In 3 months, 58 patients were included. The average age was 46.6 years, and 36 were male. Overall mortality was 14%. We included 16 patients with sepsis syndrome, 27 patients with severe sepsis and 15 patients with septic shock. Severe sepsis patients presented with higher values of CI, when compared with sepsis syndrome and septic shock patients (3.46, 3.08 and 2.92 l/minute/m2, respectively, P = NS). The same occurred with VTI (19.27, 18.81 and 16.74 cm for severe sepsis, sepsis syndrome and septic shock, respectively; P = NS). Mean values of CI were lower in nonsurvivors of sepsis (2.51 vs. 3.35 L/minute/m2, P = 0.018). Mean values of VTI were also lower in nonsurvivors (14.83 vs. 19.01 cm, P = 0.022).
