Suspected Anaphylactic Reaction to Ketamine in 3 Yucatan Swine (Sus scrofa).

Suspected Anaphylactic Reaction to Ketamine in 3 Yucatan Swine (Sus scrofa). Comp Med. 2019 Oct 04;: Authors: Wallace CK, Bell SE, LaTourette Ii PC, Miedel EM, Carty AJ, Philips BH Abstract This case series describes the clinical courses of 3 juvenile Yucatan miniature swine (Sus scrofa) that experienced a suspectedanaphylactic reaction to ketamine hydrochloride during premedication for protocol-related surgery. All 3 swine rapidly developed diffuse erythema shortly after injection with ketamine-containing drug combinations. Clinical signs ranged from tachycardia and erythema alone to tachycardia and erythema followed by respiratory and cardiac arrest. Ketamine was considered the most likely cause of these reactions because it was the only agent in the premedication sedation combination that was used in all 3 swine. Subsequent intradermal skin testing confirmed this suspicion. With supportive care measuresand standard medical interventions for anaphylaxis, all 3 animals recovered well and went on to be successful experimentalsubjects when an alternative anesthetic regimen that did not contain ketamine was used. To our knowledge, this report is the first description of a suspected adverse ketamine reaction of this type in swine despite the widespread use of the drug in this species. Ketamine anaphylaxis is rare in people, but the few cases described presented with symptoms similar to the clinical signs seen in the pigs in this report....
