Abstract:

Objective: To introduce the application process of a mixed reality (MR)-based multimodal head-mounted intraoperative neurosurgical montioring system and its integration into intraoperative applications, and to evaluate the clinical efficacy of this system for monitoring during neurosurgical intraoperative radiotherapy. Methods: A MR-based multimodal head-mounted intraoperative neurosurgical monitoring system was used to assist anesthesiologists in real-time monitoring of patients' vital signs and operation area during radiotherapy in neurosurgical surgery. Before the use of the system, the simulation test was used to record the delay time of video signal streaming. Before the start of radiotherapy in neurosurgery, the system preparation time was recorded. After the operation, an self-designed electronic questionnaire was used to investigate the satisfaction of anesthesiologists with the use of the system. Results: The system has been successfully used in 23 cases of neurosurgical intraoperative radiotherapy. No technical failures or related complications occurred. The quantitative delay test showed median time of video signal streaming delay measured by simulation test was 160 ms. The system preparation time decreased from 32 min at the beginning of the study to 4-5 min. A total of 14 anesthesiologists were received the questionnaire survey, and the satisfaction score was 30.43. Conclusions: The MR-based multimodal head-mounted intraoperative neurosurgical monitoring system is applied during neurosurgical intraoperative radiotherapy to assist anesthesiologists in real-time monitoring of patients' vital signs and the environment of the operation area, which has a good prospect of popularization and transformation.

摘要：

目的: 介绍基于混合现实技术的多模态头戴式神经外科术中监测系统使用流程, 并探讨将其整合至神经外科术中放射治疗的可行性。方法: 采用基于混合现实技术的多模态头戴式神经外科术中监测系统, 辅助神经外科术中放射治疗期间麻醉医师对患者生命体征和术区的实时监控。使用前先采用模拟试验记录视频信号串流延迟时间, 神经外科术中放射治疗开始前记录术前系统准备时间, 术后采用自行设计的电子问卷调查麻醉医师使用满意度。结果: 共23例次的神经外科术中放射治疗过程中成功应用该术中监测系统。定量延迟测试模拟试验测得视频信号串流延迟中位时间为160 ms, 术前系统准备时间由初期的32 min降至4 ~ 5 min, 共14名麻醉医师接受问卷调查, 满意度达30.43分。结论: 基于混合现实技术的多模态头戴式神经外科术中监测系统应用于神经外科术中放射治疗期间, 辅助麻醉医师实时监测患者生命体征及术区环境具有较好的可行性, 有很好的推广和转化应用前景。
