Recently, aprotinin has been demonstrated to be effective in reducing post-operative bleeding after open heart surgery. The aim of this study was to evaluate the effectiveness of high dose aprotinin in patients undergoing redo open heart surgery in whom perioperative bleeding is generally increased. Fifty-eight patients, mean age 55 years, underwent a second open heart surgery for single valve replacement in 37 patients (mitral or aortic), for double valve replacement in 16 patients and for coronary artery by-pass grafting in 4 patients. In 30 of the 58 patients (Group A) aprotinin was infused with the following scheme: 2 million KIU in 30 minutes during induction of anesthesia, 2 million KIU in the priming volume of extracorporeal circulation and 500,000 KIU every hour until the end of the surgical procedure. The remaining 28 patients served as control group (Group B). No adverse reactions to aprotinin were observed. There was no significant difference in cardiopulmonary by-pass time and minimum temperature achieved between the two groups of patients. During the operative day blood loss was significantly lower in group A than in group B (492 +/- 336 ml vs. 628 +/- 273 ml) (p < 0.01). This difference was not significant during the following days. However 3 days after the operation a still significant difference was reported in total blood loss between group A and group B (816 +/- 507 ml vs. 1018 +/- 373 ml) (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

D007611 Aprotinin A single-chain polypeptide derived from bovine tissues consisting of 58 amino-acid residues. It is an inhibitor of proteolytic enzymes including CHYMOTRYPSIN; KALLIKREIN; PLASMIN; and TRYPSIN. It is used in the treatment of HEMORRHAGE associated with raised plasma concentrations of plasmin. It is also used to reduce blood loss and transfusion requirements in patients at high risk of major blood loss during and following open heart surgery with EXTRACORPOREAL CIRCULATION.
