Induction to inhalation anaesthesia in agamid lizards with alfaxalone

Abstract

The aim of this study was to evaluate intravenous anaesthesia with alfaxalone for tracheal tube insertion in three species of agamid lizards. Alfaxalone, at a dose rate of 5 mg/kg, was administered intravenously to 80 inland bearded dragons (Pogona vitticeps), 10 Rankin's dragons (Pogona henrylawsoni) and 10 Chinese water dragons (Physignathus cocincinus) following 24 h of fasting. The righting reflex in inland bearded dragons, Rankin's dragons and Chinese water dragons was lost within 12-45 s (17.52 ± 8.80 s), 15-40 s (24.60 ± 9.61 s) and 12-40 s (21.70 ± 9.53 s), respectively. The mean tracheal tube insertion time for inland bearded dragons, Rankin's dragons and Chinese water dragons was 23.61 ± 10.91 s, 35.30 ± 14.71 s and 32.00 ± 14.32 s, respectively. Intravenous use of alfaxalone proved to be a suitable method for safe tracheal tube insertion and induction to inhalation anaesthesia in agamid lizards.
