Study Notes
Inflammation and Healing
- Inflammation is a nonspecific response to tissue injury
- Tears are a first line of defense
- Specific defenses include phagocytosis and sensitized T lymphocytes
- Chemical mediators are released during inflammation, including histamine and prostaglandins
- Unnecessary inflammation can be mediated by resolvins, which limit ongoing response
- Granulation tissue is highly vascular, fragile, and susceptible to infection
- Inflammatory response involves increased permeability of blood vessels, dilation of blood vessels, and the migration of leukocytes
- Phagocytosis is the process of engulfing foreign material by leukocytes
- Systemic effects of severe inflammation include fatigue, anorexia, and mild fever
- Replacement of damaged tissue by similar cells is called regeneration
- Scar tissue, primarily collagen fibers, forms during repair
- Glucocorticoids reduce capillary permeability to decrease inflammation
Fever
- Fever is triggered by pyrogens released into the circulation
- Fever mechanisms involve general cutaneous vasodilation to help lower body temperature
- Fever is caused by a signal to the thalamus
- Fever is not caused by viral infection
- Fever and pain relief is provided by acetaminophen, but it is not an anti-inflammatory agent
Burns
- Burns are classified based on depth of tissue destruction (first-degree, superficial, deep partial-thickness, and full-thickness)
- Full-thickness burns destroy epidermis and dermis
- Burn percentage can be estimated for surface area evaluation
- Burns can be infected by microbes that survive in hair follicles
- Large burn areas lead to decreased blood pressure due to fluid shifts
Inflammatory Response
- Hyperemia is increased blood flow in the affected area due to vasodilation
- Inflammatory response involves capillary permeability
- Biosynthetic skin substitutes are used to treat large full-thickness burns to minimize infection and fluid loss, and promote faster healing
- Purulent exudates contain leukocytes, bacteria, and cell debris
- Isoenzymes indicate the location of the inflammatory response; they are a type of plasma protein that's normally present
- Serous exudate is a thin, watery fluid
