Fig. 2. For the same mean arterial pressure, modification of gastric mucosal laser-Doppler perfusion (GMP) expressed as arbitrary perfusion units (PU) during baseline, after 2-h infusion of fenoldopam and placebo, and after 3 h (1 h after discontinuing fenoldopam and placebo). bP < 0.001 versus baseline; cP < 0.001 versus 3 h; dP < 0.001 versus placebo.
