摘要
目的:观察McCoy喉镜协助光导纤维支气管镜(FOB)经口气管插管在全身麻醉诱导后困难气管插管中应用的临床效果。方法:将40例ASAⅠ或Ⅱ级全身麻醉诱导后McCoy喉镜窥喉不能看见声门任何部分的患者随机均分为两组(n=20):McCoy喉镜协助FOB经鼻插管组(对照组)和McCoy喉镜协助FOB经口插管组(研究组)。观察并记录两组麻醉诱导前(T0,基础值)、首次插管前(T1)、插管成功即刻(T2)和插管成功后1min(T3)的收缩压(SBP)、舒张压(DBP)和心率(HR)。统计两种方法插管一次成功率、多次成功率、插管耗时和插管并发症。结果:T0、T1、T2、T3等时点两组间SBP、DBP和HR经比较差异无统计学意义(P>0.05);气管插管一次成功率、插管耗时和插管并发症两组间经比较差异均无统计学意义(P>0.05),多次成功率均为100%。结论:McCoy喉镜协助FOB经口气管插管成功率高,耗时短,可作为全麻诱导后困难插管方法之一。
Objective To observe the clinical effect of the application of McCoy laryngoscope combined with fiberoptic bronchoscope in difficult orotracheal intubation after induction of general anaesthesia. Methods Forty patients unable to expose glottis after induction of general anaesthesia with McCoy laryngoscope were randomly divided into two groups with 20 cases of each： nasotracheal intubation with McCoy laryngoscope combined with fiberoptic bronchoscope group （Group F） and orotracheal intubation with McCoy laryngoscope combined with fiberoptic bronchoscope group （Group C）. Systolic blood pressure （SBP）, diastolic blood pressure （DBP）, and heart rate （HR） were observed and recorded before anesthesia induction （To）, before intubation for the first time （TI）, instance after intubation （T2）, and 1 rain after intubation （T3）. The successful rate of one- time intubation, the total successful rate of multi-time intubation, the duration time of intubation, and complications were recored. Results There was no significant difference of SBP, DBP, and HR at the time of To, T, T2, T3 between the two groups （P 〉 0.05）. There was also no significant difference of the successful rate of one-time intubation, the duration time of intubation, and complications of intubation between the two groups （P 〉 0.05）. All the patients were successfully intubated. Conclusion Orotracheal intubation with McCoy laryngoscope combined with fiberoptic bronchoscope can be regarded as one of the preferred means in difficult intubation after general anesthesia induction for its high successful rate and short time.
