Fluid Bolus Therapy in Pediatric Sepsis: Current Knowledge and Future Direction

Area of Science:

• Pediatric Critical Care Medicine
• Pediatric Infectious Diseases
• Pediatric Resuscitation Science

Background:

• Sepsis is a significant cause of child morbidity and mortality, with an 8% prevalence in pediatric intensive care units.
• Fluid bolus therapy (FBT) has been a cornerstone of septic shock resuscitation for two decades, yet supporting evidence is limited.
• Emerging evidence suggests potential harm from FBT, prompting re-evaluation and interest in fluid-restrictive strategies.

Purpose of the Study:

• To review the current understanding of fluid bolus therapy in pediatric sepsis.
• To explore the physiological and hemodynamic responses to FBT in children.
• To identify knowledge gaps and future research directions for FBT in pediatric sepsis.

Main Methods:

• Literature review of existing studies on fluid bolus therapy in pediatric sepsis.
• Analysis of current evidence regarding the efficacy and safety of FBT.
• Discussion of the complexities in studying FBT, including physiological responses and monitoring limitations.

Main Results:

• The evidence base for current FBT guidelines is derived from limited data, including animal and case-control studies.
• The physiological and hemodynamic effects of FBT in children are not well-characterized.
• Assessing circulatory status in pediatric sepsis relies on non-specific clinical signs and limited monitoring.

Conclusions:

• A deeper understanding of FBT's physiological impact and potential harms in pediatric sepsis is crucial.
• Further research is warranted to optimize fluid management strategies in pediatric septic shock.
• This review highlights the need for improved methodologies and targets for studying FBT in critically ill children.
