儿童早期预警评分在急诊转运中的应用进展

Advances in application of pediatric early warning system score in emergency transport

儿童早期预警评分(pediatric early warning system score,PEWS)是对患儿的体温、血压、心率、呼吸、意识、血氧饱和度及各项生理指标等进行监测,给予评分,以协助医护人员早期识别患儿病情变化的评分系统,具有较高的灵敏度和特异度。此外,PEWS有助于急诊和重症患儿转运,其应用能大幅度降低院内及院外转运风险,优化医护人员配置,促进病情严重患儿的早期识别与治疗。但目前缺乏标准的PEWS评分系统和相关指南,加之基础理论研究有待深入,这些因素都影响了PEWS的定义、实施和有效测量的一致性。因此,该文对PEWS的发展及其在急诊转运中的应用进行综述,以期为提升急诊患儿转运质量提供参考。

Pediatric early warning system(PEWS)monitors the children's temperature,blood pressure,heart rate,respiration,consciousness,oxygen saturation and various physiological indicators to form a score,which helps medical staff to identify the changes of children's condition in the early stage,with high sensitivity and specificity.In addition,PEWS is of great help in the transportation of children under emergent conditions or with critical illness.PEWS application can greatly reduce the risk of in-hospital and out-of-hospital transport,optimize the allocation of medical staff,and promote the early identification and treatment of children with serious conditions.However,the lack of standard PEWS and related guidelines,as well as the limited development of basic theories,can affect the consistency of the definition,implementation and effective evaluation of PEWS.Therefore,this article will review the development of PEWS and its application in emergency transport,so as to provide reference for improving the quality of emergency pediatric transport.
