When cesarean section, mastotomy, and rumenotomy were performed, the author preferred spinal epidural anesthesia to that produced by simple local infiltration, because of a safer and more convenient technic. For that anesthesia 10 to 15 ml per head of 5% procaine hydrochloride was injected with a needle 10 cm long and at least 0.2 cm wide. The best site of injection was the L. 1-L. 2. The T. 13-L. 1 and the L. 2-L. 3 were also available.
The straight distance between the surface of the skin and the spinal dura mater was 8 cm in Holsteins, 6 cm in Jerseys, and 7 cm in Japanese Black oxens.
