Study Notes

Airway Management

  • Call for help early, tackle critical problems first, and prioritize supporting ventilation and circulation.
  • Airway obstruction is the most common emergency associated with sedation/anesthesia, leading to serious neurological and cardiovascular events.

Anatomy of Airway Obstruction

  • A patent airway consists of a soft palate, tongue, epiglottis, and trachea.
  • A blocked airway can be caused by the tongue, epiglottis, or other obstructions.

Predicting a Difficult Airway

  • Factors that predict a difficult airway include:
    • Class II skeletal malocclusion
    • Short neck
    • Obese patient
    • Macroglossia
    • Limited range of motion (LROM) cervical neck
    • LROM temporomandibular joint (TMJ)
    • History of sleep apnea

Airway Obstruction Symptoms

  • "Rocking boat" breathing
  • Supra-sternal retraction

Basic Airway Management

  • Head-tilt chin-lift maneuver
  • Jaw-thrust maneuver
  • Triple airway maneuver (head-tilt, chin-lift, and jaw-thrust)

Oropharyngeal Airways (OPA)

  • Use the correct size of OPA, measured from the incisors to the angle of the mandible.
  • OPA placement can relieve physical obstruction by displacing the tongue from the posterior pharynx.

Emergency Equipment

  • Oxygen tank with a regulator capable of variable flow up to 15 liters per minute
  • Positive pressure breathing device
  • Pocket mask
  • Automated external defibrillator (AED)
  • Blood pressure and stethoscope
  • Emergency medications (e.g., aspirin, asthma inhaler, diphenhydramine, epinephrine, glucose paste, midazolam)

Emergency Medications

  • Aspirin 81mg (chewable tablet) for acute coronary syndrome, chest pains, angina, suspected myocardial infarction (MI), or "heart attack"
  • Asthma inhaler (albuterol) for acute asthmatic bronchospasm
  • Diphenhydramine (Benadryl) for allergic reactions and anaphylaxis
  • Epinephrine (1:1000) for severe allergic reactions and anaphylaxis
  • Glucose paste for hypoglycemia
  • Midazolam (Versed) for sedation and anxiety

Emergency Response

  • Follow the instructions for administration of each medication
  • Use 100% oxygen for asthma and bronchospasm
  • Administer EpiPen for severe allergic reactions and anaphylaxis
  • Protect the patient from physical contact and maintain a patent airway during seizures
