改良光导气管导管在人体模型气管插管训练中的应用研究

目的探讨自制改良光导气管导管在人体模型体上进行气管插管训练的性能及应用前景。方法在普通气管插管导管的结构基础上,选用软硬适中的优质塑胶材料进行制作,将光导纤维植入导管体管壁,光导纤维输入端和输出端分别连接分光器和聚光器,导管外接口端固化自带光源发出光线,经分光器、光导纤维、聚光器照亮导管前端区域,使插管过程气道照明充足。按临床常用气管导管的规格、消毒标准制作出光导导管。抽取该院急诊科医师8人在人体模型身上进行气管插管训练,每人插管100次,记录人均一次插管成功率、人均每次插管时间,并与对照组比较。结果观察组一次插管成功87～96例,人均93.5例;成功率为87%～96%,人均93.65%;人均每次插管时间(11.59±0.38)s。对照组一次插管成功83～95例,人均89例;成功率为83%～95%,人均90.03%;人均每次插管时间(13.14±0.38)s。两组同性指标分别比较,差异均有统计学意义(P<0.01)。结论自制改良光导气管导管操作便捷、一次插管成功率高、耗时短,值得临床探讨。

Application study of improved light guided endotracheal catheter in the training of dummy tracheal intubation

Objective To explore the performance and its application prospect of self-made improved light guided endotracheal catheter in the training of dummy tracheal intubation.Method Based on the structure of ordinary tracheal intubation duct,using excellent plastic material of median hardness,the optical fiber were implanted into the duct′s wall,and the input and output outlet were connected with separately the spectroscope and the condense.The drive pipe external tap end solidification bringing photosource sent out the light and through spectroscope,the optical fiber,the condenser illuminated and illuminated front region of the duct and make the intubation process gas channel illumination to be sufficient.According to the clinical commonly used trachea drive pipe specification and the disinfection standard system,the light guide drive pipe was made.8 emergency doctors were chosen to carry out the trachea intubation training on dummy,each inserted a tube 100 times,average per person intubation success ratio,average per person each time intubation time were recorded and compared with the control group.Results First time succession were received in 87-96 example in the improved group,per capita 93.5 example;with a success rate of 87 to 96 per cent and per capita 93.65% each time,and per capita intubation time 11.59±0.38 s,as compared with 83-95 successful example,per capita 89 example;success rate of 83 to 95 per cent and per capita 90.03 % per capita per year,and 13.14±0.38 s intubation time in the control group,respectively.There existed statistical significant difference in homosexual indicators between the two groups(all P<0.01).Conclusion The self-made improvedlight guide trachea drive pipe has the advantage of operation convenience,high intubation success ratio,and less time consumption,and is worthy of the clinical discussion.
