Special considerations

Ketamine should not be used alone in procedures of the pharynx, larynx (due to enact Gag reflex)
Mechanical stimulation of the pharynx should be avoided, whenever possible, if ketamine is used alone. Muscle relaxants, with proper attention to respiration, may be required in both of these instances
Respiratory depression may occur with over dosage or too rapid a rate of administration
Bronchodilation makes ketamine a favored induction agent for RSI during status asthmatics
