Abstract: 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.

Key words: Small Tail Han sheep, endotracheal tube, anesthesia
