Airtraq视频喉镜联合纤维支气管镜在困难气道插管中的效果评价

Evaluation of Airtraq video laryngoscope combined with fiberoptic bronchoscope in difficult airway intubation

摘要:

摘要：目的 分析评价Airtraq视频喉镜联合纤维支气管镜（FOB）在处理困难气道中的临床效果。方法 选择全身麻醉手术患者，术前经麻醉医师行Mallampati评估分级为Ⅲ或Ⅳ级，美国麻醉医师协会（ASA）分级Ⅰ或Ⅱ级，常规麻醉诱导后，先用普通喉镜行Cormack-Lehane评级，Ⅰ或Ⅱ级患者直接插管，将Ⅲ或Ⅳ级患者随机分为Airtraq视频喉镜联合FOB（A组）30例与Airtraq视频喉镜（B组）30例，然后实施经口气管插管，观察并记录两组患者插管次数、插管总时间、血流动力学变化及咽喉部损伤、咽喉痛情况。结果 A组患者插管时间和插管次数明显小于B组患者，差异均有统计学意义（P <0.05）；插管前后，两组收缩压（SBP）、心率（HR）和血氧饱和度（SpO2）比较，差异均无统计学意义（P >0.05）。结论 全身麻醉时应用Airtraq视频喉镜联合FOB，Cormack-Lehane评级Ⅲ级以上患者经口气管插管，具有全程可视、成功率高、插管时间短和减少气道及咽部损伤的优势。

Abstract: Objective To evaluate the clinical effect of disposable video laryngoscope (Airtraq) combined with fiberoptic bronchoscopy (FOB) in coping with difficult airway anesthesia. Methods The patients underwent Mallampati evaluation for anesthesiologists class III or IV, ASA grade I ~ II. Firstly, Cormack-Lehane rating patients directly through the ordinary laryngoscope intubation after induction of anesthesia. Class III or IV patients were randomly divided into Airtraq combined with FOB (A group, 30 cases) and Airtraq (group B, 30 cases). Then, the number of intubation, intubation time, hemodynamic changes, throat injury, and sore throat were recorded during the implementation of orotracheal intubation. Results The intubation time, intubation times in group A were less than those in group B, and the difference between group A and B was statistically significant (P < 0.05). Before and after intubation, mean arterial pressure was compared between group A and B, and the difference was not statistically significant (P > 0.05). Conclusion Compared with Airtraq, Airtraq combined with FOB shows more effective in clinical application for Cormack-Lehane rating grade III patients. The advantage of Airtraq combined with FOB inclding visible throughout, high success rate, short intubation time, and less airway and pharyngeal injury.
