[Emergency diagnosis and treatment of bronchial asthma].

Abstract

Bronchial asthma is a kind of heterogeneous respiratory disease, and its emergency diagnosis and treatment face multiple challenges. This article, based on the evolution of domestic and international guidelines and consensus, explores the current confusions and shortcomings in the emergency treatment of asthma, considering the clinical specifics of emergency medicine. Due to the limited applicability of classifications such as "refractory asthma" and "severe asthma" in emergency settings, as well as the complex diagnostic process that makes clinical operations difficult, it is proposed to unify the diagnostic terminology as "acute exacerbation of bronchial asthma" (mild, moderate, severe, critical severe) in emergency work. Assessment indicators, such as arterial oxygen partial pressure (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), arterial oxygen saturation (SaO₂), peak expiratory flow (PEF). Simplified were simplified. The clinical diagnosis and emergency management should prioritize the approach outlined in the Chinese guidelines for the prevention and treatment of bronchial asthma (basic version). For mild-to-moderate and severe exacerbations, a tiered treatment strategy is recommended, focusing on rapid symptom relief, standardized glucocorticoid use, and dynamic efficacy assessment. Additionally, the urgent need for formulating a Chinese expert consensus on emergency diagnosis and treatment of bronchial asthma is highlighted, along with promoting multicenter prospective studies to optimize emergency protocols and improve patient prognosis.
