Abstract: Objective To monitor the incidence of pulmonary infection after cardiac surgery by target monitoring for reducing the incidence of postoperative pulmonary infection. Methods Surgical targets monitoring was used to follow 425 patients undergoing cardiac surgery in a tertiary general hospital from January 2017 to December 2018. There were 25 cases of postoperative pulmonary infection, and the infection rate was 5.88%. From 2019 and 2020, the PDCA cycle mode was applied to compare the rate of pulmonary infection after cardiac surgery. Results In 2019, 11 cases in 265 patients with cardiac surgery had postoperative pulmonary infection, and the infection rate was 4.15%; In 2020, 6 cases in 200 patients with cardiac surgery had postoperative pulmonary infection, and the infection rate was 3%. Conclusions Through surgical target monitoring, it is found that the application of the PDCA cycle mode can jointly participate in the prevention and control of nosocomial infection with multiple disciplines, and continuously improve the quality. At the same time, it can effectively reduce the incidence of pulmonary infection after cardiac surgery, and greatly improve the life and quality of life of patients.
