Sedation: Is the use of IV chemical restraint WITHOUT ANESTHESIA. This sedation is typically in the form of a tranquilizer, a analgesic (opiate), and a muscle relaxant (benzodiazepine). That combination of medication is a safer alternative to anesthesia, and is reversible. This means that the patient wakes up smoothly, and is typically 100% recovered within 24 hours.
Anesthesia: is when patients are under general gas anesthesia, and are monitored using anesthetic monitor equipment during the procedure. There is a higher risk of life threatening complication in these cases. Recovery time is generally longer than with sedation.
