Wound healing process
The principle of the old wound healing process is to keep the wound dry in order to heal. Recent research has proven otherwise, dry wounds can hinder wound healing. In addition, a wound that is too wet can also cause maceration of the skin around the wound.
The most effective wound healing principle that is widely applied today is the principle of moisture balance or moisture balance. The technique of applying this principle is also known as modern dressing.
Modern dressings have been shown to facilitate the action of cytokines and chemokines on wounds. Both of these molecules function to trigger cell growth and stabilize the wound tissue matrix.
The basic difference between the new and old methods is the way the wound is wrapped. The old method required covering the wound with dry gauze and changing it regularly. While the new method is to apply a material, such as a hydrogel, to keep the wound moist.
The following are various wound medicines in pharmacies according to modern wound dressing principles:
1. Hydrogel
Hydrogels are drugs that are based on glycerin or water. This drug is good for helping to soften the dead tissue that is black or yellow in color which is usually at the edges of the wound. This tissue must be removed because it can inhibit the wound to heal quickly and dry.
2. Film dressing
This type is usually used as a secondary wound medicine. The film dressing is made of polyurethane film and has an adhesive. This layer is often used to close wounds after surgery.
3. Hydrocolloid
Hydrocolloid functions to maintain wound moisture while preventing the wound from becoming infected. Hydrocolloids are made of pectin, gelatin, carboxy-methylcellulose, and elastomers. Hydrocolloids can be used for open wounds and wounds with minor infections.
4. Calcium alginate
Calcium alginate is made from seaweed and will turn into a gel when mixed with wound fluid. Calcium alginate is great for wounds with mild to severe infections because it can absorb excess wound fluid and promote wound healing.
5. Topical antibiotics
One of the widely used topical antibiotics contains 1.2 percent silver and hydrofiber. This drug works against broad-spectrum bacteria so it can be used for chronic wounds and wounds that are at risk of infection. However, this drug should not be used for a long time.
6. Foam dressing
Foam dressings are especially useful in large infected wounds with large amounts of pus. This material is able to absorb a lot of wound fluid due to infection so that it can make the wound dry quickly.
7. Povidone iodine
Povidone iodine is the most widely used general antiseptic for wound healing and is readily available in any pharmacy. This medicine is good for open wounds and prevents them from becoming infected. As a result, the wound will dry quickly.
8. Petroleum jelly
Petroleum jelly or vaseline are also good for providing sufficient moisture for wound healing. Petroleum jelly can be used for a variety of wounds, except for infected wounds. However, make sure to clean the wound first before applying it.
