The aim of the present study was to evaluate the anesthetic and cardiorespiratory effects of tiletamine/zolazepam and the effect of flumazenil on the recovery from tiletamine/zolazepam anesthesia in the pig. Six Landrace and Yorkshire cross-bred pigs (three females and three males, 3-4 months old) weighing 35.8 ± 1.7 kg were used in this study. Pigs were given tiletamine/zolazepam intramuscularly at a dose of 4.4 mg kg(-1) (2.2 mg kg(-1) tiletamine and 2.2 mg kg(-1) zolazepam) of body weight. Twenty minutes after the administration of tiletamine/zolazem, the pigs were given saline solution (control, Group TZ) or given flumazenil intravenously at a dose of 0.08 mg kg(-1) of body weight (Group TZF). Anesthesia and recovery times, scores of anesthetic effects and cardiorespiratory variables were recorded for each pig. There was a significant difference between the duration of tiletamine/zolazepam anesthesia with and without the antagonist. Flumazenil significantly shortened the recovery time. A significant difference in blood gas variables was observed between the two groups. The anesthetic effects induced by tiletamine/zolazepam could be reversed successfully and safely by flumazenil alone. Therefore, flumazenil administration could be considered in cases in which quick recovery is required in pigs.

D005442	Flumazenil	A potent benzodiazepine receptor antagonist. Since it reverses the sedative and other actions of benzodiazepines, it has been suggested as an antidote to benzodiazepine overdoses.	Flumazepil,Anexate,Lanexat,Ro 15-1788,Romazicon,Ro 15 1788,Ro 151788

D000777	Anesthetics	Agents capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
