Left Urine Displacement in Maternal Cardiac Arrest

The Society of Setric Anesthesia and the AHA published a consensus statement. And they recommend during maternal cardiac arrest that there's an actual left urine displacement either by somebody pushing it away or someone physically pulling it towards them. Two MRI study that also looked at IVC volume found that a 15 degrees of tilt IVC volume didn't change at all. You need almost 30 degrees to even get some increase in IVC volume, which you can imagine is sometimes not clinically feasible to tilt someone,. especially our obese patients 30 degrees.
