(Redirected from Laudable pus)

Definition[edit | edit source]

Pus is the collection of dead tissue such as white blood cells, secretions or exudate, that collects after certain types of bacterial, protozoal and fungal infections and is typically white-yellow, yellow, or yellow-brown

Abscess[edit | edit source]

An abscess is nothing but collection of pus in an enclosed space. If there is a visible collection of pus, then it is called pustule or pimple.

Composition[edit | edit source]

Pus consists of a thin, protein-rich fluid, filled with dead tissues, and is also known as liquor puris

Pyogenic[edit | edit source]

Bacteria that cause pus are called pyogenic.

In almost all cases when there is a collection of pus in the body, a clinician will try to create an opening to drain it. This principle has been distilled into the famous Latin aphorism "Ubi pus, ibi evacua" ("Where there is pus, evacuate it").

Examples of pyogenic infections[edit | edit source]

Some disease processes caused by pyogenic infections are impetigo, osteomyelitis, septic arthritis, and necrotizing fasciitis.

Symptoms[edit | edit source]

If the pus is superficial, it is usually seen as a swelling that is visible or palpable. If the pus is deep in the body, it may lead to symptoms such as obstruction, based on the location. In most cases, the symptoms such as fever, chills, loss of appetite, pain, redness of the skin etc. will also be seen.

Diagnosis[edit | edit source]

Diagnosis is through a thorough history, and physical examination, blood tests including culture, and sensitivity, imaging studies such as ultrasound, CT scan or MRI might also be used.

Treatment[edit | edit source]

The pus must drain for the infection to heal. You may use warm compresses to “ripen” the abscess, but DO NOT try to pop or puncture the abscess yourself. If your abscess is not draining on its own, your doctor may help the pus to drain through a small incision. Sometimes cotton gauze is also packed inside the abscess cavity to draw out the pus. Important advice for patients: • Avoid touching the abscess with bare hands. • Keep the abscess covered with a clean, dry dressing. If the dressing becomes wet with pus, it should be carefully changed and thrown away in a plastic bag. Pus is very contagious. • Wash your hands frequently with soap and water or hand sanitizer. • Avoid contact-sports and gym class until the wound is completely healed. • Avoid close skin-to-skin contact with other people to keep the infection from spreading.

Pyogenic bacteria[edit | edit source]

A great many species of bacteria may be involved in the production of pus.

Staphylococcus aureus bacteria is the most common cause of boils.
