Abstract
Objective:To analyze the clinical distribution characteristics and drug resistance of Acinetobacter baumannii(AB)isolated from lower respiratory tract samples in a 3A hospital,and to provide theoretical support for clinical preven-tion and treatment of infection caused by AB.Methods:A retrospective analysis was made of 694 strains of AB in Yangjiang People's Hospital from January 2023 to December 2024,including 531 strains from lower respiratory tract speci-mens(including sputum specimens、alveolar lavage fluid、bronchial lavage fluid,etc.).Statistics and analysis of AB strains isolated from lower respiratory tract bacterial culture samples and their drug resistance.Results:A total of 694 strains of AB were isolated from different specimen types,among which 531 strains of AB were isolated from lower respiratory tract specimens,and the detection rate was 76.51%.There were 326 strains of carbapenem resistant Acinetobacter baumannii(CRAB)in lower respiratory tract specimens,accounting for 61.39%.The distribution of AB strain in lower respiratory tract samples was the most in male patients,accounting for 72.69%,which was significantly different from that in female patients(P<0.05).In terms of age distribution,AB strains were the most in the elderly group,accounting for 43.50%,followed by the elderly group,accounting for 31.64%;Compared with other age groups,the distribution proportion in ad-olescent group was statistically significant(P<0.05).Among the 12 commonly used antibiotics,the resistance rate of CRAB to various antibiotics is generally high,and the highest resistance rate is piperacillin/tazobactam,reaching 99.39%.Conclusion:Strict aseptic operation should be performed in clinic,hospital infection monitoring in key departments should be strengthened,antibiotics should be used rationally,AB drug resistance should be curbed,and infection rate should be reduced.关键词
