“…rcSO 2 was increased with a mean delay of 13.4 sec, whereas the increase of SpO 2 featured a significant delay of 18.9 sec. These results are similar to those of previous studies (9,11). It is well known that the brain responds to hypoxia through increasing cerebral blood flow.…”

“…A previous study revealed that with SpO 2 maintained in the normal range, a decrease of >20% may be observed in cerebral oxygen saturation (17). Another study indicated that SpO 2 readings were 10-15 sec delayed compared with rcSO 2 readings in neonates (9). Similar results were also reported by Tanidir et al (18).…”

“…Therefore, rcSO 2 does not provide an indicator of oxygen delivery and instead provides information regarding the balance between regional oxygen supply and demand (4). Recent studies have suggested that pediatric patients may benefit from rcSO 2 monitoring during surgery (5)(6)(7)(8)(9). The use of rcSO 2 is increasing, but the routine use of rcSO 2 as a standard-of-care monitor is still not recommended at present.…”

Pulse oximetry and measurement of regional cerebral oxygen saturation (rcSO 2) are used to monitor peripheral and cerebral oxygenation, respectively. However, the response of rcSO 2 and pulse oxygen saturation (SpO 2) to hypoxia in preschool children has not been previously assessed. A total of 36 preschool patients who had undergone a tonsillectomy [age, 4-6 years, American Society of Anesthesiologists grade I or II] were screened and prospectively enrolled in the present study. Hemodynamics, including rcSO 2 , SpO 2 , non-invasive blood pressure, heart rate, electrocardiogram and capnography, were continuously monitored throughout the study. Following pre-oxygenation, pressure-controlled ventilation with 100% oxygen was administered through a mask with a flow rate of 6 l/min, under total intravenous anesthesia, and the end-tidal carbon dioxide partial pressure was maintained between 30 and 40 mmHg. Tracheal intubation was then performed and ventilation was paused until SpO 2 decreased to 90% or rcSO 2 decreased by >10% of the baseline level. The duration from pausing of mechanical ventilation to the start of the rcSO 2 decline was shorter than that of SpO 2 (80.2±23.6 sec vs. 124.4±20.5 sec; P<0.001). Subsequent to the recovery of ventilation, the duration from the starting point to the increasing point of the baseline of rcSO 2 was longer than that of SpO 2 (84.8±24.3 sec vs. 15.2±6.8 sec; P<0.001). From the point where mechanical ventilation was paused to when rcSO 2 /SpO 2 began to decrease, the rcSO 2 and SpO 2 values decreased and a significant correlation of them was observed (Pearson's correlation coefficient=0.317; P=0.027). From the time-point where mechanical ventilation was recovered to the time-point where rcSO 2 or SpO 2 began to increase, rcSO 2 and SpO 2 values decreased and a significant correlation of them was observed (Spearman's correlation coefficient= 0.489; P= 0.006). From the baseline to the minimum value, compared with the SpO 2 , the rcSO 2 declined at a decreased rate (9.7±0.5% vs. 5.3±2.7%; P<0.001). The present clinical trial was registered at http://www.chictr.org.cn on 14th March 2016 (registration no. ChiCTR-OOC-16008095).

“…Previous studies have demonstrated that cerebral oxygenation monitoring using near-infrared spectroscopy (NIRS) can detect alterations in oxygenation earlier than pulse oximetry. 25 – 29 NIRS is a noninvasive optical technology used to measure tissue oxygenation and hemodynamics in various tissues, such as the brain, skeletal muscle, and spinal cord. 30 – 33 Using similar physics principles to pulse oximetry, NIRS generates NIR light signals that penetrate tissue and measure the amount of light absorbed by tissue chromophores.…”

“…To our knowledge, there are no reports to date comparing transcutaneous NIRS monitoring to pulse oximetry during acute hypoxia, as previous comparative studies focused on cerebral NIRS measurements. 25 – 29 Transcutaneous NIRS monitoring of tissue hypoxia provides a better alternative to cerebral NIRS monitoring as it uses a simple and small sensor that can be easily placed on any part of the body over the skin. Cerebral NIRS systems require a large sensor with a 3- to 4-cm interoptode distance (IOD) because a higher depth of penetration is needed to access the brain cortex, whereas a transcutaneous NIRS system can use a smaller sensor with a 1-cm IOD.…”

. Significance : Pulse oximetry is widely used in clinical practice to monitor changes in arterial oxygen saturation ( ). However, decreases in can be delayed relative to the actual clinical event, and near-infrared spectroscopy (NIRS) may detect alterations in oxygenation earlier than pulse oximetry, as shown in previous cerebral oxygenation monitoring studies. Aim : We aim to compare the response of transcutaneous muscle NIRS measures of the tissue saturation index with pulse oximetry during hypoxia. Approach : Episodes of acute hypoxia were induced in nine anesthetized Yucatan miniature pigs. A standard pulse oximeter was attached to the ear of the animal, and a transcutaneous NIRS sensor was placed on the hind limb muscle. Hypoxia was induced by detaching the ventilator from the animal and reattaching it once the pulse oximeter reported 70% . Results : Twenty-four episodes of acute hypoxia were analyzed. Upon the start of hypoxia, the transcutaneous NIRS measures changed in , whereas the pulse oximetry measures changed in ( ). Conclusions : Transcutaneous muscle NIRS can detect the effects of hypoxia significantly sooner than pulse oximetry in the Yucatan miniature pig. A transcutaneous NIRS sensor may be used as an earlier detector of oxygen saturation changes in the clinical setting than the standard pulse oximeter.
