  2. Distal end of tube has a 30 degree bend

  • Preparation
  1. Direct Laryngoscopy
    1. Bougie may be used without adjusting curvature
  2. Hyperangulated blade (e.g. glidescope) technique
    1. Bougie coiled in pocket will gain a curvature to better navigate anteriorly into the airway
    2. Assistant may need to apply backward pressure on trachea to assist with passage
  1. Insert Laryngoscope in standard fashion
    1. Visualize cords (or at least arytenoids, Cuneiform and corniculate cartilages)
  2. Insert bougie through cords
    1. Bougie may catch at the laryngeal inlet
      1. Rotate the bougie tip by 180 degrees
      2. Advance the bougie and then rotate the bougie back 180 degrees (so tip faces anteriorly)
  3. Pass the Endotracheal Tube over the bougie in seldinger technique
  4. Remove the bougie
  • Technique
  • Blind method
  1. Insert the bougie with the 30 degree bend (coude tip) pointing anteriorly
  2. Feel the bougie tip slide over the tracheal rings
  3. If Endotracheal Tube is advanced past the 50 cm mark, it it not in the trachea
  • Efficacy
  • Pearls
  1. Practice using Elastic Bougie when it is not needed (routine, straight forward insertion)
