“…According to the present and previous studies, SjvO 2 demonstrated the cerebral desaturation during CPB in 54% of patients in a normothermic group and 12% of those in a hypothermic group (27°C). 6 If cerebral desaturation is related to postoperative neurological disorders, as suggested by Croughwell et al , 10 mild hypothermia is superior to normothermia in preventing postoperative neurological disorders.…”

“…4 In addition, SjO 2 50% during rewarming is associated with impaired cognitive function after CPB surgery. 2 The unique ability of light in the near infrared range (700-1300 nm) to detect the oxygenation of living tissues was first described by Jobsis in 1977. 5 Since that time, NIRS has emerged as a promising in vivo technique and as a continuous cerebral oxygenation monitor during cardiac surgery.…”

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.

“…There are few studies, mostly retrospective and with limited sample size, especially in children, correlating SjO 2 and SvO 2 during heart surgery with CPB [1][2][3]8,[9][10][11]. Similar to adults, discrepancies between the two variables are consistently observed.…”

“…Normal values are between 55% -75%, which are always smaller than the simultaneous SvO 2 . It is a global measure, and it may not reflect hypoperfusion (focal ischemia), therefore, normal or lower values do not necessarily ensure adequate oxygenation, on the other hand, low values (<50-54%) indicate focal or global ischemia severe enough to cause low SjO 2 , associated with postoperative neurological deficits [1][2][3]8,9].…”
