What Current TCCC Guidelines Say About Airway Management

The Tactical Field Care airway sequence in the current TCCC Guidelines, published May 1, 2026 by the Committee on Tactical Combat Casualty Care, is concise: assess for an unobstructed airway, position the casualty, suction if available, and if those measures fail, perform a surgical cricothyroidotomy. Nasopharyngeal and supraglottic airways are not part of that TFC sequence except in one narrow circumstance.

That is a significant departure from how airway management was taught for over a decade, and it remains a real point of divergence between military and civilian tactical medicine.

The Current TFC Airway Sequence

Tactical Field Care airway management proceeds as follows: assess for an unobstructed airway. A conscious casualty is allowed to assume any position that protects the airway, including sitting up and leaning forward. An unconscious casualty is placed in the recovery position, head tilted back, chin away from the chest. Suction is used if available. If those measures fail to clear an obstruction from facial fractures, direct airway injury, blood, deformation, or burns, the casualty receives a surgical cricothyroidotomy.

Two cricothyroidotomy techniques are specified: bougie-aided open surgical and standard open surgical, both using a flanged and cuffed airway cannula with an outer diameter under 10 millimeters, an internal diameter of 6 to 7 millimeters, and 5 to 8 centimeters of intratracheal length. Placement is verified with continuous EtCO2 capnography. Lidocaine is used if the casualty is conscious. SpO2, EtCO2, and airway patency are reassessed frequently, since airway status can change over time.

The one retained role for the NPA sits in the respiration and breathing section, not airway management. If a casualty has impaired ventilation and uncorrectable hypoxia with oxygen saturation below 90 percent, or below 92 percent with moderate or severe traumatic brain injury, the guidelines call for considering a properly sized nasopharyngeal airway and ventilating with a 1,000 milliliter resuscitator bag valve mask. Outside that specific indication, the NPA has no place in Tactical Field Care airway management. Supraglottic and extraglottic airway devices are not in the TFC sequence at all.

Why the Sequence Changed

The shift traces to a multiyear CoTCCC review published by Shaw et al. in the Journal of Special Operations Medicine. The review identified a foundational problem: most existing research on airway adjuncts was conducted in civilian EMS settings focused on out-of-hospital cardiac arrest, a population and environment that differ substantially from combat trauma.

Several combat-specific factors shaped the new sequence. A casualty obtunded enough to tolerate an extraglottic airway in the field is likely in profound hemorrhagic shock or has a significant traumatic brain injury, and survival in that clinical picture is poor regardless of airway intervention. Most military medics lack the capability to perform drug-assisted airway management, which limits the value of extraglottic devices compared to their role in civilian advanced airway protocols. Maxillofacial trauma, common in combat, can prevent effective device placement, and the packaging for those devices occupies considerably more space than a modern cricothyroidotomy kit.

The Surgical Airway Problem Nobody Is Ignoring

C-TECC's position statement on supraglottic airway devices named the tension in this sequence directly. Surgical cricothyroidotomy success rates run 67 percent in military environments and 52.9 percent in civilian settings, according to the data the position statement cites. That is a procedure that fails roughly one in three times in the best-trained environments and nearly one in two in civilian prehospital settings.

The current guidelines respond with more structure around the procedure rather than more alternatives to it: specified cannula dimensions, two named techniques, mandatory continuous EtCO2 verification, and lidocaine for conscious casualties. Removing intermediate airway options puts more weight on getting the surgical airway right.

Where TCCC and TECC Diverge

C-TECC reviewed the same evidence the CoTCCC reviewed and reached a different conclusion for civilian tactical emergency medicine. The position statement states plainly that TECC guidelines will continue to incorporate supraglottic airway devices in the civilian tactical airway algorithm.

The reasoning is grounded in real operational differences. Civilian TECC practitioners often have access to drug-assisted airway management, which extends the value of supraglottic devices well beyond what a military medic can do in the field. Scope of practice in civilian EMS varies by jurisdiction, and the National EMS Scope of Practice Model explicitly limits cricothyroidotomy to the paramedic level. According to 2022 data, only about 25.6 percent of nationally registered EMS responders held paramedic certification. A protocol that defaults to surgical airway in a system where most practitioners cannot legally perform one is not operationally viable.

For tactical medics working in civilian law enforcement environments, the gap between these frameworks matters. Training under TCCC while operating under TECC protocols creates a real possibility for confusion if the distinction is not explicitly addressed. Personnel need to know which guidelines govern their training, which govern their operations, and where the two differ.

What It Means for Training

Any course that presents NPAs or supraglottic devices as standard Tactical Field Care airway adjuncts is teaching a sequence that is no longer current. Kit standards follow the same logic: bag valve masks in TCCC-aligned kits should be 1,000 milliliters, and continuous EtCO2 capnography should be present in any kit that includes a cricothyroidotomy setup. For units whose personnel train to TCCC but operate under TECC or local agency protocol, that gap is the conversation worth having explicitly rather than assuming everyone already knows which set of rules applies.

Two Credible Organizations. Two Different Answers.

The CoTCCC and C-TECC reviewed the same evidence and reached genuinely different conclusions. That is not a failure of either process. It reflects a real difference in operational environment: what is appropriate for a combat medic with no drug-assisted airway options is not automatically appropriate for a civilian tactical medic with paramedic-level training and a different scope of practice. The current TCCC guidelines reflect the environment they were written for. The C-TECC position reflects the environment it was written for. The problem is when personnel train in one framework and operate in another without anyone making the distinction explicit.
