What is wound exudate?

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 are the three 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.

Is exudate interstitial fluid?

Wound exudate is derived from interstitial fluid found in the spaces between cells in body tissues (the interstitium). Interstitial fluid is formed from the blood in capillaries and has similar components to blood plasma (Kiang et al, 2017).

What is exudate production?

Exudate is produced from fluid that has leaked out of blood vessels and closely resembles blood plasma. Fluid leaks from capillaries into tissue at a rate that is determined by the permeability of the capillaries and the hydrostatic and osmotic pressures across the capillary walls.

Where does the exudate of a wound come from?

WORLD UNION OF WOUND HEALING SOCIETIES CONSENSUS DOCUMENT FORMATION OF WOUND EXUDATE Wound exudate is derived from interstitial fluid found in the spaces between cells in body tissues (the interstitium). Interstitial fluid is formed from the blood in capillaries and has similar components to blood plasma (Kiang et al, 2017).

What makes an ascitic fluid an exudate or transudate?

A low SAAG (<1.1g/dL) suggests the ascitic fluid is an exudate. Another way of differentiating between an exudate and a transudate is to assess the ascitic fluid’s lactate dehydrogenase (LDH) level: This method has largely been replaced by the use of SAAG.

What does exudate stand for in medical terms?

Slough and Necrotic Tissue Written by Sharon Takiguchi 18 December, 2018 Exudate refers to the draining of liquid from open wounds in the human body, reports Medscape.com.

When does exudate become a sign of infection?

If the fluid becomes very thick, this can be a sign of infection. Exudate is a byproduct of vasodilation during the inflammatory stage and in chronic wounds the drainage changes and contains proteolytic enzymes.
