Trauma patients and families have to face the sudden onset of accident, expensive medical cost, incidious complications and body image changes and so on.

Even though trauma nursing may be included in the nursing care of general surgery, orthopedic surgery, thoracic surgery, neurosurgery, genitourinary surgery, colorectal surgery and rehabilitation, it does have a unique characteristic and bright future.
