Effect of Bronchoalveolar Lavage on the Inflammatory Mediators and Pulmonary Function of Patients with Refractory Pneumonia / 现代生物医学进展

ABSTRACT

Objective:To study the effect of bronchoscope lavage on the inflammatory mediators and pulmonary function of patients with refractory pneumonia.Methods:100 cases of patients with refractory pneumonia who were treated in our hospital from January 2010 to December 2015 were selected and randomly divided into two groups,the control group was treated with routine clinical treatment,and the observation group was treated with bronchoscope lavage.The curative effect and the changes of inflammatory mediators and pulmonary function of the two groups after treatment were compared.Results:After treatment,the effective rate of observation group was 90.00％(45/50),which was significantly higher than that of the control group (76.00％,38/50) (P＜0.05);the levels of endotoxin,IL-6,TNF-2 and LPO in the bronchoalveolar lavage fluid of both groups were significantly decreased (P＜0.05),which were decreased more significantly in the observation group (P＜0.05),the pulmonary function of both groups were significantly improved(P＜0.05),which improved more significantly in the observation group(P＜0.05).Conclusions:Bronchoscope lavage had good therapeutic effect on the patients with refractory pneumonia,it could effectively reduce the level of inflammatory mediators and improve the lung function.
