Polyurethane NG tube (Viasys Corflo), 8 Fr × 36 in (91 cm). This fine bore tube is appropriate for longer use (up to 4 weeks). Types of nasogastric tubes include: Levin catheter, which is a single lumen, small bore NG tube. It is more appropriate for administration of medication or nutrition. [5]
Uncuffed tubes are also available, though their use is limited mostly to children (in small children, the cricoid cartilage is the narrowest portion of the airway and usually provides an adequate seal for mechanical ventilation). [13] In addition to cuffed or uncuffed, preformed endotracheal tubes are also available.
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 dozens of conditions that may require tube feeding (enteral nutrition) to prevent or treat malnutrition. Conditions that necessitate feeding tubes include prematurity, failure to thrive (or malnutrition), neurologic and neuromuscular disorders, inability to swallow, anatomical and post-surgical malformations of the mouth and esophagus, cancer, Sanfilippo syndrome, and digestive ...
The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. [10] The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. [5] The device is inserted until the flared end rests against the ...
The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
The tube may be difficult to position, particularly in an unwell patient, and may inadvertently be inserted in the trachea, hence endotracheal intubation before the procedure is strongly advised to secure the airway. The tube is often kept in the refrigerator in the hospital's emergency department, intensive care unit and gastroenterology ward.
Nasogastric tube (Levin type) Abraham Louis Levin (December 16, 1880 – September 15, 1940) was an American physician and the inventor of the Levin Tube, which is still widely used for duodenal drainage after surgery and for management of trauma patients. [1] This procedure is known as nasogastric intubation.
