Percutaneous Electric Nerve Stimulation Clinical Trial
Official title:
Effects of Local Anesthetic or Saline Solution on Peripheral Nerve Stimulation – a Randomised, Double-Blind, Multicenter Study About the Stimulability of Anesthetized Nerves
In this study we want to examine the effect of a small amount of local anesthetic or saline solution on nerve conduction using a peripheral nerve stimulator.
Using electrical nerve stimulation in performing peripheral nerve helps to control the
needle position in relation to the nerve and therefore may increase the likelihood of a
successful nerve block. Defining the minimal stimulating current accepted also may help to
avoid direct contact between nerve and needle or accidental endoneural injection and
subsequent nerve lesion.
In recent years there have been many reports where several nerves, parts thereof or plexuses
have been anesthetised using a multiple injection approach. That is, nerves in close
proximity of each other have been subsequently blocked after using a nerve stimulator to
locate them.
It is not clear though, whether a nerve may already be partially anesthetised in this
situation and whether that would impair the correct use of a peripheral nerve stimulator.
The aim of this study is to examine the excitability of a peripheral nerve after injecting a
small amount of local anesthetic agent or saline solution into the proximity of the nerve.
