There are no safe anesthetic agents, there are no safe anesthetic procedures. There are only safe anesthetists.—Robert Smith, MDa
The American Animal Hospital Association (AAHA) offers comprehensive “recommendations for preanesthetic patient evaluation and examination, selection of premedication, induction and maintenance drugs, monitoring, equipment, and recovery. In recognition of differences among practices, these guidelines are not meant to establish a universal anesthetic plan or legal standard of care.”
