Abstract

Three Doppler-derived techniques have been proposed to assess renal perfusion at bedside: Doppler-based renal resistive index (RI) which has been extensively but imperfectly studied in assessing renal allograft status and changes in renal perfusion in critically ill patients and for predicting the reversibility of an acute kidney injury (AKI), semi-quantitative evaluation of renal perfusion using colour-Doppler which may be easier to perform and may give similar information than RI and contrast-enhanced sonography that may allow more precise renal and cortical perfusion assessment. These promising tools have several obvious advantages including their feasibility, non-invasiveness, repeatability and potential interest in assessing renal function or perfusion. However, several limits need to be taken into account with these techniques, and promising results remain associated with large areas of uncertainty. This editorial will describe more carefully advantages and limits of these techniques and will discuss their potential interest in assessing renal perfusion.

床边多普勒超声评估ICU肾灌注:现有技术的优点和局限性。
提出了三种多普勒衍生技术来评估床边的肾脏灌注:基于多普勒的肾抵抗指数(RI)在评估异体肾移植状态和危重患者肾灌注变化以及预测急性肾损伤(AKI)的可逆性方面得到了广泛但不完善的研究,使用彩色多普勒对肾灌注进行半定量评估可能更容易执行,并且可能比RI和对比增强超声提供类似的信息,后者可能允许更精确的肾脏和皮质灌注评估。这些有前途的工具有几个明显的优点,包括它们的可行性、无创性、可重复性和评估肾功能或灌注的潜在兴趣。然而,这些技术需要考虑到一些限制,并且有希望的结果仍然与很大的不确定性领域有关。这篇社论将更仔细地描述这些技术的优点和局限性,并讨论它们在评估肾灌注方面的潜在兴趣。
