帝视内窥镜辅助下经口气管插管的临床观察

Clinical Study of Orotracheal Endotracheal Intubation by Discopo Endoscope

目的：探讨帝视内窥镜用于全身麻醉患者经口气管插管的临床效果。方法：选择ASAⅠ~Ⅱ级,无困难气道患者40例,随机分为帝视内窥镜组（D组）和Macintosh直接喉镜组（M组）,每组各20例,常规麻醉诱导后分别使用帝视内窥镜和Macintosh喉镜进行气管插管,观察麻醉诱导前、麻醉诱导后插管前、插管后即刻及插管后2 min的SBP、DBP和HR。记录气管插管时间、1次成功率和相关并发症。结果：D组插管用时比M组更短（P〈0.05）,1次插管成功率高于M组,损伤事件及并发症少于M组（P〈0.05）,T2、T3血流动力学优于M组（P〈0.05）。结论：帝视内窥镜辅助下经口气管插管,安全有效,值得在临床上推广。

Objective：To study the effect of orotracheal endotracheal intubation by Discopo endoscope in patients scheduled for general anesthesia.Method：40 ASA Ⅰ-Ⅱ patients without difficult airway were randomly divided into Discopo endoscope group（D group） and Macintosh direct laryngoscope group（M group）,20 cases in each group.After a routine intravenous anesthetic induction,orotracheal endotracheal intubation was performed with Discopo endoscope or direct laryngoscope.The systolic blood pressure,diastolic blood pressure and heart rate of patients were recorded respectively at the time before anesthesia induction,before intubation,immediately after intubation and 2 minutes after intubation.Time required for intubation,successful intubation in once,traumatic and complications of intubation were also recorded.Result：Intubation time of D group was shorter than that of M group（P〈0.05）,successful intubation in once was higher than M group,traumatic and complications of intubation were less than M group（P〈0.05）,hemodynamics in T2 and T3 were better than M group（P〈0.05）.Conclusion：Application of Discopo endoscope for orotracheal endotrachealintubation is safe and effective,and should be promoted.
