Fluid Resuscitation for Suspected Sepsis in Paediatric Emergency Departments

Septic Shock

Paediatric sepsis, SSC-2020, fluid bolus therapy

With 25.2 million children affected and 3.4 million deaths in 2017, paediatric sepsis is the leading cause of under-five mortality worldwide and has recently been described as significant global health threat by the World Health Organization. In addition to early antibiotics, fluid bolus therapy (FBT) is one of the cornerstones of management, due to the theoretical improvement of cardiac output, oxygen delivery and organ perfusion. In the absence of a consensual and operational definition to date, the latest international guidelines of the Surviving Sepsis Campaign 2020 (SSC-2020), refers to children (≥ 37 weeks gestation at birth to 18 years old) with severe infection leading to cardiovascular (i.e., septic shock) or non-cardiovascular organ dysfunction (i.e., other sepsis-associated organ dysfunction or former severe sepsis). The SSC-2020 specifies the modalities for paediatric sepsis management, particularly concerning FBT, with, for example, the preferential use of balanced crystalloids, and a target volume of 40-60ml/kg at one hour of recognition using boluses of 10-20ml/kg in children who have access to a paediatric intensive care unit (PICU) in their health system. Further, it is now well established that compliance with international guidelines is associated with improved outcomes in paediatric sepsis. Despite the importance of awareness and implementation of the SSC-2020, there are, to our knowledge, no studies evaluating its application in children. We prospectively conducted the Fluid Resuscitation for Suspected Sepsis in Paediatric Emergency Departments (FRESSPED) study in 25 hospitals over five weeks between November 2021 and March 2022, whose principal objective was to assess doctors adherence to the SSC-2020 guidelines when performing FBT in infants and children with suspected sepsis in French paediatric emergency departments.

FRESSPED study was conducted over 5 weeks, the last week of each month, between November 2021 and March 2022 (11/29 - 12/05 ; 12/27 - 01/02 ; 01/24 - 30/01 ; 02/21 - 02/27 ; 03/21 - 03/27). Patients were followed up one month after inclusion, extending the study period until midnight on 28 April 2022. FRESSPED study was conducted in three stages : 1. Evaluation of usual fluid bolus therapy practice in infants and children with suspected sepsis in French paediatric emergency departments, through the prospectively anonymous completion of a paper case report form (CRF) designed to be completed in less than 5 minutes, within 72 hours of inclusion, by each doctor in one of the participating centers caring for an eligible patient 2. Questioning of participating doctors at the end of the 5-week prospective data collection period, to explore the underlying reasons of doctors non-adherence to the SSC-2020 guidelines. It will take the form of a short, anonymized and blinded of centers outcomes, online survey to assess attitudes and knowledge, without inter-center or inter-individual comparisons (except for doctors seniority) 3. Description of characteristics and outcomes of included patients, by consultation, up to 1 month after inclusion, of data collected in routine care (patient chart) by the lead researcher (Julian San GEROTEO). In addition to the above criteria, the suspicion of sepsis was confirmed retrospectively in doubtful or non-documented cases or those without microbiological documentation, using an adjudication committee composed of two medical experts particularly important in the absence of a gold standard definition of paediatric sepsis to date.
