Key Points

Outline intraoperative motor evoked potential monitoring protocols and anesthetic management strategies to mitigate spinal cord injury and prevent paraplegia during descending thoracic and thoracoabdominal aortic aneurysm surgery.
Reviewed anesthetic considerations for reliably recording and interpreting intraoperative motor evoked potential signals.
Assessed the procedural impacts of extracorporeal circulation, aortic cross-clamping, and hypothermia on neurophysiological monitoring.
Examined adjunct spinal cord protection strategies, focusing on cerebrospinal fluid drainage protocols.
Motor evoked potential monitoring facilitates timely detection of acute spinal cord ischemia during critical surgical maneuvers.
Extracorporeal circulation, hypothermia, and aortic cross-clamping induce signal alterations that require targeted anesthetic and physiological troubleshooting.
Integration of neurophysiological monitoring with cerebrospinal fluid drainage supports clinical workflows to lower paraplegia risk and improve surgical outcomes.

Abstract

胸部下行大動脈瘤手術，胸腹部大動脈瘤手術において脳脊髄障害はある一定の頻度で発生し，対麻痺は最も重篤な合併症である．運動機能障害が発生する危険性のある手術では術中から運動機能をモニタリングすることで術後の運動機能を温存することが重要である．そのためには運動誘発電位（motor evoked potential：MEP）を安全かつ適切に記録し，その変化を評価できるための麻酔管理が必要になる．MEPの変化があった場合にどのように評価し対応すべきかを示す．大血管手術では体外循環の使用，大動脈遮断や低体温などがありMEPの評価に注意を要する．また脊髄保護戦略の一つである脳脊髄液ドレナージについても概説する．MEPモニタリングや脳脊髄液ドレナージの情報を共有することで，大血管手術における脊髄保護の麻酔管理の一助となり，患者予後の向上に資することを目標とする．
