TruviewTM EVO2光学喉镜与普通喉镜在呼吸衰竭抢救中的效果对比

摘要

目的：探讨 TruviewTM EVO2光学喉镜与普通喉镜在抢救呼吸衰竭患者中的临床效果。方法选取2013年2月至2014年3月需行紧急气管插管救治的呼吸衰竭患者64例，采用随机数表法将患者分为观察组（光学喉镜）和对照组（普通喉镜）各32例，比较两组患者的气道声门暴露 C/ L 分级、一次插管成功率、气管插管操作时间和术后并发症等。结果观察组气道声门暴露C/ L 分级为Ⅰ~Ⅱ级的患者例数多于对照组，而Ⅲ~Ⅳ级患者例数少于对照组，差异有统计学意义（P <0.05）；观察组一次插管成功率为93.75%，SpO2最低下降值范围分别为93.75%和（97.98±1.38）%，明显高于对照组的68.75%和（91.26±3.11）%，差异均有统计学意义（P <0.05）；两组气管插管操作时间比较，差异无统计学意义（P >0.05）；观察组并发症发生率为9.38%，明显低于对照组的34.37%，差异有统计学意义（P <0.05）。结论 TruviewTM EVO2光学喉镜具有插管成功率高、声门显露好的特点，适用于呼吸衰竭抢救。%Objective To investigate the clinical effect of TruviewTM EVO2 optic and common laryngoscope on the treatment of re-spiratory failure patients. Methods 64 cases of patients with respiratory failure ever treated with urgent trachea intubation from Feb 2013 to Mar 2014 were selected,and were equally divided into study group(optic laryngoscope)and control group(common laryngoscope)by ran-dom number table method. The C/ L classification of airway glottis exposure,one time success rate and operation time of tracheal intubation, and postoperative complications between the two groups were compared. Results Patients in the study group whose C/ L classification of air-way glottis exposure to be grade Ⅰ ~ Ⅱ were greater than those in the control group,but patients with grade Ⅲ ~ Ⅳ in the study group were fewer than those in the control group,and the differences between them were statistically significant(P < 0. 05). The one time success rate of tracheal intubation and the lowest range of SpO2 drop-off in the study group were 93. 75% and(97. 98 ± 1. 38)% ,respectively,which were also with significant differences when compared with those,68. 75% and(91. 26 ± 3. 11)% ,in the control group(P < 0. 05). There was significant difference between the incidence of complications in the study group and that in the control group(9. 38% vs 34. 37% ,P <0. 05),but no significant difference was found in the operation time of tracheal intubation between them(P > 0. 05). Conclusion The Tru-viewTM EVO2 optic laryngoscope has the characteristics of high success rate of intubation and better exposure of glottis,and is applicable to treatment of respiratory failure patients.
