A total of thirty-three immobilization procedures with Queensland koalas were conducted between 1976 to 1981 at the San Diego Zoo (Table 1). These included twelve cases using ketamine alone, twenty with a ketamine/xylazine combination and one with a ketamine/acepromazine/nitrous oxide combination; no anesthetic mortalities or major complications were encountered. All injections were given intramuscularly in the biceps femoris muscle mass.
