Pediatric trauma or paediatric trama refers to a traumatic injury that happens to an infant, child or adolescent.

Anatomic and physiologic differences in children

There are significant anatomical and physiological differences between children and adults. For example, the internal organs are closer in proximity to each other in children than in adults; this places children at higher risk of traumatic injury.[1]

An important part of managing trauma in children is weight estimation. A number of methods to estimate weight exist, including the Broselow tape, Leffler formula, and Theron formula.[2] Of these three methods, the Broselow tape is the most accurate for weight estimation in children ≤25 kg,[2] while the Theron formula performs better with patients weighing >40 kg.[2]

Due to basic geometry, a child's weight to surface area ratio is lower than an adult's, children more readily lose their body heat through radiation and have a higher risk of becoming hypothermic.[3][4] Smaller body size in children often makes them more prone to poly traumatic injury.[5]

Pediatric Trauma Score

Several classification systems have been developed that use some combination of subjective and objective data in an effort to quantify the severity of trauma. Examples include the Injury Severity Score[6][7] and a modified version of the Glasgow Coma Scale.[8] More complex classification systems, such as the Revised Trauma Score, APACHE II,[9] and SAPS II[10] add physiologic data to the equation in an attempt to more precisely define the severity, which can be useful in triaging casualties as well as in determining medical management and predicting prognosis.

Though useful, all of these measures have significant limitations when applied to pediatric patients. For this reason, health care providers often employ classification systems that have been modified or even specifically developed for use in the pediatric population. For example, the Pediatric Glasgow Coma Scale is a modification of the Glasgow Coma Scale that is useful in patients who have not yet developed language skills.[11]

Emphasizing the importance of body weight and airway diameter, the Pediatric Trauma Score (PTS) was developed to specifically reflect the vulnerability of children to traumatic injury. The minimal score is -6 and the maximum score is +12. There is a linear relationship between the decrease in PTS and the mortality risk (i.e. the lower the PTS, the higher the mortality risk).[11] Mortality is estimated at 9% with a PTS > 8, and at 100% with a PTS ≤ 0.

In most cases the severity of a pediatric trauma injury is determined by the pediatric trauma score[3] despite the fact that some research has shown there is no benefit between it and the revised trauma scale.[12]

Epidemiology in the United States

Pediatric trauma accounted for 59.5% of all mortality for children under 18 in 2004.[1][13] Injury is the leading cause of death in this age group in the United States—greater than all other causes combined.[14] It also is the leading cause of permanent paralysis for children.[15][16] In the US approximately 16,000,000 children go to a hospital emergency room due to some kind of injury every year.[3] Male children are more frequently injured then female children by a ratio of two to one.[3]
