Pediatric medical traumatic stress refers to a set of psychological and physiological responses of children and their families to pain, injury, serious illness, medical procedures, and invasive or frightening treatment experiences. These responses may include symptoms of arousal, re-experiencing, and / or avoidance. They may vary in intensity, are related to the subjective experience of the event, and can become disruptive to functioning.
