In the Field
Cricothyroidotomy is the airway intervention of last resort. It is also one of the most consequential skills a tactical medic can carry, because it is the difference between a patient who lives and a patient who dies of airway compromise from a face wound, severe burns, or anatomy that defeats every other approach. The procedure is straightforward in principle and unforgiving in practice. It requires real training, sterile or near-sterile equipment, and the willingness to commit to the cut once the decision is made.
Common Mistake
Hesitating on a cricothyroidotomy in a patient with definite airway failure, when delay reduces the chance of success and patient survival.
Technical Detail
A cricothyroidotomy is an emergency surgical airway procedure that creates a direct opening through the cricothyroid membrane, a thin layer of tissue between the thyroid cartilage (the laryngeal prominence or "Adam's apple") and the cricoid cartilage immediately below. The opening provides a direct route for ventilation, bypassing the upper airway above the larynx.
Indications. Cricothyroidotomy is indicated when a patient cannot be ventilated by less invasive means and a less invasive airway is not achievable. Common scenarios include:
Severe maxillofacial trauma, where blood, broken teeth, or distorted anatomy prevent oral or nasal airway access.
Severe airway burns or inhalation injury with progressive swelling that has closed the upper airway.
Failed intubation in a patient who cannot be effectively bag-mask ventilated.
Anatomic obstruction (foreign body, mass) above the cricothyroid membrane that cannot be cleared.
The decision to perform a cricothyroidotomy is generally made when conventional airway management has failed and the patient will die without an airway.
Technique. The classic surgical cricothyroidotomy involves:
Identifying the cricothyroid membrane by palpation. The thyroid cartilage is identified, then the small depression directly below it.
Stabilizing the larynx with the non-dominant hand.
Making a vertical or horizontal incision through the skin and through the cricothyroid membrane.
Inserting a tube (typically a 6.0 to 7.0 mm cuffed endotracheal tube or a dedicated cricothyroidotomy tube) through the opening into the trachea.
Securing the tube and confirming placement by chest rise, breath sounds, and end-tidal CO2 if available.
Several variations exist, including kit-based approaches that use specialized devices to simplify the steps. CoTCCC reviews and recommends specific cricothyroidotomy kits for tactical use.
Provider scope. Cricothyroidotomy is a provider-level procedure, generally restricted to:
Combat medics, corpsmen, and tactical paramedics with formal training in surgical airway procedures.
Physicians, nurse practitioners, physician assistants, and paramedics with both training and applicable scope of practice authorization.
State EMS scope of practice rules and individual service medical director protocols govern when and how civilian tactical paramedics may perform this procedure.
Aid bag specifications. Cricothyroidotomy kits, including dedicated devices such as the H&H Cric-Key or scalpel-and-tube combinations, are standard contents of advanced tactical medic aid bags. They are not contents of basic IFAKs.
Pediatric considerations. Cricothyroidotomy is generally not recommended in children under approximately 8 to 12 years of age because the cricothyroid membrane is poorly developed. Pediatric airway emergencies are managed with alternative approaches.
