Abstract: Objective:To investigate the application of antibacterial medicines in pediatric respiratory diseases to search for effective ways of management and intervention.Methods:The medical records of 298 children with respiratory diseases treated in Suqian TCM Hospital from December 2017 to January 2019 were collected and analyzed.Results:Among the 298 cases, the utilization rate of antibiotics in children with acute upper respiratory tract infection was 63.2%, and that in children with tracheal bronchitis reached 83.9%,the difference being statistically significant(P<0.01).Among the 298 cases, the total utilization rate of antibacterial drugs was 85.2%, that of oral antibacterial drugs was 62.2%, and that of injection antibacterial drugs was 50.8%.The common antibiotics prescribed were cephalosporins (63.4%), penicillins (41.3%), macrolides (31.8%), and others (7.0%), etc. About 61.4% of patients were treated with one antibacterial drug alone, 30.8% with two combined drugs, 7.4% with three combined drugs and 0.3% with four combined drugs, respectively, and the difference was statistically significant (P<0.01).Conclusion:The use of antimicrobial agents in children's respiratory diseases in this region is not very reasonable, which is manifested in the deficiency in drug indication, route of administration, variety selection and combination of drugs. It is still very important to raise awareness of antimicrobial resistance, organize education and training, and strengthen the construction and supervision of primary health care.
