In this study, we evaluated the effect of mild hypothermic CPB strategy on cerebral oximetry near-infrared spectroscopy in congenital heart defects surgery. Methods: In a randomized prospective study, the pediatrics aged two months and six years with RACHS categories I-Ⅱ for congenital heart defects surgery were randomly divided into normothermic and mild hypothermic CPB groups. The NIRS was measured in all patients via the INVOS ™ cerebral oximetry system. The perfusion and anesthesia strategies during the study were followed as standard methods. A p-value below 0.05 is considered to be a significant level. Results: Regarding cerebral oximetry, the results showed no significant difference between normothermic and mild hypothermic CPB groups. Conclusion: It can be concluded that optimizing cerebral oxygen saturation monitoring during congenital cardiac surgery can improve patient outcomes as a protective strategy. https://aacc.tums.ac.ir/index.php/aacc/article/view/961
