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.

Trial outcomes

Primary outcomes

1

Time weighed average of hypotension below 65 mmHg

depth of hypotension in millimetres of mercury below a mean arterial pressure (MAP) of 65 mmHg x time in minutes spent below MAP of 65mmHg)/total duration of operation in minutes

Time frame
"From the beginning of the anesthesia to the end of anesthesia (from induction - start of anesthesia to end of anesthesia - discharge from the post anesthesia department), assessed up to 30 days

Secondary outcomes

1

Time weighed average of hypotension below 50 mmHg

depth of hypotension in millimetres of mercury below a MAP of 50 mmHg x time in minutes spent below MAP of 50 mmHg)/total duration of operation in minutes

Time frame
"From the beginning of the anesthesia to the end of anesthesia (from induction - start of anesthesia to end of anesthesia - discharge from the post anesthesia department), assessed up to 30 days
2

Time weighed average of hypertension above 90 mmHg

rise of hypertension in millimetres of mercury above a MAP of 90 mmHg x time in minutes spent above MAP of 90 mmHg)/total duration of operation in minutes

Time frame
"From the beginning of the anesthesia to the end of anesthesia (from induction - start of anesthesia to end of anesthesia - discharge from the post anesthesia department), assessed up to 30 days
3

Time weighed average of hypertension above 100 mmHg

rise of hypertension in millimetres of mercury above MAP of 100 mmHg x time in minutes spent above MAP of 100 mmHg)/total duration of operation in minutes

Time frame
