Just had a case pt had perfed ulcer at start H&H about 13/39 next day 7 and 20 whoops. Did not transfuse intraoperativley nobody could see any blood irrigation in to amount in the suction about equel, laps were not soaked, not much blood on the drapes, I NOTHING that would indicate massive bleeding, pt a bit hypotensive 90-100 systolic with HR between 80-100 got 6000 LR intraoperativley and 500 hespan Just how MUCH can a person hemoconcentrate and then dilute, oh yeah chems were normal as were platlets, so kinda doubt hemoconcentration.
