Abstract：Objective To explore the effect of alveolar lavage combined with fiberoptic bronchoscopy for sputum aspiration in the treatment of severe pneumonia with respiratory failure.Methods A total of 108 patients of severe pneumonia with respiratory failure admitted to the Second Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from June 2019 to December 2023 were selected as the research subjects.All patients were divided into a research group of 58 cases and a control group of 50 cases based on different treatment plans.The research group received fiberoptic bronchoscopy combined with bronchoalveolar lavage treatment,while the control group received sterile suctioning treatment.Compare the efficacy,clinical related indicators,as well as pulmonary infection scores and inflammatory factor levels before and after treatment between two groups.Results The total clinical effective rate of the research group was 96.55%,which was significantly higher than the control group's 82.00%(P<0.05).After treatment,the clinical indicators related to cough relief time,lung rale relief time,fever relief time,mechanical ventilation time,and antibiotic use time in the research group were all significantly shorter than those in the control group(P<0.05).After treatment,the lung infection score and inflammatory factor levels in the research group were significantly lower than before treatment,and the above indicators in the research group were significantly better than those in the control group(P<0.05).Conclusion The combination of alveolar lavage and fiberoptic bronchoscopy for sputum aspiration in the treatment of severe pneumonia complicated with respiratory failure can effectively improve the level of inflammation and pulmonary infection,and has a more ideal clinical effect,which is worth promoting and using.
