burns 1/22

Question 1

Burns cause
Hemodynamic instability due to ??? influences numerous physiologic changes that occur secondary to severe burn injuries.
what body systems can it effect?

Answer 1

capillary disruption
This potentially life-threatening shift can result in severe cardiovascular, pulmonary, metabolic, and electrolyte impairments before a significant change in blood volume is even detected.

Question 2

burns cause

hyper/hypothermia?

Answer 2

Hypothermia (i.e., abnormal decrease in body temperature) as a result of the high metabolic demands associated with the traumatic injury and significant impairment of the integumentary system’s thermoregulation capabilities.

Question 3

burns cause
poly/reduced uria?
what does it indicate?

Answer 3

Because of the significant hemostatic disruption of body systems, the patient will typically have reduced urine output.
-patient’s urine output is closely monitored as an indicator of renal function and fluid replacement efforts.

Question 4

burns cause
hyper/hypovolemia?
what does it mean?

Answer 4

Hypovolemia refers to a reduction in blood plasma volume resulting in decreased blood and oxygen perfusion to the body.
- acute threat of hypovolemia is high for patients who have sustained severe burn injuries and is considered to be life-threatening without immediate medical attention

Question 5

Typical hand splints positioning after burn so that contracture formation will not occur.

• wrist
• MCP
• IP
• thumb

Answer 5

wrist extension
metacarpophalangeal joint 90deg flexion
interphalangeal joint extension
thumb abduction.

Question 6

considerations for positioning patient after burn

Answer 6

• primary goal is to prevent contractures due to hypertrophic scarring and immobility.
• with consideration of future function, position in the direction opposite the anticipated direction of contracture.

Question 7

ideal position for LE post burn

Answer 7

supine 
hip neutral
knees extended 
toes pointing toward the ceiling, DF  
reduces the likelihood of lower extremity contracture.
