An extraglottic airway is reserved for deeply unconscious patients needing ventilation.

A quick breath in a high-stakes moment: the extraglottic airway in Tactical Combat Casualty Care

On the move, under stress, with gear clanking and the clock ticking—that’s the battlefield reality. In those moments, securing a patient’s airway can tilt the balance between life and not enough oxygen staying in the bloodstream. That’s where the extraglottic airway (EGA) steps in. It’s a simple tool, but when used at the right time, it buys you a steady path to ventilation and makes a tough situation a bit more manageable.

What exactly is an extraglottic airway, and when do you pull it out?

Think of an extraglottic airway as a bridge between a mask and a full airway control. It sits above the glottis (hence “extraglottic”) and creates a direct channel for air to reach the lungs. It’s designed for rapid airway management, especially when you suspect the patient can’t protect their own airway or maintain adequate breathing.

The big rule in the field is clear: use it for a deeply unconscious casualty who needs ventilation. If someone is awake, coughing, talking, or able to protect their airway, an EGA is not the right tool. Likewise, if respiratory distress isn’t tied to a failing airway (for example, a treatable lung issue or a reversible problem), you’d address that cause directly rather than forcing an artificial airway. And in the chaos of trauma, you don’t automatically reach for an EGA just because there’s injury—prioritizing airway protection, breathing, and circulation in the right order remains the compass.

Why this device matters in Tier 3 or field-level care

In the field, you want something reliable that doesn’t require perfect visibility or six hands to place. An EGA gives you a secure conduit for bag-valve-mask ventilation when securing a true endotracheal tube isn’t feasible or would take too long. It’s not a cure-all, but it’s a practical, time-saving option that helps you buy oxygen delivery and give the patient a chance to recover the basics: adequate breathing and oxygen saturation.

Getting the right mindset means recognizing the EGA isn’t a fix for every breathing problem. If the casualty is conscious and can breathe on their own, the airway can stay as is. If there’s a risk of aspiration, or if GI contents might be a problem (think vomiting or significant trauma), you weigh the benefits of an airway device against the risk of gastric inflation and other complications. The key is to move with purpose and adapt to the moment.

What are the actual devices we’re talking about?

Extraglottic airways come in several flavors, with a few pros and cons depending on your environment and training. In practice, you’ll encounter devices like:

• Laryngeal mask airways (LMA): A versatile option that sits over the laryngeal inlet. It’s quick to insert and familiar to many crews, but it may not be ideal in some trauma scenarios where neck stability is a concern.

• King LT-D and similar suctioned or suction-enabled supraglottic devices: These are designed for secure placement with a dedicated airway tube and a time-tested track record in both civilian and military settings.

• i-gel and other gel-seal supraglottic devices: These can form a seal with minimal lubrication and less airway manipulation, which can be helpful when you’re moving, wearing gloves, or dealing with edema or blood.

The common thread across these options is simplicity: insertable with minimal equipment and a reasonable success rate in a variety of field conditions. Endotracheal intubation remains the gold standard for definitive airway control, but it’s more technically demanding, requires more time, and can be compromised by facial trauma, difficult anatomy, or a less-than-ideal environment. An EGA provides a dependable bridge when the clock is ticking and the goal is steady ventilation.

How to use it in the field without turning it into a science project

Let me explain the practical flow you’ll likely follow, keeping things simple and safe:

• Prepare and position: Stabilize the spine if trauma is suspected, and place the patient in a position that optimizes airway access. If you’re able, perform a quick chin-lift or jaw-thrust to clear the airway before insertion, but don’t waste precious seconds on perfect technique if the patient’s airway is compromised.

• Choose the device based on the situation: If you’ve trained with King LT-D, i-gel, or an LMA, select the one you’re most confident placing in the moment. Practice has shown that familiarity reduces insertion time and errors.

• Insert with confidence: Follow the manufacturer’s guidance for your device. In most cases, you’ll insert along the midline and confirm the device is seated properly. If the patient regurgitates or spits, pause briefly to clear the airway before resuming.

• Confirm ventilation: The proof is in the outcomes. Look for chest rise, listen for breath sounds, and monitor oxygen saturation if you have a pulse oximeter. If available, capnography (ETCO2) is a strong confirmation that airflow is reaching the lungs.

• Secure and monitor: Once you’re ventilating well, secure the device to prevent dislodgement during movement or transport. Observe again for air leakage, gastric insufflation, or signs of airway obstruction.

• Decide on the next step: In many field settings, an EGA is a bridge to definitive airway control in a more controlled environment (helicopter evacuation, forward operating base, or medical facility). If ventilation remains inadequate, reassess: reposition the device, suction as needed, and be prepared to escalate if triage allows.

A few practical cautions to keep in mind

• It’s not for everyone: Conscious patients who breathe adequately don’t need this. It’s specifically for those who cannot protect their airway and require ventilation.

• Timing matters: In trauma, neck or spinal injuries complicate airway management. If you suspect a cervical spine injury, maintain inline stabilization and proceed with a technique that minimizes neck motion.

• Watch for gastric inflation: An EGA can push air into the stomach. If you see distention, reduce the rate and reassess technique or suction as needed.

• Not a substitute for skillful assessment: The device is a tool, not a replacement for good clinical judgment. If ventilation isn’t improving after placement, consider other factors: chest injuries, airway obstruction, or the need for a different approach.

Common pitfalls and how to avoid them

• Insertion struggles under stress: High adrenaline can make steady hands hard to find. Slow down just enough to ensure a proper seal. If you miss on the first attempt, reassess airway anatomy and reattempt without force.

• Poor seal in a noisy environment: In the field, seals may be compromised by movement, debris, or edema. Recheck tube position and ensure there’s a good seal before pushing more air.

• Overlooking CPR timing: If a casualty isn’t breathing and not responding, ventilate, but don’t neglect chest compressions when indicated. The airway is essential, but circulation and oxygen delivery are equally critical.

• Relying on a single device: The terrain, weather, or casualty’s anatomy may favor one EGA over another. Be comfortable with more than one option and switch if the situation demands it.

Rhetoric and realism: training, drills, and the human element

For professionals, muscle memory saves lives. The best field teams drill with their preferred devices until the steps feel automatic, almost second nature. In training, you’ll run through scenarios that simulate real-world chaos: low light, wind, movement, and the constant hum of a distant helicopter. The aim isn’t to memorize a script but to build confidence and adaptivity.

A practical digression worth keeping in mind: even with the best gear, the patient’s journey is not just technical. You’re carrying not only the airway but also the emotional weight of a person in crisis. A calm, deliberate approach—clear communication with your team, concise updates to medevac, and a steady line of reassurance to the patient when feasible—can reduce panic and improve outcomes.

Real-world pearls you can carry into your next drill

• Know your devices well enough to choose quickly. If you rely on i-gel, practice inflating, seating, and confirming ventilation. If you’re more comfortable with a King LT-D, drill the insertion angle, cuff inflation, and securing method.

• Capnography is a game-changer when available. A quick waveform check can tell you far more than a visual assessment alone.

• Document smartly in the field. Note time of insertion, device type, and ventilation success. When you get to the next stage of care, this information helps the team pick up where you left off.

• Practice comfort with “the bridge” mindset. The EGA is a bridge tool; it’s not the finish line. Be ready to transition to a more definitive airway when the situation allows.

Putting it all together: a concise takeaway

The extraglottic airway is a practical, fast-acting option for airway management in the field. It’s specifically designed for deeply unconscious casualties who need ventilation and cannot protect their own airway. It’s not for a conscious patient who is breathing well, nor is it a universal fix for every respiratory problem. In trauma, where time and clarity count, an EGA helps you establish a secure airway quickly and move forward with ventilation while you coordinate evacuation and further treatment.

If you’re part of a team that trains together, you’ve likely seen how this device reduces the friction that comes with airway management in rough conditions. The goal isn’t to memorize every detail but to understand the role of the EGA, know when to apply it, and practice until you can place it with confidence, even under pressure.

So next time you’re in a field exercise or a standby scenario, remember the simple rule at the heart of its use: deeply unconscious casualty needing ventilation. If that’s the case, the EGA is your tool to keep air moving, oxygen flowing, and your patient in a better position to recover.

If you’d like, I can tailor this into a quick-reference guide for your team, or lay out a drill plan that cycles through different EGA devices and scenarios. Either way, the focus stays the same: practical airway management that keeps pace with the realities of the field—clear, effective, and ready when the moment calls.
