The effects of infusions of dobutamine (median 60 minutes), enoximone (median 85 minutes), and norepinephrine (median 75 minutes) on parameters of macro- and microcirculation.

Abbreviations: HR, heart rate; MAP, mean arterial pressure; CVP, central venous pressure; PCWP, pulmonary capillary wedge pressure; MPAP, mean pulmonary artery pressure; CI, cardiac index; SVR, systemic vascular resistance; SvO2, mixed-venous oxygen saturation; delta-T, central-peripheral temperature gradient; PCD, perfused capillary density. Values represent median [interquartile range]. The p-value in the last column represents differences among groups. Asterisks indicate statistical significance versus baseline: *, p<0.05; **, p<0.01. P-values>0.05 (NS, non-significant) are not shown. aA pulmonary artery catheter was present in 27/33 (82%) of the measurements.
