Abstract: One hundred and twenty-five ICU patients with shock in the recent 10 years were analyzed retrospectively. According to the classification proposed by Weil et al, the shock was classified as hypovolemic shock, distributive shock, cardiogenic shock and obstructive shock. It was found that more than half of the total cases were hypovolemic shock. The mortality of hypovolemic shock was significantly lower than other types of shock. No significant differences were found in age, admission APACHEⅡ score and duration of ICU stay among the 4 types of shock. Septic shock is a subtype of distribution shock. Its morbidity of MODS and mortality was significantly higher than that of the hypovolemic shock.

Key words: hypovolemic shock, septic shock, MODS, mortality
