AbstractAcute pancreatitis was induced in 19 anesthetized dogs by retrograde injection of bile mixed with trypsin into the pancreatic duct. Two groups, of six animals each, were treated with intravenous infusion of synthetic antiproteases: gabexate mesilate and nafamostat mesilate in doses of 1 mg/kg per hr. One group of seven animals remained untreated. Two untreated dogs died during the experiment. All the treated dogs survived. Hemodynamic data were monitored hourly during a 6-hr observation period. In the untreated animals, cardiac output, mean arterial pressure, and left ventricular stroke volume decreased rapidly; an increase of pulmonary vascular resistance and systemic vascular resistance was observed. Synthetic antiproteases, given as a therapy, improved the hemodynamic parameters significantly and prevented the animals from developing shock. Gabexate mesilate and nafamostat mesilate seem to be of value in the treatment of experimentally produced acute pancreatitis in dogs.
