Use of propofol to manage seizure activity after surgical treatment of portosystemic shunts.

The anaesthetic agent propofol has anticonvulsant properties and has been used in the treatment of refractory status epilepticus in human medicine. This report describes the use of propofol in four cats and one dog with naturally occurring seizures following surgical attenuation of single extrahepatic portosystemic shunts. Two of the animals had seizures that were unresponsive to other anticonvulsants.

Sample Population: 863 dogs and cats undergoing clean surgical procedures.

Copper associated acute hepatic failure in a dog.

A 1.5-year-old Dalmatian was examined because of vomiting, weight loss, and high serum activities of alanine aminotransferase and aspartate aminotransferase. Abdominal ultrasonography revealed normal appearing hepatic structure with echogenicity, but histologic examination of hepatic biopsy specimens revealed extensive necrosis of hepatocytes involving the centrilobular areas.
