Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Primary Outcome - Incidence of trigeminal cardiac reflex
Defined as a decrease in heart rate \>20% from baseline during surgery.
3 hours
Secondary Outcomes (3)
Time interval between Analgesia Nociception Index drop and subsequent heart rate decrease (early warning window).
3 hours
Total intraoperative opioid consumption.
3 hours.
Incidence of hypotension or arrhythmias.
3 hours
Study Arms (2)
Group A (Control Group
Standard monitoring including heart rate, non-invasive blood pressure, oxygen saturation, and bispectral index (BIS).
Group B (ANI Group)
Standard monitoring plus continuous ANI monitoring, with intraoperative analgesia adjusted to maintain Analgesia Nociception Index ( ANI) values between 50 and 70
