Insights
Metered dose inhalers with accessory devices (MDI/AD) are as effective as small volume nebulizers (SVN) for treating acute asthma in children. This study found no significant difference in outcomes between the two delivery methods for beta2-agonist medication.
Area of Science:
- Pediatric Emergency Medicine
- Respiratory Medicine
- Pharmacology
Background:
- Acute asthma exacerbations are common in children.
- Nebulizers have traditionally been used for delivering beta2-agonists in acute asthma.
- Alternative delivery methods are being explored for efficacy and accessibility.
Purpose of the Study:
- To compare the effectiveness of beta2-agonist administration via Metered Dose Inhaler with Accessory Device (MDI/AD) versus Small Volume Nebulizer (SVN).
- To evaluate treatment outcomes in children with acute asthma exacerbation receiving beta2-agonist therapy.
Main Methods:
- A cross-sectional study involving 150 children (≥6 months) with acute asthma exacerbation in an Emergency Room.
- Children were randomized to receive salbutamol via MDI/AD (Group A) or SVN (Group B).
- Clinical variables and Peak Expiratory Flow Rate (PEFR) were assessed pre- and post-treatment.
Main Results:
- No significant differences were observed in demographic characteristics or outcome measures between the MDI/AD and SVN groups.
- PEFR showed significant improvement in both groups post-treatment.
- Comparative analysis of PEFR between groups did not yield statistically significant differences.
Conclusions:
- MDI/AD administration of beta2-agonists is an effective alternative to SVN for treating acute asthma exacerbations in pediatric emergency settings.
- This finding supports the use of MDI/AD for efficient and comparable asthma management in children.
Objective:
To determine whether the administration of beta2-agonist by Metered Dose inhaler (MDI) with accessory device (AD) is a as effective as the administration of beta2-agonist by small volume nebulizers (SVN) for the treatment of acute asthma.
Methods:
A cross sectional study was conducted at Emergency Room (ER) of National Institute of Child Health (NICH), Karachi, between October 2000 to March 2001. This study included 150 children, 6 months and older with a history of wheeze and presenting with an acute asthma exacerbation. Children were categorized into mild, moderate and severe asthma according to medical scoring system. Children were assigned randomly into group A and B to receive standard dose of beta2-agonist (salbutamol) by MDI/AD (group A) or SVN (group B). Baseline characteristics and asthma severity were recorded. All variables (dyspnoea, use of accessory muscles, cyanosis, respiratory rate, heart rate, blood pressure, oxygen saturation, pulsus paradoxus, and wheeze) and Peak Expiratory Flow Rate (PEFR) in children 5 years and older, were determined at pre and post inhalation therapy.
Results:
Both groups did not differ in demographic characteristics. There were no significant differences in outcome measures. In children treated with MDI/ADs and SVNs. PEFR increased significantly in both the groups after completion of treatment, but PEFR was not statistically significant when compared in between groups.
Conclusion:
The data suggested that MDI/AD is an effective alternative to nebulizer for the treatment of children with acute asthma exacerbation in the ER.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
