It is no longer necessary to disconnect the anesthesia nerve stimulator during electrosurgery procedures.* EZ Stim is the first commercially available electro surgery certified peripheral nerve locator and stimulator. EZ Stim can be used as peripheral nerve stimulator to monitor neuromuscular transmission to determine the effectiveness of muscle relaxants or as a nerve locator to help locate the targeted fascicules when delivering regional anesthesia.
