Q: What are the four major components of  Critical Illness Polyneuropathy (CIP)?


Answer:  Critical Illness Polyneuropathy (CIP) is a distinct entity from Critical Illness Myopathy (CIM) - though both may usually exists together. Critical Illness Polyneuropathy (CIP) has four distinct properties which distinguish it from CIM.

• limb muscle weakness which proceeds to atrophy, 
• decrease  or absent deep tendon reflexes, 
• loss of distal peripheral sensation, and 
• relative preservation of cranial nerve function
