支气管扩张剂与低钾血症

BRONCHODILATOR AND HYPOKALEMIA

对支气管哮喘与喘息型慢性支气管炎住院患者36例,合用β_2受体激动剂与茶碱类制剂治疗,对比观察了用药前后补钾组与未补钾组血清钾浓度的变化,发现两组病人治疗后血清钾浓度均较治疗前有一定程度的降低,未补钾组降低程度显著,前后比较有非常显著性差异(P<0.01);但补钾组前后比较无显著性差异(P>0.05)。

36 Patients with bronchial asthma and chronic asthmatic bronchitis were treated with β_2-receptor agonists and theophyUine drugs. The Change of plasma potassium level were observed in K^+—treated group and not treated group before and after the treatment. It was found that after the treatment the plasma potassium level were reduced to certain degree in both groups. The Reduction was more obvious in the group without potassium supplied in which the difference before and after treatment was very Significant (P<0.01). But in the potassium supplied group the difference was not Significant (P>0.05). It was suggested that potassium chloride should beused as bronchodilator.
