Anesthesia Techniques, Neuroprotection and Surgical Field in FESS Under Controlled Hypotension
FUNCTIONAL ENDOSCOPIC NASAL AND SINUS SURGERY AND ANESTHESIA: Study of Hemodynamic Parameters During General Anesthesia Compared to the Surgical Field, as Well as Assessment of Cerebral Ischemia Intraoperatively by Measurement of S100B Protein and Specific Neuronal Enolase (NSE).

Conditions
Summary
This prospective, randomized controlled trial investigates the effect of four different anesthetic maintenance techniques on surgical field conditions, hemodynamic stability, and neuroprotection during functional endoscopic sinus surgery (FESS) performed under controlled hypotension. Patients are randomly assigned to receive either total intravenous anesthesia with propofol-remifentanil, propofol-remifentanil with adjunct ketamine and magnesium, sevoflurane-remifentanil, or sevoflurane-remifentanil with adjunct ketamine and magnesium. Primary outcomes include serum biomarkers of neuronal injury (S100B and neuron-specific enolase, NSE) measured perioperatively, as well as surgical field visibility and intraoperative bleeding scores. Secondary outcomes include recovery profile and postoperative pain.
