Relationship between neonatal asphyxia and blood glucose disorder / 中华围产医学杂志

ABSTRACT

Objective To study the association between neonatal asphyxia and blood glucose disorder. Methods A total of 134 cases of neonatal asphyxia born in the Maternal and Child Hospital of Hubei Province between January 2013 and January 2015 were included in this study. Blood glucose levels were determined within 30 min after birth and before glucose infusion. The infants were divided into the mild asphyxia group (Apgar score 4 to 7) and severe asphyxia group (Apgar score 0 to 3) according to the Apgar score at 5 min after birth. Statistical analyses were performed using the two-sample t-test and Chi-square test. Results The incidence of asphyxia was 3.2‰(134/41 875). Hypoglycemia was the main blood glucose disorder in the mild asphyxia group [12% (13/112)], and hyperglycemia was the main blood glucose disorder in the severe asphyxia group [32%(7/22)]. The average blood glucose level was higher in the severe asphyxia group than in the mild asphyxia group [(5.8±3.4) vs (5.0±2.3) mmol/L, t=21.979, P=0.001]. In the severe asphyxia group, the incidence of hypoglycemia was higher [18% (4/22) vs 12% (13/112), χ2=7.464, P=0.006] and the average blood glucose level was lower [(1.8±0.7) vs (2.1±0.4) mmol/L, t=5.247, P=0.042],and the incidence of hyperglycemia was also higher [32% (7/22) vs 9% (10/112), χ2=11.679, P=0.001] and the blood glucose level was higher [(11.6±3.8) vs (9.3±2.0) mmol/L, t=1.106, P=0.048]. Conclusion Neonatal asphyxia can lead to blood glucose disorders. The incidence and the severity of these disorders were higher in neonates with severe asphyxia.
