Personalized Hemodynamic Management in High-risk Major Abdominal Surgery

Personalized hemodynamic management: Intraoperative cardiac index will be maintained at least at the preoperative baseline cardiac index. Preoperative baseline cardiac index will be determined one day before surgery with the patient being awake and resting in the supine position using the Starling Fluid Management System (Baxter, Deerfield, IL, USA) Preoperative baseline cardiac index will be determined with the patient being awake and resting in supine position using the Starling Fluid Management System (Baxter, Deerfield, IL, USA) (usually at least one day before surgery). We will define the individual preoperative baseline cardiac index as the average value over a 5 min period at rest (minimum cardiac index threshold: 2.2 L min-1 m-2). Intraoperative cardiac index will be measured using the Baxter Starling Fluid Management System.
