Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Open cricothyrotomy is an emergent surgical procedure. It is performed to establish an airway access by passage of a tube through an incision in the cricothyroid membrane. This is a procedure of choice in the feared "can't intubate, can't ventilate" scenario - when all other forms of endotracheal intubation have failed and the spontaneous ventilation is worsening or has become impossible.

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...
FAQs
The cricothyroid membrane lies between the thyroid and cricoid cartilages, providing a recognizable anatomical target for emergency airway access. Accurate identification helps direct the opening toward the trachea and reduces the risk of misplaced access or airway injury. Training therefore emphasizes palpation and recognition of these cartilage landmarks before attempting the procedure.
The procedure bypasses an obstructed or inaccessible upper airway by establishing a direct route into the trachea. Once the tube is positioned, air can move through the new airway opening to support oxygenation and ventilation. This mechanism makes the technique particularly important when attempts to manage the airway through conventional routes have not succeeded.
Cricothyrotomy may create the airway opening through either an incision or a puncture of the cricothyroid membrane. The choice is linked to the equipment and technique used by the clinician, while both approaches aim to permit tube placement and airflow. Clinical training addresses these options so practitioners can select an appropriate method during an acute emergency.
Preparation centers on identifying the thyroid and cricoid cartilages, locating the intervening membrane, and selecting equipment suited to the intended incision or puncture technique. A tube must then be available to establish airflow after access is obtained. Training combines landmark recognition, equipment selection, and procedural technique because errors in any component can compromise the airway.
Clinicians consider this emergency approach when conventional airway management fails, especially in a “cannot intubate, cannot oxygenate” situation. Relevant clinical contexts include trauma, severe upper-airway obstruction, and other acute emergencies that prevent adequate oxygenation or ventilation. Its role is therefore as a rapid rescue option rather than a routine first-line airway procedure.
Important complications include bleeding, incorrect tube placement, and injury to airway structures. These problems can interfere with airflow or cause additional tissue damage, so clinical training stresses accurate landmark identification, appropriate technique, and confirmation that the tube has been positioned correctly. Recognizing these risks helps clinicians evaluate whether the procedure has achieved effective airway access.
