I had a Pt. last night, 84yo immediate PO redo CABG, had trouble coming off pump, on a balloon pump, epi, mil, norepi, vaso, vented, etc...anyway I was giving an albumin bolus pressure started to drop went up on the pressors and when the infusion was finished the pressure recovered. Later on I gave another albumin bolus same thing. I stopped the infusion and the pressure came back up. We then tried NS and had no drop in pressure. Anyone have any insight as to why albumin would drop blood pressure?
