The Challenge of Clogged Feeding Tubes

Feeding tube blockages are a common clinical issue, affecting up to 25% of patients receiving long-term enteral nutrition. Blockages may be caused by:

• Improper flushing technique
• Medication sediment or formula residue
• Kinked tubing or narrow lumens
• Bacterial biofilm buildup

When left unresolved, a blocked tube can:

• Interrupt vital nutrient and medication delivery
• Lead to unnecessary tube replacements
• Increase hospital costs and patient stress

This is where gastric valve declogging systems like the Avanos Clog Zapper play a vital role—restoring patency quickly and non-surgically.

What Is the Avanos Clog Zapper?

The Avanos Clog Zapper Enteral Feeding Tube Declogging System is a pre-mixed, clinically tested solution that:

• Breaks down formula clogs and medication buildup
• Works with most enteral feeding tubes, including NG, PEG, GJ, and low-profile devices
• Contains digestive enzymes such as papain and cellulase for effective tube cleansing
• Is delivered via a proprietary applicator tip compatible with ENFit and legacy connectors

The Clog Zapper kit includes:

• Enzyme packet or pre-filled applicator
• Instructions for clinical or home use
• Applicator syringe or delivery tool (based on model)

Its design reduces the risk of unnecessary procedures by allowing on-the-spot declogging, which is particularly valuable in remote or home care settings.

Clinical Applications and Benefits

The Avanos Clog Zapper is an essential product for:

• Hospital wards: Reduces delays in feeding schedules
• Aged care facilities: Prevents unnecessary tube replacements
• Home care settings: Enables non-clinicians to manage clogs safely
• Emergency response kits: Offers fast, effective intervention for enteral blockages

Clinical benefits include:

• Decreased risk of infection from unnecessary tube changes
• Improved feeding continuity
• Reduced costs associated with interventional tube replacement
• Increased confidence in caregivers managing enteral nutrition

A study published in JPEN Journal of Parenteral and Enteral Nutrition found that enzyme-based declogging methods were successful in 81% of occluded feeding tubes without requiring endoscopic intervention.

How It Works: A Closer Look at the Declogging Process

The Avanos Clog Zapper is activated upon administration and works by enzymatically degrading the material causing the clog. Here's a step-by-step look at the standard application process:

1. Check tube placement and confirm clog (e.g. inability to flush or aspirate).
2. Prepare and apply Clog Zapper using the provided applicator.
3. Allow 30–60 minutes of dwell time for enzymes to break down debris.
4. Flush tube with warm water to restore patency.
5. Repeat process if necessary, up to 2–3 times.

Key advantages:

• Safe for paediatric and adult patients
• No need for guidewire or surgical intervention
• ENFit-compatible for modern enteral systems
• Highly portable for bedside or home use

In most cases, one application is sufficient to clear blockages. Always consult a clinician for guidance on repeated use or resistant blockages.

Best Practices for Preventing Future Clogs

While the Clog Zapper is a powerful tool, prevention remains the best defence. Incorporate these best practices into routine care:

• Flush before and after feeds using sterile water
• Use liquid medications whenever possible; crush only with approval
• Avoid mixing medications with formula
• Flush between medications to reduce residue buildup
• Inspect tubing daily for kinks, signs of pressure, or slow flow

When paired with good prevention habits, a gastric valve declogging system helps extend tube life and maintain uninterrupted feeding schedules.
