Endotracheal intubation in rabbits can be challenging due to their unusual anatomy. Achieving a patent airway during anesthesia is critical for the avoidance of airway obstruction, prevention of gastric tympany, and to allow ventilatory support. Due to the difficulty of intubation, alternative methods such as the use of laryngeal mask airways or laryngeal tubes have been explored. However, these methods do not result in direct access to the trachea and thus may present a risk for development of complications. In addition, lack of direct intubation of the trachea can result in personnel exposure to waste anesthetic gases. Numerous methods for endotracheal intubation have been described, including blind placement, use of a fiberoptic laryngoscope or endoscope, and cricoid placement. Despite these numerous publications, many still struggle to achieve success. Here we provide a detailed description of an intubation technique that can be taught with minimal training with a short time to proficiency. Briefly, after administration of injectable anesthesia and proper positioning of the rabbit, a polypropylene catheter is placed into the trachea by direct visualization using a laryngoscope. The catheter is then used as a guide to direct the endotracheal tube into the trachea. This method allows for intubation without the need for expensive equipment and can be performed by a single individual without the need for an assistant. In conclusion, this technique can be easily taught and performed at very little cost in any clinical or research setting.
由于兔子独特的解剖结构，对其进行气管插管具有挑战性。在麻醉期间建立通畅的气道对于避免气道梗阻、预防胃鼓胀以及提供通气支持至关重要。由于插管困难，人们探索了诸如使用喉罩气道或喉管等替代方法。然而，这些方法无法直接进入气管，因此可能存在发生并发症的风险。此外，缺乏对气管的直接插管可能导致工作人员暴露于麻醉废气中。已经描述了许多气管插管方法，包括盲目置入、使用纤维喉镜或内镜以及环状软骨置入。尽管有众多相关出版物，但许多人在插管时仍难以成功。在此，我们详细描述一种插管技术，该技术只需极少的培训且能在短时间内熟练掌握。简而言之，在给予注射麻醉并对兔子进行正确定位后，使用喉镜通过直接观察将聚丙烯导管置入气管。然后将该导管用作引导，将气管导管导入气管。这种方法无需昂贵设备即可进行插管，并且一名操作人员无需助手就能完成。总之，在任何临床或研究环境中，这种技术都可以轻松传授且成本极低。
