Study summary

The purpose of this study is to employ continuous glucose monitoring to measure glucose profiles in newborn infants.

Read the detailed description

We will place a continuous glucose monitor on the infant within 2 hours of birth and record blood glucose values every 5 minutes via the monitor; in addition, the infant will receive blood glucose checks via heel stick according to the standard hospital glucose monitoring protocol.

Groups and cohorts

  • No increased risk of hypoglycemia

    Infants born with no obvious risk factors for hypoglycemia in the neonatal period.

    Device: Dexcom continuous glucose monitor

  • Increased risk of hypoglycemia

    Infants considered at increased risk for hypoglycemia after birth including the following criteria: * Infant born to a diabetic mother * Very large for gestational age (VLGA) infant with weight \>97%

    Device: Dexcom continuous glucose monitor

What researchers measure

Primary outcomes

  1. Time spent with glucose <40 mg/dL

    The Dexcom continuous glucose monitors measure interstitial fluid glucose values every 5 minutes. Data obtained from the Dexcom tracings will allow us to quantify how much time both infants with no risk for hypoglycemia (defined here as \<40 mg/dL) and those with risk factors for hypoglycemia spend at a blood glucose of \<40 mg/dL.

    Time frame: The device will be worn from about 2 hours after birth until hospital discharge, up to a maximum of 10 days. It will be removed sooner if required for medical care or if the parent requests removal.
