Most blood bankers will tell you that cardiac surgery can lead to some of the most intense interactions between a transfusion service and an operating room.

Dr. Pierre Tibi is a busy cardiac surgeon in Arizona who also happens to be a Patient Blood Management champion! Pierre joins me to pull back the curtain on what is really happening in the OR, and offers his thoughts on how we can all care best for our cardiac surgery patients (even those getting a "re-do!").
