What is an esophageal tracheal dual lumen airway?

The Combitube—also known as the esophageal tracheal airway or esophageal tracheal double-lumen airway—is a blind insertion airway device (BIAD) used in the pre-hospital and emergency setting. It is designed to provide an airway to facilitate the mechanical ventilation of a patient in respiratory distress.

When would you use a dual lumen airway?

The Esophageal/Tracheal Double Lumen Airway (ETDLA) or Combitube is a secondary option to endotracheal intubation in providing a method of ventilating patients who are unconscious, apneic and pulseless. The ETDLA does not require direct visualization of the airway or significant manipulation of the neck.

Where is a dual lumen airway placed?

Esophageal-Tracheal Double-Lumen Airways. The Combitube (Fig. 49.14) is a double-cuff, double-lumen tube. The oropharyngeal balloon is in the middle portion of the tube, while the tracheal cuff is at the end. It is inserted blindly until the printed rings lie at the teeth.

When is a Combitube contraindicated?

Contraindications to use of the esophageal tracheal Combitube use include esophageal obstruction or other abnormality, ingestion of caustic agents, upper airway foreign body or mass, lower airway obstruction, height less than 4 feet, and an intact gag reflex.

When should you use a Laryngeal Mask Airway LMA in the field?

Elective ventilation: The laryngeal mask airway (LMA) is often used for short surgical procedures in which endotracheal intubation is not necessary. Difficult airway: In some patients where endotracheal intubation fails, the LMA can be used as a rescue device for maintaining the airways.

Why would you use a Combitube?

The Combitube is a twin lumen device designed for use in emergency situations and difficult airways. It can be inserted without the need for visualization into the oropharynx, and usually enters the esophagus.

Is there a double lumen esophageal tracheal airway?

Esophageal-Tracheal Double-Lumen Airways. In the era of VL, esophageal-tracheal double-lumen airways are rarely encountered in the hospital but are still used by emergency medical personnel in the field.

What is the esophageal tracheal airway (Combitube)?

The esophageal tracheal airway/ Combitube is one of several extraglottic airways currently being marketed. Other notable devices are the CobraPLA® and the COPA® (cuffed oropharyngeal airway). The esophageal tracheal airway or Combitube is a double-lumen tube with two cuffs which has been around since 1987.

What is the difference between the esophageal-tracheal double lumen tube and King laryngeal tube?

The esophageal-tracheal double lumen tube (Combitube®) and the King laryngeal tube are supraglottic airway devices (also called retroglottic airway devices). .) The esophageal-tracheal double lumen tube (Combitube®) and the King laryngeal tube are twin-lumen tubes that have fundamental similarities:

What are the advantages of an esophageal tracheal tube?

The esophageal-tracheal double lumen tube and King laryngeal tube have some advantages over other methods of ventilation: Unlike endotracheal tubes, they can be successfully inserted blindly and by inexperienced operators. , they avoid the difficulties of attaining and maintaining an adequate face-mask seal.
