Using a monitor to predict low blood pressure in surgical patients after surgery
Hypotension Prediction Index in Postoperative Surgical Patients in the Post-anesthetic Recovery Room - a Feasibility Study
This study is testing if a special monitor can help doctors predict low blood pressure in patients after they have surgery, so they can act quickly to prevent complications.

What this trial studies
This observational study evaluates the use of a hemodynamic monitor in the post-anesthetic recovery room for patients undergoing colorectal, hepatobiliary, and vascular surgeries. The goal is to determine the feasibility of recruiting this surgical population and to assess the accuracy of the hypotension prediction index (HPI) from the HemoSphere monitor and Acumen IQ sensor in predicting postoperative hypotension. By identifying patients at risk for hypotension, the study aims to facilitate early interventions that could reduce the risk of serious postoperative complications.
Who should consider this trial
Good fit: Ideal candidates are patients aged 45 and older who are scheduled for open colorectal, hepatobiliary, or vascular surgery and are expected to have an arterial cannula inserted.
Not a fit: Patients who are planned for admission to the ICU or who refuse to participate will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved monitoring and early intervention for patients at risk of postoperative hypotension, potentially reducing complications and improving outcomes.
How similar studies have performed: While the approach of using hemodynamic monitoring is established, the specific application of the hypotension prediction index in this surgical context is novel and has not been extensively tested.
