Description of Event or Problem

IT WAS REPORTED THAT DURING LYMPH NODE DISSECTION PROCEDURE AFTER SETTING THE APS ELECTRODE TO THE VAGUS NERVE, AN ATTEMPT WAS MADE TO OBTAIN A BASELINE, HOWEVER, STIMULATION COULD NOT BE ACHIEVED DUE TO THE LEAD-OFF DISPLAY. UPON CHECKING THE APS ELECTRODE, THE ELECTRODE WAS NOT EXPOSED FROM THE TIP OF THE SILICONE PART, SO IT WAS BURIED. THIS RESULTED IN A POWER FAILURE. A NEW APS ELECTRODE WAS TAKEN OUT, AND MONITORING BECAME POSSIBLE WITHOUT ANY PROBLEMS. THERE WAS NO PATIENT IMPACT.
