Abstract

Somatosensory evoked potentials (SSEPs) are used in spinal surgeries to monitor the functional integrity of dorsal column medial lemniscal pathways. Changes to waveform amplitudes can be due to surgical manipulation, in addition to many outside factors. We describe a posterior lumbar decompression/fusion case in which lower extremity (LE) SSEPs were performed and deteriorated bilaterally. These changes were found to be related to a safety strap traversing the posterior thighs that was excessively tight, causing neurological dysfunction. After loosening the strap, SSEP amplitudes and latencies returned to baseline parameters. This observation demonstrates the importance of careful patient positioning and application of external restraints. Numerous reports have described upper extremity (UE) positioning issues, but there are few that detail LE positioning issues. Intraoperative neuromonitoring (IONM) clinicians should be aware of various potential effects of improper positioning on IONM data and be vigilant in recognizing these instances.

术中安全带过紧导致下肢SSEP缺失1例。

躯体感觉诱发电位（ssep）在脊柱外科手术中用于监测背柱内侧运动通路的功能完整性。波形振幅的变化可能是由于手术操作，以及许多外部因素。我们描述了一个后路腰椎减压/融合病例，其中下肢（LE） ssep进行了双侧恶化。这些变化被发现与横穿大腿后部的安全带过紧有关，导致神经功能障碍。松开腕带后，SSEP振幅和潜伏期恢复到基线参数。这一观察结果表明，仔细的病人定位和外部约束的应用的重要性。许多报道描述了上肢（UE）定位问题，但很少有详细的LE定位问题。术中神经监测（IONM）临床医生应意识到定位不当对IONM数据的各种潜在影响，并在识别这些情况时保持警惕。

期刊介绍： The Neurodiagnostic Journal is the official journal of ASET - The Neurodiagnostic Society. It serves as an educational resource for Neurodiagnostic professionals, a vehicle for introducing new techniques and innovative technologies in the field, patient safety and advocacy, and an avenue for sharing best practices within the Neurodiagnostic Technology profession. The journal features original articles about electroencephalography (EEG), evoked potentials (EP), intraoperative neuromonitoring (IONM), nerve conduction (NC), polysomnography (PSG), autonomic testing, and long-term monitoring (LTM) in the intensive care (ICU) and epilepsy monitoring units (EMU). Subject matter also includes education, training, lab management, legislative and licensure needs, guidelines for standards of care, and the impact of our profession in healthcare and society. The journal seeks to foster ideas, commentary, and news from technologists, physicians, clinicians, managers/leaders, and professional organizations, and to introduce trends and the latest developments in the field of neurodiagnostics. Media reviews, case studies, ASET Annual Conference proceedings, review articles, and quizzes for ASET-CEUs are also published in The Neurodiagnostic Journal.
