实用新型气管导管在困难气管插管中的临床应用研究

Study of the clinical application of the new-type endotracheal tube in difficult endotracheal intubation patients

目的研究实用新型气管导管*在困难气管插管中的临床应用价值;方法60例困难(或异常)气道患者,Ⅰ组(n=60):在麻醉诱导下,首先采用目前临床上使用的经口气管导管(传统气管导管)插管,在不用管芯情况下,分析其插管成功率;Ⅱ组:在Ⅰ组2次插管不成功者归为Ⅱ组,并换用实用新型气管导管插管,在不用管芯情况下分析其插管成功率;结果Ⅰ组1次插管成功率为11.67%,3次插管总成功率为18.33%;Ⅱ组1次插管成功率为71.43%,3次插管总成功率为93.88%,两组1次插管成功率和3次插管总成功率相比较,差异均有统计学意义(P<0.01);结论实用新型气管导管比传统气管导管有3大优点,①具有良好的可塑性;②无需辅用气管管芯插管;③能极易发挥软导引管的引导作用。说明实用新型气管导管比传统气管导管更加实用。

Objective To study and evaluate the clinical efficacy of new-type endotracheal tube in difficult endotracheal intubation patients. Methods A total of 60 patients with he abnormal airways were assigned into the control group（ named group I , n = 60 ） and the treated group （ named group Ⅱ , n = 49 ）. Group I ： on the induction of anesthesia, by the traditional endotrache- al tube by mouth,first, the successful intubating rate was analyzed,on the circumstances of no stylet; Group Ⅱ： the patients were used with new-type endotracheal tube after twice abortive intubating operation by traditional endotracheal tube in the total of 60 eases,and the successful rate was also analyzed,on the circumstances of no styler. Results （1）In the group I ：once and thrice successful intubating rate was 11.67% and 18. 33% respectively,In the group Ⅱ that was 71.43% and 93.88% respeetively;（2） Comparing of the efficacy data between the two groups showed that there was a good statistically significant difference（ P〈0. 01 ）. Conclution There were three points of forte, comparing with the traditional endotracheal tube during the intubating operation. The one is the good plasticity;The two is no styler during the intubating operation. And the third is the good guiding role of soft guidable catheter to bring into full play. It is more useful than that of the traditional endotracheal tube.
