The most commonly used recording-side method in intraoperative neural monitoring (IONM) detects the stimulus with the endotracheal tube surface (ETS) electrodes placed in the endotracheal tube during thyroidectomy. The thyroid cartilage needle (TCN) electrode method is an alternative recording-side system in IONM. This study compared two recording-side techniques in IONM.
Data were retrospectively analyzed from 885 patients who underwent thyroidectomy between January 2012 and December 2020, with 110 ETS and 775 TCN electrodes. Patients' demographics, diagnosis, surgery type, and amplitudes of all stimulation steps were compared. Costs per patient were calculated.
No significant differences were found in the demographic data between the two groups. All amplitudes were higher in the IONM system where TCN electrodes were used than that with ETS electrodes (all stimulation steps p < 0.001, except left-V2 p = 0.007). Further, TCN electrodes were 20 times cheaper than the ETS electrodes.
TCN electrodes are an inexpensive and efficient alternative to ETS electrodes in IONM.
术中神经监测（IONM）中最常用的记录侧方法是使用放置在气管内管中的气管内管表面（ETS）电极检测刺激，在甲状腺切除术期间。甲状腺软骨针（TCN）电极方法是 IONM 中的替代记录侧系统。本研究比较了 IONM 中的两种记录侧技术。
回顾性分析了 2012 年 1 月至 2020 年 12 月期间接受甲状腺切除术的 885 例患者的数据，其中 110 例 ETS 和 775 例 TCN 电极。比较了患者的人口统计学数据、诊断、手术类型以及所有刺激步骤的振幅。计算了每位患者的成本。
两组患者的人口统计学数据无显著差异。在使用 TCN 电极的 IONM 系统中，所有振幅均高于使用 ETS 电极的系统（所有刺激步骤 p < 0.001，除左侧 V2 p = 0.007）。此外，TCN 电极比 ETS 电极便宜 20 倍。
在 IONM 中，TCN 电极是 ETS 电极的一种经济高效的替代方法。
