An NG (nasogastric) tube is one that is passed through the nose (via the nasopharynx and esophagus) down into the stomach.
An NG tube is a flexible tube made of rubber or plastic and has bidirectional potential. A nasogastric tube can thus be used to remove the contents of the stomach including air (to decompress the stomach) and small solid objects and fluid (e.g., to evacuate poison from the stomach). A nasogastric tube can also be used to instill liquids into the stomach (e.g., to feed the person).
The word “nasogastric” is a hybrid — part Latin, part Greek. “Naso-” is a prefix that has to do with the nose and comes from the Latin “nasus” for nose or snout. “Gastric” comes from the Greek “gaster” meaning the paunch or belly. The term “nasogastric” was coined in 1942.
- Tube, otopharyngeal
the upper part called the nasopharynx, the middle part called the oropharynx, and the lower part called the hypopharynx. The Eustachian tube opens into the nasopharynx. The Eustachian tube measures only 17-18mm and is horizontal at birth. As it grows to double that length, it grows to be at an incline of 45 degrees in […]
- Tube, tympanostomy
A small tube inserted into the eardrum to keep the middle ear aerated for a prolonged period of time. These ventilating tubes usually remain in place for 6 months to several years. Eventually, they move out of the eardrum (extrude) and fall out into the ear canal. Also called ear tubes.
A lump or bump. For example, the backward protrusion of the heel is called the tuber calcanei or, alternatively, the tuberosity of the calcaneus. Small tubers are a characteristic finding in tuberculosis, and tubers in the brain are seen in tuberous sclerosis.
A small tuber; a small lump or bump.
A protein extracted from Mycobacterium tuberculosis that is used in a skin test to determine if a person has been exposed to tuberculosis. The tuberculin preparation in most common use today is purified protein derivative (PPD) tuberculin. PPD is injected (or multiple-punctured) into the skin. If a reaction is seen at and around the site […]
