Critical illness-associated limb and diaphragmatic weakness

Area of Science:

• Critical care medicine
• Neuromuscular disorders
• Pulmonary medicine

Background:

• Critical illness weakness (CIW) and critical illness associated diaphragmatic weakness (CIDW) are prevalent complications in intensive care units (ICUs).
• These conditions share risk factors but possess distinct pathophysiological mechanisms and impact patient outcomes differently.
• Underdiagnosis is common due to diagnostic challenges, leading to increased morbidity and mortality.

Approach:

• This review synthesizes current evidence on the diagnosis, prevention, and treatment of CIW and CIDW.
• It examines emerging diagnostic techniques suitable for clinical practice.
• It summarizes recent advancements in therapeutic interventions and preventative strategies.

Key Points:

• Diagnosis of CIW is primarily clinical and difficult in the ICU setting.
• CIDW diagnosis is complex and not easily performed at the bedside.
• Novel diagnostic tools and therapeutic approaches are being developed to address these challenges.
• Effective management of CIW and CIDW is crucial for improving short- and long-term patient outcomes.

Conclusions:

• Clarifying diagnostic uncertainties and developing effective monitoring techniques are essential for managing CIW and CIDW.
• Further research into targeted therapeutic interventions is needed.
• Improving the diagnosis and management of CIW and CIDW can significantly reduce patient complications and enhance recovery.
