NATURE OF “BEAST”
•
Pediatrics account for 15-25% of total
•
Trauma is approximately 50% of all
pediatric emergencies
emergent care patients.
•
•
•
Injury is the leading cause of death in
children
•
2003
Usually > 2 years old
More medical cases < 2 years old
MVC = 50%
Oklahoma EMSC Resource Center
2
NATURE OF “BEAST”
•
Almost 70% of major pediatric trauma
cases die due to severity of injury.
•
•
NOT a deficit in emergent care
When a child is injured, the whole
family is injured too!
•
2003
cont’d
> 40% divorce rate within 1 year after a
major trauma

Consider Possibility of
Child Abuse
When you see an injured child
•
•
•
2003
Common cause of injuries in children.
50% of second hospital visits for
these children result in death
Awareness of signs & symptoms of
abuse helps identify cases

General Principles of
Pediatric Trauma
•
Priorities are similar to adults
•
•
•
Children have certain key differences
•
•
•
•
2003
All roads lead to the A-B-C (D-E)’s
Start with “A”, not the most obvious
Different energy transfer due to size
Metabolism
Ability to respond to words & give history
History of accident may be critical in
determining intervention plan
Oklahoma EMSC Resource Center
6
Physical Differences
•
HEAD Is Larger
• Brain injury increased during impacts
• More leverage on neck
• Occiput forces neck into flexion while
lying flat
•
•
NECK Is Shorter
•
•
2003
Airway tends to buckle & close on adult spine
board without proper shoulder support
Causes different injury patterns
C2-C4 more common injuries
Oklahoma EMSC Resource Center
7
Physical Differences
•
CHEST More Pliable
•
•
•
•
Pulmonary contusion more likely
Diaphragm motion essential for
ventilation
Energy transmitted to chest organs
ABDOMINAL ORGANS Less Protection
•
•
•
2003
cont’d
Liver not covered by the rib cage
Less abdominal wall muscle mass
Less Sub-Q tissue to absorb energy
Oklahoma EMSC Resource Center
8
Energy Transfer Effects of Size
•
Children are Smaller
•
•
•
More force per square inch of body
Organs are closer together=multi-system
injury rule
Children are Softer
(More Flexible / Bouncy)
Bones don’t break but instead pass on
energy
• Internal organ damage without fractures
is more common
•
•
Larger Surface Area to Size Ratio
•
2003
Lose heat more rapidly
Oklahoma EMSC Resource Center
9
Metabolic Differences in Kids
•
Have Higher Metabolic Rates
Nearly Twice as Rapid O2 Consumption
• Increased Blood Flow
• More Frequent Feedings
• More Fluid Intake per Size Ratio
•
2003

10
Metabolic Differences
•
cont’d
Children “SHOCK OUT” Differently
•
Children Compensate Better INITIALLY
•
•
May show minimal signs & symptoms
Children have less reserves than adults
•
Platinum Half-Hour in Trauma Resuscitation
•
Rapid Intervention Critical
Once Reserves Exhausted
•
BAD THINGS HAPPEN!!!
2003
Oklahoma EMSC Resource Center
11
THE BAD THINGS
•
Decompensation can be rapid
•
•
A conscious, crying child can become
pulseless and apneic in less than 2
minutes
Once decompensated, may be too late
•
Limited Reserves are gone; whole system
collapses
RAPID & EARLY RECOGNITION &
INTERVENTION ARE CRITICAL!!!

Prepare Yourself
•
The first step in a cardiac arrest or
other critical situation is to:
Take your own pulse!!!
•
Assign roles ahead of time
Respiratory Management
• Spine Management
• Circulatory Management
• Hx, Equipment, etc.
•
2003

15
Careful Attention
•
Initial Assessment CRUCIAL
•
Don’t be distracted by the
blood and screams
A QUIET KID SHOULD
SCARE the @$% of
YOU!!!
•
2003
If practical, keep parents
with child to help reduce
child's fear

Brilliance vs. Basics
For every “BRILLIANT”
maneuver/diagnosis you
make which saves a life,
you’ll save 10 by just
doing a good, solid job.
STAY FOCUSED ON THE
BASICS IN THE HEAT OF
THE MOMENT!!!

Respiratory
AIRWAY: Patent with Precautions
• BREATHING: Respiratory Rate; too fast vs
too slow, Abnormal Sounds
•
•
•
A slow or irregular respiratory rate in a child is
an OMINOUS SIGN. (Bad JU JU)
Watch for the EFFORT NEEDED to BREATHE
•
Chest, neck, or abdominal muscle retractions
Flaring of the nostrils
•
Adventitious Sounds -Crackles, Crows, Grunts
•
(Rice Krispies, Rosters, Pigs)
2003
Oklahoma EMSC Resource Center
25
A=Airway: Control C-Spine
•
Unconscious kids can’t protect their
airway
Tongue most common obstruction
• Little airways are easily blocked
• JAW THRUST: Neutral Alignment for kids
includes Pad under the Shoulders
• May need Oral/Nasal Airway
•
•
Infants in first 30 days of life are
obligate nasal breathers
•
2003
May need to suction out blood/mucus
Oklahoma EMSC Resource Center
26
B=Breathing
•
All Children get Oxygen & LOTS OF IT
•
May need to assist with B-V-M
Good mask seal is the KEY to bagging
• Two people should bag when possible
• Avoid distending the stomach
•
•
•
Cricoid pressure / Easy does it
Distended stomach = less room for air in
lungs
Blue BAD 2003
Oxygen GOOD

Pediatric Trauma Messages
1. A little bleeding is a lot the smaller you are.
2. BP often maintained until very late in
hemorrhage by young patients because of
their overactive vasoconstrictive responses.

D=Disability: Neuro Eval
• Use the AVPU system first
– Avoid "lethargic“, "semi-conscious“, etc.
because everyone has different meanings
with these terms.
• Use the Pediatric Glasgow Coma Scale
– If time and circumstance permit
– Age and behavior adjusted
•
TBI’s need adequate oxygen !
Hyperventilate only if they deteriorate
• Otherwise High Flow O2
•
2003
Oklahoma EMSC Resource Center
31
E=Exposure
•
•
•
•
2003
Kids lose heat quickly
Keep them COVERED UP
Expose only as you need
If YOU are COMFORTABLE,
it’s probably TOO COLD for
them

Pediatric Trauma Score (PTS)
•
All components are scored:
•
•
•
•
Total score can range
•
•
•
•
2003
+2
+1
-1
+12, the best
- 6, the worst
The threshold score is 8
Anyone scoring < 8 send to Pediatric
Trauma Center
Oklahoma EMSC Resource Center
35
PTS Components
• SIZE
– The most obvious of all the components
– Automatically weights the infant-toddler
due to increased mortality associated to
their smaller size
• AIRWAY
– Assesses functionability and
management parameters
– The more toys it takes, the lower the
score
2003
Oklahoma EMSC Resource Center
36
PTS Components
•
SYSTOLIC B/P: Weighted to find the
evolving shock patient (50-90 mmHg).
•
New DOT EMT Basic uses capillary refill
as an indicator of cardiovascular status.
•
•
•
2003
cont’d
< 2sec, 2-4 sec, > 4 sec
Central vs Peripheral
PALS recommends use of peripheral and
central pulses as an indicator
Oklahoma EMSC Resource Center
37
PTS Components
cont’d
• MENTAL STATUS
– Any change in Mental Status warrants a lower
score
• SOFT TISSUE INJURY
– Surface Area / Volume Issue
• MUSCULO-SKELETAL INJURY/FX
– High incidence in kids
– Energy transmission instead of localized fracture
MULTI-SYSTEMS TRAUMA IS RULE
2003
Oklahoma EMSC Resource Center
38
Recognizing Signs of Shock
•
Early signs can be subtle
•
•
•
2003
May be minimal signs with under 20%
blood loss
50% and over blood loss usually
pulseless and unconscious (Read as DEAD)
Any injured kid who is Cool &
Tachycardic is in SHOCK until proven
otherwise!!!
Oklahoma EMSC Resource Center
39
Shock Recognition
cont’d
Altered mental status may be first sign of
shock
• Another early sign is DELAYED CAPILLARY
•
REFILL
•
Next comes a decrease in pulse pressure
•
•
Drop in Blood Pressure is a LATE SIGN
•
2003
Systolic minus Diastolic
Systolic should be > [ 70 + 2(age in years)] but
it rarely falls below this until 25-30% blood loss
Oklahoma EMSC Resource Center
40
Shock Recognition
•
cont’d
Anxiety, fear, and cold weather can all
mimic early shock
Increased heart rate
• Decreased capillary refill
• Pale, cool extremities
• Weak peripheral pulses
•
•
History alone can be a good enough
reason
•
2003
Remember the MOI

Infant Transport by EMS
• “Keep infants in car seats unless treatment
of injuries requires removal (IV, ETT, BVM,
control of hemorrhage). If they survived
the crash in an intact car seat, they are
usually better off to stay in it for the ride to
the hospital.”

Trauma Management
•
•
•
Kids are large headed and may have
cervical spine injury without evidence
Ideal immobilization is a hard collar,
spine board with pads & head-straps.
TBI’s need adequate oxygen!
Hyperventilate only if they deteriorate
• Otherwise High Flow O2

Pediatric Trauma Triage
Identifying a possible tool
to accomplish task…
2003
Oklahoma EMSC Resource Center
46
Pediatric Problems in Triage
• Children often not
triaged as well as adults
in traumatic MCI’s
• Currently no published
or widely utilized MultiCasualty Triage Tools
that take into account
physiology differences
between children &
adults
2003
Oklahoma EMSC Resource Center
47
Triage Problems
cont’d
• Pediatric Multi-Casualty triage may be
affected by the emotional states of
providers
• May be tendencies to upgrade triage
categories out of compassion or lack
of confidence in pediatric assessment
& intervention skills

Pediatric Problems with START
•
•
•
2003
Apneic child more likely to have a
primary respiratory problem than
adult
Perfusion may be maintained for a
short time & child may be salvageable
RR +/- 30 may either over-triage or
under-triage a child, depending on
age
Oklahoma EMSC Resource Center
54
Problems with START
•
Capillary refill may not adequately
reflect peripheral hemodynamic status
in a cool environment
•
•
2003
cont’d
In fact START has changed to reflect
peripheral pulse checks instead of cap
refill
Obeying commands may not be an
appropriate gauge of mental status
for younger children
Oklahoma EMSC Resource Center
55
JUMPSTART Goals
•
•
•
•
2003
Modify an existing tool for use with
children
Utilize decision points that are flexible
enough to serve children of all ages &
reflective of the unique points of
pediatric physiology
Reduce over- and under-triage
Accomplish triage for most patients
within 15 second/pt goal

•
2003
These children can be triaged using JUMPSTART
but should be fully screened
If all “DELAYED” criteria satisfied & without
significant external injuries, the child may be
classified as “AMBULATORY”
Pertinent pediatric physiology (specifically
airway) approaches that of adults by
approximately eight years of age
Oklahoma EMSC Resource Center
58
JUMPSTART Ambulatory
• Identify & direct all ambulatory
patients to designated GREEN area
for secondary triage & treatment
• Begin assessment of non-ambulatory
patients as you come to them
2003
Oklahoma EMSC Resource Center
59
JUMPSTART Breathing
• If breathing spontaneously, go on to
the next step, assessing respiratory
rate
• If apneic or with very irregular
breathing, open the airway using
standard positioning techniques
• If positioning results in resumption of
spontaneous respirations, tag the
patient IMMEDIATE & move on
2003
Oklahoma EMSC Resource Center
60
JUMPSTART Part
• If no breathing after airway open, check
peripheral pulse
– If no pulse, move on after tagging patient
DECEASED/NONSALVAGEABLE
• If peripheral pulse present, give 15 sec of
Mouth-to-Mask ventilations (about 5
breaths)
– If apnea persists, move on after tagging patient
DECEASED/NONSALVAGEABLE
• If breathing resumes after “JUMPSTART”,
tag patient IMMEDIATE & move on
2003
Oklahoma EMSC Resource Center
61
JUMPSTART Respiratory Rate
•
•
2003
If respiratory rate is 15-40/min (1
breath every 2-4 sec) assess perfusion
If respiratory rate is <15 or >40/min
(<1 breath every 4 sec or >1 breath
every 2 sec) or irregular, tag patient
as IMMEDIATE & move on
Oklahoma EMSC Resource Center
62
JUMPSTART Perfusion
•
•
2003
If palpable peripheral pulse, proceed
to assess mental status
If no peripheral pulse present (in the
least injured limb), tag patient
IMMEDIATE & move on
Oklahoma EMSC Resource Center
63
JUMPSTART Mental Status
• Use AVPU scale to assess
• If Alert, responsive to Verbal, or
appropriately responsive to Pain, tag
as DELAYED and move on
• If inappropriately responsive to Pain
or Unresponsive, tag as IMMEDIATE &
move on
2003
Oklahoma EMSC Resource Center
64
START/JUMPSTART Similarities
•
•
•
2003
As soon as a definitive triage category
determined further assessment STOPS
Ambulatory patients are immediately
moved away for secondary triage
To be in the DELAYED category pt’s
must have adequate respirations &
perfusion & mental status that is
unlikely to compromise the airway
Oklahoma EMSC Resource Center
65
START/JUMPSTART
Differences
•
Apneic children are rapidly assessed for
sustained circulation
•
•
•
Respiratory rates are adjusted
Peripheral pulse is substituted for Cap
Refill
•
•
2003
Apneic children with circulation receive a
brief ventilatory trial as an additional airway
opening & stimulating maneuver
This is now done in START too
AVPU is used to assess mental status

Disadvantages
•
•
•
•
•
2003
Extra steps for apneic children add
time to the triage process
Mouth-to-Mask ventilation increases
the risk of cross-contamination
between patients
Additional equipment must be carried
