👶 Neonatal Hypoglycemia Thresholds and Management
This tool gives age-stratified operational glucose thresholds and targets for at-risk newborns, combining AAP 2011 transitional thresholds with PES treatment targets.
Neonatal Hypoglycemia Thresholds and Management
Postnatal age
Blood glucose (mmol/L)
Hypoglycemia symptoms (tremor / irritability / apnea / seizures / lethargy / poor feeding)
When to use
Use when screening or managing glucose in at-risk newborns (preterm, SGA, LGA, infant of a diabetic mother, perinatal asphyxia) in the first days of life.
How it works
Symptomatic + glucose < 2.2 mmol/L → IV glucose emergency. AAP thresholds: < 4 h < 1.4, 4–24 h < 1.9 mmol/L (feed, recheck, IV glucose if persistent). PES targets: > 2.8 first 48 h, > 3.3 after 48 h, > 3.9 if suspected congenital disorder.
Key points
- Symptomatic hypoglycemia with glucose below 2.2 mmol/L is a neurologic emergency requiring immediate IV dextrose and a search for the cause.
- Thresholds are operational, not a unified gold standard; management prioritizes early feeding and rechecking before escalating to IV glucose.
- Persistent inability to maintain targets, or hypoglycemia beyond 48 hours, prompts investigation for a congenital disorder with critical samples drawn before discharge.
