What is Serosanguineous drainage?
Serosanguineous drainage is the most common type of wound drainage secreted by an open wound in response to tissue damage. It is a thin and watery fluid that is pink in color due to the presence of small amounts of red blood cells.
What is active and passive drainage?
Drains are classified by various systems: open or closed and passive or active. Passive drains rely on gravity, body movement, pressure differentials, or overflow to move fluid or gas; active drains use intermittent or continuous negative pressure to pull fluid or gas from a wound or body cavity.
What is the difference between Slough and pus?
Slough is made up of white blood cells, bacteria and debris, as well as dead tissue, and is easily confused with pus, which is often present in an infected wound (Figs 3 and 4).
What is the purulent?
Definition of purulent 1 : containing, consisting of, or being pus a purulent discharge. 2 : accompanied by suppuration.
What is passive drainage?
Passive Wound Drainage is a closed system designed for passive post-operative wound drainage. The passive wound drainage system is connected to a spiral drain which is placed directly into the surgical wound.
What is active drain?
Active drains apply an artificial pressure gradient to pull fluid or gas from a wound or body cavity. Negative pressure increases the efficiency of active over passive drains, enables placement of the drain exit in any position, can remove fluid against gravity if necessary, and can be used to collapse dead space.
What dressings lift Slough?
There are dressings specifically designed to promote autolytic debridement, which include thin films, honey, alginates, hydrocolloids, and PMDs. Hydrogels and hydrocolloids are additional dressing choices that may be effective in removing slough.
What is suppurative and purulent?
Both purulent and suppurative are used to describe pus formation. However, others employ purulent and suppurative in a more specific way: purulent is used to describe the pus forming in the affected area whereas suppurative is used to describe the pus oozing from the site of injury or infection.
