“…Daubeney et al 16 studied 29 children undergoing cardiac catheterization and 11 children during cardiac surgery. They found a significant correlation between the individual measurements (n=147) of the two methods (r2=0.476, P <0.0001) but the authors did not perform a Bland and Altman analysis.…”

Spatially troscopy does not resolved spec-(NIRO-300) agree with jugular bulb oxygen saturation in patients undergoing warm bypass surgery Purpose: Near infrared spectroscopy (NIRS) is a promising noninvasive method for continuous monitoring of cerebral oxygenation during cardiac surgery with cardiopulmonary bypass (CPB). This study was designed to study the agreement between tissue oxygen index (TO o measured by spatially resolved spectroscopy (NIRO-300) and jugular bulb oxygen saturation (SjO2) in patients undergoing warm coronary bypass surgery.Methods: Seventeen patients undergoing warm coronary artery bypass surgery were studied. NIRS was continuously monitored and was averaged before CPB, five, 20, 40, 60 min on CPB, five minutes before end of CPB and ten minutes after CPB to coincide with SjO 2 measurements. Bypass temperature was maintained at 34-37°C.Results: Bland and Altman analysis showed a bias (TOI-SjO2) of-6.7%, and wide limits of agreement (from 16% to -28%) between the two methods. In addition, mean TOI was lower than mean SjO~ during and after CPB. We observed a statistically significant correlation between arterial carbon dioxide and SjO 2 measurements (r 2 0.33; P 0.0003), but the former did not correlate with TOI values (r 2 0.001; P 0.7).Conclusion: Our results demonstrate a lack of agreement between SjO 2 and TOI for monitoring cerebral oxygenation during cardiac surgery. We conclude that the two methods are not interchangeable.

“…[41][42][43][44] The relationship and correlation of cerebral NIRS to this modality (inside and outside the context of TBI) has been reported, with positive results in multiple small observational investigations in children. [45][46][47] As such, evidence for how changes in cerebral NIRS parameters reflect and predict changes in jugular bulb oximetry is sparse, particularly within the context of TBI.…”

Cerebral near-infrared spectroscopy (NIRS) has long represented an exciting prospect for the noninvasive monitoring of cerebral tissue oxygenation and perfusion in the context of traumatic brain injury (TBI), although uncertainty still exists regarding the reliability of this technology specifically within this field. We have undertaken a review of the existing literature relating to the application of NIRS within TBI. We discuss current ''state-of-the-art'' NIRS monitoring, provide a brief background of the technology, and discuss the evidence regarding the ability of NIRS to substitute for established invasive monitoring in TBI.

“…Hypercapnoea (PaCO 2 > 50 mmHg) is frequently encountered during equine general anaesthesia, predominantly due to the respiratory depression and subsequent hypoventilation caused by inhalation agents used for maintenance 86 will differ slightly compared to those reported at 37°C, as was observed in the current study ( 89,92 . Attempts to recreate this method were made in the present study by catheterising the external jugular vein in a retrograde manner, in order to sample venous blood from as close to the brain as possible.…”

“…Secondly, the subtraction algorithm used by the cerebral oximeter to calculate rSO 2 was designed for human patients and is based on the assumption that 75% of cerebral blood flow is venous 8,89 . In the present study the sensor was placed over the region of the DSS through which venous blood flow is greater than 75%, potentially invalidating the algorithm.…”

Summary Reasons for performing study Alterations in cerebral haemodynamics may contribute to perianaesthetic complications in horses. Near‐infrared spectroscopy (NIRS) is frequently used intraoperatively in man to provide information regarding cerebral perfusion. Objectives To determine whether NIRS can identify trends in regional cerebral oxygen saturation (rSO2) in horses and whether there is a correlation between rSO2 and venous oxygen tensions. Methods A cerebral oximeter sensor recorded rSO2 from the dorsal sagittal sinus of 6 healthy horses. Values for rSO2, arterial and venous oxygen and carbon dioxide tensions (PaO2, PvO2, PaCO2 and PvCO2 respectively), along with arteriovenous oxygen saturations (SavO2) were recorded in unsedated (recording period [RP] 1), sedated (RP2) and anaesthetised horses (RP3–5) and during recovery (RP6–8). During anaesthesia, horses were ventilated to achieve states of normo‐ (RP3), hyper‐ (RP4) and hypocapnoea (RP5). Data were evaluated descriptively and analysed using linear mixed‐effects models and Pearson's correlation coefficient. Results Overall mean ± s.d. values for rSO2, PaO2, PvO2, PaCO2, SavO2 and mean arterial pressure varied significantly by RP (P<0.001). Significant decreases in rSO2 were identified between RP1 and the post anaesthetic periods (P<0.001). No significant differences in rSO2 values were identified between RP1 and the intra‐anaesthesia periods or between RP3, RP4 and RP5. Significant correlations were identified between rSO2 and PaO2 (r = 0.448, P<0.001), rSO2 and PvO2 (r = 0.512, P<0.001) and rSO2 and SavO2 (r = 0.469, P<0.001). Conclusions This is the first study to identify trends in rSO2 in horses using NIRS. A positive correlation was identified between rSO2 and PvO2, suggesting that alterations in cerebral oxygenation may be reflected in PvO2. Potential relevance Near‐infrared spectroscopy may be used to monitor trends in rSO2 during equine anaesthesia. Decreasing rSO2 values may act as an early warning signal, alerting clinicians to potential cerebral desaturation events and indicating a need for intervention.
