自制气管插管在小尾寒羊全身麻醉中的应用

小尾寒羊脊柱变化趋势与人的有很多相似之处，随着外科模型的发展，成为研究脊柱发病原因与治疗方法的重要实验用动物模型。在羊脊柱外科实验中，对羊进行气管插管可以保证呼吸道畅通、辅助呼吸、便于监测调控、减少术中牵拉对气管的损伤。羊气管的长度较猪长，而且其嘴开口度有限，插管难度相对较大,而市售气管插管长度又不够。笔者经多次尝试后，自制了气管插管。应用自制的气管插管及工具，进行插管时，应熟悉羊的呼吸系统生理解剖结构，采用正确的气管插管方法。笔者对文献进行检索，发现相关文献较少，因之对小尾寒羊麻醉、对羊仰卧位麻醉后气管插管、术中监测及术后护理等方面进行了总结，为实验人员提供参考。

Application of Self-made Endotracheal Tube in Anesthetized Small Tail Han Sheep

Small Tail Han sheep have become an importmant experimental animal applying to etiology and treatment of related spinal column diseases because their changes similar with human. The trachea cannula could ensure the airway smooth, auxiliary breathing, easy to monitor and reduce intraoperative traction damage to the trachea in the sheep spinal surgery experiment.But It is more difficult for trachea cannula of sheep since its longer trachea and limited mouth opening.Because endotracheal tube in the market is relatively shorter, autheros succeed in making endotracheal tube for trachea cannula after many attempts. It is key to familiar with the anatomical structure of the sheep respiratory system as well as correct operations should be applied. Therefore in this article Small Tail Han sheep anesthesia, tracheal intubation, intraoperative monitoring and postoperative care were summarized in order to provide reference for the experimental staff.
