Abstract
Purpose: To investigate the therapeutic benefits of terbutaline sulfate aerosol inhalation combined with budesonide, and its influence on pulmonary function in pregnant women suffering from acute bronchial asthma attacks.
 Methods: A total of 100 pregnant patients diagnosed with acute bronchial asthma in PLA Strategic Support Force Characteristic Medical Center, Beijing, China were divided into control and study groups (n = 50 each). Control group received aerosol inhalation of normal saline along with standard treatments, viz, oxygen inhalation, sputum aspiration, anti-infection measures, and maintenance of water- electrolyte balance. Study group received combined terbutaline sulfate and budesonide aerosol inhalation in addition to standard treatment. Both groups underwent a 7-day treatment course, with inhalation therapy twice daily.
 Results: Study group showed significantly shorter relief times for cough, wheezing, and chest tightness compared to control group (p < 0.05). After treatment, 92.0 % of patients in study group exhibited improvement or relief from their symptoms, compared to 80.0 % in control group (p < 0.05). Pulmonary function indices, including first vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), and FEV1/FVC, improved in both groups after treatment. Study group exhibited significantly lower laboratory indices, including immunoglobulin E (IgE), C-reactive protein (CRP), and eosinophils (EOS) compared to control group (p < 0.05).
 Conclusion: The combination of inhalation therapy of terbutaline sulfate with budesonide in pregnant women experiencing acute bronchial asthma demonstrates significant enhancements in clinical effectiveness, pulmonary function, and laboratory parameters. Clinical trials of this combined therapy should be carried out in other locations to ascertain the effect of population variation on treatment efficacy.
