The clinical characteristics and risk factors analysis within one week before the onset of necrotizing enterocolitis

Le résumé fourni par la source

There are considerable researches on risk factors for necrotizing enterocolitis (NEC), focusing primarily on the entire course before onset. However, fewer studies address risk factors within the brief period before NEC occurrence. The current study aims to retrospectively analyze the clinical data of NEC patients while focusing on relevant risk factors in the preceding week of NEC onset. Infants born between January 2019 and December 2021 at Suzhou Municipal Hospital and Suzhou University Children's Hospital with a birth weight < 1500 g or a gestational age < 32 weeks were included. Around 54 NEC patients and 180 controls were recruited in the study. NEC patients satisfying the inclusion criteria formed the case group, while a 1:4 matching principle helped select the control group based on gestational age and birth weight. A statistically significant difference was observed between groups when red blood cell transfusions were compared the week before NEC onset (adjusted OR and 95% CI 2.16 (1.10, 4.24)). Broad-spectrum antibiotic usage before NEC occurrence was significantly lower in the NEC group than in the control group (adjusted OR and 95% CI 0.95 (0.91, 0.99)). A statistically significant difference was observed between groups while comparing patent ductus arteriosus (PDA) (adjusted OR and 95% CI 2.45 (1.23, 4.91)). The indication for packed red blood cell transfusion should be strictly controlled. Moreover, close monitoring of the patient's condition for NEC occurrence should be conducted within one-week post-transfusion. Accurately identifying infections and using broad-spectrum antibiotics can reduce the incidence of NEC.
