The lower threshold of hypothermic oxygen delivery to prevent neonatal acute kidney injury

CONCLUSIONS: The importance of hypothermic DO2i should be highlighted, even when SvO2 was satisfactory. A lower threshold of DO2i > 269 mL min-1 m-2 may help protect neonates from the risk of postoperative AKI.IMPACT: The key message of our article is that the lower threshold of DO2i > 269 mL min-1 m-2 may help protect neonates from the risk of AKI after on-pump hypothermic cardiovascular surgery. The critical DO2i value for neonates undergoing hypothermic CPB remains unclear, and our study may add new evidence for this matter based on the 6-year experience of our center. In this study, the lowest critical value of DO2i in neonatal hypothermic CPB is determined for the first time, which provides a reference for intra-CPB management strategy to improve the postoperative outcomes of newborns.PMID:34274961 | DOI:10.1038/s41390-021-01654-9
