Effects of aprotinin on hemorrhagic complications in ARDS patients during prolonged extracorporeal CO2 removal.

Abstract

The effects of aprotinin, a broad-based proteinase inhibitor, in the management of hemorrhagic complications during prolonged venovenous extracorporeal CO2 removal in patients with adult respiratory distress syndrome are not evaluated. In two patients, aprotinin infusion was added to heparin to treat bleeding, occurring after few days of bypass and responsible for respiratory and hemodynamic deterioration. After aprotinin infusion (loading dose of 2 x 10(6) kIU followed by a continuous infusion of 5 x 10(5) kIU/h) combined with heparin, bleeding vanished until the end of bypass.
