AMBULATORY CARE:
A nasogastric (NG) tube
is a long, thin, flexible tube inserted through your nose and down into your stomach or small intestine. You may be sent home with the tube in place in order to get the nutrition you need. Your tube will be removed by your healthcare provider when it is no longer needed.
What will happen during the procedure:
- You will be asked to sit up. A healthcare provider will measure the length of the tube needed to reach your stomach.
- The NG tube will be inserted into your nose, down your throat, and into your stomach. You will need to swallow several times and tilt your head forward to help the tube go down.
- The tube will be taped to your nose or cheek to keep it in place. Your healthcare provider will check for proper placement of the tube.
- You may need an x-ray to confirm placement of the tube.
What to expect after the procedure:
- A suction device or feeding pump may be connected to the end of the NG tube.
- Healthcare providers will check on the tube regularly to make sure it stays in place.
- The tube can stay in place for up to 8 weeks. You may be sent home with the tube in place in order to get the nutrition you need.
Risks of an NG tube:
You may develop a dry mouth or a nose infection. The NG tube may enter the wrong place, such as your lungs, and cause breathing problems. The tube placement may cause bleeding, an infection, or an injury. The tube may move out of place.
Call your local emergency number (911 in the US) if:
- You suddenly start coughing and become short of breath.
Seek care immediately if:
- You are vomiting.
- Your tube comes out.
Call your doctor if:
- You have redness or a sore where the tube enters your nose.
- You have heartburn.
- You have a fever.
- Your tube is blocked and does not open with flushing.
- You have stomach pain or bloating.
- You have questions or concerns about your condition or care.
NG tube care:
- Wash your hands before and after touching the tube. You may be directed to wear gloves. This will help keep bacteria away from your tube.
- Keep the outside tubing above the level of your stomach. This will help prevent fluid from backing up into your NG tube. Make sure the tube is pinned to your clothes. This helps prevent discomfort and pulling on the tube.
- The tape that attaches the NG tube to your nose or cheek may need to be changed every day. The tape will also need to be changed if it gets wet or dirty. You will need to check the skin on your nose for any inflammation.
- Placement of the tube will need to be checked several times during the day. Healthcare providers will teach you how to remove and test stomach fluid to confirm placement.
- Your NG tube will need to be flushed before and after feedings or medicines are put in the tube. Your NG tube may also need to be flushed if the tube becomes blocked. Follow your healthcare provider's instructions on how to flush your tube.
