Characteristics of pathogen of hospital infection in children with refractory Mycoplasma pneumoniae pneumonia and related factors

??Objective??To explore the pathogen characteristics and risk factors of nosocomial infection in children with refractory pneumonia caused by Mycoplasma pneumoniae. Methods??A total of 160 children??nosocomial infection??45 cases?? as observation group??no nosocomial infection??115 cases?? as control group?? with refractory MPP who were admitted from January 2015 to January 2018 were selected for pathogen detection and pathogen species analysis. Analyze the differences of two groups to detect the risk factors of hospital infection by means of univariate and multivariate logistic analysis. Results??According to the analysis of the pathogens??32 of them were bacterial infections??71.1%????and Gram-negative bacteria were the main pathogens??including Haemophilus influenza??9 cases????Klebsiella pneumonia??7 cases????Escherichia coli ??5 cases?? and Legionella pneumophila??2 cases????13 of them were viral infections??28.9%????including influenza B virus??6 cases????respiratory syncytial virus??5 cases??and adenovirus??2 cases??. After univariate and multivariate logistic analysis??no differences were found in sex??age??congenital heart disease or anemia between observation group and control group??P??0.05??. However??the length of hospitalization??season of onset??invasive procedures??non-single ward??and the irrational use of antibiotics in the two groups had significant differences??P??0.05??. Conclusion??The main infection pathogen of children with refractory MMP in nosocomial infection is Gram-negative bacteria. The risk factors of nosocomial infection are the length of hospitalization?? season of onset??invasive procedures??non-single ward??and the irrational use of antibiotics.
