Metered-dose inhalers with spacer produced outcomes that were at least equivalent to nebuliser delivery. Spacers may have some advantages compared to nebulisers for children with acute asthma.
Comparison of beta-adrenergic agents delivered by nebulizer vs metered dose inhaler with InspirEase in hospitalized asthmatic patients.
The present study was undertaken to determine if beta-agonists delivered by nebulizer provide better clinical responses than MDI therapy in status asthmaticus. We divided 28 hospitalized asthmatic patients into three groups. Group 1 received albuterol by MDI with InspirEase. Group 2 received nebulized albuterol. Group 3 received nebulized metaproterenol. Both nebulizer regimens resulted in significant improvements in both FVC and FEV1 by 30 min after initial hospital beta-agonist treatment. No significant improvement was noted in initial spirometry in the MDI with InspirEase group. In spite of the superiority of nebulizer therapy in the initial phase of hospitalization, the daily rates of spirometric improvement and duration of hospitalization were not significantly different among the three groups. Our results indicate that nebulizer therapy provides superior spirometric improvement in the initial phase of status asthmaticus. However, both MDI and nebulizer regimens provided similar rates of spirometric improvement and duration of hospitalization.
