Intraoperative magnetic resonance imaging (iMRI) is an evolving technology used to provide precise intraoperative navigation during a variety of neurosurgical and other types of surgical procedures. Anesthesiologists need to be aware of the unique challenges created by this environment. Failure to recognize the differences between the diagnostic MRI environment and the iMRI environment can compromise the safety of the patient and operating room staff and present logistical problems.
Recent surgical reports herald the uses and benefits of iMRI. However, there are a few in the anesthesia literature addressing the significant benefits and the anesthesia-specific issues this technology creates. We will review recent reports describing anesthetic care of patients in this environment as well as examine the recent surgical and radiologic literature as they relate to issues faced by anesthesiologists.
We describe the design of different iMRI suites as well as provide a breakdown of both patient and equipment issues encountered by anesthesiologists practicing in this environment. Finally, we offer our ongoing experience in this environment and provide suggestions to optimize patient outcomes.
术中磁共振成像（iMRI）是一种不断发展的技术，用于在各种神经外科和其他类型的手术中提供精确的术中导航。麻醉师需要意识到这一环境带来的独特挑战。如果不能认识到诊断磁共振成像环境与 iMRI 环境之间的差异，可能会危及患者和手术室工作人员的安全，并带来后勤问题。
最近的外科报告预示着 iMRI 的使用和益处。然而，在麻醉文献中，只有少数几篇文章讨论了这项技术带来的显著益处和麻醉方面的问题。我们将回顾最近描述在这种环境下对患者进行麻醉护理的报告，并研究最近的外科和放射学文献，了解麻醉师所面临的问题。
我们描述了不同 iMRI 套件的设计，并详细介绍了麻醉师在该环境中遇到的患者和设备问题。最后，我们提供了我们在该环境中的持续经验，并提出了优化患者结局的建议。
