Objective To investigate the efficacies of viedo laryngoscope and direct laryngo-scope for in ICU patients with non-airway difficulties.Methods Sixty ICU patients with non-air-way difficulties were divided into viedo laryngoscope group(n=34)and direct laryngoscope group (n= 26).Tracheal intubation was performed after intravenous anesthesia.The success rate of first-attempt intubation,intubation time(from insertion of laryngoscope into the mouth to extrac-tion of the endotracheal guidewire),incidence of complications,and serum levels of cortisol(Cor) and interleukin-8(IL-8)were compared between the two groups.Results Compared with direct laryngoscope group,the success rate of first-attempt intubation increased,and the intubation time,incidence of complications and serum levels of Cor and IL-8 decreased in viedo laryngoscope group(P < 0.05).Conclusion Compared with direct laryngoscope,viedo laryngoscope can in-crease intubation success rate,decrease complications and relieve stress and inflammatory re-sponse in ICU patients with non-airway difficulties.%目的：探讨可视喉镜和普通喉镜在 ICU 非气道困难患者气管插管中的应用效果。方法选择60例 ICU非气道困难患者，根据使用喉镜的不同将60例患者分为可视喉镜组34例和普通喉镜组26例。患者静脉全身麻醉后行气管插管，比较2组一次插管成功率、插管时间（喉镜进入口腔至拔出气管内导丝后时间）、并发症发生率及血清皮质醇（Cor）、白介素-8（IL-8）水平。结果可视喉镜组的一次插管成功率显著高于普通喉镜组，插管时间和并发症发生率显著低于普通喉镜组（均 P ＜0．05）。可视喉镜组的血清皮质醇（Cor）和 IL-8水平显著低于普通喉镜组（P ＜0．05）。结论可视喉镜较普通喉镜在 ICU 非气道困难患者气管插管中应用可提高成功率，降低并发症，减轻应激和炎症反应。
