An Innovative Approach to Orotracheal Intubations: The Alexandrou Angle of Intubation Position

Visualization of the vocal cords is paramount during orotracheal intubations. We employed a novel patient position in this derivation study. The Alexandrou Angle of Intubation (AAI) position is defined as a 20°–30° incline where the supine patient's head is elevated in relation to the body and legs. Our study participants were blinded to the goals of the research as well as our novel technique. Using intubation manikins, our participants ranked their preference for visualizing the vocal cords between the Flat, Trendelenburg, and AAI positions. A majority (58.8%) of our study participants preferred the AAI for visualizing the vocal cords over the other two positions. Future studies will reveal whether AAI will play a significant role in emergent airway management.

在经口气管插管过程中，声带的可视化至关重要。在这项衍生研究中，我们采用了一种新的患者体位。亚历山德鲁插管角度（AAI）体位定义为仰卧患者的头部相对于身体和腿部抬高20° - 30°的倾斜角度。我们的研究参与者对研究目的以及我们的新技术不知情。使用插管模拟人，参与者对平卧位、头低脚高位和AAI体位在声带可视化方面的偏好进行了排序。我们研究的大多数参与者（58.8%）在声带可视化方面更喜欢AAI体位，而不是其他两种体位。未来的研究将揭示AAI是否会在紧急气道管理中发挥重要作用。
