婴幼儿急性支气管痉挛首选药物为选择性β_2拮抗剂。最近研究指出大剂量多次应用舒喘灵(Albuterol)包括持续气雾吸入在缓解急性气道梗阻更为有效,然而持续气雾吸入治疗的安全性,尤以对心脏潜在毒性尚未详细观察,本文报道持续气雾吸入治疗急性严重支气管痉挛的全部患儿常规监测肌酸磷酸激酶(CK)、肌酸磷酸激酶-心脏同功酶(CK-MB)和心电图(EKG) The preferred drug for acute bronchospasm in infants and young children is selective β_2 antagonist. Recent studies indicate that high-dose repeated use of Albuterol, including continuous aerosol inhalation, is more effective in relieving acute airway obstruction. However, the safety of sustained aerosol inhalation therapy, especially for the potential toxicity of the heart, has not been observed in detail It was reported that all patients with persistent severe aerosol inhalation of acute severe bronchospasm were routinely monitored for creatine phosphokinase (CK), creatine phosphokinase-cardiac isoenzyme (CK-MB), and electrocardiogram (EKG)
