区域组织灌注指数(RTPI):一种新的基于光学的量化区域组织灌注的指标。
准确、连续地评估局部组织灌注仍然是一个重大的临床挑战,因为大多数现有的模式是侵入性的、间接的,或者不适合常规监测。近红外光谱(NIRS)已被广泛用于评估组织氧合;然而,传统的nirs衍生指标不足以替代真实灌注,并且往往无法捕捉快速的血流动力学变化。本研究旨在引入和验证区域组织灌注指数(RTPI),这是一种新的NIRS衍生指标,整合了NIRS信号的多个特征,提供连续、无创和生理相关的组织灌注评估。RTPI是利用nirs衍生的多个参数(包括脉冲幅度比、导数和曲线下面积)的主成分分析(PCA)得出的。在健康志愿者的受控缺血再灌注方案中评估其性能,并与建立的参考标准进行比较,包括激光多普勒血流测定(LDF)和光电体积脉搏波描记(PPG)。动态灌注变化时,RTPI与LDF Flux和PPG灌注指数(PI)有良好的相关性。与传统的nirs衍生的氧合和血流动力学指标不同,RTPI在分析的数据集中对完全和部分缺血再灌注发作都表现出即时和显著的敏感性。类内相关性表明RTPI的会话对会话的可靠性高于Flux和PI。RTPI是一种多参数、生理上有意义、计算效率高的组织灌注实时监测指标。它独立于氧合指数检测灌注损害的能力突出了其在重症监护、创伤、围手术期和血管医学的床边应用的转化潜力,在这些领域,提高诊断准确性可以显著影响患者的预后。

期刊介绍: The Journal of Clinical Monitoring and Computing is a clinical journal publishing papers related to technology in the fields of anaesthesia, intensive care medicine, emergency medicine, and peri-operative medicine. The journal has links with numerous specialist societies, including editorial board representatives from the European Society for Computing and Technology in Anaesthesia and Intensive Care (ESCTAIC), the Society for Technology in Anesthesia (STA), the Society for Complex Acute Illness (SCAI) and the NAVAt (NAVigating towards your Anaestheisa Targets) group. The journal publishes original papers, narrative and systematic reviews, technological notes, letters to the editor, editorial or commentary papers, and policy statements or guidelines from national or international societies. The journal encourages debate on published papers and technology, including letters commenting on previous publications or technological concerns. The journal occasionally publishes special issues with technological or clinical themes, or reports and abstracts from scientificmeetings. Special issues proposals should be sent to the Editor-in-Chief. Specific details of types of papers, and the clinical and technological content of papers considered within scope can be found in instructions for authors.
