Significant hyperkalemia may result from the intravenous administration of succinylcholine chloride to patients suffering from spinal cord injury, massive trauma, burns, central nervous system lesions, tetanus, or uremia. A case of cardiac arrest secondary to this phenomenon is reported. Succinylcholine should be used cautiously, if at all, in these patients from the time of injury until their "vulnerable period" has passed.
