Dress dressing is a sterile pad or compress applied to the wound to speed healing and protect the wound from further damage. Dressings are designed to be in direct contact with the wound, which is distinguished from the bandages, which are most often used to hold the clothes in place. Many modern makeup are self-adhesive.

Medical use
Dressings can have a number of purposes, depending on the type, severity and position of the wound, although all goals are focused on improving recovery and protecting from further damage. The main purpose of dress is:
- Bleeding stems - to help cover the wound to speed up the clotting process;
- Protection from infections - to sustain wounds against germs and mechanical damage;
- Absorb the exudate - to absorb blood, plasma, and other fluids that come out of the wound, contain it in one place and prevent maceration;
- Relieve pain - either with analgesic effects, compression or simply prevent the pain from further trauma;
- Debit wounds - to remove a foreign object from a wound to speed healing;
- Reduces psychological pressure - to obscure healing wounds from the view of the patient and others.
Ultimately, the purpose of dressing is to promote wound healing by providing a sterile, breathable and humid environment that facilitates granulation and epithelization. This will then reduce the risk of infection, help heal wounds faster, and reduce scarring.

Type
Historically, bandages were made of a piece of material, usually cloth, but the use of cobwebs, dirt, leaves and honey has also been described.
However, modern clothing includes dry or impregnated gauze, plastic films, gels, foams, hydrocolloids, alginates, hydrogels, and polysaccharide pastes, granules and beads. They all provide different physical environments that are suitable for various cuts:
- The absorption of exudates, to regulate moisture levels around the wound - for example, dry gauze absorbs exudates strongly, drains wounds, hydrocolloids maintain a moist environment, and film dressings do not absorb exudate;
- Gas permeability and exchange, especially with respect to oxygen and water vapor;
- Maintains optimum temperatures to promote healing;
- Mechanical mechanically registers wounds to remove swamps.
- Pressure dressings are commonly used to treat burns and after skin grafts. They apply pressure and prevent fluid from collecting in tissues.
Dressings can also regulate the wound chemical environment, usually with the aim of preventing infection by impregnation of topical antiseptic chemicals. Commonly used antiseptics include povidone-iodine, boracic fabric or castor oil gauze historically. Antibiotics are also often used with dressings to prevent bacterial infections. Medical grade honey is another antiseptic choice, and there is moderate evidence that honey dressing is more effective than antiseptics and common screening for healing postoperative wounds infected. Bioelectric dressings can be effective in attacking certain antibiotic-resistant bacteria and accelerate the healing process.
Dressings are also often impregnated with analgesics to relieve pain.
The physical features of the sauce may affect the effectiveness of the topical medication. Occlusive dressings, made of moisture-proof substances such as plastic or latex, can be used to increase the rate of absorption to the skin.
Dressing is usually guaranteed with adhesive tape and/or bandages. Many bandages are currently produced as "islands" surrounded by adhesives, ready for immediate application - these are known as island clothes.
Passive products
Generally, these products are indicated only for superficial, clean, and dry wounds with minimal exudate. They can also be used as a secondary dressing (additional dressings to secure the main dressing in place or to absorb additional fluid from the wound). Examples: Gauze, fibers, adhesive bandages (plaster), and cotton. The ultimate goal is to protect the wound from bacterial contamination. They are also used for secondary clothing. Gauze dressing consists of woven or non-woven fibers of cotton, rayon, and polyester. Gauze dressings are able to absorb fluid from wounds but often change. Excessive wound removal will cause the gauze to attach to the wound, causing pain when trying to remove the gauze from the wound. Bandages consist of cotton, cellulose, or polyamide. Cotton bandages may serve as a secondary dressing while compression bandages provide good compression for venous ulcers. On the other hand, tulle gras sauce impregnated with paraffin oil is indicated for superficial wounds.
Interactive products
Some types of interactive products are: semi-permeable film dressings, semi-permeable foam dressings, hydrogel dressings, hydrocolloid dressings, and alginate dressings. In addition to preventing bacterial contamination from wounds, they keep the wound environment humid to promote healing.
Semi-permeable film set - This makeup is a transparent film made of polyurethane. This allows the movement of water vapor, oxygen, and carbon dioxide into and out of bandages. It also plays an additional role in autolytic debridement (removal of dead tissue) which is less painful when compared to manual debridement inside the operating room. It is very elastic and flexible, so tightly attached to the skin. Because the bandages are transparent, wound inspection is possible without removing the bandages. Due to limited absorption capacity, such clothing is only used in shallow wounds with low amounts of waste.
Semi-permeable foam coloring - This sauce is made of foam with hydrophilic properties (attracted to water) and an outer layer of hydrophobic (water-rejected) properties with adhesive boundaries. The hydrophobic layer protects the wound from contamination of the outer liquid. Meanwhile, the inner hydrophilic layer is able to absorb a small amount of fluid from the wound. Therefore, this type of pads is useful for wounds with high discharge counts and for wounds with granulation tissue. Secondary dressing is not required. However, it needs frequent change and is not suitable for dry wounds. Silicon is a common material that forms foam. Foam is able to shape according to the shape of the wound.
Hydrogel Dress - This dressing is made from synthetic polymers such as methacrylate and polyvinyl pyrrolidine. It has a high water content, thus providing moisture and cooling effects for wounds. Dressing is easy to remove from the wound without causing damage. Dressing also does not cause irritation. Therefore, it is used for dry necrotic wounds, necrotic wounds, pressure ulcers, and burns. Not suitable for injuries with heavy feces and infected wounds.
Dress hydrocolloid - This type of dressing contains two layers: the inner colloid layer and the waterproof outer layer. It contains gelling agents such as carboxymethylcellulose, gelatin and pectin. When the pads come into contact with the wound, the wound fluid is maintained to form a gel that provides a moist environment for wound healing. It protects wounds from bacterial contamination, absorbs wounds, and digests necrotic tissue. It is mostly used as secondary clothing. However, it is not used in wounds with high discharge and neuropathic ulcers.
Alginate sauce - This type of sauce consists of a sodium or calcium salt of alginic acid. This dressing can absorb a lot of fluid from the wound. The ions in the dressing can interact with the blood to produce a film that protects the wound from bacterial contamination. However, the dressing is not suitable for dry wounds, third-degree burns, and deep wounds with open bones. It also requires secondary clothing because the wound can quickly dry with alginate dressing.
Bioactive Products
Progress in understanding injuries has ordered biomedical innovations in the treatment of acute, chronic, and other types of injuries. Many biologists, skin substitutes, biomembranes and scaffolds have been developed to facilitate wound healing through various mechanisms.
Use of dressing
Applying sauce is a first aid skill, although many people do the exercises without training - especially on minor injuries. Modern dressings will almost all be wrapped in a sterile wrapper, dates encoded to ensure infertility. Sterility is necessary to prevent infection of the population pathogens in the sauce.
Historically, and still the case in many less developed areas and in emergencies, bandages are often improvised as needed. It can consist of anything, including clothing or spare material, which will satisfy some basic dressing principles - usually stemming bleeding and absorbing exudates.
Applying and replacing dressings is one of the common tasks in nursing.
