Double-lumen Endotracheal Tube
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 lung. Indications There are several conditions that may make one-sided lung ventilation necessary. Absolute indications include separation of the right from the left lung to avoid spillage of blood or pus from an infected or bleeding side to the unaffected side. Relative indications include the collapse of one lung and the selective ventilation of the remaining lung in order to facilitate exposure of the anatomical structures to be operated on in thoracic surgeries, such as the repair of a thoracic aortic aneurysm, pneumonectomy or lobectomy.Miller, Ronald.D, Anesthesia, Fifth edition Section 4: Subspecialty Management, Chapter 48:Anesthesia for Thoracic Surgery, published by Churchill Livingstone (200 ...

Thoracic Surgery
Cardiothoracic surgery is the field of medicine involved in surgical treatment of organs inside the thoracic cavity — generally treatment of conditions of the heart (heart disease), lungs (lung disease), and other pleural or mediastinal structures. In most countries, cardiothoracic surgery is further subspecialized into cardiac surgery (involving the heart and the great vessels) and thoracic surgery (involving the lungs, esophagus, thymus, etc.); the exceptions are the United States, Australia, New Zealand, the United Kingdom, and some European Union countries such as Portugal. Training A cardiac surgery residency typically comprises anywhere from four to six years (or longer) of training to become a fully qualified surgeon. Cardiac surgery training may be combined with thoracic surgery and / or vascular surgery and called cardiovascular (CV) / cardiothoracic (CT) / cardiovascular thoracic (CVT) surgery. Cardiac surgeons may enter a cardiac surgery residency directly from me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airtraq
Airtraq is a fibreoptic intubation device used for indirect (video or optic assisted) tracheal intubation in difficult airway situations. It is designed to enable a view of the glottic opening without aligning the oral with the pharyngeal, and laryngeal axes as an advantage over direct endotracheal intubation and allows for intubation with minimal head manipulation and positioning.D. Gravenstein, S. LampotangAIRTRAQ Laryngoscope''University of Florida Department of Anesthesiology'', 2 July 2011, retrieved 2 July 2013 Description Airtraq was developed by Pedra A. Gandarias and produced and marketed by Prodol Meditec S.A., Vizcaya, Spain. The standard Airtraq is a disposable article with an eyepiece optic, while the AirtraqAvant allows re-use of the optical system as well as external video monitoring and recording. The Airtraq blade is anatomically formed, with a battery-powered light source at the tip of the blade. The battery power reserve is sufficient to power the bulb fo ...

Endotracheal Tube
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent airway and to ensure the adequate exchange of oxygen and carbon dioxide. Many different types of tracheal tubes are available, suited for different specific applications: * An endotracheal tube is a specific type of tracheal tube that is nearly always inserted through the mouth (orotracheal) or nose (nasotracheal). * A tracheostomy tube is another type of tracheal tube; this curved metal or plastic tube may be inserted into a tracheostomy stoma (following a tracheotomy) to maintain a patent lumen. * A tracheal button is a rigid plastic cannula about 1 inch in length that can be placed into the tracheostomy after removal of a tracheostomy tube to maintain patency of the lumen. History Portex Medical (England and France) produced the first cuff-less plastic 'Ivory' endotracheal tubes. Ivan Magill later added a cuff (these were glued on by hand to mak ...

Combitube
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.Jorge E. Zamora and Tarit K. Saha,Combitube rescue for cesarean delivery followed by ninth and twelfth cranial nerve dysfunction Canadian Journal of Anesthesia Volume 55, Issue 11 , pp 779-784, published 2008 It is designed to provide an airway to facilitate the mechanical ventilation of a patient in respiratory distress. Description and use It consists of a cuffed, double-lumen tube that is inserted through the patient's mouth to secure an airway and enable ventilation. Generally, the distal tube (tube two, clear) enters the esophagus, where the cuff is inflated and ventilation is provided through the proximal tube (tube one, blue) which opens at the level of the larynx. In the rare instance where the distal tube intubates the trachea, ventilation is provided through the distal tube. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endobronchial Blocker
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. The lung tissue distal to the obstruction will collapse, thus allowing the surgeon's view and access to relevant structures within the thoracic cavity. Bronchial blockers are used to achieve lung separation and one lung ventilation as an alternative to double-lumen endotrachealtubes (DLT) and are the method of choice in children and paediatric patients for whom even the smallest DLTs might be too big. Types Univent tube Made by Fuji Systems, Tokyo, Japan, is a tracheal tube with a second lumen that contains a coaxial, balloon tipped catheter which can be advanced under fiber optic bronchoscopy and blocked in either bronchus.

Bronchoscope
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy. This allows the practitioner to examine the patient's airways for abnormalities such as foreign bodies, bleeding, tumors, or inflammation. Specimens may be taken from inside the lungs. The construction of bronchoscopes ranges from rigid metal tubes with attached lighting devices to flexible optical fiber instruments with realtime video equipment. History The German laryngologist Gustav Killian is attributed with performing the first bronchoscopy in 1897. Killian used a rigid bronchoscope to remove a pork bone. The procedure was done in an awake patient using topical cocaine as a local anesthetic. From this time until the 1970s, rigid bronchoscopes were used exclusively. Chevalier Jackson, refined the rigid bronchoscope in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coaxial
In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable is a three-dimensional linear structure. It has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (wings) mounted one above the other on concentric shafts, with the same axis of rotation (but turning in opposite directions). In loudspeaker design, coaxial speakers A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate s ...

Thoracic Cavity
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum. There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and a lower inferior thoracic aperture known as the thoracic outlet. The thoracic cavity includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck. Structure Structures within the thoracic cavity include: * structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein * structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs * structures of the digestive system, including ...
