Front Aging Neurosci:胰岛素鼻内给药或可防止全麻后认知功能的损害

2017-05-26 MedSci MedSci原创

全身麻醉会增加术后认知功能障碍的发生风险,尤其是老年人和易感个体。近年来动物模型研究对麻醉对术后认知功能障碍影响提供了一些有价值的证据研究,但还有许多有待进一步研究的地方。 本研究利用不同年龄和疾病状态的小鼠,采用Morris水迷宫(MWM)测试发现麻醉暴露后2-6天异丙酚和七氟醚麻醉可显著降低小鼠的空间学习记忆能力。在野生型(WT)老年小鼠(17–18月龄)和3xTg-AD(阿尔茨海默病(

全身麻醉会增加术后认知功能障碍的发生风险,尤其是老年人和易感个体。近年来动物模型研究对麻醉对术后认知功能障碍影响提供了一些有价值的证据研究,但还有许多有待进一步研究的地方。

本研究利用不同年龄和疾病状态的小鼠,采用Morris水迷宫(MWM)测试发现麻醉暴露后2-6天异丙酚和七氟醚麻醉可显著降低小鼠的空间学习记忆能力。在野生型(WT)老年小鼠(17–18月龄)和3xTg-AD(阿尔茨海默病(AD)的三转基因小鼠模型)成年小鼠(7 8个月大),而非成年WT小鼠。

3xTg-AD小鼠麻醉后65天出现长期神经行为学改变。重要的是,麻醉前3天每天胰岛素鼻腔给药(1.75 U /鼠/天)可完全防止麻醉诱导的空间学习记忆和神经行为变化。这些结果表明,老化和AD样脑病理可增加麻醉后的认知功能障碍的易感性,但是鼻内胰岛素给药治疗可以防止麻醉诱导的认知功能障碍。
