Clear or pale-yellow watery fluid can occur during healing, while pink fluid may contain a small amount of blood. Thick, cloudy, green, brown, or foul-smelling drainage—and any sudden increase—needs clinical review. Color alone cannot diagnose infection, so consider the amount, thickness, odor, pain, redness, and how the person feels.
A small amount of thin, clear to pale-yellow fluid may be expected in some wounds. Pink or light-red watery drainage usually reflects fluid mixed with a small amount of blood. A clinician should still review drainage that is increasing, soaking dressings, or continuing longer than expected.
Thick or cloudy drainage may contain inflammatory cells and debris. Green or brown color can have several causes, including bacteria, old blood, dead tissue, or dressing material. A wound examination—and sometimes a properly collected culture—is needed to understand the cause.
Note the color, thickness, odor, approximate amount, and number of dressings saturated. Also record new pain, warmth, swelling, redness, fever, or changes in the wound’s size. Do not pour antiseptics into the wound or start leftover antibiotics without instructions.
Seek urgent or emergency care rather than judging drainage by color when serious symptoms occur.
