Abstract
Accurate stroke volume (SV) assessment is crucial in ischaemic cardiogenic shock. While pulmonary artery catheterisation remains the gold standard, its invasive nature necessitates reliable noninvasive alternatives. However, the literature on echocardiographic SV accuracy is inconsistent. This study evaluated commonly used echocardiographic techniques-Doppler-derived and Simpson's method-against invasive thermodilution in 39 patients. SV by Doppler showed strong correlation (r = 0.91, p < 0.0001) and minimal bias, whereas the Simpson's method exhibited weaker correlation and more significant underestimation. These findings suggest Doppler echocardiography as the more accurate noninvasive tool for SV estimation, addressing prior discrepancies and enhancing haemodynamic management in critical care.
准确的脑卒中容量（SV）评估是缺血性心源性休克的关键。虽然肺动脉插管仍然是金标准，但其侵入性需要可靠的非侵入性替代方案。然而，关于超声心动图SV准确性的文献并不一致。本研究评估了39例患者常用的超声心动图技术——多普勒衍生法和辛普森法——对侵入性热稀释的影响。多普勒超声显示SV有很强的相关性(r = 0.91, p
期刊介绍：
The Journal of the Intensive Care Society (JICS) is an international, peer-reviewed journal that strives to disseminate clinically and scientifically relevant peer-reviewed research, evaluation, experience and opinion to all staff working in the field of intensive care medicine. Our aim is to inform clinicians on the provision of best practice and provide direction for innovative scientific research in what is one of the broadest and most multi-disciplinary healthcare specialties. While original articles and systematic reviews lie at the heart of the Journal, we also value and recognise the need for opinion articles, case reports and correspondence to guide clinically and scientifically important areas in which conclusive evidence is lacking. The style of the Journal is based on its founding mission statement to ‘instruct, inform and entertain by encompassing the best aspects of both tabloid and broadsheet''.
