MAP- Versus Cardiac Index-Guided Hemodynamic Management in Whipple Surgery
Sponsor: Ankara Etlik City Hospital
Summary
This prospective randomized study aims to compare the effects of two intraoperative hemodynamic management strategies on early postoperative renal function in patients undergoing pancreaticoduodenectomy. Patients will be allocated to either mean arterial pressure-guided hemodynamic management or cardiac index-guided hemodynamic management during surgery. Pancreaticoduodenectomy is a major abdominal surgical procedure associated with prolonged operative duration, considerable fluid shifts, blood loss, and hemodynamic instability. These factors may contribute to impaired renal perfusion and postoperative renal dysfunction. Although mean arterial pressure is commonly used to guide intraoperative hemodynamic management, blood pressure alone may not fully reflect systemic blood flow or tissue perfusion. Cardiac index-guided management may provide a more direct assessment of global circulatory adequacy. The primary outcome of the study is the change in serum creatinine level from the preoperative baseline value to the postoperative 72nd hour. Secondary outcomes include intraoperative hemodynamic variables, fluid and vasopressor requirements, urine output, postoperative renal function parameters, length of intensive care unit and hospital stay, and 30-day mortality.

Interventions
Mean Arterial Pressure-Guided Hemodynamic Management
Intraoperative hemodynamic management will be performed according to predefined mean arterial pressure targets during pancreaticoduodenectomy. Standard anesthetic care, fluid therapy, vasopressor use, and intraoperative monitoring will be applied according to institutional clinical practice.
Cardiac Index-Guided Hemodynamic Management
Intraoperative hemodynamic management will be performed according to predefined cardiac index targets during pancreaticoduodenectomy. Cardiac index values will be monitored intraoperatively, and fluid therapy, vasopressor use, and inotrope administration will be adjusted according to the hemodynamic status of the patient and institutional clinical practice.
