Cricothyrotomy
Cricothyrotomy
Cricothyrotomy (pronounced: kri-ko-thy-ROT-o-my) is a surgical procedure that is performed to secure an airway in emergency situations.
Etymology
The term "Cricothyrotomy" is derived from the Greek words "krikos" meaning ring, "thyreos" meaning shield, and "tome" meaning cutting.
Procedure
In a Cricothyrotomy, an incision is made through the skin and the cricothyroid membrane to establish a patent airway. This procedure is typically performed when endotracheal intubation is not possible or contraindicated.
Indications
Cricothyrotomy is indicated in cases of severe upper airway obstruction or trauma, where other methods of securing the airway are not possible or have failed. This includes conditions such as anaphylaxis, epiglottitis, and severe facial trauma.
Complications
Possible complications of a Cricothyrotomy include bleeding, infection, subcutaneous emphysema, damage to the larynx or trachea, and incorrect placement of the tube.
