Burns- Refers to injuries that result
from direct contact with or
exposure to any thermal,
chemical, electrical or
radiation source.
- Destruction of the layers skin or other body parts causing loss of intracellular fluid and electrolytes.
- Involves painful treatment and long period
of rehabilitation
CAUSES:
• CHEMICAL• ELECTRICAL• MECHANICAL• RADIATION• THERMAL
Smoke inhalation
-Occurs when smoke(particular products of fire, gases & superheated air)
causes respiratory tissue damage
Classification of Burns
Burn injuries – described according to the a. DEPTH of the injury b. extent of surface area injured
Classification according to DEPTH
Superficial-Partial Thickness
“1st degree burn” Epidermis (upper dermis) Reddened; blanches with pressure Dry or with minimal or no edema Possible blisters (may be) painful
Soothed by cooling No scarring; Peeling Recovery in a week
Classification according to DEPTH
Deep Partial Thickness
“2nd degree burn” Epidermis & entire dermis Blistered; mottled red base
Edema Painful Sensitive to cold air Depigmentation contractures Recovery in 2-4 weeks
Classification according to DEPTH
Full-Thickness
“3rd degree burn” Epidermis; entire dermis & subcutaneous tissue Dry, pale white, leathery or charred

The nurse is planning care for an adult man who is admitted with severe flame burns. Nursing care planning is based on the knowledge that the first 24-48 hours post-burn are characterized by:
a. An increase in the total volume of intravascular plasma.b. Excessive renal perfusion with diuresis.c. Fluid shift from interstitial spaces to plasma.d. Fluid shift from plasma to interstitial spaces.

CONCESUS FORMULA- Lactated Ringer’s Solution (other balanced saline solution)- 2 – 4 ml x kg body weight x % TBSA burned- half to be given in first 8 hours- remaining half to be given over the next 16 hours
I. Emergent Phase
The physician has ordered 3, 600 milliliters of intravenous fluid to be given during the first 8 hours at a rate of 450 ml/hr. The nurse should recognize that the :
a. Amount is within the normal range for a burned client b. Physician’s orders should be questioned as soon as possible c. Physician probably means 45 ml/hrd. Maximum amount of intravenous fluid for a 24-hour period is 4, 000 milliliters

Weight – 50kg, TBSA burned – 36%
