Polyneuropathies in critically ill patients: a prospective evaluation.
OBJECTIVE
To determine the incidence, severity and course of polyneuropathies in patients with sepsis or systemic inflammatory response syndrome combined with multiple organ failure.


METHODS
Prospective study.


METHODS
Division of Intensive Care Medicine of the Department of Anesthesiology and Intensive Care and Intensive Care Unit of the Department of Neurology, University Hospital Innsbruck, Austria.


METHODS
Twenty-two patients between 23 and 77 years old with sepsis or systemic inflammatory response syndrome combined with multiple organ failure fulfilling strict inclusion and exclusion criteria.


METHODS
Clinical neurologic examination and electro myography/nerve conduction velocity measurements during the stay on the Intensive Care Unit and 2-3 months later.


RESULTS
In 9 of the 22 patients signs of polyneuropathy were found at the initial clinical investigation and in 7 patients at the follow-up investigation. Electrophysiologic investigation revealed signs of polyneuropathy in 18 patients initially and in 11 patients 2-3 months later.


CONCLUSIONS
In our patient population the frequency of the development of polyneuropathy was high (81.8%). Electrophysiologic investigation is superior to clinical neurologic examination in the detection of polyneuropathies.
