Necrotizing enterocolitis(NEC)is one of the most common gastrointestinal diseases in neonatal intensive care units,characterized by rapid progression and a high mortality rate.Local intestinal ischemia and hypoxia are significant contributors to NEC.Feeding intolerance(FI),which refers to a range of gastrointestinal manifestations arising from the inability to tolerate enteral nutrition,is one of the most common clinical issues in neonates,and preventing and treating FI is crucial for improving neonatal survival rates.Near-infrared spectroscopy is a clinical tool that can be used at the bedside to monitor regional oxygen saturation.It is non-invasive,reliable,and sustainable,and its feasibility and safety in assessing intestinal blood circulation have been validated.Early identification of intestinal ischemia and differentiation of FI from precursor symptoms of NEC,as well as predicting the occurrence of NEC,are extremely important for reducing intestinal injury and adverse long-term outcomes.In recent years,there has been new research progress related to the monitoring of intestinal tissue oxygen saturation and cerebral oxygen saturation for the early identification of FI and precursor symptoms of NEC,and this article provides a review of these developments.
