新生儿低血糖症指新生儿血糖值低于健康新生儿的最低血糖值,目前新生儿低血糖症的界限值尚存争议[1-2]。国外认为健康新生儿出生24 h内空腹血糖2~2.5 mmol/L,低于此值即为新生儿低血糖症[1]。国内以生后血糖低于2.2mmol/L为低血糖症诊断标准,血糖低于2.6 mmol/L为干预标准[3]。高胰岛素血症性低血糖症是新生儿低血糖症的常见原因之一,近年逐渐为人们所认识和重视。胰岛素是调节血糖的主要激素之一。血糖增高时胰岛素分泌增加以降低血糖水平;反之,血糖降低时胰岛素 Neonatal hypoglycemia refers to the neonatal blood glucose lower than the healthy newborn blood glucose, the current limit of neonatal hypoglycemia is controversial [1-2]. Abroad that healthy newborns within 24 h of birth, fasting blood glucose 2 ~ 2.5 mmol / L, below this value is neonatal hypoglycemia [1]. Domestic postnatal blood glucose less than 2.2mmol / L for the diagnosis of hypoglycemia, blood glucose lower than 2.6 mmol / L for intervention [3]. Hyperinsulinemic hypoglycemia is one of the most common causes of neonatal hypoglycemia, which has gradually become known and valued by people in recent years. Insulin is one of the major hormones regulating blood sugar. Increased blood glucose insulin secretion to reduce blood glucose levels; the other hand, lower blood glucose insulin
