This episode explores the critical role of **lactate metabolism** as a biomarker for assessing organ quality in **Donation after Circulatory Death (DCD)** compared to **Donation after Brain Death (DBD)**. While the heart typically consumes lactate and the liver clears it, the **warm ischemia** inherent in DCD causes a shift toward anaerobic metabolism and significant lactate accumulation. To mitigate this injury, advanced **ex vivo perfusion** and **normothermic regional perfusion** techniques are utilized to monitor **lactate clearance trends** as a primary indicator of graft viability…
