Introduction
In the mid 1960s trauma was identified as
“the neglected disease of modern society.”
– Resulted in establishment of growth of EMS
Current research shows that often the skills
of EMS professionals worsen the outcome
of the trauma patient.
– Must ensure that our practices are current and
BENEFIT our patients
– Must function as part of an integrated health
care delivery team

Injury Prevention
Prevention is the GREATEST key to reduce
injury.
– Injury prevention is the future of EMS.
“Let’s not meet by accident”

Shock Trauma Resuscitation
(1 of 5)
Hypothermia
– Due to sympathetic effects.
– Body begins to conserve energy.
Redirects blood supply to internal organs.
Slows temperature regulation activities.

Body Splinting
– Splinting must be effective and performed
quickly.
– Best accomplished by aligning limbs and
securing body on long spine board.
Limits movement of all extremities and spine.
Movement and immobilization must be
coordinated.

Shock Trauma Resuscitation
Special Patients: Pediatrics (4 of 6)
Compensatory Mechanisms
– Vibrant cardiovascular system
Greater compensation during shock
>25% of blood volume before signs develop
>50% of blood volume before compensation fails
Rapid deterioration once compensation fails
Rapid progression to irreversible shock
Loss of vital signs
– Respiratory system has less reserves
Less able to tolerate stressors
Muscles tire quickly due to faster respirations

Air Medical Transport (5 of 7)
Flight Physiology
– Higher altitude = less pressure on patient
Internally trapped air exerts more pressure.
Conditions that can worsen:
Asthma
COPD
Tension pneumothorax
Interventions that can worsen:
PASG can increase in pressure exerted.
Cuffed ET tubes expand.
Pressure infusing bags exert more pressure.
Air splints exert more pressure.

Air Medical Transport (6 of 7)
Flight Considerations
– Confined working area.
– Limited ability to perform procedures.
Intubation
Chest decompression
CPR
Application of PASG
– Fully immobilize patient prior to transport.
– Ensure that any ALS interventions are
patent and secured.

Air Medical Transport (7 of 7)
Air Medical Patient Preparation
– Assure maximal oxygenation.
– Assure maximal ventilation.
– Administer high-flow oxygen.
Consider intubation or RSI.
If patient airway status is marginal or deteriorating.
– Assess for pneumothorax.
Decompress prior to loading.
– Establish 2 large-bore Ivs.
– Provide flight crew with complete and
abbreviated patient report.

Research and Trauma
Research must occur to assure that
EMS uses procedures beneficial to
patient outcomes.
– Outcomes include discharge from
hospital.
NOT delivering a “live” patient to the hospital.
All EMS personnel must participate to
ensure optimal patient care.
