Current Primary Outcome Measures (submitted: July 2, 2020)

Time spent with glucose <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. ]

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.

Descriptive Information

• Brief Title: Continuous Glucose Monitoring in Infants
• Official Title: Continuous Glucose Monitoring in Infants
• Brief Summary: The purpose of this study is to employ continuous glucose monitoring to measure glucose profiles in newborn infants.
• 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.
• Study Type: Observational

• Target Follow-Up Duration: Not Provided
• Biospecimen: Not Provided
• Sampling Method: Non-Probability Sample
• Study Population: Mother/infant dyads will be admitted at UCSD Jacobs Medical Center for antepartum and postpartum care.
• Condition: Neonatal Hypoglycemia

Intervention
