NCT06721455

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.

Outcome Measures

Primary Outcomes (1)

  • Intraoperative hemolysis during pediatric cardiac cardio-pulmonary bypass (CPB) cases as assessed using the plasma free hemoglobin assessment

    1 day (during cardio-pulmonary bypass)

Secondary Outcomes (1)

  • In vitro salvaged red blood cells (RBCs) co-incubation with patients' plasma for hemolysis assessment compared to patients' baseline RBCs

    1 day

Study Arms (1)

Children having heart surgery

Children under 18 years of age having heart surgery with cardio-pulmonary bypass at Boston Children's Hospital

Other: blood sampling

Interventions

Discarded blood samples will be taken from routine clinical labs drawn during and after heart surgery.

Study Population

Pediatric patients under 18 years of age undergoing cardiac surgery with clear prime on cardio-pulmonary bypass (CPB) at Boston Children's Hospital (BCH).

You may qualify if:

  • pediatric patients under 18 years of age undergoing cardiac surgery with clear prime on cardio-pulmonary bypass (CPB) at Boston Children's Hospital (BCH).

You may not qualify if:

  • 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
