What this trial studies

This study evaluates the effects of inhaled nitric oxide on pulmonary vasculature and right ventricular function in patients recovering from cardiac surgery. It aims to assess the combination of inhaled nitric oxide with an alveolar recruitment strategy to enhance gas exchange and improve heart performance. The study will involve a randomized controlled design, focusing on physiological variables to understand the mechanisms at play. A total of 54 patients will be recruited for this prospective study, which will take place in two hospitals during the first few hours post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are mechanically ventilated and have postoperative lung collapse.

Not a fit: Patients with severe hypovolemia or unstable hemodynamics may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery outcomes for patients undergoing cardiac surgery by enhancing lung function and heart performance.

How similar studies have performed: Other studies have shown promising results with inhaled nitric oxide in similar contexts, suggesting potential for success in this approach.
