1113 of traumatized patients treated on ICU in the Trauma hospita lin Brno were divided into the groups second the posttraumatic clinical course. Consecutively we have analysed a reasons for the development of the multiple organ dysfunction syndrome. Incidence of the traumatic shock was 34.77 % with mortality of 22.99 %. Incidence of the MODS was 12.03 %, with the mortality 58.23 %. The typical clinical find of the patients with the MODS was respiratory dysfunction (outcome in 60 %, mortality in 80 %). The difference between outcome and mortality was found with the marked incidence of cardiovascular dysfunction (60 % contrary 10 %) and acute renal dysfunction (40 % contrary 10 %). This finds confirmed very good known fact – high mortality in patient with combination of renal and respiratory dysfunction. The typical find in the patients with the MODS – outcome was incidence of the liver and the gut dysfunction. The difference between MODS – outcome and MODS mortality was in the number of existing organ dysfunction. 75 % of the patients in the group MODS – outcome had two-organ dysfunction and contrary wise in the group MODS of mortality 50 % where the patients had three-organ dysfunction and 75 % patients three-four organ dysfunctions. We found in the group of the EMODS high incidence of the trauma of the ext remities and combination of more traumatizated organs-systems. In the LMODS group the most frequent was the spinal trauma.
