Persistent hypoglycemia caused by umbilical arterial catheterization

Area of Science:

• Neonatal Medicine
• Pediatric Cardiology
• Endocrinology

Background:

• Umbilical artery catheters (UACs) are common in neonatal intensive care.
• Complications associated with UACs are well-documented but typically involve mechanical issues or infection.
• Hypoglycemia is a known neonatal issue, but rarely linked to UAC placement.

Observation:

• A neonate presented with severe hyperinsulinemic hypoglycemia.
• The infant had a high-positioned umbilical artery catheter that was inadvertently used for parenteral nutrition.
• The catheter's position was implicated as the cause of the hypoglycemia.

Findings:

• The study presents a rare case of hypoglycemia as a complication of umbilical artery catheterization.
• Hyperinsulinemic hypoglycemia was directly linked to a high-positioned UAC used for parenteral nutrition.
• This finding underscores a previously unrecognized risk associated with UACs.

Implications:

• Increased physician awareness is crucial for recognizing and managing this rare UAC complication.
• Proper UAC placement and monitoring are essential to prevent inadvertent parenteral nutrition administration.
• This case may prompt revised guidelines for UAC use in neonates, particularly regarding nutrition delivery.
