Postoperative Pain
Conditions
Brief summary
This study aims to determine whether goal-directed analgesia using ANI(Analgesia/Nociception Index) can improve the quality of postoperative recovery in patients undergoing maxillofacial surgery.
Interventions
intraoperative analgesia was provided by infusion of remifentanil via target controlled infusion mode, which was controlled according to ANI monitor.
intraoperative analgesia was provided by infusion of remifentanil via target controlled infusion mode, which was controlled according to the clinician's decision
