Insights
A clinical score effectively assesses asthma attack severity in children, correlating well with pulse oximetry and spirometry. This method is valuable, especially where advanced pulmonary function tests are unavailable.
Area of Science:
- Pediatric Pulmonology
- Emergency Medicine
- Clinical Assessment
Background:
- Asthma attacks require accurate severity assessment for appropriate management.
- Existing methods like spirometry may be inaccessible in certain settings.
Purpose of the Study:
- To evaluate the relationship between clinical score, pulse oximetry, and spirometry in pediatric asthma exacerbations.
- To establish the utility of a clinical score for assessing asthma severity.
Main Methods:
- A randomized, double-blind, observational study involving 110 children (2-15 years) with asthma attacks.
- Clinical scores (based on respiratory rate, wheezing, dyspnea, retractions) and oxygen saturation were recorded.
- Pulmonary function tests (spirometry) were performed on 54 children aged 5+.
Main Results:
- A significant positive correlation was observed between oxygen saturation and the clinical score.
- Spirometric test results also showed a significant correlation with the clinical score in children.
Conclusions:
- The clinical score serves as a reliable indicator of asthma attack severity in children.
- This scoring system is particularly useful in resource-limited settings lacking advanced laboratory facilities for pulmonary function testing.
Background:
The aim of this study is to demonstrate the importance of the relation between clinical score, pulse oximetry and spirometric tests in an asthma attack.
Methods:
In this randomized, double blind, observational study, 110 children (age 2-15 years) with an asthma attack who were admitted to emergency room were evaluated. Patient history, physical examination, clinical score and oxygen saturation were recorded in all patients; however pulmonary function tests were obtained only in 54 children who were over 5 years of age. The clinical score was derived from respiratory rate, wheezing, dyspnea and retractions.
Results:
Both oxygen saturation and spirometric tests were found to be significantly correlated with the clinical score in children.
Conclusion:
The clinical score could be used for assessing the severity of the asthma attack particularly in developing countries where laboratory facilities are not available or pulmonary function tests are not feasible.

Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
