【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。更多还原

【Abstract】 [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.更多还原
