Acquired respiratory failure in critically ill patients.
With increasing survival rates from acute medical or surgical emergencies a new form of peripheral neuropathy, CIP, has been recognized. CIP can be seen only in patients who are considered to be critically ill; therefore, it invariably occurs in the ICU. Typically, initial symptoms begin with transient (hours to a few days) septic encephalopathy followed by generalized weakness, manifested in weaning failure, limb weakness and hyporeflexia. Diagnosis is confirmed by an EMG. CIP should be considered in any elderly patient with sepsis and prolonged respiratory muscle weakness. Prognosis is poor in severe cases, in which the EMG also shows severe axonal degeneration. In milder forms, fair to good recovery is expected within weeks. Management includes treatment of sepsis, normalization of failing organ function, physical therapy and proper nutrition.
