Critical illness neuromuscular abnormalities.

Area of Science:

• Critical care medicine
• Neurology
• Intensive care unit (ICU) acquired neuromuscular abnormalities (CINMAs)

Background:

• CINMAs are common in critically ill patients, prolonging respiratory failure and leading to chronic critical illness.
• Distinguishing between different neuromuscular disease entities (NMDs) is challenging due to diverse and overlapping etiologies.
• Critical illness polyneuropathy (CIP) is the most studied CINMA, representing a peripheral nervous system manifestation of multiple organ dysfunction syndrome (MODS).

Purpose of the Study:

• To highlight the significance of CINMAs in critically ill patients.
• To discuss the diagnostic challenges and prognostic implications of CINMAs.
• To outline current and potential future management strategies for CINMAs.

Main Methods:

• Review of existing literature on CINMAs, focusing on CIP.
• Analysis of clinical presentation, electrophysiologic findings, and outcomes.
• Discussion of supportive care and potential preventative measures.

Main Results:

• Patients with CIP, especially with severe nerve dysfunction, face prolonged rehabilitation and high mortality.
• Diagnosing CINMAs offers valuable prognostic information, despite the lack of definitive treatments.
• Supportive care in the chronic critical illness (CCI) phase includes preventing complications, nutritional support, and physical therapy.

Conclusions:

• Early recognition of CINMAs is crucial for improving outcomes in CCI patients.
• Preventative strategies may involve immunoglobulin, nerve growth factors, or strict glycemic control.
• Comprehensive supportive care facilitates recovery, enabling patients to return home with better functional levels and quality of life.
