What type of drainage is characterized as clear, watery plasma?

The type of drainage characterized as clear, watery plasma is known as serous drainage. This type of drainage is typically seen in wounds or injuries where there is minimal inflammation or infection. Serous fluid is composed primarily of serum, which is the clear, pale yellow liquid that separates from the blood when a clot forms. It often occurs in conditions such as allergies, acute inflammation, or during the inflammatory phase of healing, indicating a normal healing process.

In contrast, purulent drainage is thick and often cloudy, containing pus, which signifies an infection. Sanguineous drainage refers to blood drainage, which can indicate active bleeding or a hemorrhagic condition. Serosanguineous drainage is a combination of serous and sanguineous fluids, often seen in wounds that are healing but may still have a small amount of blood mixed with the clear plasma. Understanding these types of drainage helps nurses assess the status of a wound and the healing process effectively.
