SIRS or not SIRS: Is that the infection? A critical review of the sepsis definition criteria

Abstract

The modern approach to sepsis has focused on creating a global consensus with different criteria to early investigate it in order to reduce the morbidity and mortality associated with this complex entity. Until the third and last consensus of adults (Sepsis-3), the systemic inflammatory response syndrome (SIRS) was the diagnostic pillar used by default for all ages. In Sepsis-3, it was decided to withdraw the SIRS, which generated an international debate about the timing of such change. This narrative review develops the history of the different definitions of sepsis focused on SIRS, their strengths and weaknesses, and the relevance of the different elements that caused the debate. Given the absence of pediatric updates in Sepsis-3, a particular emphasis is placed on the implications for future definitions of sepsis at this stage of life.
