OBJECTIVE: This prospective study evaluated serum total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI), along with the Revised Trauma Score (RTS) and Injury Severity Score (ISS), as predictors of clinical outcome in the early post-traumatic period in patients with multiple blunt trauma (MBT). METHODS: The study included 52 patients admitted to the emergency department with MBT and 40 age- and sex-matched healthy control subjects. RESULTS: The overall MBT patient mortality was 32.7% (17/52). There was no significant association between age and mortality in MBT patients, but there was a negative correlation between mortality and RTS, and a positive correlation between mortality and ISS. TOS levels were significantly higher in nonsurvivors compared with survivors. There was no correlation between TAS or OSI and survival. ISS and RTS showed positive and negative correlations with TOS level, respectively, but neither was significantly related to TAS or OSI. CONCLUSIONS: These findings suggest that TOS, as an early oxidative stress biomarker, may be an objective alternative criterion to the ISS and RTS for managing patients with MBT during the early period following traumatic injury.
