Discharge Instructions: Checking Placement of Nasogastric (NG) Feeding Tube

You are going home with a nasogastric (NG) feeding tube in place. An NG tube is a long, thin, flexible tube inserted through the nose into your stomach. A nasoenteric tube is passed into the small intestine. You will need to check the tube regularly to make sure the tip of the tube stays in your stomach. You were shown how to care for your tube in the hospital. These tubes are used short-term, especially in adults. Tubes are put directly into the stomach. Or they are put into the small intestine if longer access is needed. Examples are a G tube, PEG tube, or PEJ tube. This sheet helps you remember how to care for your tube when you are at home. Keep the phone number of your doctor or caregiver handy in case you have any questions or problems.

• Gather your supplies:
  • Permanent marker pen or a small piece of tape
  • Clear dressing or tape to hold the tube to your face after it is put in
  • Measuring tape or ruler
  • 50 mL syringe for use in flushing the tube and possibly for feedings
• Wash your hands with soap and with clean, running water for at least 20 seconds before and after you touch the tube.
• Check placement of your tube once every day.
• Look for the mark or tape on your tube at the place where it comes out of your nose. If there is no mark, make one.
• Look to see that the mark or tape you made on the tube is still in the same place each time you check placement.
• Keep the outside tubing above the level of your stomach to prevent backflow of fluids through the tube.
• Flush the tube with warm water before and after feedings or medicines to keep it from getting clogged. Flush the tube as directed by your doctor or nurse to help prevent clogging.
• Change the tape that fixes the outside tubing to your nose or cheek every day and whenever it gets dirty or wet.
• Look for any redness, swelling, or ulceration at the site where the tube enters your nose.
• Measure the length of the tube from your nose (nasal tube) to the end of the tube. If it's not the same length as it was the day before, your tube may not be in the right place.
