UAC complications: which is a complication?

• A. Infection
• B. Improved perfusion
• C. Reduced risk of bleeding
• D. No need for imaging

Answer: (A)

When evaluating umbilical arterial catheter (UAC) use in neonates, infection stands out as a real complication. An invasive central line breaches sterile barriers and provides a route for bacteria to enter the bloodstream, leading to catheter-related bloodstream infection. The risk increases with longer catheter duration, handling, and less-than-ideal line care, so strict asepsis, daily site checks, and removing the line as soon as it’s no longer needed help reduce this risk.

The other options don’t represent complications. Improved perfusion is generally a desired effect of monitoring and supporting neonatal circulation, not a problem. Reduced bleeding risk isn’t a benefit of having a UAC; arterial lines can cause bleeding, hematoma, or other vascular injuries. And saying there’s no need for imaging isn’t a complication either—imaging is typically used to confirm catheter placement and monitor position, so claiming no imaging is needed isn’t accurate.
