What this trial studies

This multicenter interventional study aims to evaluate the feasibility of using advanced monitoring technologies, including Acumen HPI Smart Alerts and the HemoSphere platform, in patients undergoing moderate to high-risk noncardiac surgery. The study will compare outcomes with historical controls to assess the effectiveness of these monitoring tools in improving patient management during surgery. Eligible participants will be adults undergoing elective noncardiac surgeries lasting at least three hours, with specific monitoring requirements. The study focuses on enhancing intra-operative hemodynamic management to potentially improve post-operative outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older scheduled for elective noncardiac surgery lasting three hours or more, with specific monitoring needs.

Not a fit: Patients who are undergoing emergency surgeries, intracranial or cardiac surgeries, or those with severe renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of patients during noncardiac surgeries, potentially reducing complications and enhancing recovery.

How similar studies have performed: While this approach is innovative, similar studies utilizing advanced monitoring technologies have shown promise in improving surgical outcomes.
