Use of tracheal auscultation for the assessment of bronchial responsiveness in asthmatic children.
BACKGROUND It can be difficult to assess bronchial responsiveness in children because of their inability to perform spirometric tests reliably. In bronchial challenges lung sounds could be used to detect the required 20% fall in the forced expiratory volume in one second (FEV1). A study was undertaken to determine whether a change in lung sounds corresponded with a 20% fall in FEV1 after methac...
متن کاملBronchodilator responsiveness using spirometry in healthy and asthmatic preschool children.
OBJECTIVE To assess repeatability and reproducibility of spirometry measurements, and bronchodilator responsiveness (BDR), in healthy 3-6-year-old preschool children and those with asthma. DESIGN Spirometry was performed before and 20 minutes after administering either inhaled placebo (for repeatability) or 400 μg salbutamol (for BDR) on two separate occasions (reproducibility) 3-23 days apar...
متن کاملBronchial responsiveness to inhaled propranolol in asthmatic children and adults.
Inhaled propranolol (P) was administered to a population which included asthmatic children (30 subjects) and adults (43 subjects): 1) to investigate the determinants of induced bronchial response; 2) to examine the relationship with treatment requirements; 3) to determine the relationship with responsiveness to methacholine (M) and ultrasonically nebulized distilled water (UNDW) (50 subjects); ...
متن کاملBronchial Responsiveness in Patients with Restrictive Spirometry
BACKGROUND Improvement in PFT after bronchodilators is characteristic of obstructive airway diseases such as COPD. However, improvement in patients with restrictive pattern is occasionally seen. We aim to determine the clinical significance of a bronchodilator responsive restrictive defect. METHODS Patients with restrictive spirometry and a bronchodilator study were identified at the Universi...
