My personal record is "Doc, we don't have enough cells in the sample to give an accurate Hgb." 34 yo minimally responsive, pale as a ghost, dropped off by friends who mention something about hematemesis and take off. No other hx provided. He's hypotensive, HR of 150, RR of 50. Blood looks like just serum w/ a single drop of food coloring. Abdomen is swollen. His hgb was 2.0 after 4 units of pRBCs. I kept that guy alive for 10 hours, stayed 3 hrs after my shift. Mass transfusion protocol, 20 u pRBCs, 10u Plts, 10u FFP. Blakemore tube. GI won't scope. IR won't touch the pt because he is too unstable and INR is >10. His lactic acid was 45. His pH was 6.7. I waited about 2 hrs before intubating him because I felt that intubation would be an immediate death sentence, as there was no way I could match his minute ventilation on the vent, but he eventually started looking a bit better after about 10u pRBCs, so I figured that was my time to intubate. Put him at a RR of 36 on the vent, with a tidal volume of 800 (he was a small guy), just to try to somewhat match his MV. Initial NG tube placed puts out 2L of blood from his stomach. Blakemore tube then placed, but not much improvement. ICU admitted him. Blood bank eventually ran out of blood to release. The patient died a few hours later.
