This study describes the clinical, paraclinical characteristics and pathogens of pneumonia in 195 children with pneumonia at the Pediatric Department, Bach Mai Hospital from January to June 2019. According to the study results, most of the cases were aged under five (93.3%) with pneumonia clinical features of tachypnea, 99%; cough, 97.4%; crackling sound, 81.6%; respiratory failure, 80.5%; leukocytosis, 55.9%; and high CRP level in serum, 54.9%. There were 90 cases positive with incubated bacteria with the prevalence of three nasopharyngeal carriages: S.pneumoniae was 48.7%; H.influenzae, 27.8%; and M.catarrhalis, 18.3%. All the bacteria were susceptible to almost all the antibiotics used in treatment, such as Amoxicillin/acid clavunamic, cefotaxim and ceftriason. The study concludes that clinical and paraclinical characteristics in children with pneumonia were fairly various and bacterial pathogens of pediatric pneumonia were similar and susceptible to basic antibiotics.
