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]
Tubes constructed of silicone rubber, wire-reinforced silicone rubber or stainless steel are also available for special applications. For human use, tubes range in size from 2 to 10.5 mm (0.1 to 0.4 in) in internal diameter. The size is chosen based on the patient's body size, with the smaller sizes being used for infants and children.
The size is chosen based on the patient's body size, with the smaller sizes being used for pediatric and neonatal patients. Tubes larger than 6 mm ID usually have an inflatable cuff. Originally made from red rubber , most modern tubes are made from polyvinyl chloride.
A man with a nasogastric tube allowing food and medicine to be delivered through the nose and straight to the stomach. Enteral administration may be divided into three different categories, depending on the entrance point into the GI tract: oral (by mouth), gastric (through the stomach), and rectal (from the rectum).
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.
There are six sizes of the laryngeal tube, ranging from newborn (size 0) to large adult (size 5). The connector of the tube is color-coded for each size. The different sizes are calibrated according to weight or height. [2] The laryngeal tube was licensed for use during cardiopulmonary resuscitation in Japan in 2002, [2] and approved for use in ...
Gastric lavage, also commonly called stomach pumping or gastric irrigation, is the process of cleaning out the contents of the stomach using a tube. Since its first recorded use in the early 19th century, it has become one of the most routine means of eliminating poisons from the stomach. [1]
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.
