The Problem….

� “Trauma is the leading cause of morbidity and mortality in the US pediatric population”

� 20,000 die each year

◦ For every death - 40 hosp, and 1120 treated in ER

� 50,000/yr acquire permanent disabilities

�Most secondary to blunt mech

� Should not be treated as “little adults”◦ Anxiety, unfamiliar individuals and surroundings

� Respond differently

� Less body fat, smaller body mass, more elastic connective tissue

� Close approximation of internal organs combined with a very pliable skeletal structure

� Children are resilient, however…

◦ The period of “meta stability”decreases with age

◦ Some describe the “platinum half-hour”

� Case in point…

◦ If presenting with hypotension, 30% of blood volume has been lost
