Hypermetabolism and Nutritional Support in Sepsis.

Area of Science:

• Surgical Metabolism
• Critical Care Medicine
• Trauma Surgery

Background:

• Surgical metabolism historically focused on nutrient shifts (electrolytes, carbohydrates, fats, amino acids) to manage proteolysis after injury and tumor growth.
• This research underpins current methods for maintaining homeostasis during major surgery and trauma.

Purpose of the Study:

• To review the current understanding of surgical metabolism, particularly in the context of sepsis.
• To highlight the importance of metabolic support in managing catabolic stress and its impact on organ function.
• To discuss the evolving paradigms and future directions in surgical metabolism research.

Main Methods:

• Comprehensive review of the English-language scientific literature on surgical metabolism.

Main Results:

• The field of surgical metabolism has seen reduced focus due to advances in inflammation research (cytokines, chemokines).
• Understanding metabolic responses to catabolic stress is vital for patient management after injury, despite a lack of evolutionary precedent.
• Nutritional strategies to modulate the immune response and promote recovery in surgical patients remain a subject of debate, especially concerning sepsis.

Conclusions:

• The review discusses shifts in the foundational principles of surgical metabolism research.
• Future technological advancements may reinvigorate interest in surgical metabolism among researchers.
