Metabolic acidosis in sepsis

Area of Science:

• Critical Care Medicine
• Nephrology
• Pathophysiology

Background:

• Metabolic acidosis is prevalent in critically ill septic patients.
• Acidosis can stem from sepsis pathophysiology or patient management, particularly fluid resuscitation.
• Chloride-associated acidosis is a frequent concern, potentially exacerbated by fluid therapy.

Purpose of the Study:

• To explore the relationship between metabolic acidosis and septic syndromes.
• To investigate the impact of acidosis modulation on inflammatory mediators and cardiovascular function.
• To evaluate strategies for managing metabolic acidosis in septic patients.

Main Methods:

• Review of existing literature on metabolic acidosis in sepsis.
• Analysis of experimental findings on acidosis modulation.
• Discussion of treatment strategies, including fluid resuscitation choices.

Main Results:

• The severity of metabolic acidosis correlates with poor clinical outcomes in sepsis.
• Experimental data suggest acidosis affects inflammatory mediator release and cardiovascular function.
• Chloride-poor balanced solutions may prevent acidosis worsening during fluid resuscitation.

Conclusions:

• The exact causal role of acidosis in septic syndromes requires further investigation.
• Acidosis management is crucial in critically ill septic patients.
• Chloride-poor balanced solutions represent a promising approach to mitigate acidosis during fluid resuscitation.
