Impact of Dexmedetomidine Versus Propofol on Intracranial Pressure in Adult Traumatic Brain Injury Patients: Randomized Controlled Double-Blind Trial

To investigate whether dexmedetomidine or propofol is more effective in controlling intracranial pressure (ICP) (assessed via optic nerve sheath diameter "ONSD" as a primary outcome) and which is more effective in suppressing lipid peroxidation (measured via malondialdehyde "MDA" as a secondary outcome). This double-blind randomized controlled trial aims to bridge this research gap by evaluating the biochemical neuroprotective efficacy alongside the clinical outcomes of both agents in TBI patients.
