The analysis of clinical features of neonatal hypoglycemia complicated with necrotizing enterocolitis

Objective To investigate the clinical characteristics,outcomes and risk factors of infants with neonatal hypoglycemia complicated with necrotizing enterocolitis.Methods This study was a retrospective analysis.The clinical data of neonates with hypoglycemia were collected in Xiamen Maternal and Child Health Hospital from January 2014 to December 2019.According to NEC diagnostic criteria and Bell classification criteria(gradeⅡ-Ⅲ),the neonates with hypoglycemia were divided into study group(21 cases).At the same period,neonates suffering from hypoglycemia but did not meet NEC diagnostic criteria were divided into the control group(63 cases)matched by 1∶3 propensity score.The maternal risk factors,clinical symptoms,treatment and prognosis of neonatal hypoglycemia complicated with NEC during pregnancy were analyzed.χ² test,t test and Kruskal-Wallis rank sum test were used for statistical analysis.Results①The proportion of NEC onset in the first 7 days of life was 81.0%(17/21),the median age of onset was 4 days after born.The main clinical symptoms were blood stool,abdominal distention and anepithymia.The cure rate was 81.0%(17/21),the poor prognostic rate was 19%(4/21),and the mortality rate was 4.8%(1/21).②The multiple pregnancy rate28.6%(6/21)vs 4.8%(3/63),χ²=9.993]and the cesarean delivery rate95.2%(20/21)vs 60.3%(38/63),χ²=8.987]in study group were significantly higher than those in control group.The gestational age37.9(37.2,38.8)vs 38.9(38.1,40.0)weeks,Z=-3.198]and the breastfeeding rate9.5%(2/21)vs 31.3%(20/63),χ²=4.023]in study group were significantly lower,than those in control group,and the differences were statistically significant(all P<0.05).Conclusions The onset of NEC in children with hypoglycemia is earlier,bloody stool is the main symptoms.To reduce the incidence of NEC,more attention should be given to the hypoglycemic infants with gestational age less than 39 weeks,multiple pregnancy,cesarean section delivery and artificial feeding.
