DrugFor goal directed volume management we use corrected aortic flow time (FTc) and stroke volume derived from esophageal Doppler as in previous studies. In case of hypovolemia, detected by esophageal Doppler monitoring (CardioQ, Deltex Medical Group PLC, Chichester, UK) according to a previously published algorithm, an additional fluid bolus of 250 ml of LR will be given over a period of 5 minutes.
