Abstract： Objective To explore the value of trauma seore(TS)in emergency care according to anatomy,physiological parameters of patients in order to improve the efficiency of emergency care.Method The injury severity of 1568 patients with trauma admitted to Emergency Department was assessed with TS,and complieations were recorded in Jinshan Branch of Sixth Municipal Hospital Affiliated Shanghai Jiaotong University.The interventions,monitoring and imaging examinations started immediately after admission.Results The lower the TS,the poorer the patient's condition.However,the sensitivity of TS was low in the patients with brain injury,whereas the Glasgow coma score (GCS)was more valuable.The patients with score of 10 or above accounted for 72.39% of patients while 27.61% patients had score of 10 or below.Alout 91.52%patients who had TS above 10 and 8.41% patients who had TS 10 or below survived and were discharged from Emergency Department(both P＜0.001).The patients with score of 10 or below had a higher rate of severe complications including hypotension,shock,abnormal respiration and cardiac arrest.The lower the TS,the larger the volume of fluid resuscitation reqired.Conclusions TS is an objective valuein assessing the seriousness of the oatient's condition,which can help doctors quickly deal with the injured patients.Rapid administration of more than 1500 mL of fluid,is especially necessary for the trauma patients with hemontlagic shock in the period of"golden one hour"after injury.
