Dosing Considerations1

ULTANE exposure should not exceed 2 MAC-hours at flow rates of 1 to <2 L/min. Fresh gas flow rates <1 L/min are not recommended.

The concentration of ULTANE required for maintenance of general anesthesia is age dependent.
In pediatric patients, the MAC equivalent dose of ULTANE should be reduced when used with nitrous oxide.
