BD has designed their IV flush to work seamlessly with various infusion systems, prioritizing patient care by reducing catheter occlusions and ensuring smooth and effective IV therapy.

What is an IV Flush?
Think of an IV flush as simple, yet essential, maintenance for an intravenous line. It involves pushing a small amount of sterile solution—usually saline—through the IV catheter. This quick procedure is a cornerstone of IV therapy, performed to ensure the line remains open, clean, and ready for use. Whether you're administering medication or drawing blood, a properly flushed IV line is key to preventing complications and ensuring the system functions exactly as it should. It’s a fundamental step that protects the patient and maintains the integrity of the entire IV setup, from the catheter to the tubing.
The primary goal is to confirm that the IV is patent, meaning it's not blocked or clotted. Flushing clears out any residual medication or blood that could obstruct the flow or interact with the next medication administered. It’s a proactive measure that significantly reduces the risk of infection, blockages, and other complications that can arise from a poorly maintained IV line. By keeping the line clear, you ensure that your patient receives their treatment safely and effectively every single time.
The Purpose of Flushing an IV Line
Flushing an IV line serves two critical functions: it keeps the line clear and ensures medications are delivered correctly. Essentially, it's a safety check that confirms the IV is working properly before and after use. By pushing saline through the catheter, you can physically feel for resistance, which might indicate a blockage or that the catheter has dislodged from the vein. This simple action helps prevent serious issues like infiltration, where fluid leaks into the surrounding tissue, or phlebitis, which is inflammation of the vein. It’s a small step that has a big impact on patient safety and the success of IV therapy.
Clearing the Line and Preventing Blockages
The most immediate purpose of an IV flush is to prevent the line from becoming blocked. When an IV isn't in continuous use, small blood clots can form at the tip of the catheter, creating an occlusion. Flushing the line with saline pushes these tiny clots out and keeps the pathway clear. This is especially important for peripheral IVs (PIVs) that are accessed intermittently. A consistent flushing schedule ensures the line is always ready for the next medication dose or fluid administration, saving you the time and trouble of having to replace a clotted IV.
Ensuring Proper Medication Delivery
Flushing is also vital for effective medication delivery. When you administer medication through an IV, some of it can remain in the catheter or tubing. Flushing after administration ensures the full dose reaches the patient's bloodstream. It also clears the line to prevent any chemical interactions between incompatible medications that might be given sequentially. According to ivWatch, this practice keeps the IV line clean and significantly lowers the chance of infection or blockages, making sure the treatment is both safe and effective.
Common IV Flush Solutions
While several types of solutions can be used for an IV flush, one stands out as the industry standard due to its safety and compatibility with the human body. The choice of solution depends on the patient's specific needs, the type of IV line, and the medications being administered. However, for routine flushes, the goal is always to use a solution that is sterile and isotonic to maintain the patency of the line without causing irritation or fluid shifts. Having reliable anesthetic and IV supplies on hand is crucial for any practice.
0.9% Normal Saline
The most common solution used for IV flushes is 0.9% normal saline. This sterile, isotonic mixture of salt and water closely matches the salt concentration of your blood, making it the safest and most compatible option for most patients. It effectively clears the line without disrupting the body's natural electrolyte balance. Pre-filled normal saline syringes are a staple in nearly every clinical setting because they are convenient, reduce the risk of contamination from drawing up saline from a multi-dose vial, and ensure accurate volume for every flush.
Other Solutions: Lactated Ringers, Dextrose, and Heparin
Although normal saline is the go-to, other solutions are sometimes used in specific clinical situations. Lactated Ringer's, another isotonic solution, can be used as an alternative to saline. Dextrose solutions may be used if there's a concern about a patient's sodium levels. In some cases, a heparin flush is used, particularly for central lines, to prevent blood clots. Heparin is an anticoagulant, but its routine use has become less common due to the effectiveness of saline and the potential risks associated with heparin, such as heparin-induced thrombocytopenia (HIT).
Understanding the "Saline Lock"
You'll often hear the term "saline lock" in reference to IVs that aren't being used for continuous fluid infusion. A saline lock, also known as a "hep-lock" (though heparin is less commonly used now), is simply an IV catheter connected to a short tube that is capped off with a port. This device allows for intermittent access to a vein without requiring the patient to be hooked up to an IV bag and pole continuously. It gives patients more freedom to move around while still providing a ready access point for medications or fluids when needed. The "lock" is maintained by flushing it with saline periodically to keep it from clotting.
The Correct IV Flush Procedure: A Step-by-Step Guide
Following a standardized procedure for flushing an IV line is critical for patient safety and maintaining the integrity of the catheter. Each step, from inspection to clamping, is designed to prevent complications like infection, infiltration, and air embolism. Mastering this routine technique ensures that you can perform it confidently and efficiently, providing the best possible care for your patients. It’s about being meticulous and consistent. Taking a moment to follow these steps correctly can prevent significant problems down the road, making it a non-negotiable part of IV management in any clinical setting.
Step 1: Inspect the IV Site
Before you do anything else, always start by assessing the IV site. Look for any signs of complications, such as redness, swelling, pain, or fluid leakage. Gently palpate the area around the insertion site to check for tenderness or firmness. This initial inspection helps you confirm that the catheter is still correctly positioned in the vein and that there are no early signs of infiltration or phlebitis. If you notice anything unusual, you should address the issue before proceeding with the flush. Patient communication is key here—ask them how the site feels and if they are experiencing any discomfort.
Step 2: Clean the IV Port
Proper hygiene is non-negotiable. Before connecting your saline syringe, you must thoroughly clean the access port, or "hub," of the IV catheter. Use an alcohol swab and scrub the hub vigorously for at least 15 seconds, then allow it to air dry completely. This step is crucial for preventing bacteria on the surface of the port from being introduced into the bloodstream, which could cause a serious infection. Don't skip this or rush through it; a clean port is one of the most effective ways to prevent catheter-related bloodstream infections (CRBSIs).
Step 3: Use the "Push-Pause" Flushing Technique
Instead of pushing the saline in one continuous motion, use the "push-pause" or pulsatile flushing technique. This involves injecting a small amount of saline (about 1-2 mL at a time), pausing for a moment, and then repeating until the full amount has been administered. This turbulent, start-and-stop motion is more effective at clearing debris and residue from the inside of the catheter than a steady, continuous flush. It creates a scrubbing effect that helps remove any buildup of fibrin or medication deposits, ensuring the line remains completely clear and patent.
Step 4: Manage Pressure with the Right Syringe Size
It might seem counterintuitive, but smaller syringes generate more pressure than larger ones. Using a syringe smaller than 10 mL to flush an IV line can create enough pressure to damage or rupture the catheter, especially with smaller gauge catheters. For this reason, a 10 mL syringe is the standard size recommended for flushing most IV lines. Always use a syringe that is appropriate for the type and size of the catheter you are working with to avoid causing unnecessary damage or complications for the patient.
Step 5: Follow the Proper Clamping Sequence
The final step involves clamping the IV line correctly to prevent blood from backing up into the catheter, which could lead to a clot. For a positive pressure technique, continue to push the last bit of saline as you clamp the line. This pushes fluid out of the catheter tip, preventing blood reflux. For negative pressure or neutral pressure ports, you can clamp the line right after the flush is complete. Knowing the type of connector you're working with is important for using the correct clamping sequence and keeping the line patent until its next use.
When and How Often to Flush an IV Line
Knowing when to flush an IV line is just as important as knowing how to do it. The frequency of flushing depends on the type of IV and how it's being used. A consistent flushing schedule is key to maintaining catheter patency and preventing complications. For some IVs, this might mean flushing every few hours, while for others, it's only done before and after medication administration. Establishing a clear routine based on best practices ensures that every IV line is properly maintained, reducing the risk of occlusions and infections for your patients.
Routine Flushing for Intermittent Use
For IV lines that are not in continuous use, such as a saline lock, routine flushing is essential to keep them from clotting. The standard protocol is typically to flush the line every eight hours, though this can vary based on your facility's policies. This regular maintenance ensures the line remains patent and ready for use whenever it's needed. A consistent schedule helps prevent the frustration of finding a clotted line right when you need to administer a critical medication, saving both time and resources while minimizing discomfort for the patient.
Before and After Medication Administration
Flushing an IV line both before and after giving medication is a critical safety measure. Flushing before administration confirms that the line is patent and the catheter is in the correct position, ensuring the medication will be delivered directly into the bloodstream. Flushing after administration serves two purposes: it pushes any remaining medication out of the catheter to ensure the patient receives the full dose, and it clears the line to prevent any potential incompatibilities with the next medication that might be given.
When a Flush Isn't Necessary: Continuous Infusions
If a patient is receiving a continuous infusion of fluids, routine flushing is generally not necessary. The constant flow of fluid through the IV line is usually sufficient to keep the catheter patent and prevent clotting. In this case, the line is only flushed when the infusion is stopped or interrupted, or when the IV bag is changed. Once the continuous infusion is discontinued and the line is converted to a saline lock, you would then resume a regular flushing schedule to maintain its patency for intermittent use.
Patient Safety, Comfort, and Potential Side Effects
While an IV flush is a routine and generally safe procedure, patient safety and comfort should always be the top priority. It's important to be aware of what the patient should expect, as well as the potential side effects and signs of complications. Clear communication with the patient can help alleviate anxiety and ensure they know when to alert you if something doesn't feel right. Being vigilant and responsive to a patient's experience during the flush is key to preventing more serious issues and ensuring a positive outcome.
What a Patient Should Expect During a Flush
Most patients won't feel much during a saline flush, though some may notice a brief cool sensation in their arm as the fluid enters the vein. It's important to let them know that the procedure should not be painful. You should always tell your patient to speak up immediately if they feel any pain, burning, or discomfort during the flush, as this could be a sign that the catheter has dislodged or that there is another issue at the IV site. Reassuring them and encouraging open communication helps build trust and ensures their safety.
Recognizing Potential Side Effects and Signs of Infection
While uncommon, side effects can occur. It's important to monitor the IV site for signs of infiltration (swelling, coolness, and tenderness), phlebitis (redness, warmth, and a palpable cord along the vein), or infection (pus, fever, and increased pain). If a patient complains of dizziness or develops a rash, it could indicate an allergic reaction, though this is rare with saline. Promptly recognizing and addressing these signs can prevent more serious complications and ensure the patient receives the appropriate care.
IV Flush Safety During Pregnancy and Breastfeeding
For patients who are pregnant or breastfeeding, a 0.9% normal saline flush is considered very safe. Saline is simply salt and water, which is naturally present in the body and poses no risk to the mother or baby. However, if a different type of flush solution, such as one containing heparin, is being considered, it's important to confirm its safety with the ordering provider. As with any procedure, clear communication and adherence to established safety protocols are essential when caring for these patient populations.
Proper Storage and Handling of IV Flush Syringes
The integrity of your supplies is just as important as your technique. Proper storage and handling of pre-filled IV flush syringes are essential for preventing contamination and ensuring they are safe and effective for patient use. From the moment they arrive from a trusted supplier like SurgiMac to the second you use them, these sterile devices must be handled with care. Establishing a clear protocol for storage and inspection in your practice helps maintain a high standard of care and protects your patients from potential harm.
Visual Inspection Before Use
Before using any pre-filled syringe, a quick visual inspection is a critical safety check. Always look at the liquid to ensure it is clear and free of any particles or discoloration. Check the packaging for any signs of damage or tampering, and confirm that the expiration date has not passed. Using a compromised or expired product could introduce contaminants into the patient's bloodstream or be less effective. This simple, quick check is a fundamental step in preventing medication errors and ensuring patient safety.
Correct Storage Conditions
Pre-filled saline flush syringes should be stored according to the manufacturer's instructions, which typically means keeping them at room temperature and away from direct sunlight or extreme heat. They should be kept in their original, unopened packaging until they are ready to be used to maintain their sterility. Organizing your supplies in a clean, dry, and easily accessible area ensures that you can quickly grab what you need while also protecting the integrity of your inventory. Proper storage is a simple but vital part of supply management.

Frequently Asked Questions
Why is using a 10 mL syringe so important for flushing an IV? It might seem like a small detail, but syringe size has a major impact on the pressure exerted on the IV catheter. Smaller syringes generate significantly more pressure, which can be enough to damage or even rupture the catheter inside the vein. Sticking with a 10 mL syringe is the industry standard because it provides a safe, controlled pressure that effectively clears the line without putting the catheter or the patient at risk.
Is the "push-pause" flushing technique really that important? Yes, it absolutely is. A steady, continuous flush can be less effective at clearing out the tiny bits of residue or fibrin that can build up inside the catheter. The "push-pause" method creates a turbulent, pulsating flow that acts like a gentle scrubbing motion on the catheter's inner walls. This technique is far more effective at dislodging any potential buildup, ensuring the line is completely clear and reducing the chances of a blockage forming later.
What are the most critical signs of a problem I should look for at the IV site? Before you flush, always perform a quick but thorough assessment of the IV site. The most immediate red flags are swelling, redness, and any patient complaints of pain or burning. Swelling combined with coolness at the site could indicate infiltration, where fluid is leaking into the surrounding tissue. Redness, warmth, and tenderness along the vein are classic signs of phlebitis, or vein inflammation. Always encourage your patient to speak up if anything feels off during the flush.
Are there situations where normal saline isn't the right choice for a flush? While 0.9% normal saline is the go-to for the vast majority of routine IV flushes, there are specific clinical scenarios where an alternative might be used. For certain central lines, a heparin flush may be ordered to prevent clots, though this is becoming less common. In other cases, a provider might specify a different solution like Lactated Ringer's based on a patient's specific electrolyte needs. However, for standard peripheral IVs, normal saline is almost always the safest and most effective choice.
How do I decide between B. Braun and BD flush solutions for my practice? Both B. Braun and BD are excellent brands with a strong reputation for quality, so you can't go wrong with either. The choice often comes down to specific features and facility preference. For instance, B. Braun is known for its preservative-free formula, which is a great choice for sensitive patients.
