Oesophageal Doppler guided optimization of cardiac output does not increase visceral microvascular blood flow in healthy volunteers.

BACKGROUND Oesophageal Doppler monitoring (ODM) is used clinically to optimize cardiac output (CO) and guide fluid therapy. Despite limited experimental evidence, it is assumed that increasing CO increases visceral microvascular blood flow (MBF). We used contrast-enhanced ultrasound (CEUS) to assess whether ODM-guided optimization of CO altered MBF… CONTINUE READING
