What is the purpose of the mnemonics LEMON, ROMAN, RODS, and SMART in airway management?
What is the purpose of the mnemonics LEMON, ROMAN, RODS, and SMART in airway management?
They assist in the assessment of potential difficult intubation and airway management strategies.
Why is it crucial to confirm tube placement using end-tidal carbon dioxide (ETco2) after intubation?
Why is it crucial to confirm tube placement using end-tidal carbon dioxide (ETco2) after intubation?
It ensures proper ventilation by detecting adequate exhaled CO2, indicating correct placement in the trachea.
What is the preferred method of airway management for emergency department patients when time allows?
What is the preferred method of airway management for emergency department patients when time allows?
Rapid sequence intubation (RSI) is the airway management method of choice.

Study Notes
Emergency Airway Management in the ED
- Predicting deterioration is vital before intubation, especially for transfers or diagnostic tests.
- Videolaryngoscopy (VL) has improved intubation success rates over direct laryngoscopy (DL).
- Pre-intubation assessment for difficult intubation, bag-mask ventilation (BMV), extraglottic devices (EGD), and cricothyrotomy is crucial before neuromuscular blockers.
- LEMON, ROMAN, RODS, and SMART mnemonics assist in this assessment.
- Physiological stability is key. Cardiovascular optimization (fluids, blood, pressors) helps prevent circulatory collapse and cardiac arrest.
- Rapid Sequence Intubation (RSI) is the preferred method for uncomplicated ED patients.
- Tube placement confirmation with end-tidal carbon dioxide (ETCO2) is essential post-intubation. Low ETCO2 suggests esophageal intubation.
- VL improves first-attempt success compared to DL. Fewer adverse events and better outcomes are seen with faster intubation.
- Cricothyrotomy is performed in "can't intubate, can't oxygenate" situations. Delays increase the risk of hypoxic injury.
- Etomidate is the most common neuromuscular blocking agent (NMBA) in RSI. Rocuronium or succinylcholine are also options, with rocuronium having a longer duration but potentially fewer adverse effect.
- Extraglottic devices are used less in emergency situations, but are options for oxygenation when intubation fails.
