Serosanguinous drainage is the most common type of exudate that is seen in wounds. It is thin, pink, and watery in presentation. Purulent drainage is milky, typically thicker in consistency, and can be gray, green, or yellow in appearance. If the fluid becomes very thick, this can be a sign of infection.
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.
What is the difference between drainage and exudate?
Wound drainage is a fluid produced from the blood vessels during the inflammatory phase of healing, which is similar to blood plasma. Exudate consists of a mixture of water, proteins, white blood cells, inflammatory mediators, and electrolytes, which play essential roles in wound healing.
Is purulent an exudate?
Purulent – a thick and opaque exudate that is tan, yellow, green or brown in color. It’s never normal in a wound bed, and is often associated with infection or high bacteria levels.
What is purulent drainage?
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 3 types of wound drainage?
Drainage can be (1) serous (clear and thin; may be present in a healthy, healing wound), (2) serosanguineous (containing blood; may also be present in a healthy, healing wound), (3) sanguineous (primarily blood), or (4) purulent (thick, white, and pus-like; may be indicative of infection and should be cultured).
What is exudate drainage?
Open wounds produce a fluid that is known as exudate. Exudate has been described as ‘wound fluid’, ‘wound drainage’ or ‘an excess of normal fluid’ (WUWHS, 2007) (Figure 1). However, wound exudate is a complex phenomenon that requires careful nursing management if it is to assist healing.
What are the 4 types of exudate?
Types of Wound Exudate
There are four types of wound drainage: serous, sanguineous, serosanguinous, and purulent.
Is purulent exudate the same as pus?
Purulent wound drainage is commonly called “pus” and often has a foul or unpleasant smell. Additionally, it can increase an inflammatory response, resulting in intense pain at the wound site and surrounding skin. Wound drainage with a foul odor in and of itself does not indicate infection.
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.
What type of exudate is pus?
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 color is exudate?
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 does exudate become purulent?
A purulent exudate is an inflammatory exudate with a high concentration of leukocytes – predominantly neutrophils – dead cell matter and inflammatory molecules e.g. cytokines, lysozymes. The degree of enzyme proteolysis determines the thickness of the fluid.
How do you identify purulent drainage?
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. Purulent drainage usually indicates a sign of an infection.
What is an exuding wound?
Exudate consists of fluid and leukocytes that move to the site of injury from the circulatory system in response to local inflammation. This inflammatory response leads to blood vessel dilatation and increased permeability, resulting in increased production of exudate.
What wound class is purulent drainage?
Class IV: Dirty/infected
Old traumatic wounds with retained devitalized tissue; procedures with existing clinical infection (purulence already present in wound) or perforated viscera.
What does purulent drainage smell like?
Purulent wound drainage is thick with a yellow, green or brown color, with a pungent, strong, foul, fecal or musty odor. Purulent drainage is a sign of an unhealthy wound and demands treatment.
What color is serous drainage?
Serous drainage
It is often thin and watery and will usually have a clear to yellowish or brownish appearance. Small amounts of serous drainage are normal during the first stages of healing.
What are the 4 classifications of wounds?
Definition/Introduction
- Class 1 wounds are considered to be clean. They are uninfected, no inflammation is present, and are primarily closed.
- Class 2 wounds are considered to be clean-contaminated.
- Class 3 wounds are considered to be contaminated.
- Class 4 wounds are considered to be dirty-infected.
What are the three 3 most common types of wound infections?
The most common causative organisms associated with wound infections include Staphylococcus aureus/MRSA, Streptococcus pyogenes, Enterococci and Pseudomonas aeruginosa.
