Objective: To investigate the clinical treatment methods and effects of patients with pregnancy-induced acute bronchial asthma. Methods: The duration of this study was 3 years, starting from January 2017 and ending in December 2019. The study subjects selected 56 outpatients with pregnancy-associated bronchial asthma from our outpatient clinic. The symptoms, clinical treatment methods and treatment effects and pregnancy outcomes were retrospectively analyzed. Results: Pregnant women with mild to moderate bronchial asthma had significant effects through oxygen inhalation, injection of glucocorticoids, β2 receptor agonist, fluid replacement and other related treatments. All of them were delivered normally around 40 weeks of pregnancy, without serious complications. Severe bronchial asthma pregnant women receive intravenous theophylline and glucocorticoid drugs on the basis of treatment of mild to moderate patients. One pregnant woman terminated her pregnancy at 33 weeks, two pregnant women developed respiratory acidosis, and one had restricted fetal growth. Conclusion: Patients with pregnancy-associated bronchial asthma should be treated in time for acute exacerbations to reduce the harm to pregnant women and fetuses. The use of aminophylline and glucocorticoids has obvious effects and can be widely used.
