Chronic Asthma

It is likely that these complications may occur especially in the presence of hypoxia or acidosis, or in asthmatic patients with preexisting cardiovascular disease. Therefore, the measurement of the serum electrolyte levels before and during the management of asthma exacerbation with bronchodilators may reduce such risks if corrected.
Although this study has important clinical findings, it has several possible limitations. The first limitation is the absence of a control group. Secondly, the sample size was not large enough to permit extensive analysis on the effect of therapy on asthmatic patients with low sodium and potassium levels. Thirdly, the effect of the electrolyte abnormality on patients with chronic asthma was also overlooked; however, this was not among the objectives of the study.  there 
In conclusion, hypomagnesemia and hypophosphatemia were found to be the most common electrolyte abnormalities in patients with chronic, stable asthma. The underlying cause still remains unknown. The possibility of dietary or genetically determined factors may explain some of the other underlying causes. However, further studies are needed to confirm our findings and to clarify these speculations. In addition, to avoid any potential cardiac and respiratory hazards in patients with chronic asthma and exacerbation, we recommend the measurement of serum electrolyte levels before bronchodilator therapy is administered.
