Prevention of endotoxin‐induced arterial hypoxaemia and lactic acidosis with flunixin meglumine in the conscious pony

Abstract
Bacterial endotoxin injected i.v. into conscious ponies produced alterations in cardiopulmonary and gastrointestinal function. Specifically, tachypnea, dyspnea, hypoxemia, colic, lactic acidosis and diarrhea resulted from administration of 10 .mu.g/kg Escherichia coli endotoxin. Pretreatment of the ponies with a potent prostaglandin synthetase inhibitor, flunixin meglumine, prevented these ill effects of endotoxin.
