Clinical Trial Summary

Cardiac surgery needs the use of cardiopulmonary bypass. During this time, it is necessary to prevent thrombosis with high level of heparin and to control the good efficiency with a point of care test. Investigators want to test if two different devices, Hemochron and Istat, are giving similar results.


Description:

The management of the extracorporeal circulation (ECC) for cardiac surgery requires massive anticoagulation of the circuit by heparinization at 300 IU / kg of unfractionated heparin (HNF). To ensure an adequate level of safety, it is necessary to monitor the effectiveness of this dose of NHF. Several point of care monitors measuring activated coagulation time (ACT) are available on the market. Among these are the Hemochron (currently used routinely in the institution) and the IStat. These two monitors have been compared in adult cardiac surgery without deep hypothermia, but there is no comparative study in pediatric cardiac surgery. The result of the ACT being dependent, in addition to heparinization, the platelet count, the fibrinogen level and the body temperature, it is therefore necessary to test the approval and the interchangeability between the monitors in different clinical situations . The objective of this study is to reproduce the results published in adults and to compare these two monitors in pediatrics.

Outcome

Type Measure Description Time frame Safety issue
Primary Agreement of ACT measurement with Istat and Hemochron Investigators will use linear regression correlation, ROC curves analysis
Istat and Hemochron will be measured at 5 time points :
induction,
2 minutes after heparin loading,
10 minutes after the stat of cardiopulmonary bypass or after heparin,
30 minutes after the start of cardiopulmonary bypass or after heparin,
2 minutes after protamin
Maximum 6 hours (time of surgery)
Primary Interchangeability of ACT measurement with Istat and Hemochron Investigators will use linear regression correlation, ROC curves analysis
Istat and Hemochron will be measured at 5 time points :
induction,
2 minutes after heparin loading,
10 minutes after the stat of cardiopulmonary bypass or after heparin,
30 minutes after the start of cardiopulmonary bypass or after heparin,
2 minutes after protamin
Maximum 6 hours (time of surgery)
