Comparing anesthesia effects on heart stability during aortic valve surgery

Comparison of Hemodynamic Stability During Anesthesia Using Remimazolam and Sevoflurane in Patients Undergoing Minimally Invasive Aortic Valve Replacement Surgery : A Prospective Randomized Controlled Study

Not applicable Interventional Pusan National University Yangsan Hospital · NCT05864625

This study is testing whether a newer anesthetic called remimazolam works better than the traditional sevoflurane to keep patients with severe aortic valve stenosis stable during minimally invasive heart surgery.

What this trial studies

This study compares the hemodynamic stability of two anesthetic agents, remimazolam and sevoflurane, in patients with severe aortic valve stenosis undergoing minimally invasive aortic valve replacement surgery. It aims to assess how these agents affect intraoperative hemodynamics, particularly in preventing hypotension, which can be dangerous for these patients. Remimazolam is a newer anesthetic known for its rapid action and stability, and this study seeks to provide definitive data on its effectiveness compared to traditional sevoflurane anesthesia.

Who should consider this trial

Good fit: Ideal candidates are patients over 19 years old with severe aortic stenosis scheduled for minimally invasive aortic valve replacement surgery.

Not a fit: Patients with known allergies to benzodiazepines or propofol, those with certain comorbidities, or those requiring emergency operations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer anesthesia practices for patients with severe aortic stenosis, reducing the risk of hypotension during surgery.

How similar studies have performed: Previous studies have shown that remimazolam can be safely used in cardiac anesthesia, but this specific comparison with sevoflurane is novel.
