简要总结

The traditional model of localizing a nerve for blockade is using a peripheral nerve stimulator, PNS. Recent advances in UltraSound technology has allowed UltraSound to guide nerve blockade. However despite excellent visualization nerve block success has not significantly improved. I aim to show that this is because the PNS stimulation of a nerve is more than a proximity response as thought but a correct fascial plane response and hence the high success rate of this blind approach.
