10 things you must know about Pediatric Trauma Ahmad Althekair, MD Fellow, Pediatrics Emergency Medicine Hospital for sick children Objectives 1. RSI 2. When to EFAST 3. X-ray vs. CT in C-spine injury 4. To pan-CT or not 5. Thermal injures 6. Envenomation 7. NAT Epidemiology Leading cause of death above the age of infancy 25% of traumatic injuries occur in children Epidemiology Most common causes of injury-related deaths: Traumatic brain injury Motor vehicle crashes Submersion injury Homicide Suicide Fires Epidemiology > 700 000 injury-related deaths world-wide occur in the <15 year old age group (in 2002) Bimodal distribution in injury death rates: Children and Teens Teens are at increased risk due to: Increased exposure to hazards Infants: Are at higher risk of inflicted trauma Trauma Triage Scores • RTS Trauma Triage Scores • PTS Trauma Triage Scores • ISS 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,B,C,D,Es 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 Primary Survey Goals IDENTIFY INTERVENE Airway Inadequate airway Secure and protect Breathing Apnea Positive pressure ventilation Hypoxia Supplemental oxygen Tension pneumothorax Needle decompression, chest tube Massive hemothorax Chest tube Open pneumothorax Occlusive dressing, chest tube Primary Survey Goals IDENTIFY INTERVENE Circulation Hypovolemic shock Fluid bolus, blood products Pericardial tamponade Fluid bolus, pericardiocentesis, thoracotomy Cardiac Arrest Chest compressions, thoracotomy if penetrating trauma Disability Spinal cord injury Immobilization Cerebral herniation Hyperventilation, mannitol Exposure Hypothermia Warmed fluid, external warming Exsanguinating hemorrhage Direct pressure Adjuncts to Primary Survey Access: IV vs. IO Monitor: Cardiorespiratory/Pulse oximetry. Trauma bloodwork CBC, electrolytes, blood gas, creatinine, BUN, PT/PTT, Xmatch, liver function studies, lipase or amylase BHCG if female of child-bearing age Imaging Prior to Secondary Survey Xrays: CXR (AP only) Pelvis (AP only) C-spine: lateral, AP and odontoid if cooperative FAST 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 Burns Burn Assessment Depth 1st degree: superficial (epidermis) 2nd degree: superficial or deep partial thickness (dermis) 3rd degree: full thickness (beyond dermis) Burn/Thermal Injury Burn Assessment Time to healing Appearance Surface Sensation 1st degree Pink or red Dry Painful Days Superficial 2nd degree Pink, clear blisters Moist Painful 14–21 days Deep 2nd degree Pink, hemorrhagic blisters, red Moist Painful Weeks, or may progress to 3rd degree and require graft 3rd degree White, brown Dry, leathery Insensate Requires excision 4th degree Brown, charred Dry Insensate Requires excision Burn/Thermal Injury 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.
