Pediatric Trauma Review Focus on chest trauma and a JumpSTART Review Silver Cross Hospital EMS May 2014 CE UNIVERSITY OF NEW MEXICO

Epidemiology - General Trauma is the leading cause of death between the ages of 1-18 Injury accounts for 5% of infant deaths 47% of these deaths are related to MVCs With rates higher in those >13yo 13% of deaths in those 1-14yo were a result of homicide In the school age group Pedestrian injuries and bike injuries predominate UNIVERSITY OF NEW MEXICO

Pediatric Head Injury #1 cause of death due to trauma ~2700 deaths/year 450,000 children present to EDs each year with head injury 90% suffer from minor injuries Perinatal period Birth injuries 1-4 years old Falls School age Pedestrian or bike injuries Adolescence MVA UNIVERSITY OF NEW MEXICO

Children have larger heads than adults in relation to their body The chance that it is hit in a traumatic event is larger Head is heavy Different acceleration dynamics UNIVERSITY OF NEW MEXICO

At birth, face to cranium ratio is 1:8, adult ratio is 1:2.5 Makes it more likely skull is hit in younger children Lack of pneumatization of sinuses is associated with more rigidity and less plasticity of facial skeleton Increases transfer of forces directly to brain UNIVERSITY OF NEW MEXICO

Pediatric Spine Injury 18.1 spinal cord injuries per million children 1300 new cases a year 60-80% of injuries occur at the cervical level Adults have a 30-40% incidence Children <8 yo More likely to sustain high cervical (C1-C3) injuries UNIVERSITY OF NEW MEXICO

Pediatric Thoracic Trauma #2 cause of trauma related mortality In isolation, thoracic trauma carries a 5% mortality 25% when combined with abdominal injury 40% with head and abdominal injury UNIVERSITY OF NEW MEXICO

Anatomic Considerations Incomplete ossification of ribs allows anterior ribs to be compressed to meet posterior Pulmonary contusions are common, rib fractures uncommon Pulmonary contusions are most common thoracic injury in traumatized children Trachea is narrow, short, more compressible Great vessel and cardiac injury are rare in children UNIVERSITY OF NEW MEXICO

Anatomic Considerations Commotio Cordis is a unique consequence of pediatric thoracic trauma Abrupt strike to the chest leads to V-Fib and arrest UNIVERSITY OF NEW MEXICO

Pericardial tamponade: Pericardial tamponade is caused by blunt or penetrating trauma to the heart. Blood leaks into the pericardial sac, causing compression of the heart. As the volume of blood in sac increases, the compression of the heart becomes more pronounced. This causes cardiac output to fall dramatically and leads to a backup of volume in the venous system. UNIVERSITY OF NEW MEXICO

Pericardial Tamponade Signs of pericardial tamponade are: Broken ribs or penetrations to chest wall. Dyspnea/Cyanosis Neck vein distention Weak, thready pulse Decreasing blood pressure Shock Narrowing pulse pressure UNIVERSITY OF NEW MEXICO

Pericardial Tamponade Treatment: Oxygenation Assisted ventilation as necessary IV therapy EKG monitoring Rapid transport to nearest I Trauma facility UNIVERSITY OF NEW MEXICO

Cardiac Contusion: Cardiac contusion is a common injury following severe blunt trauma to the chest. It usually occurs when the heart is compressed between the sternum and the spinal column. Severe contusions may include rupture of the heart wall. Most commonly, the right ventricle is injured, as it lays directly beneath the sternum. UNIVERSITY OF NEW MEXICO

Cardiac contusion Signs of cardiac contusion are: Bruising, swelling, crepitus or deformity to chest wall Tachycardia Irregular heart rhythm UNIVERSITY OF NEW MEXICO

Cardiac Contusion Treatment: Oxygenation Assisted ventilation as necessary IV therapy EKG monitoring Treatment of arrhythmias as necessary Transport to nearest appropriate trauma facility UNIVERSITY OF NEW MEXICO

Commotio Cordis: Commotio cordis, or “concussion” of the heart, is generally described as “instantaneous cardiac arrest produced by non- penetrating chest blows in the absence of heart disease or identifiable morphologic injury to the chest wall or heart.” Commotio Cordis represents one of the most common mechanisms of sudden death in sports seen in young athletes. UNIVERSITY OF NEW MEXICO

Commotio Cordis— Review of Condition Classic presentation is a blow to the chest during a sporting activity that precipitates sudden collapse, followed by death if prompt resuscitation is not available. Most commonly occurs during baseball, but can occur during hockey, lacrosse, karate, and recreational activities such as sledding or biking. UNIVERSITY OF NEW MEXICO

Case Study You are called to a baseball game for a child hit with a baseball that is now unresponsive. Bystanders initiated CPR. UNIVERSITY OF NEW MEXICO

CPR is initiated and the Cardiac monitor is applied. Initial rhythm is: 1.What rhythm do you see? 2.What is your treatment priority? Case Study UNIVERSITY OF NEW MEXICO

Case Study After delivering 3 shocks, the patient remains unresponsive, pulseless, and apneic with the rhythm shown below. What is your next intervention? UNIVERSITY OF NEW MEXICO

Case Study UNIVERSITY OF NEW MEXICO The patient has been intubated with a 6.0 ETT, and is being ventilated with high FiO2 via BVM. An IV of NS is initiated. — What is your next intervention?

Case Study Epinephrine 1:10,000 is determined to be the next intervention. Continuation of CPR and PALS/SMO protocol UNIVERSITY OF NEW MEXICO

Case Study UNIVERSITY OF NEW MEXICO Journal of the American Medical Association, 2002;287:1142-1146 In a study of 128 confirmed cases of commotio cordis, a 15% survival rate was reported when resuscitative measures were initiated within 3 minutes of the event. In cases where resuscitation was delayed, >3 minutes, the survival rate was noted to be <1%.

Pediatric Abdominal Trauma Third leading cause of pediatric traumatic death Blunt causes in 85%, penetrating trauma in 15% Blunt trauma related to MVC’s causes more than 50% of abdominal injuries in children Boogie board related injury..! UNIVERSITY OF NEW MEXICO

Anatomic Considerations Proportionally larger solid organs Less subcutaneous fat Less protective abdominal musculature Relatively larger kidneys that predispose them to renal injury UNIVERSITY OF NEW MEXICO

Anatomic Considerations Splenic injuries are the largest proportion of pediatric abdominal trauma Liver is second most injured solid organ Lap Belt Injury Sudden increase in bowel intraluminal pressure can result in intestinal perforation Chance fracture of the lumbar spine UNIVERSITY OF NEW MEXICO

Anatomic Considerations The compliant chest wall, poor thoracic musculature and weak diaphragm can lead to considerable respiratory difficulty with gastric distention UNIVERSITY OF NEW MEXICO

Epinephrine UNIVERSITY OF NEW MEXICO Generic Name: Epinephrine Trade Name: Adrenalin® Therapeutic Class: Sympathomimetic Mechanism of Action: —Alpha: Bronchial, cutaneous, renal & visceral arterial constriction. —Beta 1: Positive inotropic & chronotropic actions, increase in cardiac automaticity. —Beta 2: Bronchial smooth muscle relaxation and dilation of skeletal vasculature, blockage of histamine release.

Epinephrine Pharmacokinetics: Onset with IV injection is immediate and intensified. SC or IM injection gives a rapid onset with longer duration. Half-life is 1-4 minutes. Prehospital Indications: Cardiac arrest Bradycardia with profound hypotension Severe bronchospasm Anaphylaxis Contraindications: Hypertension Narrow angle glaucoma Pulmonary edema UNIVERSITY OF NEW MEXICO

Goal of Multicasualty Triage “To do the best for the most using the least.”

Primary Disaster Triage Goal: to sort patients based on probable needs for immediate care. Also to recognize futility. Assumptions: Medical needs outstrip immediately available resources Additional resources will become available with time

Primary Disaster Triage Triage based on physiology How well the patient is able to utilize their own resources to deal with their injuries Which conditions will benefit the most from the expenditure of limited resources

The physiology of adults and children are not the same.

Why do we need a pediatric tool? To optimize triage effectiveness to the benefit of all victims, not just children.

Why do we need an objective pediatric tool? The pediatric knowledge base and confidence levels of many EMS providers are not as good as they can and should be. Photo by Bryan Patrick, The Sacramento Bee, 2000

Pediatric multicasualty triage may be affected by the emotional state of triage officers.

START Triage RESPIRATIONS NO YES Dead or Expectant Immediate Position Airway NO YES Over 30/min Immediate Under 30/min PERFUSION Cap refill > 2 sec Control Bleeding Immediate Cap refill < 2 sec. MENTAL STATUS Failure to follow simple commands Can follow simple commands ImmediateDelayed Ambulatory = Green

START: Potential Problems with Children An apneic child is more likely to have a primary respiratory problem than an adult. Perfusion may be maintained for a short time and the child may be salvageable. RR +/- 30 may either over-triage or under-triage a child, depending on age.

START: Potential Problems with Children Capillary refill may not adequately reflect peripheral hemodynamic status in a cool environment. Obeying commands may not be an appropriate gauge of mental status for younger children.

JumpSTART Goals Modify an existing tool for use with children Utilize decision points that are flexible enough to serve children of all ages and reflective of the unique points of pediatric physiology Minimize over- and under-triage Accomplish triage within 30 second/pt goal

The JumpSTART Field Pediatric Multicasualty Triage System © (Patients aged 1- 8 years) Black = Deceased/expectant Red = Immediate Yellow = Delayed Green = Minor/Ambulatory Identify and direct all ambulatory patients to designated Green area for secondary triage and treatment. Begin assessment of nonambulatory patients as you come to them. Proceed as below: Spontaneous respirations? NO Open airway Spontaneous respirations? YES IMMEDIATE NO DECEASED YES Peripheral pulse? YES Perform 15 sec. Mouth to Mask Ventilations Spontaneous respirations?

JumpSTART: Age Initially ages 1-8 years chosen Less than one year of age is less likely to be ambulatory. The pertinent pediatric physiology (specifically, the airway) approaches that of adults by approximately eight years of age.

I’m 10!

JumpSTART: Age Current recommendation: If a victim appears to be a child, use JumpSTART. If a victim appears to be a young adult, use START.

JumpSTART: Ambulatory Identify and direct all ambulatory patients to designated Green area for secondary triage and treatment. Begin assessment of nonambulatory patients as you come to them.

Modification for nonambulatory children All children carried to the GREEN area by other ambulatory victims must be the first assessed by medical personnel in that area.

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 and move on.

The “Jumpstart” Part  If no breathing after airway opening, check for peripheral pulse. If no pulse, tag patient deceased/nonsalvageable and move on.  If there is a peripheral pulse, give 5 mouth to barrier ventilations. If apnea persists, tag patient deceased/nonsalvageable and move on. If breathing resumes after the “jumpstart”, tag patient immediate and move on.

JumpSTART: Respiratory Rate If respiratory rate is 15-45/min, proceed to assess perfusion. If respiratory rate is 45/min or irregular, tag patient as immediate and move on.

JumpSTART:Perfusion If peripheral pulse is palpable, proceed to assess mental status. If no peripheral pulse is present (in the least injured limb), tag patient immediate and move on.

JumpSTART: Mental Status Use AVPU scale to assess mental status. 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 and move on.

Modification for nonambulatory children Infants who normally can’t walk yet Children with developmental delay Children with acute injuries preventing them from walking before the incident Children with chronic disabilities

Modification for nonambulatory children Evaluate using the JS algorithm If any RED criteria, tag as RED. If pt satisfies YELLOW criteria: YELLOW if significant external signs of injury are found (ie. deep penetrating wounds, severe bleeding, severe burns, amputations, distended tender abdomen) GREEN if no significant external injury

Individuals with special health care needs may also be MCI victims!

Note for Black Category Victims Unless clearly suffering from injuries incompatible with life, victims tagged in the BLACK category should be reassessed once critical interventions have been completed for RED and YELLOW patients.
