Reducing bleeding during extracorporeal circulation interventions by high doses of aprotinin

: The great risk of severe infectious diseases transmission through blood transfusion, has increased during the last years the effort to reduce the bank blood and its derivates use. Many techniques have proposed to achieve this purpose during and post cardiopulmonary bypass: normovolemic hemodilution, perioperative blood autotransfusion, postoperative return of extra corporeal circuit and chest drains blood and the particular use of some drugs. In the last few years several reports have been presented in the literature concerning the reduction of intra and postoperative bleeding in cardiac surgery by high dose Aprotinin administration. A randomized study with the use of this pharmacologic agent is presented: a group of patients was treated with Aprotinin (shared in two subgroups receiving respectively a different dose of the drug) and a control group. The results were highly encouraging both because of the reduction of peri and postoperative bleeding and because of the bank blood use important reduction.
