[Intensive Care Unit-Acquired Weakness]

Area of Science:

• Critical Care Medicine
• Neuromuscular Disorders
• Rehabilitation

Background:

• Intensive care unit (ICU)-acquired weakness is a frequent neuromuscular complication in critically ill patients.
• It is associated with prolonged mechanical ventilation, systemic inflammatory response syndrome, and metabolic alterations, accelerating muscle wasting.
• Clinical features include generalized muscle weakness, diaphragmatic dysfunction, and functional decline.

Purpose of the Study:

• To provide a comprehensive scientific overview of ICU-acquired weakness.
• To cover its definition, etiology, diagnosis, impacts, and intervention strategies.
• To enhance frontline staff understanding for timely patient management.

Main Methods:

• This mini-review synthesizes current scientific literature on ICU-acquired weakness.
• It examines etiological factors, diagnostic approaches, and clinical consequences.
• Potential intervention strategies are discussed.

Main Results:

• ICU-acquired weakness presents as acute generalized muscle weakness post-critical illness onset.
• Diaphragmatic dysfunction, post-extubation dysphagia, and functional decline are common sequelae.
• Recovery is often lengthy and challenging, necessitating a multidisciplinary approach.

Conclusions:

• ICU-acquired weakness significantly impacts patient recovery and requires proactive management.
• Understanding the condition's multifaceted nature is key for effective intervention.
• Multidisciplinary team involvement is essential for optimizing functional outcomes in ICU survivors.
