[Endothoracic anesthesia for artificial anus formation in rabbits].

We succeeded in maintaining anesthesia for artificial anus formation in rabbits using a new anesthetic technique of endothoracic anesthesia. The drug injection through a catheter, which was inserted into the endothoracic fascia at the level of the 11th thoracic vertebra, caused an unilateral anesthesia from the chest down to the lower limb. Artificial anus formation was possible by this endothoracic anesthesia with a help of medetomidine and nitrous oxide.
