Input: Six trials involving 321 infants in three different settings were included. Compared with beta2-agonist alone, the combination of ipratropium bromide and beta2-agonist was associated with a reduced need for additional treatment, but no difference was seen in treatment response, respiratory rate or oxygen saturation improvement in the emergency department. There was no significant difference in length of hospital stay between ipratropium bromide and placebo; or between ipratropium bromide and beta2-agonist combined compared with beta2-agonist alone. However, combined ipratropium bromide and beta2-agonist compared to placebo showed significantly improved clinical scores at 24 hours. Parents preferred ipratropium bromide over nebulised water or placebo for relief of their children's symptoms at home. A further updated search conducted in June 2005 did not yield any new studies. There is not enough evidence to support the uncritical use of anti-cholinergic therapy for wheezing infants, although parents using it at home were able to identify benefits.
Output:

Six trials involving 321 infants in three different settings were reviewed. The review was unable to identify clear benefits in outcomes such as duration of hospitalisation or improvement in oxygenation though there were suggestions that some patients may benefit particularly in recurrently wheezy infants treated at home. Well designed studies are required to clarify the role of these agents in young children with wheeze.
