Cardiac surgery in adults and children without use of blood.

Since 1968, following Cooley's and Zubiate's group presentation, our team has been using extracorporeal circulation (ECC) with hemodilution without use of blood for priming of the circuit. Progressively this technique, that was only reserved to the Jehovah's Witnesses, became routine. Whereas in 1980, 30% of the patients operated by our group had not received any blood products during their stay in hospital, in the last few years, 1987-95, more than 80% of the patients could benefit from this technique.

Heparin removal in three intraoperative blood savers in cardiac surgery.

The aim of the study was to compare the residual heparin in the composition of autologous blood retransfusion units harvested during cardiac surgery under extra-corporeal circulation with three different intraoperative autologous blood savers. In this institutionally approved study, thirty patients undergoing CABG were randomly assigned to three groups according to the intraoperative blood saver used during the procedure: {HAEMONETICS Cell Saver IV (n=10)--DIDECO/SHILEY STAT (n=11)--BRAT 250 (n=9)}. Anaesthesia and conduct of bypass were identical for all patients.
