Predictive factors and long-term outcome of respiratory failure after Guillain-Barré syndrome.
OBJECTIVE
To analyze predictive factors and long-term recovery in patients with Guillain-Barré syndrome (GBS) who are in need of mechanical ventilation.


METHODS
In this 15-year retrospective study, 77 adult patients were identified with GBS. A comparison was made between the clinical data from patients who required mechanical ventilation and those who did not. Furthermore, the therapeutic outcomes of those 25 patients in need of mechanical ventilation during hospitalization at 1 year were determined using a modified Barthel index. A score below 12 was defined as a poor outcome, whereas a score of 12 or more was good.


RESULTS
The study revealed 32% of patients (25/77) in need of respiratory support during hospitalization. At a follow-up of 1 year among the 25 ventilated patients, 7 patients (28%) had normal or minor signs and symptoms, 6 had unassisted gait, 3 had assisted gait, 6 were wheelchair- or bed-bound, and 3 died. The cause of death was septicemia with septic shock in all 3 cases. Factors that predict respiratory failure in the study GBS patients were disability grade on admission and areflexia. Those ventilated patients who had low maximal inspiratory pressure (PImax) (<14.5 cmH2O) and maximal expiratory pressure (PEmax) (<13.5 cmH2O) values at the time of intubation and the presence of complications after mechanical ventilation inevitably had worse outcomes than those who had not.


CONCLUSIONS
If low values of PImax and PEmax at intubation were detected, aggressive respiratory management, which might include tracheostomy to allow more efficient bronchial clearing, and prevention of complications caused by prolonged course of mechanical ventilation are essential to maximize the potential for survival.
