Ryle's Tube


Ryle’s Tube is a thin flexible tube of rubber or plastic which is inserted into the stomach through the mouth or nose of a patient and is used for withdrawing fluid from the stomach or for giving a test meal.

Ryle’s Tube or (NG – Nasogastric Tube)

Nasogastric intubation is a medical process involving the insertion of a plastic tube (Nasogastric Tube, NG Tube) through the nose, past the throat and down into the stomach.

Did you know?  Ryle’s Tube was designed by J.A. Ryle, A British Physician (1889-1950)

What is a “Nasogastric” Tube OR Ryle’s Tube?
A Nasogastric tube is a narrow bore tube passed into the stomach via the nose. It is used for the short or medium term nutritional support and also for aspiration of stomach contents. Example: for decompression of intestinal obstruction.
The use of Nasogastric or Ryle’s Tube is suitable for enteral feeding for up to six weeks. Polyurethane or Silicone feeding tubes are unaffected by gastric acid and can therefore remain in the stomach for a longer period than PVC Tubes.

What is Enteral Feeding?
Enteral Feeding refers to the delivery of a nutritionally complete feed containing protein, carbohydrate, fat, water, minerals and vitamins directly into the stomach, duodenum or jejunum.
Who uses Ryle’s Tube?
Nasogastric Tubes or NG Tubes or Ryle’s Tube is used at all Hospitals.

  • Explain the procedure and obtain consent
  • Provide a signal for the patient to stop the procedure
  • Sit the patient in a semi-upright position with the head supported with pillows and tilted neither backwards nor forwards

  • Measure the tubing from the bridge of the nose to the earlobe, then to the point halfway between the lower end of the sternum and the navel
  • Mark the measured length with a marker or note the distance
  • Lubricate 2-4 inches of tube with lubricant (e.g. 2% Xylocaine®)
  • Pass the tube via either nostril, past the pharynx, into the esophagus and then into the stomach
