Summary

Digestive tract is supposed to be the motor of multiple organ failure. In ICU patients, mesenteric ischemia appears even when macrocirculatory parameters are controlled especially in our experience in patients coming in ICU after a cardiac surgery. The investigators suppose that microcirculatory failure develops and results in suffering of non major organs like muscle, skin and digestive tracts. In this study the investigators monitor digestive tract with plasmatic IFABP dosage and microcirculatory circulation with NIRS during a VOT and plasma glycocalyx measurements. The population is composed by patients having coronary artery bypass during cardiopulmonary bypass.

The first aim of this study is to show that digestive tract is suffering with the use of extracorporeal circulation and will be assessed with Plasmatic Intestinal Fatty Acid Binding Protein when IFABP will more than 300 pg/ml ; and with citrullinemia when citrullinemia will be less than 20 micromol/L.

The second aim is to investigate link between endothelial dysfunction and digestive tract. Endothelial dysfunction is assessed with tissular oxygen saturation before, during and after a vascular occlusion test of 3 minutes (measurement of basal value, desaturation curve, resaturation curve and hyperemic response by measurement of area under curve). Endothelial glycocalyx and NO pathway will be investigate (see under)

Our objective is to enroll 100 patients. The same study will be done in a group of patients who benefit from coronary artery bypass without extracorporeal circulation to see the effects of extracorporeal circulation support.
