Conditions

The study focuses on sudden hemodynamic responses — increased blood pressure and heart rate — caused by skull-pin fixation during general anesthesia in posterior cervical spine fusion surgery..

Interventions

Intervention 1: Intervention group: the intervention group will receive 1 microgram per kilogram of bodyweight of intranasal dexmedetomidine in each nostril 30 minutes before the induction of anesthes

Design outcomes

Primary

MeasureTime frame
This randomized clinical trial investigates the effect of intranasal dexmedetomidine on hemodynamic responses during skull-pin fixation in posterior cervical spine surgery under general anesthesia. Timepoint: Hemodynamic variables will be measured at baseline, after intranasal drug administration, before and after skull-pin fixation, and every three minutes until surgical incision. Method of measurement: Blood pressure, heart rate, and oxygen saturation will be measured using standard operating room monitoring devices: non-invasive blood pressure (NIBP), electrocardiography (ECG), end-tidal CO2 (ETCO2), and pulse oximetry.
