Understanding how heart-lung machines affect inflammation in children during surgery

Supraphysiologic Shear Stresses Associated with Cardiopulmonary Bypass are Sufficient to Activate RIKP3 Signaling

['FUNDING_R01'] · SEATTLE CHILDREN'S HOSPITAL · NIH-11035150

This study is looking at how a heart-lung machine used during heart surgery for kids can cause inflammation in their bodies, and it aims to find ways to reduce this inflammation to help them recover better after surgery.

What this research studies

This research investigates the effects of cardiopulmonary bypass (CPB) on inflammation in pediatric patients undergoing open-heart surgery. It focuses on how high shear stress from the CPB circuit activates specific signaling pathways in blood cells, leading to systemic inflammation and multi-organ dysfunction. By studying both animal models and patient data, the research aims to identify potential treatments that could mitigate these inflammatory responses and improve surgical outcomes for children. The ultimate goal is to translate these findings into clinical strategies that enhance recovery for neonatal cardiac surgery patients.

Who could benefit from this research

Good fit: Ideal candidates for this research are pediatric patients, particularly neonates, who are scheduled to undergo open-heart surgery requiring cardiopulmonary bypass.

Not a fit: Patients who are not undergoing cardiac surgery or who do not require cardiopulmonary bypass may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment strategies that reduce inflammation and enhance recovery for children undergoing heart surgery.

How similar studies have performed: Previous research has indicated that targeting specific signaling pathways can effectively reduce inflammation in similar contexts, suggesting a promising avenue for this study.
