“Inflammation is an adaptive response to injury that brings fluid, dissolved substances and blood cells into the interstitial tissues where the invasion or damage has occurred.”

Inflammation can occur anywhere in the body, here are a few types of inflammations that may occur in the body:Acute Inflammation:

Symptoms of Inflammation Redness Swelling Pain Heat Loss of function

Pathophysiology of Inflammation

The basic components of the inflammatory process includes: VasodilationIncreased vascular permeability Emigration of white blood cells

When tissue is damaged for example a poke in the skin with a nail, bacteria is released in the interstitial fluid. The tissue cells immediately release chemical messengers (chemokinds), and the mast cells release histamines. Histamines cause the capillary endothelial cells to become larger and more further apart (called vasodilation) this also causes blood flow to increase (increased vascular permeability). Phagocytes (white blood cells) are released from the capillaries (emigration of white blood cells). The phagocytes begin to engulf the bacteria and dead cells. Platelets move out of the capillary to seal the wounded area.

Nursing Interventions For Inflammation

Because inflammation can occur anywhere in the body, it is important to note that nursing interventions wont be the same for some types of inflammation. Most cases of inflammation require appropriate assessments and the application of ice, and the administration of pain medication or anti-inflammatory drugs.
