Bypass Clear Priming VSD Cardiopulmonary Bypass Circuit Reduce Bypass Associated Inflammation?

Sponsor: Seattle Children's Hospital

Summary

The purpose of this trial is to study if priming the pump used during cardiac surgery with non-blood fluids instead of donated blood products reduces the inflammation that occurs after heart surgery. The study will focused on pediatric participants who require open heart surgery to repair certain types holes in the heart. Typically for pediatric patients, the cardiopulmonary bypass pump is "primed" (filled) with donated blood products. This project is going to test if the exposure to these blood products causes inflammation. Patients experience significant inflammation (swelling) after undergoing cardiopulmonary bypass. This inflammation can interfere and slow down the patient's recovery from cardiac surgery. With this project, the investigator are studying if filling the bypass pump with non-blood products reduces the bypass-associated inflammation. The investigators are also studying if using non-blood fluids to fill the bypass pump reduces bypass associated side effects. The investigators are also trying to understand how the inflammation starts. The investigators also want to study genetic material called DNA that is collected from a person's blood. Instructions for the body are contained in parts of DNA called genes. Genes determine things like hair and eye color. The investigator hope by studying genes the investigator can learn more about the inflammation that occurs after heart surgery, but the investigators might use participant's genetic information to study other diseases or conditions other the inflammation that occurs after heart surgery. The investigators will be studying the recovery of 60 participants between 1 month to 18 months of age who require open heart surgery to repair ventricular septal defects (VSDs), a congenital heart defect where there a hole between the lower chambers of the heart. Participants will: Allow for information about how the participants recover from surgery to be collected. Allow blood samples during and after surgery to be collected to understand how the markers of inflammation change between the two groups (blood versus non-blood priming).
