Commonly Used Wound Dressings

 

 

Gauze dressings
Gauze dressings are a type of traditional wound dressing made of woven cotton or synthetic fibers. They are versatile, inexpensive, and readily available, making them a popular choice for wound care. They can be used alone or in combination with other dressings to absorb wound exudate (the liquid secreted by wounds during the healing process, otherwise known as pus) and provide a protective barrier to the wound bed. However, they are not suitable for several types of serious wounds, as they can dry out and stick to the area, causing trauma and delaying the healing process.

 

Non-adherent dressings
Non-adherent dressings are designed to minimize trauma and pain during dressing changes. They are made of materials that don’t stick to the wound, such as silicone or low-adherent fabrics. These types of dressings can be used for wounds with delicate or fragile tissue, such as burns, skin grafts, and donor sites. However, they may not be suitable for heavily exudating wounds or infected wounds, as they can create a warm and moist environment that encourages bacterial growth.

 

Hydrocolloid dressings
Hydrocolloid dressings are absorbent pads with a strong adhesive back, often used for low to moderate exudating wounds. The gel-forming agents in these dressings are highly absorbent and help keep the area moist. They help protect the wound from contamination, reduce pain, and promote wound healing.

 

Foam dressings
Often made from polyurethane foam, foam dressings are often used for moderate to severe wounds. These dressings have a soft, cushioning effect and absorb a large amount of wound exudate, which helps reduce the risk of maceration.

 

Alginate dressings
Alginate dressings are made from seaweed and contain calcium and sodium ions that create a gel-like substance when in contact with a wound.

 

Transparent film dressings
Transparent film dressings are thin, transparent, and waterproof, allowing for wound observation without removing the dressing. They are often made from polymer membranes that allow oxygen to reach the wound while vapor is released. Transparent film dressings can help reduce pain and protect the wound from contaminants while it’s healing.

 

Hydrogel dressings
Hydrogel dressings are composed of water or glycerin and create a moist wound environment conducive to wound healing. Hydrogel dressings are a common choice for dry wounds with minimal drainage, as they can help prevent desiccation, promote autolysis, and reduce wound pain.

 

Collagen dressings
This type of wound dressing contains collagen, a protein found in the human body that facilitates healing. These dressings can be derived from animal or human sources, and are available in various forms, including gels, powders, and sheets. Collagen wound dressings can help reduce inflammation, and provide a protective barrier around the wound. However, they may not be suitable for wounds with excessive exudate, as they can become saturated and lose their effectiveness. Additionally, collagen wound dressings may not be appropriate for individuals with allergies to collagen or other animal-derived products.

 

Silver dressings
Silver wound dressings contain silver, a natural antimicrobial agent that can help prevent and treat wound infections. These dressings may contain silver in various forms, including ions, particles, or compounds, and are available in different applications, such as gels, foams, and films. While effective in some cases, prolonged use of silver wound dressings may lead to silver toxicity, which can cause skin discoloration, impaired wound healing, and other adverse effects. As such, it is important to use silver wound dressings under the guidance of a healthcare professional or wound care specialist.

 

Composites dressings
Composites wound dressings are a type of dressing that combines different materials, such as foam, hydrocolloid, and alginate, into a single dressing. These dressings are designed to provide a combination of benefits, such as absorption, moisture control, and protection, and are often used in the management of complex wounds. Composites wound dressings are particularly useful for wounds with multiple stages of healing, or for wounds that have different needs at different stages of healing. They may also be used to manage wounds with complex drainage patterns, such as fistulas or sinuses.

There are various dressing categories to choose from, and clinicians should remember that although dressings are categorized, specific product features, benefits, and dressing technology may vary. Clinicians should have practical knowledge of dressing categories, wound types, and indications when deciding on the most appropriate dressing for best healing outcomes. Clinicians tend to learn the dressing’s brand name in their facility’s formulary and not know what the dressing’s function is.

 

Wound care documentation should support the medical necessity for advanced wound care dressings. Supporting documentation includes wound date of onset, wound etiology, wound status, wound size, wound depth, presence of bioburden, exudate type and amount, dressing frequency, and physician wound progress notes. Clinicians should be familiar with the payment systems, which may vary by health care setting, state, and region. When selecting a dressing, remember to consider wound size and depth, exudate amount, dressing frequency, and any patient-related factors such as payer source and who will be changing the dressing.

 

Dressings should have conformability to keep direct contact with the wound bed. Wounds located on the heel are a good example; you may need to create a heel cup or use a heel-designed dressing to avoid bulkiness. Remember always to pack dead space in wounds, but loosely. Wound cleansing during each dressing change will help decontaminate the wound, eradicate biofilm, and promote healing.

 

Cleansing the wound bed surface, periwound, and surrounding skin will support good wound hygiene practices. There are various wound cleansers and solutions, but become familiar with the ingredients in products. Cleanser and solution features may include bactericidal, bacteriostatic, fungicidal, various delivery methods (spray, non-aerosol, splash guard), and specific dosing (vials, units). Consider the cleanser or solution’s mode of action paired with the type of dressing and format to avoid deactivation of certain bioactive products. Using dressings that keep the wound warm and maintain an optimal moist wound environment will prevent moisture imbalance and promote healing.

 

Some dressings contain super absorbent polymers that have a moisture transfer and wicking property to ensure periwound protection from excess moisture. Selecting the appropriate dressing size will help prevent maceration and further skin impairments.

 

Remember the periwound is just as important as the wound. Use liquid skin protectants or sealants and barrier cream to protect surrounding skin from moisture-associated skin damage. In wounds that are draining only a scant amount of exudate, you can stretch the dressing wear time or may need to use a dressing to donate moisture. This will help optimize a moist healing wound environment, thereby moving the wound toward a healing trajectory. Remember to keep wounds covered because research shows that wounds heal at a faster rate when the wound is covered and maintain a steady temperature.

 

Types Of Wound Dressings & When To Use Them
 

Gauze Sponge
Made from 100% cotton, gauze sponges absorb drainage such as blood or other fluids making them a good, all-purpose wound dressing whether you need to clean, dress, pack, or prep a wound. This option is also economical.

 

Gauze Bandage Roll
Gauze bandage rolls are made from 100% cotton and can be used as a first layer dressing or as an added layer of protection. This type of wound dressing is perfect for wounds on limbs or on the head, as well as wounds that are difficult to dress.

 

Non-Adherent Pads
This type of wound dressing protects wounds without sticking to the wound itself. It’s an easy, all-in-one dressing that can be placed over any minimally draining wound.

 

Non-Adherent Wet Dressings
These dressings are ideal as a primary layer to keep the wound bed moist, which helps to promote cell migration. Non-adherent wet dressings conform to the wound without sticking to the surface.

 

Foam Dressings
Foam dressings are ultra-soft and highly absorbent thanks to the foam material they are comprised of. This type of wound dressing helps to cushion and protect the wound while maintaining a healthy level of moisture.

 

Calcium Alginates
This type of wound dressing is highly absorbent and can hold as much as 20 times its weight in moisture. It is especially useful in wicking moisture out of deep tunneling areas of a wound.

 

Hydrogel Dressings
Hydrogel dressings lend moisture to a wound which can help break down dry and dead tissue. Keeping the wound moisturized helps to promote cell growth.

 

Transparent Dressings
Transparent dressings allow the transfer of moisture while offering a great securement layer as well as visualization of the wound. This is a great option for covering an IV.

 

Alcohol Preps
Alcohol preps aren’t a type of wound dressing but are necessary when preparing to dress a wound.

Benefits Of Gauze Wound Dressings

Cost-effectiveness: When less frequent dressing changes are required, gauze dressings are found to be the least expensive dressing method available. However, their cost-effectiveness should be put into perspective by considering other factors. These include frequency of dressing change, wound healing time, patient discomfort, and the need for dedicated nursing.

 

Ease of use: As gauze wound dressings are one of the oldest dressing materials available, the majority of healthcare providers are familiar with its use. Gauze wound dressings remain popular because of their ease of use. They can be packed into areas which might be inaccessible to other wound dressing types. For instance, they can be used for packing tunnels and sinus tracts.

 

Versatile: Gauze wound dressings are available in a variety of shapes and sizes. Some of their forms include rolls, strips, ribbons, and pads.

 

 

Application Of Gauze Wound Dressings

Secondary dressing: Even though they were traditionally used as primary dressings, gauze wound dressings are now preferred to be used as secondary dressings.

 

Wound cleansing: Gauze wound dressings are suitable for use in wound cleansing, scrubbing, and local hygiene care of surgical or non-surgical wounds.

 

Homeostasis: Gauze dressings are effective in achieving homeostasis and can be used for bandaging.

Limitations Of Gauze Wound Dressings

 

 

Gauze wound dressings are unable to maintain a moist wound environment which is considered a prerequisite for normal wound healing. They might dry up the wound leading to eschar formation.

 

Gauze wound dressings are unable to provide an effective barrier against the entry of bacteria into the wound. As a result, gauze wound dressings are associated with a 50% greater chance of infection as compared to semi-occlusive dressings.

 

Gauze wound dressings tend to adhere to the wound surface. This leads to painful removal and patient discomfort.

 

As gauze wound dressings are not able to appropriately handle the wound exudate, they require frequent dressing changes. This is associated with an increased need for nursing care, patient dissatisfaction, and increased costs in the long run.

FAQ
 
 

Q: How many days should a wound dressing stay on?

A: They can be left in place for up to 4–7 days, but should be changed once saturated with exudates. Their composition makes them atraumatic upon removal. If changed daily, they can also be used on infected wounds.

Q: What happens if you leave a wound dressing on too long?

A: If the bandage is left on for too long, the healing process will be disrupted, and the propensity for infections dramatically increases. Improper wound care can result in the skin coming into contact with moisture for too long, ultimately resulting in macerated skin.

Q: What is the correct order for changing a wound dressing?

A: Use new disposable gloves.
If you are using lukewarm water, wet the gauze. Clean the surrounding skin first.
Then take a new gauze and clean the wound. Clean from inside to out.
When out of the shower, pat dry the surrounding skin carefully with gauze and put them into the bag.

Q: Can you change a wound dressing too much?

A: It is acceptable to do more frequent dressing changes during the inflammatory phase, but the impetus needs to be decreasing this phase to as short a period of time as possible. When choosing wound dressing change frequency to support optimal healing, the motto of “less is more” should be our modus operandi.

Q: Should wound dressing be tight or loose?

A: Hold the dressing in place by wrapping a sterile gauze roll over the dressings (Picture 4). Start wrapping the limb from the place farthest away from the body. Secure the wrap with tape. Do not wrap or tape the wrap too tightly because this can reduce blood flow to the limb.

Q: What precautions should be taken when changing dressings?

A: Follow these steps to remove your dressing:
Wash your hands thoroughly with soap and warm water before and after each dressing change.
Put on a pair of non-sterile gloves.
Carefully remove the tape.
Remove the old dressing.
Remove the gauze pads or packing tape from inside your wound.

Q: What is the best dressing for a granulating wound?

A: SUPERFICIAL GRANULATING WOUND WITH HIGH EXUDATE
Use alginate dressings, or hydroactive dressings, or foam dressings. Cover with a non-adherent high absorbent dressing. Alginate alternative dressing may also be used with a foam dressing. AIM: Clear infection, reduce odour, absorb exudate, protect.

Q: What PPE should be worn when changing a wound dressing?

A: Wear gloves during all stages of wound care including when applying new dressings. Don gloves after preforming hand hygiene. During an individual resident's wound care, doff gloves every time when going from dirty to clean surfaces or supplies.

Q: How long can a wound dressing stay on?

A: The original dressing should be left in place for up to two days (or as advised by the nurse or doctor), provided it is not oozing. The wound must be kept dry for two days. If the dressing becomes wet from blood or any other liquid, it must be changed.

Q: What is the correct order for changing a wound dressing?

A: Changing your dressing is a simple process and follows the same few steps every time:
Wash your hands.
Put on Clean gloves.
Remove the old dressing and dispose of it.
Clean the wound.
Wash your hands.
Put on clean gloves (sterile gloves are not needed)
Apply the new dressing and secure it in place.

Q: What are the requirements for wound dressing?

A: Renewable supplies
Sterile compresses.
Non-sterile disposable gloves.
Adhesive tape and/or crepe or gauze bandage.
Sterile 0.9% sodium chloride or sterile water.
Depending on the wound: antiseptic (7.5% povidone iodine scrub solution, 10% povidone iodine dermal solution), paraffin compresses, analgesics.

Q: How many layers of dressing do you need for a wound?

A: These goals can be accomplished with a layered dressing comprised of a bottom, nonadherent contact layer, a middle layer that can absorb wound exudate and exert pressure, and an outer covering of tape or a rolled bandage. Sterile dressings come in various sizes from simple gauze pads to adhesive bandages.

Q: What are three types of wound dressings?

A: Further information about specific dressings' indications may be accessible on the manufacturer's website or from a sales representative.
Gauze: Moistened gauze provides mechanical debridement when removed.
Films: Films are thin and transparent dressings.
Foams.

Q: What are 3 reasons for dressings to be applied on a wound?

A: There are three fundamental principles to wound dressing that make it an essential part of wound management.
Provide a temporary physical protective barrier.
Absorb exudate from the wound.
Provide an optimal environment for re-epithelialization (the growth of new, healthy skin tissue).

Q: What are the benefits of wound care?

A: Without the proper care and healing, a wound can lead to further health issues or even amputation. A clinical approach to wound care can speed healing, increase comfort and help people get back to their normal lives.

Q: How long should you keep a dressing on a wound?

A: Changing the dressing
The original dressing should be left in place for up to two days (or as advised by the nurse or doctor), provided it is not oozing. The wound must be kept dry for two days. If the dressing becomes wet from blood or any other liquid, it must be changed.

Q: What are the advantages and disadvantages of wound dressing?

A: Advantages: These include absorbing water and providing a cooling effect, which can reduce pain. Hydrogels are generally transparent or clear. They provide a moist environment, which encourages autolytic debridement.

Q: What are the risks of wound dressing?

A: Dressing changes are associated with a risk of infection: the more often a dressing is changed, the more the wound is exposed to contamination. Poor exudate management is also a risk factor. Wound exudates contain material derived from contaminating microorganisms.

Q: Can you leave a wound dressing on for 2 days?

A: Changing the dressing
The original dressing should be left in place for at least two days (48 hours) (or as advised by the nurse / doctor), provided that the wound is not oozing. The wound must be kept dry. If the dressing becomes wet from blood or any other liquid it must be changed.

Q: Why is my dressing sticking to my wound?

A: Check that it's safe to use the product directly on your wound is safe before applying it. Another reason a dressing keeps sticking to a wound is that it needs to be changed more frequently. Ensure you check the dressing regularly and apply a fresh one when needed.
