Abstract:

Under the action of various etiologies such as fluid loss, infection and immune diseases, the renal tissue is prone to hypoxia and ischemia, resulting in acute kidney injury (AKI) due to its relatively weak autonomic regulation ability. The incidence of AKI is high, which seriously affects the prognosis of critically ill children, but there is a lack of clinically applicable early diagnosis indicators. In recent years, the application of near infrared reflectance spectroscopy (NIRS) to monitor renal oxygen saturation (RrSO2) can reflect renal blood perfusion and indirectly reflect renal function. Based on the research progress of RrSO2 at home and abroad, this paper summarized the clinical application of NIRS in kidney, and proposed that RrSO2 could be used as a powerful indicator for clinical diagnosis of AKI.

Key words: acute kidney injury, near infrared reflectance spectroscopy, renal oxygen saturation
