Seven Tricks to Restore NGT Flow

This article serves as a practical guide, offering seven actionable tricks to help you tackle blocked NGTs. These techniques are designed to provide immediate solutions.

Our goal is to equip you with the confidence and knowledge to address this common issue. These tricks will help you manage the situation effectively, while always understanding the importance of seeking professional medical help when necessary.

Understanding NGT Blockages: Common Causes & Contributing Factors

As we’ve established, a blocked nasogastric tube can be a significant impediment to care. But why do these blockages occur in the first place? Understanding the root causes is essential not only for addressing existing blockages but also for preventing them in the future.

Common Obstruction Causes

Several factors can contribute to the obstruction of an NGT. Identifying these culprits is the first step in proactive management.

Thick Secretions and Mucus Build-Up

The human body naturally produces mucus and secretions. Within the confined space of the NGT, these fluids can thicken and accumulate, particularly if the patient is not adequately hydrated. This build-up can gradually narrow the tube’s lumen, eventually leading to a complete blockage.

Medication Interference

Medications, especially those administered in crushed pill form, are frequent offenders. If crushed pills are not fully dissolved before administration, they can clump together and solidify within the tube. Certain medications may also interact with each other or with gastric fluids, forming precipitates that contribute to blockages.

Kinked Tube

A physical kink in the NGT is a straightforward but common cause of obstruction. This can occur due to:

• Patient positioning: The tube might bend or crimp as the patient moves or lies in certain positions.
• Improper insertion: If the tube wasn’t inserted correctly initially, it could be prone to kinking.

Inadequate or Infrequent Flushing

Consistent flushing is crucial for maintaining NGT patency. When flushing is infrequent or inadequate, residues from feedings, medications, and secretions can accumulate, leading to gradual narrowing and eventual blockage.

The Role of Dehydration

Dehydration plays a significant role in the development of NGT blockages. When the body is dehydrated, secretions become thicker and more viscous. These thickened secretions are more likely to adhere to the inner walls of the NGT and contribute to blockages. Maintaining adequate hydration is paramount in preventing this issue. Ensure the patient receives sufficient fluids, whether orally or intravenously, as prescribed by their healthcare provider. Careful monitoring of hydration status is essential.

Trick 1: The Gentle Water Flush – A First Line of Defense

Having explored the common culprits behind NGT blockages, we can now turn our attention to practical solutions. One of the simplest, and often most effective, initial strategies is a gentle water flush.

This method serves as a primary intervention, and when performed correctly, it can resolve many common obstructions without requiring more aggressive measures. Safety and proper technique are paramount.

Preparing for the Flush: Water Selection and Hygiene

Before commencing the flush, ensure you have the correct type of water. Sterile water is generally preferred, especially for patients who are immunocompromised or have specific medical conditions. Distilled water is a suitable alternative if sterile water isn’t readily available.

Tap water should be avoided due to the potential for introducing contaminants. Also, gather all necessary supplies, including a clean syringe (typically 30-60 ml), and maintain strict hygiene practices to prevent infection.

Step-by-Step: Performing the Water Flush

1. Draw Water into the Syringe: Carefully draw the appropriate amount of water into the syringe. Ensure no air bubbles are present, as these can cause discomfort.

2. Connect the Syringe to the NGT: Disconnect any feeding or medication administration set from the NGT. Then, gently connect the syringe to the open end of the NGT.

3. Gentle Instillation: Slowly and steadily, instill the water into the NGT. Avoid forcing the fluid, as this could damage the tube or cause discomfort to the patient.

4. The "Push-Pull" Technique: After instilling a portion of the water (e.g., 5-10 ml), gently attempt to aspirate fluid back into the syringe. This "push-pull" motion can help dislodge the blockage by creating alternating pressure.

   Repeat this process several times, gradually instilling more water each time, while continuing to attempt aspiration.

5. Observe for Resistance: Pay close attention to any resistance you feel while flushing. If you encounter significant resistance, do not force the fluid. Move on to other troubleshooting techniques or seek professional assistance.

Determining the Appropriate Water Volume

The volume of water used for flushing depends on several factors, including the patient’s age, size, and medical condition. A general guideline is to use 30-60 ml for adults and smaller volumes for children.

Be mindful not to overfill the stomach, as this can lead to discomfort, vomiting, or aspiration. If you are unsure about the appropriate volume, consult with a healthcare professional.

Trick 2: Saline Solution Flush – When Water Isn’t Enough

Sometimes, despite our best efforts, a gentle water flush simply won’t cut it. More stubborn blockages, particularly those involving certain medications or dried secretions, may require a more assertive approach. That’s where saline solution comes into play.

The Power of Saline: Why It Works

Saline solution, specifically 0.9% NaCl (normal saline), is a sterile solution of sodium chloride in water. Its effectiveness stems from its ability to dissolve certain substances more readily than water alone.

Some medications, for example, are more soluble in saline, meaning it can break down and dislodge them from the tube’s inner walls more effectively. Saline can also help to loosen thick, sticky mucus, making it easier to flush out.

Sterile Technique is Crucial

When using saline solution, meticulous sterile technique is absolutely paramount. This is to prevent the introduction of harmful bacteria into the patient’s system, which could lead to serious infections.

Essential Steps for Sterile Saline Flush:

• Use Sterile Saline: Always use commercially prepared, sterile saline solution. Do not attempt to make your own.

• Sterile Syringe: Employ a sterile syringe for drawing up and administering the saline.

• Avoid Contamination: Be careful not to touch the tip of the syringe or the open end of the NGT to any non-sterile surfaces.

• Hand Hygiene: Wash your hands thoroughly with soap and water, or use an alcohol-based hand sanitizer, before and after the procedure.

Performing the Saline Flush

The process for performing a saline flush is very similar to that of a water flush:

1. Draw the appropriate amount of sterile saline solution into the sterile syringe.

2. Gently connect the syringe to the open end of the NGT, after disconnecting any feeding or medication administration sets.

3. Instill the saline slowly and steadily, avoiding forceful injections.

4. Employ the "push-pull" technique, gently attempting to aspirate fluid back into the syringe to help dislodge the blockage.

Always monitor the patient for any signs of discomfort or distress during the procedure. If resistance is met or the patient experiences pain, stop immediately and consult with a healthcare professional.

Trick 3: The Position Check – Identifying and Correcting Kinks

Sometimes, the simplest solutions are the most effective. Even with diligent flushing, a nasogastric tube can refuse to cooperate. Before reaching for more aggressive measures, take a moment to consider the possibility of a kink. A bend or twist in the tubing can easily obstruct the flow, mimicking a blockage caused by secretions or medication.

The Importance of Visual Inspection

The first step in addressing a potential kink is a thorough visual inspection of the NGT. Carefully examine the tube along its entire length, from the point where it exits the nose to where it connects to the feeding pump or suction device. Look for any sharp bends, twists, or compressions in the tubing. These are telltale signs of a kink.

Patient Positioning and Its Impact

Patient positioning plays a significant role in the formation of kinks. Certain positions, especially those involving bending or twisting of the torso, can put undue stress on the NGT, causing it to buckle. For instance, a patient lying on their side with the tube compressed between their body and the bed is highly susceptible to developing a kink.

Similarly, if the patient frequently changes position, it’s vital to ensure that the tubing is not getting caught or pinched against bed rails, furniture, or even their own limbs. Be mindful of how the patient is positioned and adjust the tube accordingly.

Gentle Realignment: A Step-by-Step Approach

If you identify a kink, the next step is to gently attempt to straighten it. Never force the tube, as this could cause damage to the nasal passages or even dislodge the tube entirely. Instead, try the following:

1. Reposition the Patient: Carefully reposition the patient to alleviate any pressure on the tube. Encourage them to sit upright or turn slightly to create more slack.

2. Adjust the External Portion: Gently manipulate the external portion of the tube, working your way down from the nose. Use a slow, deliberate motion to try to coax the kink out.

3. Avoid Force: If you encounter resistance, do not force it. Instead, try a different approach or seek assistance from a healthcare professional.

4. Secure the Tube: Once you have successfully straightened the kink, ensure that the tube is properly secured to prevent it from recurring. Use tape or a specialized NGT securing device.

By carefully inspecting the tube and adjusting patient positioning, you can often resolve kinks and restore the flow of fluids without resorting to more invasive measures. This simple yet effective technique can save time, reduce discomfort, and help maintain the patency of the NGT.

Trick 4: Small Volume, Targeted Impact – Breaking Up the Blockage

Sometimes, a blockage stubbornly resists gentle flushing and repositioning. When dealing with a particularly persistent obstruction in your NGT, a technique employing small, targeted fluid bursts can be surprisingly effective.

This approach utilizes the principle of creating localized pressure to dislodge the obstructive material. It’s akin to using a small hammer instead of a large one – precision over brute force.

The Concept of Localized Pressure

The core idea is to concentrate a small volume of fluid directly at the point of blockage.

By quickly injecting this fluid, you generate a brief surge of pressure that can help to break up the obstruction or dislodge it from the tube wall.

This method is particularly useful for breaking down clumps of medication or hardened secretions that have adhered to the inside of the NGT.

The "Push-Suck" Technique

The recommended procedure involves the following steps:

1. Draw up a small amount of fluid (either sterile water or saline solution) into a syringe – typically, 1-2 ml is sufficient.

2. Connect the syringe to the NGT.

3. Quickly inject the fluid into the tube.

4. Immediately following the injection, attempt to aspirate fluid back into the syringe.

This rapid "push-suck" action creates a localized turbulence that can help to loosen and dislodge the blockage.

Important Considerations for Safety

While this technique can be effective, it’s crucial to exercise caution:

• Always use a small volume of fluid. Overly forceful injections or large volumes could cause discomfort or even lead to aspiration of the fluid into the lungs.

• If you encounter resistance or the patient experiences any discomfort, stop immediately.

• This technique is not a substitute for proper flushing and medication administration practices.

• If repeated attempts are unsuccessful, it’s essential to consult with a healthcare professional. Continued forceful attempts can potentially damage the NGT or cause harm to the patient.

Why Small Volume Matters

The emphasis on small volume is paramount for several reasons. Firstly, it minimizes the risk of gastric distension and subsequent regurgitation.

Secondly, a smaller volume allows for a more concentrated force applied directly to the blockage, maximizing its effectiveness.

Finally, it reduces the likelihood of pushing the obstruction further down the tube, potentially exacerbating the problem. Remember, the goal is to dislodge the blockage, not to relocate it.

Sometimes, despite our best efforts with flushing and strategic pressure techniques, the blockage persists. Frequently, the culprit isn’t a simple build-up of secretions but rather the residue of improperly administered medications. Recognizing the link between medication administration and NGT obstruction is crucial for effective management.

Trick 5: Medication Management – Minimizing Medication-Related Blockages

Medications, while essential for treatment, can significantly contribute to NGT blockages. The problem arises particularly with solid oral dosage forms that require crushing or dissolving before administration.

The Medication Obstruction Connection

Crushing tablets, if not done meticulously, can leave behind large, undissolved particles. Similarly, some powdered medications may clump together if not properly mixed with water. These undissolved or poorly dispersed drug particles can then accumulate within the NGT, leading to partial or complete obstruction. The viscosity of some liquid medications can also contribute to blockages if not flushed adequately.

Strategic Medication Administration

To mitigate the risk of medication-related blockages, several key strategies should be implemented.

A proactive, thoughtful approach to medication administration can save time, reduce patient discomfort, and improve the longevity of the NGT.

Liquid Formulations: The Preferred Choice

Whenever possible, opt for liquid formulations of medications. This eliminates the need for crushing and dissolving, directly reducing the risk of particle-related blockages. Consulting with a pharmacist is essential to determine if suitable liquid alternatives are available. Many medications come in syrup, solution, or suspension forms that are readily compatible with NGT administration.

The Art of Crushing and Dissolving

If liquid formulations are unavailable, meticulous crushing and dissolving are paramount. Use a dedicated pill crusher to ensure a fine powder consistency. Subsequently, dissolve the powder in an adequate amount of warm water (check medication monograph for any temperature restrictions). Stir thoroughly until no visible particles remain. Remember, some medications may not dissolve completely, even with the best efforts. In these cases, consider if the medication is truly essential, or if there are alternative routes of administration.

The Pre- and Post-Medication Flush

Flushing the NGT with water both before and after medication administration is non-negotiable. The pre-flush helps to ensure that the tube is clear and ready to receive the medication. The post-flush clears any residual medication from the tube, preventing build-up and potential blockages. Use an appropriate volume of water – typically 30-50 ml – for each flush.

Consider Enteric Coating and Modified Release

Never crush enteric-coated or modified-release medications. These medications are designed to be absorbed in the small intestine, and crushing them can alter their release profile and potentially cause adverse effects. If a patient is unable to swallow these medications whole, contact the prescriber for an alternative.

Despite employing strategic medication administration techniques, maintaining the NGT’s patency requires a proactive and consistent approach beyond just addressing blockages as they arise. Regular flushing acts as a cornerstone for long-term success, preventing the build-up of troublesome residues and ensuring the tube remains functional for its intended purpose.

Trick 6: Maintaining Tube Patency – Regular Flushing for Long-Term Success

Preventative care is paramount in avoiding NGT obstructions. Establishing and adhering to a routine flushing schedule is a simple yet incredibly effective measure.

This section delves into the importance of regular flushing and provides guidance on establishing an appropriate flushing protocol.

The Importance of Routine Flushing

Regular flushing serves multiple crucial functions.

It physically removes residual feeding formula, medications, and secretions that can accumulate within the tube.

Flushing also helps to maintain the tube’s internal diameter, preventing the formation of stubborn blockages.

Furthermore, consistent flushing can help to prevent bacterial growth within the tube, contributing to overall hygiene.

Think of it as preventative maintenance for your NGT.

Establishing a Flushing Schedule

The optimal flushing schedule depends on individual patient needs and the frequency of medication or feeding administration.

As a general guideline:

• Flush the NGT every 4-6 hours, even when not in active use.
• Always flush the NGT immediately after each medication administration.
• Flush the NGT before and after each bolus feeding.
• For continuous feeds, consider flushing every 8-12 hours.

Consult with a healthcare professional to determine the most appropriate flushing schedule for each individual patient. They can provide tailored guidance based on the patient’s specific needs and medical history.

Choosing the Right Flushing Solution and Volume

Sterile water is generally the preferred solution for routine flushing, especially in patients with compromised immune systems.

Sterile saline (0.9% NaCl) is an acceptable alternative and may be recommended in certain situations, such as when the patient is on fluid restriction.

The appropriate volume of fluid to use for routine flushing is also important.

• For adults, a typical volume is 30-50 ml.
• For children, the volume should be adjusted based on their age and size, typically ranging from 5-30 ml.

Always use a gentle, slow flushing technique to avoid causing discomfort or distension.

Maintaining patency through regular flushing is a cornerstone of NGT care, but even the most diligent efforts can sometimes fall short. Knowing when to escalate the situation and seek professional medical assistance is crucial for patient safety and optimal outcomes.

Trick 7: When to Call the Professionals – Recognizing the Limits of DIY Solutions

While these seven tricks provide practical solutions for many NGT blockages, it’s essential to recognize when home remedies have reached their limit. Persistent blockages, signs of patient distress, or concerns about tube integrity necessitate prompt intervention from a healthcare professional. Attempting to force a solution beyond a certain point can be counterproductive and potentially harmful.

Recognizing the Red Flags

There are several key indicators that signal the need for professional help:

• Persistent Blockage: If you’ve diligently tried several of the tricks outlined above, including water and saline flushes, position checks, and small volume bursts, and the tube remains blocked, it’s time to seek expert assistance. Prolonged blockage can lead to dehydration, nutritional deficiencies, and medication delays.

• Patient Discomfort or Distress: Any signs of pain, gagging, choking, vomiting, or significant abdominal distention should be taken seriously. These symptoms could indicate improper tube placement, gastric irritation, or other complications that require immediate medical attention.

• Suspected Tube Dislodgement or Displacement: If you suspect that the NGT has become dislodged or displaced, do not attempt to reinsert it yourself. A healthcare professional is trained to assess tube placement accurately and safely.

• Bleeding or Unusual Drainage: The presence of blood in the aspirate or drainage from the NGT is a concerning sign that warrants immediate evaluation by a healthcare provider.

• Difficulty Breathing: Any respiratory distress should be treated as an emergency. If the patient experiences shortness of breath, wheezing, or difficulty breathing, seek immediate medical attention.

The Risks of Forcing a Solution

It’s natural to want to resolve a blocked NGT quickly, but attempting to force the tube open can cause significant harm. Applying excessive pressure can damage the tube itself, leading to cracks, breaks, or even perforation of the esophagus or stomach.

Furthermore, forcing fluid into a blocked tube can increase the risk of aspiration, where fluids enter the lungs. This can lead to pneumonia and other serious respiratory complications, especially in vulnerable patients.

The Role of Healthcare Professionals

Healthcare professionals, including nurses and doctors, have specialized knowledge and equipment to address complex NGT blockages safely and effectively. They can:

• Assess the cause of the blockage through physical examination and imaging studies (e.g., X-ray).

• Employ advanced techniques to clear the blockage, such as using specialized declogging devices or enzymatic solutions.

• Replace the NGT if it is damaged or irreparably blocked.

• Manage any complications that may arise from the blockage or its treatment.

Remember, your well-intentioned efforts can only go so far. When in doubt, err on the side of caution and seek the guidance of a qualified healthcare professional. Their expertise is invaluable in ensuring patient safety and restoring proper NGT function.

Prevention is Paramount: Long-Term Strategies for a Clear NGT

While knowing how to address a blocked nasogastric tube (NGT) is essential, proactive prevention is the most effective strategy for maintaining tube patency and ensuring consistent delivery of nutrition and medication. Establishing a robust preventative routine minimizes disruptions, reduces patient discomfort, and lessens the need for potentially invasive interventions.

The Power of Consistent Flushing

Regular flushing is the cornerstone of NGT maintenance. This simple act physically clears the tube of residual formula, medications, and secretions before they can solidify and cause a blockage.

Inconsistent or inadequate flushing is a primary driver of NGT occlusions. A consistent flushing schedule should be established, typically every 4-6 hours, and always after each medication administration or feeding.

The appropriate volume of fluid is also critical. Generally, 30-50 ml of sterile or distilled water is sufficient for routine flushing. However, always follow the specific instructions provided by the healthcare team.

Minimizing Obstruction Risks: Practical Tips

Beyond regular flushing, several other proactive measures can significantly reduce the likelihood of NGT blockage.

These steps require vigilance and attention to detail but can dramatically improve long-term tube functionality.

Medication Administration Best Practices

Medications are a frequent culprit in NGT obstructions. Whenever possible, opt for liquid formulations of medications. These are less likely to leave behind residue that can solidify and block the tube.

When liquid forms are unavailable, meticulous preparation of solid medications is crucial. Crush tablets thoroughly into a fine powder and dissolve them completely in an adequate amount of water. Ensure no undissolved particles remain before administering the medication through the NGT.

Always flush the tube before and after administering any medication to clear the tube and prevent interactions between different drugs.

The Importance of Hydration

Adequate hydration plays a vital role in maintaining thin, easily flushed secretions. Dehydration leads to thicker mucus, increasing the risk of blockages.

Ensure the patient receives sufficient fluids, either orally or intravenously, as prescribed by their healthcare provider. Monitoring urine output and skin turgor can help assess hydration status.

Vigilance for Kinks and Displacement

Regularly inspect the NGT along its entire length for kinks, bends, or signs of displacement. Patient movement, coughing, or even improper positioning can cause the tube to kink or migrate.

Reposition the patient as needed to alleviate any kinks in the external portion of the tube. Secure the tube properly to prevent unintentional displacement. If you suspect the tube has migrated, do not attempt to reinsert it yourself; contact a healthcare professional immediately.
