[Value of intestinal regional oxygen saturation and C-reactive protein in the diagnosis of necrotizing enterocolitis in preterm infants].

Objectives: To study the clinical value of intestinal regional oxygen saturation (rSO) and C-reactive protein (CRP) in the diagnosis of necrotizing enterocolitis (NEC) in preterm infants.

Methods: A prospective observational study was conducted among the preterm infants who were hospitalized in Children's Hospital Affiliated to Anhui Medical University, from October 2020 to December 2021, with 22 infants in the NEC group and 35 infants in the non-NEC group. Intestinal rSO was monitored 24 hours after a confirmed diagnosis of NEC in the NEC group, and serum CRP levels were measured before anti-infection therapy.
