Bougie
Contents
Overview
- First described by Macintosh in 1949 (was originally using a urinary catheter)[1]
- Modern form introduced in 1970's as Eschmann Endotracheal Introducer; it is neither gum, nor elastic nor a bougie [2]
- Made of polyester threads and outer resin layer
- Typically 60 cm, malleable, and with 60 degree angulated coudé tip
Benefits and Applications
- BEAM trial showed 98% first-pass success using a bougie compared to 87% using stylet for intubation.[3]
- Given smaller diameter compared to ETT, allows for increased visualization when passing through vocal cords
- Can use "tracheal clicks" and "hold-up signs for tactile confirmation of correct placement
- Especially helpful with Cormack-Lehane views II-IV (can be passed blind and placement confirmed with tactile feedback)
- Used in "scalpel-bougie-tube" cricothyrotomy technique
- Can assist blind digital intubation
- Can rotate 90° CW or CWW to selectively intubate non-bleeding lung in cases of massive hemoptysis[4]
- Compatible with Macintosh blade and standard geometry video larygoscopes
Complications
- Theoretical risk of pneumothorax with hold-up sign
- Case reports of airway trauma secondary to bougie use
- However, there is no high-quality evidence to suggest bougie use leads to increased mechanical complications of intubation[5]
Procedure
- Obtain view with Mac blade laryngoscope (direct or video with Macintosh blade)
- Pass bougie - confirm with tracheal clicks and/or hold up sign
- Have assistant "railroad" tube over bougie
- Alternatively can use preload ETT over bougie for single-operator using "kiwi" grip
Pitfalls
- Removing laryngoscope before railroading ETT can cause difficulty in passing the tube
- If resistance is met, bevel is abutting the posterior cartilages, retract the tube 1-2 cm and rotate 90° CCW, then advance tube
