Ultrasound in CIM/CIP

Q: Muscle ultrasound in Critical Illness Myopathy (CIM) and Critical Illness Polyneuropathy (CIP) will show? (select one) 

 A) increased echogenicity 
 B) decreased echogenicity 


Muscle ultrasound has a good prognostic value in CIM/CIP.  Increased echogenicity of major muscles like biceps, forearm, or mid-thigh muscles is found to be associated with a lower chance of discharge to home. It can be a useful tool to predict CIM/CIP in ICU patients with a sensitivity of 82 percent and specificity of 57 percent.
