Sedation in Green Iguanas
Reptile · Iguana iguana · typical adult weight 1.00–5.00 kg
4 cited drugs treat Sedation in green iguanas: Alfaxalone, Flumazenil, Ketamine, Midazolam.
Pharmacologic sedation for diagnostic procedures, minor surgical interventions, and pre-anaesthetic premedi-cation. α2 agonists (dexmedetomidine, medetomidine), phenothiazines (acepromazine), and benzodiazepines (midazolam) form the backbone of veterinary protocols.
