abstract
オープンMRI設置手術室で25例の麻酔を経験した。MRI設置手術室では術中にMRI画像を判断材料として手術をすすめるため,MRI画像へのノイズ混入対策が必要である。また,MRI磁場の影響で術中にモニター機器や麻酔器が誤動作を起こす可能性があるため,MRI非対応機器からの画像ノイズの遮断対策として,電子機器から発生するノイズの軽減には特殊シールドボックスやイキソルメッシュを使用し,手術室外からのノイズには手術室全体にシールド工事を行った。MRIが発生させる磁場による電子機器の誤動作・故障対策は,オープンMRIの磁場が5ガウス以下となる範囲に電子機器や手術器具を置くことで対応した。問題の克服に加えて,医療機器からのデータの無線通信により,ケーブル類をなくすことでMRI撮影時の患者移動の簡素化をはかり,安全性を高めることができた。
abstract
We provided anesthesia care for 25 patients in an open MRI operating room and summarized here our experience. When surgeons use MRI during surgery, the presence of noise in the images caused by other electronic equipment in the area often hinders accurate diagnosis. In addition, malfunction of monitoring and anesthesia equipment during surgery due to the MRI magnetic field created during an MR examination can occur. In order to prevent imaging interference affecting equipment not compatible with MRI, we utilized 2 specially prepared shield boxes and wrapped the personal computer used for coordinating the data with a mesh-like cloth made by Ixol-mesh. In addition, we prepared a shielded operating room in order to block noise from the outside. To prevent malfunction of the surgical and electronic instruments, we kept them outside the magnetic field of 5 Gauss or lower to minimize the magnetic effect generated with MRI. Furthermore, patient safety during MRI imaging was improved by establishing a wireless communication system to feed data from medical devices, which allowed elimination of cabling.
