Disseminated intravascular coagulation syndromes.

Current concepts of the etiology, pathophysiology, diagnosis and management of fulminant as well as low-grade disseminated intravascular coagulation have been presented. Considerable attention has been devoted to interrelationship within the hemostasis system. Only by clearly understanding these pathophysiological interrelationships can the clinician and laboratory scientists appreciate the divergent and wide spectrum of often confusing clinical and laboratory findings in patients with disseminated intravascular coagulation. Many therapeutic decisions to be made in these patients are controversial and will remain so until more series of patients are published about specific therapeutic modalities and survival patterns. Also, therapy must be highly individualized depending on the nature of DIC, age, etiology of DIC, site and severity of hemorrhage or thrombosis and hemodynamic and other clinical parameters. Many syndromes which are organ specific share common pathophysiology with disseminated intravascular coagulation but are typically identified as an independent disease entity, such as hemolytic uremic syndrome, adult shock lung syndrome, eclampsia, and many other isolated "organ-specific" disorders. Many of these similar disorders, some systemic and some organ specific or multi-organ specific are listed in Table 8.
