Sepsis in children

Have a low threshold for suspecting sepsis as the initial clinical presentation of sepsis in children may be nonspecific (especially in younger age groups).

Given the time-critical nature of severe sepsis and septic shock, when sepsis is suspected on clinical grounds it is usually best to initiate sepsis investigations and treatment, including administering antibiotics and fluid resuscitation. These should continue until sepsis has been excluded.

Progression to organ failure and shock is often very rapid, so early recognition and treatment is crucial.

Empiric broad-spectrum antibiotic therapy (based on the most probable pathogens) should be administered as soon as possible, and always within the first hour following recognition of severe sepsis.

Other treatments are primarily supportive, and should be delivered according to internationally recognized consensus-based guidelines.

Sepsis is a clinical syndrome resulting from a dysregulated immune response to infection.[1]Bone RC. The sepsis syndrome: definition and general approach to management. Clin Chest Med. 1996 Jun;17(2):175-81. http://www.ncbi.nlm.nih.gov/pubmed/8792059?tool=bestpractice.com It is characterized by derangements in multiple pathobiologic processes, which may lead to widespread tissue injury.[2]Angus DC, van der Poll T. Severe sepsis and septic shock. N Engl J Med. 2013 Aug 29;369(9):840-51. http://www.nejm.org/doi/full/10.1056/NEJMra1208623 http://www.ncbi.nlm.nih.gov/pubmed/23984731?tool=bestpractice.com It encompasses a clinical spectrum of severity including severe sepsis, septic shock, and multiorgan failure.[3]Goldstein B, Giroir B, Randolph A; International Consensus Conference on Pediatric Sepsis.

Causes of child mortality. 2017 [internet publication].

Traditionally, sepsis has been defined based on the presence or absence of the systemic inflammatory response syndrome (SIRS). In adults, the definitions of sepsis were updated in 2016, moving away from the SIRS definition and removing the term "severe sepsis".[3]Goldstein B, Giroir B, Randolph A; International Consensus Conference on Pediatric Sepsis.

Pediatr Crit Care Med. 2005 Jan;6(1):2-8. http://www.ncbi.nlm.nih.gov/pubmed/15636651?tool=bestpractice.com

At present there are no revisions to the international consensus definition of pediatric sepsis, which dates from 2005.[3]Goldstein B, Giroir B, Randolph A; International Consensus Conference on Pediatric Sepsis. International pediatric sepsis consensus conference: definitions for sepsis and organ dysfunction in pediatrics. Pediatr Crit Care Med. 2005 Jan;6(1):2-8. http://www.ncbi.nlm.nih.gov/pubmed/15636651?tool=bestpractice.com However, in 2020 the Surviving Sepsis Campaign proposed a definition for septic shock in children: "severe infection leading to cardiovascular dysfunction (including hypotension, need for treatment with a vasoactive medication, or impaired perfusion)".[5]Weiss SL, Peters MJ, Alhazzani W, et al.
