随着医疗水平的不断进步,各种侵入性检查和操作也不断增加,使得感染风险相应加大[1]。此外,中国由于早期对抗生素管理不规范,导致耐药菌群不断增加,也增大了患者感染耐药菌的风险。在重症监护室中,感染耐药菌往往是致命的,会严重影响ICU患者的生命健康[2]。为了减少多重耐药菌(MDRO)的出现以及尽可能避免重症患者发生院内感染,国家颁布了多种相关指南和规范,但目前重症患者发生院内感染的现状仍不
With the continuous improvement of medical care, various invasive examinations and operations have been continuously increased, resulting in a corresponding increase in the risk of infection [1]. In addition, due to the non-standardization of antibiotic management in China in the early stage, the population of drug-resistant bacteria has been continuously increasing, which increases the risk of patients being infected with drug-resistant bacteria. In intensive care units, infections with resistant bacteria are often fatal and can seriously affect the health and well-being of ICU patients [2]. In order to reduce the emergence of multidrug-resistant bacteria (MDRO) and prevent nosocomial infections in critically ill patients as much as possible, various relevant guidelines and norms have been promulgated in the country. However, the current status of nosocomial infections in critically ill patients is still not
