Today's children are rambunctious, playful, and aggressive and are provided through the miracles of modern technology with ample opportunities to injure themselves. As such, they are a source of both joy and terror to their parents. It is a "given" that many of them will injure themselves in the course of growing up. When they come to us in the ED waiting room, they are typically very frightened and usually in pain. We are fortunate that we have techniques and drugs to alleviate this pain and to attenuate their fear. It is our responsibility as anesthesiologists to ensure that these drugs and techniques are used appropriately and cause no further harm. We hope the information contained in this chapter may be of benefit in achieving this goal.
