Beneficial effects of recombinant human activated protein C in a ewe model of septic shock*

In this clinically relevant model of septic shock due to fecal peritonitis, administration of APC had beneficial effects on hemodynamic variables, gas exchange, lactic acidosis, and coagulation abnormalities. Higher colloid oncotic pressures and lower lung wet/dry ratios at autopsy suggest preserved endothelial integrity. APC administration resulted in prolonged survival.
