Objectives • To understand the structured approach to the child with burns • To learn how to identify the severity of burns in a child • To introduce the skills and equipment used for the resuscitation of a child with severe burns
Epidemiology 755 pts. ≤15 yoa in 14/17 Burns Units in A & NZ Figures by courtesy of Bi-NBR 2010-2011 year Figures from Bi-NBR
Epidemiology • Causes of Burns • Overall • 55% are scalds • 21% are contact • 14% are flame • Scalds are commonest cause up to 11 yoa • 78% of scalds occur in the usual place of residence • >10 yoa flame burns are commonest cause
Pathophysiology Severity of Injury • Temperature • Duration of contact • % of Body Surface Area burnt
Immediate Priorities A irway nd C spine control B reathing C irculation
Airway management must not be delayed Airway Compromise
Inhalational Injury • Systemic poisoning • CO & HCN: usual cause of death at the scene • Supraglottic injury • Swelling within hours causing obstruction • Infraglottic injury • Smoke particles cause chemical response >1-3 days SMOKE IS HOT
Inhalational Injury 45% of patients with flame burns above the clavicles have inhalation injury Watch for progressive signs SMOKE IS HOT History of exposure Soot in mouth Carbonaceous sputum Singed facial hair Hoarseness or cough Stridor
Suspicion Early intervention Airway Management
Breathing • Associated chest injuries • Circumferential burns Small children use the diaphragm so a burn of the front & sides of the trunk can impair ventilation.
Circulation • Fluid loss is obligatory, max. 8 hrs, continues 48 hrs • Hypovolaemia from burns occurs relatively late • If shocked early, look elsewhere for a cause
Additional fluid Resuscitation • Burn (%) x Weight (kg) x 4 ml per day • Calculated from the time of the burn • Half in first 8 hours • Hartmann’s Maintenance – as usual over 24 hours
Circulation • Assess fluid requirements by urine output • 0.5 - 2 ml / kg / hr • Ideally 0.5-1 ml/kg/hr • Avoid overhydration • >2 ml/kg/hr if haemochromogenuria Formulae are only guides
Exposure BURNT CHILDREN LOSE HEAT VERY RAPIDLY
Any injury can occur Secondary Survey • Blast • Falls • MVAs • Falling objects • Escape Associated injuries may be obvious or hidden
Burn Assessment • Surface area • % of Body Surface Area (%BSA) • Depth • Describe anatomically • Site • Involves “special” areas?
Surface Area Assessment Paediatric BSA chart Child’s hand (palm and adducted fingers) is 1% BSA
Surface Area Assessment For simplicity use “Rule of 9s” In adult 1 x 9 for h & n, each arm 2 x 9 for each lower limb 4 x 9 for trunk In Infant 1 X 9 for each arm. 2 X 9 for head 14% each lower limb 4 X 9 for trunk Take 1% off head & add to legs for each year of life >1
Depth • Superficial - Pink - Blistered • Base blanches on pressure • Refills on release
Depth • Mid dermal – dark, mottled red, non-blanching • Deep - White/charred - Leathery Early depth assessment is inaccurate
Wound Care • Remove FBs and wash • Cling film loosely applied • Elevate • Ointments, creams or dressings ONLY as part of definitive care or transfer delayed (discuss).
OpiatesIV Opiates IM Analgesia
AVOID HYPOTHERMIA Cooling Therapy Flowing water 8-25°C Most effective for partial thickness Continue 20 minutes Excellent pain relief
Non Accidental Injury? • “Glove and stocking” scalds • Artefact shape of burn • Absence of splash marks • Inconsistency of history and examination • Delay in presentation • Signs of other injuries • Repeated presentation • Witness to event not at ED
Transfer criteria (adapted from EMSB) • Adult – total > 10 % or full thickness >5% • Child - total > 5 % • Special areas: Face, hands, feet, perineum and major joints • Circumferential burns • Inhalational injury • Chemical, radiation or electrical burns • Suspicion of non accidental injury • Patient with pre-existing medical disorders which may complicate management, prolong recovery or affect mortality • Associated significant trauma

Burns and scaldsSummary A Treat airway compromise earlyTreat shock and resuscitateLook for associated injuriesUse IV analgesia as appropriate Care for woundsRefer appropriatelyQuality transfer C B
Epidemiology • The leading cause for accidental death of children worldwide • NZ 18 deaths per year 28 if include up to 19 yr cf Eng & Wales 34 in 1998 • 62 admissions per year > 24 h
Management • Prevention • Effective, early basic life support • Assume cervical spine injury • Handle gently if hypothermic
Management • Intubate to prevent aspiration • Gastric drainage to remove swallowed water • Measure core temperature and treat hypothermia • Full trauma assessment for other injuries
HypothermiaManagement External Rewarming • Remove wet clothing • Wrap warmly • Radiant heat • Warm air system • Direct heat Core Rewarming • IV fluids to 39oC • Ventilator gases to 42oC • Gastric/bladder/ peritoneal/pleural lavage at 42o C • Extra-corporeal rewarming with by-pass
HypothermiaManagement of cardiac arrest • Active core re-warming vital • No initial medications until core >30o C • Initial defibrillating shocks, but no repeat till core >30o C • Volume expansion may be needed • Continue to resuscitate until expert advice obtained
DrowningPrognostic indicators No single factor reliably predicts outcome • Immersion time • Time to first respiratory effort • Core temperature • Persisting coma • The clinical course is determined by hypoxic-ischaemic injury and adequate CPR
