A Technique for Paravertebral Anesthesia in Korean Cattle

한우(韓牛)의 척추측마취(脊椎側痲醉)

Paravertebral anesthesia for operation of abdominal wall in Korean cattle were effectively accomplished with the following technique. Any problems in surgical procedure were not observed under the block of ventral branches of the last thoracic nerve and the first and second lumbar nerves with the administration of preanesthetic. The site of injection for blocking of ventral branches of the thirteenth thoracic nerve were approximately 5cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthetic was injected immediately anterior to the transverse process of the first lumbar vertebra through thin site. The block of ventral branches of the first and second lumbar nerves were obtained by injecting 10ml of local anesthetic immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively.
