There are four pathophysiological patterns of presentation in the Guillain Barré Syndrome (GBS): Demyelinizing form; Acute motor-axonal neuropathy; Acute sensitive-motor axonal neuropathy; and Miller Fisher Syndrome. Absence of electrical excitability of motor nerves (previously referred as complete conduction blockade) is considered as a maniCestation of axonal degeneration of ventral roots or of distal branches of peripherical nerve. Usually, patients without composed muscular action potential in electrophysiological studies performed during the first month of disease, will develop severe debility and cuadriplegia in the peak of clinical course, prolonged "plateau" and long recuperation periods. We report a group of children with Guillain Barré Syndrome (GBS) treated in Roosvelt Institute at Bogotá, Colombia, in whom the common electrophysiological pattern was the absence of electrical excitability of motor nerves. Ah of them also displayed uniform clinical findings at the onset of symptoms as well as during the clinical course.
