摘要
Background: Hyperkalemia has been described as a rare and under recognized cause of acute quadriplegia.
Case Report: A 52-year-old man with end-stage renal disease presented with ascending quadriplegia and dyspnea for 2 days. He had life-threatening hyperkalemia (9.0 mEq/L). His electrocardiogram showed typical features of hyperkalemia. His symptoms improved in 30 minutes and completely resolved in 5 hours after emergent treatment of hyperkalemia. He admitted eating large amounts of high potassium foods and taking ibuprofen in uncertain quantities. We reviewed 62 articles and identified 73 patients with secondary hyperkalemic paralysis. Common presentations were diminished reflexes, quadriparesis/paralysis, respiratory involvement, and sensory loss. Almost half of all patients had potassium levels higher than 9 mEq/L. Complete recovery, achieved in 89% of patients, did not correlate either with the absolute potassium level or the degree to which it was corrected.
Conclusions: Hyperkalemia is a rare but treatable cause of acute flaccid paralysis that requires immediate treatment. Late diagnosis can delay appropriate treatment leading to cardiac arrhythmias and arrest.
