What the FDA labels say
From the Sevoflurane (Ultane) label · effective 2025-01-13
Risk of Respiratory Depression Sevoflurane may cause respiratory depression, which may be augmented by opioid premedication or other agents causing respiratory depression.
Consider having an anticholinergic and epinephrine available when administering sevoflurane for induction in this patient population.
Benzodiazepines and Opioids Benzodiazepines and opioids would be expected to decrease the MAC of sevoflurane in the same manner as with other inhalational anesthetics.
During maintenance of anesthesia, the required dose of nondepolarizing muscle relaxants is likely to be reduced compared to that during N 2 O/opioid anesthesia.
In most cases, bradycardia improved with decreasing the concentration of sevoflurane, manipulating the airway, or administering an anticholinergic or epinephrine.
