CIM

Q: Critical Illness Myopathy (CIM) affects more? (select one)

 A) proximal muscles
 B) distal muscles


Answer: A

CIM is very common and still an under-recognized disease in ICU. After few days in ICU, it may become the most common cause of failure to wean from mechanical ventilation. The most common presenting symptom is flaccid quadriparesis which affects proximal more than distal muscles. Facial muscle weakness is also common but usually, go undiagnosed. The best differential diagnosis is due to the fact that this facial weakness mostly spares extraocular muscle.
