ITLS Pediatric Trauma Considerations 2

Question 1

A 4-year-old child struck by a car presents with altered mental status but stable vital signs. Why is the ITLS provider particularly concerned about intra-abdominal injury in this patient?

Accepted Answer

Children have proportionally larger solid organs, less protective subcutaneous fat, and more flexible rib cages that provide less protection, making abdominal organs more vulnerable

Answer

Pediatric anatomy makes children more susceptible to abdominal organ injury: relatively larger liver and spleen, less subcutaneous fat padding, and a more pliable rib cage that transmits rather than absorbs force.

Question 2

What is the most common cause of cardiac arrest in pediatric trauma patients, and how does this influence resuscitation priorities?

Accepted Answer

Hypoxia from airway and breathing problems, making aggressive airway management and ventilation the primary resuscitation focus

Answer

Unlike adults where hemorrhage is the primary killer, pediatric trauma cardiac arrest is most commonly caused by hypoxia secondary to airway obstruction or inadequate ventilation, making airway management the highest priority.

Question 3

How do you calculate appropriate fluid resuscitation volumes for a pediatric trauma patient?

Accepted Answer

Administer 20 mL/kg isotonic crystalloid boluses, reassessing after each bolus, with consideration for blood products after 40-60 mL/kg without improvement

Answer

Pediatric fluid resuscitation uses weight-based dosing: 20 mL/kg boluses of isotonic crystalloid (normal saline or lactated Ringer's), reassessing clinical response after each. If no improvement after 2-3 boluses (40-60 mL/kg), blood transfusion is indicated.

Question 4

Why are children at higher risk for hypothermia in the trauma setting compared to adults?

Accepted Answer

Children have a larger body surface area to mass ratio, thinner skin, less subcutaneous fat, and limited shivering capacity, causing more rapid heat loss

Answer

Children lose heat faster due to their higher body surface area to mass ratio, less insulating subcutaneous fat, thinner skin, and in infants, immature thermoregulatory mechanisms including limited shivering ability.

Question 5

What anatomical difference makes children more susceptible to cervical spine injuries at the C1-C3 level compared to the adult pattern of lower cervical injuries?

Accepted Answer

Children have proportionally larger and heavier heads, higher fulcrum of cervical motion (C1-C3 vs. C5-C6 in adults), and more horizontal facet joints that allow greater mobility

Answer

Children's disproportionately large, heavy heads create a higher fulcrum of cervical motion (C1-C3 versus C5-C6 in adults), and their more horizontal facet joints and ligamentous laxity allow greater mobility, concentrating forces at the upper cervical spine.
