ABSTRACT. The recording electrodes including their precise location, their ability to record during movements that can be intense during a convulsive seizure, and their capability to record for several days without causing skin breakdown are an integral part of long-term EEG recording. Many of the facets of EEG technology have changed dramatically with the introduction of digital EEG. But the electrode and the electrode/skin interface have not had many dramatic changes. The technologist still looks for ways to ensure correct electrode placement, good recording capabilities, and a patient with healthy skin when the electrodes are removed. This Technical Tips features ideas and experiences from several technologists. These technologists express suggestions and opinions which are accepted in Technical Tips.

摘要记录电极包括它们的精确位置，它们在惊厥发作时可能剧烈的运动中记录的能力，以及它们在不引起皮肤破裂的情况下记录数天的能力，这些都是长期脑电图记录的组成部分。随着数字脑电图的引入，脑电图技术的许多方面都发生了巨大的变化。但电极和电极/皮肤界面并没有发生太大的变化。技术人员仍然在寻找方法来确保正确的电极放置，良好的记录能力，以及在电极移除时患者的皮肤健康。本技术提示介绍了几位技术专家的想法和经验。这些技术人员提出的建议和意见在技术提示中被接受。

ABSTRACT. Patients with hereditary neuropathy with liability to pressure palsy (HNPP) typically present with a mononeuropathy (particularly peroneal or ulnar palsy) or a brachial plexopathy. Careful electrodiagnostic testing has an important role in establishing the diagnosis of HNPP, differentiating this condition from other inherited or acquired neuropathies as well as obviating the need for unnecessary surgeries. We present a case of a patient who presented with a painless brachial plexopathy who was found to have multiple sites of segmental demyelination on nerve conduction studies, consistent with HNPP. We review the clinical and electrodiagnostic features of HNPP including the key electrodiagnostic findings to screen for this disorder.

摘要遗传性神经病变伴压迫性麻痹(HNPP)的患者通常表现为单神经病变(特别是腓骨或尺神经麻痹)或臂丛病。仔细的电诊断测试在确定HNPP的诊断，将其与其他遗传或获得性神经病变区分开来以及避免不必要的手术需要方面具有重要作用。我们报告了一例无痛性臂丛病患者，在神经传导研究中发现有多处节段性脱髓鞘，与HNPP一致。我们回顾了HNPP的临床和电诊断特征，包括筛选这种疾病的关键电诊断结果。

ABSTRACT. Motor evoked potentials (MEPs) elicited by both direct cortical stimulation (DCS) and transcranial electrical stimulation are used during brain tumor resection. Parallel use of direct cortical stimulation motor evoked potentials (DCS-MEPs) and transcranial electrical stimulation motor evoked potentials (TCeMEPs) has been practiced during brain tumor resection. We report that DCS-MEPs elicited by direct subdural grid stimulation, but not TCeMEPs, detected brain ischemia during brain tumor resection. Following resection of a brainstem high-grade glioma in a 21-year-old, the threshold of cortical motor-evoked-potentials (cMEPs) increased from 13 mA to 20 mA while amplitudes decreased. No changes were noted in transcranial motor evoked potentials (TCMEPs), somatosensory evoked potentials (SSEPs), auditory evoked potentials (AEPs), anesthetics, or hemodynamic parameters. Our case showed the loss of cMEPs and SSEPs, but not TCeMEPs. Permanent loss of DCS-MEPs and SSEPs was correlated with permanent left hemiplegia in our patient even when appropriate action was taken. Parallel use of DCS- and TCeMEPs with SSEPs improves sensitivity of intraoperative detection of motor impairment. DCS may be superior to TCeMEPs during brain tumor resection.

摘要在脑肿瘤切除术中使用直接皮层刺激(DCS)和经颅电刺激引起的运动诱发电位(MEPs)。在脑肿瘤切除术中，平行使用直接皮层刺激运动诱发电位(DCS-MEPs)和经颅电刺激运动诱发电位(TCeMEPs)已被实践。我们报告了直接硬膜下网格刺激引起的DCS-MEPs，而不是TCeMEPs，检测脑肿瘤切除术期间的脑缺血。21岁脑干高级胶质瘤切除后，皮质运动诱发电位(cMEPs)阈值从13 mA增加到20 mA，而振幅下降。经颅运动诱发电位(TCMEPs)、体感诱发电位(ssep)、听觉诱发电位(AEPs)、麻醉剂或血流动力学参数均无变化。我们的病例显示cmep和ssep丢失，但没有tcemep。即使采取了适当的措施，我们的患者的DCS-MEPs和ssep的永久性丧失与永久性左偏瘫相关。DCS-和TCeMEPs与ssep同时使用可提高术中检测运动损伤的灵敏度。在脑肿瘤切除术中，DCS可能优于TCeMEPs。

The secure and efficient affixation of EEG electrodes is an integral part of performing neurotelemetry; however there are currently no recommendations for the ideal method of affixing the electrodes that has evidence-based support. The purpose of this study was to find and determine the best hook up method based on the required hook up time and number of repairs. One hundred neurotelemetry patients were randomly assigned to one of the following four electrode application methods: collodion-Ten20, collodion-Elefix, Hypafix-Ten20, or Hypafix-Elefix. The collodion-Ten20 method had the longest average hook up time (53.7 min) and the lowest percentage of patients who needed repairs (24%); the Hypafix-Ten20 method had the shortest average hook up time (42.1 min); and the Hypafix-Elefix had the highest percentage of patients who needed repairs (86.4%). Based on these results, the study led to the recommendations that collodion-Ten20 be used for neurotelemetry studies lasting 24 hours or more and that Hypafix is more suitable for routine EEG studies.

安全高效的脑电电极连接是进行神经遥测的重要组成部分;然而，目前尚无证据支持的理想电极固定方法的建议。本研究的目的是根据所需的钩接时间和修复次数，找到并确定最佳的钩接方法。100名神经遥测患者被随机分配到以下四种电极应用方法之一:collodion-Ten20、collodion-Elefix、Hypafix-Ten20或Hypafix-Elefix。collodion-Ten20法平均连接时间最长(53.7 min)，需要修复的患者比例最低(24%);Hypafix-Ten20法平均连接时间最短(42.1 min);而Hypafix-Elefix的患者需要修复的比例最高(86.4%)。基于这些结果，该研究建议将collodion-Ten20用于持续24小时或更长时间的神经遥测研究，而Hypafix更适合用于常规脑电图研究。

ABSTRACT. The use of somatosensory evoked potentials (SSEPs) to monitor upper extremity nerves during surgery is becoming more accepted as a valid and useful technique to minimize intraoperative nerve injuries. We present a case illustrating the benefit of utilizing both SSEPs and transcranial electrical motor evoked potentials (TCeMEPs) for preventing position-related injury during surgery. The patient was a 43-year-old male with a history of neck pain, along with numbness and tingling of the upper extremities. While the patient was being draped, upper extremity SSEPs diminished significantly. TCeMEP responses in the hands (abductor pollicus brevis-abductor digiti minimi; APB-ADM) vanished shortly after that, followed by the biceps and left deltoid. The surgeons were notified, and the tape on the shoulders was loosened. No improvements were noted in SSEPs nor TCeMEPs due to this intervention, so all tape was removed and the patient's arms were allowed to rest naturally upon the arm boards. Upper extremity TCeMEP responses could then be elicited and SSEPs improved shortly afterward. Surgery was completed with the arms on the arm boards. All signals remained stable for the remaining three hours of the procedure. At two months follow-up, the patient was well with total pain relief and normal upper extremity function when neurological examination was performed. This report demonstrates a case in which intraoperative neurophysiological monitoring was useful in identifying and reversing impending nerve injury during cervical spine surgery. Significant changes were seen in SSEPs as well as TCeMEPs, so we recommend that TCeMEP monitoring be considered as an adjunct to SSEPs for prevention of injury to the brachial plexus.

摘要术中使用体感诱发电位(ssep)监测上肢神经作为一种有效和有用的技术来减少术中神经损伤，越来越被接受。我们提出了一个案例，说明了在手术中使用ssep和经颅电运动诱发电位(TCeMEPs)预防体位相关损伤的好处。患者为43岁男性，有颈部疼痛史，上肢麻木和刺痛。当患者被悬吊时，上肢ssep显著降低。手部TCeMEP反应(短拇外展肌-小指外展肌;APB-ADM消失后不久，其次是二头肌和左三角肌。通知了外科医生，肩膀上的胶带被解开了。由于这种干预，没有发现ssep和TCeMEPs的改善，因此所有胶带都被拆除，患者的手臂被允许自然地放在手臂板上。随后，上肢TCeMEP反应可被激发，ssep随即得到改善。手术完成时，手臂固定在手臂板上。在接下来的三个小时里，所有的信号都保持稳定。随访2个月，行神经学检查，患者疼痛完全缓解，上肢功能正常。本报告展示了一例术中神经生理监测在识别和逆转颈椎手术中即将发生的神经损伤方面是有用的。ssep和TCeMEP均有显著变化，因此我们建议将TCeMEP监测作为ssep的辅助手段，以预防臂丛损伤。
