Airway Reactivity to Bronchoconstrictor and Bronchodilator: Assessment Using Thin-Section and Volumetric Three-Dimensional CT
OBJECTIVE To determine the extent to which thin-section and volumetric threedimensional CT can depict airway reactivity to bronchostimulator, and to assess the effect of different airway sizes on the degree of reactivity. MATERIALS AND METHODS In eight dogs, thin-section CT scans were obtained before and after the administration of methacholine and ventolin. Cross-sectional areas of bronchi a...
متن کاملLack of correlation between bronchoconstrictor response and bronchodilator response in a population-based study.
Bronchodilator and bronchoconstrictor responsiveness have been considered physiological opposites in patients with obstructive airways disease. Provocation challenges have been replaced by bronchodilator tests in the assessment of cases of severe airways obstruction. The aim of this study was to examine the relationship between bronchoconstrictor and bronchodilator responsiveness, and their sup...
متن کاملEffect of an inhaled antihistamine (clemastine) as a bronchodilator and as a maintenance treatment in asthma.
Although intravenous chlorpheniramine can cause bronchodilatation, oral and parenteral antihistamines have not proved useful in treating asthma. Inhaled antihistamines may cause throat irritation, but a recent study of the antihistamine, clemastine, showed it to be an effective bronchodilator without irritant effects. We have extended these studies to determine the site of action of inhaled cle...
متن کاملEffects of two antihistamine drugs on actual driving performance.
A double blind placebo controlled experiment was conducted measuring the effects of the centrally active antihistamine triprolidine and the peripherally acting antihistamine terfenadine on actual driving performance in a group of experienced women drivers. Triprolidine greatly impaired driving behaviour, whereas terfenadine did not. Triprolidine also impaired subjective and objective measures o...
متن کاملAt what age do bronchodilator drugs work?
Using a modification of the forced oscillation technique we have measured respiratory resistance before and after nebulised salbutamol therapy in 32 wheezing children aged 7 months to 3 years 7 monts. 12 of the children were also studied in a total body plethysmograph. No child under 18 months of aged showed a greater than 5% fall in resistance or any fall in thoracic gas volume. In contrast, 1...
