Laryngospasm Flashcards
What does laryngospasm look like on DL?
Vocal cords are in midline position
What is the definition of a laryngospasm
Uncontrolled, involuntary muscular contraction of intrinsic laryngeal muscles producing aDduction of the vocal cords and glottic closure; Usually precipitated by a noxious stimulus in the airway or by stimulation of this right innervated by the Vegas nerve (CN X )
Afferent laryngeal fiber innervation is by the __.
CN X
efferent Laryngeal fiber innovation is ___
CN X
Pharyngeal innervation, afferent fibers are by ____ and the efferent fibers are by ____.
CN X
CN IX
What are 2 organs that are Associated with laryngospasm
Bladder (distention)
colon (distention)
Six etiologies for laryngospasm
- stimulation a base of tongue (0AW, suction)
- Stimulation of pharyngeal wall
- stimulation of trachea – Carina
- extubation
- aspiration of small volume
- Stimulation of Hollow visceral organs (Bladder,Colon)
What terminates laryngospasm? According to Dr. Hall (a.k.a. Dr. Magoo)
H.A.N.T.
Hypoxia (Patient desaturate to the point of no return and expires)
Anesthesia
Neuromuscular blockade
Time
According to Dr. hallway how do you treat laryngospasm?
Provide oxygen (fill up the circuit and airways)
establish airway patency by vigorous Jaw thrust
DO NOT apply positive pressure
can use Sux (10 mg) or propofol (20 – 30 mg)
According to Dr. Hall what are the two most important monitors during laryngospasm
Heart rate and pulse ox
True or false. You should suction the trachea immediately before Extubation.
false
In what phase of the breathing cycle should you extubated patient
At the end of deep, positive pressure inspiration
List bad outcomes for laryngospasm
Negative pressure pulmonary edema, hypoxemia, bradycardia, cardiac arrest, death
