Neuromuscular Ultrasound in Intensive Care Unit-Acquired Weakness: Current State and Future Directions

Area of Science:

• Critical Care Medicine
• Neurology
• Diagnostic Imaging

Background:

• Intensive care unit-acquired weakness (ICUAW) is a common complication in critically ill patients, leading to muscle atrophy and functional disability.
• Assessing ICUAW is difficult due to sedation, delirium, and cognitive impairment, limiting traditional methods like manual muscle testing.
• Existing alternative diagnostic methods (biopsies, EMG, biomarkers) are often invasive, time-consuming, and impractical for routine ICU use.

Purpose of the Study:

• To review the current scientific literature on the application of neuromuscular ultrasound (NMUS) in diagnosing and monitoring Intensive Care Unit-Acquired Weakness (ICUAW).
• To highlight the diagnostic value and potential of NMUS as a non-invasive tool in the context of ICUAW.
• To discuss the current status and future prospects of NMUS in critical care settings.

Main Methods:

• This narrative review systematically searched and analyzed recent scientific literature focusing on neuromuscular ultrasound (NMUS) in Intensive Care Unit-Acquired Weakness (ICUAW).
• The review synthesized findings from studies investigating the use of NMUS for detecting and monitoring muscle and nerve alterations in critically ill patients.
• Emphasis was placed on evaluating NMUS as a compliance-independent diagnostic tool.

Main Results:

• Neuromuscular ultrasound (NMUS) has demonstrated significant diagnostic value in various neuromuscular diseases.
• In the context of ICUAW, NMUS can effectively detect and monitor changes in muscles and nerves.
• Preliminary evidence suggests NMUS may aid in predicting patient outcomes in critical care.

Conclusions:

• Neuromuscular ultrasound (NMUS) is a promising, non-invasive, and bedside-accessible diagnostic tool for Intensive Care Unit-Acquired Weakness (ICUAW).
• NMUS offers a practical alternative to invasive methods for assessing muscle and nerve integrity in critically ill patients.
• Further research into NMUS applications could enhance the management and prognostication of ICUAW.
