The clinical features of 76 multiple-trauma patients in the intensive care unit were observed with acute physiology and chronic health evaluation (APACHE II) system. The results showed that the mean value of APACHE II scores in 76 patients was 18.4; the mean duration of staying at the ICU was 91.5 hours. Six patients died in the ICU (7.9%), 13 patients were complicated with MODS (17.1%), and 10 patients developed ARDS (13.2%). As APAHCE II scores increased, the duration of the patient staying at the ICU lengthened and the mortality went up.
