 Specific Objectives: During redo sternotomy procedures there is significant anti-inflammatory response which occurs and plays a role in increasing amount chest tube output, blood loss, renal injury, hepatic injury and ultimately patient morbidity andor mortality. The proposed study will help to know if antifibrinolytic agents are beneficial in reducing the anti-inflammatory response produced and which of the two drugs EACA or TXA, has a better anti-inflammatory profile when used in a similar setting for patients undergoing pediatric cardiothoracic surgery.
