Three Severe Acute Asthmatics Improved by β₂-agonist Inhalations via a Metered Dose Inhaler

Abstract

We presented three severe asthmatics who were improved dramatically by frequent inhalations of aerosolized β₂-agonist, using a metered dose inhaler.
Aerosolized β₂-agonist was inhaled repeatedly till patients were free from attack and/or wheezing. One was improved without an artificial ventilation and the other two were on the ventilator because of acute respiratory distress. Durations of an artificial ventilation (13hrs and 36hrs) were markedly shorter than that of previous report.
Frequent inhalations of β₂-agonist improved severe asthma attack rapidly without any severe cardiac and metabolic adverse effects.
