Abstract
Some physiological parameters of the agamid lizard (Agama agama agama) were studied after intramuscular injection of ketamine hydrochloride with or without diazepam. Heart rates and electrocardiograms were recorded. Respiratory rates were also monitored before and during anaesthesia. The study showed that ketamine given at a dose of 20-30 mg/kg body weight intramuscularly provides optimal anaesthesia for surgical procedures on the agamid lizard.
