The laryngeal tube (also known as the King LT) [1] is an airway management device designed as an alternative to other airway management techniques such as mask ventilation, laryngeal mask airway, and tracheal intubation.
This technique involves the use of a flexible fiberoptic bronchoscope for visualization of the vocal cords. The bronchoscope can be passed directly into the trachea and the endotracheal tube can be threaded over the bronchoscope into position. This technique has various advantages over direct laryngoscopy and video laryngoscopy techniques.
A laryngeal mask airway has an airway tube that connects to an elliptical mask with a cuff. The cuff can either be an inflating type (achieved after insertion using a syringe of air), or self-sealing. [citation needed] A laryngeal mask airway must first be completely sterilised (it may be reused many times). [1]
There are many methods of subcategorizing this family of devices including route of insertion, absence or presence of a cuff, and anatomic location of the device's distal end. The most commonly used devices are laryngeal masks and supraglottic tubes, such as oropharyngeal (OPA) and nasopharyngeal airways (NPA). [17]
laryngeal mask airway, laryngeal tube [ edit on Wikidata ] 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. [ 1 ]
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent (open and unobstructed) airway. Tracheal tubes are frequently used for airway management in the settings of general anesthesia, critical care, mechanical ventilation, and emergency medicine. Many different types of ...
Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation, and the balloon tamponade with a Sengstaken–Blakemore tube (a tube into the gastrointestinal tract). [1]
The purpose of ventilation with 100% oxygen is to denitrogenate healthy patients and prolong the safe apneic time. Tubes with an internal diameter of over 8mm are acceptable for most adults. Insertion technique includes visualizing the epiglottis, the posterior laryngeal structure, and not passing the tube unless tracheal insertion is ensured. [24]
