Why the study?

Intraoperative hypotension is common under general anesthesia and can cause serious complications, prompting comparison of perioperative hypotension frequency using different hemodynamic monitoring technologies.

Does the Hypotension Prediction Index (HPI) algorithm reduce perioperative hypotension in patients undergoing major abdominal surgery compared to arterial pressure-based cardiac output technology?

Overview

Should not yet change monitoring practice; leaves open whether less IH with HPI improves organ outcomes in trials.

Structured PICO

Does the Hypotension Prediction Index (HPI) algorithm reduce perioperative hypotension in patients undergoing major abdominal surgery compared to arterial pressure-based cardiac output technology?

P
Population
123 patients undergoing major abdominal surgery receiving general anesthesia
I
Intervention
Hypotension Prediction Index (HPI) algorithm hemodynamic monitoring
C
Comparator
Arterial pressure-based cardiac output (APCO) technology (FloTrac group)
O
Outcome
Time-weighted average (TWA) of hypotension below < 65 mmHgsurrogate

The Hypotension Prediction Index algorithm significantly decreases the frequency and duration of perioperative hypotension events in patients undergoing major abdominal surgery compared to arterial waveform analysis alone.
