Guillain-Barre syndrome (GBS) is an acute inflammatory polyneuropathy that
may lead to quadriparesis, ventilatory failure, and autonomic dysfunction.
While significant mortality due to ventilatory failure has been associated
with this syndrome, this complication can now be readily managed. However,
an estimated mortality of 5% to 20% remains attributable to medical
complications (pulmonary embolus, sepsis) and to acute cardiovascular
collapse due to autonomic failure. In this report, detailed sequential
changes in hemodynamic parameters, as measured by Swan-Ganz catheter,
associated with severe autonomic cardiovascular instability in a patient
with GBS are described. Knowledge of changes in these hemodynamic
parameters led to optimal therapy. Long-term Swan-Ganz monitoring in an
intensive care setting may dramatically benefit the critically ill patient
with GBS and cardiovascular autonomic dysfunction, and may help to
eliminate the residual morbidity and mortality associated with this
disease.
