Intraoperative Infusion of Either Lidocaine or Dexmedetomidine on Regional Cerebral Oxygen Saturation and Postoperative Delirium in Elderly Patients Undergoing Abdominal Surgeries
Sponsor: Tanta University
Summary
This study aims to compare the effect of intraoperative infusion of either lidocaine or dexmedetomidine on the incidence of postoperative delirium (POD) in elderly patients undergoing major surgeries. It also aims to evaluate the impact of both medications on intraoperative regional cerebral oxygen saturation (rSO₂).

Lidocaine
Patients will receive an IV bolus (50 ml) of lidocaine (1mg/kg) diluted with saline over 10 min before induction of anesthesia. This will be followed by intraoperative lidocaine infusion in a dose of 1.5mg /kg/hr till the end of surgery.
Dexmedetomidine
Patients will receive an IV bolus (50 ml) of dexmedetomidine in dose 0.5 μg/kg over 10 min before induction of anesthesia. This will be followed by intraoperative dexmedetomidine infusion in a dose of 0.3 μg/kg/hr till the end of surgery.
