使用气零决给溴化异丙阿托品能引起哮喘患者发生异常的支气管收缩,其作用机理未明,但可能是对溴化物的特异性反应。溶液的渗透性对引起支气管收缩有一定作用,常用的澳化异丙阿托品是低渗性溶液,吸入低渗性溶液可能产生支气管收缩,本文研究溶液渗透性与异常的气道反应的关系。 The use of gas zero to give propranolol bromide can cause abnormal bronchoconstriction in patients with asthma, the mechanism of which is unknown, but may be a specific response to bromide. Permeability of the solution on the bronchial contraction caused by a certain role, commonly used isopropylallyl Australia is a hypotonic solution, inhaled hypotonic solution may produce bronchoconstriction, the study of solution permeability and abnormal airway response.
