“…In children, Dullenkopf et al 5 observed significantly lower TOI values (measured with the NIRO 300) compared to rSO2 values (measured with the INVOS 5100) and described a very large range in cerebral oxygenation values in children (rSO2: 59-95%; TOI: 48-85%). These results are consistent with our cerebral measurements in neonates.…”

“…By comparing the adult and the pediatric sensor of INVOS 5100, Dullenkopf et al 5 observed also a difference of 10%, whereby the neonatal sensor, which is recommended in neonates, was not analyzed and compared until now.…”

“…2 Most studies in neonates were done with either the NIRO (Hamamatsu R , Japan) 3 or the INVOS (Somanetics R , USA) 4 or both. 5,6 The comparison of studies using these different devices remains difficult. 7 These devices have already been compared in regard to cerebral oxygenation 8 and the interpretation of different results remains very difficult too.…”

Abstract. Comparability and reproducibility of different near-infrared spectroscopy devices measuring regional tissue oxygen saturation remain poor. Aim of the present study was to compare values and reproducibility of cerebral/peripheral "tissue-oxygenation-index" (TOI; NIRO 300, Hamamatsu R , Japan) with cerebral/peripheral "regional-oxygen-saturation" (rSO; INVOS5100, Somanetics R , USA), and to analyze the influence of quality criteria. Methods: cTOI and crSO2 were measured on the left forehead, pTOI and prSO2 were measured on the left calf. To analyse reproducibility, optodes were reapplied five times. A quality criterion was introduced for cTOI, crSO2 and prSO2. For pTOI quality criteria were introduced in combination with a venous occlusion technique. Results: Cerebral measurements were performed in 37 neonates. cTOI (72.7 + / − 6.2%) was lower than crSO2 (83.3 + / − 5.8%) (p < 0.001). The mean difference between cTOI and crSO2 was 10%. Mean standard deviations of cTOI and crSO2 were similar (cTOI: 4.9 + / − 3.6; crSO2: 4.5 + / − 2.6). Peripheral measurements were performed in 39 neonates. pTOI (66.0 + / − 7.9%) was lower than prSO2 (82.0 + / − 7.0%)(p < 0.001). The mean difference between pTOI and prSO2 was 15%. Mean standard deviations of pTOI (3.7 + / − 2.6%) were lower than of prSO2 (5.0 + / − 3.0%) (p = 0.047). Conclusion: TOI values were significantly lower than rSO2 values, in cerebral and peripheral measurements. Reproducibility was higher for pTOI than for prSO2.

“…Many of the previous clinical studies comparing devices have the drawback of rather narrow oxygenation range. For instance the NIRO 300 and INVOS 4100/5100 adult sensor have been compared several times showing comparable mean values during steady state, but all studies had very few if any rStO 2 values below 50% [38][39][40][41]. Regarding the difference between the INVOS adult and pediatric sensors, Dullenkopf et al found a similar mean difference of 11.3 ± 5.37% (SD) between the two sensors, while Pocivalnik found a mean difference of 10% between the NIRO 300 and the INVOS neonatal sensor [42], that has been shown to give similar values to the paediatric sensor [43].…”

Abstract:In a blood-lipid liquid phantom the prototype near-infrared spectroscopy oximeter OxyPrem was calibrated against the INVOS® 5100c adult sensor in respect to values of regional tissue oxygen haemoglobin saturation (rStO 2 ) for possible inclusion in the randomised clinical trialSafeBoosC. In addition different commercial NIRS oximeters were compared on changing haemoglobin oxygen saturation and compared against co-oximetry. The best calibration was achieved with a simple offset and a linear scaling of the OxyPrem rStO 2 values. The INVOS adult and pediatric sensor gave systematically different values, while the difference between the NIRO® 300 and the two INVOS sensors were magnitude dependent. The co-oximetry proved unreliable on such low haemoglobin and high Intralipid levels. 34. W. G. Zijlstra, A. Buursma, and W. P.

Cerebral oximetry in preterm infants: an agenda for research with a clear clinical goal

et al. 2016

Abstract. Preterm birth constitutes a major cause of death before 5 years of age and it is a major cause of neurodevelopmental impairment across the world. Preterm infants are most unstable during the transition between fetal and newborn life during the first days of life and most brain damage occurs in this period. The brain of the preterm infant is accessible for tissue oximetry by near-infrared spectroscopy. Cerebral oximetry has the potential to improve the long-term outcome by helping to tailor the support of respiration and circulation to the individual infant's needs, but the evidence is still lacking. The goals for research include testing the benefit and harms of cerebral oximetry in large-scale randomized trials, improved definition of the hypoxic threshold, better understanding the effects of intensive care on cerebral oxygenation, as well as improved precision of oximeters and calibration among devices or standardization of values in the hypoxic range. These goals can be pursued in parallel. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
