Study Notes
Airway Management in Emergency Medicine
- Airway management is crucial in resuscitation and a core skill in emergency medicine.
- Emergency clinicians are primarily responsible for airway management.
- Rapid Sequence Intubation (RSI) is the most common method, but other techniques and devices exist, including management of difficult airways and rescue plans.
Indications for Intubation
- Intubation decisions are based on patient assessment and these three factors:
- Inability to maintain or protect the airway
- Ventilatory or oxygenation failure
- Predicted clinical deterioration
Failure to Maintain or Protect the Airway
- A patent airway is essential for ventilation and oxygenation.
- Airway maneuvers (repositioning, chin lift, jaw thrust) establish patency.
- The ability to handle secretions (e.g., swallowing) is a better predictor of airway protection than the gag reflex (which is unreliable).
- Patients requiring airway maneuvers or readily accepting oral airways generally need intubation for protection, unless temporary conditions exist.
- Level of consciousness and phonation ability assess upper airway integrity and consciousness.
Failure of Ventilation or Oxygenation
- Adequate gas exchange (oxygen and CO2 removal) is vital for organ function.
- Unreversable ventilatory failure or persistent hypoxemia necessitates intubation.
- Clinical assessment, pulse oximetry, and ventilatory pattern are crucial.
- Capnography is useful but not essential if pulse oximetry is reliable.
- Arterial blood gases (ABGs) aren't required or practical before emergency intubation.
- ABGs can be misleading and may delay intubation.
- Clinical improvement, despite abnormal ABG values, may not require intubation.
- Prolonged mechanical ventilation often mandates intubation, but non-invasive approaches (CPAP, BiPAP) can be successful for some situations.
Anticipated Clinical Course
- Conditions with high likelihood of worsening indicate intubation, even without an immediate threat.
- This includes early intubation for some overdoses and septic shock cases.
- Patients with significant trauma may require early intubation, even if initially stable.
- Penetrating neck trauma warrants early intubation if vascular/airway injury is suspected.
Difficult Airway Identification
- Intubation is typically straightforward, but difficult airways can arise.
- Cricothyrotomy rates are lower than was previously reported in emergency departments.
- Emergency department cricothyrotomy rates are still higher compared to operating rooms.
- Factors like difficult bag-mask ventilation (BMV) increase the likelihood of intubation difficulty.
- Preintubation assessment identifies anatomic features that indicate a difficult airway.
- This includes assessing laryngoscopy, intubation, BMV, extraglottic device (EGD) placement, and cricothyrotomy.
- Difficult to access airways often require non-neuromuscular blocking agents as the preferable approach to traditional methods.
- Awake intubation may be preferable when hypoxemia or metabolic acidosis is present and anatomic features make traditional methods challenging.
