Alterations of glucose levels in the blood and the anterior eye segment of rabbits exposed to ketamine-xylazine anaesthesia.

In rabbits the blood glucose and consequently the aqueous humour glucose levels were increased under general anaesthesia by Ketanest-xylazine. Between 60 and 90 min of the general anaesthesia the average blood glucose levels were found to be three times and those of the aqueous humour twice the normal values. After more than 75 min of anaesthesia the glucose levels tended to be further elevated.
