Why the study?
Intraoperative hypotension increases morbidity and mortality, but whether the Hypotension Prediction Index with a personalized protocol reduces intraoperative hypotension compared with arterial waveform analysis alone remained to be tested.
Does Hypotension Prediction Index (HPI) guidance reduce the incidence and duration of intraoperative hypotension in adults undergoing moderate- or high-risk noncardiac surgery?
Population
100 consecutive adult patients undergoing moderate- or high-risk noncardiac surgery with invasive arterial pressure monitoring
Comparison
Hypotension Prediction Index guidance vs arterial waveform analysis (FloTrac)
Design
Retrospective analysis

HPI with personalized protocol was associated with less hypotension; leaves open prospective confirmation before adoption.
Does Hypotension Prediction Index (HPI) guidance reduce the incidence and duration of intraoperative hypotension in adults undergoing moderate- or high-risk noncardiac surgery?
The use of the Hypotension Prediction Index combined with a personalized treatment protocol significantly reduces the incidence and duration of intraoperative hypotension compared to standard arterial waveform analysis.
