Investigating Dexamethasone and Olanzapine in Heart Surgery

Official title: Dexamethasone, Olanzapine, Flow-targeted Versus Pressure-targeted Hemodynamic Management, and Low Tidal Volume Ventilation in Patients Undergoing On-pump Cardiac Surgery - a Multifactorial Design Randomized Trial

Run by Copenhagen University Hospital, Rigshospitalet · NCT05635227 · Data updated 2026-11-12

This study is testing different treatments and strategies during heart surgery to see if they can help patients recover faster and spend more days at home after the operation.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults scheduled for elective CABG and/or AVR.

Probably not a fit

Patients requiring acute surgery, those with active infections, or those with severe comorbidities may not benefit from this study.

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

What this trial studies

This clinical trial evaluates the effects of four different interventions on patients undergoing open heart surgery, specifically coronary artery bypass grafting (CABG) and aortic valve replacement (AVR). The interventions include administering dexamethasone or a placebo after anesthesia induction, olanzapine or a placebo before anesthesia, a blood-flow targeted versus a blood-pressure targeted hemodynamic strategy during cardiopulmonary bypass, and low-tidal volume ventilation versus no ventilation during the procedure. The primary endpoint is the number of days alive and outside the hospital within 90 days post-surgery. The study aims to reduce the risk of mortality and morbidity associated with these surgical procedures.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery outcomes and reduced hospital stays for patients undergoing heart surgery.

How similar studies have gone: Other studies have explored similar interventions in cardiac surgery, but this specific combination of treatments is novel.
