- Scientific TitleThe protective effect of a single dose salbutamol against exercise induced inspiratory airflow obstruction in asthmatic children
- ACRONYMN/A
- hypothesisProfylactisch 200ugr salbutamol kan tot 50% beschermen tegen de inspiratoire luchtwegobstructie gemeten in MIF50 die bij de meerderheid van de astmatische kinderen met FEV1 daling tijdens/na inspanning optreedt.
- Healt Condition(s) or Problem(s) studiedExercise induced Asthma, Inspiratory airflow obstruction
- Inclusion criteria- Clinical history of EIB.
- Age 8 till 16 years old.
- Ability to jump or run and perform reproducible lung function tests, i.e. coefficient of the predicted value variation in 3 of 5 consecutive measurements < 5%.
- Exclusion criteria- Exacerbation in the last 4 weeks prior to the ECT (hospital admission or use of systemic corticosteroids).

- Brief summaryExercise induced bronchoconstriction (EIB) is a highly frequent and specific symptom of asthma and also the most bothersome as reported by asthmatic children. Exercise challenge tests (ECT) can identify EIB and are therefore frequently used to diagnose and evaluate asthma. Salbutamol provides excellent protection against EIB, however in daily life prophylactic salbutamol does not always prevent exercise induced symptoms in asthmatic children. A recent study demonstrated that the majority of children with EIB have besides expiratory also inspiratory airflow obstruction. This means that exercise can induce narrowing of the larger airways, possibly as a response to EIB. It is not known to what extent salbutamol can reduce this inspiratory airflow obstruction. Main objective of this study is to investigate if salbutamol protects against inspiratory airflow obstruction.
