Objective: To explore the effects of bronchoscopy alveolar lavage in the treatment of severe pneumonia caused by multiple drug bacterial infection. Methods: A total of 84 patients with severe pneumonia infected by multi-drug resistant bacteria were randomly selected from Kunming Second People’s Hospital, which is our hospital from January 2019 to December 2020 for this research. They were divided into a reference group and a study group using a digital table method, with 42 cases in each group. The reference group was given the routine treatment, the research group performed bronchoscopy alveolar lavage on this basis to observe the curative effect. Results: Before treatment, there was no significant difference in serum factor indexes and blood gas analysis indexes between the two groups of patients, P>0.05. After treatment, the time of fever, cough, moist rales disappearing and infection control time in the study group were shorter than those in the reference group, P<0.05. Serum tumor necrosis factor ? (TNF-??), interleukin-6 (IL-6) and interleukin-8 (IL-8) levels were lower than the reference group, and the arterial partial pressure of oxygen (PO2) and oxygen saturation (SO2) were both lower than the reference group, P<0.05. The effective rate of the treatment in the study group was higher than that in the reference group, P<0.05. Conclusion: Bronchoscopic alveolar lavage treatment can effectively improve the clinical symptoms of patients with severe pneumonia caused by multi-drug resistant bacterial infection, and the effects are significant.
