2.  A dressing is a sterile pad or compress
applied to a wound to promote healing
and protect the wound from further
harm. A dressing is designed to be in
direct contact with the wound, as
distinguished from a bandage, which is
most often used to hold a dressing in
place. Many modern dressings are self-
adhesive.

3.  There are 9 types of dressing…..
1.Gauze
2.Transparent Films
3.Hydrogels
4.Foams
5.Hydrocolloids
6.Calcium Alginates
7.Composites
8.Collagen
9.Silicone

4.  Gauze, or cloth dressings, are the most commonly used and readily
available wound dressings out there today. They can be made from woven
or nonwoven silk, linen, polyester, rayon, or cotton causing them to be
highly permeable. This type of material is non-occlusive meaning it does not
seal on the skin, allowing blood, water, and air to easily pass through. This
dressing easily helps the wound dry out, minimizing exudate, the fluid
leaking from the wound.
 Gauze can come in many different shapes and sizes that can be easily
adapted to fit the wound. There are sterile and non-sterile varieties. There
are also those with or without an adhesive border. You can use it on
anything from a small finger injury to a wound that extends across the
body.
• 1.Gauze sponge: This type of gauze is typically made from 100% cotton,
and is commonly used to absorb blood or other fluids.
• 2.Gauze bandage roll: Also used for all types of wounds, the gauze
roll can be used as a first layer or added layer on a wound. The 100% cotton
roll can be wrapped around limbs on the head and is especially useful for

5.  Transparent film dressings are clear
polyurethane thin sheets that have an
adhesive coating on one side that sticks to the
skin. The coating sticks to the skin around
the injury which is dry but does not adhere to
the wound itself due to its reaction with the
wound exudate.
 Transparent dressings can be used as either a
first or second securement layer on the injury.
This is a commonly used dressing that a
doctor will apply when they want to keep
track of a wound.

6.  Hydrogels are meant to soothe wounds, reduce pain, help
heal, and fight infection. This wound dressing is made of 80
to 99% water or glycerin, adding moisture to dry wounds.
By adding moisture to the area, Hydrogels enable faster
healing by breaking down tissue that is dry and dead and
promoting cell growth.
 Hydrogels are best used for dry wounds that need to heal,
as well as those with eschar. It is best used for those
injuries which have little to no fluid excreted. It is also
helpful to use hydrogels for wounds that are especially
painful.

7.  Another common type of dressing is foam dressings. Foams are made of
foamed polymer, usually polyurethane, and made into sheets or other
shapes. They have open cells which can hold fluids, enabling
absorbency. But the extent of absorbency is based on the thickness and
composition of the foams. Foams absorb the excess fluids as well as
keep the area moist at the same time, allowing for faster healing as
well. The ultra-soft nature of the material also helps cushion the injury,
protecting it from further harm.
 These dressings can sometimes come pre-soaked in solutions, or
combined with other materials. They can easily be removed because
the contact with the wound is non-adhesive.
 Best Uses: Foams help prevent bad odors, as well as moderate to heavy
discharge. They are ideal for both partially-thick and full-thickness
wounds, and both serious and unserious wounds. You can also use
foams for pressure injuries.

8.  Hydrocolloid dressings are made up of hydrophilic colloidal
particles. These can include gelatin, pectin, and cellulose.
These materials allow for flexibility, which means greater
comfort for all skin types. The wound dressings have secure
backings made up of a film or foam self-adhesive, making
them non-breathable, not to mention easy to apply. By
creating a sealed, moist wound environment, hydrocolloids
can keep the wound clean, prevent infection, and speed up
the healing process.
 Best Uses: You can use hydrocolloids for burns, necrotic
injuries, with compression wraps, wounds with light to
moderate drainage, and on venous or pressure ulcers. They
are effective for autolytic debridement.

9.  This type of dressing is made of brown seaweed fibers and sodium, making
them biodegradable. Calcium alginates can absorb up to twenty times its
weight. This high absorbency makes it ideal for sucking out the moisture from
a deeply tunneled wound. Like hydrocolloids, alginates react with the
exudate, creating a gel-like substance which enables the injury to heal
quicker. You can find alginates in three varieties:
 Sheets: These may be put on the wound bed to absorb the draining fluids.
 Ropes: This variety tightly fills tunnels or areas under the skin which have
become eroded, i.e. areas of undermining.
 Applicators: With tips of alginate, applicators are used to probe the lesion,
occupy cavities and tunnels, to obtain swab cultures, and to measure the
depth of the wound.
 Best Uses: These macroalgae can be very absorbent, which makes it perfect
for those wet injuries which have a lot of drainages. This means extreme or
deep wounds, including burns, packing wounds, venous ulcers, or higher-state
pressure ulcers. Alginate dressings need to be changed often due to the
amount of fluid they will absorb.

10.  Composite dressings, also known as combination dressings, are multi-layered.
They can be used as either the primary dressing or secondary dressing. Typically
the composite dressing consists of three layers:
 Inner layer: The contact layer is non-adherent, which keeps the injury safe
during dressing changes.
 Middle layer: This layer is absorptive, taking away moisture from the wound to
avoid maceration, but still keeping the environment hydrated. This layer can be
made of alginate, hydrogel, semi-permeable foam, or hydrocolloid.
 Outer layer: A barrier for bacteria, this protective outer layer is imperative for the
prevention of infection. It is often made of a semi-permeable film.
 Best Uses: These dressings don’t have as many uses as many other types, due to
their prepackaged nature. However, they can be used on light to heavy wounds.
Be extra careful if you have dry or sensitive skin. Check with the manufacturer to
be sure the composite dressing can be used on an infected wound site.

11.  Collagen dressings are a bit different than most other dressings
because they act as a temporary second skin. Having this second
skin enables new cells to accumulate, grow, and become
sustainable. Without such a dressing, the amount of time that the
wound would heal would take much more time. Not only that, but
collagen helps with the removal of dead tissue, the formation of new
blood vessels, and the tightening of the edges of the site.
 Best Uses: Collagen dressings are mostly used for chronic wounds
that have a very slow or completely stalled rate of healing. You can
use them on transplant sites, pressure sores, burns, ulcers, surgical
sites, or large surface area injuries.

12.  Silicone is a common synthetic polymer that has a lot of applications in this day and age. In
dressing form, soft silicone is tacky, allowing it to form a tight seal that repels water. The
tackiness of the silicone allows it to be reapplied several times without losing its adhesion. It
will not stick to the wound though, and will not create further damage. Additionally, silicone
has anti-bacterial properties and is adhesive to even fragile or dry skin.
 Silicone dressings are comfortable, and reduce pain and trauma in injuries during the
changing of dressings. It doesn’t leave a residue, making it easy to work with. Though they can
be helpful in wound dressing, they can be expensive.
 Best Uses: Topical silicone gel sheets are said to prevent keloids or excessive scar tissue. This
happens through the prevention of moisture penetrating the wound. With less moisture, there
is less blood flow and therefore less collagen in the area. Since collagen is the material scars
are made of, the absences of it will cause the skin to be paler, making the scar less apparent.
