Can you give Suxamethonium IM?
Practically, the intramuscular route is accessible. One can administer suxamethonium into the deltoid muscle without leaving the airway. One must, of course, have sufficient drug prepared beforehand and this may mean more than the conventional 100 mg to give the recommended dose of 4 mg.kg−1.
How fast do you give succinylcholine?
Succinylcholine generally takes 45—60 seconds for onset of laryngeal paralysis. When rocuronium is dosed at the lower end of this range, it's onset of action is longer than the 45—60 seconds required for succinylcholine.
