purulence
Pronunciation: PYUR-you-lence
Thick, yellow-green infected discharge containing white blood cells, bacteria, and cellular debris.
Full Definition
Purulence refers to the formation and discharge of pus, a thick, opaque fluid composed of dead white blood cells, bacteria, tissue debris, and protein-rich fluid. In acute care surgery, purulence indicates active bacterial infection and is commonly encountered in surgical site infections, abscesses, and infected wounds. The presence of purulent drainage typically requires wound cultures, antibiotic therapy, and often surgical intervention for source control. The appearance, odor, and volume of purulent material should be documented, as these characteristics can provide clues about the causative organism and guide treatment decisions.
Usage
Usage note: Adjective form is 'purulent.' Document characteristics including color, odor, and volume.
