This study is comparing two types of anesthesia — sevoflurane (an inhaled anesthetic) versus propofol (an intravenous anesthetic) — to see which one causes less post-operative delirium (confusion and disorientation after surgery) in patients undergoing liver transplantation. **You may be eligible if...** - You are 19 years or older - You are scheduled to undergo a liver transplant - You will receive either sevoflurane or propofol anesthesia as part of your standard care **You may NOT be eligible if...** - You have hearing loss, significant cognitive impairment, or dementia - You have a diagnosed neurological disorder such as a history of stroke, brain hemorrhage, Parkinson's disease, or other conditions affecting the brain - You have hepatic encephalopathy (confusion related to liver failure before surgery) - You have difficulty communicating Talk to your doctor to see if this trial is right for you.
