Role of Dexmedetomidine on Hemodynamics and Anesthetic Requirement in Patients Undergoing Elective Infratentorial Tumor Surgery: A Prospective, Randomized, Double-blind, Placebo-controlled Study

Key Points

• This research aims to evaluate the effects of dexmedetomidine on hemodynamics and anesthetic requirements during infratentorial tumor surgery.
• Prospective, randomized, double-blind, placebo-controlled design
• Administered dexmedetomidine infusion during surgery
• Compared hemodynamic stability and anesthetic usage between groups
• Dexmedetomidine infusion ensured stable perioperative hemodynamics
• Reduced isoflurane requirements during the procedure
• Decreased intraoperative fentanyl needs compared to placebo
