Stridor/Laryngospasm Flashcards
Causes/triggers for stridor:
obstruction airway edema vocal cord paralysis infection foreign body in airway
Inspriatory, expiratory and biphasic stridor-what does thismean:
Inspiratory: upper airway obstruction
Expiratory: lower airway obstruction
biphasic: mid tracheal lesions
KO treatment plan for stridor:
go evaluate patient full H&P-paying attention to when things started, which positions make it better CXR ABG Flexible bronchoscopy
If intubation in patient with stridor can be delayed, what are you giving/doing?
Oxygen by facemask
Head up positioning (45-90 degrees)
Nebulized racemic epinephrine
IV dexametahasone 4-8 mg given every 8-12 hours
Heliox: 70%helium, 30% oxygen: less dense than air o oxygen can lead to dramatic decreae in airway resistance and therefore improved ventilation
What to do with Laryngospasm?
Place patient on 100% O2 Remove irritating factor apply jaw thrust and PPV Deepen anesthetic with an IV agent such as fentanyl and propofol Give iv or topical lidocaine call for help if still not working Give SUX 10-50 mg IV or IM Attempt ot intubate if still not good.
Negative pressure pulmonary edema via laryngospasm:
from pt inspiring against closed glottis resulting in high intrapleural pressures resulting in pulmonary edema.
