Pediatric emergency pre-examination triage plays a vital role in pediatric emergency treatment. At present, many international emergency triage systems have been standardized, but there is still a lack of unified standard emergency pediatric triage system in China. Some hospitals in China are changing from "branch triage" to "hierarchical triage" mode, and begin to try to establish triage tools suitable for their own conditions. The purpose of this paper is to briefly introduce the commonly used pediatric emergency triage assessment tools and their clinical applications, to provide useful reference for improving pediatric emergency pre-detection triage.
