Why Use NIM TriVantage™ EMG Tubes?

Even experienced surgeons find it difficult to visually identify the recurrent laryngeal nerve (RLN) or vagus nerve during thyroid surgery and other neck dissections. Studies show that the rate of RLN injury is under-estimatedand intraoperative nerve monitoring of the RLN is recommended as a risk-minimizing tool.2

NIM TriVantage™ EMG tubes provide an open airway for patient ventilation and intraoperative nerve monitoring of both vocal cords. If nerve function changes, the NIM™ system alerts you with visual and audible tones to help reduce the risk of patient injury.6

NIM™ TriVantage EMG ENDOTRACHEAL TUBE

The NIM TriVantage™ EMG Tube is a standard size, non-reinforced, DEHP-free PVC tube that features smooth, conductive silver ink electrodes and a cross-band to guide placement. It has reduced sensitivity to rotation and movement while offering increased EMG responses that facilitate improved nerve dissection.  

Together with the NIM™ system, a properly positioned NIM™ EMG tube can reduce the risk of injury to your patient by helping you to:6

  • Identify the recurrent laryngeal or vagus nerves5
  • Control manipulation during dissection7
  • Verify the integrity of the nerve prior to surgical closure8

Only NIM TriVantage™ EMG tubes are tested and validated for use with NIM™ nerve monitors.
