II. Indications
- Laryngospasm (especially with Ketamine in children)
III. Mechanism
- Unclear (may be due to jaw-thrust motion or vagal nerve stimulation)
IV. Risk Factors
- Laryngospasm with Ketamine is more common in children, but still rare
V. Technique
- Bilateral Landmarks
- Maneuver
- Press on both sides, at the apex of each notch
- Push inward and anterior at each of the 2 notches
- Effect
- Laryngospasm typically improves within 1-2 breaths
VI. Management: Alternative Measures for Laryngospasm with Consious Sedation or Induction
- See Ketamine
- Jaw Thrust Maneuver (create an "underbite")
- Two-handed bag-valve mask (BVM) with a second provider applying the mask (with C-E positioning)
- Paralysis (Rocuronium or Succinylcholine) and intubation
