Given that the CVP emperor now provably has no clothes, and there are a multitude of devices measuring continuous cardiac output and various other parameters that might be used to guide intra-operative fluid management — and let's not forget the trans-esophogeal echo — has there been any demonstrable benefit of one modality over another?
I am particularly interested in how these compare to the readily measured systolic pressure variation and pulse pressure variation, which are becoming an increasingly common (and easy!) way of guiding intraoperative fluid management.
Any comparative evidence, especially evidence focusing on outcome data?
