Purpose: Minimally invasive parathyroid surgery and hypnosis are both increasing in prevalence. The objective of this study was to evaluate the efficacy of hypnoanalgesia compared with sedation during primary hyperparathyroid surgery under local anaesthesia.
Methods: All patients who underwent primary hyperparathyroid surgery under local anaesthesia in our department between January 2013 and April 2018 were included retrospectively in two groups: patients operated under hypnoanalgesia (HYP group), and patients operated under sedation (LA group). The evaluation criteria were postoperative pain and analgesic consumption, amount of perioperative anti-emetics required, and length of hospital stay.
Results: Thirty-six patients were included, 19 in the HYP group and 17 in the LA group. Postoperative pain levels and analgesic consumption rates were lower in the HYP group (numeric scale = 0.5/10 vs. 2.7/10, p = 0.0001; 11% vs. 47%, p = 4.9 × 10-8). Intraoperative anti-emetics delivery was lower in the HYP group (5% vs. 35%, p = 2.9 × 10-7). The ambulatory care rate was higher in the HYP group (74% vs. 59%, p = 0.03).
Conclusion: Local anaesthesia with hypnoanalgesia, compared with sedation during minimally invasive parathyroid surgery, improved early postoperative outcomes, making outpatient management more efficient.
