Design outcomes

Primary

Measure	Time frame
To describe human gastrointestinal microcirculation on both the serosal and mucosal side of the bowel during gastrointestinal surgery under general anesthesia. Main parameter: Microvascular perfusion is quantified using the Microvascular Flow Index (MFI).	—

Secondary

Measure	Time frame
Perfused vessel density (PVD), proportion of perfused vessels (PPVs), en heterogeneity of the microcirculation. To observe the possible correlation between bowel microcirculation and systemic hemodynamic parameters. MFI, PVD, PPV and indices of heterogeneity are compared between sides and to systemic hemodynamic parameters such as blood pressure, and if accessible, cardiac output (CO), stroke volume (SV) and stroke volume variation (SVV). These latter parameters are automatically measured by the FloTrac/Vigileo and thus only accessible when an arterial catheter is inserted.	—
