[Abstract] Objective: To investigate the effect of fiberoptic bronchoscopy lung wash blood gas analysis and efficacy in patients with severe pulmonary infection. Methods: According to random number table in our hospital, our hospital in 2017 from 6 to June 2019 were treated 60 cases of severe pulmonary infection were divided into observation group and control group, 30 cases in each group. Administered to the control group NPPV treatment, observation group with a bronchoscope bronchial wash treatment based on the untreated controls. Observation arterial oxygen (PaO2) two groups of patients, arterial carbon dioxide tension (PaCO2), arterial oxygen saturation changes (SaO2) level, the total efficiency of the treatment the two groups. RESULTS: There were PaO2, SaO2 levels than those before treatment significantly increased, and the observation group was significantly higher (P <0.05), groups were significantly decreased PaCO2, observation group was significantly lower than the control group (P < 0.05); the total effective rate was observed (96.67%) was significantly higher (73.33%), P <0.05. Conclusion: The bronchoscope bronchial lavage applied to the treatment of severe pulmonary infection, can significantly improve the level of blood gas analysis indicators patients, improve clinical outcomes.
