摘要
目的:分析并探讨帝视内窥镜在双腔支气管插管时的BIS(脑电双频谱指数)的变化及在全麻诱导插管过程中对心血管的反应。方法:选择择期全麻胸科手术患者40例,应用双腔支气管导管插管。采用随机数字表法,将其分成2组:帝视内窥镜(Ⅰ组)和Macintosh弯喉镜组(Ⅱ组),每组20例。记录各组麻醉诱导前(T1),诱导后3 min(T2),帝视内窥镜和Macintosh弯喉镜气管插管后即刻(T3)、1 min(T4)、5 min(T5)时的MAP(平均动脉压)、HR(心率)、BIS值的变化。结果:Ⅰ组置入帝视内窥镜前后T3、T4时MAP、HR、BIS值组内比较无显著性差异(P>0.05);Ⅱ组Macintosh弯喉镜插管前后T3、T4时MAP、HR、BIS值较T2时均升高,差异有统计学意义(P<0.05)。两组患者的BIS数值在麻醉诱导后较麻醉前明显减小(P>0.05),两组之间的BIS数值对比,Macintosh弯喉镜组在插管时与插管后1 min时均明显高于帝视内窥镜组(P<0.05),具有统计学意义。结论:帝视内窥镜在双腔气管插管时对患者心血管系统和BIS数值变化影响较小。
Objective: To analyze and discuss the changes of BIS during the double lumen intubation and the response to the cardiovascular response during the induction of general anesthesia. Methods: Select 40 patients undergoing thoracic operation, Double lumen tube intubation. Using the random number table method, it is divided into 2 groups : Disposcope (Group I)and Macintosh group, 20 cases of each group. Recorded before anesthesia induction (T1), after induction 3min ( T2 ), discope and Macintosh after tracheal intubation Immediate (T3) ,1 min ( T4 ) ,5 min (TS) ,BP,MAP, HR,the change of BIS value. Results: In Group I , with placement of discope before and after T3,T4, MAP, HR, there was no significant difference in B1S values( P 〉 0. 05 ). In Group Ⅱ ,before and after the general curved Macintosh intubation T3 ,T4,MAP,HR, the BIS value was higher than that of T2, The difference was statistically significant( P 〈 0.05 ). The BIS values of the two groups were significantly decreased after anesthesia induction ( P 〉 0.05 ). With BIS numerical comparison between the two groups, in the patients of Macintosh laryngoscope group in intubation and 1 min after intubation was significantly higher than that in Discope Group (P 〈 0.05 ), with statistical significance. Conclusions: In the double lumen endotracheal intubation, the influence of the changes of the cardiovascular system and the BIS value was smaller.
