This study aims to evaluate the utility of Analgesia Nociception Index (ANI) monitoring as a predictive and preventive tool for TCR during septoplasty. By comparing standard anesthetic monitoring with ANI-guided analgesia, this research seeks to determine whether maintaining optimal autonomic balance can reduce the incidence of trigeminal cardiac reflex (TCR) and improve intraoperative cardiovascular stability.
