Abstract
Objective To understand the characteristics and drug resistance of pathogenic bacteria in thoracic and cardiac surgery in the First People's Hospital of Qinzhou 2020 to 2023,so as to reduce the risk of nosocomial infection.Methods A retrospective analysis was performed on 1242 patients admitted to Department of Cardiothoracic Surgery in the First People's Hospital of Qinzhou from January 2020 to December 2023.The etiological data were collected,and the risk of infection,infection site,pathogen distribution and susceptibility of commonly used antibiotics were analyzed.Results From 2020 to 2023,there were 1242 cases of Department of Cardiothoracic Surgery in the First People's Hospital of Qinzhou,among which 191 cases had postoperative nosocomial infection,the total incidence was 15.38%,and the nosocomial infection rate decreased year by year.Among 191 patients with postoperative infection after thoracic and cardiac surgery,respiratory system infection was the most common,accounting for 58.64%.Among 191 patients with postoperative infection,274 strains of pathogenic bacteria were isolated,including 122 strains of gram-negative bacteria(44.53%),mainly Acinetobacter baumannii(25.55%),140 strains of gram-positive bacteria(51.09%),12 strains of fungi and Candida albicans(4.38%).The resistance rate of Staphylococcus haemolyticus and Staphylococcus aureus to vancomycin was the lowest,both were 0.The resistance rate of Acinetobacter baumannii to cefoperazone/sulbactam was 48.57%.The resistance rate of Pseudomonas aeruginosa to piperacillin/tazobactam and cefoperazone/sulbactam was higher,while resistance rate to cefepime and meropenem are comparatively lower at 21.74%and 32.61%,respectively.Conclusion The incidence of nosocomial infection is high after thoracic and cardiac surgery,so clinical work should focus on strengthening the prevention and management of nosocomial infection.When patients present with symptoms of infection,pathogen culture and susceptibility testing are needed to make effective anti-infective treatment decisions.关键词
