We compared the effects of the Airway Scope(®) on haemodynamic responses during tracheal intubation with those of direct laryngoscopy in normotensive and hypertensive patients. The systolic blood pressure, diastolic blood pressures and heart rate were recorded: (a) before anaesthesia; (b) immediately before intubation; (c) at intubation; and (d) 1, 2, 3, 4 and 5 min after intubation. In normotensive patients, the increase in blood pressure and heart rate over time were significantly lower with the Airway Scope than with the Macintosh laryngoscope (p < 0.003). In hypertensive patients, however, there was no difference in the changes over time in any of these haemodynamic measures between the two devices (p > 0.05). We conclude that the Airway Scope attenuates haemodynamic responses to tracheal intubation in comparison with the laryngoscope in normotensive but not in hypertensive patients.

我们比较了气道内镜（®）和直接喉镜在正常血压和高血压患者气管插管期间对血流动力学反应的影响。记录收缩压、舒张压和心率：（a）麻醉前；（b）插管前即刻；（c）插管时；以及（d）插管后 1、2、3、4 和 5 分钟。在正常血压患者中，与 Macintosh 喉镜相比，气道内镜组的血压和心率随时间的增加明显较低（p < 0.003）。然而，在高血压患者中，这两种设备在这些血流动力学指标的任何变化方面均无差异（p > 0.05）。我们的结论是，与喉镜相比，气道内镜可减轻正常血压患者气管插管时的血流动力学反应，但在高血压患者中则无差异。您可以在 http://www.anaesthesiacorrespondence.com 上回复这篇文章。
