What glucose value defines neonatal hypoglycemia?

What glucose value defines neonatal hypoglycemia?

• A. Less than 40 mg/dL
• B. Less than 50 mg/dL
• C. Less than 60 mg/dL
• D. Less than 70 mg/dL

Answer: (A)

Neonatal hypoglycemia is defined by a glucose level that falls below the level considered safe for a newborn during the transition after birth. The standard threshold used in most clinical teaching is a blood glucose under 40 mg/dL. This lower limit matters because once glucose drops below about 40 mg/dL, the brain may not receive enough fuel, increasing the risk of neurodevelopmental issues if the low value persists. Infants at risk include those with maternal diabetes, intrauterine growth restriction, preterm birth, or those who have delayed feeding, so screening and early management are especially important in these groups. If a newborn has a glucose below this threshold or is symptomatic (such as jitteriness, poor feeding, lethargy, or apnea), prompt treatment with feeding and, if needed, intravenous dextose, is used to restore glucose and protect brain function.
