Objective To investigate the effect and safety of early electric bronchoscope on patients with nonresponding pneumonia. Method Seventy non responding pneumonia patients were selected from our hospital , who received treatments from January 2015 to April 2016.According to the random table ,patients were randomly divided into the observation group(34 cases)and the control group(36 cases). According to the experience and sputum culture results,patients in the control group were given the conventional therapy,and patients in the observation group were given bronchoscope and transbronchil lung biopsy(TBLB). The effect of bronchoscopy,the treatment curative effect,duration of fever,the period of the elevated CRP dropped to baseline,the length of hospital stay and medical costs were compared between the two groups. Results The diagnostic rate of bronchoscopy and the positive rate of airway suction bacterial culture in the observation group were similar with those in the control group,with no significant differences. The positive rate of airway suction bacterial culture was significantly higher than that of sputum culture in the observation group. The positive rate of airway suction bacterial culture was higher than that of sputum culture in the control group ,but with no significant difference.The total effective rate in the observation group(87.1%)was significantly higher than that in the control group(58.8%). The duration of fever and the time of the elevated CRP dropped to baseline in the observation group were significantly shorter than those in the control group. The hospital stay and hospital costs in the observation group were also significantly lower than those in the control group. Conclusion Early bronchoscopy can obtain diagnosis evidence of etiology and histology and improve the diagnostic rate,meanwhile,it also has a therapeutic effect.It can improve the clinical treatment effect and shorten the healing time and the cost of hospitalization. In addition , early electronic bronchoscopy has fewer adverse reactions and it may play an important role in diagnosis and treatment on nonresponding pneumonia patients.

Objective　To investigate clinical features of neonatal ventilator associated pneumonia.Methods　Retrospective analysis of clinical features was performed in twenty-two newborns with ventilator associated pneumonia.Results　Ventilator associated pneumonia were found in 22 ou t of 36 neonates with mechanical ventilation.Conclusion　The incidence of VAP is significantly increased if the time of mechanical ventilation in longer than 96 hours.
