To the Editor: Direct laryngoscopy remains the technique of choice to facilitate tracheal intubation. Alternative intubation techniques are required whenever an airwayis deemed difficult or when tracheal intubation is unsuccessful. The retrograde intubation (RI) technique is an option for controlling the airway and is listed on the American Society of Anesthesiology difficult airway algorithm. 1We use a new technique for RI that utilizes an epidural kit (Braun, Bethlehem, PA, USA) and an 86-cm long Cook airway exchange catheter (CAEC)(Cook Critical Care, Bloomington, IN, USA), which are both commonly found in an anesthesia work room. In preparation, 20 cm of the CAEC are cut off the caudal end making it just short of a gum elastic bougie. Under standard monitoring, the patient is positioned supine with the neck in the neutral position or slightly extended. The patient’s airway is the topicalized with local anesthesia, and sedation may be titrated to effect while sterile solution is applied to the neck. Next, the cricothyroid membrane is punctured with a 17G epidural needle in a 45º angle with the bevel pointing rostrally. An epidural catheter (EC) is used for retrograde passage into the oral cavity. Pulling out the tongue and using a Magill forceps usually helps to retrieve the EC. The caudal end of the EC must be secured with a clamp or by an assistant. The EC is then threaded through the central lumen of the shortened CAEC and is secured at the rostral end once it appears. The CAEC is guided over the EC through the vocal cords. Pulling out the tongue and cricoid pressure may facilitate tracheal intubation. Once the CAEC stops because the EC prevents further passage, the EC is released at the rostral end and the CAEC is inserted carefully further into the trachea. Breath sounds through the CAEC may be heard, if the patient is still breathing spontaneously. An endotracheal tube (ETT) is then guided over the CAEC into the trachea. Laryngoscopy may facilitate this passage.
