Comparison of Propofol and Propofol-Ketamine Anesthesia on Optic Nerve Sheath Diameter in Endovascular Cerebral Aneurysm Procedures
Abstract
This study aimed to compare the effects of propofol-based anesthesia and propofol-ketamine anesthesia on optic nerve sheath diameter (ONSD) in patients undergoing elective endovascular treatment of unruptured intracranial aneurysms. ONSD, measured using ultrasonography, is a non-invasive surrogate marker of intracranial pressure. In addition, intraoperative hemodynamic parameters, cerebral oxygenation, and anesthetic requirements were evaluated to assess the safety and physiological impact of the two anesthesia techniques.
