Objective To explore the effect of Yangxue oral liquid and conventional western medicine treatment on blood gas indexes in patients with chronic bronchitis. Methods The study started in June 2021 and ended in May 2022. The subjects included were all confirmed chronic bronchitis patients, a total of 200 cases, and the 200 patients were divided into control group (100 cases) and treatment group (100 cases) using the digital table method. Both groups received the same conventional western medicine treatment. The control group was treated with amoxicillin capsules, ambroxol hydrochloride, and aminophylline tablets; the treatment group was treated with Yangxue oral liquid. The efficacy, blood gas analysis indicators [blood oxygen saturation (SaO2), arterial carbon dioxide (PaCO2), arterial oxygen partial pressure (PaO2)], clinical symptom scores (cough, sputum, lung wheezing, dyspnea, anorexia, abdominal distension, loose stools, and weakness and heaviness in limbs), clinical symptom resolution time, and safety information were compared between the two groups. Results The total effective rate (98.00%) of the treatment group was better than that of the control group (89.00%); after treatment, SaO2 was higher than that of the control group, and PaCO2 was lower than that of the control group (P<0.05); the improvement of clinical symptom and sign scores in the treatment group was significantly better than that in the control group, and the time of clinical symptom resolution was also shorter than that in the control group (P<0.05); in terms of safety, the incidence of adverse reactions in the control group was 8.00% higher than that in the treatment group (0.00%), with significant differences (P<0.05). Conclusion Yangxue oral liquid has a definite effect on the treatment of chronic bronchitis with ambroxol hydrochloride, can improve the bodys immunity, improve blood gas analysis indicators, and is safe and reliable.
