Why the study?

Intraoperative hypotension is common during major surgery and linked to adverse outcomes, making proactive prediction and prevention through machine-learning algorithms a potential strategy to improve patient care.

Implication

IOH below MAP 65 mmHg signals heightened perioperative risk; leaves optimal thresholds and interventions open for prospective trials.

Structured PICO

P
Population
Patients undergoing major surgical procedures under general anaesthesia
I
Intervention
Machine-learning algorithms (e.g., hypotension prediction index [HPI]) for predicting and preventing intraoperative hypotension
O
Outcome
Prediction of intraoperative hypotension

Machine-learning algorithms like the hypotension prediction index offer a novel approach to predict and potentially prevent intraoperative hypotension, which is associated with adverse perioperative outcomes.
