Purulent or suppurative exudate consists of plasma with both active and dead neutrophils, fibrinogen, and necrotic parenchymal cells. This kind of exudate is consistent with more severe infections, and is commonly referred to as pus.
What is the difference between purulent and exudate?
A: Exudate or drainage that comes out of a wound is thin and watery in appearance. When accompanied by blood, it appears slightly pink or red. If the exudate is thick, milky white with a yellow, green, or brown appearance, then the wound is purulent.
How do you get purulent exudate?
Purulent drainage is a sign of infection. It’s a white, yellow, or brown fluid and might be slightly thick in texture. It’s made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound.
What are the 4 types of exudate?
Types of Exudate
- Serous – a clear, thin and watery plasma.
- Sanguinous – a fresh bleeding, seen in deep partial- and full-thickness wounds.
- Serosanguineous – thin, watery and pale red to pink in color.
- Seropurulent – thin, watery, cloudy and yellow to tan in color.
What is an example of an exudate?
Pus is an example of exudate found in infected wounds that also includes bacteria and high concentrations of white blood cells. Clear blister fluid is an example of an exudate that contains water (and solutes) together with some plasma proteins, but not many blood cells.
Does exudate mean healing?
Wound exudate is a natural phenomenon that contributes to healing. Understanding what causes changes in the amount, colour, consistency and odour of exudate enables more effective wound care.
What do you do if you have purulent drainage?
See your doctor immediately if you notice a change in color or odor of the fluid oozing from your wound. Purulent drainage is yellow, green, brown, or white and has a strong odor. The earlier an infection is caught, the easier it can be treated.
Should exudate be removed?
Why is it important to manage exudate? Effective exudate management can reduce time to healing, reduce exudate- related problems such as periwound skin damage and infection, improve patients’ quality of life, reduce dressing change frequency and clinician input, and so, overall, improve healthcare efficiency.
What does purulent exudate look like?
Purulent drainage is liquid or discharge that oozes from a wound. People usually observe this fluid has a milky look and texture. Purulent drainage is easily spotted, as it is thick and can vary in color, from grayish or yellow to green and even brown.

Does exudate indicate infection?
Exudate that becomes a thick, milky liquid or a thick liquid that turns yellow, tan, gray, green, or brown is almost always a sign that infection is present. This drainage contains white blood cells, dead bacteria, wound debris, and inflammatory cells.
What color is exudate fluid?
Seropurulent exudate is thin, watery, cloudy, and yellow to tan in color. Purulent exudate is thick and opaque. It can be tan, yellow, green, or brown in color. It’s never normal in a wound bed.

Exudate is usually amber or straw coloured, similar to plasma (Davies, 2012). Any change in colour can indicate a possible problem. Green usually indicates bacterial infection practice.
How do you remove exudate from a wound?
Dressings are the main option for managing high exudate levels and are designed to handle fluid through various different mechanisms. Negative pressure wound therapy (NPWT) may also be useful when soiling and leakage pose a significant problem (Romanelli et al, 2010).
What does wound exudate look like?
Serosanguinous drainage is the most common type of exudate that is seen in wounds. It is thin, pink, and watery in presentation.

Does exudate move to the site of infection?
Exudate consists of fluid and leukocytes that move to the site of injury from the circulatory system in response to local inflammation.
How are purulent infections treated?
Vancomycin, linezolid, tigecycline, daptomycin, ceftaroline, and telavancin are all considered appropriate antimicrobial agents for treatment of severe purulent infections, while trimethoprim-sulfamethoxazole and doxycycline are recommended for moderate purulent infections.
