“…AUC-ROC analysis for renal rSO 2 values < 55% for >1.5 min showed a sensitivity of 64.7% and a specificity of 88.5% (AUC = 0.777, 95% CI: 0.669–0.885; p < 0.001) for predicting CSA-AKI. Nonetheless, the usefulness of renal rSO 2 measurements in detecting CSA-AKI could not be confirmed in other investigations [ 65 , 66 ], and two studies even suggested that low renal rSO 2 values before and during CPB may have kidney-protective effects [ 47 , 66 ]. In a small prospective cohort study of 66 infants (≤10 kg) undergoing CHD repair with CPB, infants with lower baseline and i.o.…”

Traditional renal biomarkers such as serum creatinine and albuminuria/proteinuria are rather insensitive since they change later in the course of the disease. In order to determine the extent and type of kidney injury, as well as to administer the proper therapy and enhance patient management, new techniques for the detection of deterioration of the kidney function are urgently needed. Infrared spectroscopy is a label-free and non-destructive technique having the potential to be a vital tool for quick and inexpensive routine clinical diagnosis of kidney disorders. The aim of this review is to provide an overview of near- and mid-infrared spectroscopy applications in patients with acute kidney injury and chronic kidney disease (e.g., diabetic nephropathy and glomerulonephritis).

“…The evidence regarding clinical utility in these circumstances is equivocal. [8][9][10] There are only limited reports of the use of NIRS during EVT, all including patients with an internal carotid artery (ICA) or middle cerebral artery (MCA) occlusion. [11][12][13][14] These studies show conflicting outcomes, which might be due to application of the NIRS 'sensor' (i.e.…”

Introduction: The aim of endovascular treatment (EVT) for acute ischaemic stroke is to relieve the cerebral tissue hypoxia in the area supplied by the occluded artery. Near-infrared spectroscopy (NIRS) monitoring is developed to assess regional cerebral tissue oxygen haemoglobin saturation (rSO2). We aimed to investigate whether NIRS can detect inter- and intra-hemispheric rSO2 differences during EVT. Patients and methods: In this prospective, observational study, patients undergoing EVT for a proximal intracranial occlusion of the anterior circulation between May 2019 and November 2020, were included. A four-wavelength NIRS monitor (O3® Regional Oximeter (Masimo, Irvine, CA)) was used to measure rSO2 during EVT with sensors placed over the temporal lobes in 20 patients and over the frontal lobes in 13 patients. The Wilcoxon signed-rank test was used to test for inter-hemispheric rSO2 differences after groin puncture and after recanalisation, and intra-hemispheric rSO2 changes before and after recanalisation. Results: In the temporal cohort, no inter-hemispheric rSO2 differences were observed after groin puncture (median [IQR] rSO2 affected hemisphere, 70% [67–73] and unaffected hemisphere, 70% [66–72]; p = 0.79) and after recanalisation. There were no intra-hemispheric rSO2 changes over time. In the frontal cohort, no inter- and intra-hemispheric rSO2 differences or changes were found. Discussion and conclusion: A NIRS monitor could not detect inter- and intra-hemispheric rSO2 differences or changes during EVT, irrespective of the sensor position. It is likely that even with temporal sensor application, a significant proportion of the received NIRS signal was influenced by oxygenation of surrounding tissues.

“…Yet, the evidence supporting its use in the adult population is limited. In patients undergoing cardiac surgery with cardiopulmonary bypass, renal tissue oxygen saturation had an acceptable agreement with renal vein saturation [7], but conflicting results were found regarding the association of renal region desaturation with postoperative renal injury [16,17]. One point of concern is that the penetration depth of the sensors might be insufficient to reach the kidney in adults.…”

Purpose: O3® Regional Oximetry (Masimo Corporation, California, USA) is validated for cerebral oximetry. We aimed to assess agreement of somatic and renal near-infrared spectroscopy with reference blood samples. Methods: O3 sensors were placed bilaterally on the quadriceps and flank of 26 healthy volunteers. A stepped, controlled hypoxia sequence was performed by adding a mixture of nitrogen and room air to the breathing circuit. O3-derived oxygen saturation values were obtained at baseline and at six decremental saturation levels (5% steps). Blood samples (radial artery, iliac vein (somatic reference) and renal vein) were obtained at each step. Reference values were calculated as: 0.7 × venous saturation + 0.3 × arterial saturation. The agreement between O3-derived values with blood reference values was assessed by calculating root-mean-square error accuracy and Bland-Altman plots. Results: The root-mean-square error accuracy was 6.0% between quadriceps oxygen saturation and somatic reference values. The mean bias was 0.8%, with limits of agreement from -7.7 to 9.3%. These were 5.1% and 0.6% (-8.3 to 9.5%) for flank oxygen saturation and somatic reference values, respectively, and 7.7% and -4.9% (-15.0 to 5.2%) for flank oxygen saturation and renal reference values. The kidney depth was 3.1 ± 0.9 cm below the skin. Conclusion: O3 regional oximetry can be used on the quadriceps and flank to monitor somatic saturation, yet has a saturation-level dependent bias. O3-derived values obtained at the flank underestimated renal reference values. Additionally, it is unlikely that the flank sensors did directly measure renal tissue.
