In over 100 chronic obstructive pulmonary disease patients, continuous oxygen therapy has been provided for up to 4 years using Micro-Trach percutaneous transtracheal catheters less than 2.0 mm in diameter. Successful rehabilitation has been achieved. Advances in materials, insertion technique, and protocols have simplified patient management. Complications occasionally encountered are bleeding, infection, subcutaneous emphysema, increased mucus production, and catheter failure or displacement. Long-term delivery of supplemental oxygen directly into the tracheobronchial tree eliminates the oxygen loss through the oral and nasal orifices that occurs when a nasal cannula is used. This closed system permits maintenance of therapeutic arterial blood levels with improved efficiency, greater comfort, and increased activity. The elimination of nasal irritation and cosmetic objections caused by nasal cannulas increases patient compliance, resulting in uninterrupted 24-hour-a-day oxygen use as indicated. The technique of inserting a transtracheal catheter and postinsertion management are discussed in detail.
在100多名慢性阻塞性肺疾病患者中，使用直径小于2.0毫米的微型气管经皮气管导管进行了长达4年的持续氧疗。已实现成功康复。材料、插入技术和方案的进步简化了患者管理。偶尔遇到的并发症有出血、感染、皮下气肿、黏液分泌增加以及导管故障或移位。将补充氧气长期直接输送到气管支气管树中，消除了使用鼻导管时通过口腔和鼻孔发生的氧气损失。这种封闭系统能够以更高的效率、更大的舒适度和增加的活动量维持治疗性动脉血水平。消除了鼻导管引起的鼻刺激和美容方面的问题，提高了患者的依从性，从而可按指示每天24小时不间断地使用氧气。详细讨论了插入经气管导管的技术和插入后的管理。
