Meta Analysis
The use of ipratropium bromide for the management of acute asthma exacerbation in adults and children: a systematic review.
Ipratropium bromide is a quaternary anticholinergic bronchodilator that is commonly used to treat obstructive lung disease. Although ipratropium is not usually employed as a first-line bronchodilator to treat chronic asthma, it has been used extensively in hospital emergency departments as adjunctive therapy for the emergency treatment of acute asthma exacerbation. This review will summarize the physiological actions of ipratropium and the rationale for its use as an anticholinergic bronchodilator. ⋯ In conclusion, there is a modest statistical improvement in airflow obstruction when ipratropium is used as an adjunctive to beta2-agonists for the treatment of acute asthma exacerbation. In pediatric asthma exacerbation, use of ipratropium also appears to improve clinical outcomes; however, this has not been definitively established in adults. It would seem reasonable to recommend the use of combination ipratropium/beta2-agonist therapy in acute asthmatic exacerbation, since the addition of ipratropium seems to provide physiological evidence of benefit without risk of adverse effects.

Exhaled nitric oxide levels are elevated in asthmatic children and decrease after inhaled steroid treatment. We evaluated the time-dependent changes in fractional exhaled nitric oxide concentration (FENO) and pulmonary function parameters following inhaled steroid therapy. Thirty-nine steroid-naive atopic patients (age 11.92+/-0.48 years) with mild intermittent asthma and 22 age-matched healthy controls were enrolled in the study; pulmonary functions and FE(NO) levels were measured. ⋯ Sixteen of the 39 asthmatic patients were evaluated on two occasions after the beginning of treatment, at days 10 and 40. The significant reduction in FE(NO) levels (p < 0.01) and the significant increase in FEV1 and FEF(25-75%) values observed (p < 0.05) after 10 days did not further improve at day 40. These data show that it is possible to demonstrate early effects of low-dose inhaled steroids in asthmatic children using objective measurements of airway caliber and inflammation.
