Prolonged transitional neonatal hypoglycaemia: characterisation of a clinical syndrome.

Background: We performed a case-control study to characterise infants with "prolonged transitional hypoglycaemia".

Methods: Cases were born ≥36 weeks' gestation; had ≥1 hypoglycaemic episode <72 h and ≥72 h; received ongoing treatment for hypoglycaemia ≥72 h; and were without congenital disorders or acute illness. Cases were compared to controls born ≥36 weeks' with brief transitional hypoglycaemia, resolving <72 h.
