Lung Ultrasound-guided Hemodynamic Optimization

In the control group, the haemodynamic management of the patients is done according to usual practice by maintaining blood pressure with noradrenaline and optimising stroke volume with vascular filling.

In the interventional group, intraoperative haemodynamic management is based on an algorithm that includes measurement of the number of B-lines appearing on pulmonary ultrasound after vascular filling. Monitoring of the stroke volume will also be performed in this group in order to stop the vascular filling if the ESV does not increase by more than 10%.
