An Improved Recurrent Laryngeal Nerve-Monitoring Device: Technical Note for Nim Vital™

초록

A new device for monitoring the laryngeal nerves during thyroid surgery has been developed. NIM Vital (TM) (Medtronic Xomed, Inc., Jacksonville, FL, USA) incorporates (a) a new wireless design, (b) NIM Nerve-Trend (TM) (Medtronic Xomed) EMG reporting, (c) intelligent noise-reduction technology that suppresses artifacts, (d) smart troubleshooting pop-up alerts, and (e) NIM Nervassure T (Medtronic Xomed) for continuous monitoring. This device offers enhanced stability and flexibility for both intermittent and continuous laryngeal nerve monitoring. The new NIM NerveTrend (TM) EMG reporting makes it possible to track the recurrent laryngeal nerve condition throughout a procedure, even when using intermittent nerve monitoring. During both continuous and intermittent monitoring, green, yellow and red status bars provide visual information and associated tones provide audible cues, making it easy to monitor nerve function and interpret EMG trends. This new tool for laryngeal nerve monitoring has the potential to augment nerve dissection during surgery. Measurements of long-term outcome are needed to establish their efficacy.
