What is pathophysiology of cellulitis?

PATHOPHYSIOLOGY. As the offending organism invades the compromised area, it overwhelms the defensive cells (neutrophils, eosinophils, basophils, and mast cells) that normally contain and localize inflammation and cellular debris accumulates. As cellulitis progresses, the organism invades tissue around the initial wound …

What is the pathophysiology process that is going on with a patient that has cellulitis from a wound?

Pathophysiology. Cellulitis is characterized by erythema, warmth, edema, and tenderness to palpation resulting from cytokine and neutrophil response from bacteria breaching the epidermis.

What is the cause of cellulitis?

Cellulitis is usually caused by a bacterial infection. The bacteria can infect the deeper layers of your skin if it’s broken, for example, because of an insect bite or cut, or if it’s cracked and dry.

How to describe cellulitis?

Cellulitis (sel-u-LIE-tis) is a common, potentially serious bacterial skin infection. The affected skin appears swollen and red and is typically painful and warm to the touch. Cellulitis usually affects the skin on the lower legs, but it can occur in the face, arms and other areas.

What is the pathophysiology of skin infection?

Pathophysiology of bacterial skin infections Most common conditions that can predispose an individual to bacterial skin infections involve cases when the integrity of the skin barrier is breached; therefore trauma such as abrasion, excoriation, laceration or ulceration may result in a vulnerable skin.

Is cellulitis arterial or venous?

Most commonly, it occurs in areas that may have been damaged or are inflamed for other reasons, such as inflamed injuries, contaminated cuts, or areas with poor skin hygiene. Bad circulation from poor vein function or peripheral arterial disease is a common cause of cellulitis.

What bacteria causes cellulitis?

The most common bacteria that cause cellulitis include:

  • Group A ß – hemolytic streptococcus (Strep)
  • Streptococcus pneumoniae (Strep)
  • Staphylococcus aureus (Staph)

What is uncomplicated cellulitis?

Uncomplicated SSTIs include superficial cellulitis, folliculitis, furunculosis, simple abscesses, and minor wound infections. These infections respond well to either source control management (ie, drainage or debridement) or a simple course of antibiotics. These infections pose little risk to life and limb.

What is the cause of cellulitis in the legs?

Cellulitis is usually caused when bacteria enter a wound or area where there is no skin. The most common bacteria that cause cellulitis include: Group A ß – hemolytic streptococcus (Strep) Streptococcus pneumoniae (Strep)

Which is the major organism causing skin and soft tissue infections?

The following are the most important pathogens: Staphylococcus aureus (the most common pathogen) Streptococcus pyogenes. Site-specific infections – Indigenous organisms (eg, gram-negative bacilli in perianal abscesses)
