Objectives Describe clinical characteristics, course, and risk factors for hyper-insulinemic hypoglycemia (HIH) in preterm infants and identify impediments to early diagnosis. Methods Electronic records of infant–mother dyads were used to describe clinical characteristics, lab parameters, and course of HIH. Results All eight patients (gestational ages 26w0d–29w3d) had intrauterine growth restriction (IUGR) due to placental insufficiency, (4/8) were small for gestational age. All maintained normal glucose levels with glucose infusion during the first 48 h six of eight patients had cholestasis despite being on parenteral nutrition for short time (average 17 days). Four of eight patients were treated with diazoxide (average 22 days). Four of eight patients who recovered spontaneously (average 49 days after diagnosis) responded to continuous feeds and hydrocortisone for other clinical indications. Conclusions In IUGR preterms, HIH is asymptomatic, may be prolonged, requiring diazoxide treatment. Transient cholestasis is seen in majority of patients. Euglycemia should be demonstrated on bolus gavage feeds, off glucocorticoids before discontinuing blood glucose monitoring.
