内窥镜在大鼠气管插管中的应用

Endoscropic assist in rat orotracheal intubation

目的探讨内窥镜辅助大鼠气管插管方法。方法将40只大鼠随机分成内镜组和直视组两组,比较插管操作时间、插管总完成时间、插管次数、插管一次成功率、呕吐反射次数、窒息次数和拔管后24存活率。结果内镜组的插管操作时间、插管次数、一次插管成功率、呕吐反射次数、窒息次数均优于经经口明视组(P<0.05),插管总完成时间、拔管后24存活率比较差异无统计学意义(P>0.05)。结论采用内窥镜辅助插管法优于传统的经口指视插管法,值得推广。

Objective To investigate endoscropic assist in rat orotracheal intubation.Methods 40 rats were randomly divided into two groups.The procedure time,total time,intubation frequency,the success rate of the first intubation and the survival rate in 24 h were compared between the conventional group and the endoscropic group.Results The total time in two groups were nearly the same.But the procedure time and frequency of intubation were significantly less in the endoscropic group than those in the conventional group.The success rate of the first intubation in the endoscropic group was obviously higher than that of the conventional group.There was no obviously difference between the survival rate after extubation in 24 h between groups.Conclusion Endoscropic assist is superior to the conventional method and worth promoting.
