Alfaxalone anaesthesia in the green iguana (Iguana iguana)

Intramuscular administration of alfaxalone is a simple, rapid and reliable means of achieving relatively brief sedation or anaesthesia in healthy green iguanas. A dosage of 10 mg kg−1 provides light sedation, appropriate for examination and venipuncture; 20 mg kg−1 provides a level suitable for minor procedures or for endotracheal intubation and supplementation with inhalational anaesthesia; 30 mg kg−1 produces an anaesthetic plane suitable for surgical procedures of limited duration (up to 40 minutes).
