About this trial
The goal of this randomized clinical trial is to compare different types of advanced hemodynamic monitoring in patients undergoing major abdominal surgery.
Participants undergoing major abdominal surgery will receive anesthesia with two different types of hemodynamic monitoring - group A will receive arterial pressure cardiac output algorithm with the FloTrac sensor and group B will receive hemodynamic monitoring with the Hypotension Prediction Index.
The main question the study aims to answer is:
• will the hypotension prediction index algorithm reduce the rate of hypotension in comparison to arterial pressure cardiac output algorithm.
