I've seen situations where a patient has had surgery, received some fluid during the procedure, discharged home, and readmitted upto a week later, with a diagnosis of too much fluid during anesthesia when there are clearly other issues in play. A week later! I've seen surgeons blame anesthesia for kidney failure in a patient who had a liver transplant, when that is clearly a known complication during such an extensive operation. Seems to me that in particular surgeons are micro managers... at least in general... at least at the University level. I've had surgeons ask me to give blood products to patients at the same time not to raise the central venous pressure (which is a measure of volume status and raised directly by giving fluids or blood)
I'm not saying anesthesiologists are perfect. I'm saying that we've been to medical school too, and we've gone through specialized training. Give us a break.
