How to Properly Tape and Secure an IV Line

Roughly one in three peripheral IV catheters fails before treatment is finished, and catheter dislodgement from poor securement is one of the top reasons why. A large secondary analysis of nearly 12,000 catheters found an all-cause failure rate of 36%, with dislodgement alone accounting for 7% of those failures.¹ The way you prepare the skin, choose a dressing, and anchor the tubing directly determines whether an IV stays put or needs to be restarted, so the details of taping and securement matter more than most people realize.

Why Proper Securement Matters So Much

When an IV line shifts even slightly, the catheter tip can irritate or puncture the vessel wall, leading to infiltration, phlebitis, or complete dislodgement. Infiltration and occlusion were the most common complications in that large analysis, affecting about 23% of all catheters, while phlebitis hit around 12%.¹ Each failure means a new needle stick for the patient, more time for staff, and additional cost. Proper taping and securement is the single most modifiable factor in preventing these outcomes, because even a perfectly placed catheter will fail if it is not held stable.

Preparing the Skin Before You Apply Anything

The adhesive on any tape or dressing is only as good as the surface it sticks to. Oily, sweaty, or damp skin dramatically reduces how well a dressing holds, so site preparation starts before the catheter even goes in. Cleaning the insertion area with an antiseptic serves double duty: it reduces bacterial load and removes oils that interfere with adhesion.

Chlorhexidine-based solutions have become the standard for skin antisepsis around vascular access sites. A meta-analysis of eight randomized trials involving over 4,000 short-term catheters found that chlorhexidine preparations cut catheter-related bloodstream infections by roughly half compared to aqueous povidone-iodine.² The alcohol component in many chlorhexidine solutions also helps degrease the skin, which improves how firmly the dressing bonds. Let the antiseptic dry completely before placing any adhesive. Applying tape to wet skin is one of the most common reasons dressings peel up within the first few hours.

If there is significant hair at the insertion site, clip it rather than shaving. Shaving creates micro-abrasions that increase infection risk and can also cause irritation under the adhesive. Clipping close to the skin provides a smooth surface for the dressing without breaking the skin barrier.

Using a Barrier Film to Protect the Skin

For patients who will have an IV in place for more than a day or two, or anyone with sensitive or fragile skin, applying a liquid barrier film before the dressing can make a real difference. Barrier films create a thin protective layer between the skin and the adhesive. They reduce the peel force when the dressing is eventually removed, which means less skin stripping and less pain.

Not all barrier films perform equally. A comparative bench study found that one widely used product significantly outperformed others in barrier durability while also scoring highest in breathability and reduction of peel force.³ In a clinical trial on catheter dressings, using an acrylic terpolymer barrier film beneath transparent dressings led to fewer dressing disruptions and significantly fewer skin-integrity problems compared to bare skin.⁴ If the dressing stays intact longer, you handle the site less, which reduces the chance of accidentally tugging the catheter and also reduces infection exposure.

Choosing a Dressing Type

The three main categories of IV dressings are gauze held with tape, transparent polyurethane film dressings, and integrated securement dressings that combine a clear window with a built-in stabilization platform. Each has trade-offs.

Transparent polyurethane dressings are the current workhorse in most hospitals. They allow visual inspection of the insertion site without removal, and they hold up better against dislodgement than gauze. A systematic review and meta-analysis confirmed that transparent polyurethane dressings were associated with lower dislodgement rates compared to gauze in adults.⁵ Gauze still has a role when there is oozing at the site or when the skin cannot tolerate adhesive film, but it should be considered a backup option rather than a default.

Integrated securement dressings take the transparent film concept further by adding a stabilizing frame or pad that anchors the catheter hub. In a pediatric trial, an integrated securement dressing reduced IV failure to 29% compared to 45% with a standard bordered polyurethane dressing.⁶ That is a meaningful difference when you are trying to avoid restarting an IV on a small child.

Tape Alone Versus Mechanical Securement Devices

Plain non-sterile tape wrapped around the catheter hub is still the most common securement method worldwide, largely because it is cheap and always available. But the evidence strongly suggests it is one of the weakest options. A comparison study found that non-sterile tape produced only an 8% IV survival rate when the goal was to keep a catheter in place for 96 hours. A die-cut tape device performed similarly at 9%. In contrast, a mechanical securement device achieved a 52% survival rate over the same period.⁷ The gap between tape and a dedicated device is striking.

Mechanical securement devices use adhesive pads with built-in clips or frames that grip the catheter hub and redirect tension away from the insertion point. Products in this category use polyurethane or silicone adhesives and have shown significant improvements in durability and patient comfort compared to tape alone.⁸ Bench testing of two such devices showed that newer designs can resist greater peel-off and perspiration-related pull-out forces, which matters for active or sweating patients.⁹

If you are taping an IV at home or in a setting where mechanical devices are not available, the key principles are the same ones these devices were designed to accomplish mechanically: anchor the hub flat to the skin, create a strain-relief loop in the tubing so that a tug on the line pulls against the tape rather than the catheter, and press the adhesive down firmly so there are no lifted edges where moisture can creep in.

Tissue Adhesive as an Alternative to Tape

Medical-grade tissue adhesive, usually a cyanoacrylate glue similar to what is used for wound closure, is gaining traction as a securement strategy. A drop of glue applied around the catheter hub bonds it directly to the skin, eliminating the need for a bulky dressing to hold the line in place.

The same meta-analysis that compared dressing types found that tissue adhesive significantly reduced overall IV failure compared to transparent polyurethane dressings, cutting dislodgement by about 40% and occlusion by about 27%.⁵ A small pilot trial similarly showed the lowest catheter failure rate in the tissue-adhesive group at 14%, compared to 38% in the standard-care group.¹⁰

In neonates, cyanoacrylate adhesive is already widely used to secure central venous catheters and is expanding into peripheral IV securement.¹¹ A randomized trial in adults using cyanoacrylate glue for midline and PICC securement showed significantly less peri-catheter bleeding and fewer dislodgements in the first 24 hours.¹² Glue may also reduce micro-displacement at the insertion site, which could lower the rate of mechanical phlebitis.¹³ The downside is that removal can be tricky and sometimes requires a solvent, especially in fragile neonatal skin.

Where You Place the IV Changes How Well It Stays

Even the best taping job can be defeated by catheter placement at a joint. The same large dataset of nearly 12,000 catheters found that insertion at flexion points, particularly the inner elbow and the hand or wrist, was significantly associated with higher rates of failure, infiltration, occlusion, and dislodgement compared to the forearm.¹ Joint motion loosens the dressing, kinks the catheter, and drives the tip into the vessel wall. When you have a choice, the mid-forearm is the most securement-friendly location.

If the IV must go in the hand or near a joint, extra steps are warranted. A small splint or arm board can limit flexion and reduce the mechanical stress on the tape. In neonates, researchers have compared splinting to tissue adhesive for this exact purpose, recognizing that tiny joints move constantly and standard dressings cannot keep up.¹³ The strain-relief loop in the tubing becomes even more critical at these sites: loop the extension set and tape it down separately from the insertion site so that any pull on the line is absorbed by the loop rather than transmitted to the catheter.

Infection Risks From Tape Itself

One often-overlooked concern is that the tape roll sitting at the bedside can become a bacterial reservoir. A study that cultured specimens from partially used tape rolls in a hospital found that 74% were colonized with pathogenic bacteria on their outer surface. When the outer layer was discarded, only 5% of specimens from an inner layer showed significant growth.¹⁴ The practical takeaway: if you are using a communal roll of tape, peel off and discard the outermost wrap before tearing off a fresh strip. Better yet, use single-patient tape rolls or pre-packaged sterile dressing kits.

Chlorhexidine-Impregnated Dressings

For central venous catheters and other high-risk lines, chlorhexidine-impregnated dressings add a layer of antimicrobial protection directly at the insertion site. A meta-analysis found that these dressings cut catheter colonization by about half compared to standard transparent dressings.¹⁵ Another meta-analysis reported a reduction in overall catheter or exit-site bacterial colonization from about 27% with standard dressings to about 14% with chlorhexidine-impregnated versions.¹⁶ These dressings are most commonly used for central lines and are not standard practice for peripheral IVs, but they illustrate how the dressing material itself can contribute to infection prevention beyond just holding the catheter in place.

When to Change or Replace the Dressing

A dressing should be changed whenever it is visibly soiled, damp, or peeling up at the edges. Beyond that, the question of how often to do scheduled changes is less settled than you might expect. A Cochrane review of five trials involving over 2,200 participants compared longer dressing intervals (5 to 15 days) with shorter intervals (2 to 5 days) for central venous access devices and found no clear difference in catheter-related bloodstream infections between the two approaches.¹⁷ The evidence was graded as low quality, so the honest answer is that we do not yet know the optimal interval with certainty.

For peripheral IVs specifically, the old tradition of routinely replacing catheters every 72 to 96 hours has also been challenged. A randomized trial comparing routine replacement with clinically indicated replacement (meaning the line stays until there is a reason to remove it) found no significant difference in phlebitis or infiltration rates, and clinically indicated replacement was cheaper.¹⁸ An earlier observational study looking at catheters in place for up to 28 days similarly could not demonstrate an increased risk of complications after the traditional three-day cutoff.¹⁹ The practical lesson: inspect the site regularly and change the dressing or catheter when something looks wrong, rather than on an arbitrary schedule.

Pediatric and Fragile-Skin Considerations

Children and elderly patients present special securement challenges. Children move constantly, have smaller veins, and are more likely to pull at unfamiliar things attached to their bodies. The pediatric trial mentioned earlier showed that both integrated securement dressings and tissue adhesive outperformed standard bordered dressings in reducing IV failure in children.⁶ For infants and neonates, the stakes are even higher because skin is thinner and more easily damaged by adhesive removal.

A randomized trial in children found that total costs, including the economic burden of catheter failure and reinsertion, were lower when more advanced securement strategies were used. The combination of an integrated securement dressing with tissue adhesive produced lower total direct costs than standard care, because even though the materials cost slightly more, the savings from fewer failures more than compensated.²⁰

For anyone with fragile skin, whether due to age, steroid use, or a skin condition, adhesive removal is as important as adhesive application. Medical adhesive-related skin injuries are a recognized and underappreciated problem, and they often can be prevented by using silicone-based adhesive removers during dressing changes rather than just peeling the tape off.²¹ Slow, low-angle removal, pulling the dressing back flat against the skin rather than lifting it up, further reduces the risk of skin tears.

Practical Taping Steps When You Do Not Have Specialized Devices

Specialized dressings and mechanical securement devices are ideal, but plenty of situations call for making do with standard transparent dressings and medical tape. Here is what matters most when you are working with basic supplies:

• Clean and dry: Prep the skin with antiseptic and wait for it to dry completely before applying any adhesive. Moisture is the enemy of adhesion.
• Anchor the hub: Place a small strip of sterile tape across the catheter hub to hold it flat against the skin, then cover the site with a transparent dressing. The hub should not rock or pivot under the dressing.
• Create a strain-relief loop: Coil the extension tubing into a loop and tape it to the skin a few inches away from the insertion site. When someone catches the tubing on a bedrail or IV pole, the force pulls against this loop rather than against the catheter itself.
• Seal the edges: Press the dressing edges down firmly, especially the proximal edge closest to the catheter hub. Air pockets and lifted edges invite moisture, and moisture leads to both dressing failure and bacterial growth.
• Label the dressing: Write the date and time of insertion on the dressing with a marker. This helps anyone caring for the patient know how long the site has been in use without having to dig through the chart.

Avoid wrapping circumferential tape all the way around a limb. It can act as a tourniquet if swelling develops, and it makes site inspection impossible without full removal. If extra security is needed for a restless patient, consider a tubular net sleeve over the site rather than more tape.

Why the Outer Layer of Tape Deserves Its Own Thought

It sounds almost too simple to matter, but the outermost layer of a tape roll is one of the dirtiest surfaces at a bedside. The 74% contamination rate found in hospital tape rolls reflects the reality that tape sits open in rooms with airborne bacteria, gets handled by multiple people, and rolls across bedside tables.¹⁴ Discarding the outermost wrap before tearing off a strip dropped the contamination rate to 5%. That simple habit costs nothing and takes about two seconds. If your facility uses pre-cut sterile tape strips packaged individually, that problem is already solved, but many settings still rely on communal rolls.
