Brief Summary
The investigators hypothesize that dobutamine is able to revert negative redistribution of flow by inducing a selective vasodilatory effect on hypoperfused territories, particularly at the sublingual and gastric mucosa, and at the peripheral tissues. The investigators designed a randomized, cross-over, placebo-controlled study looking at the acute physiologic effects of 5 mcg/kg/min fixed-dose of dobutamine on cardiac function, microcirculation, gastric mucosal, hepatosplanchnic, and peripheral perfusion in septic shock patients.

Outcome Measures
Primary Outcomes (1)
Change in the perfused vascular density
Perfused vessel density is a measure of sublingual microcirculation. It will be assessed with SDF videomicroscopy (Microscan ® for NTSC, Microvision Medical, Amsterdam, NL). (Crit Care 2007; 11:R101).

Study Arms (2)
Dobutamine
ACTIVE COMPARATORDobutamine at 5 mcg/kg/min will be administered for 2.5 hours
Placebo
PLACEBO COMPARATORAn equivalent infusion of placebo will be infused for 2.5 h
Interventions
Dobutamine at 5 mcg/kg/min will be administered for 2.5 hours each. Measurements will be performed at baseline (within 30 minutes before starting the infusion) and repeated within the last 30 minutes of drug infusion.
A 5% dextrose solution will be administered for 2.5 hours. Measurements will be performed at baseline (within 30 minutes before starting the infusion) and repeated within the last 30 minutes of drug infusion.
