- Abstract: Objective To summarize changes in antibiotic resistance of Salmonella typhimurium enteritis in children in our hospital and analyze its treatment.Methods A total of 186 children with Salmonella typhimurium enteritis in the pediatrics department of our hospital were selected.The drug resistance of common antibiotics against Salmonella typhimurium for children was analyzed,and the annual and pre-/post-treatment changes of multi-drug resistant bacteria were also analyzed.Based on the initial treatment of antibiotics and the first drug sensitivity test results,patients were divided into the initial sensitive group(121 cases)and the initial insensitive group(65 cases).The hospital stay and fecal culture negative conversion time were compared between the two groups of children.Results Among the Salmonella typhimurium isolated from 186 children,the resistance rate of Salmonella typhimurium to commonly used cephalosporin antibiotics in pediatrics demonstrated an overall upward tendency.Among them,the resistance rates of ceftriaxone(43.6%)and cefotaxime(35.5%)were relatively high.From 2017 to 2019,the proportion of multi-drug resistant bacteria presented a gradual upward trend,while from 2020 to 2023,the proportion declined.The incidence of multi-drug resistant bacteria exhibited an increasing trend after treatment(P＜0.05).After 1 week of treatment,there were no significant differences in the above three types of drug resistance changes.The hospital stay and the time for fecal culture to turn negative were both shorter in the initial sensitive group than those in the initial insensitive group(P＜0.05).Conclusion The problem of bacterial resistance in Salmonella typhimurium enteritis in children is severe.Initial empirical treatment with sensitive antibiotics and a reasonable course of anti-infective treatment can help reduce the bacterial drug resistance rate and shorten the hospital stay.
