Inflammation And Burns Flashcards
What are the 5 cardinal signs of inflammation
Heat Redness Pain Swelling Loss of function
What are the inflammatory mediators
Histamines
Plasma proteases
Prostoglandins
Leukotrienes
What are the vascular responses to acute inflammation
Constriction of small vessels Vasodilation of arteries Congestion causes warmth and redness Increased capillary permeability Fluid movement into tissues Clotting
What is the process of the immune response to inflammation
Pavementing - cells line walls
Emigration/Diapedesis - leukocytes start to move to site of injury
Chemotaxis - leukocytes attach to injury site
Phagocytosis - debris removal
Serous exudate
Watery
Some proteins
Some white blood cells
Fibrinous exudate
Thick
Sticky
High cell and fibrin content
Purulent exudate
Thick and yellow-green
More leukocytes, debris and microorganisms
The proliferation of what occurs in chronic vs acute inflammation
Fiberblasts rather than exudates
What are the anti inflammatory effects of glucocorticoids?
Decreased cap permeability
Enhanced effectiveness of epi and norepinephrine
Reduced leukocyte presence
Reduced immune response
What are the adverse effects of glucocorticoids
Atrophy of lymphoid tissue Reduced hemopoiesis Decreased protein synthesis Increased tissue breakdown Delayed healing Delayed growth in children Sodium and water retention
RICE therapy
Rest
Ice
Compression
Elevation
What changes occur in the blood with inflammation?
Increased leukocytes Differential count Increased plasma protein Presence of c-reactive protein Increased ESR Cell enzyme presence
How is burn severity measured?
Thickness and surface area covered
Rule of Nines
What are the steps in treatment for burns?
Treat immediate problems like shock, respiratory problems, anemia, dehydration etc
Cover burn to prevent infection
Control scarring and avoid keloids
Therapy
1st degree burn
Superficial partial thickness
No blisters
Involve epidermis
