07. Neurosurgical Management of Mature Cattle Based on a New Neurosurgical Operating Table and the Development of Monitoring Techniques


  We have developed a neurosurgical operating table for neurosurgery using inhalation anesthesia with isoflurane on mature cattle. Complications such as regurgitation and severe rumen tympany did not occur with isoflurane anesthesia.
  Intracranial pressure (ICP) and mean arterial presssure in the sternal recumbent position using neurosurgical operating table were lower than in the right lateral recumbent position. In nonanesthesia-standing mature cattle, the mean ICP was approximately 10 mmHg. Anorexia was observed, when the mean ICP exceeded 20 mmHg, and depression was observed, when the mean ICP exceeded 35 mmHg.
