IntroductionTissue oxygen saturation (StO2) and the vascular occlusion test (VOT) can identify tissue hypoperfusion in trauma and sepsis. However, the technique is neither standardized nor uses the same monitoring site. We hypothesized that baseline and VOT StO2 would be different in the forearm (F) and thenar eminence (TH) and that different minimal StO2 values during the VOT would result in different reoxygenation rates (ReO2).MethodsStO2 and its change during the VOT were simultaneously measured in the F and TH, with 15 mm and 25 mm probes, using the 325 InSpectra monitor in 18 healthy, adult volunteers. Two VOTs were done to a threshold thenar StO2 of 40% interchanging the 15 mm and 25 mm probes between sites. Two additional VOTs were done to thresholds of 50% and 30%. Baseline StO2 (BaseO2), the deoxygenation rate (DeO2) and ReO2 were compared between sites, probes and (%O2/minute) thresholds. Results are presented as the median (interquartile range), P-value.ResultsBaseO2, DeO2, ReO2, area under the curve and hyperemia duration values were different when comparing TH vs. F and 15 mm vs. 25 mm probes. ReO2 was different between different thresholds for the TH and 15 mm probes. TH15 mm vs. F15 mm: BaseO2, 90.4 (85.2, 93.5) vs. 85.2 (80.7, 90.2), P = 0.031; DO2, -12.1 (-16.2, -11.3) vs. -8.5 (-10.3, -7.8), P = 0.011; ReO2, 297.2 (213.7, 328.6), P < 0.0001; 15 mm vs. 25 mm probe: BaseO2, 97.2 (89.4, 94.7) vs. 87.3 (81.7, 90.9), P = 0.016; DeO2, -18.0 (-24.1, -14.8) vs. -9.9 (-15.3, -6.5), P < 0.0001; and ReO2, 401.6 (331.7, 543.2) vs. 160.5 (132.3, 366.9), P = 0.012, respectively. TH15 mm vs. TH25 mm: BaseO2, P = 0.020; DeO2, P < 0.0001; and ReO2, P < 0.0001. Threshold StO2 values (15 mm probe only): ReO2, P = 0.003; DeO2, P = 0.60. ReO2 at 40% and 50% StO2 thresholds, P = 0.01.ConclusionsBaseO2, DeO2 and ReO2 were different when measured in different anatomical sites (F and TH) and with different probe sizes, and ReO2 was different with differing VOT release StO2 threshold values. Thus, standardization of the site, probe and VOT challenge need to be stipulated when reporting data.
. This report is the second part of a comprehensive two-part series aimed at reviewing an extensive and diverse toolkit of novel methods to explore brain health and function. While the first report focused on neurophotonic tools mostly applicable to animal studies, here, we highlight optical spectroscopy and imaging methods relevant to noninvasive human brain studies. We outline current state-of-the-art technologies and software advances, explore the most recent impact of these technologies on neuroscience and clinical applications, identify the areas where innovation is needed, and provide an outlook for the future directions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
