Initial Postoperative Hemoglobin Values

This is referred to as "patient blood management." Lung transplantation is a complex surgical procedure that frequently necessitates intraoperative transfusion of blood products. One of the four patients undergoing lung transplantation requires a massive blood transfusion. Because pre-transfusion hemoglobin thresholds may be impractical and inaccurate during active bleeding and in thermodynamically unstable patients, they should be avoided. In the absence of high-quality data, clinicians rely heavily on the outcomes of cardiac surgery patients. Patients undergoing lung transplantation, on the other hand, differ from other surgical patients in many ways. As a result of chronic hypoxia, many of them have pre-operative polycythemia, while others are anemic due to underlying chronic infections. Furthermore, the lung is the only solid or liquid organ.
