目的：比较应用视可尼喉镜与普通喉镜对无困难气道患者气管插管时的心血管反应。方法：选择80例ASAⅠ～Ⅱ级全身麻醉患者，包括非高血压组40例（ N组）和高血压组40例（ H组），根据插管器械不同两组又随机分成普通喉镜组（L组）和视可尼喉镜组（S组），比较四组患者麻醉诱导前后血流动力学改变，插管时间及气管插管并发症。结果：视可尼喉镜气管插管时和插管后的各项血流动力学指标均显著低于普通喉镜组（P＜0．05），普通喉镜组和视可尼喉镜组插管时间及插管并发症差异均有统计学意义（P ＜0．05）。结论：对于全麻气管插管患者，采用视可尼光斑法行气管插管可减少患者的血流动力学反应，缩短气管插管的时间，减少气管插管的并发症。%Objective:To compare the hemodynamic response to orotra-cheal intubation using Shikani laryngoscope and direct laryngoscope in pa-tients without difficult airway.Methods: Eighty patients of ASA Ⅰ -Ⅱunder general anesthesia were initially allocated to non-hypertensive group ( group N; n =40 ) and hypertension group ( group H;n =40 ) , and sub-grouped into direct laryngoscopy ( group L ) and Shikani laryngoscopy ( group S) on the device used basis.The four groups were compared perti-nent to hemodynamic changes before and after anesthesia induction ,intu-bation time and complications in endotracheal intubation .Results: Lower hemodynamic indicators during and after intubation were seen in group S as compared with group L(P<0.05),and group S and group L were sta-tistically different regarding the intubation time and complications from in-tubation(P<0.05).Conclusion: Shikani laryngoscopy with “spot meth-od” may reduce the hemodynamic response to endotracheal intubation and the intubation time as well as complications from intubation for patient un-der general endotracheal anesthesia.
