Week 14: Trauma ASYNCHRONOUS
Emergency Care Situations
Trauma: “an injury to human tissues and organs resulting from the transfer of energy from the
environment” (TMCC Provider Manual, 2005, p. 11).
Minor versus Major Traumas:
Minor Trauma: Major or Multiple Trauma:
● Causes injury to one part or system. ● Serious single-system injury or
● It is treated in practitioners' offices, multiple-system trauma; requires
hospitals or ERs. immediate intervention with a focus on
survival.
● Most often, it results from MVCs and
requires long periods in ICUs.
Mechanisms of Injury:
Energy Agent: Mechanism of Injury:
Mechanical (Kinetic) ● Motor vehicle crashes
● Firearms, falls, assaults
● Motorcycle crashes
Thermal ● Heat, steam, fire
Chemical ● Plant and animal toxins
● Chemical substances
Electrical ● Lightning
● Exposure to wires, plugs
Radiant ● Sun rays
● Sound waves
● Electromagnetic waves
● Radioactive emissions
Peaks of Trauma:
heart
1. Death occurs within sec/min of trauma; Catastrophic pleed-brain,
2. Death min/hours after initial trauma; slow bleed intracranial bleeding
-
3. Hours/days/weeks later. infection immobility , clotting

Special Age-Considerations:
seats + being in back ↓ risk.
MVCs and Children: most children die as passengers , car
Pedestrians : sayo-run anto road

Trauma in Older Population:
MVCs , fells and burns make up a total of 8030 of injuries in this population
Risk Factors :
#
history of falls
anemia
psychotropic drug use
arthritis
LE weakness
Stroke
balance problems
cognitive impairments
Orthostatic hypotension
dizziness
