Intensivist and passionate slayer of venous congestion Philippe Rola (@thinkingcc) shows us how to deresuscitate the septic patient, with guidance from his handy ultrasound.
- Fluid overload is harmful and should be actively reduced, even in a patient in active shock; it will not harm them.
- The VEXUS exam is a good method for stratifying fluid overload by severity, i.e. severe (and harmful) versus mild (and relatively benign).
- The IVC, CVP, or hepatic vein doppler offer similar information, and are all effective means of assessing central venous pressure, the first and most important step in evaluating for venous congestion. The portal vein doppler offers the most additional diagnostic yield on top of this. Renal vascular doppler acts mostly as a “tiebreaker” when these other studies are equivocal.
- No one study or datapoint tells the whole story in these patients. Gather data from as many sources as possible to form the clearest picture.
