Progressive respiratory failure due to massive endobronchial involvement causes death in some patients with bronchogenic carcinoma. The absence of satisfactory therapeutic modalities directed specifically at masses of endobronchial tumor has limited our ability to effectively palliate these patients. Electro-cautery is a technique which has the potential for removing large quantities of endobronchial tumor safely, painlessly , and without measurable blood loss. It is especially well suited to the patient requiring local palliation with immediate relief of airway obstruction and without a prolonged hospital stay. The report reviews: a) its use in an individual with tracheal obstruction; b) the effect of electrocautery current changes and probe type on canine trachea; and, c) the technical problems which must be considered in using endobronchial electrocautery. In the individual with tracheal obstruction, large amounts of tumor were cleared with excellent hemostasis. The canine trachea demonstrates that the amount and duration of current used are extremely important. Equipment available of gastrointestinal electrocautery can produce significant tracheal damage and must be used with great caution. Finally, fiberoptic bronchoscopes are not designed for electrocautery work, and care must be employed when performing such procedures through these instruments.
大量支气管内受累导致的进行性呼吸衰竭可致使部分支气管源性肺癌患者死亡。缺乏专门针对支气管内肿瘤块的有效治疗方式限制了我们有效缓解这些患者病情的能力。电烙术是一种能够安全、无痛且无明显失血地清除大量支气管内肿瘤的技术。它特别适用于需要局部缓解且能立即解除气道阻塞且无需长时间住院的患者。本报告回顾了：a) 其在一名气管阻塞患者中的应用；b) 电烙术电流变化及探头类型对犬类气管的影响；以及 c) 使用支气管内电烙术时必须考虑的技术问题。在气管阻塞患者中，大量肿瘤被清除且止血效果良好。犬类气管研究表明，所使用电流的量和持续时间极为重要。现有的胃肠电烙术设备可造成显著的气管损伤，必须谨慎使用。最后，纤维支气管镜并非为电烙术工作而设计，通过这些器械进行此类操作时必须格外小心。
