The research team proposes a prospective, observational study to better understand how TEG can be useful in guiding clinical practice in the Main OR for subject's undergoing high transfusion risk surgeries. Intraoperatively, transfusion of blood products is frequently required to restore oxygen carrying capacity, perfusion and improve coagulation. Both under and over transfusion pose significant risks, particularly to pediatric patients with small starting intravascular volumes. Thromboelastography (TEG) is a validated method of dynamically assessing intraoperative coagulopathy via functional assay. However, while FDA approved and widely used in the adult setting, TEG is not commonly utilized in the setting of bleeding pediatric patients. Recently, TEG has been made available at BCH for clinical purposes and is being used solely in the cardiac surgery setting. The investigators aim to provide TEG data for non-cardiac pediatric surgical cases with a high risk of intraoperative blood loss in order to assess the impact of this tool on intraoperative management.
