Blood Transfusion, Heart Surgery, Hemolysis
Conditions
Brief summary
This study aims to learn more about blood management in children undergoing heart surgery, such as the right amounts, and the best blood products, to administer. It also aims to develop a mathematical model that may help researchers better predict and treat patients who need blood transfusions during heart surgery.
Interventions
Discarded blood samples will be taken from routine clinical labs drawn during and after heart surgery.

Eligibility
Inclusion criteria
* pediatric patients under 18 years of age undergoing cardiac surgery with clear prime on cardio-pulmonary bypass (CPB) at Boston Children's Hospital (BCH).
Exclusion criteria
* patients with known hemolytic disorders, patients on nitric oxide preoperatively, and patients found to have abnormal coagulation on routine preoperative assessment. Patients receiving heparin, American Society of Anesthesia (ASA) status, apixaban, warfarin, or bivalirudin held appropriately (i.e. for elective surgery) will not be excluded
Design outcomes
Primary
| Measure | Time frame |
