About Tube Feeding

If you cannot eat sufficient quantities of food to meet nutritional needs, then feeding can be given through a tube into the stomach or small bowel to provide adequate nutrients. There are a variety of tube feeding formulas on the market which are designed to meet 100% of your nutritional needs. The feedings may be given continuously over several hours, around the clock at a specific rate, and delivered by a special pump or several times a day in measured amounts. Adequate nutrition depends on the right type and amount of formula. Your healthcare provider will prescribe your feeding schedule, formula and amount of water needed for optimal nutrition and hydration.

After a brain or spinal cord injury, the metabolic rate may be increased and energy and protein needs may be high to provide nutrients for healing. Muscle atrophy is also common because of decreased mobility during this time. Calorie and protein needs tend to decrease a few months after injury, so tube feedings may need to be adjusted to avoid unwanted weight gain. It is important to monitor your body weight and know your weight goals. If you have significant weight changes (gain or loss of more than 2 lbs in 1 week) or if you are cleared to eat by a Speech Language Pathologist, contact your doctor, home health company, or registered dietitian for a tube feeding adjustment.

Types of Feeding Tubes

1. Percutaneous Endoscopic Gastrostomy (PEG) Tube is a tube that goes through the skin and directly into the stomach, used to administer tube feeding, water and medications.
2. Percutaneous Endoscopic Jejunostomy (PEJ) Tube is inserted in a similar manner as the PEG, but the tube is moved past the stomach into the top of the small intestine.
3. Nasogastric tube (NG) is a common type of feeding tube for short term use. It enters through the nose and its tip ends up in the stomach.

Tube Feeding Preparation

• Store the unopened products at room temperature, not in direct sunlight.
• Wash your hands prior to handling the products.
• Shake the can or bottle well and wipe the top clean prior to opening.
• Administer the feeding when the product is at room temperature.
• Cover any unused product and store in the refrigerator.
• Store the product for a maximum of 24 hours; if not used, discard the remainder.
• When administering the feeding product after it has been refrigerated, let the product warm to room temperature by setting it on the counter for about 15 minutes before putting it through the feeding tube. Never microwave any tube feeding product.

Supplies to Gather:

• Correct tube feeding to be delivered (can or 24 hour bottle)
• Feeding pump (if on continuous tube feeding)
• Feeding set (bag set or spike set)
• 60 ml syringe
• Graduated container
• 50 ml water

Positions for receiving tube feedings:

• Option 1: Propped up in bed or on a couch in a half sitting position with the head raised at least 30 degrees
• Option 2: Sitting up in a chair
• Never while lying flat

How to check gastric residual (PEG feedings only):

"Residual" refers to fluid/contents that remain in the stomach. Only those fed through a PEG tube should have a residual.

1. Connect a syringe to the PEG tube.
2. Gently draw back the plunger of the syringe to withdraw stomach contents.
3. Read the amount in the syringe.
4. Inject the contents back into the feeding tube (It contains important electrolytes and nutrients).
5. Use the syringe to rinse the feeding tube with 30 ml of water.
6. If the gastric residual is more than 200 ml, delay the feeding.
7. Wait 30 - 60 minutes and do the residual check again. If the residuals continue to be high (more than 200 ml) and feeding cannot be given, call your healthcare provider for instructions.

1. Wash hands.
2. Assess abdomen for distention.
3. Elevate head of bed to at least 30 degrees.
4. If using a PEG tube, measure residual every 4 hours (if residual is more than 200 ml or other specifically ordered amount, hold for one hour and recheck; if it still remains high, notify doctor).
5. If using a PEG tube, reinstall residual.
6. Hang tube feeding (no more than 8 hours' worth if in bag set up).p;
7. Prime tubing.
8. Connect tubing to client.
9. Set rate.
10. Start pump.

1. Wash hands.
2. Assess abdomen for distention.
3. Elevate head of bed to at least 30 degrees.
4. If using a PEG, measure residual every 4 hours (if residual is more than 200 ml or other specifically ordered amount, hold for one hour and recheck; if it still remains high notify doctor).
5. If using a PEG, reinstall residual.
6. Insert 60 ml syringe into port and pour feeding product into syringe.
7. Add formula to drain by gravity.
8. Add more formula until the desired amount is infused.
9. Flush with 50 ml (or amount ordered by doctor) of water.
10. Cap the tube.
11. Remain in upright position for at least one hour after feeding.
12. Rinse equipment thoroughly.

Note: If using a PEG, it is important to check tube feeding residuals every 4 hours while receiving continuous feedings and right before bolus feedings.

Cleaning the Tube Site and Equipment

• The site should be cleaned daily with soap and water.
• Do site care per the doctor's orders.
• Tube feeding bag sets (seen in the picture below) may be cleaned with soap and water.
• Make sure to run the soapy water through the tubing as well.
• Tube feeding bag sets are good as long as they remain intact.
• Rinse with water to make sure all of the soap is out of the bag and the tubing.
• Syringes and canisters may be cleaned with soap and water or placed in a dishwasher on the top rack. They may also be used for as long as they remain intact.

Mouth Care:

• Good mouth care is very important, even when you're not eating or drinking.
• Brush all the surfaces of your teeth, gums and tongue at least two times a day.
• Use a soft bristled electric toothbrush if your loved one is able to tolerate the vibration. Mild toothpaste or powder is recommended.
• Use alcohol free mouthwash or a mild salt solution (1/2 teaspoon of salt in 2 cups of water), as needed to freshen breath.
• If your lips are dry, use a lanolin-based moisturizing cream to moisten lips.
• Tell your doctor if the dryness does not go away. More fluids may need to be added through the tube.
• Tell your healthcare provider if you have bleeding gums or sores.

Troubleshooting Feeding Tubes

Recognition:

• Inability to flush with water
• Inability to administer tube feeding or medications

Causes:

• Inadequate flushing of tube
• Medications not adequately crushed and dissolved before being put in tube
• Tube clamp is closed
• Defective tubing
• Tube feeding infusion rate is too low

Prevention:

• Flush the tube with 5 ml water between each medication.
• To prevent tube blockage, flush the tube with 30-50 ml warm water:
  • Before and after each feeding
  • Every 4 hours if the patient is receiving continuous feedings
  • After checking for stomach content residuals
• Do not mix medication with formula.
• Medication should be in liquid form when possible. If not, crush finely and make sure it is well dispersed in water.
• Give multiple medications one at a time and rinse the tube with warm water before and after.
• Open clamp when flushing, feeding or administering medications.

What do I do when I have a clogged tube?

1. Draw up warm (never hot or cold) water with plunger into the syringe, attach to feeding tube and gently work it back and forth to loosen the clog.
2. Pull out as much of the contents of the tube as you can.
3. "Milk" or massage the tube to loosen the residual.
4. Contact your healthcare provider if the clog is not released easily.

Recognition:

• Nausea, vomiting
• Abdominal cramping, pain, feeling bloated

Causes:

1. Mechanical problem

• Tube displaced
• Patient not positioned properly
