title: Pathologic changes induced by an euthanasia agent.
abstract: Dogs and cats killed by intravenous injection of either 0.3 ml/kg body weight T-61 or 100 mg/kg body weight pentoarbital and necropsied at less than 5 minutes or at 15 minutes after injection did not have gross or microscopic pathological changes. However, dogs and cats killed with T-61 at a dose of 1.0--1.5 ml/kg body weight and necropsied at 15 minutes after injection had significant gross and microscopic pathological lesions. Grossly, the lungs were severely edematous, did not collapse, and were deep red. Microscopically, the lungs had severe pulmonary edema and endothelial necrosis. Endothelial swelling of glomerular tuft vessels was also present. These lung and kidney lesions are classified as an euthanasia artefact.
