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]
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 50–75-millimetre-long (2.0–3.0 in) curved metal or plastic tube may be inserted into a tracheostomy stoma (following a tracheotomy ) to ...
A cuffed endotracheal tube, constructed of polyvinyl chloride A Carlens double-lumen endotracheal tube, used for thoracic surgical operations such as VATS lobectomy. 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.
a flexible device introduced through the mouth during some intubation procedures; if the stylet is in the trachea, while passing in, gives a sensation of bumps and then finally stops going in at a point, it indicates that it was gliding over tracheal rings and has stopped at one of the bronchi (the patient may even cough during this time); if ...
In its basic (standard) version, the laryngeal tube is made up of a tube with a larger balloon cuff in the middle (oropharyngeal cuff) and a smaller balloon cuff at the end (oesophageal cuff). The tube is kinked at an angle of 30-45° in the middle; the kink is located in the larger cuff.
In these circumstances, endotracheal intubation is generally preferred. The most commonly used extraglottic device is the laryngeal mask airway (LMA). An LMA is a cuffed perilaryngeal sealer that is inserted into the mouth and set over the glottis. Once it is in its seated position, the cuff is inflated. [30]
Retroglottic airway devices (RGAs) pass behind the glottis and into the esophagus to create a seal allowing oxygen to be delivered directly to the trachea. [3] [5] The RGAs are designed as laryngeal tubes. [3] Examples of RGAs include the Combitube and the King LT. Studies comparing the effectiveness between the RGAs are lacking.
The Combitube's ease of use makes it an option for use in the pre-hospital, emergency setting when advanced level providers capable of placing an endotracheal tube are not immediately available. The drawbacks of Combitubes are evidenced by reports of serious complications such as aspiration, esophagus perforation [ 3 ] and cranial nerve ...
