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

Home care

• Gather your supplies:

  • Permanent marker pen

  • Measuring tape or ruler

  • 50 mL syringe for use in flushing the tube and possibly for feedings 

• Wash your hands with soap and water before and after you touch the tube.

• Check placement of your tube once every day.

• Look for the mark 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 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 before and after feedings or medicines.

• 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.
