In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for airway support is anticipated.
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 ...
Other tubes (such as the Bivona Fome-Cuf tube) are designed specifically for use in laser surgery in and around the airway. Various types of double-lumen endotracheal (actually, endobronchial) tubes have been developed (Carlens, [ 6 ] White, Robertshaw, etc.) for ventilating each lung independently—this is useful during pulmonary and other ...
Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body.Most commonly, intubation refers to tracheal intubation, a procedure during which an endotracheal tube is inserted into the trachea to support patient ventilation.
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation.The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it.
The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
Another important contribution by Macewen to modern surgery was the technique of endotracheal anaesthesia with the help of orotracheal intubation, which he described in 1880, and still in use today. Macewen was noted for his early and creative use of photographs for documenting patients' cases and for teaching surgery and medicine.
While Mallampati classes I and II are associated with relatively easy intubation, classes III and IV are associated with increased difficulty. A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult ...
