Abstract

Hypoglycemia is one of the most common presenting complaints at a pediatric emergency department. There are many distinct causes of hypoglycemia, ranging from nutritional insufficiency to infectious origins to metabolic disorders. Full clinical assessment and appropriate investigations can help differentiate the cause of hypoglycemia with subsequent tailored management. All patients with hypoglycemia should have a full clinical assessment together with a hypoglycemia screen if appropriate. This clinical review aims to determine the investigation of hypoglycemia in young children (<6 years) and whether these patients received a subsequent diagnosis and adequate follow-up plans.

The laboratory database searched for all children from 0 to 6 years old, with hypoglycemia defined as plasma glucose (PG) <54.0 mg/dL (or <3.0 mmol/L) from 2013 to 2021 at the Royal Hospital of Children, Glasgow. Cases were reviewed for the biochemistry investigations to determine if they had hypoglycemia screening requested and/or performed the presenting complaint, clinical diagnosis, and subsequent follow-up arrangements.

Five hundred and one children were identified with hypoglycemia (PG <54.0 mg/dL) over a 9-year period. Of these patients, 28% (142/501) had a full hypoglycemia screen, 38% had a partial screen, and 34% (166/501) had no additional blood tests related to hypoglycemia screening other than a PG. The cause of hypoglycemia was identified in 15% (77/501), with gastroenteritis being the…
