Not Applicable

• Conditions: Pain; Anesthesia; Surgery

• Registration Number: NCT03218306
• Lead Sponsor: University of Cagliari

Brief Summary

The study is aimed at confronting a surgical pleth index based protocol for intraoperative analgesia in a desflurane based general anesthesia for thyroidectomy, versus a standard clinical approach. A reduction in analgesic consumption and improvement in hemodynamics are expected.
