What complication could arise from the aggregation of leukocytes during CPB?

The aggregation of leukocytes during cardiopulmonary bypass (CPB) is closely linked to the activation of inflammatory pathways. This phenomenon occurs due to several factors associated with CPB, including contact with artificial surfaces, hypothermia, and systemic inflammatory response. As leukocytes aggregate, they can release various pro-inflammatory mediators, such as cytokines and chemokines, which further amplify the inflammatory response.

This activation of inflammatory pathways can lead to a range of complications, including organ dysfunction (such as acute kidney injury or lung injury) and prolonged recovery time post-surgery. Understanding this relationship is crucial for perfusionists and the surgical team to develop strategies to mitigate such inflammation, ultimately improving patient outcomes.

Options relating to increased production of antibodies, enhanced organ perfusion, and improved response to anesthesia do not directly connect to the aggregation of leukocytes. Instead, the aggregation predominantly perpetuates an inflammatory state, which can detrimentally affect organ function and overall patient recovery.
