For endotracheal intubation, do not reduce the dose of nondepolarizing muscle relaxants or succinylcholine.
During maintenance of anesthesia, the dose of nondepolarizing muscle relaxants is likely to be reduced compared to that during N2O/opioid anesthesia.
Administration of supplemental doses of muscle relaxants should be guided by the response to nerve stimulation.
DRUG INTERACTIONS No clinically significant adverse interactions with commonly used preanesthetic drugs, or drugs used during anesthesia (muscle relaxants, intravenous agents, and local anesthetic agents) were reported in clinical trials.
