Introduction to multiple organ dysfunction and failure.

Area of Science:

• Critical care medicine
• Veterinary internal medicine
• Pathophysiology

Background:

• Multiple organ dysfunction syndrome (MODS) emerged as a complication of critical care advancements.
• MODS is a primary cause of mortality and resource use in human intensive care units.
• MODS is increasingly recognized in veterinary small animal patients.

Purpose of the Study:

• To review the evolving understanding of MODS pathogenesis.
• To highlight current management strategies for MODS.
• To identify key pathophysiological features of MODS.

Main Methods:

• Literature review of MODS pathogenesis and management.
• Synthesis of information on clinical presentation and features.
• Analysis of the shift in understanding from infection to inflammation.

Main Results:

• The understanding of MODS pathogenesis has shifted from uncontrolled infection to uncontrolled inflammation.
• Current management relies on supportive care, organ function monitoring, and intensive care.
• Prominent features include tissue hypoxia, microvascular thrombosis, increased vascular permeability, and disrupted cell communication.

Conclusions:

• MODS represents a significant challenge in both human and veterinary critical care.
• Effective management requires a comprehensive approach focusing on supportive care and monitoring.
• Further research into the inflammatory pathways of MODS is warranted.
