Medical Terminology for Mixtures of Blood and Pus

Terminology for Different Types of Discharge

The medical term for a mixture of blood and pus is "hemorrhagic pus" or "sanguinopurulent discharge," as defined by Clinical Infectious Diseases 1, 2
Serosanguinous discharge, a mixture of serum and blood, appears pink or blood-tinged, according to Clinical Infectious Diseases 1
Purulosanguinous discharge, also called sanguinopurulent, is a mixture of pus and blood, appearing as bloody pus, as described by Clinical Infectious Diseases 1, 2
Purulent discharge consists of pure pus, typically appearing thick, opaque, and yellow-white, as noted by Clinical Infectious Diseases 2, 3

The presence of pus indicates an active infection with accumulation of white blood cells fighting the infection, as stated by Clinical Infectious Diseases 2
Purulent discharge is commonly seen in cutaneous abscesses, infected epidermoid cysts, furuncles, and carbuncles, according to Clinical Infectious Diseases 2, 3, 4, 5
Blood mixed with pus may indicate active infection with tissue damage causing bleeding, more severe or invasive infections, or possible trauma to the infected area, as suggested by Clinical Infectious Diseases 2

Visual assessment of discharge type has only moderate predictive value for specific pathogens, as found by Diabetes/Metabolism Research and Reviews 7
Gram stain and culture of purulent or sanguinopurulent material are recommended for proper identification of causative organisms, according to Clinical Infectious Diseases 4, 5

The presence of pus generally indicates the need for drainage in addition to antimicrobial therapy, as recommended by Clinical Infectious Diseases 1, 2
For abscesses, furuncles, and carbuncles, incision and drainage is the primary treatment, with antibiotics being adjunctive therapy based on systemic symptoms, as stated by Clinical Infectious Diseases 4, 5
For empyema or other enclosed collections of pus, drainage via appropriate methods is typically required, as noted by Thorax 6
