Primary & Secondary Survey
 Primary survey:
 Quick, initial patient assessment to identify lifethreatening injuries
 Occurs with active resuscitation
 Secondary survey:
 More detailed assessment of injuries
Primary Survey
 A,B,C,D,E
 Every trauma patient should arrive boarded
and C-spine immobilized
 Collar for school-age/adolescents
 Rolls and tape for infants/toddlers
 Immediate vitals signs

 A = Airway & C-Spine Precautions
 B = Breathing
 C = Circulation
 D = Disability
 E = Exposure
A: Airway & C-Spine Protection
 Check for airway patency and clear
secretions
 If already intubated, confirm ETT position
with:
 Chest x-ray, End tidal CO2, Oxygen saturation,
Auscultate the lungs for equal air entry, Take a look with
a laryngoscope
 Ensure adequate C-spine protection
B: Breathing
 Check for
adequacy of
breathing
 Effort, breath
sounds, oxygenation
 Apply oxygen by
facemask or blow
by.
 Assess need for
intubation
C: Circulation
 Most common cause of shock in
pediatrics = hypovolemia
 2 large bore IV’s started
 Xmatch or Type and screen ordered
 20 ml/kg IV crystalloid bolus (x 3 then
PRBC’s)
 Look for obvious and non-obvious
sources of bleeding
D: Disability
E: Exposure
 Assess all surface areas
 Log-roll with using spinal precautions
 Examine the spine: note step deformities or pain
 Assess rectal tone and sensation
 Check for vaginal/urethral bleeding
 Prevent hypothermia
 Keep trauma room warm, use blankets and overhead
warmer for infants

Head Trauma
Head Trauma
 Leading cause of death & disability in childhood
 Mortality rate 20-30%
 0-14y age range TBI = 400 000 visits/year to ED
 1-2% of all comers to ED
 Only 3-5% of those with intracranial injury
 <1% of above require neurosurgery
Head Trauma
 Causes:
 Infancy: NAT, falls
 Childhood: MVA, pedestrian, bicycle
 Adolescence: MVA, pedestrian, bikes/boards, violence
 Sex:
 M = F ~ 5 yo
 M > F > 5 yo (2-5:1)
Head Trauma
Common Signs & Symptoms of
Increased ICP in Children
Acute Medical Management of
Raised ICP
 Position head of bed at 300
 Mannitol IV 20% = 1g/kg per dose
 Must chase with bolus of NS
 Prevent hypoxia and hypotension
 Control external hemorrhage
 Maintain C-spine precautions
 Early intubation using RSI to prevent
complications
Head Injury
 Definitive management dependant on lesion
and examination
 Early involvement of neurosurgery
recommended
 Admission for observation and closely
monitoring for deterioration a must
 Consider need for IV Mannitol early for
raised intracranial pressure
Chest Trauma
Chest/Thoracic Trauma
 Accounts for 4.5 – 8% pediatric trauma
 2nd most common cause of mortality in
pediatric trauma
 Most common causes:
 Motor vehicle accidents (MVA’s)
 Pedestrians
 Unrestrained passengers
 Bicycle riders
 Falls
Chest/Thoracic Trauma
 Pediatric thoracic trauma higher risk:
 More compliant chest wall
 Increased mediastinal mobility
 Tension pneumothorax develops quicker
 Children more prone to hypoxia
 Less ability to compensate for hypovolemia
Chest/Thoracic Trauma
 Blunt versus penetrating
 Blunt:
 High energy trauma affects internal organs
 Deceleration mechanisms affect mediastinal structures
 Penetrating:
 Disrupts underlying structures
 Do not remove penetrating objects! Must remove in a
controlled setting (Operating Room)
Chest/Thoracic Trauma
Tension Pneumothorax
 Hypotension, distended jugular veins, shifted
heart sounds, hyper-resonance, trachea not
midline
 Treatment:
 Emergent needle decompression = Large bore IV
inserted over rib in 2nd ICS after sterile drape/prep if
possible
 Chest tube needed for definitive management
Chest Tube Insertion
Abdominal Trauma
Abdominal Trauma
 3rd leading cause of traumatic death
 Often unrecognized in children
 Consider abdominal injury in the following:
Sign
Possible Injuries
Seatbelt Injury
Small bowel injury
Chance fracture
Handlebar injury
Duodenal hematoma
Pancreatic injury
Sport related injury
Spleen, kidney, bowel
Abdominal Trauma
Abdominal Trauma
 If unstable vitals, indication for OR
 FAST to look for free fluid in the abdomen.
 IV contrast enhanced CT gold standard for
diagnosis of stable patient
 Definitive management dependant upon
specific organ injured
Burns/Thermal Injury
Burns/Thermal Injury
 70% pediatric burns secondary to hot liquid
 Up to 20% burns in younger children secondary
to abuse or neglect
 Consider inhalational injury and need for EARLY
intubation if not secondary to liquid
 Hoarseness
 Black sputum
 Facial burn
 Accident in closed area

 Estimating Burn Size
Palm of patient’s hand =
~ 1% BSA
Burn/Thermal Injury:
Management
 ABCDE’s
 Consider early intubation if airway involvement
 Tetanus prophylaxis and ANALGESIA
 Fluid resuscitation mainstay of treatment
 Parkland Resuscitation Formula: using Ringer’s Lactate
 Give 4ml/kg/%TBSA
 First half of resuscitation fluids (AS WELL AS
MAINTENANCE FLUIDS) over first 8 hours
 Second half over following 16 hours
 u/o goal: 1-2 ml/kg/hour
Burn/Thermal Injury
 Consider referral to a burn centre if:
 Inhalational injury
 Burn size >10% TBSA in child <10yo
 Burn size >20% in any patient
 Full-thickness burns >5% TBSA
 Burn involving hands/feet/face/perineum
 Mutiple comorbidities
 NAT
 Chemical/Electrical injury
Submersion Injuries
Submersion Injuries
 500 000 deaths due to drowning per year
worldwide
 >50% drowning victims <5yo
 Fatality is highest in children <5yo
 M>F
 Most common cause of cardiac arrest in
children
Submersion Injury
 Most common sites of drowning:
 <1yo : Bathtubs (55%)
 1 – 4yo : Pools (56%)
 >4yo : Freshwater (63%)
 Definition of drowning versus Near
Drowning:
 Drowning = death within 24h of suffocation from
submersion in liquid
 Near Drowning/Submersion injury = survival >24h past
event
Submersion Injury
 Pathophysiology of drowning:
 Accidental submersion
 Loss of normal breathing pattern
 Possible laryngospasm
 Pulmonary aspiration/breath-holding/apnea
 Hypoxemia:
 Low O2, hypercarbia, acidosis
 End-organ damage – circulatory arrest
Submersion Injury
 ABCDE’s
 Consider early intubation
 Always consider C-spine immobilization
 0.5% submersion victims have c-spine injury
 Remove wet clothing
 Treat hypothermia
Poor Prognostic signs
 Prolonged submersion >25 minutes
 Delay in CPR initiation
 Resuscitation >25 minutes
 pH <7.1
 Pulseless, cardiac arrest on arrival to emergency department
 Elevated blood glucose on arrival
 Dilated and fixed pupils on arrival
 Abnormal initial CT of brain
 Initial GCS of <5
Conclusion
 Pediatric trauma and injury are preventable
conditions
 Principles of management should always
include a well orchestrated primary and
secondary survey
 Never hesitate to admit for observation, ask
for help or consult specialty services -the
earlier the better.
