Understanding wound exudate is crucial for effective wound care and infection management. Different types of fluid that emerge from a wound can provide valuable insights into the healing process and potential complications. Learn to identify the various types of wound exudate and understand what their appearances reveal about the state of the wound. This knowledge helps monitor wound health, detect signs of infection early, and make informed decisions about appropriate care and treatment.

Serous:

Serous fluid is a clear, straw-coloured, slightly thin fluid that usually appears in the initial stages of wound healing. It typically emerges in small amounts and commonly occurs in superficial abrasions. This fluid helps to lubricate the wound and supports the healing process. Typically, simple primary dressings like island dressings are sufficient to manage and absorb serous fluid while protecting the wound.

Sanguineous/Blood:

Sanguineous (blood) fluid is typically observed within the first 24 hours of injury, especially in deep wounds. It is a normal part of the healing process as it helps to form clots and start repair. However, if the wound is older than 48 hours and continues to produce sanguineous fluid, it may indicate new trauma or complications that require medical attention.

Serosanguineous:

Serosanguineous fluid is a mix of blood and serous fluid, appearing yellow with red tinges. It commonly oozes from wounds as part of the healing process. You typically observe this fluid type in the early stages of wound recovery, and it indicates a normal response to the injury. Previously, it was referred to as haemoserous.

Purulent:

Purulent fluid is thick and opaque, often changing colour from yellow to green or brown. These colour changes usually indicate the presence of infection, which requires medical intervention to adequately address the infection and ensure effective treatment.
