RESUMO
Objective To explore the relationship between the incidence of hypoglycemia in infants of diabetic mothers and brain injury.Methods The incidence of 86 infants of diabetic mothers combined with hypoglycemia as well as the relationship time of persistent hypoglycemia of infants were studied.And the association of the incidence and degree of brain injury with the time of persistent hypoglycemia,complication of other diseases and symptomatic hypoglycemia was also investigated.Results Seventy-five cases of temporary hypoglycemia(87.2%),and 11 cases of frequent hypolycemia(12.8%)were observed in the study.In the group of unsatisfactory maternal blood glucose control cases,the incidence of frequent hypoglycemia was 19.4%;in the group of satisfactory maternal blood glucose control cases,the incidence of frequent hypoglycemia was 8%.The overall incidence of the brain injury and the incidence of severe brain injury in the group of frequent hypoglycemic cases were higher than those in the group of temporary hypoglycemic cases.The incidence of brain injury in cases complicated with other diseases(77.4%) and in those with clinical symptoms(81.2%) were significantly higher than those in without other diseases(48.5%) and clinical symptoms(57.4%)(Pa
