A Carlens double-lumen endotracheal tube, commonly used for thoracic surgical operations such as VATS lobectomy.. A double-lumen endotracheal tube (also called double-lumen endobronchial tube or DLT) is a type of endotracheal tube which is used in tracheal intubation during thoracic surgery and other medical conditions to achieve selective, one-sided ventilation of either the right or the left ...
Types of endotracheal tubes include oral or nasal, cuffed or uncuffed, preformed (e.g. RAE (Ring, Adair, and Elwyn) tube), reinforced tubes, and double-lumen endobronchial tubes. For human use, tubes range in size from 2 to 10.5 mm in internal diameter (ID).
There are a number of different types of double-lumen endo-bronchial tubes that have endobronchial as well as endotracheal channels (Carlens, White and Robertshaw tubes). These tubes are typically coaxial, with two separate channels and two separate openings. They incorporate an endotracheal lumen which terminates in the trachea and an ...
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] It is designed to provide an airway to facilitate the mechanical ventilation of a patient in respiratory distress .
An bronchial blocker (also called endobronchial blocker) is a device which can be inserted down a tracheal tube after tracheal intubation so as to block off the right or left main bronchus of the lungs in order to be able to achieve a controlled one sided ventilation of the lungs in thoracic surgery.
Nasopharyngeal airway in packaging Nasopharyngeal airways (NPA) are rubber tubes with a flange at one end. When properly used and with the correct size it allows for air to flow between the nose into the lungs. To use choose the appropriate size. Use a water-based lubrication gel to coat the outside of the NPA and the selected nostril.
It was a prolonged and distressing procedure. The technique was thought to be imperfect and therefore denounced by many physicians at that time. In 1964, Ramirez-Rivera used a double lumen endotracheal tube (DLT) to isolate each lung, instilling up to 3 L saline containing heparin or acetylcysteine. This trial provided evidence that such a ...
Compared to a cuffed tracheal tube, extraglottic devices provide less protection against aspiration but are more easily inserted and causes less laryngeal trauma. [27] Limitations of extraglottic devices arise in morbidly obese patients, lengthy surgical procedures, surgery involving the airways, laparoscopic procedures and others due to its ...
