Errors in inhalation technique and efficiency in inhaler use in asthmatic children
Allergy
|February 1, 1986
Summary
Many asthmatic children struggle with inhaler use, with less than half demonstrating effective technique. Proper instruction and technique checks are crucial for efficient asthma management in children.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Clinical Pharmacy
Background:
- Inhaler therapy is a cornerstone of asthma management in children.
- Suboptimal inhaler technique can lead to poor disease control and increased healthcare utilization.
Purpose of the Study:
- To assess the inhalation technique efficiency in asthmatic children.
- To identify factors influencing correct inhaler use and common errors.
Main Methods:
- 256 asthmatic children receiving regular inhalation therapy were studied.
- Pulmonary function measurements (PFM) and technique error recording were performed before and after inhaler demonstrations.
- Efficiency was defined as a >=15% increase in FEV1 post-inhalation.
Main Results:
- Only 45% of children demonstrated an efficient inhalation technique.
- Technique efficiency varied by device (pressurized aerosol 46%, tube spacer aerosol 59%, rotahaler 46%) and instructor group (17%-84%).
- Coordination issues, rapid/nasal inhalations were common errors; children under 6 years had more errors.
Conclusions:
- A significant proportion of asthmatic children use inhalers inefficiently.
- Clear, supervised instructions and regular technique assessment are vital for effective asthma treatment.
- Device choice and instructor quality impact technique efficiency.
