Damage Control Philosophy in Polytrauma.

Severe traumatic injury is a public health care problem; with injuries accounting for 12% of the global mortality. Continued improvement in the survival of severely injured trauma patients is a paramount goal. Bailout/damage control surgery following trauma has developed as a major advance in surgical practice in the last twenty years. The principles of damage control surgery defied the traditional surgical teaching of definitive operative intervention and were slow to be adopted. Currently, damage control surgery has been successfully utilized to manage traumatic thoracic, abdominal, extremity, and peripheral vascular injuries. In addition, damage control surgery has been extrapolated for use in general, vascular, cardiac, urologic, and orthopaedic surgery. Stone et al were the first to describe the "bailout" approach of staged surgical procedures for severely injured patients. This approach emerged after their observation that early death following trauma was associated with severe metabolic and physiologic derangements following severe exsanguinating injuries. Profound shock along with major blood loss initiates the cycle of hypothermia, acidosis, and coagulopathy. During the 1980s, hypothermia, acidosis, and coagulopathy were described as the "trauma triangle of death" which makes the prolonged and definitive operative management of trauma patients dangerous. The management technique, now described as "damage control" by Rotondo et al, involves a multiphase approach, in which reoperation occurs after correction of physiologic abnormalities.
