[Prevention and treatment of postoperative septic MOF and DIC and efficacy of blood purification].

Pathophysiologic concept of SIRS has been proposed for the better management of postoperative severe infection and septic MOF, and the concept has been found to be very useful. It is very important to identify the high risk SIRS patients of the development of septic MOF and to treat those patients aggressively to prevent the development of septic MOF. In the prevention and treatment of septic MOF, the blood purification has been found to be very effective. Among the blood purifications, continuous blood purification, such as continuous hemodiafiltration (CHDF) should be chosen for this purpose. CHDF has been claimed to be very effective to removal of causative humoral mediators from the blood stream. The concept of DIC has been changed recently and the concept of DII (disseminated intravascular inflammation) should be applied instead of DIC, since the main feature of this pathologic condition is the damage of endothelial cells due to extensive systemic inflammation.
