Abstract: Hospital acquired infection (HAI) is one of the common complications of hospitalized patients and poses a serious threat to public health worldwide, which causes an exacerbation, prolonged hospitalization and increased medical costs. Because of higher illness severity and more invasive operations, patients in neurosurgical intensive critical unit (NICU) are more susceptible to HAI such as hospital acquired pneumonia (HAP) and surgical site infection (SSI), leading to the increase of mortality. Therefore, the prevention and treatment of HAI is an important challenge during the treatment of diseases in NICU. In this paper, we summarized the common types, pathogenic characteristics, prevention measures and antimicrobial treatment of HAI in NICU, aiming to provide ideas and reference on HAI treatment for medical personnel in NICU.
