Myopathies in the intensive care unit
1Department of Clinical Neurosciences, University of Calgary, Alberta, Canada.
Summary
Intensive care unit (ICU) myopathies are either preexisting or newly acquired. Newly developed ICU myopathies, potentially linked to corticosteroids, can cause acute respiratory failure.
Area of Science:
- Critical care medicine
- Neurology
- Pathology
Background:
- Myopathies in the intensive care unit (ICU) are categorized as preexisting or newly acquired.
- Preexisting myopathies, such as myotonic dystrophy, can increase susceptibility to respiratory failure post-surgery.
- Newly acquired ICU myopathies include acute necrotizing myopathy, thick filament myopathy, and acute steroid myopathy.
Purpose of the Study:
- To review the classification and potential causes of myopathies developing in the ICU.
- To highlight the role of specific agents in the development of these conditions.
Main Methods:
- Literature review of studies on ICU-acquired myopathies.
- Analysis of contributing factors, including medications.
Main Results:
- Myotonic dystrophy is an example of a preexisting condition predisposing to critical illness complications.
- Acute necrotizing myopathy of the ICU, thick filament myopathy, and acute steroid myopathy are key entities of newly acquired ICU myopathies.
- Corticosteroids and nondepolarizing muscle relaxants are implicated in the pathogenesis of acquired ICU myopathies.
Conclusions:
- Understanding the types and causes of ICU myopathies is crucial for patient management.
- Further research into the mechanisms and treatments for these myopathies is warranted.
