When you think of trauma in children, think of Charlie Brown. Large head, no neck, his chest and abdomen form an underdeveloped, amorphous shape.
Alternatively, think of children as apples – they are rounder than they are tall, with a large increased surface area. Apples don’t have a hard shell or thick rind to protect them. If you drop them, you may not see any evidence of damage to the outside, but there can be considerable bruising just under the surface.
A 5-year-old boy who was playing with his older brother in front of their home when the ball rolled into the street. He ran after it, and was struck by a sedan going approximately 30 mph.
This is the so-called Wadell’s triad that occurs in a collision of auto versus pedestrian or auto versus bicycle. The initial impact is the greatest, and will vary depending on the child’s height and what part of his body reaches up to the bumper of the car. Depending on the height of the child and the height of the car, the initial impact will cause a femur fracture, a pelvic fracture, or direct abdominal trauma. The second impact happens as the child is flung onto the grill or the hood of the car, causing usually thoracic trauma. The third impact can be the coup de grace – to add insult to major injury, the child is then propelled forward, worsening the two previous impacts’ injuries and adding a third – severe blunt head trauma.
If your patient has any subtle change in mental status, intubate early. In pediatric trauma, we need to be proactive. Hypoxia is our enemy.
Thankfully cervical spine injuries in children are uncommon, and when they do occur, they typically occur at the child’s fulcrum, which is at C2. Compare this with an adult’s injury pattern with our fulcrum at C7. Be careful and minimize manipulation of the cervical spine, but do what you must to visualize the chords and place the tube. Keep the neck midline, and realize that the child’s usual decrease respiratory reserve is even more affected by trauma. Preoxygenate and pass that tube quickly.
Chest tube sizing in pediatrics is straightforward if we remember that the traditional chest tube size is 4 x the ETT size.
Try using a pigtail catheter.
It’s roughly where you would put on a generous dose of deodorant. Insertion here minimizes the risk of damage to nerves, vessels and organs.
In a 40-year review of ED thoracotomy, Moore et al. analyzed 1,691 patients who received ED thoracotomy. Overall all-cause adult survival was 6.1%. In children ? 15 years of age, overall all-cause survival was considerably less, at 3.4%.
In a large case series and review of the literature for pediatric ED thoracotomy, Allen et al. found a survival rate in penetrating trauma of 10.2%, with a much lower survival rate in blunt pediatric arrest, at 1.6%. Adolescents had more penetrating injuries, and younger children had more blunt trauma.
To synthesize, the rarity of ED thoracotomy in children is due to the fact that:
If you have access to resuscitative endovascular balloon occlusion of the aorta or REBOA, this may be an option to temporize the child to get him to the relative control of the operating room. REBOA involves accessing the common femoral artery, passing a vascular sheath, floating a balloon catheter to the appropriate section of the aorta, and inflating the balloon to occlude blood flow.
Brenner et al. described a case series of 6 patients from two Level I trauma centers. They used REBOA for refractory hemorrhagic shock due to either blunt or penetrating injury. After balloon occlusion, blood pressure improved sufficiently to take the patient either to interventional radiology or to the OR. Four patients lived, two died. The AORTA trial is underway to investigate its use in trauma.

This post and podcast are dedicated to Dr Al Sacchetti, MD, FACEP. Thank you for promoting the emergency care of children and for spreading the message that you don’t need subspecialty training to take good care of acutely ill and injured children.
