasive procedures in which organization is anticipated in full collaboration within teams that are willing and experienced.
