惊恐障碍误诊为低钾性周期性瘫痪的临床分析

目的探讨惊恐障碍和低钾性周期性瘫痪患者的临床鉴别诊断方法以减少误诊。方法选择2008年1月至2011年1月该院急诊科以低钾性周期性瘫痪收治的惊恐障碍患者7例(惊恐障碍组),同期本院收治的低钾性周期性瘫痪患者192例(低钾周期性瘫痪组),比较两组患者临床资料。结果惊恐障碍组患者平均肌力(3.7±0.81)级]、平均血钾(3.1±0.56)mmol/L]与低钾性周期性瘫痪组平均肌力、平均血钾分别为(2.4±0.84)级、(2.3±0.83)mmol/L]比较,差异有统计学意义(P<0.05)。结论对临床急性发病的肢体无力伴有明显焦虑情绪者,应当考虑到惊恐障碍的可能性以减少误诊。

Clinical analysis on 7 cases of panic disorder misdiagnosed as hypokalemic periodic paralysis

Objective To analyze the clinical differential diagnostic method of panic disorder and hypokalemic periodic paralysis for reducing misdiagnosis.Methods 7 cases of panic disorder(panic disorder group) misdiagnosed as hypokalemic periodic paralysis in the emergency department from January 2008 to January 2011 and contemporaneous 192 cases of hypokalemic periodic paralysis(hypokalemic periodic paralysis group) as control were selected.The partial clinical data were compared between the two groups.Results The average muscle strength was(3.7±0.81) grades in the panic disorder group and(2.4±0.84) grades in the hypokalemic periodic paralysis group;the average serum potassium level was(3.1±0.56)mmol/L in the panic disorder group and(2.3±0.83)mmol/L in the hypokalemic periodic paralysis group,showing statistical difference between the two groups(P<0.05).Conclusion The patient with acute onset and limb asthenia complicating obvious anxiety mood should be considered the possibility of panic disorder for reducing misdiagnosis.
