Understanding lung injury in young patients after heart surgery

Neutrophil Phenotypic Profiling and Acute Lung Injury in Patients After Cardiopulmonary Bypass (CPB)

Boston Children's Hospital · NCT04296071

This study looks at how heart surgery can cause lung injury in young patients by examining the role of certain immune cells to help improve their recovery.

What this trial studies

This observational study aims to investigate the mechanisms behind acute lung injury (ALI) that can occur in pediatric patients following cardiopulmonary bypass (CPB) during cardiac surgery. It focuses on the role of neutrophils, which are immune cells that can contribute to lung damage when activated during CPB. By analyzing the behavior and characteristics of these neutrophils, the study seeks to provide insights into how CPB affects lung function and potentially leads to serious complications like acute respiratory distress syndrome. The findings could help improve postoperative care and outcomes for affected patients.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric patients under 12 months of age who are scheduled for cardiac surgery requiring cardiopulmonary bypass.

Not a fit: Patients who are not undergoing cardiac surgery or those with preoperative oxygen saturation levels below 90% may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of lung injury in children undergoing heart surgery, potentially reducing complications and improving recovery times.

How similar studies have performed: While there is existing literature on lung injury post-CPB, this specific focus on neutrophil profiling in pediatric patients is relatively novel and has not been extensively tested.
