BackgroundWith the withdrawal of aprotinin from worldwide marketing in November 2007, many institutions treating patients at high risk for hyperfibrinolysis had to update their therapeutic protocols. At our institution, the standard was switched from aprotinin to ε-aminocaproic acid (EACA) in all patients undergoing cardiac surgery with extracorporeal circulation including neonates. Although both antifibrinolytic medications have been used widely for many years, there are few data directly comparing their blood-sparing effect and their side-effects especially in neonates.MethodsPerioperative data from 235 neonates aged up to 30 days undergoing primary cardiac surgery were analysed. Between July 1, 2006 and November 5, 2007, all patients (n=95) received aprotinin. Starting November 6, 2007 until December 31, 2009, all patients (n=140) were treated with EACA. The primary outcome criterion was blood loss; secondary outcome criteria were transfusion requirements, renal, vascular, and neurological complications and also in-hospital mortality.ResultsAll descriptive and intraoperative data variable were similar. Blood loss was significantly higher in the EACA group (P=0.001), but there was no difference in the rate of re-operation for bleeding (P=0.218) nor the number of transfusions. There were no differences in the incidences of postoperative renal, neurological, and vascular events or in-hospital mortality.ConclusionsIn neonatal patients undergoing cardiac surgery, the switch to EACA treatment led to a higher postoperative blood loss. However, there were no differences in transfusion requirements or major clinical outcomes.
