To Investigate the Effect of Esketamine on Hemodynamics and Postoperative Pulmonary Complications in Patients Undergoing Heart Valve Replacement Surgery

Phase 4 Interventional Zunyi Medical College · NCT06467513

This study is testing if giving esketamine during heart valve replacement surgery can help prevent breathing problems after the surgery for patients aged 18 to 75.

What this trial studies

This study evaluates the impact of esketamine hydrochloride on intraoperative hemodynamics and postoperative pulmonary complications in patients undergoing heart valve replacement surgery. Eligible participants, aged 18-75, will be randomly assigned to receive either a low or high dose of esketamine or a control solution during surgery. The study employs a double-blind methodology to ensure unbiased results. The primary goal is to determine if esketamine can improve outcomes related to pulmonary complications following heart surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 scheduled for elective mitral or aortic valve replacement surgery requiring extracorporeal circulation.

Not a fit: Patients with existing pulmonary complications or those undergoing non-cardiac surgeries will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative recovery and reduced pulmonary complications for patients undergoing heart valve surgery.

How similar studies have performed: While the use of esketamine in this context is relatively novel, similar studies have shown promising results in managing intraoperative hemodynamics.
