Your Child's Nasogastric Tube: Flushing the Tube

Your child is going home with a nasogastric (NG) feeding tube in place. This is a soft, thin tube put in through your child’s nose that goes down into the stomach. It sends liquid food directly to the stomach. You’ll need to flush your child’s tube regularly to keep it from getting clogged. You were shown how to do this before your child left the hospital. This sheet will help you remember those steps at home. If you need more help, talk with the hospital staff. They can tell you how to arrange for a home health nurse to help you.

Keep in mind that there are many types of NG tubes and syringes. Your child’s NG tube and supplies may look or work differently than those shown here. One type of tube has a connection that lets you plug or push the syringe into the NG tube port. Another type has a twist-on safety connector. The twist-on safety connector means you must use a certain type of syringe. This twists onto your child's NG tube port. Follow your child's care team's directions for your child's NG tube.

Note

Take care to keep the feeding tube from becoming a strangulation risk to your child. Follow your healthcare team's advice on how to secure the tube safely.

Flushing the tube for bolus feeding using a syringe

Flush your child’s NG tube after each feeding, or as directed by your child’s healthcare provider or home health nurse.

The supplies you'll need are:

• Feeding syringe

• Water

Follow these steps:

• Wash your hands with soap and clean, running water for at least 20 seconds. Dry them with a clean towel.

• Make sure the feeding syringe is connected to the NG tube.

• Pour water into the syringe. If there is a clamp on the tubing, make sure it is open. Let the water run through the NG tube by gravity.

• If the water flows too slowly or doesn’t flow at all, place the plunger in the syringe. Gently push the plunger a small amount. This can help remove anything that is blocking or clogging the NG tube. Don't push hard. And don't push the plunger all the way into the syringe. Changing your child’s position so that they are lying down or sitting upright may also improve the flow.

• If there is a clamp on the tubing, close it once all the water has flowed through the tube.

• Disconnect the syringe from the NG tube when the flushing is done.

• Close the feeding port cap of the NG tube.

Flushing the tube for bolus feeding or continuous feeding using a pump

Flush your child’s NG tube after each bolus feeding, or as directed by your child’s healthcare provider or home health nurse. With continuous feeding, you may only need to flush the tube after the last daily feeding. Follow your child's healthcare team's specific instructions.

The supplies you’ll need are:

• 5 ml (cc) syringe

• Water

Follow these steps:

• Wash your hands with soap and clean, running water for at least 20 seconds. Dry them with a clean towel.

• Make sure the pump is in the STOP/OFF mode.

• Not all tubes have clamps. If the tubing has a clamp, make sure the clamp on the feeding bag tubing is closed.

• Disconnect the feeding bag tubing from the NG tube.

• Put the tip of the empty syringe in water.

• Draw up  1 to 5 ml (cc) of water. Follow your child's healthcare provider's instructions on how much water to use. The amount will vary by your child's age, needs, and situation.

• Connect the syringe to the feeding port of the NG tube. Depending on the type of NG port your child has, you may plug in the syringe or twist it on. If the NG tube has a clamp make sure it is open.

• Gently push the plunger all the way into the syringe. If there is a clamp on the NG tube, close it once all the water has been pushed out of the syringe.

• Disconnect the syringe from the NG tube when the flushing is done.

• Close the feeding port cap of the NG tube.
