To compare the hemodynamic responses to orotracheal intubation with Laryngeal Mask Airway CTrach™ and Laryngoscope under general anesthesia.
60 adult patients, scheduled for the elective gynecologic surgery under general anesthesia requiring the orotracheal intubation, were randomly allocated to either the CTrach (C) group or the Laryngoscope (D) group. After a standard intravenous anesthetic induction, the orotracheal intubation was performed. Noninvasive blood pressures and heart rates were recorded before (the baseline values) and after anesthesia induction(the postinduction values), at intubation and every minute for the first 3 minutes after intubation.
The mean intubation time was longer in the C group than in the D group. The tracheal intubations caused significant increases in blood pressures and heart rates in the two groups compared to their postinduction values. In the D group, HR at intubation and after intubation were significantly higher Compared to the baseline values. In the C group, BP and HR at intubation and after intubation were not significantly different from the baseline values. BP and HR at intubation and after intubation were significantly higher in the D group than in the C group.
The CTrach had advantage of attenuating the hemodynamic responses to the orotracheal intubation compared to the laryngoscope.
比较全身麻醉下使用喉罩气道CTrach™和喉镜经口气管插管时的血流动力学反应。
60例计划在全身麻醉下行择期妇科手术且需要经口气管插管的成年患者，随机分为CTrach（C）组或喉镜（D）组。在标准静脉麻醉诱导后，进行经口气管插管。在麻醉诱导前（基线值）、麻醉诱导后（诱导后值）、插管时以及插管后前3分钟每分钟记录无创血压和心率。
C组的平均插管时间比D组长。与诱导后值相比，两组气管插管均导致血压和心率显著升高。在D组，插管时和插管后的心率与基线值相比显著更高。在C组，插管时和插管后的血压及心率与基线值无显著差异。D组插管时和插管后的血压及心率显著高于C组。
与喉镜相比，CTrach在减轻经口气管插管的血流动力学反应方面具有优势。
