What will the nurse need before inserting a patients nasogastric tube?

A nasogastric tube enables a nutritionally adequate diet to be delivered directly to the stomach bypassing the oral route. It is the most common route for enteral feeding and nurses play a central role in caring for patients with a nasogastric tube. This article outlines the care required for an adult patient with a fine bore nasogastric tube.

) is often required for patients who have difficulty swallowing. This allows them to receive the necessary nutrients in a safe way. First time caregivers in particular, may find feeding tube management challenging.

At Jaga-Me, we believe in empowering caregivers to care for their loved ones. In this article, we will be sharing tips from Jaga-Me nurses on performing tube feeding care at home. If you still do not feel confident, our expert nurses can also perform feeding tube insertion services at home.

How often should I change the feeding tube? 

 Material of feeding tubeChange tube every:*Short-term (less than 3 weeks)Plastic7 daysLong-term (more than 3 weeks)Silicone e.g. Corflo, Kangaroo4 to 6 weeks

*Do check the manufacturer’s note for exact recommendations.

Hygiene should always be a top priority when performing feeding tube care at home. Syringes should be washed with water (do not boil) and thoroughly dried after each use. They should be changed every 2-3 days, and more frequently if there are visible marks in the syringe.

Tube Feeding Checklist

  1. Check that the micropore securing the tube is intact and has not shifted.
  2. Measure the exposed length of the tube. It should be the same as the exposed length when the feeding tube was first inserted. Some tubes have numeric markings for reference.
  3. Check the pH of the gastric content (aspirate).
    • Using an alcohol swab, clean the exterior of the spigot (cover of the exposed end of the feeding tube).
    • While kinking the tube, remove the spigot and clean the opening of the tube with an alcohol swab.
    • Insert the syringe (with plunger) into the opening of the tube. Release the kink.
    • Pull the plunger back gently till some gastric content is seen (usually colorless or green-yellow color).
    • If no gastric content can be seen, lean the patient to the left. Wait for 5 minutes and reattempt to collect gastric content. If there is no gastric content again, pump 10ml of air and try again. If there is still no gastric content, put 10ml of cool boiled water into the syringe and through the feeding tube. Wait for 5 minutes and attempt again. If this last attempt is unsuccessful, contact your home care nurse.
    • Observe the gastric content. The color should be colorless or yellow-green with some mucus strands. Semi-digested milk curds can be seen as well.
    • Pour the gastric content over a pH paper and compare the result to a pH chart. It should be between pH 1-6. *check the recommended pH range with your doctor, as your loved one may be taking some medication that could affect the pH of his gastric content*
    • You may feed your loved one if the pH is between 1-6 and the appearance of the gastric content is normal.

Frequently Asked Questions about Feeding Tube Care at Home

How do I check if the tube is still in place?

You can measure the exposed length of the feeding tube, and check that the micropore tape has not shifted.

What should I do if the tube has been displaced?

We recommend a trained nurse to assess the situation in person. Do not attempt to re-insert the feeding tube on your own.

How do I maintain the oral and nasal hygiene of the patient?

Carrying out feeding tube care at home doesn’t just involve changing and handling the tube. It also means maintaining your loved one’s oral and nasal hygiene to avoid debris, liquid, or plaque build up that can lead to health issues.

  • If your loved one is able to brush their teeth, allow them to do so twice a day
  • If they are unable to brush their teeth, use a toothette to clean the gums, teeth and tongue. Dip the toothette with sodium bicarbonate or oral gargle solution.
  • Using a damp cotton bud, gently clean the exterior of the nose with the feeding tube.

How often should I replace the micropore tape?

The micropore tape should be replaced once a day, when cleaning your loved one’s face. Using a warm cloth, gently loosen the micropore tape. Remove the tape from the face and from the tube. Reattach a new micropore tape.

Why is the milk not flowing down during the feeding?

It is most likely that the tube is stuck with milk or medicine. You may reposition your loved one to the left and observe if the milk flows. If it does not, contact your home care nurse for replacement of the feeding tube. Do not use the syringe and plunger to attempt to force through the obstruction as you could cause significant discomfort to your loved one.

What is needed for NG tube insertion?

Equipment needed for placement of NG tubes:.
Nasogastric tube: 16-18 French..
Cup of water with straw..
pH indicator..
Gloves..
Emesis basin..
Benzocaine spray (optional).
Water-based lubricant (optional).

What should be assessed before inserting NG tube?

Always assess correct placement of the NG tube prior to infusing any fluids or tube feeds as per agency policy. Check location of external markings on the tube and colour of the PH of fluid aspirated from the tube. Routine evaluation will ensure the correct placement of the tube and reduce the risk of aspiration.
