Major Causes of Upper Airway Emergencies
- Anatomical & Mechanical
- Allergic
- Infectious
- Traumatic & Caustic
Anatomical & Mechanical Emergencies
- Foreign Bodies & other Obstructions
- Tumors & post surgical changes
- Congenital & other Disorders
Foreign Bodies & other Obstructions
- Food or other objects
- Tongue = Unconscious Pts
- Blood, Vomit, or Phlegm = Can lead to aspiration
Foreign Bodies & other Obstructions
TX
Food or Object:
- Cough
- Magill Forceps or Finger Swipe
- Heimlich Maneuver or Back Blows
- Compressions
- Intubation
- Cricothyrotomy
Tongue:
- Head Tilt or Jaw Thrust
- OPA
- Supraglottic Airway
Blood, Vomit, or Phlegm:
- Suction
- Supraglottic Airway or Intubation
Tumors & Post Surgical changes
- Chrondromas:
- Firm nodules located in the tracheal cartilage rings
- Can turn cancerous - Hemangiomas:
- Growth made of extra blood vessels in the trachea or larynx - Papillomas:
- Cauliflower-like tumors caused by HPV, most common benign tracheal tumor in children - Squamous Cell Carcinoma:
- Most common due to smoking
- Penetrates the mucosal lining of the trachea causing ulceration & bleeding - Adenoid Cystic Carcinoma:
- 2nd most common malignancy of the trachea that starts in the salivary glands
- Eventually close off the airway as they progress
Congenital & other Disorders
- Laryngomalacia:
- Birth defect in which the soft, immature cartilage of the upper larynx collapses over the vocal cords causing partial obstruction - Vocal Cord Palsy:
- Vocal cords don’t open or close properly - Subglottic Stenosis:
- Narrowing of the cricoid below the vocal cords - Subglottic Hemangioma:
- Tumor composed of a large mass of blood vessels below the vocal cords
- Can lead to airway obstruction & respiratory distress - Tracheomalacia:
- Malformation of the cartilage in the trachea
- The trachea narrows or collapses causing to decreased airflow - Myasthenia Gravis:
- Weakens striated muscle & usually affects those innervated by the bulbar cranial nerves
- Weakens these bulbar & other upper airway muscles leading to upper airway obstruction - Parkinson’s disease:
- This chronic neurodegenerative condition can cause upper airway obstruction, which is associated with laryngeal spasms - GERD:
- Stomach acid or undigested food rises into the esophagus and sometimes into the larynx, which can trigger a laryngospasm
Allergic Emergencies
- Anaphylaxis:
Swelling of the soft tissues of the mouth & throat, including the:
- lips
- tongue
- hypopharynx
- larynx
- vocal cords
*Due to a systemic release of histamine from an allergen exposure
- Angioedema:
- Swelling of the deeper layers of the skin & tissue
- Can effect any part of the body, but often affects the face, lips, eyes, genitals, hands, & feet
Anaphylaxis TX
- 0.01mg/kg IM Epi (1:1):
- 0.15mg for Peds <30kg (8 y/o or younger)
- 0.3mg for Peds/Adults >30kg (9 y/o or older) - Breathing TX:
- 2.5mg of Albuterol (3x)
- 0.5mg of Atrovent (1x) - 20ml/kg Fluid for hypotension
- Benadryl 1mg/kg IV/IM (50mg Max dose)
- Solumedrol 2mg/kg IV/IM (125mg Max dose)
Angioedema TX
- Benadryl 1mg/kg IV/IM (50mg Max dose)
- IM Epi (1:1)
- TXA?
- Solumedrol?
Infectious Emergencies
- Epiglottis
- Croup
- Retropharyngeal & Prevertebral Abscess
- Peritonsillar Abscess
- Ludwig’s Angina
Epiglottis
Inflammation of the epiglottis, commonly caused by infections (HIB) & affects peds 3-7 y/o
S/S:
- High fever
- Inspiratory Stridor (lower pitch than croup)
- Painful swallowing & drooling
- Muffled Voice
- Rapid progression of respiratory distress (Tripoding)
TX:
1. Monitor breathing & O2 levels, look out for signs of that may indicate need for intubation
2. Administer blow by O2 & keep the Pt Calm
3. Position the Pt
4. Have equipment ready
5. Transport Fast
Croup
Affects PEDs 16 months - 3 years old
Caused by a viral infection and typically has a slower onset of symptoms
S/S:
-barking seal cough
-Low-grade fever
TX:
1. Nebulized 3ml of 1:1 Epi
2. Solumedrol 2mg/kg IV/IM (Max 125mg)
3. Consider IM Epi 1:1
Traumatic & Caustic Emergencies
- Penetrating or Blunt force Trauma
- Thermal Burns
- Caustic Ingestion
- Drowning
- Inhaled Toxins
