AbstractGuillain-Barré Syndrome is the leading cause of nontraumatic acute paralysis in industrialized countries. About 30% of patients have respiratory failure requiring intensive care unit (ICU) admission and invasive mechanical ventilation. Progressive weakness of both the inspiratory and the expiratory muscles is the mechanism leading to respiratory failure. Aspiration pneumonia and atelectasis are common consequences of the bulbar muscle weakness and ineffective cough. The classical signs of respiratory distress occur too late to serve as guidelines for management, and measurements of vital capacity and static respiratory pressures are useful to determine the best times for starting and stopping mechanical ventilation. Several factors present at admission and during the ICU stay are known to predict a need for invasive mechanical ventilation. They include rapidly progressive motor weakness, involvement of both the peripheral limb and the axial muscles, ineffective cough, bulbar muscle weakness, and a rapid decrease in vital capacity. Specific treatments (plasma exchange and intravenous immunoglobulins) have decreased both the number of patients requiring ventilation and the duration of ventilation. The need for mechanical ventilation is associated with residual functional impairments, although all patients eventually recover normal respiratory muscle function.
