Patients with infections in the department of critical care medicine have complex sources and diverse sites of infection,which may be associated with multiple pathogenic bacteria and have a high rate of drug resistance,posing a significant challenge to clinical diagnosis and treatment.Infections in the depart-ment of critical care medicine can be divided into two types:hospital acquired infections and non-hospital ac-quired infections,with significant differences in clinical characteristics between the two.This article discusses the relevant concepts,risk factors,pathogenesis,and common characteristics of severe infections such as bloodstream infections,pulmonary infections,intra-abdominal infections,and intracranial infections,as well as diagnostic and treatment plans and prevention and control strategies from the perspectives of hospital ac-quired and non-hospital acquired infections,aiming to provide valuable guidance for the clinical management of critically ill patients.
