*Inotropic score (IS) was calculated using dopamine dose (mcg/kg/min) + dobutamine dose (mcg/kg/min) + 100 × epinephrine dose (mcg/kg/min). *Vasoactive-inotropic score (VIS) was calculated using IS + 10 × milrinone dose (mcg/kg/min) + 10,000 × vasopressin dose (units/kg/min) + 100 × norepinephrine dose (mcg/kg/min). BD, base deficit; ECMO, extracorporeal membrane oxygenation; VA, venoarterial; VV, venovenous. pCO2 and pO2 in mmHg. HCO3 in meq/L.
