ABSTRACT
Objective To provide reference for anti-infection drugs in Zunyi area by analyzing the etiological characteristics of children with severe pneumonia.Methods The sputum, throat swabs and serum of children with severe pneumonia in pediatric intensive care unit of our hospital from January 2014 to December 2015 were collected in this study.The pathogen species which caused severe pneumonia were detected and identified by the method of pathogen culture,and typical pathogens were detected by RT-PCR and indirect immunofluorescence.Results A total of 337 children with severe pneumonia were included,the pathogen positive rate was 86.65%(292/337).The rate of viral infection(37.32%)was the highest,followed by bacterial infection accounting for 28.42%,then the mixed infection accounting for 27.74%,and the mycoplasma pneumoniae infection accounting for 6.50%.The respiratory syncytial virus type B accounting for 28.44% was the most common in viral infection,and there were significant differences in age distribution(P<0.05),the children under 3-years-old,especially the infants under 1-year-old had the highest susceptibility.Viral infection had certain seasonality,compared with spring and winter,autumn and winter(November to April) had higher viral detection rate and the difference was statistically significant(x2=29.28,P=0.001).The escherichia coli was the most common in bacterial infection,accounting for 21.69%.Klebsiella pneumoniae,Escherichia coli were more common in neonates and infants under 1-year-old,Haemophilus influenzae occured in 1~3 years old children,Streptococcus pneumoniae infection could occur in any age.Conclusion Viral infection is the most common pathogen in children with severe pneumonia in Zunyi area followed by bacterial infection,which is more common in children under 1-year-old,and with the high incidence in autumn and winter.Bacterial infection is more common in children over 3 years of age.Bacterial and viral mixed infection is common in children under 3 years of age,especially in children under 1-year-old.
