What Happens If Water Gets Under a PICC Line Dressing?

Peak Medical — Tue, 08 Sep 2026 12:02:24 +0000

Having a PICC line means taking a little extra care during daily activities. Showering is one of them. But what if water gets under the dressing?

A wet dressing may not protect the PICC site as it should. Wet or damp dressings can breed bacteria meaning increased infection risk. Moisture can also make the dressing loose or affect the adhesive. If water gets underneath, it is best to contact your healthcare team. They can tell you if the dressing needs to be changed.

What Should You Do If Water Gets Under the Dressing?
First, do not panic. Do not lift or remove the dressing unless you have been trained to change it.

Tell your nurse or healthcare team what has happened. They can advise you on the next step. In some cases, the dressing may need to be replaced.

Do not try to dry the area by lifting the dressing. This can disturb the PICC line or increase the chance of contamination.

If you have been trained to change your dressing at home, follow the steps given by your healthcare professional.

Can a Waterproof PICC Dressing Help?

A waterproof or water-resistant dressing can help keep moisture away from the PICC site. This can be useful during activities such as showering. However, waterproof does not mean that the PICC line can be placed underwater. You should still follow your healthcare team's advice about showering, bathing and swimming.

For healthcare providers looking for a waterproof PICC line dressing supplier, it is worth looking at more than water protection. Good adhesion, breathability, comfort and site visibility are also important, all of these factors can support you in reducing any infection risk.

Peak Medical's Cath Dry is a sterile, water-resistant dressing. It also has a moisture indication ring. The ring provides a visible sign when moisture enters the dressing.

How Can You Keep Your PICC Dressing Dry?

A few simple steps can help. Before showering, use the protection recommended by your healthcare team. Keep the PICC area away from direct water spray. Avoid soaking or submerging the PICC line unless your healthcare professional says it is safe. After showering check the dressing. Is it still firmly attached? Does it look dry? If it is wet, loose or damaged, contact your healthcare team.

Do not change the dressing yourself unless you have been trained to do so.

When Should You Contact Your Healthcare Team?
Contact your healthcare team if water gets under the dressing. This is especially important if the dressing is wet or has started to come loose. Also look out for redness, swelling, pain or discharge around the PICC site. Fever or feeling unwell should also be reported.

Your healthcare team can check the site and tell you what to do next.

Choosing a Central Venous Catheter Dressing Supplier

When choosing a waterproof central venous catheter dressing supplier, water protection is only one factor to consider. Healthcare providers may also look at adhesion, comfort, breathability, site visibility and moisture monitoring.

Peak Medical offers specialist catheter-care products, including Cath Dry. Its water-resistant design and moisture indication feature can support everyday catheter care.

How Medical Devices for Indwelling Catheter Infection Control Are Reducing CAUTI Risks

Peak Medical — Fri, 17 Jul 2026 06:38:41 +0000

Why do so many long-term catheter users keep getting infections, even after treatment? For thousands of patients, the cycle of pain, blockages, and repeated antibiotic courses simply never ends.

In this article, we are going to learn how medical devices for indwelling catheter infection are changing the way healthcare providers tackle this problem.

The Real Reason Catheter Infections Keep Coming Back

Bacteria don't just float freely around a catheter. They stick to the surface and form a tough, sticky layer called biofilm and once it forms, it's very difficult to manage and reduce the infection without changing the catheter. Antibiotics can struggle to reach bacteria embedded inside biofilm, so even after a course of treatment, infection can return.

Biofilm can also trap minerals and debris over time, potentially blocking the catheter tube and causing urine to bypass the catheter, pain, and unplanned hospital visits. Standard catheter care only cleans the outside surface — it doesn't reach the inner wall where bacteria are colonising and multiplying.

That's why the same patients often face repeated infections, repeated antibiotic courses, and growing concern around antibiotic, not to mention prolonged hospital stays and risk of urosepsis.

This is exactly where dedicated medical devices for indwelling catheter infection management play a critical role.

Key Medical Devices for Indwelling Catheter Infection Prevention

UroShield —Surface Acoustic Wave Device

UroShield is an ultrasound device that clips directly onto an indwelling urinary catheter. According to the manufacturer, it generates low-frequency, low-intensity Surface Acoustic Waves that travel up and down the catheter, these surface acoustic waves interfere with bacterial attachment to the catheter surface, and reduce biofilm development.

Uroshield benefits include helping reduce bacterial attachment, lowering blockage risk from sediment accumulation, reducing catheter-related pain, and reducing the need for repeated antibiotic courses.

Individual results may vary, and patients should speak with their healthcare professional to determine suitability. A full starter kit is required — the actuator is single-use and should be replaced with every catheter change.

Meatal Dilators — Tapered Tip Urethral Access Devices

Meatal dilators feature a tapered tip designed to gently widen the urethral opening for easier passage, particularly helpful where strictures are restricting urinary flow.

When urinary flow is restricted urine can remain in the bladder and not empty completely this increases the UTI risk to high. By opening up the strictures urine can flow easier in turn allowing full bladder emptying.

ISC Catheters

Under the recommendation and training of the specialist team it may be suggested the patients carry out their own catheterization this is known as intermittent self-catheterization (ISC) this means the bladder can be fully emptied multiple times a day without the discomfort of leaving the catheter in situ and increasing catheter associated urinary infections (CAUTIs)

One of the limitations of this is the patients ability to be able carry out the procedure multiple times a day and the trauma that can be caused to the ureter. When repeated trauma is caused the infection risk increases again.
