新生儿坏死性小肠结肠炎的危险因素及早期临床特点.

Objective To explore the risk factors and early clinical characteristics of neonatal necrotizing enterocolitis (NEC), so as to improve the early warning of NEC and early intervention, so as to improve the prognosis of NEC. Methods A total of 95 children diagnosed with NEC in our NICU from November 22, 2017 to November 22, 2020 were collected, and 95 non-NEC children in the same period were selected as the control group according to the 1:1 matching ratio. The univariate variables were screened by χ2 test, and then multivariate Logistic regression analysis was performed. The count data were analyzed by t test and rank sum test, and the rank data were analyzed by Spearman rank correlation test, α= 0.05. Results It suggested that premature birth, low birth weight, infection and mechanical ventilation were independent risk factors for NEC, and abdominal distention and gastric retention were the main clinical manifestations in the early stage. There was no significant correlation between leukocytes and neutrophils and the severity of NEC, while C-Reactive Protein and procalcitonin were positively correlated with the severity of NEC. Lymphocytes and platelets were negatively correlated with the severity of the disease, (P < 0.05). Abdominal orthostatic X-ray had no obvious specificity for the early diagnosis of NEC. Conclusion When the children have the premature birth, low birth weight, infection and mechanical ventilation risk factors, abdominal distension and poor feeding performance, accompanied by the increase of C-reactive protein and procalcitonin, it is necessary to be alert to the occurrence of NEC, and dynamic abdominal orthostatic X-ray and abdominal ultrasound can be performed to improve the early diagnosis rate.
