Types of wound dressings pdf

Use hydrogels to maintain a moist wound environment on a clean, healthy, Foam dressings granulating wound and to facilitate autolytic debridement in Foam dressings are semipermeable and either hydrophilic or wounds with necrotic tissue such as slough or eschar. Hydrogels hydrophobic with a bacterial barrier. They are either poly- can be used on pressure ulcers, skin tears, surgical wounds, and urethane or silicone-based and are capable of handling moderate burns, including radiation oncology burns and are safe on to high volumes of wound exudate.

They provide thermal neonatal skin. These dressings are suitable for wounds with insulation to the wound, create a moist wound environment, are minimal to moderate exudate.

Hydrogel dressings are commonly non-adherent, and allow atraumatic dressing removal. Foam available in three forms: amorphous gel, impregnated-gauze, and dressings may also be used as the secondary dressing with sheet hydrogel and can be useful when managing painful hydrogel or alginate dressings and may be used in conjunction wounds. Hydrogel dressings that act as a release platform have also Foam dressings may be manufactured with an adhesive been developed containing hyaluronic acid, antimicrobials and border, which eliminates the need for a securing device or antibiotics.

Oxyzyme for example is a two component hydrogel without an adhesive boarder. Shaped versions of these dressings dressing which releases both oxygen and iodine into the wound are also available Heel and Sacrum. Foam dressings are also and is suitable for non-infected moderately exudating wounds. Hydrocolloid dressings Hydrocolloid dressings consist of absorptive ingredients typi- Antimicrobial dressings cally carboxymethylcellulose, pectin or gelatine. Like hydrogels, When using antimicrobials the objective must always be to hydrocolloids can absorb minimal to moderate amounts of provide optimum conditions to support rapid healing.

In selecting antimicrobial agents to reduce or not allow water, oxygen, or bacteria into the wound. This may eradicate micro-organisms, choice must be influenced by the help facilitate angiogenesis and granulation. Hydrocolloids also specificity and efficacy of the agent, its cytotoxicity to human cause the pH of the wound surface to drop; the acidic environ- cells, its potential to select resistant strains and its allergenicity.

The range of topical antimicrobial agents currently used includes Like hydrogels, hydrocolloids can help a wound to granulate products containing iodine cadexomer iodine and povidone or epithelialize and encourage autolytic debridement in wounds iodine , products containing silver silver sulfadiazine and ionic with necrotic or sloughy tissue present. However, because of silver-impregnated dressings and products containing antiseptic their occlusive nature, hydrocolloids should not be used if the agents such as polyhexamine.

Honey is also antimicrobial, acting wound or surrounding skin is infected and are not recommended as a debriding agent and can help with odour control.

Bleeding can be a problem in patients with clotting be reassessed and alternative treatments considered. Larval therapy Biosurgery with the larvae of Lucilia sericata Green Bottle are a Detecting and modifying inflammation proven method of wound debridement, which also reduce mi- crobial load and stimulating healing. They may also encourage One reason for delayed wound healing is a persistent destructive wound bed revascularization.

To be most effective hard eschar inflammatory response within the wound with elevated levels of should first be softened or excised by sharp debridement. Larvae proteases destroying attempts to establish a new extracellular are intolerant of excessive exudate. Larval therapy usually con- matrix. Larval therapy can modulating dressings are available, the majority derived from cause discomfort and is contraindicated in patients with a freeze dried, oxidized cellulose and bovine collagen, designed to bleeding disorder and should be used with caution when applied reduce MMP activity and enhance growth factor availability.

These products may contain an antimicrobial such as silver and when used on appropriate wounds have been found to aid healing. Deodorizing dressings Topical agents such as steroids may also be applied to the Wound odour can be a significant problem for patients, partic- wound, especially those with an identified inflammatory cause ularly those with non-healing or malignant wounds. Charcoal- such as pyoderma gangrenosum, and the peri-wound skin.

When based products can be effective in reducing wound odour. Clin- used steroid application should be time restricted but they may isorb uses activated charcoal to absorb odour and is designed to be of value in reducing exudate and can reduce wound pain.

A Similarly topical analgesics such as EMLA cream can be of value range of other composite dressings containing activated charcoal as a wound dressing when wound pain is an issue.

Transparent dressings are useful for when medical professionals or carers want to monitor wound healing, as these dressings cover the wound with a clear film. These make identifying potential complications much easier, such as by making infections easier to spot at an earlier time.

For this reason, these kinds of dressings are often used on surgical incision sites, on burns and ulcers, and on IV sites. These dressings are breathable but impermeable to bacteria, helping to keep the wound clean and dry, preventing infection and speeding up healing.

They are also flexible, which makes them comfortable to wear. See Transparent Dressing Products. Cloth dressings are the most commonly used dressings, often used to protect open wounds or areas of broken skin. They are suitable for minor injuries such as grazes, cuts or areas of delicate skin. These dressings come in all shapes and sizes, from small coverings for fingers to larger ones for wounds across wider areas of the body.

As well as pre-cut dressings, these also come in a roll option that is made to be cut to size. See Cloth Dressing Products. Take a look at our extensive range - browse through now by clicking the following button. Contact layers con-.

An understanding of wound pathophysiology, a defined treatment goal and regular wound assessment combined with knowledge of basic wound dressing categories will provide guidance on product selection for different clinical situations and wound types. Is necrotic If the wound bed is dry, the dressing will not form gel and may adhere to tissue, causing trauma.

This dressing, when used in large wounds, may dehydrate the wound. Nearly everyone will experience an open wound at some point in their lives. Wound Care No further dressings are needed, if only to protect the site from recurrent injury or to further try to reduce scarring.

The first three phases of healing are usually short but scar maturation may take a few months. Wound healing by secondary intention occurs when the edges of a wound cannot be approximated,.

It is a complex biological process [1]. On the opposite end of the spectrum, we have alginate dressings. Alginate dressings are extremely absorbent and are used on wounds that have excessive drainage. Along with absorbency, alginate dressings also create a gel-like substance to help with the healing process. Alginate should only be used on wounds that are wet with large amounts of liquid drainage 2.

Since alginate dressings are used on wounds with a lot of fluid, they need to be changed more often—every two days at the very least. When these types of dressings are changed too frequently, there is a bigger chance for excessive dryness and bacterial penetration.

Finally, there are collagen wound dressings. These types of dressings are most commonly used for chronic wounds with a slow or stalled healing time. They are also be used on pressure sores, transplant sites, surgical wounds, ulcers, burns, or injuries that cover a large area of your body 2. Without it, the healing time would take much longer. Collagen dressings are a good alternative to traditional bandaging because they help to promote healing in a number of different ways.

In addition to the common types of wound dressings, there are a number of other options available. Nothing beats a professional medical opinion.

The best way to be ready is to have a good supply of wound care supplies and any wound dressings you may need. Byram Healthcare is a leading wound care supplier with an outstanding Chronic Wound Program.
