Overview
Discharge is an exudate draining from the wounds. It can be internal or external. It is formed from the serum.
Classification
Serous
(resembling serum)
- Clear or straw colored in appearance.
- Arises from protein and fluid in the tissue.
- Supports the healing process and contains protein, electrolytes, sugar and white cells.
- Occurs as a normal process of healing.
Sanguinous
(contains blood cells)
- Red drainage from trauma to a blood vessel.
- This may occur with the cleaning of a wound or disturbance to a wound.
- The consistency appears thin and watery with sanguinous fluid.
- Discharge fluid contains red blood cells, which give it its red appearance.
Serosanguinous
(consisting of serum and blood)
- Serosanguinous fluid appears pink due to a small number of blood cells mixing with serous drainage.
- Thin and water-like consistency.
- Serosanguinous fluid is a normal occurrence in the healing of wounds.
Purulent
(containing pus)
- Purulent discharge is yellow, gray or green in color.
- It results when infection occurs.
- The discharge fluid has infectious microbes, white cells and other inflammatory cells.
- The volume of the exudate increases with prolonged infection.
Mucopurulent
- Mucopurulent discharge is pus with mucoid cells.
- It is a whitish-yellow or yellow substance produced during inflammatory responses of the body.
- It can be noticed in regions of pyogenic bacterial infections.
- It consists of a thin, protein-rich fluid, known as liquor puris, and dead neutrophils (white blood cells), which are part of the body's innate immune response.
Hemorrhagic
(characterized by hemorrhage)
- Hemorrhagic discharge indicates a leaking blood vessel leaking blood.
- The consistency is thicker than sanguinous fluid.
- It may require surgical methods to control bleeding.
