Figure 2 Example of study drug titration based on the hemodynamic status. Inotropes (eg, dobutamine), vasoconstrictors (eg, norepinephrine), or epinephrine (that is both an inotrope and a vasoconstrictor) can be used before and after randomization. Volemia optimization occurs at any moment (before and after randomization) in cardiac surgery patients with complicated postoperative course. The suggestion to increase the study drug dose in patients with CI > 2.5 L/(min m2) and MAP >70 mm Hg has the aim to reduce the dose of standard inotropes or vasoconstrictors. MAP, mean arterial pressure; CI, cardiac index. American Heart Journal , 66-73DOI: ( /j.ahj ) Copyright © 2016 Elsevier Inc. Terms and Conditions
