    Abstract
  •   Objective  This study aimed to monitor the incidence of nosocomial pneumonia caused by multidrug-resistant bacteria after thoracic surgery; analyse the risk factors of postoperative pneumonia caused by multidrug-resistant bacteria; develop corresponding prevention, control and intervention measures and reduce the incidence of postoperative pneumonia and multidrug-resistant bacterial infection, thereby accelerating the postoperative recovery of patients.  Methods  A total of 610 patients were admitted to the Department of Thoracic Surgery from 2016 to 2018 and monitored for nosocomial infection, and the incidence of postoperative pneumonia caused by multidrug-resistant bacterial infection and the risk factors associated with infection were analysed. SPSS 20.0 software was used for statistical analysis of data.  Results  A total of 22 strains of Pseudomonas aeruginosa were detected, accounting for 50.00% (22/44), and 8 strains of carbapenem-resistant Acinetobacter baumannii were detected, accounting for 53.33% (8/15). The rate of postoperative pneumonia caused by multidrug-resistant bacterial infection decreased from 3.38% in 2016 to 1.37% in 2018, and single-factor analysis showed the following risk factors: antibiotic use for 14 days, urethral catheter or mechanical ventilation. The length of stay in intensive care unit, ASA score acuity Ⅱ and use of antimicrobial agents are the main risk factors (all P < 0.05). Logistic multifactor analysis showed that only antibiotic use was the related independent risk factor of postoperative pneumonia caused by multidrug-resistant bacterial infection.  Conclusion  The main risk factors of postoperative pneumonia caused by multidrug-resistant bacterial infection can be found through effective nosocomial infection monitoring and risk factor analysis, thereby reducing the incidence of postoperative pneumonia caused by multidrug-resistant bacterial infection.
