Abstract

Background: Prolonged electroencephalographic depression during surgery is associated with poor outcomes for patients. However, the published literature on electroencephalographic depression caused by a sudden increase in the partial pressure of end-tidal carbon dioxide (PETCO2) is lacking.

Case presentation: We report four patients who were scheduled for laparoscopic liver surgery under general anesthesia. During the process of EEG monitoring with Sedline, four patients experienced electroencephalographic depression closely after a sudden increase in PETCO2. The four patients showed that electroencephalographic depression mainly manifested as a slow in EEG frequency, a reduction in the amplitude and power of EEG, and a decrease in spectral edge frequency. Patient state index was elevated in three cases.

Conclusions: To summarize, our patients showed EEG depression when PETCO2 suddenly increased, which suggests that clinical doctors should be alert to electroencephalographic depression when the PETCO2 abruptly increases. EEG monitoring devices should be applied in patients with possible hypercapnia. Anesthesiologists must comprehensively interpret the raw EEG, spectral edge frequency, and density spectral array data, in addition to patient sedation index values.

突然增加潮气末二氧化碳分压后的脑电图抑制:一个病例系列。
背景:手术期间长时间的脑电抑制与患者的不良预后有关。然而,关于潮气末二氧化碳分压(PETCO2)突然升高导致的脑电抑制的文献尚缺:我们报告了四例计划在全身麻醉下进行腹腔镜肝脏手术的患者。在使用 Sedline 进行脑电图监测的过程中,四名患者在 PETCO2 突然升高后紧接着出现了脑电抑制。四名患者的脑电抑制主要表现为脑电图频率减慢、脑电图振幅和功率减小、频谱边缘频率降低。3例患者的状态指数升高:综上所述,我们的患者在 PETCO2 突然升高时出现脑电图抑制,这提示临床医生应警惕 PETCO2 突然升高时出现的脑电图抑制。对于可能出现高碳酸血症的患者,应使用脑电图监测设备。麻醉医生必须全面解读原始脑电图、频谱边缘频率和密度谱阵列数据,以及患者镇静指数值。
