685 Dobutamine Improves Microcirculation in a Model of Controlled Cardiac Output

Microcirculatory response during on-pump versus off-pump coronary artery bypass graft surgery

“…Preoperative measurements show similar results to those presented by Drullinsky et al, demonstrating that anesthesia induction significantly improved microcirculatory parameters during CABG. 33,34 At the onset of surgery, there is a dichotomy between the microcirculatory fluctuations of both groups. In fact, the quality of the microcirculation of ONCABG patients decreases and improves for OPCABG patients.…”

“…24 The authors use post-induction measurements as baseline although anesthesia induction has been demonstrated to improve sublingual microcirculation. 33,34 This should be accounted for when post-induction measurements are used as baseline. They also evaluate postoperative microcirculation up to one hour in the ICU.…”
