可视喉镜在双腔支气管导管插管中的应用

Application of Visual Laryngoscope in Double- lumen Endobronchial Intubation

目的探讨可视喉镜在双腔支气管导管插管中的应用效果。方法将110例双腔支气管导管插管全麻下行择期手术的患者随机分为观察组(n=55)和对照组(n=55),对照组采用普通喉镜插管,观察组应用可视喉镜插管,比较两组患者的插管时间、插管成功率、插管损伤、血流动力学变化等。结果观察组患者的气管导管定位时间及插管时间均显著短于对照组(P<0.05),首次及总插管成功率均显著高于对照组,插管损伤发生率明显低于对照组(P<0.05);对照组插管中及插管后的Sp O2值均显著低于麻醉前和观察组(P<0.05)。结论可视喉镜应用于双腔气管导管插管,具有插管成功率高、插管时间短、插管损伤小、血流动力学影响小的优点,是行双腔气管导管插管的理想工具。

Objective To study the application effect of visual laryngoscope in a double -lumen endobronchial tube intubation. Methods 110 patients of double - lumen endobronchial tube intubation to undergo elective surgery under general anesthesia were randomly divided into observation group （n = 55 ） and control group（ n = 55 ）. Ordinary laryngoscope was ap- plied in the control group, and visual laryngoscope in observation group. Intubation time, success rate of intubation, intuba- tion injury, hemodynamie changes were compared in two groups. Results The positioning time and intubation time in the observation group were significantly shorter than the control group （ P 〈 0. 05 ）. For the first time and total intubation success rate was significantly higher than the control group and intubation injury rate was lower than the control group （ P 〈 0. 05 ）. SPO2 levels during and after intubation in the control group were significantly lower than those before anesthesia and in the ob- servation group （ P 〈 0. 05 ）. Conclusion The application of visual laryngoscopy in double - lumen endotracheal intubation has advantageous for its high success rate, short intubation tittle, small incubation damage, small impact of hemodynamic It is an ideal tool for double -lumen endotracheal intubation.
