BACKGROUND Bronchospasm in association with anaesthesia may appear as an entity in its own right or be a component of another problem such as anaphylaxis. It may present with expiratory wheeze, prolonged exhalation or, in severe cases, complete silence on auscultation. OBJECTIVES To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a specifi...

In the present study, the effect of aqueous extract of Momordica dioica, aqueous extract of Myrica esculenta and ethanolic extract of Euphorbia hirta a lone and in combinat ion on h istamine induced bronchospasm in guinea p ig, milk induced leukocytosis and eosinophilia in mice and on antipruritic activity in mice was done. In the animal model o f h istamine induced bronchospasm , all plant sho...

BACKGROUND: A helium-oxygen gas mixture (heliox) has low gas density and low turbulence and resistance through narrowed airways. The effects of heliox on pulmonary mechanics following severe methacholine-induced bronchospasm were investigated and compared to those of a nitrogen-oxygen gas mixture (nitrox) in an innovative pediatric porcine, independent lung, mechanical ventilation model. RESULT...

BACKGROUND Decreasing electrostatic charge on valved holding chambers increases the amount of drug delivered. However, there are no data demonstrating that this increases bronchodilatation. OBJECTIVE To investigate the influence of reducing electrostatic charge on the bronchodilator response to albuterol inhaler during nocturnal bronchospasm. METHODS This randomized double-blind, double-du...

Background The concentration of circulating catecholamine increases during exercise in healthy athletes, but the variation has not been studied much in athletes who develop exercise-induced bronchospasm. This study measured changes in circulating catecholamine levels using the induced maximal effort test in the laboratory in professional cyclists sensitive to bronchospasm. Materials and Metho...

Exercise-induced bronchospasm (EIB) is acute and reversible airway narrowing that occurs during, and also frequently after, exercise. Because the presenting symptoms of EIB are nonspecific, objective evidence of bronchospasm should be documented to confirm a diagnosis. A 10% or greater decrease in the forced expiratory volume in 1 second (FEV1) from baseline after an adequate exercise challenge...
