Routinely intraoperatively the fluid status assessment is based on central venous pressure and other parameters. Nevertheless, the minority of anesthesiologists use continous dynamic parameters like pulse pressure variation, stroke volume variation and other to manage fluid status. There's a fast acting biomarker that can help anesthesiologist to diagnose and manage the volemic status and possibly guide the infusion therapy better.~Pro-ANP is a biomarker that reacts on atria strain and can be used in volemic status assessment in cardiac surgery patients.
Biomarkers can play a significant role in fluid status assessment intraoperatively.
