喘息持续状态是支气管哮喘(以下简称哮喘)严重发作的持续发展,经一般支气管解痉药物治疗无效,以致喘息持续24小时以上而不缓解的严重状态,故又称严重哮喘(Severe Asthma)或致死性哮喘(FatalAsthma)。如不及时治疗或因处理不当,常可导致死亡。目前认为,哮喘的发病机理主要有①生物介质的释放;②迷走神经兴奋性增强;③β肾上腺素受体功能低下。它们最后可能是通过共同的途径,使支气管平滑肌痉挛、粘膜充血水肿、分泌物增加而引起哮喘发作。最近还发现有的哮喘病例,体内有抗自身平
The state of wheezing is the continuous development of severe attack of bronchial asthma (hereinafter referred to as asthma), the general bronchial spasm drug treatment ineffective, resulting in wheezing continued for 24 hours without serious condition, it is also known as severe asthma (Severe Asthma) or lethal FatalAsthma. If not treated promptly or due to improper handling, can often lead to death. At present, the pathogenesis of asthma mainly ① release of biological media; ② vagus excitability increased; ③ β-adrenergic receptor dysfunction. Finally, they may be through a common approach, so that bronchial smooth muscle spasm, mucosal congestion and edema, increased secretions caused by asthma attacks. Recently also found some cases of asthma, the body has anti-self-level
