| Abstract: | Application of commonly used volatile anesthetics after brain ischemia onset (post-treatment) provides neuroprotection in rodents. To further test its translational potential, this study was designed to determine whether isoflurane post-treatment induced neuroprotection in rabbits after embolic stroke. White male New Zealand rabbits received intra-carotid injection of clots when they were awake. Some rabbits were exposed to 2.5% isoflurane for 1 h at 5 min after the injection. Isoflurane post-treatment increased the tolerance of rabbits to the amount of clots. Isoflurane post-treatment also reduced brain infarct volumes and plasma S100B 3 days after the injection of 5 mg clots and improved neurological deficit scores after the stroke. Isoflurane post-treatment improves neurological outcome in rabbits after embolic stroke. |
