The incidence of polyneuropathy in critically ill patients

F.S.S. Leijten and A.W. de Weer (The Hague)

A prospective study was undertaken during one year including all patients at an intensive care unit who were mechanically ventilated and had either ARDS (Adult Respiratory Distress Syndrome) a&/or septic syndrome. According to a protocol, 18 patients were examined neurologically and electromyograp~ically.

Pathological studies were done in 4 patients who died. In 90 per cent of cases, a polyneuropathy was found. Its clinical importance lies in the prolonged period of weaning from ventilation and of subsequent revalidation.

Twenty six patients with a subacute polyneuritis, starting with cranial nerve dysfunction and meeting the criteria of the Guillain Barre syndrome (GBS) were included in a retrospective multicenter study. The results were compared with those of the Dutch GBS trial (N = 147).

The UDGBS was subdivided in an ophthalmopleg- ic (N = 16) and a lower cranial nerve variant (N = 9). Ataxia. areflexia, disturbances of swallowing and other cranial nerves and limb muscles justified the proposed UDGBS subclassification. Both showed a similar pattern of recovery as GBS.

The same antecendent infections as GBS, includ- ing Campylobacter, are noted. Age proved to be a

signi~cant prognostic factor especially conside~ng the number of patients with artificial respiration (72% over 50 years versus 12% under 50 years) and ADL-independency after 4 weeks (80% versus 25%).

On the other hand the relative frequency of the involved cranial nerves is different from that of GBS. In particular the cranial nerves 3,4,6 (GBS 1527%) UDGBS 70-85%) and 10, 11 (CBS 12%, UDGBS 28-33%) were relatively more affected. Remarkable is that the predominant involvement of the short mo- tor cranial nerves and the relatively short nerves to the proximal arm muscles are inconsistent with a random distribution of lesions; it suggests specific but as yet unknown mechanisms.
