Lesson 9
Special Considerations
Overview (1 of 2)
• Pediatrics
• Geriatrics
• Multiple patient
situations
• Trauma
resuscitation issues
Overview (2 of 2)
• In the United States, trauma is the most
common cause of death in children
• The elderly are the fastest growing subset
in our population
Our Bodies Change Over Time
• There are anatomic
differences between
infants, children, and
adults
• Body systems continue
to develop and mature
in the young
• Aging body systems
show signs of
dysfunction
ABCs
• Airway
– Anatomic differences
• Age and size of the patient affects equipment
choice
• Breathing
– Respiratory complications
• Circulation
– Pediatric patients compensate well but
deteriorate quickly
– Geriatric patients compensate poorly and may
be on medications that affect pulse and blood
pressure
Anatomy and Physiology:
Pediatric (1 of 5)
• Less body fat, increased elasticity of
connective tissue, and close proximity of
organs to the body surface impair
dissipation of energy applied
• Incomplete calcification of bones and
active growth centers limit absorption of
energy and can increase potential for
injury
Anatomy and Physiology:
Pediatric (2 of 5)
• Larger head and tongue
– Special attention to positioning
– Potential for airway obstruction
• Conical-shaped trachea
– Uncuffed versus endotracheal tubes
• Shorter trachea
– Danger of main stem intubation
Anatomy and Physiology:
Pediatric (3 of 5)
Anatomy and Physiology:
Pediatric (4 of 5)
• Respiratory concerns
– Hypoventilation and hypoxia are more likely
than hypovolemia and hypotension
– Injured children can rapidly deteriorate from
labored breathing to tachypnea and progress
to apnea from exhaustion
Anatomy and Physiology:
Pediatric (5 of 5)
• Shock
– Most pediatric injuries
do not cause
immediate
exsanguination
– Blood pressure is a
poor indicator of blood
loss and peripheral
perfusion
– Children remain in
compensated shock
longer than adults, but
decline very rapidly
Managing Pediatric Patients
(1 of 5)
• Airway and breathing
– Ensure airway patency
– Provide supplemental oxygen
– Assist ventilations when indicated
• A bag-mask device may be adequate
• Intubate only if bag-mask device is not effective
– Tachypnea and increased effort to breathe
can indicate shock
– Monitor for signs of respiratory fatigue
Managing Pediatric Patients
(2 of 5)
• Circulation
– Evaluate skin color, temperature, and
peripheral perfusion
– Pediatric patients may not show signs of
hypotension until 30% of volume is lost
– Decreasing pulse rate in the face of shock is
an ominous sign
– Fluid replacement
• 20 ml/kg bolus
• May repeat based on clinical response
Managing Pediatric Patients
(3 of 5)
• Disability
– Glasgow Coma Scale (GCS)
• Use the pediatric GCS for preverbal children
– Level of consciousness (LOC) is most
important factor
• A child who is lethargic or asleep rather than upset
may indicate hypoperfusion or traumatic brain
injury (TBI)

•
Use appropriately sized equipment
Preserve body heat
Frequently reassess patients
Transport:
– In an age-appropriate device
– To an appropriate facility
Anatomy and Physiology:
Geriatric (1 of 4)
• Overview
– The body gradually loses its ability to maintain
homeostasis
– Pre-existing conditions can increase mortality
from less severe injuries
– Malnourishment is common
– Geriatric patients may have:
• Slower cognitive responses
• Degenerative diseases
• Decline in sensory acuity
Anatomy and Physiology:
Geriatric (2 of 4)
• Airway and breathing
– Ventilatory function declines
• Increased stiffness in chest wall
• Alveolar surface decreases
• Decreased ability to saturate hemoglobin with
oxygen
• Circulation
– Pre-existing diseases may compromise
compensatory mechanisms
Anatomy and Physiology:
Geriatric (3 of 4)
• Disability
– Slower response to stimuli
– Declining mental and psychomotor activity
– Sensory changes
•

•
Hearing
Vision
Pain
Temperature regulation
Anatomy and Physiology:
Geriatric (4 of 4)
• Musculoskeletal
– Loss of height due to
dehydration of vertebral
discs
– Compressed spinal cord due
to narrowing of spinal canal
– Kyphosis
– Porous and brittle bones
– Loss of muscle mass
– Loss of range of motion

Management of Geriatric
Patients
• Airway and breathing
– Loss of soft tissue and teeth may make face
mask seal difficult
• Circulation
– Administer fluid
with caution
• Possibility of
fluid overload

Burns
Burns: Overview
• All burns are serious, regardless of size
• Burns are not just a skin injury
– Large burns involve multiple organ systems
• Smoke inhalation can be life-threatening
– It is often more dangerous than the burn itself
• Children account for 20% of all burn
victims
– Consider the possibility of intentional injury
(abuse)
Burn Assessment
(1 of 4)
• Depth of injury
– Superficial (first-degree)
– Partial-thickness (second-degree)
• Superficial
• Deep
– Full-thickness (third- and fourth-degree)
– Burn depth may evolve over time

Burn Assessment
(4 of 4)
• Extent of burn
(burn size
estimation)
– Percent of
body surface
area (BSA)
involved
• Rule of nines
Burn Management:
Primary Assessment (1 of 3)
• Conduct the primary assessment
— Airway occlusion may occur as swelling
progresses
•
Consider early airway intervention
— Breathing may become compromised from
chest wall eschar or toxic pulmonary injury
•
Monitor ventilatory rate, SpO2, and ETCO2
Burn Management:
Primary Assessment (2 of 3)
• Circulatory status may be compromised
as fluid leaks into damaged tissue
causing swelling and hypotension
– Ensure IV access and fluid replacement
Burn Management:
Primary Assessment (3 of 3)
• Disability
—
Altered mentation suggests hypotension or
hypoxia
• Expose
—
—
Allows for complete assessment but may
lead to loss of body temperature
Cover patient upon completion of
assessment
Burn Management
(1 of 3)
• Specific burn therapy
– Stop any ongoing burning
– Cover with dry, sterile nonadherent dressing
(sheet)
• Do not use any ointments or other topical
antibiotic
Burn Management
(2 of 3)
• Specific burn therapy:
– Initiate fluid administration
• Parkland formula: total fluid in first 24 hours 
(2–4 ml)(body weight in kg)(% BSA burned)
– Half of total fluid should be given in the first 8 hours after
burn
– Second half of total fluid should be given in the next 16
hours after burn
– Adults receive lactated Ringer’s
– Pediatric patients receive 5% dextrose in lactated
Ringer’s
Burn Management
(3 of 3)
• Analgesia
– Adequate pain relief is critical
– Narcotic analgesics are indicated for
significant burns
– Ice is not a proper analgesic
• Leads to hypothermia
• May increase the overall size and depth of burn
• Transport to burn center as indicated
Extended or Delayed Transport
• Need to provide care for extended time
period
• Continue to provide same type and level of
care
• Be cautious of and monitor for:
– Hyperventilation
– Fluid overload
– Body heat loss
• Continually reassess the patient
Multiple Patient Situations
Multiple Patient Situations
(1 of 2)
• A multiple patient scenario occurs each
time there is more than one patient
• Are there sufficient resources available on
scene to manage all patients?
– Triage is used primarily when the number of
patients exceeds the immediate treatment
and/or transport capacity
Multiple Patient Situations
(2 of 2)
• Transport only one critical patient per
ambulance (ideally)
• When possible, distribute patients to all
available hospitals
– Avoid overloading the closest hospital when
possible
Trauma Resuscitation Issues
Trauma Resuscitation Issues
(1 of 3)
• It may be allowable to withhold or
terminate resuscitation efforts in:
– Injuries not compatible
with life
– Pulseless and nonbreathing
blunt trauma victims
– Trauma patients with
witnessed cardiopulmonary
arrest and 15 minutes of
unsuccessful resuscitation and CPR

Trauma Resuscitation Issues
(2 of 3)
• Special consideration in trauma
resuscitation must be given to victims who
have greater likelihood of survival,
including:
– Hypothermia
– Immersion incidents
– Lightning strike
– Other situations as defined by local protocol
Trauma Resuscitation Issues
(3 of 3)
• In many EMS systems, online medical control
is necessary to confirm the decision to
terminate resuscitation efforts
• Policies and protocols for termination of
resuscitation efforts:
– Should be developed and implemented under the
guidance of the EMS system’s medical director
– Should include notification of the appropriate law
enforcement agencies and medical examiner
• EMS providers should have access to
resources for debriefing and counseling as
needed
Summary
• EMS providers will
often encounter
special patient
populations and
situations
• Awareness of the
unique aspects of
each will optimize
patient management
and outcome
