  1. Median (range) or number (percentage), where appropriate; CV SOFA = cardiovascular sequential organ failure assessment score, preop. = preoperatively, max = maximum, min = minimum, HR = heart rate, MAP = mean arterial pressure, CI = cardiac index, PAOP = pulmonary artery occlusion pressure, CVP = central venous pressure, SvO2 = mixed or central venous O2 saturation, nor = norepinephrine, dop = dopamine, na = not applicable. The change in minimum CI (P = 0.024) and fluid balance from 24 h prior to and after rethoracotomy (P = 0.004) differed between groups.
