Exudate

As exudate is known in medicine (typically caused by inflammation ) discharges, as opposed to non-inflammatory transudates. The separation of the liquid is called exudation. Exudates contain more than 30 g / l of protein (including enzymes ), glucose and other blood constituents. Exudates with a high proportion of cells and cell debris are purulent.

The exudate accumulates inside the body in a non- preformed (not previously present ) cave, this is called seroma (not pus ) or abscess ( pus ) denotes when the body manages an encapsulation. A boundless purulent spread is called cellulitis. Flows, however, the exudate into existing body cavities, is spoken by a effusion, a purulent exudate is then called empyema.

Formation

Exudate is caused by inflammation, for example, infection or tissue injury. The walls of the capillaries are permeable to macromolecules and cells to allow to enter immune cells and humoral components of the immune system to the site of inflammation. The body tries to secrete pathogens and dead tissue.

Components

Exudate contains admixtures of proteins, blood, cells or cell debris and in the case of inflammation, microorganisms, leukocytes and endogenous feeding and immune cells ( macrophages).

To determine the components, you can make a smear for skin wounds. This can provide information as to whether antibiotic treatment is useful.

Scab

In superficial wounds (eg, abrasions ) leads clotted exudate and its drying up to form a crust, popularly known as scab, scab, or Bratze (wound ) scab. Heavy healing superficial wounds that constantly secrete much exudate are also referred to as exuding wounds, because in them there is no crust may form.
