[Umbilical artery catheterization. A simplified method to predict the catheter localization (author's transl)]

Area of Science:

• Neonatal medicine
• Pediatric radiology
• Vascular access

Context:

• Umbilical arterial catheters (UACs) are crucial for neonatal monitoring.
• Accurate UAC tip placement in the thoracic aorta is vital to prevent complications.
• Current methods often require repeated radiographic confirmation.

Purpose:

• To present a simplified, reliable method for predicting UAC distal tip localization in the thoracic aorta.
• To reduce the need for corrective catheter repositioning and repeated X-rays.

Summary:

• A novel technique involves introducing a specific length of the UAC, equal to one-third of the infant's length in centimeters.
• This method achieved correct placement (between vertebral bodies T6-T10) in over 90% of cases.
• The simplified approach avoids the necessity for catheter adjustments and additional radiographic controls.

Impact:

• Enhances patient safety by minimizing radiation exposure and procedural interventions.
• Improves efficiency in neonatal intensive care units.
• Provides a practical, evidence-based guideline for UAC insertion.
