摘　　要：目的探讨老年支气管哮喘急性发作时低钾血症的临床特点。方法对该院2001年1月～2004年6月因哮喘急性发作收住入院并发低钾血症老年病例进行回顾性分析。结果老年支气管哮喘急性发作46例,合并低钾血症者20例,发生率高达43.5%。其中,病情重、病程长并发率明显高于病情轻、病程短者(P<0.01)。多种原因导致低钾,其临床表现缺乏特异性,易漏诊。结论老年支气管哮喘急性发作合并低钾血症的发生率高,潜在危险性大,应及时有效补钾。[Objective] To investigate clinical features of hypokalemia in elderly patients with acute episode of bronchial asthma. [Methods] Clinical data of the elderly patients with acute episode of bronchial asthma were analyzed retrospectively. [Results] 20 elderly patients with the complication of hypokalemia were identified from 46 patients with acute episode of bronchial asthma, with the incidence of the complication of 43.5%. Among these patients, the incidence of the complication was higher in patients with moderate- severe asthma and long duration of asthma than those in mild asthma and short duration of asthma （P 〈0.01）. Multiple factors were involved in＇ the occurrence of hypokalemia during acute episode of bronchial asthma, due to unspecific clinical manifestation, hypokalemia was easy to escape detection. [Conclusions] Hypokalemia was highly likely in elderly patients with acute episode of bronchial asthma, which poses potential danger for the patient. Potassium supplement should be administered in time and effectively.
