Outcomes
Patients underwent standardized balanced general anesthesia and invasive monitoring, to obtain the hemodynamic variables measured through a central venous catheter which was recorded by the FloTrac / Vigileo System ™ (Monitor Edwards Life sciences ) in real-time. The gasometric parameters utilize an arterial line to measure lactate, serum electrolytes, and mean arterial pressure (MAP). Fentanyl consumption was noted in both groups. Hemodynamic constants, such as heart rate (bpm), respiratory rate (FR), temperature (°C), blood pressure (BP), mean arterial pressure (MAP), peripheral oxygen saturation (SPO2%), Cardiac output (CO), venous oxygen saturation (SVO2%), systemic vascular resistance (SVR) and central venous pressure (CVP) were obtained on a Datex-Ohmeda monitor .
