Using a monitor to predict low blood pressure in surgical patients after surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
