侧孔型鼻咽通气道的研制及应用

Design and Application of Nasopharyngeal Airway with Side Holes

目的:研制一种可减轻对鼻腔黏膜损伤的侧孔型鼻咽通气道并应用于临床。方法:在传统鼻咽通气道结构的基础上进行了改进,在导气管上均匀开有6～8个直径为导气管外径1/3大小的圆形侧孔,将咽端的端口设计为45°斜面的斜口结构,其咽端斜口朝向弧形结构的导气管所在弧面的左侧或右侧。观察侧孔型鼻咽通气道在临床中的应用效果。结果:采用侧孔型鼻咽通气道的病例全部顺利进行通气,置入顺利,通气效果良好,无明显并发症。结论:侧孔型鼻咽通气道在临床应用中安全、可靠、效果好,并发症少。

Objective To design a nasopharyngeal airway with side holes to reduce nasal cavity mucous membrane injury and apply it clinically. Methods The structure of nasopharyngeal airway was refined on the basis of the traditional one, opening 6-8 round side holes on the airway tube whose outside diameter was two times as the holes, keeping the port of pharyngeal side to oblique structure of 45-degree bevel and the inclined hole was towards the left or right side of arc of the airway tube. The effect of nasopharyngeal airway with side holes was evaluated for the clinical application. Results The courses of operation were smooth. All cases with nasopharyngeal airway with side holes had a good ventilation effect and none had signification complications. Conclusion Applying the nasopharyngeal airway with side holes clinically is safe, reliable, effective and with few complications.
