Which of the following statements about dilutional coagulopathy during CPB is true?

Dilutional coagulopathy is a significant concern during cardiopulmonary bypass (CPB) and is primarily caused by the dilution of coagulation factors due to the large volume of priming fluid used in the CPB circuit. The correct assertion is that dilutional coagulopathy occurs upon initiation of CPB and continues postoperatively.

During CPB, the patient’s blood is mixed with crystalloid and colloid solutions, leading to a dilution of clotting factors and platelets. This dilution can result in a decreased ability for blood to clot effectively, which is particularly critical during the surgical procedure when maintaining hemostasis is essential. The effects of dilutional coagulopathy do not resolve immediately after the CPB is stopped. In many cases, patients may continue to experience the consequences of this dilution, affecting their coagulation status in the postoperative period.

Consequently, monitoring and managing hemostatic function during and after CPB are crucial to mitigate the risks associated with dilutional coagulopathy, as it can lead to increased bleeding and complications post-surgery.

Other options may imply incorrect scenarios regarding the timing and effects of dilutional coagulopathy, suggesting a misunderstanding of how this condition evolves during the surgical process and its potential
