  1. n = 40 in Group 1, and n = 40 in Group 2.
  2. Data are expressed as median (25% to 75% interquartile). aP < 0.05, before versus after intervention; bP < 0.05, Group 2 versus Group 1.
  3. MAP, mean arterial pressure; CItd, cardiac index measured by thermodilution; CIpc, pulse contour-based cardiac index measured with the PiCCO device; CIpw, arterial-pressure waveform-based cardiac index measured with the Vigileo device; SVRi, systemic vascular resistance indexed for body surface; GEDVi, global end-diastolic volume indexed for body surface.
