摘要
体外循环术后认知功能障碍(POCD)发生率居高不下,严重影响患者预后生活质量。本文总结了体外循环术后POCD的发生机制,包括:炎性反应和氧化应激机制、Tau蛋白的过度磷酸化机制、大脑皮层中血容量和血氧降低机制,并根据其发病机制选择相应的POCD预警指标,以期通过不同技术手段所得结果的交叉印证,最终推进POCD的早期诊断和防治。
The high incidence of postoperative cognitive dysfunction( POCD) after extracorporeal circulation has seriously affected the prognosis and quality of life. Its mechanism may involve the inflammatory response and oxidative stress,the excessive phosphorylation of tau protein,the decreased blood volume and oxygen in the cerebral cortex. Appropriate early warning indicators of POCD after the extracorporeal circulation should be chosen to facilitate the cross validation of the results obtained different technical approaches and thus promote the early diagnosis and treatment of POCD.
