To analyze the anesthetic management for neurosurgery using intraoperative magnetic resonance imaging (iMRI).
Thirty patients with intracranial tumor received MRI for preoperative safety screening and the operation was performed with general anesthesia and support by MRI-compatible machines. The operative time, frequency and duration of MRI, MRI-related time (from the preparation for MRI to the beginning of the surgery), time delay by MRI, body temperature at the initial iMRI and special issues related to the scanning and perioperative anesthesia were recorded.
Thirty patients successfully completed the operations without any incidents related to anesthesia or scanning. The mean frequency of MRI was 1.8, the mean duration of MRI was 29.24 ∓ 10.10 min, and the MRI-related time was 43.83 ∓ 10.23 min; the time delay MRI was 92.63 ∓ 28.31 min, and the body temperature was significantly higher at 2 h after MRI than that after induction.
In the anesthetic management for neurosurgery with iMRI, the anesthesiologists should focus on the safety precaution and anesthetic modulation according to the special environment and procedure of iMRI.
分析术中磁共振成像（iMRI）在神经外科手术中的麻醉管理。
30例颅内肿瘤患者术前行MRI检查以进行术前安全筛查，手术采用全身麻醉并在MRI兼容设备支持下进行。记录手术时间、MRI的频率和时长、MRI相关时间（从准备MRI到手术开始）、MRI导致的时间延迟、首次iMRI时的体温以及与扫描和围手术期麻醉相关的特殊问题。
30例患者均成功完成手术，未发生任何与麻醉或扫描相关的事件。MRI的平均频率为1.8次，MRI的平均时长为29.24±10.10分钟，MRI相关时间为43.83±10.23分钟；MRI导致的时间延迟为92.63±28.31分钟，MRI后2小时的体温明显高于诱导后体温。
在iMRI神经外科手术的麻醉管理中，麻醉医生应根据iMRI的特殊环境和流程，重点关注安全预防措施和麻醉调整。
