| Research Abstract |
There is a possibility that perioperative administered opioids worsen paralysis caused by spinal cord ischemia. To elucidate the effects of opioids in spinal motoneurons and its significance during an ischemic insult, we conducted the electrophysiological experiments. We revealed that the opioids modulated synaptic transmission in spinal motoneurons, however, it did not exacerbate the ischemic injury. Our findings indicate that opioids administration during spinal cord ischemia should be considered as a potential component of anesthetics during aortic surgery.
