When brain tumors are located near the language area, a test to assess language function is required. During the test, it is practical to display combined information obtained from all the equipment so that the surgeon can confirm the patient's response to the tasks. We developed the intraoperative examination monitor for awake surgery (IEMAS) mainly to combine all information so that the language function test could be performed efficiently. The IEMAS has proved to be useful in clinical settings; however, no quantitative evaluation has been performed. This study aimed to demonstrate the clinical usefulness of the IEMAS through comparison of cases with and without IEMAS use in language function test simulation.
The language function test simulator was created to eliminate any uncertain factors, such as symptoms, which vary among patients. Neurosurgeons participated in the test, and the usefulness of the IEMAS was investigated. We analyzed test duration and number of information exchanges between surgeon and examiner.
Total test duration with IEMAS use was significantly shorter than without IEMAS use (116.1 ± 23.1 seconds vs. 147.8 ± 48.7 seconds; P < 0.02). The number of information exchanges between surgeon and examiner was significantly lower with IEMAS use than without IEMAS use (0.2 ± 0.6 times vs. 16.1 ± 15.6 times; P < 0.02).
We compared cases with and without IEMAS use. Total test duration decreased with IEMAS use, and number of information exchanges was reduced, thus demonstrating the usefulness of the IEMAS.
当脑肿瘤位于语言区附近时，需要进行一项评估语言功能的测试。在测试过程中，展示从所有设备获得的综合信息是很实用的，这样外科医生就能确认患者对任务的反应。我们开发术中清醒手术检查监测仪（IEMAS）主要是为了整合所有信息，以便能够高效地进行语言功能测试。IEMAS已被证明在临床环境中是有用的；然而，尚未进行定量评估。本研究旨在通过比较在语言功能测试模拟中使用和未使用IEMAS的病例，来证明IEMAS的临床实用性。
创建语言功能测试模拟器以消除任何不确定因素，如患者之间各不相同的症状。神经外科医生参与测试，并对IEMAS的实用性进行了研究。我们分析了测试持续时间以及外科医生与检查者之间的信息交换次数。
使用IEMAS时的总测试持续时间明显短于未使用IEMAS时（116.1±23.1秒对147.8±48.7秒；P<0.02）。使用IEMAS时外科医生与检查者之间的信息交换次数明显低于未使用IEMAS时（0.2±0.6次对16.1±15.6次；P<0.02）。
我们比较了使用和未使用IEMAS的病例。使用IEMAS时总测试持续时间缩短，信息交换次数减少，从而证明了IEMAS的实用性。
