The treatment concept for severe trauma has greatly changed. In developed countries

the trauma mortality pattern has shifted from a three-peak curve to a singlet curve

resulting in a standard pattern in which multi-disciplinary surgeons take responsibility of the whole treatment course. Life-saving operations for recovering the airway

respiratory and circulatory functions also belong to resuscitation. Focus on in-hospital trauma evaluation should be distinguished in different stages following the concept of “the faster the better”. In the process of treatment

surgeons should control the pre-operation time

surgery time

and time to achieve resuscitation endpoints

with planned and staged damage control strategies by following the treatment order of ventilation

operation

bleeding control

infusion and pulsation.
