Deluxe Cricothyrotomy Simulator

Landmarks include:

• Thyroid cartilage
• Cricoid cartilage
• Cricoid membrane

Inflation of a simulated lung verifies correct placement. Each airway can be used multiple times before replacement. The number of uses will depend on whether a needle or surgical cricothyrotomy is being performed, the instruments used and the skill of the practitioner.

About Cricothyrotomy

A cricothyrotomy is often used as an airway of last resort given the numerous other airway options available including standard tracheal intubation and rapid sequence induction, which are the common means of establishing an airway in an emergency scenario. Cricothyrotomies account for approximately 1% of all emergency department intubations and are used mostly in patients who have experienced a traumatic injury.

Indications

Some general indications for this procedure include:

• Inability to intubate
• Inability to ventilate
• Inability to maintain SpO2 >90%
• Severe traumatic injury that prevents oral or nasal tracheal intubation

Contraindications

• Inability to identify landmarks (cricothyroid membrane)
• Underlying anatomical abnormalities such as a tumour or severe goitre
• Tracheal transection
• Acute laryngeal disease due to infection or trauma
• Small children under 12 years old (a 10–14 gauge catheter over the needle may be used)

Procedure

The procedure was first described in 1805 by Félix Vicq-d’Azyr, a French surgeon and anatomist. A cricothyrotomy is generally performed by making a vertical incision on the skin of the throat just below the laryngeal prominence (Adam’s apple), then making another transverse incision in the cricothyroid membrane which lies deep to this point. A tracheostomy tube or endotracheal tube with a 6 or 7-mm internal diameter is then inserted, the cuff is inflated, and the tube is secured. The person performing the procedure might utilise a bougie device, a semi-rigid, straight piece of plastic with a one-inch tip at a 30-degree angle, to provide rigidity to the tube and assist with guiding its placement.

Confirmation of placement is assessed by bilateral auscultation of the lungs and observation of the rise and fall of the chest. Alternatively, bedside ultrasound has been used increasingly to guide the procedure and confirm the placement of the tracheal tube. It may especially be helpful in situations where a neck collar is placed.

Training

This procedure is rarely performed, given advancements in airway technique and adjuncts, and thus simulated training is of paramount importance to correctly perform this procedure under a high-stress situation.
