Relevant Peripheral IV Cannula Dressings: Advantages & Disadvantages

Peripheral intravenous (IV) cannula dressings play a crucial role in ensuring the safety and efficacy of intravenous therapy. These dressings are designed to secure the IV cannula in place, protect the insertion site, and prevent infection. In this blog post, we will explore the advantages and disadvantages of relevant peripheral IV cannula dressings commonly used in healthcare settings.

Advantages of Peripheral IV Cannula Dressings

1. Secure Adhesion

One of the primary advantages of using peripheral IV cannula dressings is their ability to provide secure adhesion. These dressings are designed with adhesive properties that allow them to stick firmly to the skin, ensuring the cannula remains in place during patient movement and minimizing the risk of accidental dislodgement.

2. Breathability

Many peripheral IV cannula dressings are made from breathable materials, such as porous films or non-woven fabrics. This allows air to circulate freely around the insertion site, reducing the risk of moisture buildup and promoting optimal wound healing conditions.

3. Transparent Design

Some peripheral IV cannula dressings come in transparent designs, allowing healthcare professionals to easily monitor the insertion site without removing the dressing. This transparency enables early detection of potential complications, such as inflammation or infection, and facilitates timely intervention.

4. Water-Resistant

Certain peripheral IV cannula dressings are water-resistant, meaning they can withstand exposure to water or other liquids without compromising their adhesive properties. This feature allows patients to safely shower or bathe without the need for frequent dressing changes, improving convenience and maintaining site integrity.

Disadvantages of Peripheral IV Cannula Dressings

1. Skin Irritation

One of the potential disadvantages of peripheral IV cannula dressings is the risk of skin irritation. Certain individuals may have sensitivity or allergic reactions to the adhesive components or materials used in the dressings, leading to itching, redness, or rash formation. It is essential to have alternative options available for such patients.

2. Infection Risk

While peripheral IV cannula dressings are primarily designed to reduce the risk of infection, improper application or inadequate hygiene practices can still pose a risk. If the dressing is not changed as per protocol or if the insertion site is not adequately cleaned before re-dressing, bacteria or other pathogens may thrive, increasing the chances of an infection.

3. Limited Lifespan

Peripheral IV cannula dressings usually have a limited lifespan. Over time, due to factors such as moisture, movement, or natural wear and tear, the adhesion of the dressing may decrease, compromising its effectiveness. Regular assessment and timely dressing changes are necessary to ensure optimal adhesion and site protection.


Peripheral IV cannula dressings provide various advantages, including secure adhesion, breathability, transparent designs, and water-resistance. However, they are not without disadvantages, such as the risk of skin irritation, potential for infection if not properly managed, and their limited lifespan. To ensure the appropriate use of peripheral IV cannula dressings, healthcare professionals should carefully assess patient needs, consider individual sensitivities, follow best practices for aseptic technique, and monitor dressing effectiveness regularly.
