Hyperkalemia succinylcholine-induced

Succinylcholine-induced hyperkalemia may lead to cardiac arrhythmia and arrest when plasma reaches 7 and 10 mM, respectively. The drug also may precipitate a fulminant attack of malignant hyperthermia in susceptible individuals (not to be confused with neuroleptic malignant hyperpyrexia, which involves dopamine and the CNS). Treatment in either case consists of cooling the body and administering oxygen and dantrolene sodium (discussed later).
