Critical care myopathy in a child

Area of Science:

• Critical care medicine
• Neuromuscular disorders
• Pediatric critical care

Background:

• Critical care myopathy (CCM) is a significant cause of muscle weakness in intensive care units (ICUs).
• It is often underdiagnosed, impacting patient recovery and rehabilitation.
• Understanding risk factors is crucial for early identification and management.

Observation:

• A pediatric case of severe CCM developed in the ICU.
• The patient had newly diagnosed autoimmune hepatitis, potentially increasing susceptibility to corticosteroid and neuromuscular-blocking agent toxicity.
• The patient experienced a complete recovery of muscle strength.

Findings:

• Identified risk factors for CCM in this patient included liver dysfunction, acute lung injury, corticosteroid use, and neuromuscular blockade.
• The case underscores the multifactorial nature of CCM development in critically ill children.
• Complete strength recovery was achieved, suggesting potential for reversibility.

Implications:

• Rheumatology consultants should include CCM in their differential diagnosis for unexplained weakness in critically ill patients.
• Early recognition and evaluation of CCM can lead to improved patient outcomes.
• Further research into CCM prevalence and management strategies in pediatric ICUs is warranted.
