Abstract Objective To investigate and analyze of the effect of antibiotic bronchoalveolar lavage on pulmonary function and inflammatory mediators in patients with severe bacterial pneumonia. Methods From January 2015 to November 2016, in Huaihua First People's Hospital, 60 patients with severe bacterial pneumonia were selected, according to the random number table method, they were divided into observation group and control group, with 30 cases in each group. The control group was treated with antibiotics by intravenous administration, and the observation group was treated with antibiotic by bronchoalveolar lavage on the basis of the control group. The lung function index of forced epiratory volume in one second (FEV1), peak expiratory flow rate (PEFR) and max volume value (MVV), the inflammatory factor of lipopolysaccharide (LPS), tumor necrosis factor-2 (TNF-2) and interleukin-6 (IL-6) before and after treatment in two groups were compared. Results Before the treatment, the FEV1, PEFR, MVV in two groups were compared, the differences were not statistically significant (P > 0.05), after the treatment, the FEV1, PEFR, MVV in two groups were significantly better than before the treatment, the differences were statistically significant (P < 0.05), and observation group were significantly better than the control group, the differences were statistically significant (P < 0.05). Before the treatment, the LPS, TNF-2 and IL-6 in two groups were compared, the differences were not statistically significant (P > 0.05), after the treatment, the LPS, TNF-2 and IL-6 in two groups were significantly better than before the treatment, the differences were statistically significant (P < 0.05), and observation group were significantly better than the control group, the differences were statistically significant (P < 0.05). Conclusion Application of antibiotic bronchoalveolar lavage in the treatment of elderly patients with severe bacterial pneumonia can effectively improve the patient's lung function, effectively control and alleviate the lung inflammation, the application of treatment have good clinical effect, and it′s worthy of further clinical application.
