Anesthesia in the rabbit using a combination of ketamine and promazine.

An anesthetic combination of ketamine and promazine (75mg/kg by ketamine content) was tested in 15 male and 15 female adult New Zealand white rabbits. The mean induction time was 9 minutes for both the male and female. Mean duration for anesthesia was 61 minutes for the male and 49 minutes for the female. The mean recovery time was 22 minutes for the male and 33 minutes for the female. The drug combination provided effective anesthesia for a period of 50--60 minutes after a single intramuscular injection.
