Abstract: Objective： To understand the use of antimicrobial agents in pediatric inpatients in hospital in 2019， so as to provide reference for promoting rational drug use in children. Methods： Data on antimicrobial use of pediatric inpatients in hospital in 2019 were investigated retrospectively.Results： Hospital in 2019， a total of 1 720 cases accepted antibiotic medication. Antimicrobial usage and intensity of use were 77.67% and 31.92 respectively. Disease status： congenital pneumonia was the most common (50.5%) in the NICU region， with mycoplasma pneumoniae (mycoplasma infection) ranking first or second in the general region. Intravenous antibiotic administration was the main route (97%). In the NICU region， the highest frequency of use was piperacillin sodium sulbactam sodium for injection and cefmenoxime for injection. The combined use rate of antibiotics in NICU region was 7.01% and that in puer region was 36.92%. With CDUI rationality evaluation of children dosage hint at different ages are antibacterial drug dosage unreasonable problems.Conclusion： The utilization rate and intensity of antibacterial drugs in pe-diatric inpatients were higher， and the proportion of intravenous drugs was higher. The use of antimicrobial agents is basically reasonable， but it is recommen-ded to clarify the indications for the use of antimicrobial agents as far as pos-sible in the case of empirical treatment and combined use. By calculating the C-DUI of antimicrobial drug use， it can be found that the use of some drugs is not reasonable， and the supervision， management and guidance on the use still need to be strengthened.
