Slough will always show signs of stringy textures, yellow coloring, and will be more granular after cleansing. Purulence will always emit an odor after cleansing and will show signs of infection and erythema.
What is the difference between purulent drainage and exudate?
Purulent wound drainage, also called “pus” is a milky, malodorous fluid yellow, green, grey, or tan in color. Purulent exudate is composed of debris, white blood cells, and dead bacteria, and is almost always a sign of wound infection.
What is slough tissue?
Slough is defined as yellow devitalized tissue, that can be stringy or thick and adherent on the tissue bed. This wound bed has both yellow stringy slough as well as thick adherent slough. Slough on a wound bed should be surgically debrided to allow for ingrowth of healthy granulation tissue.
What is the difference between Slough and exudate?
Slough refers to the yellow/white material in the wound bed; it is usually wet, but can be dry. It generally has a soft texture. It can be thick and adhered to the wound bed, present as a thin coating, or patchy over the surface of the wound (Figure 3). It consists of dead cells that accumulate in the wound exudate.
What is the difference between Slough and granulation tissue?
Slough is usually a combination of leucocytes, bacteria, devitalised tissue or debris and usually has a moist, shiny stringy appearance or may be firmly attached to the wound bed. Granulation tissue is a collagen rich tissue forming at the site of an injury during the proliferative phase.
What is a purulent exudate mean?
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.
What is the difference between Slough and pus?
Slough will always show signs of stringy textures, yellow coloring, and will be more granular after cleansing. Purulence will always emit an odor after cleansing and will show signs of infection and erythema. When in doubt, consult with the Cork Medical wound care team for further evaluation.

What color is slough tissue?
The appearance of slough is typically a pale yellow, viscous fibrinous tissue and can range from yellow to tan, usually, but not always, covering the entire wound bed.
What is in purulent discharge?
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. There may be an unpleasant smell to the fluid, as well.
What is Slough in medical term?
: dead tissue separating from living tissue. especially : a mass of dead tissue separating from an ulcer. slough.
What are the three types of exudates?
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.
Does Slough mean infection?
If what you’re cleansing out of the wound is stringy and yellow, and the wound base appears more granular after cleansing, it is most likely slough. If there is an odor, erythema, and signs and symptoms of infection, you’re most likely dealing with purulence or purulent drainage.
What does a slough look like?
Sloughs along the edges of rivers form where the old channel of the river once flowed. These areas are also referred to as oxbows because they tend to form at a bend in the old river bed, making them look like the U-shaped collar placed around the neck of an ox to which a plow is attached.
What is the difference between slough and necrotic tissue?
Necrotic tissue, slough, and eschar
The wound bed may be covered with necrotic tissue (non-viable tissue due to reduced blood supply), slough (dead tissue, usually cream or yellow in colour), or eschar (dry, black, hard necrotic tissue). Such tissue impedes healing.
What is the difference between Slough and eschar?
There are two main types of necrotic tissue present in wounds: eschar and slough. Eschar presents as dry, thick, leathery tissue that is often tan, brown or black. Slough is characterized as being yellow, tan, green or brown in color and may be moist, loose and stringy in appearance.
What are the 4 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 an example of purulent exudate?
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.
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 does a purulent mean?
adjective. full of, containing, forming, or discharging pus; suppurating: a purulent sore. attended with suppuration: purulent appendicitis. of the nature of or like pus: purulent matter.
What is Slough made of?
Slough is a complex, generally fibrinous, mass that consists variously of fibrin, deoxyribonucleo-protein, leucocytes, bacteria, proteinaceous material, and serous exudate (Thomas, 1997; Black et al, 2010).
What is the difference between Slough and biofilm?
Wound slough has been described as a viscous, yellow, and relatively opaque layer on wound beds, while biofilm found in wounds has been suggested to appear more gel-like and shiny23.
