Nasogastric feeding tube

Definition

A nasogastric tube (NG tube) is a special tube that carries food and medicine to the stomach through the nose. It can be used for all feedings or for giving a person extra calories.

You'll learn to take good care of the tubing and the skin around the nostrils so that the skin doesn't get irritated.

Follow any specific instructions your health care provider or nurse gives you. Use the information below as a reminder of what to do.

Alternative Names

Feeding - nasogastric tube; NG tube; Bolus feeding; Continuous pump feeding; Gavage tube

What to Expect at Home

If your child has an NG tube, try to keep your child from touching or pulling on the tube.

After your nurse teaches you how to flush the tube and perform skin care around the nose, set up a daily routine for these tasks.

Flushing the Tube

Flushing the tube helps release any formula stuck to the inside of the tube. Flush the tube after each feeding, or as often as your nurse recommends.

  • First, wash your hands well with soap and water.
  • After the feeding is finished, add warm water to the feeding syringe and let it flow by gravity.
  • If the water does not go through, try changing positions a bit or attach the plunger to the syringe, and gently push the plunger part-way. Do not press all the way down or press fast.
  • Remove the syringe.
  • Close the NG tube cap.

Taking Care of the Skin

Follow these general guidelines:

  • Clean the skin around the tube with warm water and a clean washcloth after each feeding. Remove any crust or secretions in the nose.
  • When removing a bandage or dressing from the nose, loosen it first with a bit of mineral oil or other lubricant. Then gently remove the bandage or dressing. Afterward, wash the mineral oil off the nose.
  • If you notice redness or irritation, try putting the tube in the other nostril, if your nurse taught you how to do this.

When to Call the Doctor

Contact your health care provider if any of the following occur:

  • There is redness, swelling and irritation in both nostrils
  • The tube keeps getting clogged and you are unable to unclog it with water
  • The tube falls out
  • Vomiting
  • Your stomach is bloated

Tube feeding
Tube feeding is a way to provide nutrition when you cannot eat or drink safely by mouth. This can happen if you are unconscious or have trouble swallowing. Besides nutrition, tube feeding can provide fluids and medicines. It can also be used to remove stomach contents. The types of tubes used include the nasogastric tube (NG tube), the gastrostomy tube (G-tube or PEG-tube), and the jejunostomy tube (J-tube or PEJ-tube). The NG tube is inserted through the nose and is used for a short time. The G-tube and J-tube are inserted through a small incision in the skin on the abdomen and are for longer-term use.
