We had some great input and debate from students on this question of the day from a nero exam. Congrats to those of you who correctly guessed it as Guillain Barre Syndrome.
Now check your hypothesis against the clinical signs:
|Tone||Any sign of UMN lesion or hypotonia (cerebellar?) NO
But there is some reduced tone in the left arm:
|Power||He is weak and its come on
over the past few days: this is classical of GBS: an ascending peripheral
motor and sensory poylneuropathy.
|Coordination||Normal: as expected|
|Sensation||Normal: So can it still be
YES! The sensory signs are often vary vague: there may be only back
|Reflexes||Clinical tip: no reflexes
Auggests a lower motor neurone problem. Could it me MND? Very unlikely:
there’s only LMN signs and the onset of the illness is too acute.
|Other things||GBS: measure the Forced Vital Capacity:
If this is low: the patient may need ventilation.
Also remember: cardiac conduction deficits (monitor the patient on
Remember FVC monitoring in GBS.
