雾化吸入联合体位引流对急性支气管炎患者的应用效果OA

Objective To explore the application effect of aerosol inhalation combined with postural drainage in patients with acute bronchitis.Methods A total of 80 patients with acute bronchitis admitted to the Affiliated Zhongshan Hospital of Dalian University from May 2023 to April 2025 were selected as the research subjects and they were divided into the drainage group(n=40)and the nebulization group(n=40)according to the random number table method.The drainage group received conventional treatment combined with postural drainage,while the nebulization group received conventional treatment combined with nebulization inhalation and postural drainage.The clinical symptom improvement,degree of cough relief,lung function,and airway resistance indicators of the two groups were compared.Results The time for severe cough to disappear,the time for complete cough to cease,the time for difficulty in expectoration to subside,the time for lung rales to disappear,and the time for chest tightness/shortness of breath to resolve were shorter in the nebulization group than in the drainage group.The expectoration effect of the nebulization group was better than that of the drainage group,and the difference was statistically significant(P＜0.05).After treatment,the Leicester cough questionnaire(LCQ)score of patients in the nebulization group was higher than that of the drainage group,and the difference was statistically significant(P＜0.05).After treatment,the vital capacity(VC),total lung capacity(TLC),and maximum voluntary ventilation(MVV)of patients in the nebulization group were higher than those in the drainage group,and the differences were statistically significant(P＜0.05).After treatment,the airway viscous resistance(R20),total airway viscous resistance(R5),and total air-way impedance(Z5)of patients in the nebulization group were lower than those in the drainage group,and the differences were statistically significant(P＜0.05).Conclusion In the treatment of acute bronchitis,the combined use of aerosol inhala-tion and postural drainage has significant advantages over simple postural drainage combined with conventional drug therapy.It can more quickly relieve symptoms such as coughing,difficulty in expectoration,chest tightness and shortness of breath in patients,shorten the time for disappearance of pulmonary rales;at the same time,it can more effectively improve the quality of life of patients,optimize lung function and reduce airway resistance.
