摘要

电阻抗断层扫描的动态区域准确性尚未得到验证。我们旨在比较动态通气期间电阻抗断层扫描与四维计算机断层扫描的区域准确性。这项在普通重症监护病房进行的单中心、前瞻性观察研究纳入了 2021 年 7 月至 2024 年 2 月期间接受机械通气的成年患者。患者接受被动机械通气,并在同一天接受电阻抗断层扫描和四维计算机断层扫描。共对 45 名患者进行了分析。四维计算机断层扫描和电阻抗断层扫描在各区域动态通气的相关系数分别为:右肺 0.963、0.963、0.835(腹侧、中央和背侧),左肺 0.947、0.927、0.823(腹侧、中央和背侧)。当电阻抗断层扫描检测到的区域通气分布小于 2% 时,相关系数较低。排除区域通气分布小于 2% 的 9 名患者后,右肺的腹侧、中央和背侧相关系数分别为 0.963、0.963 和 0.946,左肺的相关系数分别为 0.942、0.924 和 0.951。与四维计算机断层扫描相比,使用电阻抗断层扫描进行动态通气时的区域通气非常准确,且与时间相一致。鉴于这些模式之间的高度相关性,它们可为进一步研究区域通气动态做出重大贡献。试验注册号:ClinicalTrials.gov(编号:UMIN00044386)。

Regional ventilation dynamics of electrical impedance tomography validated with four-dimensional computed tomography: single-center, prospective, observational study
The dynamic regional accuracy of electrical impedance tomography has not yet been validated. We aimed to compare the regional accuracy of electrical impedance tomography with that of four-dimensional computed tomography during dynamic ventilation. This single-center, prospective, observational study conducted in a general intensive care unit included adult patients receiving mechanical ventilation from July 2021 to February 2024. The patients were mechanically ventilated passively and underwent electrical impedance tomography and four-dimensional computed tomography on the same day. Overall, 45 patients were analyzed. The correlation coefficients in regional dynamic ventilation between four-dimensional computed tomography and electrical impedance tomography in each region were 0.963, 0.963, 0.835 (ventral, central, and dorsal, respectively) in the right lung and 0.947, 0.927, 0.823 (ventral, central, and dorsal, respectively) in the left lung. The correlation coefficient was low when the regional ventilation distribution detected by the electrical impedance tomography was < 2%. After excluding nine patients with a regional ventilation distribution of < 2%, the ventral, central, and dorsal correlation coefficients were 0.963, 0.963, and 0.946 in the right lung and 0.942, 0.924, and 0.951, respectively, in the left lung. Regional ventilation using electrical impedance tomography during dynamic ventilation was highly accurate and consistent with the time phase compared to four-dimensional computed tomography. Given the high correlation between these modalities, they can contribute significantly to further studies on regional ventilation dynamics.

期刊介绍: Critical Care is an esteemed international medical journal that undergoes a rigorous peer-review process to maintain its high quality standards. Its primary objective is to enhance the healthcare services offered to critically ill patients. To achieve this, the journal focuses on gathering, exchanging, disseminating, and endorsing evidence-based information that is highly relevant to intensivists. By doing so, Critical Care seeks to provide a thorough and inclusive examination of the intensive care field.
