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.
