Which type of drainage is characterized by a yellow, watery appearance?

The type of drainage characterized by a yellow, watery appearance is serous drainage. This type of fluid typically results from the initial stages of healing or from inflammation. Serous drainage is generally clear, thin, and straw-colored, reflecting an accumulation of serum, the clear portion of blood. It usually indicates a non-infected site, making it a common finding in wounds that are healing appropriately.

Other types of drainage differ in their characteristics; sanguineous drainage consists of fresh blood and appears red, purulent drainage is thick, yellowish-green, or cloudy, indicating infection, while fibrinous drainage can be sticky and consist of clotted proteins, often indicating more serious inflammation. Understanding these properties helps healthcare professionals assess wound healing appropriately.
