Summary
The median as well as the ulnar nerve may be used effectively in the evaluation of neuromuscular blockade with the peripheral nerve stimulator. Both ulnar and median nerve stimulation produce flexion of the fingers. For maximum neural stimulation either during the routine use of the peripheral nerve stimulator or when it is used as an aid to peripheral nerve block, the negative pole should be attached to the exploring needle or over the nerve to be stimulated.
Résumé
Le nerf médian, tout comme le cubital (que ľon utilise habituellement), peut être utilisé pour évaluer un bloc neuro-musculaire avec un stimulateur nerveux périphérique. La réponse à la stimulation de ľon ou de ľautre nerf est une flexion des doigts. Le pôle négatif devrait être placé de routine sur ľélectrode exploratrice ou sur le nerf à stimuler, ce qui permet ďobtenir une stimulation maximale.
