    Blood loss in AVR

    The amount of loss can vary with the procedure specifics and the personnel involved. In a hospital with a Blood Management Program, typical blood loss for a straight up Aortic Valve Replacement without other complications is between 200 - 400 ml to the autotransfusion system and another 200 - 400 to the drapes and waste sucker system. I would advise intraoperative Acute Normovolemic Hemodilution, strict monitoring of all hemodilution and return of all blood back to the patient from the bypass system and autotransfusion systems. Consider the use of a small volume autotransfusion system as well because you don't often get enough blood to warrant the use of the larger bowl and would have to discard the smaller amounts collected because of insufficient volume to process. Blood loss and dilution become greater if the procedure is complicated by other factors such as reoperation, involvement of the aorta and great vessels, endocarditis, unknown congenital anomalies or a multitude of other factors.
