Rubor

Rubor is one of the five cardinal signs of inflammation. It is characterized by redness or reddening of the skin or mucous membranes, typically caused by dilation and congestion of the capillaries. Rubor is often accompanied by other signs of inflammation, including calor (heat), dolor (pain), tumor (swelling), and functio laesa (loss of function).

Causes

Rubor is caused by the dilation of small blood vessels in the area of injury. This is a response to injury or infection, as the body attempts to deliver more blood to the affected area to aid in healing. The increased blood flow results in a visible redness of the skin or mucous membranes.

Diagnosis

Rubor is typically diagnosed through a physical examination. The affected area will appear red and may feel warm to the touch. In some cases, additional tests may be needed to determine the underlying cause of the inflammation.

Treatment

Treatment for rubor typically involves addressing the underlying cause of the inflammation. This may include the use of anti-inflammatory medications, rest, and in some cases, surgery. In cases where rubor is caused by an infection, antibiotics may be prescribed.
