自制麦克风光棒联合导管芯在困难气管插管中的应用

Application of self-made microphone light wand in patients with difficult airway

目的观察自制麦克风光棒联合导管芯在困难气管插管中的临床应用效果。方法42例已预料困难气道行气管插管全麻患者，按随机数字表法分为自制麦克风光棒联合导管芯气管插管组（Ⅰ组）和普通喉镜气管插管组（Ⅱ组），每组21例。记录两组患者的一次插管成功率、插管时间，观察气管插管并发症如插管即刻的血流动力学改变、口咽黏膜出血以及术后6h的咽喉疼痛和声音嘶哑情况。结果与Ⅱ组比较，Ⅰ组的一次插管成功率（90．5％VS57．1％）明显增高（P〈0．05），插管时间（86±19）s vs（276±36）s明显缩短（P〈0．05）；Ⅰ组的插管即刻血流动力学改变、口咽黏膜出血、术后6h咽喉痛和声音嘶哑明显少于Ⅱ组（P〈0．05）。结论自制麦克风光棒联合导管芯对困难气管插管是一种比较安全、有效的方法，有一定临床应用价值。

Objective To study the clinical efficacy of self-made microphone light wand in patients with difficult airway. Methods 42 patients with difficult airway scheduled for tracheal intubation were randomly divided into two groups, 21 cases in each group. Self-made microphone light wand was used in group I , while laryngoscope was used in group II. The first successful rate of intubation and the time of intubation were recorded. Hemodynamic change and the complications of intubation were observed in all patients. Results There were no difference in age, sex and weight between two groups （P〉0.05）. The first successful rate of intubation in group I was significantly higher than that in group II （90.5% vs 57.1%, P〈0.05）, the time of intubation decreased significantly in group I [（86±19） s vs （276±36） s, P〈0.05]. Compared with group II , the complications of intubation such as hemodynamic change, oropharyngeal mucosal hemorrhage, sore throat and hoarseness in group I were better（P〈0.05）. Conclusions Self-made microphone light wand is relatively safe, effective and promising in patients with difficult airway.
