Background

In clinical anesthesia or rescue of critical patients, especially when the tracheal catheter is difficult to be inserted into the trachea in difficult airways, the trachea cannula is required to be inserted in a retrograde way through the larynx. The method comprises the steps of firstly puncturing the cricothyroid membrane, placing a silk thread with a guiding function in the glottis direction, pulling the silk thread out through the oral cavity or the nasal cavity, and then guiding the tracheal catheter into the trachea. The method is simple to operate and easy to master, and the required instruments are common and easy to obtain. The guiding thread used in the above procedures is generally an epidural catheter or a guiding thread steel wire for central venipuncture. The epidural catheter has the advantages of being relatively soft and capable of being deformed randomly. When the tracheal catheter enters the glottis and continues to go deep along the trachea through the level of the cricothyroid membrane, the epidural catheter easily goes into the trachea along with the penetration of the tracheal catheter.
