Sepsis model with reproducible manifestations of multiple organ failure (MOF) and disseminated intravascular coagulation (DIC).
A new reproducible animal model of sepsis was established to investigate interrelationship between disseminated intravascular coagulation (DIC) and multiple organ failure (MOF). Sepsis was induced by injecting fecal suspension into bile duct of rabbits, in which the amount of endotoxin in circulating blood was gradually increased and manifestations of sepsis were confirmed. During 9 hours' observation period, an occurrence of hypercoagulable state leading to DIC was evidenced by the abnormal hemostaseological parameters. Simultaneously the elevation of plasma bilirubin and creatinine levels was observed, indicating the presence of liver and kidney failure, which was confirmed by the histological examination. Thereby, the present sepsis model complicates DIC and MOF with high reproducibility, which is relevant to sepsis seen in clinical patients.
