Managing acute severe asthma, part 1: What therapies to try, and when
February 1st 2007The initial assessment of acute severe asthma includes confirmation of the diagnosis and rapid assessment of mental status and degree of respiratory distress. The severity of airflow obstruction is best determined by forced expiratory volume in 1 second or peak expiratory flow rate. While inhaled ß2-agonists are the initial therapy, the combination of ipratropium and a ß2-agonist can enhance results in some patients. There also is evidence that inhaled corticosteroids can lead to a more rapid improvement in pulmonary function. (J Respir Dis. 2007;28(2):57-64)
