What drugs are usually used in iv general anesthesia ?

GA drugs: General anesthesia=unconsciousness. Anesthetic agents commonly used with a ga are propofol, ketamine. Any anesthetic/sedative/opioid regardless of route of administration can be a general anesthetic (can cause unconsciousness). Hope it helps.

Several: A continuous infusion of an induction agent such as proposal along with an infusion of a narcotic. Standard meds are also given by iv.

Primarily propofol: There are several IV meds but none have the "complete" profile for propofol as it has many characteristics needed for general anesthesia: amnesia, hypnosis and pain reliever. Despite its notoriety in the past by an androgynous pop star, its very safe in the proper hands of a professional who knows enough to monitor his/her patients diligently.
