Hyperkalemic cardiac arrest following succinylcholine administration: The use of extracorporeal membrane oxygenation in an emergency situation.

We report an 11-year-old male with undiagnosed myopathy, who developed cardiac arrest secondary to severe rhabdomyolysis and hyperkalemia following succinylcholine administration. The patient required extracorporeal membrane oxygenation support from which he was eventually weaned successfully. He died eleven days after the cardiac arrest as a result of apparent ischemic brain injury.
