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.
After apnea created by RSI the same high flow nasal cannula will help maintain oxygen saturation during efforts securing the tube (oral intubation). [31] [32] The use of nasal oxygen during pre-oxygenation and continued during apnea can prevent hypoxia before and during intubation, even in extreme clinical cases. [33]
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 ).
Muscle relaxation allows surgery within major body cavities, such as the abdomen and thorax, without the need for very deep anaesthesia, and also facilitates endotracheal intubation. Acetylcholine , a natural neurotransmitter found at the neuromuscular junction , causes muscles to contract when it is released from nerve endings.
Nasogastric intubation is a medical process involving the insertion of a plastic tube (nasogastric tube or NG tube) through the nose, down the esophagus, and down into the stomach. Orogastric intubation is a similar process involving the insertion of a plastic tube (orogastric tube) through the mouth. [1] Abraham Louis Levin invented the NG tube.
Limitations of extraglottic devices arise in morbidly obese patients, lengthy surgical procedures, surgery involving the airways, laparoscopic procedures and others due to its bulkier design and inferior ability to prevent aspiration. [29] In these circumstances, endotracheal intubation is generally preferred.
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 20th century saw the transformation of the practices of tracheotomy, endoscopy and non-surgical tracheal intubation from rarely employed procedures to essential components of the practices of anesthesia, critical care medicine, emergency medicine, gastroenterology, pulmonology and surgery.
