Prospective study reveals increased pump flow improves diuresis in cardiac surgery patients, suggesting maintaining higher perfusion pressure supports kidney function.
Key Points
Elevated pump flow during cardiopulmonary bypass increased intraoperative diuresis and reduced renin release, but systemic acute kidney injury rates were unchanged.
Prospective single-centre study of 109 adults targeted a mean arterial pressure above 90 mmHg, comparing outcomes against standard pump flow protocols.
Highlights that optimizing pump flow reduces renal hypoperfusion without neurological risk, although single-center findings warrant broader clinical validation.
