Burns, Normal Lab Values Flashcards
Hematocrit- the percentage of red blood cells in blood and thus the viscosity of the blood
Normal values for men and women:
Men: 42-45%
Women: 37-47%
Hemoglobin levels have a bearing on the amount of oxygen transported around the body.
Normal values for men and women:
Men: 14-17.4 g/dL
Women: 12-16 g/dL
Prothrombin measures the time it takes for the blood to clot.
Normal time:
11-13 sec
International normalized ratio (INR) uses prothrombin results. Normal range: Therapeutic range (PE, A-Fib):
Normal: 0.8-1.2
Therapeutic: 2.0-3.0
*therapeutic range for artificial heart valves: 2.5-3.5
Platelets
Normal range:
140-400 k/uL
140,000-400,00
Glucose
Normal range:
70-100 mg/dL
90-130 mg/dL (fasting)
Immediate response after burns is ____. (Fluid and protein loss)
Systemically there will be increased blood viscosity, why?
Shock
Bc you’re losing fluid, you will have a higher percentage of the blood that is blood/cellular components rather than fluid
2 major classifications of burns:
Depth
Extent
The degree to which a burn crosses tissue damage is dependent on the following six factors:
- Duration of destructive mechanism
- Intensity of the heat or caustic source
- Skin thickness
- Area being exposed
- Vascularity
- Age of patient
_______ burn: damage only to epidermis
Superficial
1st degree
________ partial-thickness burn: Epidermis is completely destroyed but dermal layer only sustains mild or moderate damage
Superficial partial-thickness
Ex. Hot liquids, solids, chemicals
(2nd degree)
______ partial-thickness: Damage of the dermis down into the reticular layer. Most of the nerve endings, hair follicles, and sweat glands will be injured because most of dermis is destroyed
Deep partial-thickness
*May get keloid or hypertrophic scars
(No corresponding degree)
[Type of burn]
Epidermis, dermis all destroyed, and some of subcutaneous fat layer
Appearance- Eschar covers, white to mahogany, charred
Full thickness
(3rd degree burn)
*scarring, typically requires grafts
[type of burn]
Epidermis, dermis, subcutaneous fat and some of muscle/bone possible
Subdermal
Ex. Electrical; color=yellow/ischemic
The rule of nines is used to establish the TBSA involved, what does TBSA stand for?
How does this classification work?
Total body surface burned
Divides the body into surface areas that are equal to 9% or equal multiples of 9%
Head, arm, trunk, leg, perineum
