Introduction
The normal blood glucose range for newborns is 2.2 mmol/L to 7.0 mmol/L. Hyperglycemia or hypoglycemia requires corresponding treatment. Fasting blood glucose below 2.2 mmol/L is considered hypoglycemia, which can be managed by administering glucose water or breastfeeding, or via intramuscular injection or intravenous infusion if necessary. Blood glucose levels above 7.0 mmol/L indicate hyperglycemia; in cases of iatrogenic hyperglycemia, glucose intake should be paused or reduced.
The normal blood glucose range for newborns is between 2.2 mmol/L and 7.0 mmol/L. If hyperglycemia or hypoglycemia occurs, corresponding treatments are required to improve symptoms.
A fasting blood glucose level below 2.2 mmol/L in a newborn indicates hypoglycemia. If caused by physiological factors, symptoms can gradually improve with medical guidance by administering glucose water or timely breastfeeding. For pathological hypoglycemia, prompt medical treatment is necessary. Under physician supervision, treatment may include intramuscular glucagon injections or intravenous infusions of medications such as diazoxide or octreotide. Without timely and effective treatment, hypoglycemic encephalopathy may develop, potentially causing brain damage.
If a newborn's blood glucose level exceeds 7.0 mmol/L, it is diagnosed as neonatal hyperglycemia. For iatrogenic hyperglycemia, it is recommended to pause or reduce glucose intake and adjust the infusion rate accordingly. If dehydration is present, electrolyte solutions should be promptly administered to correct electrolyte imbalances; insulin infusion therapy may be necessary when indicated.
