Epidemiological Features of Sepsis in Children

《国际儿科脓毒症与脓毒性休克共识标准》(Phoenix标准)将脓毒症定义为感染引发的危及生命的脏器功能不全，填补了既往Sepsis-3未覆盖儿童群体的空白。本文从流行病学角度，系统综述了儿童脓毒症的病原学特征、发病率趋势及预后。The “International Consensus Criteria for Pediatric Sepsis and Septic Shock” (Phoenix Criteria) defines sepsis as a life-threatening organ dysfunction caused by infection, addressing the gap left by Sepsis-3 which did not cover the pediatric population. This article systematically reviews the etiological characteristics, incidence trends, and prognosis of pediatric sepsis from an epidemiological perspective.
