Seoul I Plastic Surgery's sedation anesthesia is administered selectively at the physician's discretion to help patients undergo procedures with significant pain burden more comfortably.
Sedation anesthesia is not uniformly applied to all patients. Through pre-procedure medical evaluation, the physician comprehensively considers patient condition, procedure scope, pain level, past sedation history, and medication administration history to determine whether to proceed and the appropriate drug and dosage.
This hospital strictly manages psychotropic medications used for sedation anesthesia in accordance with relevant laws and safety management standards, and misuse of these medications is strictly prohibited. Since dependency and side effects may occur depending on the individual, the procedure must follow the physician's guidance. Sedation anesthesia may be restricted when there is concern of misuse or when deemed necessary for patient safety.
