Have you noticed the yellow, purulent fluid seeping from the wound after each injury? It is called exudate and is mainly composed of plasma and extracellular fluid.
While it may appear unpleasant at first, exudate plays a pivotal role in wound healing. In the early stages of wound healing, exudate plays a cleaning role. As the wound heals, the amount of exudate gradually decreases, and its composition changes, promoting tissue repair and providing the essential nutrients.[1]
When there is excessive exudate, simply wiping it with tissue or cloth has little effect and may also result in secondary damage to the wound. Thus, careful exudate management with advanced wound care dressings to form moisture balance at the wound interface is crucial for wound healing.
If you’re wondering how a dressing can help heal wounds, let’s briefly discuss its role in exudate management below.
What Causes Wound Exudate?
The detailed components of wound exudate include water, electrolytes, proteins, immune cells, and growth factors.[1] These components are important in wound healing, such as cleaning wounds, regulating immune responses, and promoting tissue repair.
Under normal conditions, the tight connection between blood vessels and endothelial cells maintains the stability of fluid and cellular components. However, special causes can lead to blood components and extracellular fluid leaking from blood vessels into surrounding tissues, forming large amounts of exudate.
Here are some of the special causes of exudate:
- Inflammation is the most common cause, promoting histamine release from the immune system and leading to vasodilation and increased cell permeability. Body fluids will seep out of blood vessels into surrounding tissues.
- When a wound is infected with bacteria, fungi, or viruses, it can cause serious inflammatory reactions and form exudate.
- Tissue damage caused by trauma, surgery, and other causes can damage blood vessels and cells and lead to body fluid leakage.
- Long-term chronic diseases, such as venous ulcers and diabetes, can cause circulatory disorders and tissue edema, increasing exudates.
- Any foreign bodies, such as fragments and dust, can stimulate inflammatory reactions and the production of exudates.
Types of Wound Exudate
The amount and composition of exudate vary at different stages of the wound. In addition, different wounds can also lead to different types of exudates. According to the color and consistency of the exudate, it can be divided into the following four types[2]:
-
Serous Exudate:
The normal part of healing is the serous exudate. It appears clear or pale yellow and contains plasma and a small amount of protein. Some blood cells are also present in this type of exudate. Overall, serous indicates a normal state of wound healing.
-
Sanguineous Exudate:
If you have a deep and large wound, sanguineous exudate will be formed at that place. It is red or dark red, containing many red blood cells and plasma, usually caused by vascular damage. Small amounts of this wound drainage are considered normal.
-
Purulent Exudate:
If you see fluid that appears yellow-green, grey-white, or brown in color, it is the purulent exudate. The presence of this exudate indicates a severe bacterial infection. It is also commonly known as pus and contains a large number of white blood cells and bacteria.
-
Serosanguinous Exudate:
Another thin type of exudate most commonly seen at wound sites is the serosanguinous exudate. It is pale red to pink in color and contains small amounts of blood.
How to Select Advanced Wound Care Dressings for Exudate Wounds?
Some wounds often result in high exudate production and thus need proper care and treatment for optimum healing.
Fortunately, there are different advanced wound care dressings to treat exudate wounds. The following is a guide about how to select the most suitable dressings for you.
1. Absorptive Capacity
The first principle of dressing selection for exudate management is absorptive capacity. The selection of an appropriate dressing is contingent upon the quantity of exudate present. In the event that the exudate level is minimal, a foam dressing or a silicone foam dressing may be considered. Silicone foam dressing’s silicone layer prevents skin trauma during dressing changes. In the event of a considerable quantity of exudate, it is recommended that a super absorbent dressing or silicone super absorbent dressing be employed.
2. Breathability
Breathability is another important consideration when choosing advanced wound care dressings. Good breathability allows the wound to be exposed to oxygen, promoting the formation of healthy granulation tissue.
Breathable wound dressings can reduce skin maceration and itching, increasing patient comfort. It also prevents bacterial growth and reduces the infection risks.
3. Antibacterial Performance
The antimicrobial performance of advanced wound care dressings helps provide a favorable healing environment for exudate wounds by reducing infection.
