According to the American Society for Parenteral and Enteral Nutrition (ASPEN), flushing a feeding tube with warm water is the best first-line defense against occlusions. This guide will explain exactly what you can use to clean a feeding tube, its accessories, and the insertion site safely and effectively.

Quick Summary

This guide details the proper supplies and techniques for cleaning feeding tubes and their components, including warm water, mild soap, and specific declogging solutions. It covers daily flushing, weekly deep cleaning, and how to safely manage clogs and site care.

Key Points

Warm Water is Key: Use lukewarm water for daily flushing before and after all feedings and medications to prevent most clogs.
Clean the Site Daily: Wash the skin around the feeding tube insertion site daily with mild soap and water, then pat it dry to prevent infection.
Sanitize Reusable Equipment: For reusable items like feeding bags and syringes, a 1:3 vinegar and water solution can be used weekly for sanitization.
Do Not Force a Clog: If a clog resists a gentle warm water flush, never use excessive force or unapproved liquids like soda, as this can damage the tube.
Consult a Professional: Always contact your healthcare provider for persistent clogs, signs of infection, or any other feeding tube-related concerns.
Inspect Equipment Regularly: Routinely check all components for signs of wear and tear, and follow recommended replacement schedules.

Why Proper Feeding Tube Hygiene is Crucial

Maintaining a clean feeding tube is essential for preventing complications like clogs and infections. Clogs can disrupt feeding schedules and lead to discomfort or improper nutrition, while infections can pose serious health risks. A consistent cleaning routine ensures the tube remains functional and safe for use. Both the tube's internal lumen and the external insertion site, known as the stoma, require specific care. Following healthcare provider instructions is always the primary rule of thumb.

Daily Flushing for Clog Prevention

Regular flushing is the most important step for maintaining a feeding tube's patency and is the primary answer to the question of what can you use to clean a feeding tube on a day-to-day basis.

Flushing Frequency:

Before and after every feeding.
Before and after administering any medication.
At least once per shift or every 4–8 hours for continuous feedings.
At least twice daily for tubes not in active use.

Flushing Technique with Warm Water:

Wash your hands thoroughly with soap and water.
Fill a 30 mL or 60 mL syringe with lukewarm water. Never use cold or hot water.
Clamp or pinch the feeding tube to prevent leakage.
Attach the syringe to the feeding port and unclamp the tube.
Gently push the water through the tube. Gravity can often assist.
Remove the syringe, reclamp the tube, and close the feeding port cap.

Daily Stoma Site Care

For abdominal feeding tubes (like G-tubes), daily care of the stoma site is vital to prevent skin irritation and infection.

Wash the area: Use a soft cloth or gauze with warm, mild, fragrance-free soap and water.
Clean under the bolster: Gently lift the external bolster to clean the skin underneath, using a cotton swab if necessary.
Rinse and dry: Rinse all soap residue with clear, warm water and pat the area completely dry with a clean towel.
Inspect the site: Check for signs of infection, such as redness, swelling, or unusual discharge.
Rotate the tube: If your healthcare provider has approved it, gently rotate the tube 360 degrees to prevent adhesion. Do not rotate jejunal or gastro-jejunal tubes unless directed.

Weekly Deep Cleaning for Reusable Equipment

For equipment like extension sets, syringes, and feeding bags, a weekly or bi-weekly deep cleaning is recommended in addition to daily rinsing.

Disassemble and wash: Separate all components. Hand wash everything with warm, soapy water. A tube brush or small scrub brush can be used to clean inside ports and the lumens of tubing.
Sanitize: For a weekly sanitizing step, a solution of 1 part white vinegar to 3 parts water can be used. Soak the equipment for 30 minutes.
Rinse thoroughly: Rinse all parts completely with clear water to remove any soap or vinegar residue.
Air dry: Allow all parts to air dry completely on a clean surface or towel.

Troubleshooting a Clogged Feeding Tube

If a clog occurs, do not panic. Always try the least invasive method first and consult your healthcare team if it persists.

Use Warm Water First: The initial step to address a clog is a gentle flush with warm water using a 60 mL syringe. Gently push and pull the syringe plunger to create movement. Let the water sit for 5-20 minutes to dissolve the blockage before trying again.
Enzymatic Declogger: If warm water is ineffective, an enzymatic declogging kit (e.g., Clog Zapper) or a solution of pancreatic enzymes can be used. Your healthcare provider will need to prescribe this.
Mechanical Devices: In some clinical settings, devices like the TubeClear® system can be used by professionals to clear stubborn clogs. These are not for home use.

Warning: Never use soda, juices, or any other unapproved liquids to clear a tube, as these can worsen the clog. Never insert any wires or objects into the tube.
