High incidence of respiratory distress syndrome: hyperglycemia stimulates insulin secretion, the latter antagonizes glucocorticoids to promote the synthesis of alveolar type II cell surface active substance, delayed maturation of fetal lung Neonatal hypoglycemia: hyperinsulinemia Treatment: Neonates are prone to hypoglycemia, and final blood glucose measurement should be performed within 30 minutes after birth. All newborns should be treated as high-risk infants, with attention to warmth and oxygen. Feed sugar and milk early, monitor blood glucose dynamically to detect hypoglycemia in time, if necessary, 10% glucose should be administered slowly. Routinely check hemoglobin, potassium, calcium and magnesium bilirubin; pay close attention to the occurrence of neonatal respiratory distress syndrome.
