The authors developed safe standard sedation and general anesthesia procedures for adults and children, including adequate physiologic monitoring, during magnetic resonance (MR) imaging. Six-year results are reported from one institution; 75% of the 600 patients per year who require sedation or anesthesia are children who require sedation only. Testing was done to determine MR compatibility of various types of equipment essential for monitoring and supporting sedated or anesthetized patients in 1.0- and 1.5-T MR imagers. Use of sedation procedures that include oral chloral hydrate after sleep deprivation resulted in a failure rate of 3.8% in sedating outpatient children. Every physiologic parameter that can be monitored under normal circumstances in the critical care unit or operating room can be monitored during MR imaging. Our experience indicates that with careful consideration of the unique MR environment and with rigorous testing of monitoring equipment, MR imaging can be performed safely in sedated or anesthetized patients.
作者们制定了针对成人和儿童的安全标准镇静及全身麻醉程序，包括在磁共振（MR）成像期间进行充分的生理监测。本文报告了一家机构的六年研究结果；每年600例需要镇静或麻醉的患者中，75%是仅需镇静的儿童。对用于在1.0T和1.5T MR成像仪中监测和支持镇静或麻醉患者的各种类型设备进行了MR兼容性测试。采用包括睡眠剥夺后口服水合氯醛的镇静程序，门诊儿童镇静失败率为3.8%。在重症监护病房或手术室正常情况下可监测的每一项生理参数，在MR成像期间均可进行监测。我们的经验表明，通过仔细考虑独特的MR环境并对监测设备进行严格测试，可在镇静或麻醉患者中安全地进行MR成像。
