"Metabolic staging" after major trauma - a guide for clinical decision making?

Area of Science:

• Trauma pathophysiology
• Metabolic alterations
• Inflammatory response

Background:

• Major trauma triggers a hyperinflammatory, hypercatabolic state with increased energy needs.
• Early recognition of this metabolic state is vital for effective nutritional management.
• Enteral immunonutrition aims to mitigate adverse effects of inflammation and catabolism, reducing complications.

Discussion:

• Metabolic staging categorizes post-trauma phases (ischemia/reperfusion, leukocytic, angiogenic phenotypes).
• This staging considers distinct inflammatory phases and metabolic phenotypes.
• Adapting metabolic control and nutritional support based on these stages is proposed.

Key Insights:

• Post-traumatic metabolic changes are complex, involving hyperinflammation and hypercatabolism.
• Early nutritional intervention, particularly enteral immunonutrition, is essential.
• Metabolic staging offers a framework for personalized post-trauma care.

Outlook:

• Further research is needed to determine the clinical impact of metabolic staging.
• Optimizing metabolic control and nutritional support tailored to metabolic phenotypes is a future direction.
• Investigating the long-term outcomes of metabolic staging and adapted nutritional strategies is warranted.
