自制鼻咽通气导管

目的：研制一种新型鼻咽通气导管，解决患者在麻醉过程中舌后坠导致上呼吸道不通畅问题。方法：利用套囊已破损的各型号乳胶弹簧气管导管，剥掉套囊，根据患者需要长度不同，剪去导管尾端多余部分，然后装上导管接头。结果：观察50例麻醉过程中发生舌后坠患者，置入该通气导管后，鼾声消失，呼吸道通畅。结论：新型鼻咽通气导管改制容易，符合临床需要。

Homemade Ventilation Catheter of Nasopharyngeal

Objective To design a new type of nasopharyngeal airway tube,which can resolve the upper respiratory tract obstruction due to general anesthesia.Methods All types of used flex endotracheal tube were collected.Take off the cuff outside of the tube wall and cut them into different lengths.Then,the connectors were reinstalled to the prepared tubes.Results With the designed nsopharyngeal airway tubes inserted,50 patients having complicated glossocoma in general anesthesia no longer snored and they could breathe freely.Conclusion The new type of nsopharyngeal airway tube is easy to produce and adapts well to clinical work.
