AbstractObjective:The proper positioning of the Nerve Integrity Monitoring® endotracheal tube during recurrent laryngeal nerve monitoring is of paramount importance. This article describes our experience with the GlideScope® and explains how it can facilitate the accurate placement of the Nerve Integrity Monitoring endotracheal tube.Methods:Endotracheal intubation with the Nerve Integrity Monitoring endotracheal tube was performed in 250 patients undergoing thyroidectomies using the GlideScope video laryngoscope. The correct positioning of the tube was determined according to impedance values of less than 5 kohm and an impedance imbalance of less than 1 kohm.Results:Successful intubation was achieved in all cases. The GlideScope aided the correct placement of the Nerve Integrity Monitoring endotracheal tube in the majority of the cases.Conclusion:The GlideScope provides an excellent means to ensure the correct positioning of the Nerve Integrity Monitoring tube. It allows both the surgeon and the anaesthesiologist to participate in the intubation process and confirm correct placement of the tube, whilst also allowing gentle intubation with improved visibility.

In the present study, 3 types of electrodes for recurrent laryngeal nerve (RLN) monitoring are compared: 1) intralaryngeal surface electrodes attached to a conventional endotracheal tube, 2) monopolar needle electrodes placed on the vocal cords by direct laryngoscopy, and 3) bipolar needle electrodes inserted intraoperatively through the cricothyroid ligament. Data were collected from stimulation of 21 RLNs in 16 patients undergoing thyroid surgery. The reliability in terms of distinct electromyographic (EMG) potentials following stimulation of the RLN was 100% with monopolar and bipolar needle electrodes and 76% with intralaryngeal surface electrodes. The mean (±SD) amplitudes of the EMG potentials were 1.61 ± 1.6 mV, 2.37 ± 1.8 mV, and 0.35 ± 0.4 mV for the monopolar endolaryngeal, bipolar transligament, and intralaryngeal surface electrodes, respectively. The advantages and disadvantages of each type of electrode are discussed.

Recurrent Laryngeal Nerve Monitoring

The authors herewith present a case of a non-conventional use of endotracheal tube-based IONM in a second-stage total thyroidectomy for metastatic papillary cancer incidentally detected after OPHL Type IIa + ary left for SCC. The use of the IONM in such case was effective avoiding the RLN accidental injury.
