Summary

The aim of this study is to compare two distinct modes of NIM Vital application in thyroid surgery: NerveTrend vs. NerveAssure mode with respect to prevalence of early postoperative RLN injury.

The hypothesis explored in this study is that NerveTrend mode may be not inferior than NerveAssure mode in intraoperative identification of impending neural injury and in prognostication of postoperative glottis function in monitored bilateral thyroid surgery. Hence, NerveTrend mode may be considered a bridge between i-IONM and NerveAssure modes, and particularly in health care environments with limited financial resources it can be considered a substantial step forward representing a modern alternative to the NerveAssure technique.

A prospective, randomized study with 2 arms: NeveTrend vs. NerveAssure mode (n=132 patients and 264 nerves at risk, each).

The primary outcome measure is prevalence of recurrent laryngeal nerve (RLN) injury (%) on postoperative day 1 assessed by direct laryngoscopy.

Interventions

DEVICE

Neuromonitoring of the recurrent laryngeal nerves

The NIM Vital system (Medtronic, Jacksonville, US) operates with surface electrodes integrated with an endotracheal NIM TriVantage tube 7.0-8.0 in diameter, which is inserted by an anesthetist between the vocal folds under direct vision during intubation. The standardized technique of IONM RLNs wll be used, including initial vagal response evaluation at the beginning and final vagal response evaluation at the end of surgery (IONM = L1+V1+R1+R2+V2+L2) according to the recommendations formulated by the International Intraoperative Neural Monitoring Study Group. The nerves will be stimulated using a monopolar electrode and the interrupted stimulation technique at 1mA, 100ms impulse duration and 4Hz frequency. In case of the bifurcated RLN nerves, the assessment includes post-stimulation response of each nerve branch. Adduction of the vocal folds is detected by the endotracheal tube electromyography and abduction by finger palpation of muscle contraction in the posterior cricoarytenoid.
