An inexpensive spacer for use with metered-dose bronchodilators in young asthmatic children

Area of Science:

• Pediatric Pulmonology
• Medical Device Innovation
• Emergency Medicine

Background:

• Metered-dose inhalers (MDIs) are crucial for asthma management.
• Spacers improve MDI medication delivery, especially in children.
• Access to commercial spacers can be limited or costly.

Purpose of the Study:

• To evaluate the efficacy of a modified 1-liter plastic bottle as a low-cost spacer for metered-dose bronchodilators.
• To assess the effectiveness of this DIY spacer in children experiencing acute asthma attacks.

Main Methods:

• A 1-liter plastic soft drink bottle was adapted as a spacer device.
• Twenty-two children (3.9-7.5 years) with acute asthma were enrolled.
• Participants received aerosolized salbutamol or placebo via the modified bottle in a randomized controlled trial.

Main Results:

• Children receiving salbutamol via the plastic bottle spacer showed significantly improved bronchodilation compared to placebo.
• No significant adverse effects were reported during the study.
• The modified bottle demonstrated effective delivery of bronchodilator medication.

Conclusions:

• A 1-liter plastic bottle can serve as a convenient, inexpensive, and effective spacer for metered-dose bronchodilators.
• This approach offers a practical solution for delivering asthma medication to children, particularly in resource-limited settings.
• The modified bottle is a promising tool for managing acute asthma in pediatric populations.
