Intraoperative Nerve Stimulation: A Simple, Effective, and Inexpensive Alternative to Standard Devices

Abstract

Many surgical procedures require intraoperative stimulation of peripheral nerves. Using a pair of conventional bipolar forceps and an anesthetic impulse generator (Stimlocator, Model SL3, B. Braun Australia Pty Ltd, Australia), we have developed a simple, effective, and inexpensive alternative to standard nerve stimulation devices that enables the accurate localization of motor fascicles intraoperatively. Bipolar forceps provide better control than a monopolar electrode, as the current generated across the nerve fibers generates an action potential that is then propagated down the axon. This inexpensive and reusable device is routinely used at Royal Children's Hospital, Melbourne, and its ef..
