Key result
Customized cardiopulmonary bypass with goal-directed perfusion and pulsatile flow resulted in enhanced kidney function and reduced lactate levels post-surgery in a high-risk patient.
Why the study?
Multi-organ failure from cardiopulmonary bypass significantly contributes to postoperative morbidity and mortality, particularly in high-risk patients undergoing cardiac surgery.
Does pulsatile flow combined with goal-directed perfusion improve organ perfusion and clinical outcomes in a high-risk patient undergoing CABG and aortic valve replacement?

Does pulsatile flow combined with goal-directed perfusion improve organ perfusion and clinical outcomes in a high-risk patient undergoing CABG and aortic valve replacement?
The integration of pulsatile flow and goal-directed perfusion during cardiopulmonary bypass in a high-risk patient may enhance organ perfusion, leading to the recovery of renal and cardiac function.

Single case of high-risk CABG/AVR with CPB; hypothesis-generating and should not yet change practice.
The development of multi-organ failure resulting from cardiopulmonary bypass (CPB) is acknowledged as a significant contributor to increased morbidity and mortality rates during the postoperative period. This report discusses a patient who presents with multiple comorbidities, including renal failure, reduced ejection fraction, and a history of hypertension, and is being considered for coronary artery bypass grafting (CABG) along with aortic valve replacement surgery. The administration of CPB was customized to address the unique comorbid conditions of the patient, highlighting the critical objective of maintaining an oxygen delivery index (DO2i) exceeding 280 mL/min/m2, while also integrating pulsatile flow methodologies. The management of CPB, as previously discussed, resulted in a notable enhancement of kidney function, accompanied by a reduction in the patient’s lactate levels post-surgery.
