Standard methods as well as promising protocols of inhalant, intravenous and intramuscular anaesthesia, adequate analgesia and continuous monitoring have being established for large as well as for medium size reptiles, including captive lizards within the last ten years1-4. The aim of this master class presentation is to describe in details (step by step) the valuable anaesthetic protocols for small lizards (lizards with body weight lower than 100 g).
The experiences of practical use of the combination of alfaxalone (IV, IM) with tramadol or morphine, NSAIDs and benzodiazepines in leopard geckos, young veiled chameleons and young bearded dragons in clinical practice will be presented and discussed in details, with the support of colour pictures and videos. After fasting for 24 hours the patients receive combination of meloxicam (0.5 - 1 mg/kg) with tramadol (10 mg/kg) intramuscularly, 25 – 35 minutes before the alfaxalone administration. Alfaxalone at a dose rate of 5 mg/kg is administered intravenously (ventral tail vein) to veiled chameleons (Chamaeleo calyptratus) and bearded dragons (Pogona vitticeps). Alfaxalone at a dose rate of 15 mg/kg is administered intramuscularly to veiled chameleons (Chamaeleo calyptratus), bearded dragons (Pogona vitticeps) and leopard geckos (Eublepharis macularius).
After the intravenous administration of alfaxalone, all clinically important reflexes were lost within 45 seconds; after the intramuscular administration of alfaxalone, all clinically important reflexes disappeared within 3 minutes. Intravenous as well as intramuscular use of alfaxalone proved to be suitable methods of smooth anaesthesia or as induction for inhalation anaesthesia in very small reptiles.
